Title: Improved electrolytic process
IPC: C25D5/18
Filed: 1933-08-09
Abstract: 423,310. Electrodeposition of metals and alloys. KUPPEL & SIMEANT, 3, Place Sacco Vanzetti, Clichy, Seine, France.- (Assignees of Kuppel, H., and SimÚant, L.) Aug. 9, 1933, No. 22301. Convention date, Aug. 11, 1932. [Class 41] In the electrodeposition of copper, iron or zinc from solutions thereof, the electromotive force at the electrodes is raised to increase the current intensity therebetween until it exhibits a tendency to rise simultaneously with a decrease in the electromotive force, whereupon the electromotive force is progressively diminished to a point at which the temperature of the electrolyte becomes stabilized. The control of the electromotive force should preferably be effected by controlling the excitation of the dynamo supplying the current. The process may be combined with the use of turning cathodes and smoothing devices, especially such as are described in Specification 282,274, [Class 41]. The products obtained do not normally require any mechanical polishing. Examples are given. The Specification as open to inspection under Sect. 91 comprises also the deposition of metallic alloys from baths containing electrodes of different metals by the same method, the deposition of an alloy of copper and chromium being specifically mentioned. The process is also not specifically restricted to the deposition of the metals copper, iron, and zinc. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to semi-conducting resistances provided with metal contacts
IPC: H01C1/144
Filed: 1946-07-26
Abstract: 627,576. Non-metal resistances ; temperature variable resistances ; direct connections between conductors. PHILIPS LAMPS, Ltd. July 26, 1946, No. 22324. Convention date, July 30, 1945. [Classes 37 and 38 (i)] A resistance has metal contact members and is constituted by a sintered semi-conducting material which is conducting owing to an excess of cation, the union between resistance and contact members being constituted by a sintered or molten mass which contains both the metal present in the semi-conductor as cation and the metal of which the contact member is made or with which the latter is coated. A mixture or an alloy may be utilized and if desired other metals may be added which serve to reduce the sintering or melting temperature. In one embodiment copper or copper clad iron terminals are mounted on a resistance element which is in the form of a sintered insulating magnesia mass with embedded conducting particles of partly reduced titanium oxide. To mount the terminals about 10 grams of a mixture of Cu, Ti and Sn in a molecular ratio 55 : 10 : 2 is worked with a solution of 2 grams of creso-formaldehyde resin in 10 c.cms. of alcohol into a paste. A layer of the latter is then applied to the ends of the resistance element and the contacts slipped on ; the assembly is then dried and sintered at about 1000‹ C. in pure hydrogen. The Specification as open to inspection under Sect. 91 comprises also an embodiment in which the resistance element is primarily C d O and the terminals tinned iron ; in this case Cd and Sn form an alloy in a molecular ratio 4 : 1 and the union is effected by melting at 250‹ C. in nitrogen.

Title: Improvements relating to Infra-Red and Optical Signal Detecting Devices with particular reference to Background Discrimination
Inventor: FARMER CROFTON BERNARD
IPC: G02B13/14
Filed: 1961-06-20
Abstract: 1,157,951. Radiation detection. ELECTRIC & MUSICAL INDUSTRIES Ltd. 14 June, 1962 [20 June, 1961], No. 22349/61. Heading H4D. A signal detecting device comprises two or more strip-form detecting elements, means for focusing radiation in the form of a line image upon said elements in such a way that radiation from a particular source is focused upon only one detector at any one moment, whilst radiation from a diffuse source is focused upon both or all said detecting elements in substantially equal amounts. An infra-red detecting device is described with reference to Fig. 1 enabling the detection of a particular source even when the level of the signal is considerably less than the level of background radiation within the same frequency band. As shown the device comprises a lens 1 forming part of a toroid and focusing radiation from a point source 2 into a line image such as line 2a in the image plane of the lens. The lens 1 and two infra-red detectors D 1 , D 2 , situated in the image plane of the lens, are mounted in a vehicle in such a position that relative movement between the vehicle and the source causes the focused line image to be substantially parallel with the longer dimensions of the detectors and to move in a direction perpendicular to those dimensions. The outputs of the detectors are connected to the ends of a potentiometer P 1  (Fig. 2) and the potentiometer tapping is adjusted so that there is no signal when the detectors are equally energized by the background source and by the point source. However, on movement of the point source to position 3, for example, the image falls along line 3a and the detectors are unequally energized to produce a signal. In addition movement of the point source can be detected since this results in each detector being illuminated in turn and consecutive signals of opposite polarity being produced at the output.

