		Loop quantum gravity (LQG), also known as loop gravity and quantum geometry, is a proposed quantum theory of spacetime which attempts to reconcile the seemingly incompatible theories of quantum mechanics and general relativity.
		At the core of loop quantum gravity is a framework for nonperturbative quantization of diffeomorphism-invariant gauge theories, which one might call loop quantization.
		Quantum Gravity and the Standard Model-- Shows that a class of background independent models of quantum spacetime have local excitations that can be mapped to the first generation fermions of the standard model of particle physics.

	Supplemental coin acceptor/rejector mechanism for coin operated machines - Patent 4220234
		The chute is automatically pivoted between gate open and gate closed positions in response to this microswitch and another microswitch sensing acceptance of a predetermined number of proper value coins of different size and weight to insure return of superfluous coins to the operator, in any sequence.
		The mechanism further comprises a solenoid operatively coupled to the discharge chute such that energization of the solenoid causes the chute to pivot about its lower edge such that the chute opening is laterally displaced relative to the discharge path for rejected coins from a position intersecting that path to one laterally displaced therefrom.
		Since the gravity flow path for the coins which are not accepted by the primary or first acceptor/rejector mechanism 14 is defined by the aligned openings or slots 18 and 42, it is important that the opening 66 within the upper end 68 of the chute be properly positioned with respect to this flow path.

	Chutes and Bucket Tramways
		This chute, constructed of four inch boards nailed into a square pipe, was 3,200 feet long and dropped 1,700 feet into the river canyon.
		Truax tried constructing a chute made of tin, coating the inside of his chute with glass and installing side chutes to reduce the speed of the falling grain.
		Kelly's Chute began life as a tin grain chute in 1881 and converted to a bucket tramway in 1893.

	Pilot Attached Drogue
		The PAD chute is a small, simple drogue chute designed to be reliable and effective when deployed from a hang glider pilot's harness.
		The pilot-attached drogue chute is intended to be a convenience, not an emergency device, since it cannot be relied upon to deploy with complete reliability or promptness in critical situations.
		The drogue chute is no panacea for poor landing skills or other flying problems (plenty of aluminum has been broken using drogue chutes), but it helps.

	Parachutes
		Gravity is constant, but air friction changes with velocity.
		But as the parachutist slows down, the frictional force decreases until it approximately equals the force of gravity, and a new terminal velocity is reached.
		After the chute opens, a net upward force causes a positive acceleration which initially is great and then becomes small.

	Unloader for ring-shaped pallets
		A workpiece having an enlarged head and a stem extending therefrom is conveyed in a gravity chute while supported vertically in a ring-shaped pallet with the head supported on the top side of the pallet and the stem extending downwardly through the pallet.
		The ring-shaped pallets carrying the workpieces and travelling downwardly in an inclined gravity chuting are arrested by an escapement mechanism which meters the loaded pallets one at a time as they exit from the gravity chuting.
		On the side of chute 34 directly opposite unloading chute 44 there is arranged a block 50 which cooperates with the bottom wall 48 of chute 44 to arrest the downward movement of the workpiece in the inclined position shown in FIG.

	Flight Training and Instructions for Ultralights,and Powered Parachutes.
		C. You should be familiar with all major components of the craft and chute, what their purpose is, and how to operate them.It is recommended that the pilot spend a good amount of time just sitting in the craft familiarizing himself long before he attempts to fly the craft.
		If the chute is lagging to your left as you look up at it, then the wind is coming from your right and you must push the control stick right to turn the craft to the right.
		Although you can expect the chute to reinflate after a brief period of freefall, severe wind shear is very hazardous to all aircraft and is to be avoided at all cost.

	Golf ball handling system - Patent 5350260
		The balls move downwardly from the hopper into a tank were they follow a path through the tank and are washed by a rotating brush as the balls move along a path defined by the tank from an inlet end to an outlet end of the washer.
		A chute is provided for directing the balls from this storage area preferably by gravity toward a rotating drum where the balls are formed into predetermined groups or charges.
		The rotatable drum has a plurality of radially outwardly open pockets, and means is provided for periodically rotating the drum from a first angular position such that the balls move by gravity from the chute into one pocket to a second angular position such that the balls move by gravity out of a second pocket.

	RETURN OF THE PIRANHA
		A gravity slide chute let autos and other scrap gravity feed into the maw of the feed roller as the material dropped from the end of the feed conveyor into the chute.
		The operator was able to control the rate of feed from the control tower next to the shredder by regulating the speed and action of the hydraulic roller as the scrap came down the slide chute into the roller throat.
		The motors, gas tanks, and transmissions had been removed from the large autos; the 4-cylinder smaller motors and transmissions in the compact cars were drained of oils and fluids and left in the bodies.

