Abstract: 1,271,243. Integrated circuits. TEXAS INSTRUMENTS Inc. 8 July, 1969 [8 Oct., 1968], No. 34323/69. Heading H1K. A method of providing multilevel interconnections between the satisfactory integrated circuits 12-22 of a system spaced on a surface of a substrate 10 comprises forming a first group of spaced elongated conductors 4-44 on the substrate surface adjacent to but spaced from the integrated circuits, each of said first conductors having its ends terminating in connection areas 26-30 with the remaining portions of the conductor defining a first conductor area, then selectively applying a layer 50 of insulation over these first conductor areas and substrate surface, then forming a second group of spaced elongated conductors 60-64 extending transversely to the first conductors over this layer of insulation, each of said second conductors having its ends terminating in connection areas 32 and selectively overlying and connected to respective ends of the first conductors, and finally forming a third group of spaced elongated conductors 70-78 according to an individually calculated pattern for the circuit system in the connection areas to interconnect satisfactory circuits as required via satisfactory first and second conductors. Unsatisfactory circuits and conductors are not connected in the system. To calculate the pattern of the third group of conductors, the integrated circuits and conductors of the first and second groups are tested and those which are satisfactory are selected for interconnection, the testing and interconnection pattern calculations being performed by computer. Layers 34, 36 of conductive material to form earth buses for the circuit system may be applied prior to the application of the layer 50 of insulation. The provision of power supply conductors 59 may also be carried out as a separate step of the method. The layer 50 of insulation, which is generally silicon oxide, may be provided with a surface layer of silicon nitride to provide protection against the etchants used during subsequent processing steps.

Title: Apparatus for conveying solid substances in pipelines
IPC: B65G53/30
Filed: 1960-10-14
Abstract: 948,466. Conveying solids in liquids. RUHRGAS A.G. Oct. 14, 1960 [Oct. 15, 1959], No. 35345/60. Heading FIR. Particulate solid material is conveyed in a pipeline in a liquid which is gaseous at the conditions prevailing at the exit end of the pipeline and which is compressed to liquefy it before or after mixing with the material to be conveyed, the gas being maintained in the liquid state by pressure in the pipeline. With a long pipeline pumping stations may be spaced along its length to maintain the pressure. Pressure release means at the exit of the pipe permit the liquid to expand and so return to the gaseous state and the solid material is separated from the gas. The gas may be returned to the entrance of the pipeline in the gaseous state or be recompressed and returned as a liquid; a separate return pipe or the main pipeline may be used. Expansion of the liquid may take place in an expansion chamber or machine; it may take place in the extreme end section of the pipeline, in which case conveying in this section may be partially pneumatic.

Title: Improvements in or relating to mounting arrangements for the transducer heads of a magnetic drum storage device
Inventor: WOODING HARRY
IPC: G11B5/48
Filed: 1958-11-04
Abstract: 899,138. Magnetic recording. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Oct. 29, 1959 [Nov. 4, 1958], No. 35411/58. Class 40 (2). In a head assembly for the transducing heads of a magnetic drum storage device, a mounting block 3 comprises two members 6, 7 bolted together at their ends and so shaped that a plurality of vertically disposed, horizontally extending, slots are provided in the block, each of which slidably accommodates one arm of an L-shaped support 9, the other arm resiliently holding a magnetic head by means of a flat spring 11. A tool 20 has an eccentric projection 21, and may be passed through a hole in the member 7 so that the projection engages a vertical slot in the support 9; rotation of the tool causes the support to slide thereby adjusting the magnetic head in a substantially circumferential direction. Nylon locking screws 23 hold the support in its adjusted position. A screw 24, passing through the mounting block, engages a slot in the rear of the head which may thereby be adjusted in a substantially radial direction. As shown in Fig. 1, adjacent mounting blocks may be disposed close together, the respective sets of supports 9 being inserted from the left and from the right. A second flat spring may be provided at the rear of spring 11 to improve the resilient mounting of the head on the support.

Title: Improvements in or relating to the manufacture of wave guide attenuators
Inventor: PEARCE GRAHAM
IPC: H01P1/22
Filed: 1954-12-07
Abstract: 823,367. Waveguide attenuators. PAINTOR & CO. Ltd. Dec. 7, 1955 [Dec. 7, 1954], No. 35461/54. Class 40 (8). The resistive element of a waveguide attenuator comprises a plate which has on its surface either a plurality of separate areas of resistance material insulated from one another or a number of separate non-resistive areas surrounded by resistance material, the element being formed by metallizing a flat sheet of non-conducting heat-resisting material on at least one side with an adherent film of resistive material and subsequently subjecting the film to a photo-etching process to remove at least some of the resistive material from selected parts of the film. A flat circular sheet of non-conducting material such as glass, glass mica or ceramic is chemically cleaned and a metallizing solution is then applied to one face of it by a spinning method as described in Specification 689,795, [Group XXXVI], in which the sheet is rotated on a spinning table enclosed in a thermostatically temperature-controlled cabinet and a metallizing solution is evenly distributed over the surface of the sheet. The metallizing solution as described in the above Specification comprises gold, platinum and rhodium. The coated sheet is then fired at a suitable temperature, i.e. about 450‹ C., to decompose and burn away the organic constituents and leave an adherent film of alloy. Such a film may have a resistivity of the order of 40 ohms per square inch. The metallized sheet is then coated with a layer of light-sensitized photo engraving glue preferably by a spinning method and is allowed to dry. The sheet is then exposed to light through a photographic negative of the required resistance pattern and then washed. The glue image is then hardened and converted into a resist by baking for 20 minutes at a temperature of 280- 300‹ C. The sheet is then etched by immersing it into a solution comprising for example 2 parts by weight of bromine and 98 parts of amyl lactate which removes the film from the sheet in those places not protected by the glue image resist. The sheet is then finally fired at about 600‹ C. to burn off the glue image resist. Alternatively the resistive element may be formed with a series of resistive patches on the surface. If desired a larger sheet of material may be used and a plurality of resistive elements may be formed in one operation. The attenuator may be pivotally mounted within the waveguide or if it is mounted in a slot and adapted to be slidable in a direction perpendicular to the length of the guide there may be conveniently provided a corresponding slot in the opposite wall so that a larger resistive element may be used. Specification 775,453 also is referred to.

