Title: An electrical control and safety circuit
IPC: F16P3/20
Filed: 1963-12-17
Abstract: 1,066,338. Machinery safety devices. M. VON BUSHE, and T. ALTENBRECHT, [trading as TH. KIESERLING & ALBRECHT]. Dec. 17, 1963 [Feb. 20. 1963]. No. 49865/63. Heading F2J. In a control system for a machine, e.g. a power press or punch, having parallel connected interlocked relays C1-C4, interlocked with a delayed action relay D, controlling series connected contacts Cld, C2c, C3d, C4b in the energization circuit of an electromagnetic valve V which when energized effects operation of the machine, and limit switches E1. E2, actuated by the machine, in the circuits of relays C1-C4, the contacts are opened to stop the machine upon failure of any relay or limit switch. To set up the system for operation, a master switch 5 is closed, energizing a relay C4 to close contacts C4a, C4b and open a contact C4c, and a relay C1 to open contacts C1a-C1d and close a contact Cle. Also a warning lamp h is illuminated and a capacitor K2 is charged. Momentary depression of a key T closes a contact Tb, energizing a relay C3 to close contacts C3a-C3d and open a contact C3e to extinguish the lamp h, and opens a contact Td to de-energize the relay C4 to open the contacts C4a, C4b and close the contact C4c. Operation.-The operator uses both hands to depress push-buttons b1, b2 and hold them until near the end of the working stroke of the machine, opening contacts b1a, b2a and closing contacts b1b, b2b to discharge the capacitor K2 through a relay C2 which closes contacts C2a, C2c and opens a contact C2b, the latter acting to de-energize the relay C1, closing contacts C1a-C1d and opening contact C1e. The closure of the contact C1c energizes the relay C4 to close the contacts C4a, C4b and open the contact C4c. All four contacts controlling the valve V are now closed and the machine is started on its working stroke, near the end of which a cam 2 closes contacts E2a, E2b which respectively complete a holding circuit for the relay C2, allowing push-buttons b1, b2 to be released, and energize the relay D. Before the relay D produces its output impulse, the working stroke ends and cams 1, 2 open the contacts E1, E2a, E2b to de-energize the relays C3, C2, opening contacts C2a, C2c, C3a-C3d and closing contacts C2b, C3e. Contact C2b reenergizes the relay C1 to open contacts C1a- C1d, and close contact Cle. Simultaneously a pulse from the relay D momentarily opens contacts Dc, Dd and closes contacts Da, Db, deenergizing the relay C4 and illuminating the lamp h. On the return stroke, the switch E1  is closed again to re-charge the capacitor K2, while the opening of contacts C1d, C2c, C34 de-energizes valve V to stop the machine. A new cycle is initiated by depressing buttons b1, b2.

Abstract: 1491270 Labelling H KRONSEDER 18 Dec 1975 [20 Dec 1974] 51964/75 Heading B8F Labelling apparatus comprises a rotary label carrier 2 having a plurality of label transfer elements 4 for extracting labels from a magazine 13, a rotary labelling cylinder 7 having a plurality of label receiving elements 10 to which labels are transferred from the carrier 2, means for driving the carrier and cylinder so that the peripheral speed of the elements 4 exceeds that of the elements 10, and grippers 9 on the cylinder for engaging the labels by their leading edges on to the elements 10. In the figure, each element 4 is pivoted by cam mechanism about shaft 3 on carrier 2, so as to roll over the outermost label in the magazine after passing a gluing roller 6. The fingers 9 are operated by cam 8 and followers 18, and the labels are applied to, e.g. bottles by sponge rubber cushions 11. The cylinder and carrier drives are connected by gears 15, 16, and the peripheral spacing of the elements 4, 10 and the relative speeds of rotation are such that at closest approach as shown, the leading end of a label and element 4 register with but are moving faster than an element 10. One or more fingers 9 are within an aperture 21 in the leading end of element 4, and are operated by cam 8 to grip the label on to element 10, causing the label to adopt a stepped formation. In one embodiment, this stepped formation is caused by not closing the gripper on to element 10 until the element 10 is some four degrees past the position of closest approach shown. In another embodiment, the gap between the label leading end and element 10 at the position of closest approach is sufficient to produce the stepped formation. The radially inner face of the trailing end of each gripper is curved.

