Abstract: 1,229,486. Pneumatic emptying of containers. AMERICAN COLLOID CO. 23 April, 1968, No. 19043/68. Headings B8A and B8E. A transport container 1 for granular material is provided with a fluidizing floor 3, the arrangement being such that gas is discharged through the floor at a greater volumetric rate in zones distant from the material outlet 20 than in zones closer to the outlet. As shown, Fig. 2, the floor 3 is formed with apertures into which upstanding gas distributers 30 are fitted, the distributers directing the gas downwardly through apertures 33, 34. The plenum chamber beneath the floor 3 is divided into three chambers to which gas is supplied from a pipe 11 through valves 12<SP>1</SP>, 13<SP>1</SP>, 14<SP>1</SP>. In order to produce a gas flow through the floor zone A which is greater than that through the zone B which in turn is greater than that through the zone C, either the valves 12<SP>1</SP>, 13<SP>1</SP>, 14<SP>1</SP> are adjusted appropriately or the gas distributers mounted in the three floor zones are such as to provide the required different gas flow rates. The container may discharge into a static container, Fig. 3 (not shown), or may be charged from a static container having a similar fluidizing base, Fig. 4 (not shown). In a modification, Fig. 7 (not shown), the fluidizing means consists of hollow elongated chambers provided in their upper surfaces with gas distributers 30 and adapted to be placed on the floor of a container and connected to a source of compressed gas.

Abstract: 1,230,443. Weft patterning in shuttleless looms. GEORG. FISCHER A.G. BRUGG. 24 Oct., 1968 [25 Oct., 1967], No. 50620/68. Heading DIE. Weft guides 1-4, which descend to the same point 82 to present weft to the weft inserter, are swung about individual pivots 6-9 by a slide 26 carrying arms 22-25, a selected one of which is moved under the tail 18-21 of a weft guide by the dobby or jacquard. The slide is operated by a cam 37 and is locked at the end of its stroke by a pawl (not shown) so that the same weft can be inserted on successive picks without the necessity of re-operating the weft guide; the slide is released when a change of weft is indicated. The arms 22-25 are moved under the tails of the weft guides (see Fig. 4) by springs 43 acting on arms 38, when allowed to do so by cams 47, 48 on two camshafts operated by the dobby; either camshaft can hold any lever 22-25 clear of its weft guide tail (as shown), and each shaft has two angular positions, thereby producing four combinations which enable one weft guide at a time to be operated. Springs are interposed in the connections from the dobby to the camshafts, so that the dobby can preselect the next setting, which takes effect when the camshafts are unlocked at the completion of a weft insertion. When a semi-open shed type of dobby is used, the connections from it also include an arrangement whereby partial movements followed by a return to the original position have no effect on the camshafts.

Abstract: 1,231,065. Fluid-pressure servomotor systems. SUNDSTRAND CORP. May 27, 1968 [May 31, 1967], No.25353/68. Heading G3P. In a hydraulic pump or motor unit having a cylinder block 20 rotatable with respect to valve ports 16, 17 and containing pistons reciprocated by a cam 23 which may be adjusted to vary the displacement of the unit, a valve 61 responds to fluid-pressure in one of the ports to adjust a motor 36 coupled to the cam and has a land 105 to prevent hunting due to rapid changes in pressure in the motor 36. When an increase in pressure occurs in the line 18 the valve 61 is displaced to the right against a biasing spring 81 and fluid from the line 18 flows through lines 85 and 66 to the motor 36 to reduce pump displacement. At the same time, the land 105 connects ducts 66a and 74 to regulate the increase in fluid-pressure on the motor 36. A fall in pressure in the line 18 causes the valve 61 to connect the motor 36 to the duct 74. The valve 61 will also be adjusted in response to changes in pump speed when the demand on the system is constant. By supplying the line 18 with fluid at a higher pressure than that normally delivered by the pump the motor 36 reverses the inclination of the cam 23 and the unit functions as a motor.