Abstract: 1380667 Humidity sensor ASAHI GLASS CO Ltd 25 July 1973 [25 July 1972 27 March 1973] 35477/73 Heading G1S A humidity sensor for detecting moisture condensed on a plate of electrically insulating material such as glass comprises a pair of inter-digitated electrodes, Fig.1, printed on the glass and used for detecting the change of electrical resistance of the surface between the fingers. The electrodes are printed from a pasty conductive composition of glass frit and gold, palladium, platinum, or a metal oxide such as ruthenium oxide, and baked on an undercoat consisting of hydrophilic resin, water glass or a metal oxide containing TiO 2 , Cr 2 O 3 , SnO 2  &c. The sensor and the gaps between the electrodes is then coated over with an aminoorganofunctional alkoxysilane or an organosilicon compound reinforced by a reactive compound, many examples of which are given, and the composition is then cured by ageing or heating. The coating repels small amounts of water but larger  amounts permeate the coating and make it electrically conductive so that it is useful as a switch i.e. either on or off. A sensor per se manufactured in this way has a stable resistance value over long term operation and may be used to operate a demister, Fig.5 (not shown) or a blower motor.

IPC: H01J5/40
Filed: 1958-11-05
Abstract: 881,631. Sealing metal through glass or ceramic. GENERAL ELECTRIC CO. Ltd. Oct. 29, 1959 [Nov. 5, 1958], No. 35540/58. Class 36. One or more metal wires 1 or similar conductors are each surrounded by a closely-spaced metal cylinder 6 and sealed through a glass body 5, the metal cylinder extending through one surface of, and part way into, the glass body. The latter may be sealed into an aperture in a glass, metal or ceramic wall 2 either during or after the sealing of the wire into the glass, the various components all having matched thermal expansion coefficients. The purpose of the seal is to avoid formation of cracks, where the wire enters the glass, due to bending of the wire, and a further sleeve may be similarly inserted part way through the opposite surface. Preferably, however, a flange 3 is formed on the wire 1 instead, in which case the seal may be made by placing the flanged wire in a hole in a graphite plate 4, placing a sintered glass pellet 5 around the wire and the sleeve 6 thereon and heating. Several seals may be made together in similar fashion by arranging the assembled components in a centrifuge within a furnace. The wire and cylinder may be copper and the glass that disclosed in Specification 817,636. Specifications 567,521, 629,742 and 851,068 also are referred to.

Title: Continuous treatment of fibres
IPC: D06B3/02
Filed: 1953-12-22
Abstract: <PICT:0737078/IV (c)/1> In a process for treating textile (e.g. cotton) fibres for the removal of natural waxes and the like, the fibres are carried as a suspension in a stream of air in a conduit 10, whence they impinge on a continuously rotating hollow roller 15, having a foraminous surface and means for extracting the incoming air from within the roller, so that the fibres form a thin layer on the surface of the roller; the layer which should not weigh more than 3 grains per square inch is then taken off between rollers 31, 32 and is sprayed with a plurality of high-velocity streams of hot caustic soda solution from the manifold 37, thus producing violent agitation of the layer, and the resulting liquid stream passes down a vertical column 35 over a succession of baffles 36 into a tank 40.  The violent agitation of the fibres produced by the spraying with caustic soda solution brings about a scrubbing or scouring action which loosens and partly removes the impurities located on the outer surface of the fibres.  The fibres collect in the tank 40 and remain there for several minutes, during which time the interaction between the liquid and the fibres is completed, and then pass out in a thick layer or batt over a slowly-rotating perforated drum 42, the excess liquid draining into tank 46.  The batt then passes between mangle rollers 50, 51 and past a washing stage comprising manifolds 55 and rollers 57, 58 into a bleach tank 60 containing sodium hypochlorite solution. The batt issuing from this tank passes over perforated drum 65 and between rollers 70, 71 to a neutralizing stage wherein dilute acid is sprayed on to the material from manifolds 75, and thence between rollers 76, 77 to a final washing and drying stage. U.S.A. Specification 2,365,793 is referred to.
