H. ; 10, Bridge Street, New York, both in U.S.A.) Nov. 4, 1929, No. 33540. Convention date, Nov. 5, 1928. [Class 98 (ii).] A kinematograph film comprises two film layers 1, 2, with magnetic material constituting a sound record track 3 embedded between them, and a coating of cementitious material 5, 6, on either or both the opposed faces of the film layers as shown in Fig. 3. The upper film layer 1 may carry the photographic emulsion. The sound track 3 may be in the form of a ribbon or of magnetic granules. If desired, the lower film 2 may be of narrower width than the upper film 1 so as to extend between the sprocket holes of the combined film. During manufacture of the combined film, the photo-transparent films 1, 2 may be fed from reels 11, 8 over guide rollers 9, 10, 13, 12 as shown in Fig. 4, and coated with cementitious material from containers 16, 14. The sound track may be fed between the two films from another reel when the track is in the form of a ribbon and from a vibrated container 29 when in the form of granules. The container 29 is suspended on a rod 32 and vibrated from an electrically-operated arm 34. A magnet 35 may be arranged under the container 29 in order to obtain a uniform flow of magnetic material on to the film. The films are fed forwardly by means of sprocket-wheels 21, 25 and pressure rollers 22, 26, and between pairs of rollers 19, 20, 23, 24. The combined film is wound on to a drying-drum which is given both a rotary and translatory motion so as to prevent overlapping of the film. If desired, a number of sound tracks may be mounted between a pair of wide films, and the finished structure is cut so as to provide a number of combined films of the required widths. Each film may be provided with a single sound track of granular form, or with two ribbon tracks disposed at opposite sides of the film.

Title: Variable speed drive system for carding machine
IPC: D01G15/36
Filed: 1976-08-16
Abstract: 1532074 Carding engine drive system CANTON TEXTILE MILLS INC 16 Aug 1976 [18 Aug 1975] 33977/76 Headings DID and DIN In a carding process the feed and doffing mechanisms are driven at a fixed speed ratio via a variable speed drive and, as the process begins after a predetermined time, during which these components are driven at a slow speed, if sliver is sensed entering a coiler can the speed is gradually increased to a constant speed, but if no sliver is sensed the drive to these components is terminated. The system which operates this process has a V belt drive 25 extending about cone pulleys of variable pitch to alter the drive speed, the pitch variation being variably limited to set the high running speed. The pitch of pulley 49, Fig. 2, is altered by a fluid actuator 62 via a forked lever 65 while pulley 54 adjusts automatically against a spring 61. The pitch variation is limited by a cam surface 76 which contacts lever 65 and is adjusted via a screwed stud 78 by an adjuster slot 77. A suitable control circuit is illustrated in Fig. 3 (not shown) which derives its power from a transformer driven by the main motor power supply. This circuit includes a timer to determine the predetermined time. The circuit also includes a switch 35 sensing sliver entering the sliver can which also functions as a stop motion in the event of sliver breakage. The process allows a slow initial fiber feed while the produced sliver is being threaded up.

[Class 132 (ii)] Appliances for playing a game comprise a captive ball adapted, when struck from a tee, to travel along a base until arrested and trapped by a screen or curtain, means being actuated as a result of the balls being arrested for indicating the value of the stroke. A golf ball 4 is tethered by a cord to a ring 3a slidable along a rod 2 situated in a longitudinal recess in a base 1. The ball is teed on a sheet 6 of resilient material such as fibreboard and is struck by a golf club towards a screen 7. This screen is mounted on the free arms of two inverted U-shaped springs 8 by means of crossbars 9, 10, of which the lower is fixed to the springs and the upper is slidable thereon to allow the screen to collapse and trap the ball. The springs and screen are rotatable clockwise relatively to the base for packing purposes. Situated at the sides of the base are two similar charts graduated to represent the " holes " of a golf course. An index 24 in the form of a miniature golf ball co-operates with each chart and is advanced by the impact of the ball with the screen to indicate the distance the ball would have travelled if unimpeded. The indexes are carried by endless bands passing around pulleys 23, the pulleys at the front end of the base being rigid with actuating arms 25. These arms co-operate with cranks 20 formed on a cross-rod 19 having a centre crank 18 over which passes a loop 17 in the rod 2 that, at its other end, is attached to the rod 10 of the screen 7 and is provided with a stop 12 for the ring 3a. In playing the game, a player adjusts the actuating arm 25 for his indicator into the path of the associated crank 20 and proceeds to strike the ball into the screen. He repeats this operation until his index reaches a part of the charts that represents a green, whereupon he putts a free ball from a shallow recess 28 into a hole 27 in the base. His opponent then plays in similar manner. In the event of a player overshooting the "green", the crossrod 19 is given an initial partial rotation so that the loop 17 rides freely over the crank 18 during its outward movement and becomes operative on its return, whereby the effective actuating arm is reversely rotated. The initial positions of the cross-rod are controlled by pairs of stops 31 projecting from slides and co-operating alternatively with the cranks 20.
