Title: Improvements in or relating to registering devices
Inventor: HOFGAARD ROLF
IPC: H04Q1/34
Filed: 1946-05-20
Abstract: 618,257. Data-storing devices. HOFGAARD, R. May 20, 1946, No. 15238. [Class 106 (i)] A device for storing and transmitting impulses for use in connection with calculating machines &c. comprises a number of elongated plates (13) provided with movable contact pins (17) which, when the plates are moved towards adjustable abutments (28), are selectively displaced. When the plates are moved in the opposite direction the displaced pins (17) engage contacts (47) and close electrical circuits and, upon further movement toward the contacts, the pins are re-set to their initial positions with respect to the plates (13). The pins 17' are grouped, e.g. in fours, and their displacements arranged according to a code, whereby multidenominational numbers, letters or other signs can be represented. The required plate or register is selected by means of a stack of platelike members 32 ... 38 having castellations c along one edge coded in such a way that, for each of a number of possible arrangements of the members, a channel is formed opposite the edge of one of the plates 13, allowing the latter to be spring-urged to the right, whereby hooks 24, 25 engage with corresponding grooves 26, 27 in supporting rails 9, 10, which, by means of rotating complementary cams 5, 6, 7, 8, lift the selected plate 13 towards the abutments 28. The abutments 28 have uniform castellations along their lower edges, and each may be positioned either (a) so that the pins 17 pass ineffectively between castellations during the upward movement or (b) so that a pin 17 is engaged by a tooth of the abutment during the upward movement and is displaced relative to its plate 13. A solenoid 29 is associated with each of the abutments 28 and, when energized, releases a catch to allow its associated abutment to be moved to operative position by spring means. The displaced abutments are restored by cam means. A bevel wheel 2 on the main shaft 1 has teeth on one-third of its periphery and, during this portion of its revolution drives a shaft 41 which has cam-shaped cross-sections where it passes through the members 32 ... 38 and a support 40. In this way the support 40 moves relative to the members 32 ... 38 to push the previously selected plate 13 back to the left after a data-storing or reading-out operation. The members 32 ... 38 are relatively displaced to select a particular plate 13 by solenoid and spring means similar to those used for the abutments 28. The pins 17 in each plate 13 are frictionally held by a flat spring woven between them along the slot 19. Specification 614,008 is referred to.

Filed: 1967-04-04
Abstract: 1,176,735. Control of A.C. motors. TOKYO KEIKI SEIZOSHO CO. Ltd. 4 April, 1967, No. 15288/67. Heading H2J. [Also in Division G1] A starter system for a gyrocompass 1 includes a time switch 4 which enables the gyrocompass to be connected to a power supply 2 to start the gyrocompass at a pre-set time. The 50 c/s. output from the supply 2 is converted to 200-400 c/s. by a rectifier 6 and an inverter 7. In the manual position of the switch 3, when the contact f, is connected to the contact d, a solenoid 51 is energized and its switch 5 connects the power supply to the gyrocompass. For automatic operation, the switch 3 is set so that contacts g and d are connected. At the end of an interval of time, pre-set on the time switch 4, contacts a and c of sets of contacts 41 and 42 are connected. The gyroscompass is therefore connected to the power supply and simultaneously the contacts c and a of a relay 8 are connected. The relay 8 prevents an alarm 11 sounding unless the power supply to the gyroscompass fails in which event the contacts c and b of the relay 8 are connected so that the alarm is connected to a power supply 10 through a changeover switch 9. The second position of the switch 9 switches off the alarm and in this position the alarm will sound again when the power supply is eventually restored.

Title: Improvements relating to starting mechanisms for internal combustion engines
IPC: F02N11/12
Filed: 1935-05-25
Abstract: 457,336. Starting prime movers. C.A.V.- BOSCH, Ltd., PARSONS, S. F. H., and GLASER, W. H., Warple Way, Acton, London. May 25, 1935, No. 15317. [Class 38 (iv)] The engine of a motor vehicle may be started from an external source of electrical energy as an alternative to normal battery starting, an additional switch serving firstly to effect a temporary connection with the battery to engage the toothed starting pinion and secondly to supply current from the external source for starting. For normal battery starting, switch e is closed so that current flows through winding f whereby switch g is moved to its first position thus closing a circuit through battery c, series motor a, b, and resistance d. As soon as the pinion is moved into engagement with the toothed wheel on the engine, a detent holding switch g is tripped so that the switch may move into its final position in which the resistance d is short circuited and the engine is started. The additional switch h first leaves contacts i and engages contacts j so that the battery circuit is completed through resistance d to engage the pinion but not through switch e; and secondly leaves contacts and engages contacts k so that power supplied from the external source may turn the engine.

Title: Improvements in or relating to stop-motions for nap-raising machines and other machines for finishing or otherwise dealing with textile and other fabrics
IPC: D06C29/00
Filed: 1919-06-23
Abstract: 145,258. Cansell, W. E. June 23, 1919. Stop-motions.-In stop-motions for use in napraising and other machines for dealing with fabrics wherein two engaging members are normally driven at the same speed from a power-driven part of the machine and by the passage of the fabric over a roller respectively, one of the members being moved axially to stop the machine when the members are driven at different speeds, the means for moving the belt fork or equivalent part of the stopping position is actuated by a power-driven part of the machine. As shown in Fig. 1, two pieces of fabric pass over rollers a, a<1> to a power-driven roll l. The roller a is fast on a shaft b which carries a splined sleeve c having a clutch member f normally in engagement with a toothed wheel g loose on the shaft b and meshing with a wheel h loose on a sleeve j on the shaft k of the roll l. If the fabric passing over the roller a<1> breaks or tears out, this roller ceases to rotate and a slidable nut d carried thereby engages a screwed part c<2> of the sleeve c, thus disengaging the clutch member f from the wheel g, which ceases to drive the wheel h. The continued rotation of the sleeve j causes an internal thread on the wheel h to engage a threaded portion j<2> of the sleeve, and the wheel is forced into engagement with a normally idle disk o adapted to drive a pulley u<1> connected with means to operate the belt fork. If the fabric passing over the roller a tears, this roller ceases to rotate and the wheel g is stopped, the belt fork being operated as before. In a modification, a number of pieces of fabric pass over a roller a, Fig. 4, fast on a shaft b carrying a toothed wheel g<1> in gear with a wheel k screwed on a sleeve fast on the shaft k of the roll l. A band brake q on the shaft b is adjusted so that if one or more of the pieces of fabric break or tear out, the roller a ceases to rotate and the wheel h is forced into engagement with the disk o to stop the machine. The disk engages the pulley u<1> which is connected by a belt u with a pulley u<2> having a toothed quadrant v<1> in engagement with a rack v<2> carrying the belt fork v<4>. When the belt is moved to the loose pulley v<7>, a rod x pivoted to the rack moves to the right and its upper end engages the pivoted shaft w of the pulley u<1> to move it, against the action of a spring, out of engagement with the disk o. According to the Provisional Specification, the belt fork may be operated by chain gearing, and a brake may be applied to the driving- shaft when the stop-motion acts.
