A disc-shaped semi-conductor arrangement is mounted in a housing comprising a tube of insulating material closed by metal end members each of which comprises a thick central portion and a thin peripheral portion of different metals, the coefficient of expansion of the peripheral portion being closer to that of the insulator than is the coefficient of expansion of the central portion. As shown, Fig. 1, a rectifier comprises a silicon disc 2 with alloyed aluminium and antimony-containing gold electrodes at its major faces bonded to molybdenum carrier plates 3, 4, plate 4 having a silver layer 6 or being bonded using a silver foil 6. The carrier plates 3, 4 are contacted by copper plates 12 to which annular peripheral portions 10 of an iron-cobalt-nickel alloy are hard-soldered. The inner faces of plates 12 are lapped and silver foils 5, 7 are inserted between them and the adjacent carrier plates 4, 3 which are centred by pins 13. Alternatively the molybdenum carrier plates may be silver-plated on their outer faces. The edges of the peripheral portions 10 are welded to flange members 9, also of an iron-cobalt-nickel alloy, hard soldered to a ceramic tube 8. An exhaust tube is provided in one portion 10. The housing may be adapted for use with an SCR by hard-soldering a ceramic bushing (17), Fig. 2 (not shown), in one peripheral portion (11), inserting an iron-cobalt-nickel pin (19) through bushing (17), hard-soldering the head of pin (19) to the end of bushing (17), and soft-soldering an insulated conductor 20 to the head of pin (19). The SCR is surrounded by a frame member provided with a spring contact which presses against the gate electrode of the SCR and is connected to the inner end of pin (19) by a silver wire. One or both of the carrier plates may be hardsoldered to plates 12 and the connection to the electrodes of the semi-conductor device may then be by pressure only or by a subsequent soft-soldering process using heat and pressure. A suitable soft solder is 80 : 20 gold-tin alloy and a suitable hard solder is 65 : 27 : 4 : 4 silver-copper-manganese-nickel alloy. The device may be clamped between liquidcooled copper bodies (31), Fig. 3 (not shown), by means of a steel frame (33, 34) and a clamping screw (36) which bears on an insulating disc (37). Rings (38) are provided on bodies (31) to centre the semi-conductor device (30) and a ring (39) is provided on base plate (33) to centre the lower cooling body. The clamping frame is unnecessary if plates (12) are soldered to carrier plates (3, 4).

Title: Improvements in or relating to preselector mechanisms for change-speed gears
IPC: F16H61/02
Filed: 1948-02-12
Abstract: 650,566. Controlling variable-speed gearing. PARKINSON, R. M. Feb. 12, 1948, No. 4088. [Class 80(ii)] A pre-selector and actuating mechanism for change-speed gears comprises a plunger-like member 30 on a shaft 39 which is rotated to select a gear ratio and moved axially to engage the gear selected. The plunger 30 co-operates with sliding rods 11-14 corresponding to the various ratios and arranged around the wall of a cylindrical member 20. These rods have cut away portions at their upper ends to form shoulders 31 adapted to be engaged by a flange of the plunger on its downward movement to be moved to neutral position. The plunger is provided with a series of radially projecting pins 33-36 one of which is adapted to engage in a notch 32 of a corresponding rod 11-14 when the plunger is rotated to select a gear and then moved downwards, the pin, such as 33, riding over the shoulder 31 of the selected rod against spring pressure and dropping into the notch 32. Subsequent upward movement of the plunger 30 by a spring 43 will then carry the selected rod 11 with it to operate the gear shift through a rocking lever 25, 28. The rotation of the plunger 30 and its shaft 39 is effected by a selector control lever 41 and its axial movement is effected through a bellcrank lever 56 by, for example, the clutch pedal 49, Fig. 6, of the vehicle. A lost-motion connection 53, 54 is provided in this case so that on depression of the pedal the clutch is first disengaged and the plunger 30 then moved downward to place any previous gear in neutral, and, on release of the clutch pedal the selected gear is first engaged and the clutch then re-engaged. The axial gear engaging and disengaging movement of the plunger may be effected by fluid-pressure or suction on a piston under control of a valve connected to the clutch pedal.

