	Golf putter - Patent 4881739
		Both the horizontal plane and the axis of the ball-striking face are located essentially 0.84 inches from the sole.
		A ball being struck is precluded from being struck by the putter head above the horizontal plane due to the distance between the horizontal plane and the sole being essentially the same as the radius of curvature of the ball to be struck.
		Both the horizontal plane and the axis of the ball-striking face are located essentially 0.84 inches from the sole 26 and green 28 of as close as possible thereto with the curved face extending downwardly from the horizontal plane.

	Horizontal Mill (Site not responding. Last check: 2007-10-29)
		The primary difference between the vertical milling machine and the horizontal milling machine is the location of the spindle.
		Although drill work is performed on horizontal mills, as a rule horizontal milling machines do not have a quill that extends from the spindle for drilling, boring, etc. Horizontal mills are able to utilize cutters and attachments that normally would not be practical to use on vertical machines.
		A horizontal milling machine performs face cutting directly from the spindle and using an arbor is able to employ single or multiple cutters known as gang milling (figure 1), allowing side, face, and form machining in one operation.

	Faulty Reasoning
		The strike is the bearing of a horizontal line in the plane, the intersection of the plane with the horizontal plane, and is usually specified by the bearing to the east or west of north, from 0° to 90°.
		The dip is the angle between the trace of the horizontal plane and the trace of the plane under consideration in a plane normal to the strike, a dip plane.
		In the horizontal plane, the stratum is displaced from A to B along the fault trace.

	Page 10 -- What is an Earthquake?
		A fault plane is a plane used to represent an actual fault, or a particular segment of a fault.
		However, since faults do typically act as planes (even though some, in fact, are so physically complex that trying to draw their structure would be cumbersome and confusing), defining a fault plane is the most convenient way to represent and model a fault.
		Here, the horizontal plane shown is that of sea level, but a horizontal plane of any altitude or depth can be used for reference.

	DNB - Choreutics
		Because they were conceived as dimensional planes, each was named with the dimension which is its largest component, namely the 'vertical plane' is lengthened along the vertical dimension, the sagittal plane is lengthened along the sagittal dimension, and the horizontal plane is lengthened along the horizontal dimension.
		In this case they are not 'dimensional planes' at all and so the question arises as to whether it makes logical sense to conceive of these types of planes according to the same concepts as the planes which are lengthened along one of the dimensions.
		In the face of these variously shaped cardinal planes it may be clarifying to develop concepts which are not specific to only one type of planar shape (the traditional 'dimensional planes'), but can be applied in the analysis of all types of possible planar shapes.

		I explain plane reflections — as from a mirror, or the surface of a large body of water — with a brief description of reflections from waves in water and curved reflecting surfaces such as a metallic globe.
		The light plane vanishing line for the horizontal edge, lpvl [horizontal], must be found as a line from the light vanishing point lvp to the vanishing point for the structure casting the horizontal shadow, svp [horizontal], as described under shadow type 2.
		The shadow vanishing line is still the intersection of two planes, the light plane and the surface plane; and the length of the shadow is still determined by a line from the center of the light to the end of the edge, as described for shadow type 1.

	CUBICAL PROJECTIONS
		The vertical sides of the cube’s visible square represent a set of square planes that are vertical and the horizontal sides of the cube’s visible square represent the other set of square planes which are horizontal.
		Together these 3 sets of planes (one horizontal, one vertical, and one directly visible) represent the latticework of the cube which is comprised of 3 sets of infinite co-planes.
		Viewing this scenario locally from the surface of the earth (with the visible profile plane facing west), the vertical plane of the imaginary column from the celestial cube becomes a south facing plane while the horizontal plane of the column becomes a north facing plane.

	Mark-II optical paths
		Design of the horizontal scanning assembly involves the use of a set of tiled galvanometric scanners, mounted in a configuration designed to minimize the width (and inertia) of each mirror and shrink the gaps between them.
		Because the system's vertical focal plane is fixed and horizontal focus is variable, deep images exhibit some astigmatism, just as they do in any horizontal-parallax-only display.
		For an image plane aspect ratio of 2:1, (where the image plane measures 150mm across and where the 75mm vertical extent of the image plane is determined by a stack of 8 sweeps --4 forward and 4 reverse-- of the AOM's image) the required magnification is 75mm / (8*67mm) = 0.14.

	RC Design: Horizontal Tails
		Horizontal tails, the good old stabilizer and elevator, are extremely important to the performance of your airplane.
		First, it is generally accepted the horizontal tail area, combined stabilizer and elevator areas, should be a minimum of 20% of the wing area.
		With an exact scale wing, the plane would have a very high wing loading and be difficult to fly and land.

	The Arrow in the Eye: Chapter II: The Elements of Perspective (page 6)
		Proposition 3: The perspectival images of parallel lines that are neither parallel nor perpendicular to the picture plane converge onto a vanishing point at some location away from the principal vanishing point (and which is not necessarily within the confines the picture).
		Any two horizontal lines that are parallel to each other intersect the horizon line at the same point, which is their horizontal vanishing point.
		Had we described it as the picture of a slanted box projected onto a vertical picture plane, we would have had to relabel the vanishing points, for the box would have neither horizontal nor vertical surfaces and the vanishing points of the cube would therefore not lie on the horizon line.

	Staten Island Lasik Eye Surgery (Site not responding. Last check: 2007-10-29)
		In the normal eye, light travelling through the cornea in both the horizontal plane (blue) and vertical (red) plane is refracted (bent) the same, so that the image is properly focused on the retina in the back of the eye.
		With astigmatism, (place cursor over image), an abnormal curvature of the cornea in one direction causes light travelling in one plane, the horizontal (blue) plane in this case, is focused in front of the retina.
		The light striking the retina through the horizontal plane is out of focus on the retina and vision is unclear.

	The Cartesian Plane
		The position of a point on a Cartesian plane is represented by referring to it in terms of a horizontal line and a vertical line, which are called the x-axis and y-axis respectively.
		The position of any point on the Cartesian plane is described by using two numbers, (x, y), that are called coordinates.
		The first number, x, is the horizontal position of the point from the origin.

		In these types of special cases, the AHJ will need to define the datum plane in conformance with the performance requirements of the system being installed, and the project-specific definition so developed may not be consistent with any other prevailing local definition that they may have created for general use.
		Equipotential planes, defined in 682.2, are constructed of solid metal, wire mesh or "other conductive elements" (generally rebar or solid copper conductors) located on (e.g., metallic safety tread), within, or within 3 in.

They are not required for the controlled equipment.
