Title: Apparatus for playing a simulated ball game
IPC: A63F9/00
Filed: 1975-02-28
Abstract: 1477058 Screen game CREMEAL SA 28 Feb 1975 [1 March 1974 12 July 1974 (2)] 8485/75 Heading A6H A tennis type game comprises a translucent screen through which a point 2 representing the ball and rectilineal segments 3 representing rackets are visible, manual controls 16 for moving the rackets and means 5, 6 for producing a zig-zag path of the ball across the screen. The members 2 and 3 are luminous. The "ball" 2 is moved across the bar 6 by a motor 9 and chain or belt gearing, the bar 6 being similarly moved transversely by a motor 10. A sliding rod 13 is engaged by the bar 6 to reverse the motor 10 through a switch 14. If a vertical rod carrying the ball 4 hits a racket 3, a frame 15 is moved to actuate a reversing switch 20 and the ball is returned. If, however, the ball-rod hits a transverse rod 19, a catch 24 on the rod, Fig 2, is released to allow a spring-actuated rod 23 to move leftwards and actuate a motor stop switch 22. When the switch 22 is reset by pressing back the rod 23 manually, a scoring device 27 is actuated.  In a modification, the ball 2 is carried by cross-slides driven by rack-and-pinion gearing, the driving motors being reversed by switches on the slides, the transverse slide carrying projections which actuate score counters if the ball does not hit a racket. The engagement of the "ball" with the reversing means produces a noise to simulate the rebound noise of the ball.

March 21, 1936, No. 8534. [Classes 80 (i) and 80 (ii)] A two-speed gear for a cycle comprises a spur planetary train in which each gear element is divided into parts on both sides of a disc 40, Fig. 2, which supports divided interengaging planets 4, 41 and 14, 14<1>, Fig. 1. This dividing disc 40 is supported in a groove on a ball 411 between the parts 3, 31 of a divided sun gear and extends into a groove between the parts 10, 10<1> of a divided annulus. The annulus 10, 101 is rigid with a driven chain-wheel 11 and the sun gear 3, 3<1> with a wheel 1 rigid with the crank axle, not shown. The two speeds are a solid drive, and a reduced speed by holding the disc 40 against rotation, the interengaging planets causing the annulus 10, 101 to turn in the forward direction, balls 41 eliminating friction. The disc 40 is rigid with a casing 44 bent over as shown in Fig. 2, and when a spring latch 60 is in the position shown in that figure and in Fig. 3, the gearing is operative to reduce the speed. A clutch dog 47 projecting from a ring 46 slides radially over dog ears 43, 43<1> rigid with the wheel 1. During geared driving, the dog 47 sweeps round idly as shown in Fig. 3. On withdrawing the latch 60 by hand, the dog 47 is snapped by springs 50 into a recess 451 in the casing 44 vacated by the latch so as to lock the planetary train solid for high speed.

Abstract: In a process for the separation of iron from bauxite, the bauxite mixed with solid fuel is subjected in a rotary tubular furnace at 900--1400 DEG  C. to a reducing process such that only the iron is reduced, the sponge iron so produced being converted into lumps by the admission of oxidizing gases, the alumina remaining in the slag. Alkalies or sulphiding agents such as soda or gypsum may be added during the process, the final slag then being lixiviated to enable the alumina to be separated and the slag associated with the iron lumps being also similarly treated to obtain the alumina contained therein.  Specification 402,743, [Group II], is referred to.ALSO:In a process for the separation of iron from ores containing, in addition to iron, metals which are more difficult to reduce than the iron, the ores, mixed with solid fuels, are subjected in a rotary tubular furnace at 900-1400 DEG  C. to a reducing process such that only the iron is reduced, the sponge iron so produced being converted into lumps, the other metals remaining in the slag, by the admission of oxidizing gases.  The process may be applied to the treatment of bauxite to produce pure alumina.  The oxide of the metals present other than iron, such as manganese chromium, tungsten and vanadium may be decomposed simultaneously with the iron by the addition of alkalies or sulphiding agents such as soda or gypsum.  When these substances are added during the treatment of bauxite the final slag may be lixiviated to enable the alumina to be separated and the iron lumps and slag containing alumina may be similarly treated to obtain the alumina contained in the slag.  Specification 402,743 is referred to.
