Patent GB-658703-A (GB)
Title: Relay
IPC: H01H51/08
Filed: 1949-05-02
Abstract: 658,703. Electromagnetic relays. AUTOMATIC ELECTRIC LABORATORIES, Inc. May 2, 1949, No. 11669. Convention date, June 2, 1948. [Class 38(v)] Contacts 25 of a relay are operated into their other position at each de-energization of the relay winding. No movement of contacts occurs at energization of the winding. Another set of contacts, Fig. 3, (not shown), may be operated in the normal way by the same armature 23. When the relay is energized the armature 23, pivoted at 14 is attracted to the core 10 and a screw 45 moves a sliding member 41 to the right against a return spring 46, a tooth 65 on the member 41 moving above an upturned edge 52 of a vertically-moving contact-operating slider 44 and locking this against upward movement. Simultaneously an inclined surface 55 causes a bell-crank lever 42 to move about its pivot 50 until a lever 43 pivoted to the slider 44 at 57 moves down to latch it at 56. During the above movement of 42, a leaf spring 51 pressing up on the slider 44 is strained. On de-energization, the armature and slider 41 move back, unlocking the slider 44 which moves up to actuate the contact springs 25. Upon the next energization the tooth 65 on the member 41 moves below the edge 52 locking the slider 44 in its upper position while the left hand end of lever 43 is engaged by projection 67 to unlatch lever 42, and on the next de-energization the parts return to their original position.

Title: Improvements in wireless transmission systems
IPC: H04B14/00
Filed: 1932-04-23
Abstract: 400,273. Wireless signalling. WALTON, G. W., 2, Dean Street, London. April 23, 1932, No. 11724. [Class 40 (v).] Two components of the same carrier-wave, phase-displaced by 90‹, are radiated simultaneously from separate aerials, after being modulated by signal currents in phase-opposition. For reception it is necessary to supply a local oscillation of the same frequency but de-phased from the incoming carrier so that the signals cause minimum interference in any normal type of receiver. In transmission, Fig. 1, carrier energy from a source 1 is applied in push-pull to two valves 3, 4 having phaseadjusting impedances 20, 21 so that the currents in the two aerials 9, 10 are 90‹ out of phase. Signal energy is fed to the modulating valves 13, 14 in push-pull and is combined with two carrier components in phase opposition. In reception, Fig. 2, an auxiliary valve 35 feeds back to the incoming carrier an out-of-phase component through a coil 37, the phasedisplacement being adjusted by the condenser 34 and resistance 36. According to the Provisional Specification reception is possible on a normal type of set having a low-loss tuned circuit ; or on a, superheterodyne or a receiver in sustained oscillation.

Title: Improvements in or relating to thermal switching devices
IPC: H01H37/46
Filed: 1943-07-24
Abstract: 567,123. Temperature - responsive actuating-elements. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and FRYDMAN, E. July 24, 1943, No. 12065. [Class 64 (ii)] [Also in Group XXXVII] A thermallyresponsive member for effecting a switching or signalling operation at a predetermined temperature is composed of loaded ebonite which has been compressed in one direction. This material is stable at temperatures below 120‹F. but at 180‹-200‹ F. it resumes substantially its original dimensions. In the application to a " heat coil for protecting telegraph and telephone exchange apparatus against prolonged line currents of damaging amount, but too low to operate the fuse, the incoming line conductor terminates in a contact spring 10 which clamps a pair of carbon blocks 11, 12 against an earthed plate 13 in known manner to protect against a high line voltage. The heat coil 14 is clipped between springs 10, 17 and 15. Spring 16 connects to the exchange apparatus. The coil winding 21 is mounted on an insulating pin 22 and surrounded by a compressed ebonite tube 23. Metal caps 24, 25 connect the coil winding to springs 10, 15 and an insulating bush 26 isolates spring 17. Expansion of tube 23 following excessive current in the coil moves spring 17 into contact with earthed spring 10 and then spring 15 away from cap 25,.so that the incoming line is earthed and the exchange apparatus isolated. Replacement of the tube 23 is required. The material is also applicable to the detection of undue temperature rise in windings or bearings, or in ambient temperature, also to thermostat relays in telephone systems.