Abstract: 447,996. Gas governors. GAS LIGHT & COKE CO., and THOMSON, S. M., 84, Horseferry Road, Westminster. Feb. 9, 1935, No. 4227. [Class 135] A gas governor has the load on the governor valve varied by movement of a member along the balance arm of the governor effected under the control of clockwork mechanism. The Figure shows the invention applied to an auxiliary gas governor which is arranged to vary the loading of a main governor which latter controls the pressure in a gas main. The spindle 2 of the governor 1 is loaded by a lever 4 carrying a normally fixed weight 6 and a movable weight 8, the latter being mounted on a trolley 9 running on a track rail 10 secured to the lever. The trolley has an apertured lug 11a engaged by a pin 11 carried on a flexible stainless steel tape 12 stretched between a pair of coupled quadrants 13, 14 so that rotation of the quadrants causes a rectilinear displacement of the weight. A drum 18 adjustably secured to the quadrant 14 is wrapped about by a wire 19 attached at vertically spaced points 20, 21 to a sliding rod 22. This rod is depressed from time to time by the engagement of one or other of the rods 24, 25 with a collar 32. The rods are pivoted to bell-crank levers oscillated by clock driven cams rotating once in 24 hours and the particular rod in service is selected by clock driven cams 33 rotated once a week. In lieu of the two quadrant members there may be used a gear wheel or segment meshing with a horizontally slidable rack connected to the trolley. In a modification, the rod 22 is coupled to the trolley by a Bowden wire. In a further modification, the weight is fixed and the fulcrum of the lever adjusted by the movement of the rod 22 acting directly or through a bell - crank lever. Specification 322,887, [Class 135], is referred to.

Abstract: 1303521 Detecting cracks in steel strip BETHLEHEM STEEL CORP 29 Jan 1970 [31 Jan 1969] 4326/70 Heading G1A In an apparatus for detecting edge cracks in a moving strip 16, including a light source 72 and two photodetectors, e.g. photomultipliers, 86, 88, wherein the direct light path between one detector and the source is displaced both laterally and longitudinally of the strip from the direct light path between the other detector and the source, means 164 are provided for producing an output signal indicative of a crack only when an output signal from one detector precedes an output signal from the second detector by the time taken by the strip to travel from the first light path to the second. The light paths are defined by the apertures 104, 106 in a light shield 92, and each path contains a U.V. transmitting filter 78, 80, a window 82, 84 and a lens 90, 91. When an edge crack passes between apertures 104 the resulting signal pulse from photomultiplier 86 is supplied to a gate 156, which also receives pulses from a strip driven tachometer 150. The resulting output pulse from gate 156 is delayed in a pre-set counter 158 for a time interval corresponding to the strip travel time from apertures 104 to 106. The pulse is then fed to gate 162 to coincide with a pulse produced by photomultiplier 88 in response to the same crack. The resulting signal from gate 162 may be used to mark a data record, sound a horn or illuminate a signal light. The output signal from bistable switch 160 is also supplied to a further pre-set counter 168 which introduces a time delay before resetting the various bistable switches, thus allowing for errors in calibrating the tachometer. Only edge cracks of sufficient lateral extent to cross both optical paths will produce a warning signal, pinholes passing through undetected. The position of the shield 92 with respect to the strip edge is maintained constant by both a coarse and a fine control. The fine control is provided by a system including a light source 100 and detector 102. The detector output feeds a rack and pinion drive Figs. 5, 6 (not shown). The coarse position control comprises a U-shaped housing surrounding the light shield 92 Figs. 1-3 (not shown), this housing containing three filament lamps (58, 60, 62) located above the strip cooperating with three photo-detectors (66, 68, 70) located below the strip, there being a lens (64) in each light path. The photo-detector outputs are fed to a motor which controls a screw drive (50).
