Patent GB-731918-A (GB)
Title: Improvements in and relating to control devices
Inventor: HERBERT DAVID CROUCH
IPC: G05B11/01
Filed: 1951-05-09
Abstract: 731,918. Electric control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 8, 1952 [May 9, 1951], No. 10921/51. Class 40 (1). An electronic trigger circuit is controlled by a mechanical switch which when open has a very small separation of its contacts, of the order of one ten-thousandth of an inch. As shown, for maintaining constant the strain of a specimen 1, in stress relaxation testirg, in which the load on the specimen, usually at elevated temperature, needs only to be reduced, a single switch 4, 5 suffices. Strain of the specimen 1 rotates anti-clockwise the rhomb 2 of a Marten's type extensometer, which, through a balanced lever arm 3, closes the switch 4, 5 to short-circuit the batteryresistor combination 19, 20, Fig. 2. This reverses the condition of the Schmidt electronic trigger circuit shown, to de-energize the relay 14, which through a mercury-switch relay 23 starts the motor 25, Fig. 1. The motor through reduction gearing 26 and a handcontrolled clutch 27 reduces the load on the specimen until the contacts 4, 5 open and again reverse the trigger circuit to stop the motor which preferably incorpoiates dynamic braking. By using a Schmidt trigger circuit which will function with a two-volt battery 19, and dimensioning the resistor 20 so that the current handled by the switch 4, 5 is low, i.e. less than 200 microamperes, the switch will trigger the circuit when its contacts separate by 0.0001 inches. If two-way control is needed the moving members of the switch may move between two fixed contacts, each controlling a corresponding trigger circuit. A neonstabilized rectified A.C. supply is preferably used for the trigger circuit for stability. The invention is applicable also to controlling feed motions of machine tools; and controls to be actuated at specific positions of measuring instruments such as heating or cooling devices controlled by thermometers or pumps controlled by pressure gauges.

Title: Improvements in vibrating reed relays
IPC: H02J13/00
Filed: 1956-04-13
Abstract: 783,252. Electromagnetic relays. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. April 13, 1956 [April 13, 1955], No. 11303/56. Class 38 (5). A resonance relay intended to respond to carrier signals having a frequency of, e.g., three and a half times that of a mains frequency of 50 c.p.s. comprises a reed 4 tuned to the carrier frequency and mounted on a steel block 6, the free end of the reed extending through an air gap 3 of a core 2 energized by a coil 1 of a circuit tuned to the carrier frequency, the block 6 and core 2 being connected by a polarizing magnet 7. Thus on receipt of a carrier signal of sufficient duration a pawl 8 on the reed 4 rotates a wheel 9 to turn a shaft 10 at a speed high enough to operate an electric contact through a centrifugal device (not shown). To prevent undesired operation of the shaft 10 by a disturbance of high amplitude having a frequency equal to or near the carrier frequency, a second reed 5 is provided tuned to a frequency about  10 c.p.s. different from that of reed 4 so that it vibrates only weakly during transmission of a normal carrier signal and performs no controlling action. However, on receipt of a highamplitude disturbance as aforementioned the reed 5 vibrates and a finger 12 thereon immediately maintains a resilient lever 13 in a raised position, this lever being fixed by a member 15 to the core 2 and normally engaging the finger 12, the natural period of the lever being large compared with that of the reed. In its raised position, the lever 13 engages a ratchet-wheel 14 on the shaft 10 and thus the shaft is locked against rotation before it has attained the necessary speed to operate the controlled con tact. Specification 576,508 is referred to.

Filed: 1933-04-19
Abstract: 413,829. Securing bearing-races &c. on shafts. RENOLD & COVENTRY CHAIN CO., Ltd., and RENSHAW, A., Renold Works, Didsbury, Manchester. April 19, 1933, No. 11488. [Class 80 (ii).] A cylindrical metal member 10 is secured in a hole in a second member 12, such as a bearing-race, of harder metal by forming on the surface of the hole one or more projections 14 and depressions 16 and pressing the second member 12 over the cylindrical member 10 with the depressions preceding their associated projections so that metal removed thereby from the surface of the cylindrical member 10 is forced into the depressions. The projections and associated depressions may be isolated from one another or they may take the form of an annular ridge or portion of less diameter than the remainder of the hole immediately preceded by an annular groove for the reception of the metal removed from the cylindrical member. Alternatively, an annular groove may be associated with isolated projections and depressions, with or without the annular ridge. The depressions and projections are formed by pressing obliquely into the surface of the hole a flat ended tool which scores a sloping groove in the surface and heaps up the displaced metal to form the projection. In another form, the projections and associated depressions are disposed in helical lines and the members rotated relatively to one another during the pressing operation. Specification 297,570, [Class 24], is referred to.

Title: Improvements in and relating to thermostatic switches
IPC: H01H37/12
Filed: 1935-04-16
Abstract: 455,288. Thermal switches. TURNER, C. A., 33, Crespigny Road, Hendon, and DIAMOND H. SWITCHES, Ltd., Gunnersbury Avenue, Chiswick, both in London. April 16, 1935, No. 11708. [Class 38 (v)] In a thermostatic switch a thermal element such as a bimetallic coil 16 rotates a shaft carrying a cam 13 which engages a roller 12 on a contact arm 1 pivoted at 9 and biassed by a spring 6 causing a contact 2 to move away from a contact 3. The cam also has fixed to it a pointer 25 which moves over a dial 20 indicating the temperature. The dial may be adjusted relatively to a fixed pointer 24, indicating the temperature at which the circuit is to be broken, by rotating a knob 24<1> which turns a wheel 22 gearing with teeth 21 on the dial. The dial is also adjustably connected to a toothed plate 26 by means of a screw 28 which passes through one of a number of holes in the dial and engages between the teeth of the plate 26, and the plate 26 is connected by a sleeve 27 to a disc 19 which carries a pillar 18 connected to the one end of the bimetallic coil by means of a link 17. Rotation of the knob 24<1> therefore not only moves the dial 20 but also the bimetallic coil and the cam and pointer 25. In a modification, suitable for use with a water heater, Figs. 3 and 4 (not shown), the flat bimetallic coil is replaced by a helix. In other modifications, Figs. 5 and 6 (not shown), the adjusting knob 24<1> is mounted on the end of a flexible shaft coupled to the switch. In place of a single cam there may also be two ; one operating in advance of the other and cutting off part only of the heater and the other operating later and cutting off the remainder.