Abstract: 1279837 Data processing WESTERN ELECTRIC CO Inc 24 Oct 1969 [25 Oct 1968] 52108/69 Heading G4A In a data processor, certain address locations in a memory storing instruction words each contain a group of instruction words, a second instruction word of such a group being decoded during execution of a first instruction word of the group to selectively read-out a further address location without execution of the second instruction word. The locations, read-out in turn to an instruction register, each contain one full-length instruction, or two half-length instructions the second of which may be a NO-OP instruction. A primary decoder responds to the first half of the register to cause execution of the full-length or the first half-length instruction while a secondary decoder detects whether there is a NO-OP instruction in the second half. The next location is then read-out, unless there are two half-length instructions the second of which is not a NO-OP instruction in which case readout of the next location is postponed to permit the second instruction to be gated to the first half of the register and executed first.

Abstract: 1,156,771. Electrophonic musical instruments. ALLEN ORGAN CO. 22 Nov., 1966, No. 52291/66. Heading G5J. In a keyboard electrophonic instrument each key controls a vibrating mechanical switch controlling the output of a corresponding tone generator. As shown depression of a playing key 24 releases a stressed spring 32 carrying a weight 38. Until the key is released, the spring vibrates repeatedly opening and closing contacts 42 and 50. The contacts connect the power supply to the tone generator and give a reiterative effect as in a xylophone, marimba or mandolin. In a modification (Fig. 2, not shown) a spring is carried on each key and carries at its free end, contact members which connect fixed contacts. The contact members which may correspond in size to the note to be sounded can be heard to impact the fixed contacts. The clicking sound produced is similar to that produced when a plectrum contacts the strings of a mandolin. In a further modification, the springs are pivoted by solenoids electrically operated by the keys.

Title: Hydraulically operable dual-circuit brake systems for motor vehicles
Inventor: SCHUPP JAKOB EDMUND
IPC: B60T8/18

Abstract: 1,270,917. Hydraulic dual circuit brake system. GENERAL MOTORS CORP. 5 Nov., 1970 [8 Nov., 1969], No. 52647/70. Heading F2F. In an hydraulically operable dual-circuit motor vehicle brake system, a tandem master cylinder 1 has pistons 4, 5 which control the pressurization in lines 24 and 20 respectively, line 20 being connected to brake cylinders 22 of front wheels 21 and line 24 being connected to brake cylinders 25 of front wheels 22 and to brake cylinders 35 of rear wheels 34 via a brake pressure regulator 30 and a line 33: the pressure regulator 30 has an inlet 31 and an outlet 32 and a branch 36 connects a further inlet 37 of the regulator 30 to the line 20 and the regulator 30 comprises a stepped piston 43 having a passage 62 therethrough communicating an inlet chamber 46 with an outlet chamber 60 which passage 62 is openable and closable by a spring- loaded plunger 54 co-operable with a valve seat 52 to control hydraulic flow to the rear brake cylinder 35. The stepped piston 43 is biased by a spring 67 to the left so that a stem; portion 53 of the plunger 52 abuts an inner face 57 of a closure 58 to hold the valve 52, 54 open but the piston 43 is movable against the bias of spring 67 to close the valve 52, 54 by pressure in the outlet chamber 60. The inlet 37, however, connects with an additional inlet chamber 48 and pressure therein is actuable to move the piston 43 in the some direction as the bias of spring 67. Thus in operation pressure build up in chambers 6 and 7 of the master cylinder 1 is communicated to all the cylinders 22, 25, 35 but if the pressure in the outlet chamber 60 of the regulator 30 rises beyond a predetermined limit the piston 43 is moved to the right to close the valve 52, 54. This predetermined limit is determined by the ratio of areas 75, 76, 77 of the piston 43 and in the event of the circuit 7, 20, 22 failing then the valve 52, 54 closes at a lower value to avoid overbraking of the rear wheels 34 in comparison with the front wheels 21. According to the embodiment of Fig. 4 the regulator 30 also responds to the loading of the vehicle. A doublearmed lever 85 is pivotally connected to an end portion 47 of the piston 43: one arm 86 of the lever 85 is connected by a spring 87 to an extension 88 of the casing 40 of the regulator 30 and the other arm 89 is connected by a linkage 90 to a spindle 91. As the load on the vehicle is increased the spring 87 is extended with consequent increase in load on the piston 43: this permits a greater pressure build-up in the regulator 30 before the valve 52, 54 is closed and consequently higher braking pressure at the rear wheels is achieved when the vehicle is loaded.
