Abstract: 583,239. Control of two motors. B.S.A. TOOLS, Ltd., and OGILVIE, W. June 17, 1944, No. 11575. [Class 38 (iii)] [Also in Group XXII] In a turret lathe comprising an electric motor operating through gearing to feed the turret slide to allow a tool to operate on a work-piece and a second electric motor adapted at predetermined times to move the turret towards and away from a work-piece at a higher speed notwithstanding continued operation of the first mentioned motor, the second motor is momentarily reversed when it is switched off in order to effect instant stopping of the higher speed drive. The main motor 4 drives the machine spindle 16, Fig. 2, through gearing 8, 10, 14, and also drives the cam drum 54 through additional gears 24, 28, 30, 32, 36, shaft 38, worm 5Q, and worm wheel 52. An additional high speed motor 62 is geared to the other end of the shaft 38, through worm gear 56, 58. The worm wheels 36 and 56 both drive through one-way clutches. In operation, the motor 4 is run continuously. For feeding the turret slide rapidly up to the work the motor 62 is operated and drives the turret operating cam drum 54 at a relatively high speed, the one-way clutch of the gear 36 allowing the drive from the motor 4 to be overrun. As the tool reaches the work, a dog on another cam on the shaft of the drum 54, operates a switch to cut out the motor 62 and the in feed of the tool then continues at a slower speed driven by the motor 4. As the cam 54 begins to retract the tool, another dog operates the switch gear to set the motor 62 running to move the turret rapidly back to its starting position. In order to ensure instant stopping of the high speed drive, the motor 62 is momentarily reversed by another switch when the circuit for the forward drive is broken.

Title: Improvements in or relating to fluid pressure control systems
IPC: G05D16/20
Filed: 1953-04-27
Abstract: 775,756. Automatic pressure control systems. MERCIER, J. April 9, 1954 [April 27, 1953], No. 11604/53.. Class 38 (4). [Also in Group XXXVII] In a system for maintaining fluid pressure within predetermined limits, a snap-action micro contact switch or switches, responsive to the fluid pressure, is associated with two external springs and switches on or off electrically-driven pumps or compressors supplying the fluid. In Fig. 1 fluid pressure acting on a diaphragm 11 moves a piston 2 in opposition to a spring 10 to operate the button 23 of a snapaction micro contact switch 12 through a rod 22 and a leaf-spring 24. The limited longitudinal movement of piston 2 in cylinder 1 prevents excessive deflection of diaphragm 11. The stiffness of spring 24 determines the switch differential. In a modification, Fig. 4, in which rod 22 operates switch button 23 through a pivoted lever 30 and a leaf-spring 24, button 23 is only operated when the end of screw 31 abuts spring 24 but not released until the end of lever 30 engages the turned over end of spring 24. In other modifications (not shown) rod 22 operates two micro contact switches in succession, one at the lower pressure limit and the other at the upper. In Fig. 6, fluid pressure acting on a diaphragm 62 moves a piston 33, having limited movement, to apply a force through a knife-edged strut 39 to a lever 38 to which an opposing force is also applied by a spring 41. Lever 38, which is pivoted at 43 and balanced against shock at 44, operates a microcontact switch 46 through a spring 50 and lever 49 at the upper pressure limit, and operates a micro contact switch 45 through a spring 56 at the lower pressure limit. In this arrangement springs 50 and 56 serve to determine the switch differentials. In Fig. 7 a diaphragm-operated piston 70, having limited movement, acts in opposition to springs 72, 73 in succession, to operate a micro contact switch button 76 through a spring 74. A large differential is obtained in this case by virtue of spring 74 and the fact that spring 73 becomes effective after spring 72.

Abstract: 165,994. Crowther, H. L., and Mc- Dougald, L. A.. Airey, H. Morris-, and Irving, G. A. April 27, 1920. Modulating systems and apparatus.-In a transmission system, the power valve is (a) continuously excited by a separate high-frequency source, and (b) the potential of the grid of the power valve is varied at audible frequency by means of a microphone for telephony, or by a low-frequency oscillating valve or other source for telegraphy. As shown in Fig. 1, the plate of the power valve 6 is fed from a high-tension supply 8, whilst the grid is coupled at 11 to a separate oscillating- valve circuit 10. The audible signal frequency is superposed on the grid circuit by a microphone 12 which is coupled at 13 to the grid-filament circuit of valve 14, the anode-filament circuit of which constitutes the grid leak-resistance of the power valve 6. In alternative forms, the audible signal frequency is superposed on the grid of the power valve either by inserting the microphone transformer directly in the grid circuit of the power valve, or by placing the microphone transformer in the grid circuit of an auxiliary valve, such as 14, Fig. 1, and coupling the plate circuit of this valve directly to the grid circuit of the power valve.
