Abstract: 1,060,509. Semi-conductor devices. SIEMENS-SCHUCKERTWERKE A.G. Sept. 13, 1965 [Sept. 11, 1964], No. 39060/65. Heading H1K. A magneto-resistive field plate consists of semi-conductor material rendered anisotropic by the inclusion in or deposition on the semiconductor 1 of conductive strips or needles 2. It takes the shape of a crescent, and when rotated in its plane about an axis 8 into the air gap between the arcuate facing poles 7 of a magnet moves into a magnetic field perpendicular to its plane. The combined effect of the anisotrophy and the crescent shape is to make the relationship between angular displacement and resistance linear, so that the device shown is a rotary variable resistor. For potentiometer applications there is a centre-tap electrode 5 in addition to the terminal electrodes 3 and 4. Fig. 2 depicts a modified field plate consisting of two crescents joined together at one end and with terminal electrodes at the respective.free ends of the two crescents. The preferred semiconductor materials are indium antimonide, indium arsenide and gallium antimonide and the inclusions may be strips of silver or copper or needle-like crystals of conductive nickel antimonide, chromium arsenide or gallium-cobalt.

Abstract: 1,226,565. Spray producers. WALTER C. BEARD, Inc. 1 April, 1968 [7 April, 1967], No. 15478/68. Heading B2F. [Also in Division Fl] In a dispensing device for a valved pressurized container, having a discharge orifice in communication with an internal passage adapted to be associated with the valved dispensing passage of the container, a pin is adapted to close the discharge orifice, the pin and orifice being associated by resilient means which are deflectable by the pressure of the product to effect relative axial movement of the pin and orifice to open the orifice when produced under pressure is present in the internal passage. Fig. 1 shows a pressurized container 22 having a discharge orifice 43 formed in a resilient member 42 of rubber or a plastics material such as ethylene vinyl acetate, the orifice 43 being normally closed by a pin 40 so that clogging of the orifice and the conduit 36 extending between the valve and the orifice by dried and hardened product is prevented. When the valve is opened, by pressing on top of the spray head 20, a shoulder 31 of a spring-pressed plunger 23 is disengaged from a gasket 29, and product passes via a slot 35 and the conduit 36 and thence through the discharge orifice 43 which is opened by by the pressure of the product flexing the resilient member 42 away from the pin 40. In the modification shown in Fig. 5, the discharge orifice 49 is formed in a preferably rigid plate 48, and the pin 51 which normally closes the orifice is of resilient material and carried by a resilient diaphragm 50 which, as shown, is flexed by the pressure of the product to withdraw the pin from the orifice. An air escape hole 52 is provided behind the diaphragm 50. In another arrangement, Figs. 7 and 8, the discharge orifice is formed in the resilient top 73 of a cap 61 and co-operates with a rigid pin 67 on a stem 59. The cap may be integral with the stem. The product passes to the discharge orifice via passages 60, 65 annular chambers 64, 72, and a swirl chamber 69, which may be substantially circular or elliptial, formed between an annular wall 68 of the cap 61 and a raised portion 66 of the stem 59. One or two swirlinducing entry slots 70 are provided in the wall 68. One or both of the annular chambers 64, 72 may be omitted.

Abstract: 1,227,526. Feeding sheets. LITTLEWOODS OF LIVERPOOL Ltd. 19 Feb., 1969 [22 Nov., 1967], No. 53047/67. Heading B8R. Apparatus for feeding sheets or cards comprises, as a unitary structure, a vacuum roller mounted on a driven shaft and stationary coaxial valve means on the shaft controlling the application of vacuum to the roller. The apparatus is particularly suited as the vacuum roller lying between two conveyers of a documentsorting device as disclosed in Specification 1,227,527. The roller 12, Fig. 1, is provided with a plurality of longitudinal bores 18 arranged in an arc, each bore communicating with suction nozzles or ports 19 along its length, the valve means is stationary, and comprises a manifold 10 having an arcuate groove 14 in its inner face 13 communicating with a duct 15 leading to a vacuum pump, and a manifold plate 11 having an arcuate slot 16 and a radial slot 17 venting to atmosphere. A further plate 20, rotating with roller 12, and provided with bores 21 corresponding to the bores 18, may be provided for easy replacement and to reduce wear on the roller 12 and plate 11. The groove 14, slot 16 and bores 18, 21 are all at the same radial distance from the roller shaft (not shown), but the slot 16 subtends a smaller angle at the shaft than the arc of bores 18, 21. The preferred arrangement involves five bores 18 and a slot 16 equivalent in arcuate length to three bores; any one bore will pass through three stages during rotation of the roller, at one of which a vacuum will be applied through slot 16, at the second the vacuum will be held while the bore is opposite the manifold plate 11 between slot 16 and slot 17, and at the third, the vacuum will be released through slot 17 (see also Fig. 2, not shown).

Abstract: 1,234,673. Ceramic laminates. INTERNATIONAL BUSINESS MACHINES CORP. 26 July, 1968 [22 Aug., 1967], No. 35712/68. Heading B5N. [Also in Division H1] A method of forming a monolithic structure e.g. a micro-electronic device from a plurality of sheets consisting of particulate material e.g. ceramic material, dispersed in a binder e.g. polyvinyl butyral, comprises placing the sheets over a die cavity, effecting relative movement between the die cavity and a die member adapted to co-operate with the cavity to cut a portion of the stacked sheets to the cross-sectional shape of the cavity and force them into the cavity, and laminating the cut sheets into a monolithic structure in the cavity by maintaining a high pressure on the cut sheets between the die member and a bottom surface of the cavity. Specified ceramic materials are alumina, zircon, aluminium silicate, zirconium dioxide, titanium dioxide, magnesium silicate, barium titanate and mixtures thereof. In the example, a monolithic structure containing a plurality of spaced micro-electronic circuits is made by feeding dried ceramic films 20, 21 and 22 past punch presses 29, 32 and 43 respectively, the punch presses forming perforations 42 along the longitudinal edges of the films, through holes 30 and 33 to allow subsequent electrical connection between the spaced semi-conductor patterns at different levels and semi-conductor receiving cavities 31 also being formed by the punch presses, electrode paste e.g. of tungsten, molybdenum, platinum, palladium, silver or alloys thereof being applied to the films by silk-screen printers 34, 35 and 36 to form circuit patterns 37, 38 and 39 thereon, a portion of the electrode paste being squeezed into the through holes and optionally into the cavities, the films being aligned and fed by sprocketed rollers 40 and 41 cooperating with the perforations 42 to a press which cuts the films, presses the cut sections thereof into a monolithic structure and forms terminal holes therein, the resultant product being sintered to burn off the binder, vitrify the structure, fire the screened electrodes and embed contact pins embedded in the terminal holes. The press 51 has a body portion with a cavity therein defined by walls 52, a lower die 53 having a plurality of vertical channels 54 with a plurality of punches 55 slidably held within the said channels and an upper die 56 provided with a plurality of channels 57 in registry with and for reception of the punches 55. In operating the press, the films 20, 21 and 22 are stacked across the mouth of the cavity and the upper die 56 lowered to cut through the films, the punches being simultaneously raised to form the terminal holes through the films and to force the punched material into channels 57, the upper die continuing its downward movement until the punched films contact the lower die 53 and full laminating pressure is applied, the lower die then being raised to eject the resultant monolithic structure from the cavity.