Title: Target finder for missiles
IPC: F41G7/22
Filed: 1958-07-11
Abstract: 902,615. Automatic steering control systems. ELTRO G.m.b.H. July 13, 1959 [July 11, 1958], No. 22405/58. Class 38 (4). [Also in Group XXI] In a system for automatically homing a missile on to a target, means on the missile, responding to electromagnetic radiation from the target when the missile is not heading towards the target, controls the detonation of a charge carried by the missile to correct the course of the missile. As described, a small rocket, e.g. a craft-to-craft missile, carries at its nose a reflector 17, Fig. 5, the axis 14 of which is inclined to the axis of the missile so that, as the latter spins, an area SK, Fig. 4, is scanned ahead of the missile. Normally, when the missile is on course, the target is in the blind area BK, but should the relative attitude change, infra-red radiation from the target is effective through a photo-cell 19 and amplifier 20 to render a thyratron valve 22 conductive to detonate an auxiliary charge 16<SP>1</SP> which, as shown in Fig. 3, is suitably positioned on the missile to correct the course of the missile. Charge 16<SP>1</SP> is then automatically replaced by another charge 16 from a magazine so that when a condenser 25 recharges, further corrections may take place. Other forms of electromagnetic radiation transmitted from a launching craft and reflected from the target may be used.

Abstract: 863,734. Reciprocating pumps. SOC. INDUSTRIELLE DE BREVETS ET D' ETUDES S.I.B.E. June 30, 1959 [July 1, 1958], No. 22464/59. Class 102(1). A reciprocating pump, in particular a fuel pump, combined with a reserve liquid chamber comprises a diaphragm 5 having inlet and outlet valves 2, 3 and a reserve chamber 11 located, upstream of the inlet valve. A first passage 20a 20 leads from the bottom of the reserve chamber to the suction valve while a second passage 25, 24, 20b, 20 leads from the top of the chamber to the suction valve. A single valve member 21 controls the passages 20a, 20b, and is connected to a diaphragm 22 acted upon by a spring 23 and the pressure in a chamber 26 which communicates with the downstream side of the outlet valve by a passage 27. At the commencement of operation the spring 23 causes the valve 21 to close the passage 20b and liquid is drawn from the bottom of the reserve chamber. When the delivery pressure exceeds a predetermined value the passage 20a is closed and the passage 20b opened whereby vapour in the reserve chamber is pumped until the liquid level rises to N or the delivery pressure falls. In a modification the second passageway is in direct communication with the suction valve and has an orifice to regulate the vapour flow. The first passageway is controlled by a valve as above.

Title: Improvements in automatic machines for the manufacture of screws and other repetition work
IPC: B23B7/02
Filed: 1920-07-29
Abstract: 172,063. Schreier, E., and Jenny, R. July 29, 1920. Lathes; screwing; steady rests.-In an automatic machine for making screws and for other repetition work, the stock is fed through, and rotated by, the spindle 2 carried in a headstock 3 which is moved to the left to feed the stock by an adjustable cam 12 and returned by a spring. The cam 12 is carried by a slide which is reciprocated by a cam 14 and a spring. The movement of the headstock is limited by an adjustable screw and a stop 2<1>. The gripping- gear for the stock in the spindle is actuated by cams 7, 8 and levers 4, 5, 6. When the headstock is moved to the right, the stock is free in the spindle and is held in a bracket 40 by a spring-plunger 41, Fig. 2, actuated by a cam 43 and a lever 42. The turning-tool 16 is secured in a vertical slide carried by a cross-slide 17 movable in guides in a longitudinally movable saddle 15 which carries a work guide 18 close to the tool 16. The saddle is moved to the right, to effect the turning-down of the stock, by a cambar 19 reciprocated by a pair of cams 25, 26, and is returned by a spring. The bar 19 carries a pair of adjustable inclined pieces 20, 21 which coact with rollers 23, 24 on the saddle. The cross-slide 17 is moved, against a spring 39 which feeds the tool, by three cams 30, 31, 32 and levers 27, 28, 29, which act through adjustable screws on an angle-plate 34 which again moves the slide by means of a sliding-rod 38. The work can thus be given various diameters at different points of its length. After a piece of stock has been turned it is fed to the left, and while a second piece is being turned the first piece, if a screw, is operated on by a screwing device 50 which is brought into action by cams 51, 52. The dies are rotated at a greater speed than the stock, so that after the screwing operation is complete they can be stopped and are then automatically screwed off the work. After the screwing operation has been completed a parting tool 46 is advanced to sever the screw from the stock. The tool 46 is carried by a cross-slide 45 which is moved, against a spring, by a lever 47 actuated by a cam carried on a slide 48, moved in one direction by a cam 49 and in the other by a spring. All the rotary cams are mounted on a shaft 9 which is driven, independently of the lathe spindle, by wormgear 53.
