Filed: 1943-07-22
Abstract: 569,626. Clay pigeons. BOYCE, R. D. July 22, 1943, No. 11940: [Class 132 (i)] [Also in Group V] A clay pigeon has at its lip a sheet-metal member b, a portion of which constitutes a circumferential wall and a portion of which is embedded in the composition so that the body a of the clay pigeon and said sheet-metal member constitute an integral structure. The clay pigeon is made by moulding a mixture of pitch and either chalk or cement. The member b is placed in the female die k and the correct amount of the mixture added. The male die m is lowered and the mixture penetrates perforations h and notches in the member b, and fills out the space n to compensate for the reduction in weight caused by the use of the metal rim. To prevent the mixture squeezing out at the edge, the male die contacts the shoulder d which rests directly on the female die ; additionally those parts of the dies contacting the shoulder d and the bead f may be spring-pressed so as to effect a sealing contact before the full pressure is applied.

Title: Improvements in or relating to indicator marking system for dictating machines
IPC: G11B25/06
Filed: 1954-05-03
Abstract: 748,203. Dictating machines. DICTAPHONE CORPORATION. May 3, 1954 [May 5, 1953], No. 12774/54. Class 40(2) In a dictating machine, automatic marking apparatus is provided for applying distinctive marks on a pad of slips to indicate instructions, "end of letter" indications, and the like. The embodiment described shows the pad 12 of slips carried on a tray 18 which, when an indication mark is to be made, is lifted from the normal position, as shown in full lines in Fig. 5, to one of two higher positions, so that a marker roller 93 makes a line on the pad 12, the length of the mark being related to the nature of the instruction, and the longitudinal position being related to the position of the transducer 24, Fig. 1. The short mark may, for instance, indicate that a correction is to be made, while a long mark may indicate the end of a letter. The lifting of the tray is effected by means of electromagnets 30, 32. The magnet 30 is a rotatory one and when its circuit is closed by a press switch 106, the resulting rotatory motion is restricted by an arm 38, Fig. 4, which intercepts an arm 40 movable with the tray 18, and thus causes only a short mark to be made. Current passes through the magnet 30 only of sufficient duration to discharge a condenser 126, after which the tray 18 is returned to its normal position under the influence of a spring 80. If a long mark is to be made a press switch 104 is moved downwardly to discharge a condenser 127 through magnet 32 which draws the arm 38, forming part of a bellcrank 59, out of the path of the arm 40. The operation of this magnet closes ccntacts 42, 44 in the circuit of magnet 30, whereby a long mark is made on the pad 12. Specification 742,490 [Group XXXIX] is referred to.

Title: Improvements in or relating to variable speed gearing
IPC: F16H63/30
Filed: 1932-05-05
Abstract: 405,664. Controlling change - speed gearing. WILSON, A. G., 23, Queen Anne's Gate, London. May 5, 1932, No. 13034. [Class 80 (ii).] Relates to means for braking reaction drums in change-speed epicyclic gearing especially of the Wilson type such as described in Specifications 164,042, 312,128, and 328,660, [all in Class 80 (ii), Gearing, Variable-speed &c.], and as applied to vehicles. A reaction drum, or each drum, 1 has teeth 2 upon it adapted to be engaged by teeth 4 upon a non-rotary similarly-toothed stationing device 3 and these teeth are synchronized prior to engagement by braking. The stationing device 3 is carried by an actuating member 11 which extends through a shot 12 in a fixed casing 13. Integral with the drum 1 is the male member 7 of a cone brake the female member 8 of which is formed upon a ring 9 surrounding the drum 1 and outside the stationing ring 3. In a form shown in Fig. 1, the ring 9 is attached to the ring 3 by a feathered connection 14, 15 and by a spring- pressed ball catch 10. To stop the drum 1, the member 11 is thrust to the left. This first brings the brake 7, 8 into action so slowing down the drum. Continued movement causes the ball catch 10 to slip so that the teeth 4 of the ring 3 can pass on into mesh with the teeth 2 of the drum thereby holding the drum positively against rotation. In Figs. 2 and 3 are shown means for preventing the advance of the ring 3 as long as the drum 1 is rotating. When the non-rotary brake cone 8 is advanced into engagement with the cone 7 on the drum, the cone 8 is angularly displaced as far as permitted by slots 17 and through pins 14. This brings teeth 16 on the ring 9 in front of the teeth 4 on the ring 3 so as to prevent passage of the teeth 4. The teeth 16 remain in this obstructing position as long as the drum 1 rotates. When the drum 1 stops, springs 15, Fig. 2, displace the ring 9 back through the length of the slots 17 to the position of Fig. 3 when the teeth 16 are out of the path of the teeth 4 which may now be advanced into engagement with the drum teeth 2 so as to lock the drum positively. Specifications 402,794 and 405,960 also are referred to.