Title: Electric control device and its application to machine-tool control
IPC: B23Q35/122
Filed: 1952-05-14
Abstract: 716,455. Motor control systems. VALLIERE, M. DE. May 14, 1952. No. 12253/52. Class 38(3) [Also in Group XXXVIII] An electro motor driving, e.g. the feeler and cutter of a copying lathe, has its armature separately-excited from a D.C. source and its field fed with D.C. which is reversed when a control contact, e.g. a feeler contact, closes. As shown, Fig. 1. the motor armature 1 is energized separately by a D.C. source 3 which may be rectified A.C. With the contact 18 open the triode 10 is blocked by the biasing battery 16, and the portion 5 only of the motor field winding is fed with D.C. supplied through the rectifier bridge 6, to drive the motor in the forward direction to close the contact 18. Cathode potential is thereby applied to the triode so that it conducts. The consequential plate current flow through the portion 7 of the motor field winding opposes and overrides the effect of the winding 5 so reversing the motor 1 to open the contact 18. As the contact 18 opens the motor is again reversed. The motor thus oscillates and keeps the contact 18 in substantially continuous engagement with its counter contact 19. In another embodiment, Fig. 6, for a copying lathe when the feeler 49 engages the pattern it applies cathode potential to the grid of triode 48 which conducts and energizes the field 47 to drive the motor 41 in the sense which retracts the feeler from the pattern. At the same time the triode 51 is cut off by the bias caused by the potential drop across resistor 50. When the feeler disengages the pattern the tube 48 is biased to cut off by the battery 59 and triode 51 conducts to energize the motor field in the opposite sense to reverse the motor. The motor thus oscillates as before, the amplitude of the oscillations being controlled by manually adjusting the pressure between the plates of a slipping clutch Fig 7 (not shown) driven by the motor 41 in parallel with the drive to the feeler and cutter.

Filed: 1957-04-15
Abstract: 824,995. Boiler feed water and hot water supply systems. SATZGER, E. April 15, 1957 [April 18, 1956], No. 12269/57. Classes 64(1) and 123(2) The condensate from a low pressure steam heating installation in a dieseldriven railroad car is fed to a closed condensate container and is forced therefrom by intermittently supplied compressed air indirectly to the locomotive collecting tank from which water is fed to the boiler of the locomotive attached to the car. The installation comprises radiators 2, 2, Figs. 1 and 2, supplied from a steam line 1, the radiators discharging condensate through a line 5 and a control valve 6 into a closed condensate container 7 which receives compressed air through an air line 11 from the outlet of the control valve 8 of an air brake cylinder 9. The air line 11 is connected to the control valve 6 which has fitted therein a non-return valve 13, Fig. 3, kept open by a weight 14, the non- return valve closing the outlet 12 of the condensate line 5 when the compressed air flows into the container 7. To ensure that no back pressure will act on the condensate line 5 a vent 15 leading to an outlet pipe 16 is provided which also serves as an outlet when excessive condensate is formed. The compressed air forces condensate from the container 7 through a feed line 17 into the service water container 19 of the toilet installation of the car. The service water container 19 (supplying warm water for washing) being tightly sealed, condensate therefrom is forced through a feed line 21 to a condensate collecting line 23 connected by means of shut-off valves 24 24a, couplings 25, 25a and a coupling hose 26 to the condensate collecting line 23a of the next car, the collecting lines eventually leading to the feedwater collecting tank of the locomotive. The line 23 and the coupling hose 26 are arranged so that condensate will not remain therein but will flow back to the service water container 19. The opening 22 of the feed line 21 is spaced from the bottom of the service water container 19 so that water up to the level 27<SP>1</SP> will always be available for toilet use. In a modification, the feed line 17 is connected direct to the condensate collecting line 23, the container 19 being omitted, and in a further modification, in which the heating installation comprises steam heated radiators and condensate heated radiators, the container 7 is dispensed with, its place being taken by the service water container 19.