Abstract: 1,258,502. Zinc-halogen rechargeable electric battery. UNIGATE Ltd. 11 Feb., 1970 [21 Feb., 1969], No. 9548/69. Heading H1B. [Also in Division F1] A halogen storage electrode structure for a rechargeable zinc-halogen cell or battery comprises a substrate 1 of an anodizable metal of Group IV A  to VA of the Periodic Table preferably Ti, Ta, Zr of alloys of two or all of such metals having permanently associated therewith at least one coherent stratum of porous carbon 3. The substrate 1 is preferably in the form of an open mesh such as expanded metal, an apertured or porous sheet. The titanium substrate may have a semi-conducting coating of nitride, mixed oxide or boride. The porous carbon is preferably of particulate or granule form bonded with a synthetic resin powder such as polyethylene, PVC, PTFE, polypropylene, polychloroprene, nylon or rubber nitrile and the mixture of carbon and resin may be bonded to the substrate under pressure. Alternatively, carbon powder may be bonded with the resin dissolved in a solvent using an inert filler such as ZnCl 2 , which is subsequently leached. Quarternary ammonium compounds and silica gel may be added to the carbon. As shown in Figs. 1, 2, the storage electrode may be formed of at least two of the above structures spaced apart by plastics member 5 at the top, and covered with a synthetic resin material 4 in sheet form, which leaves the outer surfaces of the carbon layer 3 free, and leaves one end of the electrode open to permit gas access to the enclosed space between the structures. Spacing members 6, 7 at the bottom are extended to form a gas channel and the members can be snapped together to unite the electrodes in a tight structure over the length of the cells in the battery. The other electrode in the cell or battery is preferably a zinc-bearing electrode comprising the substrate as defined above coated with zinc or a zinc-containing alloy or salt. Liquid zinc halide is used as electrolyte which may contain Hg, In or Ga, polyelectrolytes such as polyvinyl alcohol, thiourea, KCl and HClO.

Abstract: 1,264,603. Vacuum switches. GENERAL ELECTRIC CO. 27 Jan., 1970 [3 Feb., 1969], No. 3905/70. Heading H1N. A vacuum type circuit interrupter has a movable contact with a stroke-length control responsive to the current through the contacts. In Fig. 1 a movable contact 17 is mounted on a conductive operating rod 17a rigidly attached to pivoted cross-bar 26 which is connected via a pull-rod 34 to actuating lever 30. This lever is biased into an "opening" position by springs 39, 32 but is prevented from moving by the latched closing rod 40. When tripped, the cross-bar and operating rod move downwards until the crossbar meets either of the stops 60, 62. Stop 60 is a pivoted lever normally maintained in the position shownby a reset spring 68 so as to thereby limit the opening stroke to a relatively small value. When the interrupter current exceeds a predetermined value, e.g. a short-circuit current, the stop 60 is rendered ineffective, being moved by the attraction of U-shaped magnetic core 72 which partially surrounds the current carrying conductive braid 50. In a polyphase arrangement, Fig. 3 (not shown), the lostmotion connection 41, (41a, 41b) of each phase enables the length of the opening stroke in any one phase to be determined by the stops in that particular phase and not be affected by the stops in the other phases. The arrangement has a solenoid-operated trip and reset mechanism and a common crank-operating shaft. In Fig. 4, a relatively short stop 90, which is ineffective during light current capacitance switching operations requiring a longer opening stroke, is provided for excessive, e.g. short-circuit, currents. The interrupter is tripped either by a push-button 86 or an overcurrent switch 88. In Fig. 5 (not shown), a solenoid operated latch mechanism releases the short stop into its effective position, a reset member (99) being associated with the operating rod.

A selected Group III-V type semi-conductor material is deposited on a substrate by generating a reactant gas which comprises a gaseous mixture of a selected Group III species and a selected gaseous Group V species, this reactant gas including unwanted contaminants, passing this reactant gas over a solid mass of the semiconductor material so as to remove the unwanted' contaminants, and then passing the purified reactant gas over the substrate to deposit thereon the said Group III-V type semiconductor. The reactant gas may be generated by passing a vaporizable halide of the selected Group V species over a heated source material comprising the selected Group III species and/or the selected Group III-V type semi-conductor material, and hydrogen may be used as the transport gas. The Group III-V type semi-conductor material exemplified is gallium arsenide, when arsenic trichloride is used as the halide. In the Figure reactor 10 has reactant gas, inlet 11, carrier gas inlet 12, exhaust outlet 14, and is heated by two separate furnaces 18, and 19 to maintain the desired temperatures, for example 825, 750 and 500-730 C. in the case of GaAs, in the three zones so formed in the furnace. To form the reactant gas, hydrogen is bubbled through AsCl 3  in bubbler 33 and passed through inlet 11 over Ga or GaAs, 16 and emerges into the first zone of the reactor through orifice 17. It then passes of a deposit 49 of GaAs in gap 21 between the furnaces where the impurities are removed, and it then passes on to deposit GaAs on the substrates 22 in support 23. Dopant materials may be introduced into the reactant gas through inlet 47, the dopant being either gaseous, e.g. H 2 S or picked up from a heated solid 48 by a carrier gas. The deposit 49 is formed before the introduction of the substrates by admitting reactant gas through inlet 11 and adjusting the conditions so that GaAs deposits in gap 21. Indium arsenide, gallium phosphide, gallium indium arsenide and gallium indium phosphide are referred to.
