Abstract: 747,133. Toothed wheels. DANSK SPARE-SELSKAB. March 2, 1954 [Aug. 5, 1953], No. 6130/54. Class 80(1) A method of detachably securing a number of studs to a plate is applied to a pin wheel such as is employed in a slot machine wherein it is required that the number of studs 4 mounted on a disc 1 to form the pin wheel may be readily changed. Each stud has a head 5 and a recess 7 so that after inserting the studs through holes in the disc a spring ring 9 may be forced into the position shown to engage all the recesses 7 and thus lock the studs to the disc. Alternatively, the ring may encircle all the studs. Each stud has a double conical collar 8 so, that individual studs may be pressed in or out of the disc. The shorter studs shown - in Fig. 1 serve only to locate the ring 9 and are inoperative as teeth of the pin wheel. Specification 474,968 [Group XVIII] is referred to.

Filed: 1943-04-22
Abstract: 563,202. Kinematograph apparatus. BOLSEY, J. April 22, 1943, No. 6514. [Class 97 (i)] Fade-out and fade-in effects are produced by a light - reducing member, such as a neutral grey wedge, or by masking plates, movable across the light beam, in one direction, by hand, and, in the opposite direction, by a spring which is stressed during the hand movement; means regulating the speed of the member and means controlling the film-feeding mechanism are associated with the device. As shown, the wedge 1 covers part of an aperture in a carrier 2 reciprocable vertically across the gate aperture 8. Upward movement, to produce fadeout, is effected by a hand-operated lever 13, and a rack 19 on the carrier then, through a pinion 201 and gear 20, stresses a spring 21 ; a spring-pressed button 34 retains the lever 13 in its extreme position shown in broken lines. Speed regularization is effected by. a ratchetwheel 27, pawl 28 and rotarily adjustable eccentric stop 30, or by other means described. A disc 37 driven by the film-feeding mechanism carries a pin 39 engageable by a lever 40 to stop the feed ; the lever 13 has a projection 47 which engages the lever 40 to move it to. stop position against the action of a spring 43 as the lever 13 is approaching the broken line position. For fade-in, the lever 40 is turned by a trigger 44 to free the pin 39, the lever being then held by a spring-pressed button 45. Engagement between the lever 40 and projection 47 forces the lever 13 over the button 34 and permits the spring 21 to lower the wedge 1. Modifications are described in which the spring 21 is replaced by a helical spring directly secured to the carrier 2 and stressed as the carrier moves upwards, or in which the wedge is replaced by two masking plates opening from the centre of the light aperture or closing towards it. In other modifications, the wedge is of annular form or is replaced by an iris diaphragm.