	Recovery Systems
		Your chute could be larger but some rocket styles have narrow nosecones and the chute could get stuck.
		Dust the chute with baby powder to ensure that it doesn't stick to the side of the rocket or itself.
		If you find that the chute area is too small to hold your parachute, you can increase the size of container by adding a section of chipboard around the girth of the bottle.

	Selecting a feed system for roll press success
		The major advantage of a gravity feed slide gate is its ability to use wide roll widths that are not possible using a single screw, and the ability to handle lumpy materials like cement clinker that otherwise would shorten the life of a screw because of excessive wear.
		For powders, perforating the sides of the chute and the tongue allows air to escape, which is essential for achieving high powder flow rates.
		The chute level automatically varies to exert the proper feed pressure on the rolls.

		Standing in a basket at the end of the pole, he released his chute and then oscillated (swung back and forth) violently as the unvented (no hole in the top) canopy spilled air from one side and then from the other.
		Although the effects of gravity are reduced, it is not completely eliminated (removed) The speed of fall, however, is decreased to a much safer 14 miles an hour.
		The harness is specially constructed so that the parachutist is not injured as the forces of deceleration (slowing down), gravity and wind are transmitted (sent) to the wearer's body as the chute opens.

	Mars Pathfinder FAQs - EDL
		Our chute on Mars is about the equivalent of a chute 38 times smaller in area on Earth (6.5 ft across!), and this includes the effect of Mars' lower gravity!
		Remember, the drag FORCE a chute generates (therefore its deceleration), is proportional to the square of the velocity and only linearly proportional to the atmospheric density; so even a thin atmosphere and a "small" chute will do much to slow our entry vehicle down once the heatshield's aerobraking has been mostly achieved.
		For chutes that open up at low speeds (say after a drag chute has slowed the lander down), then maybe the problem could be solved more cost effectively.

	TR: 8/28 North Peak - Kook Chute - Teton Gravity Research Forums
		Granted it wasn't the 60+ that I ran into at one particular chute this spring, but this was enough to grab your attention when you hadn't seen the chute from any other angle.
		If so, that's Kidney Chute (drops off the plateu to Kidney Lake) and I think the best approach would be from the Gibbs Lake trailhead (395 to Horse Meadow Road) -- 3 miles on a trail to Gibbs Lake, then a mile of scree to Kidney Lake.
		The chute is painfully obvious when you are driving north on 395 as you approach Lee Vining.

		Using balance equations, constitutive relations, and boundary conditions that result from kinetic theory, we calculate the fields of mean velocity, fluctuation velocity, and concentration accross the chute, for a variety of flow rates, particle parameters, and chute width.
		We find that, given particle parameters and chute width, within a certain range of volume flow rate there are two qualitatively different steady flow regimes.
		For dense slow flow, as the chute width is decreased, average concentration decreases and average mean velocity increases, i.e., the flow tends towards the dilute fast flow regime and vice versa.

	Cleveland Roller Mill Online Tour (page2)
		This mill stand contained the "break" rolls (very rough) that would start the grinding process by "breaking" the bran outer hull of the wheat and subsequent smoother rolls would continue the grinding until all possible flour, bran, and germ was extracted.
		The long vertical wooden items in the foreground are gravity chutes, part of the semi-automatic transport system used to move wheat and flour around the mill.
		Elevators, consisting of continuous looped belts with small buckets, would dump the product into the gravity chute, where it would slide down to the next machine or bin.

	Gravity-May the Force Be With You
		Gravity, or “gravitation,” is the universal force of attraction that tries to pull every piece of matter together.
		The activity, Galileo’s Marble Chute, is based on a chute Galileo created to test his theory that gravity causes falling objects to move faster.
		Also, the longer the chute is, the easier it is to hear the acceleration of the marble.

	CarterCopter - Description of the CC's Ballistic Recovery Chute
		Once the chute is out of the bag and the 5/16 cable is stretched tight, the thrust and inertia of the rocket breaks the 500 pound strength cord attaching the chute to the bag.
		The chute will not see more load than the full weight of the aircraft until the aircraft has completely spun around and the aircraft center of gravity is lined up with the cable.
		The chute is not designed to be deployed at our test weight at a sea level speed greater than 200 mph, but since the aircraft is forced to rotate sideways before the full force is seen by the chute, we expect the speed might drop 40 mph during this manuver.
