Abstract: 762,185. Hardening axle bushings. JAEGER GES., G. & J. Sept. 11, 1953 [April 30, 1953], No. 25216/53. Class 72 In a process for surface-hardening internal bearing surfaces of axle bushings made of steel having section (s) and/or surface(s) which are not to be hardened the whole workpiece is heated at the same time to hardening temperature and is then chilled with a cooling medium at the internal surfaces to be hardened, those section(s) and/or surface(s) which are not to be hardened being screened from the effects of the cooling medium. In the embodiment shown the bushing 1, after having been heated to hardening temperature, is fitted on to a collar 2, held by a plunger 3 and radially clamped by cheeks 6, 7. The cooling medium, e.g. water, aqueous solutions, or emulsions, is sprayed on to the inside of the bushing from rotatable sprinkler 8, those parts of the bushing which are not to be hardened being screened from impingement of the cooling medium by the collar 2 and covering ring 9. Where the mass of material is greater, as at 10, a cooling medium is applied from the outside in order to achieve a uniform distribution of heat despite the non-uniform cross-section. Various compositions of steels suitable for the process are given

Title: Improvements in or relating to sliding doors
IPC: E05D15/10
Filed: 1948-09-29
Abstract: 649.880. Sliding doors. KING, Ltd., G. W., and BURROWS, A. T. C. Sept. 29, 1948, No. 25379. [Class 20(iii)] A sliding door which moves back and forth in a predetermined path into open and closed positions has means to impart a vertical movement to the door subsequent to its arrival in the closed position and a reverse vertical movement prior to its movement therefrom, and such vertical movement is utilized to effect operation of pivoted latch or hook members 24, 25 disposed at two opposed lateral edges of the door and adapted to co-operate with fixed brackets 27 at either side of the door opening according to the direction of the vertical movement so as to move the door inwardly against or outwardly from sealing means 28 around the opening. The door 10 is suspended from two trolleys 11, one or both of which may be driven, moveable on track 12. The lifting unit comprises a motor 13 coupled to a threaded rod 14 rotatably journalled in the door structure on a vertical or substantially vertical axis, and a threaded member 15 on the rod 14 normally restrained against rotation, and moved vertically when the rod rotates. Cables 16 on the member 15 pass around pulleys 17 .freely mounted on the door, and then around sheaves 18 on trolleys 11, and the ends are adjustably coupled together by a turnbuckle 19. Pulleys 17 are equally spaced from the centre, and when the member 15 is moved by rotation of rod 14 the door is moved vertically accordingly. The motor 13 is operated automatically to raise or lower the door at the closed position. A rod 23 disposed adjacent and parallel to each lateral edge of the door has a plurality of spaced hook elements 24 and is connected to the door by links 25. The bars 23 are slightly offset with respect to each other, and preferably have rollers 26 at the lower end, and do not move vertically with the door. The hooks 24 engage in the brackets 27 on the door opening as the door moves to closed position. As the door is moved vertically it will, by the action of links 25, move inwardly or outwardly and co-operate with sealing elements 28.

Title: Data punching machines
Inventor: WESSON NOEL ROBERT
IPC: G06K5/02
Filed: 1965-06-16
Abstract: 1,086,645. Selective punching machines. ENGLISH ELECTRIC COMPUTERS Ltd. Sept. 13, 1966 [June 16, 1965], No. 25492/65. Heading B4B. A machine for punching a tape 20 with boles representative of informarion to be stored comprises a punch 16 operable by a hammer 10 reciprocally driven by a wheel 12 and connecting rod 11, the hammer being moved into alignment with the punch by a reset stop 13 and maintained in such alignment, against the action of a spring 15, when the coil 31 of an electromagnet 21 is energized, the electromagnet being de-energized immediately a hole has been punched in the tape, and monitoring means responsive to the magnetic condition of the electromagnet for providing an output signal indicative that the hammer has been moved out of engagement with the punch by a knock-off stop 14 at a time when a substantial proportion of the energization voltage still exists across the coil 31. The circuit, Fig. 2, comprises the coil 31, resistors 30, 35 and a switch 33 and a monitoring circuit comprising a capacitor 36, resistors 35, 37, 39, 45, diodes 41, 43, a transistor 38 and a logic circuit gate 48. When the coil 31 is de-energized by opening the switch 33, the induced back e.m.f. decays as the coil 31 discharges through the circuit comprising the resistors 30, 35. Superposed on the voltagetime curve, which is basically exponential, are two spikes the first of which is produced when the switch 33 is opened and the second of which when the hammer is forced out of engagement with the electromagnet 21 by the stop 14. The capacitor 36 acts to differentiate the voltage across the coil 31 and allows substantial current to flow only when the two spikes are produced. The corresponding pulse signals produced by the transistor 38 are passed to the gate 48 which receives a timing reference signal each time a hole is required to be punched in the tape. Each timing signal is initiated at the instant of time when, during the associated downward stroke of the hammer, the hammer should normally have been forced by the stop 14 out of engagement with the punch. If the punch operates correctly, the timing signal appears at the gate 48 simultaneously with the pulse output signal corresponding to the second spike of the voltage-time curve. If such coincidence does not occur, the gate 48 produces an output signal indicative of faulty operation of-the punch. In a variation, the magnetic condition of the electromagnet is sensed by the use of a search coil additional to the coil 31 and the capacitor 36 may be omitted. In another variation, the capacitor 36 is replaced by a saturable transformer. If the electromagnet 21 is of sufficient power, the stop 13 may be omitted.
