Abstract: 1,037,358. Semi-conductor rectifiers. GENERAL INSTRUMENT CORPORATION. Aug. 4, 1964 [Aug. 6, 1963], No. 31262/64. Heading H1K. A solid state rectifier 4 is bonded to at least one terminal member of a material, such as silver, which diffuses heat rapidly and the rectifier and attached member or members are mounted in an enclosed housing B. The Specification defines thermal diffusivity and requires that the diffusivity of each terminal member exceeds that of copper and that the volume of each such member is at least four times the volume of the rectifier 4. Preferably there are two such members 10 and 12, one of which has a larger cross-section than the other. The exposed edges of the rectifier and the smaller of the attached members are covered with a plastic-e.g. silicone rubber-coating 20. The rectifier shown is a PN junction silicon rectifier disc of circular section and with tapering sides. The largest diameter is on the P side of the junction in contact with the larger silver member 10. In another form (Figs. 3, 4, not shown) the rectifier is of square section and parallel sided, the silver members also being of square section-one larger than the other and both larger than the rectifier. The rectifier of Fig. 1 is formed by doping a silicon wafer, attaching the silver members, e.g. by soldering, etching the wafer edges in a nitric-hydrofluoric-acetic acid mixture, passivating the wafer (to remove silver migrated during the etching) by repeated alternate washings with nitric acid and a low water content, e.g. isopropyl-alcohol, and applying the silicone rubber coating 20 in a suitable jig (Fig. 2, not shown). The device is then encapsulated and fitted with the leads 26 and 24, which are respectively of copper clad iron and copper clad nickel.

Title: Improvements in luffing cranes
IPC: B66C23/10
Filed: 1919-12-20
Abstract: 160,544. Souness, T. Dec. 20, 1919. Jib cranes. - Comprises means for lufting jib cranes so that the load remains horizontal during the operation. In the construction shown in Fig. 1, the compensation is obtained by the movement of the balance weight 8. The hoisting- rope 11 passes from head to heel of the jib, round hoisting rams 14, and thence round the pulley 10 on the balance weight to a fixed point. The balance weight is connected by a cord 5 to a crosshead 4 actuated by a link 3 and sliding in guides arranged vertically above the jib pivot. The cross-head is arranged to rise and fall half the vertical distance travelled bv the jib head, and this movement is doubled by the pulley 10 to effect exact compensation. Fig. 2 shows a modified construction in which the compensating pulley 18 is below the jib pivot at the end of a rod depending from the cross-head. The hoisting-rope in this case passes to the heel of the jib and thence round multiple pulleys 2, 18 to a drum 19. The cross-head 4 is connected to the balance weight 8, which in turn is connected to the luffing- drum 21. Fig. 3 shows a construction in which the link 3, the counterweight arm 23, the lower end of the jib, and the base form a jointed parallelogram with all four sides equal. The crosshead 15 moves along the link 3 as the latter rises and falls. The compensating pulley 26 is arranged similarly to Fig. 2.

Abstract: 1,224,386. Heating and cooling windows. SULZER BROS. Ltd. 4 July, 1968 [4 July, 1967], No. 32044/68. Heading F4S. The space between wall members formed at least to some extent as a window contains a light transmitting medium, e.g. air, which is forced by a fan over at least one heat exchanger. The space may be substantially completely enclosed or it may have entry and/or exit apertures for fresh air and/or room air, the apertures being closable by flaps. Alternatively, the space may communicate with ambient atmosphere through a pressure-equalizing aperture containing a filter and/or siccative. The fan and a vertically mounted heat exchanger may be arranged in a portion of the space which is divided therefrom by a vertical partition to one side of the space and the air is distributed by horizontally mounted, apertured deflectors. In a further embodiment, the heat exchanger is mounted horizontally adjacent the top or bottom of the space and the flow of air passes consecutively through two sections formed by a central, vertically arranged lighttransmitting partition parallel to the front and back walls of the apparatus.

Abstract: 1,145,250. Secondary fuel cells. SIEMENS AG. and VARTA AG. 12 July, 1967 [12 July, 1966], No. 32047/67. Heading H1B. A secondary fuel cell has an ion-permeable oxygen anode disposed between a hydrogen valve electrode and an oxygen diffusion cathode. The ion-permeable oxygen electrode may be connected in parallel with the oxygen diffusion cathode during discharge. As shown in Fig. 2, the hydrogen electrodes 20 and oxygen cathodes 21 are separated by oxygen anodes 23. Electrolyte is circulated by pump 29 and hydrogen formed during charging passes out of gas space 23 and is collected in pressure vessel 31 whilst oxygen is separated from the electrolyte in separator 32 and stored in container 34 with valves 38, 39 and 40 closed and 41 open. Sealing liquid 37 equalizes the pressure in the hydrogen electrodes and the oxygen cathodes, the pressure being kept above that in the electrolyte space by reference to manometer 42. Excess pressure in vessel 31 closes float valve 44 and opens valve 38 thus preventing hydrogen passing to vessel 36. During discharge valve 41 is closed and valve 40 is open. The preferred ion-permeable oxygen anode is a foraminous nickel sheet activated by spraying aluminium-nickel alloy on to the surface using a plasma jet and dissolving out the aluminium.

Abstract: 245,147. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Dec. 27, 1924, [Convention date]. Drawings to Specification. Vacuum tubes; R÷ntgen-ray tubes.-A process of making an oxide cathode consists in oxidizing at least part of the surface of a metal core, and surrounding the oxidized core by alkaline earth metal vapour so that oxide of the alkaline earth metal is formed on the surface. The core is preferably tungsten wire, heated in air to about 600‹ C. to oxidize the surface, but may consist of molybdenum, nickel, or alloys. Barium azide is provided on the anode, which is heated in a bulb to a temperature of 1100-1200‹ C. to expel occluded gas, and to reduce and volatilize barium, which is precipitated on the cathode and oxidized, the bulb being evacuated during the heating operation; or the azide may be applied elsewhere inside the bulb. The cathode may be aged by gradually heating the wire to a high temperature and maintaining it at that temperature. Specifications 209,730, 214,262, and 229,622 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also (a) a process in which the barium compound is applied to the oxidized surface of the core and heated, and (b) a process in which the electrodes, mounted on the usual stem, are immersed in barium azide, and barium is brought into contact with the oxidized surface during the subsequent evacuating and heating operation, both by decomposition of the azide on the cathode, and by volatilization from the other electrodes. This subject-matter does not appear in the Specification as accepted.

Abstract: 1279883 Strain gauging MERESTECHNIKAI KOZPONTI KUTATO LABORATORIUM 26 June 1969 [28 June 1968] 32467/69 Heading G1M A force 7 to be measured is applied to a symmetrical frame structure as shown in Figs. 1, 1a which mounts strain gauges in the form of electrical resistors at particular points which are bridge connected as in Fig.2. The structure comprises measuring components 1-4 each mounting a pair of these gauges, a connecting block 5 and parts 6, 8 which are called end members. In operation the forces on the structure twist the components 1-4 into the dotted shapes shown in Fig.1b as that compressive and tensile stresses arise in these components. If the applied force shifts, then in order that the measuring bridge may be independent of this displacement a resistance charge proportional to the force to be measured and to the positioned change of the force must be ensured in branches of the bridge and this is obtained by placing the resistors 18-25 along the tension and compression diagonals of the measuring components as shown in Fig.1b and arranging these resistors in the circuit relationship shown in Fig. 2, a constant electrical potential being applied across either U be  or U ki  and the potential appearing across either U ki  or U be  being calibrated in terms of force. Other forms of frame structure are also described and shown. For Figures see next page
