Title: Electrical switching devices relays and systems incorporating same
IPC: H01H61/01
Filed: 1974-04-16
Abstract: 1468404 Thermal relays TEXAS INSTRUMENTS Inc 16 April 1974 [16 April 1973] 16680/74 Heading H1N [Also in Division H2] An electrical relay comprises a wire 32 secured between a support member 12 carrying stationary contacts 18 and a control member 22 carrying movable contacts 24, the wire 32 being made of an alloy which shortens in length and increases its modulus of elasticity when heated above a transition temperature by passing an electrical current therethrough from a power input of less than 2 watts whereby the control member 22 moves from one switching position to another. In one embodiment, a nickeltitanium wire 32 passes from a base 12 over a cap member 26 which bears against a bridging contact arm 22 biased upwardly by a spring 20 which applies a deforming stress to the wire 32 whereby its length is increased. When a current is passed through the wire 32 from a source (38) (Fig. 2, not shown), e.g. an integrated circuit device, via an impedance matching transformer 40 to cause the wire 32 to be heated above its transistion temperature, the length of the wire 32 shortens and its modulus of elasticity increases, whereupon the bridging contact arm 22 is moved against the bias of the spring 20 to cause the contacts 18, 24 to engage. When the wire 32 cools, it is increased in length by the spring 20 whereby the contact arm 22 returns to an open circuit position. The spacing between the contacts 18, 24 is adjustable by a bolt 28. In another embodiment, Fig. 4, the nickeltitanium wire 58 is connected to a spring contact member 46 carrying a movable contact 50 cooperable with a stationary contact 54, the components being encased in an inert gas filled housing 66. When sufficient current is passed through the wire 58 via terminals 60, 64, it shortens and pulls the contact 50 upwardly to open the relay. The movable contact carrying member may have a snap acting disc portion (Fig. 5, not shown). The relay may be used to control an electric blanket, frying pan, oven or a refrigerator defrost control. Three relays (10) (Fig. 17, not shown), may be sequentially actuated via a transformer (254) and contacts (234) on a rotating drum (232) and wiper contacts (236) to sequentially control solenoids (248, 250) and a motor (252). In another embodiment (Fig. 12, not shown), the relay includes change-over contacts (180, 182) and two heat responsive wires (174, 176), each for changing the contacts from one position to the other.

Title: Improvements in and relating to the separation of metal parts cemented together by corrosion
IPC: C23G5/024
Filed: 1941-12-26
Abstract: 554,312. Separating corroded metal parts. DESHAW, Z. Dec. 26, 1941, No. 16683. [Class 91] Metal parts, particularly iron or steel machine parts, cemented together by rust or incrustation are separated or the separation is facilitated by immersing them in a petroleum distillate or like hydrocarbon in a closed vessel and raising the contents to a temperature which produces a considerable vapour pressure in the vessel, the liquid being forced thereby into the gaps or crevices between the parts to be separated. Alternatively, the parts may be heated in an atmosphere of the compressed vapour of the distillate or like hydrocarbon. Lower petroleum fractions having high penetrative powers are preferred and kerosene, particularly of burning oil quality, is specified. When used as liquid, a temperature of 60-70‹C. is suitable. The process may be effected in a pressure vessel or autoclave, and may be employed when one or more of the surfaces to be separated are of metals other than iron or steel such as copper and brass.

Abstract: 697,140. Electric signalling systems. GENERAL ELECTRIC CO., Ltd., and FIELD, R. W. G. April 25, 1952 [July 13, 1951], No. 16729/51. Class 40 (i) [Also in Group XXXVII] The invention relates to relays used to produce an alarm or initiate signal transmission when circuit-breakers or other pieces of equipment at a power station change their state. According to the invention a single relay P is used in respect of two separate pieces of apparatus, e.g., a circuitbreaker which closes auxiliary contacts OL as it trips and vice versa, and a tap-changing switch which opens or closes auxiliary contacts D as it changes its state. The contacts OL, D are series connected, respectively, with equal and opposing coils of the relay P, which has contacts P1, P2 connected in parallel in the start line 2-3, which is normally unbroken. Contacts P1 open before P2 make, and contacts P2 break before P1 make, so that a change of state of either piece of apparatus causes a momentary opening of the line 2-3 to initiate signalling. Further relays such as P responsive to change of state of other apparatus have their contacts similarly series connected in the line 2-3.

Title: Improvements in or relating to means for maintaining in synchronism a number of electric motors
Filed: 1925-07-02
Abstract: 259,285. Western Electric Co., Ltd., (Western Electric Co., Inc.). July 2, 1925. Systems depending on the use of two or more machines. - A number of series-type electric motors are provided with electrical interlocking means whereby the motors can be accelerated in synchronism with one another from an alternating-current supply. The motors are caused to run synchronously after a predetermined speed is attained. A particular motor employed, which forms the subject of Specification 260,929, [Class 35, Dynamo-electric generators &c.], starts as a series motor and runs synchronously as a repulsion motor with two fixed poiuts on the armature short-circuited. The Figure shows two machines 14, 15 having points situated 120‹ apart on one armature respectively connected to similar points on the other armature through leads 21 - - 23 and a switch 13. A switch 16 serves to short-circuit the brushes after starting, and another switch 12 short-circuits fixed points on each armature. In the preferred method of starting, the switches 16 and 12 are opened, switch 13 closed and switch 20 is closed in its lower position. The field windings are thus connected across the terminals of the alternator A; the armatures will not rotate but they may vibrate until they occupy the same relative position. Switch 20 is then closed in its upper position and both machines start and accelerate in step with each other. When the proper speed is attained, switches 16 and 12 are closed, and switch 13 may be opened. In a modification, the brushes . are not short-circuited at synchronous speed. The invention is particularly applicable in motion-picture recording or reproducing systems where one motor drives the sound record and the other the picture record.
