Abstract: 608,234. Variable-throw cranks. OLAER MARINE. Sept. 6, 1945, No. 23050. Convention date, July 3, 1944. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 6, 1945.] [Class 80 (iii)] [Also in Groups XXVI, XXVIII and XXIX] In rotary apparatus such as pumps and motors the circular translatory movement of a member 5 reciprocates pistons 3 in cylinders 2 mounted in a fixed member 1. The motion of the member 5 is effected by rotation of eccentric members 6, 7a about an axis Z, Z, the actual rotation of this member being prevented by rollers 10, 11 mounted on a member 7, engaging circular cavities 12, 13, in the members 1, 5. Gears 15, 16 mounted respectively on the members 6, 7a, mesh toothed wheels 17, 18 which in turn mesh pinions 19a, 19b, 19c and 20a, 20b, 20c, respectively, the axes ot the latter group being fixed in space. Both groups of pinions are in mesh with a freely-mounted toothed annular ring 21, so that rotation of a hub 23 to which the pinions 19a, 19b, 19c are attached, effects relative rotation of the members 6, 7a, and hence variation of the eccentricity of the member 5. As shown, the member 5 is of polygonal section, the respective faces of which co-operate with rollers 4 attached to the pistons 3. Specification 609,723 is referred to.

Title: Improvements relating to electron discharge devices
Inventor: BALKWILL JOHN TREAGUS
IPC: H01J9/20
Filed: 1959-07-06
Abstract: 890,385. Discharge apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 21, 1960 [July 6, 1959], No. 23148/59. Class 39(1) In a method of making a discharge tube, a component 18 which is to be contained in the tube envelope 1 is inserted in a subsidiary chamber 11 which is connected to the tube envelope by a duct 12 having a cross-sectional area which is small compared with its length but which is large enough to allow the component to be passed along the duct. After evacuating chamber 11 and envelope 1, a vapour is introduced into chamber 11 so as to coat the surface of component 18 with a layer of a required material, the small crosssectional area of duct 12 preventing appreciable flow of the vapour into envelope 1. Finally the component is transferred along the duct into envelope 1 and the duct is sealed off at a point adjacent the envelope. As shown, component 18 is the photo-cathode of an image-intensfying tube and is coated on one side with X-ray sensitive luminescent material from container 24 and on the other side with a caesiated-antimony layer from containers 19, 21. The method of the invention may also be used in the formation of photo-conductive or secondary-electron-emissive coatings. Metal flap 15 having been swung away from aperture 14, component 18 is moved from holder 17 to holder 31 by means of a ferromagnetic bar 26 and an external magnet. A second electrode 32 may be coated in a second subsidiary chamber connected to envelope 1 by duct 34. Before any heat-sensitive components are transferred from their subsidiary chambers into the envelope, the envelope and its remaining components may be baked at a high temperature.

Title: Improvements in or relating to data processing input devices
IPC: G06K7/10
Filed: 1960-07-05
Abstract: 881,076. Sensing record cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 5, 1960 [July 6, 1959], No. 23406/60. Class 106 (1). Record cards travelling with a long edge leading are sensed column by column by being optically projected on to a sensitized surface 33 moving at right angles to the cards and passing under a line of sensing elements adapted to sense the image. Cards pass from hopper 10 and are fed by rollers 13, 23 through the projection station where the leading edge is detected by a photo-cell 15 and a lamp 16 energized to give a flash of light. The record at this instant lies over a perforated mask 18 (shown in a lowered position for greater clarity) and its image is projected by lens 26 on to the surface 33. This surface is of the kind used in xerographic printing being charged uniformly by a wire 35 and discharged in spots where light passing through the holes in the record falls on it. The line of probes 38 read the columns in turn and pass the signals to a recorder and amplifier from which the recorded characters appear serially one after the other. Instead of an electrostatically charged surface a magnetized surface may be used, infrared radiation being used to project an image of the record on to the surface to de-magnetize particular spots.

Title: Electroplating aluminium stock
IPC: C25D3/32
Filed: 1974-05-24
Abstract: An elongated aluminium workpiece (S) such as a wire is electrolytically freed of its surface oxide layer in a first bath (10). The bath (10) contains a high-strength mineral acid and an electrode (13). Subsequently, the workpiece (S) is zinc-plated or tin-plated in an intermediate bath (11) by means of a non-electrolytic dip treatment. A further bath (20) can be used to provide the workpiece with a bronze deposit, whereafter it is electroplated with tin in a metal coating bath (12). In this arrangement, the bath fluid itself serves as electrical contact in each case, which makes it possible to dispense with fault-prone sliding or rolling contacts. <IMAGE>

Abstract: 185,732. Just-FÚle Izz¾lßmpa Ús Villamossßgi Gyßr RÚsvÚnytßrsasßg, Dr. Sept. 6,1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Filaments; residual gases.-A lamp of the inert gas-filled type is given a content of phosphorus or phosphorus compound exceeding 0.1 per cent of the weight of the incandescent body and contains gas at a pressure of less than 0.1 of an atmosphere. The phosphorus may be introduced as a coating on the filament or by making the filament of a tungsten alloy high in phosphorus. It may also be replaced wholly or in part by other elements of the phosphorus group, such as sulphur, antimony, arsenic, selenium, or tellurium, or by compounds of these, such as antimony or arsenic sulphide. In one method of making the lamp, the frame is made hollow and is filled with phosphorus. The lamp is heated on the pump in an air bath at 400‹ C. and the filament raised to incandescence. The phosphorus is allowed to vaporize for some time and after the current has been cut off and the lamp cooled, less than 0.1 atmosphere of inert gas is introduced. During the evacuation, the lamp may be cleansed by introducing and drawing off hydrogen. Lamps so heated have a reduced blackening, and when filled with pure argon are less liable to discharge through their gas content.

Title: Improvements in or relating to protective connections with excess current and direction relays
IPC: H02H7/26
Filed: 1930-08-08
Abstract: 355,013. Protective cut-out arrangements. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Aug. 8, 1930, No. 23824. Convention date, Aug. 10, 1929. [Class 38 (v).] Relay groups I, II, disposed one on each side of the section or apparatus to be protected, are interconnected by auxiliary lines L over which current normally flows from the left-hand + pole, through closed contact H<12>, relay coils H<13> H<23> closed contacts H<22> and back to the - pole. On a fault occurring in the section, one or other or both overload relays A<10>, A<20> close their contacts and energize relay coil or coils H<10>, H<20> and graded time relay or relays Z<1>, Z<2>. The relay coils H<10>, H<20> break the circuit at H<12>, H<22> of the lines L, thereby disengaging the coils H<13>, H<23> and giving a visual signal at 13, 23. The relays Z<1>, Z<2> close their contacts 14, 24 to energize the coils of energydirectional relays R<1>, R<2> which close their contacts R<11>, R<12> and R<21>, R22 to energize again the coils H<13>, H<23>, which energize the trip-coils 15, 25 to cut out the section or apparatus. If the section is fed on one side only, say the left side, the relays of group II remain idle, but those of group I operate as described. The circuit of the coils H<13>, H<23> is however made over the closed contacts H<22> instead of contacts R<21>, R<22>. In the event of a straight-through fault, the relays R<1>, R<2> operate in the same direction so that contacts R<11>, R<12> and R<21>, R<23>, for instance, close and tripping is not effected. Tripping will, however, be effected after a time-delay dependent on the distance of the fault, and assuming the latter has not been disconnected elsewhere, by the overload relays operating in conjunction with the time-relays which close their contacts 16, 25 to energize the tripcoils 15, 25. The signals 13, 23 serve also to indicate a fault in the lines L.
