IPC: A63B47/00
Filed: 1983-03-16
Abstract: A soccer ball practice machine 10 includes a pair of juxtaposed, oppositely rotating wheels 12 for propelling a soccer ball 14 toward a soccer player to facilitate the practice and instruction of a wide variety of soccer skills. The orientation of these wheels can be selectively varied to permit the soccer ball to be propelled in an infinite number of directions. In addition, the distance separating the rotating juxtaposed wheels can also be adjusted to accommodate soccer balls of varying diameters and can be automatically increased to prevent damage to oversized balls due to engagement by the wheels. A large hopper 16 includes a rotating auger which successively feeds soccer balls in the hopper into a flexible feed tube 20 and down a rigid ball chute 22 where they are engaged by the wheels and propelled outwardly. The flexibility of the feed tube and the rigidity of the ball chute provide accurate delivery of the balls to the wheels and confinement of the balls on all sides as they are engaged and propelled by the wheels, even though the positions of the wheels relative to the hopper may be changed to vary the direction of the ball's flight. <IMAGE>

Title: Fabricating couplers in optical fibres by fusing
Inventor: ARNOLD LESLIE JOHN
IPC: G02B6/28
Filed: 1984-03-09
Abstract: A method of fabricating couplers in optical fibres, for example two fibres (5, 6) forming an X coupler, involves traversing a flame along the coupling region (7) of the fibres in an oscillatory motion and simultaneously stretching and twisting the fibres to give a symmetrical and smooth biconical taper. The oscillatory motion is performed in such a way that the part of the fibres at the ends of the oscillatory stroke do not become hotter than that part at the centre of the stroke and so either the speed of the flame increases, or the flame moves away from the fibre, towards the ends of the stroke. <IMAGE>

Patent GB-2171875-A (GB)
Title: Superimposing video images
Inventor: ASTLE BRIAN
IPC: H04N5/272
Filed: 1986-02-18
Abstract: Computer generated or other video objects 18 may be superimposed over a background video image 14 so as to create the illusion of a single composite scene. The leading edge of an object is detected by one-shot 22 and for a period of time set by one-shot 22 the object 18 and background video 14 signals are mixed. After that period, only the object video 18 is transmitted. Upon detection of the object's trailing edge by one-shot 28, the two video signals are again mixed for a period of time set by one-shot 28. After this latter period, only the background video signal 14 is transmitted until another object's edge is detected. The mixing of the signals at the edges of the object produces a blending of the object into the background scene so that the object appears to be more realistically part of a single scene. The area of the foreground video signal around the object is maintained at a "blacker-than-black" level to ensure that object detail is not mistaken for an edge. Inverter 26 is provided since the one-shots trigger only on positive-going transitions. The delays 12, 20 are about half of one pixel period. <IMAGE>
