A piezo-electric crystal h of the bender type is attached to the wire a within the frame f, which is felt lined. The crystal is connected to a valve amplifier through terminals l<SP>1</SP>, m<SP>1</SP> in a strip j carried by lugs i<SP>1</SP> ona thin brass plate i cemented to the crystal. The crystal and amplifier are designed to respond to vibrations of high frequency such as would be caused by the frictional contact of a broken sliver with the wire a and to be unaffected by vibrations of low frequency such as unwanted mechanical and sound vibrations. The controL voltage yielded by the valve amplifier may be used to operate an indicator or a relay for stopping the frame. In place of a crystal, the detector may comprise a. magnetic core and electric winding thereon, sus- . pended by a central mounting from a thin plate p, Fig. 5, of magnetic material with ends bent at right angles near the ends of the core to form short air gaps in a magnetic circuit. The vibrations to be detected will flex the plate to vary the length and hence the reluctance of the air gaps.

[Class 73.] Apparatus for making packets for cigarettes &c. by assembling single packets in pairs on edge and applying an adhesive band to their adjacent longitudinal sides comprises means for receiving the packets as they leave the packing machine in flat position, separating a pair, turning them on edge, and feeding the pair to an adhesive-applying station, after which the band is applied. The packets are fed from the packing machine along a track b and are transferred in pairs by a pusher a to a position above a pair of tiltable plates c, d; a weight-actuated stop is provided to prevent the operation of the pusher a in the absence of a pair of packets. The tiltable plates c, d are mounted on parallel shafts 26, 27 operated by rack and sector mechanism to turn each of the packets through a right-angle.

The pair are transferred along the channel h by a pusher k and thence along a channel m by a pusher n. During this movement, the top edges of the packets are gummed by a rolling sector 43, and, in order to leave a free space o between the packets already gummed and those about to be gummed, the travel of the pusher n is greater than the length of the packet.

As the saw unit moves with the board, the engagement of the roller 65 in a cam recess 71 lowers the saw 72 to cut a predetermined length off the board and then raises the saw again. Subsequently, an adjustable sloping abutment 73 raises the forward end of the board clear of the abutment 68 and a weight 70 and cord 69 can then return the saw unit to its initial position, the recess 71 being covered by a masking arm 75 during the return movement. A cord 79 connects the saw unit to a lever 81 and, as the unit returns, the lever is pivoted to raise the rear end of the cut board so that the next length to be cut can pass beneath it.

Abstract: 967,292. Gallium arsenide tunnel diodes. GENERAL ELECTRIC CO. Sept. 22, 1961 [Sept. 26, 1960], No. 34014/61. Heading H1K. A tunnel diode comprises a gallium arsenide body containing a narrow PN junction between degenerate P and N type regions having uncompensated acceptor and donor concentrations respectively greater than 10<SP>18</SP> atoms/c.c. but a total concentration of the rapidly diffusing impurities copper, silver and gold less than 10<SP>15</SP> atoms/c.c. A typical device is prepared from a wafer of gallium arsenide doped to P- type degeneracy with cadmium by heating it in potassium cyanide at 650‹ C. for 30 hours. After removal from the cyanide and cooling the wafer is placed on an assembly consisting of a gold wire 9 (Fig. 2), a layer of indium-cadmium solder, a plate 2 consisting of an alloy of 54% by weight iron, 29% nickel, 17% cobalt, and a layer of indium-cadmium containing 4% by weight cadmium, and heated in hydrogen at 450‹ C. for 20 seconds. The PN junction is then formed in the upper surface of the wafer by heating in contact with a tin-sulphur alloy pellet 7 for 45 seconds at 500‹ C. in hydrogen subsequently the junction area is reduced by chemically or electrolytically etching to the form shown in Fig. 2. In an alternative method the device is first made using commercially pure gallium arsenide and subsequently treated to reduce the amount of copper, silver and gold to the desired level. Sodium cyanide and various halides and sulphides may be used in the above process in place of potassium cyanide but where sulphides are used the surfaces of the wafer must subsequently be ground or etched away to remove any sulphur diffused in during the process.

Abstract: Hydrocarbons are subjected to moderate heat treatment with steam in presence of catalysts, and the mixture so obtained is submitted to further heat treatment admixed with air in presence of catalysts. Oxides of carbon may be removed from the resulting product by known means, and the quantity of air employed may be regulated to yield hydrogen and nitrogen in the proportions of three to one.  The chamber in which the first stage of the process is conducted is preferably of annular cross-section and constructed of high-grade steel and may be provided with a filling of metal fragments.  The air required for the second stage may be pre-heated, obviating the necessity of heating the second reaction chamber.  The temperatures used in the two stages may be 850 DEG  C. and 950-1200 DEG  C. respectively, and a nickel catalyst may be employed in each stage.

Title: Improvements in color photography

Filed: 1946-11-19
Abstract: 626,979. Colour photography. REPUBLIC PICTURES CORPORATION. Nov. 19, 1946, No. 34262. Convention date, Nov. 19, 1945. Drawings to Specification. [Class 98 (ii)] A photographic element for use in making transparent colour prints which has two layers of emulsion, as of gelatin, on one side of a base such as cellulose nitrate or acetate, each layer containing silver halide and a colour former, is characterised by the emulsions not being colour sensitised, whereby the light sensitivity of each layer is the normal sensitivity of the silver halide. The layers may be exposed from opposite sides of the element to colour separation negative records such as blue-green and orange-red printing negatives, colour developed to produce appropriate coloured images in both layers simultaneously, fixed and bleached to provide a positive colour print. Penetration of the printing light from one layer to the other may be prevented by effecting the exposures by ultra-violet light which has low penetrating power, or by use of a removable dye such as quinoline yellow in the emulsion layers or in a separate layer between them. Alternatively, such separate layer may contain silver particles produced as by exposure and development of light sensitive silver halide. A third colour image may be applied to the two colour print by imbibition. In a modification the element is provided with a further emulsion layer containing silver halide and a colour former between the other two layers, this layer being colour sensitised, for example to red light, and this layer is exposed first, from either side by red light which does not affect the other two layers to a third colour separation negative. The colour former in the colour sensitised layer may have no relationship to the colour sensitivity of that layer.
