Abstract: 1,206,480. Semi-conductor devices. BROWN BOVERI & CO. Ltd. 27 Dec., 1967 [29 Dec., 1966], No. 58619/67. Heading H1K. The junction between the emitter zone 11 and the control zone 3 of a PNPN device is shortcircuited at a plurality of locations by alloying a metal layer 16 containing dopants of the same conductivity-type as the control zone to the surface, thus forming a degenerate PN junction between the emitter zone 11 and a recrystallized zone 15 through which tunnelling can occur. As shown the N+ type emitter zone 11 of a Si thyristor is alloyed into an outer P-type zone 3 of a wafer using an Au foil containing 1% Sb. Holes are provided in the foil so that the zone 3 emerges at the surface at several points within the emitter zone 11. A foil 16 of Au containing 1% B is then alloyed to the surface, forming a P+ type recrystallized zone 15 which short-circuits the emitter junction by virtue of the tunnelling action through the degenerate junction between the zones 11 and 15. The wafer is alloyed to a carrier plate through an Al slice. The foil 16 preferably overlaps the area occupied by the emitter zone 11, but it may alternatively comprise several pieces of foil situated only at positions where the emitter junction emerges at the surface. In a further modification the Au/Sb foil may be alloyed to the entire face of the control zone, and apertures may be etched through the resulting emitter layer prior to alloying of the foil 16.

The electrolytic step may comprise deposition of metal, e.g. copper, chromium or nickle, (the grinding step following this), or anodization (the grinding step preceding this). Grinding may be carried out using brush or sponge rollers, or preferably a jet of electrolyte containing abrasive particles, e.g. iron powder, corundum or aluminium oxide, is impinged against the metal surface; pressure being produced, e.g. by a rotary pump or by inclusion of compressed air in the stream. As shown, a metal strip 1 to be provided with a lithographic surface is passed about a rotatable drum 4 partially submerged in electrolyte 7 and closely spaced from counter-electrodes 9. Wet grinding is effected by impinging a jet of abrasive - particles suspended in electrolyte against the strip from slot-die 5; pressure being provided by use of a gas jet 12 intermixed with the abrasive suspension stream 14. Air knives 2, 2a are provided for cleaning the strip. The strip may be connected to the current source via the drum 4 or the die 5. The electrolyte is circulated from the outlet 10 to the electrolyte supply of the die 5. The die may be operated on the air injector principle (see Fig. 2, not shown).

Abstract: 1331728 Carbon fibre reinforced composites HITACHI Ltd 22 Dec 1971 [25 Dec 1970] 59826/71 Heading B3F [Also in Division C7] An aluminium matrix has embedded therein, more than a critical volume ratio (defined herein), of carbon fibres, having a tensile strength greater than that of the matrix, and covered with a thin carbide layer which intimately adheres to the matrix. The fibres are preferaby oriented in one direction in the matrix. The composite may be formed by including in a melt of the matrix material, an element which reacts with the carbon fibres and then immersing the fibres in the melt. Examples refer to heating an alumina pipe under vacuum, inserting the open end of the pipe in the Al alloy melt and using Ar gas to increase the pressure in the vacuum chamber to one atmosphere after filling the pipe. Alternatively a laminate of the fibres, additive element and aluminium may have its ends sealed and then be heated to react the element and carbon. The matrix metal may be alloyed with a non-carbide-forming metal (e.g. Cu).

Filed: 1968-12-23
Abstract: 1,249,147. Automatic equalizer. WESTERN ELECTRIC CO. Inc. 23 Dec., 1968 [26 Dec., 1967], No. 60967/68. Heading H4R. Automatic equalizer for a digital transmission system includes an attenuator network with a fixed pole and a variable zero, feeding an amplifier, including transistors 31 and 32, with a frequency conscious feedback circuit, including components 39 to 44, which provides a fixed zero which coincides and cancels the pole of the attenuator network. The frequency of the variable zero, and the loss of the attenuator, are varied by controlling the resistance of diodes 28 and 52 in accordance with the peak level of the signal at the output of the amplifier. The arrangement is such that the attenuator network is automatically adjusted to build out the line feeding the equalizer to a standard length, which is then equalized by the characteristic of the amplifier.

A shift-control lever 24 for the PRND21 manual range selector valve (not shown) of an automatic transmission on a motor-vehicle, is pivotally mounted at 38 and incorporates a spring pawl 64 one end 70 of which extends transversely therefrom into registry with ratchet teeth 48-58 (Fig. 4), corresponding to the various rough selector positions, formed on the arcuate periphery of an adjacent fixed gate plate 46, movement of the shift lever 24 around the ratchet toothed positions being effected by raising the spring pawl end 70, out of registry with the ratchet teeth, by a flexible strap 78 connected at 80 to a hand-operated twist-grip pivotally mounted on a pin 76 at the upper end of the shift lever 24. In the centre position of the gate, the shift lever 24 is freely movable between the N and D positions, movement into the R or P and 2 or 1 positions being effected by manually raising the spring pawl end 70 by the twist-grip 74 to clear the ratchet teeth as stated above. Movement from the P (park) position can again only be effected by manually raising the spring pawl via the twist-grip, but movement from the R, or, the 1 or 2 positions back to the central N and D position is simply effected by pulling back the shift lever, the spring pawl ratcheting over the teeth 48, 56 or 50 respectively. A transparent arcuate plate or lens 28, mounted in a cover 20, has the PRND21 positions indicated thereon, a position indicating lamp 32, carried by the shift lever 24, directing a light beam on the lens to selectively illuminate the indicated position.

Abstract: 1,271,910. Dyeing hides and leather. DAIWA KASEI K.K. 31 Dec., 1970, No. 61980/70. Heading D1B. [Also in Division C6] In a process for the removal of the grain layer from hides or skins prior to tanning, in which a proteolytic enzyme is allowed to penetrate a skin after which the skin is heated to cause denaturation of the boundary tissue between the grain and reticular layers so that the grain layer may be removed easily, e.g. by water rinsing, the heating and consequent grain layer removal may be effected locally to produce a pattern to facilitate patterned dyeing of the leather. In one example, the grain layer of pig skin is removed locally to produce a pattern and the skin then chrome tanned and dyed with a red, acid dye to produce a light and shade pattern, and in another example steer hide, after similar treatment, is fat liquored and dried and then has the remaining grain layer removed by scraping, after which it is dyed with a yellow acid dye to produce a red and yellow patterned suede leather. Reactive dyes may also be used.

[Also in Group XXXVII] In a motor speed control system functioning similarly to that disclosed in the parent Specification, pole-pieces 70, 71 at the ends of a magnetic member 68 pivoted at 65 are attracted by coils 78, 79 connected in series and shunt, respectively, with the motor armature 60. The member 68 oscillates to control contacts 88, 89 connected to the motor supply circuit, the oscillation frequency being controlled by a pendulum mass 86. When the motor speed exceeds the desired level the torque exerted by the coil 79 on the member 68 exceeds the combined torques due to the coil 78 and a spring 80, whereupon the member 68 tilts clockwise and the contacts 88, 89 are opened, the spring 80 immediately returning the member 68 to close the contacts. The heavier the load on the motor the higher is the oscillation frequency to maintain a given motor speed, the speed being adjustable by a rheostat 96 connected in the circuit of the coil 79.
