Title: Improvements in or relating to the reproduction of recorded sounds
IPC: G11B3/00
Filed: 1926-12-10
Abstract: 282,413. Kuchenmeister, H. J. Dec. 15, 1926, [Convention date]. Optical apparatus. -Relates to the reproduction of recorded sound by the method in which two or more similar film records are used simultaneously to produce an improved acoustic effect by causing repetition of the sound reproduction with an interval of the order of a fraction of a second between the same individual sounds. According to the invention, in order that the time interval mav be varied, to suit the listener, the rollers by which the film records are moved synchronously are so arranged that their relative angular positions may be adjusted as desired. As shown, the films 23, 24, bearing similar sound records, are driven by rollers 26, 27, which are secured to shafts 38, 39 having a common driving mechanism 40, the shafts being coupled by a. clutch 25, 25<1>. The difference in phase in the reproduction of the records, represented by the distance y, may be altered as desired by disconnecting the clutch members, by hand or otherwise, and re-engaging them after rotating the parts relatively to each other.

Filed: 1962-09-11
Abstract: 947,970. Screw jacks. SKYLUX Ltd. Sept. 11, 1962, No. 34687/62. Heading B8J. In a jack capable of instantaneous extension and retraction, the wall of a housing 1 has two diametrically opposed longitudinal slots 3, each having three offset slots 4. Two pins 6, 7 movable along the slots 3 and selectively engageable with the slots 4 project from sides of a nut 5, pin 6 being readily visible by an operator. The nut 5 engages a screw-threaded portion 8 of a load-bearing spindle 9 extending through the housing 1 and is provided with a ground pad 11 and hand wheel 12. A compression spring 13 urges the nut 5 upwardly. Assuming that the jack has been attached to a mobile structure by a bracket 2, and that the spindle 9 is retracted in the housing 1, downward pressure on the hand wheel 12 causes the pins 6, 7 to ride along the associated inclined slots 4 into the slots 3 so that the spindle 9 may be fully extended instantaneously until the pins abut the lower ends of the slots 3. When the hand wheel is turned to elevate the structure the pins are forced into locking engagement with the lowermost slots 4 and continued rotation of the hand wheel will elevate the structure. The jack may be instantaneously retracted by turning the hand wheel slightly in the opposite direction to that for extension, the pins thus being disengaged from the slots 4 and being free to move in the slots 3 to the retracted position under influence of the spring 13. The hand wheel may be turned to elevate the structure with the nut 5 locked in the intermediate or uppermost slots 4.

Abstract: 757,971. Toy vehicles. ERHARD, K., and JACOBOWITZ, M., [trading as TIPP & CO.]. Dec. 1, 1954 [Dec. 1, 1953], No. 34846/54. Class 132(3) The driving mechanism of a toy vehicle also actuates a supplementary device such as a tipping body, or, when the vehicle is a fire engine, a fire escape, means operated by the said mechanism also being provided for controlling the steering of the vehicle and the drive to the road wheels. In Fig. 1. drive from a spring (not shown), to the rear axle 16 of a toy tipping lorry is by means of a pinion 15, crown wheel 14 and toothed spindle 11, the latter being driven from a main gear 5 on which are provided projections 7, 36. The projections 7, periodically engage a, lever 9, which at one end carries the bearing portion 10 of the spindle 11. the portion 1.0 being movable in a slot 12 but normally urged to the position shown in Fig. 2 by a spring 13. The projections 36 are adapted to engage a stud 33 provided on a disc 34 pivoted on a shaft 35. the stud depending through an arcuate slot 32 formed in a chassis member 31. The disc 34 also has an upwardly projecting stud 33<SP>1</SP> which periodically engages a stirrup 38 the ends of which are pivoted in the tipping body 41 at 40. During rotation of the main gear 5, when the spring unwinds, each projection 7 in turn causes the bearing portion 10 to move along the slot 12, the crown wheel 14 being urged out of the horizontal and those teeth meshing with the pinion 15 being forced against the pinion thus causing a braking action on the driving wheels 17; simultaneous disengagement of the drive from the main gear 5 to the spindle 11 is also caused. As the gear 5 cotinues to revolve, one of the projections 36 causes the stud 33<SP>1</SP> and disc 34 to partially rotate and the body 41 to tip when stud 33<SP>1</SP> engages the stirrup 38. The stud 33 eventually clears the projection 36, the body 41 dropping to its normal position and causing the disc 34 to rotate hack again. The toy is steered automatically by the engagement of a bell-crank lever 20 with the projections 7, a 'rod 22 connected to the lever and to a front axle member 23 causing the front wheels to be turned for steering. A modification in the form of a fire engine. Figs. 11-13 (not shown), includes a fire escape mechanism. ladder sections being caused to extend when the drive to the vehicle wheels is . disengaged Electric motor drive is specified.
