Inventor: METCALFE HARRY FRANCIS
IPC: G01P15/125
Filed: 1951-04-12
Abstract: 715,750. Photo-electric control of measuring instruments. BRITISH THOMSON-HOUSTON CO., Ltd. March 27, 1952 [April 12, 1951], No. 8539/51. Class 40 (3). [Also in Group XXXVIII] Acceleration, pressure, weight or force is measured by producing a corresponding torque on a coil C suspended in a magnetic field, movement of the coil effecting mechanically a differential response of an inductive, photo-electric or, as shown, a capacitative pick-off P1-P2-P3. The pick-off response is by means of a bridge circuit translated in known manner into an alternating voltage of corresponding magnitude and phase sense from which a magnified direct current of corresponding magnitude and sign is derived and fed to the coil C to produce a counterbalancing torque thereon. As the coil C does not move appreciably the D.C. is a measure of the acceleration &c. A dynamometer type of instrument may be used in lieu of the permanent magnet-moving coil type shown, one set of coils carrying a fixed current and the other set of coils the current measuring the acceleration. A magnetic amplifier may be used.

Patent GB-825439-A (GB)
Title: A device for automatically setting a machine element to a pre-opted position either in linear or angular measure
IPC: B23Q16/00
Filed: 1957-03-18
Abstract: 825,439. Machine-tool details. BERLINER MASCHINENBAU AKTIENGESELLSCHAFT VORM. L. SCHWARTZKOPFF. March 18, 1957 [March 28, 1956], No. 8771/57. Class 83 (3). Means in a machine for automatically setting an element to a predetermined position (e.g. a drill-slide 16 or an indexing - table), comprises adjustable stop members 2 on a longitudinallydisplaceable rail 1, and a contact finger 15, which is connected with the element, and which can be automatically intercepted by a preselected stop member. The stops 2 are mounted for relative adjustment on a bar 1 movable on rails 3 by a screw-and-nut drive 4, 5. The screw 5 is rotated by a motor 10 through reversing gears 6 and magnetic clutches 7, 8. The rail 1 can be moved up to a distance equal to treble the space between the stops, the distance being indicated on a revolution counter 9 and limited by switches 12, 14. The stops 2 co-operate with a contact finger 15 carried by the machine slide 16, or attached thereto by a link 19 and a slide 17 moving on a bar 18. The finger 15 is normally displaced from the line of stops, but can be moved laterally to contact a preselected stop, whereupon a microswitch 22 is actuated through a lever 21 to stop the slide. The lateral movement of the finger is effected by an electromagnet 20 which is actuated when a carbon brush 30 contacts a segment 29 which has been energized by the setting of a control lever 24. In operation, the slide 16 is moved hydraulically under electrical control, so that a drill on the slide 16 is positioned over a centre which is to form a reference zero. The bar 1 is then moved until a dog 11 thereon actuates a switch 13. The finger 15 is next moved into operative position, the rail 1 is moved until the finger 15 is actuated by a stop 2 to stop the motor 10, and the revolution counter is set to zero. Dimension setting levers 24-28 are also set to zero, and the slide can then be traversed either to the left or the right by an amount set by the levers. The first lever determines the direction of traverse of the machine slide, and selects the stop member which is to be contacted by the finger. The initial movement of the slide is such that the finger always approaches the selected stop from the same side, to eliminate back-lash. Thus, in certain cases, the slide movement is reversed before being stopped. The slide is automatically clamped in its adjusted position. In a modification, the finger 15 is deflected laterally by oblique faces on the stops. In the case of a table which is to be indexed, the stops are arranged in a circle.

Title: Arrangement for controlling or releasing electric currents by means of mechanical members
IPC: H01H45/00
Filed: 1930-03-19
Abstract: 351,455. Relay devices. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. March 19, 1930. No. 8852. Convention date, Feb. 15. [Class 118 (ii).] Electric currents are released or controlled by means of mechanical members governing the direction of air currents which influence the temperature of a device, the temperature of which controls the strength or release of the electric currents. The mechanical members are described as screens on the hands of measuring instruments. An air current from a nozzle 7, Fig. 1, impinges on a bimetallic strip 1 fixed to a contact arm 2. When the screen 9 mounted upon the indicating needle 8 moves to cover the nozzle 7, the temperature of the strip 1 rises and it bends to close the contacts 2, 4 controlling a circuit across terminals 5, 6. In a modification the air current controlled by the screen 9, Fig. 2, cools the resistances 14, 15 of a bridge 14 .. 17 and controls the e.m.f. across the points 10, 11 when potential is applied across points 12, 13. The air current may be generated naturally by fitting the resistances 14, 15 in the bottom of a vertical tube which will act as a chimney when one of its ends is uncovered bv the screen 9. In another modification two nozzles 7, 71, Fig. 3, are provided fixed to a plate 18, deflection of the needle 8 cooling either the coils 14, 15 or 16, 17 causing a current flow in the windings 21, 22 to actuate a polarized relay 20. Contacts 23, 24 or 23, 25 are closed and the circuits across contacts 51, 6 and 5, 6 may be arranged to control the current indicated by the needle 8 to bring the latter back to normal position. An arm 19 integral with the disc 18 may be used to regulate the zero position. The air currents may be generated by means of a telephone fed with alternating current at say fifty cycles using the sound-nozzle principle as described in Specification 206,853, [Class 118 (ii), Signals]. The whole apparatus may be built into a casing to be fitted to any measuring instrument. The polarized relay 20 may be replaced by two opposing relays in parallel each operable by current in one direction only.
