  Ball Transfer Units - The Largest Range in The World - Alwayse Engineering Limited
As originators of the Ball Transfer Unit, we have become an integral part of the Material handling industry.
The name 'Alwayse' derives from the multi-directional nature of the ball transfer unit - they move in all directions enabling the easy transfer of light and heavy loads, and the direction of motion to change instantly.
Alwayse Ball Transfer Units are used in industries throughout the world.

  PlanetMath: unit disc
Unit discs are a special case of unit ball.
With the standard metric, unit discs look like circles of radius one, but changing the metric changes also the corresponding set of points and therefore the shape of the discs.
This is version 2 of unit disc, born on 2006-03-18, modified 2006-03-18.

 Ball transfer unit - Patent 5516211
Ball transfer units, sometimes referred to as conveyor ball units, are commonly used in connection with conveyor tracks for the movement or handling of freight, such as the loading and unloading of cargo from an aircraft.
Ball transfer units currently known in the art are often subjected to corrosive chemicals, particulate contaminants, and fluids which enter the race of the housing and cause the surface of the conveyor ball to corrode and wear.
The annular seal 18 is a floating seal, and thus not fixedly attached to the conveyor ball unit 5.

 Unit sphere - Wikipedia, the free encyclopedia
In mathematics, a unit sphere is the set of points of distance 1 from a fixed central point, where a generalized concept of distance may be used.
A unit ball is the region enclosed by a unit sphere.
Therefore one speaks of "the" unit ball or "the" unit sphere.

 Inside Your Bingo - Ball Lifter
Almost all bingo machines have automatic ball lifters; that is, a motorized unit that raises each ball up to playfield level, instead of using a manual ball lifter as in most other pingames of the same period.
Attached to the playfield is a relay, the lifter start relay, and two switches connected with the ball runway (the channel running from the ball shooter to the top of the playfield through which each ball passes when first shot by the player).
When the ball is shot, and leaves the runway, it pushes up on the ball gate switch, momentarily opening its contacts, thus dropping out the lifter start relay.

 Conveyor ball unit - Patent 5033601
Conveyor ball units of that kind are used for example in ball-type conveyor tracks which are provided for example in the freight compartment of a freight aircraft, for moving freight containers when loading or unloading the aircraft.
A conveyor ball 1 is rotatably mounted on the mounting balls 15.
In that condition nonetheless the conveyor ball unit is still guaranteed to be securely held together as a unit as the locking shoulder 35 still engages under the rim or flange portion 12 of the mounting shell 10.

 DP F1999M: Crystal Ball Diplomacy
Units hold by default if no order is issued to them, and it would be foolish to waste one of your precious orders on such a command.
Since you have four of your own units to be ordered, you will either have to allow one of your own units to hold by virtue of being left unordered, or issue a proxy for it to another power and hope he serves you well with it.
However, a smaller power -- especially one that knows where all of his units are -- is an invaluable aid to an ally, as he can order units proxied to him in case certain earlier moves bounced or if any unit had to retreat to a new position.

 Ball Bearing offers concentric mounting., SKF USA Inc.   (Site not responding. Last check: 2007-10-11)
Unlike conventional set-screw bearing units, which contact the shaft in only three places, the SKF ConCentra Air Handling Ball Bearing Unit employs a patented multi-step sleeve arrangement to form a near 360-degree interference fit with the shaft.
During installation, as set screws are tightened, the bearing unit's inner ring is moved up a series of inclined planes, compressing a sleeve around the shaft.
The unit is available in pillow block and two- and four-bolt flange versions.

 Mudd Math Fun Facts: Volume of a Ball in N Dimensions
The 1-dimensional volume (i.e., length) of the unit interval [-1,1] is 2.
The 2-dimensional volume (i.e., area) of the unit disc in the plane is Pi.
Therefore, as n tends to infinity the "coordinate threshold" Sqrt(1/(n-1)) effectively squashes the unit ball into thinner and thinner spikes around each of the coordinate axes, forcing its n-dimensional volume to 0.

Linear maps on factors which preserve the extreme points of the unit ball
The aim of this paper is to characterize those linear maps from a von Neumann factor $\A$ into itself which preserve the extreme points of the unit ball of $\A$.
For example, we show that if $\A$ is infinite, then every such linear preserver can be written as a fixed unitary operator times either a unital $\ast$-homomorphism or a unital $\ast$-antihomomorphism.

If, then the closed unit ball in E is compact by the Bolzano-Weierstrass theorem because it is closed and bounded.
.Therefore this infinite set does not have any accumulation point, hence the closed unit ball can not be compact.
Therefore if the unit ball is compact, then X should be compact too.
