Title: Improvements relating to fault-indicating apparatus
Inventor: WELBY BRIAN GUY
IPC: H04L17/20
Filed: 1951-02-27
Abstract: 705,390. Electromagnetic relays. FERRANTI, Ltd. May 12, 1952 [Feb. 27, 1951], No. 4716/51. Class 38(5) [Also in Group XL(b)] Apparatus for indicating the failure of one or the other of first and second actuating means to move a member to one or the other of two positions in response to a first or second control operation respectively comprises contacts associated with the control operations connected via contacts controlled by the movable member through an impedance across the central portion of which potential is not developed if the movable member operates correctly, and across which a potential is developed if the operation of the movable member is not in accordance with that determined by the first or second control operation respectively, the potential developed being utilized to operate an alarm. The arrangement shown in Fig. 3 is employed to produce an indication if a relay does not operate in the correct manner. A switch member 27, normally in a central position, is moved to contact 29 to operate a relay winding 10<SP>1</SP> and if the armature 23<SP>1</SP> is appropriately moved to the position 24<SP>1</SP>, a member 18 operated by the armature engages contact 19 so that current does not flow through the portion of the impedance 15 including tapping point 16. If the member 18 is not moved to the contact 19 a potential is produced at the point 16 and an alarm relay 42, which may be a flap indicator, is operated. Similarly when the member 27 is moved to contact 30 to de-energize the winding 10<SP>1</SP>, if the armature 23<SP>1</SP> is not retracted so that the member 18 engages the contact 19, a potential is developed at the tapping point 16 to operate the relay 42. If, when member 27 engages contact 30, member 18 is in engagement with contact 21, there will be no drop in potential across the central part of the impedance 15 and the relay 42 will not operate. The relay 42 may be provided with a delay device, such as a slug, to prevent its operation during the transit time of the member 18.

Abstract: 944,348. Soldering. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Jan. 18, 1962 [Feb. 9, 1961], No. 4820/61. Heading B3R. [Also in Division H1] In a method of manufacturing a semiconductor rectifying device in which the various components are assembled in a sandwich and subsequently fused together by the application of heat, a component is treated to inhibit " wetting " of its periphery by solder of an adjacent solder foil during the fusion operation. The treatment preferably comprises forming an oxide coating on the periphery by painting with oxide or by chemical action, e.g. immersion in nitric acid. If the component is wholly immersed in acid, then oxide must be removed from that surface intended to make contact with another component. The treated component is of molybdenum.

Title: Improvements in or relating to non-metallic sliding clasp fasteners
IPC: B29D5/00
Filed: 1941-04-25
Abstract: 548,878. SIiding-clasp fasteners. CORNER, G. H. C., FLETCHER, O. E.. MURRAY, E. A., and LIGHTNING FASTENERS, Ltd. April 25, 1941, No. 5372. [Class 44] The fastener members of a sliding-clasp fastener are formed by moulding, pressing, stamping or other processes from proteinic material such as casein in an uncured state. The members so formed are applied to the stringer tapes and secured thereon by treatment with an alkaline or basic reagent, preferably in aqueous solution, this treatment being applied long enough to allow superficial formation of a soluble compound which penetrates the pores of the tape. The alkali is then removed or neutralised and the members dried and cured to render them hard and resistant to heat, water, the usual dry-cleaning solvents and chemical action by treatment with formaldehyde. The proteinic material extracted from ground nut meal by treatment with alkaline or saline solutions is given as an alternative .to casein. The Specification gives .880 ammonia solution as a suitable alkali for the above-described attachment process, with, as alternatives, aqueous solutions of hydroxides, carbonates, silicates or triphosphates of alkali metals or borax, or concentrated solutions urea, thio-urea, or substituted compounds thereof. As hardening reagents alternative to formaldehyde aqueous solutions of potassium dichromate, chrome alum, tannic acid and pioric acid are given. By way of example casein with a plasticiser is formed into a strip from which integrally connected fastener members are made as in Specification 426,961, the members being then severed and mounted on a tape as in Specification 444,405. Specification 548,879 also is referred to.

Title: Improvements in or relating to position indicating apparatus for use with radio navigation systems
IPC: G01S1/02
Filed: 1949-02-28
Abstract: 665,135. Electric selective and correspondence signalling. DECCA RECORD CO., Ltd., ROBERTS, G. E., and COPPING, J. B. Feb. 27, 1950. [Feb. 28, 1949] No. 5431/49. Drawings to Specification. Class 40 (i). [Also in Groups XX and XL (c)] The Provisional Specification describes, in connection with a course recording and indicating instrument (see Group XX) comprising a cylindrical rotatable chart and a cursor moving axially with respect thereto, (1) A servo-mechanism which forms a torque amplifier and which is adapted to rotate the input shaft of a gear box in accordance with the phase relationship of two signals. The servo-transmitter comprises a phase-indicating meter as described in Specification 620,480, [Group XXXVI], modified so that the rotor instead of operating a registering mechanism and pointer carries on its shaft a light radially extending platinum strip the end of which is disposed between a pair of closely spaced platinum contacts on an insulating disc rotatably mounted adjacent the end of the rotor spindle, and is rotated through reduction gearing from a reversible electric motor energized under control of thermionic valve switches when the platinum strip contacts either of said platinum contacts to drive the disc in such direction as to bring that making contact away from the strip until the two contacts are equally spaced on either side the strip. Thus the disc always follows the movements of the rotor. (II) A servo-mechanism, the transmitter of which is controlled from the output shaft of a gear box to control a servo-receiver at a distant location which servo-mechanism is adapted to vary as required, the relative rotational movement between a receiver. and its transmitter so as to vary the relative values of the co-ordinate movements of the chart and cursor. The transmitter of such a servo-mechanism comprises a fixed changeable multi-segment commutator and e.g. four operating brushes rotated by the output shafts of the gear box, the brushes being so arranged and the commutator segments so interconnected that the brushes are energized through the segments in a cyclic order which is changed cyclically as the brushes rotate relatively to the commutator. The servo-receiver has as element, e.g. a brush movable relative to commutator segments energised in a cyclic order from the transmitter and the brush takes up an angular position according to the cyclic order of energization of the transmitter brushes. Means, such as a switch, is provided either for changing the commutator segment interconnections so as to alter the amount of angular displacement of the brushes necessary to effect each step of change in the cyclic order or for changing the receiver segment inter-connections so as to alter the amount of angular displacement of the receiver brush for each step change in the cyclic order of energization of the receiver.

Hot (or cold) water is circulated from the boiler 1 (or refrigerator in the case of a cooling system), or accumulator 3, by means of a pump 5. The Specification as open to inspection under Sect. 91 comprises also a central heating (or cooling) system having an accumulator for the cooled (or warmed) water in the return circuit from the heating elements which may be of any type, and means are provided for putting the boiler or refrigerator out of circuit and feeding the elements direct with water from the accumulator. The water in the accumulator may be heated by circulation through the boiler or by an electric heater while the radiating elements are out of circuit e.g. overnight, to provide for rapid heating of the elements when again put into operation. Means may also be provided for cooling the water in the accumulator while the heating elements are in operation. This subject-matter does not appear in the Specification as accepted.
