Patent GB-1051720-A (GB)
IPC: H01L29/00
Abstract: 1,051,720. Semi-conductor devices. NORTHERN ELECTRIC CO. Ltd. March 7, 1963, No. 44250/63. Heading H1K. A PN-junction emerging only at the top surface of a wafer is there protected by an insulating film. If there existed a continuous inversion layer under the film on one of the regions this would form a conductive path between the other region and the electrode on the first region (directly if the electrode is on the top surface or via the wafer edge, the condition of which is usually such that carrier pairs are readily generated if the electrode is on the lower surface). To prevent this a zone of lower restivity material is formed in the region liable to inversion and surrounds but is spaced from the junction. Diffused diodes and double-diffused transistors are described in which all contacts are on the upper surface of the wafer or in which one contact is on the lower surface. All devices described are of silicon and have genetic oxide coatings thereon. The diodes are NP devices (Figs. 4, 5, 6, not shown) having a zone 51 of enhanced conductivity in the P-type region 32. The transistors (Figs. 15, 16, 19, not shown) are PNP devices in which the zone of enhanced conductivity is formed in the collector region and to which the collector contact is applied, and an NPN device in which the zone of enhanced conductivity is formed in the base region and to which the base contact is made. It may be desirable to heat a finished device in the presence of water vapour to ensure that an inversion layer is formed over the high resistivity side of a PN junction (except over the anti-inversion zone of lower resistivity) in order to raise the breakdown voltage of the junction.

Abstract: 1,052,983. Clay mineral dispersions; ceramic compositions. MINERALIMPEX MAGYAR OLAJ-ES BANYATERMEK KULKERESKEDELMI VALLALAT. June 5, 1963 [July 11,1962; May 3, 1963], No. 22385/63. Headings C1A and C1J. A colloidal dispersion of a clay mineral capable of being solidified, e.g. bentonite, kaolinite, illite and allevardite, is produced by subjecting an aqueous dispersion of the mineral to a shear rate exceeding 500 sec.-1 until a colloidal dispersion of the mineral is obtained. The aqueous dispersion may be externally heated before or during shearing. When the bentonite is calcium bentonite it is preferably converted to sodium bentonite by cationexchange. Said cation-exchange may be effected during shearing using an electrolyte which releases sodium ions over a prolonged period of time, e.g. water-glass, or a substance which releases all its sodium ions without delay, e.g. sodium carbonate. The dispersion may be recycled through the dispersing apparatus several times. Shearing is preferably effected in a dispersing apparatus having relatively rotatable parallel discs, said discs each having a plurality of annular concentric ribs which are complemental to ribs on the other disc, such that on rotation of one or both of the discs, the ribs define a plurality of shearing gaps, said gaps preferably being not more than about 2 mm. wide. The invention also comprises a ceramic moulding composition comprising a colloidal dispersion of kaolin or a clay containing illite and allevardite produced by the process of the invention in admixture with quartz sand and feldspar.

Abstract: 1,053,438. Fluid-pressure servomotor systems. HITACHI Ltd. Sept. 17, 1963 [Oct. 11, 1962], No. 36610/63. Heading G3P. [Also in Division F1] A speed governing apparatus for a reheat steam turbine plant having high, intermediate and low pressure turbine stages 4, 8, 9, respectively, driving an electrical generator 12 comprises an admission regulating valve 3 and an interstage stop valve 7. The plant also includes a boiler 1, condenser 10, feedwater pump 11, stop valves 2, 6 and a safety valve 15. During normal running regulating valve 3 and stop valve 7 are controlled by turbine speed governors 13, 14 respectively. If the electrical load is removed from generator 12, a relay 16 actuates a solenoid mechanism 17 to override governor 13 and fully close regulating valve 3. Simultaneously a switch 18 is actuated to close stop valve 7. When the speed of the turbines has steadied at a predetermined value a resetting mechanism operates to open valves 3, 7 so that normal control by governors 13, 14 is resumed. The regulating valve control system, Fig. 2 (not shown), comprises an oil operated servopiston 23, controlled by governor 13 through link 21, operating a cam 30 through a rack and pinion 27, 28. A roller 31 following cam 30 is mounted on a lever 32 connected at the other end to a piston 38 running in a cylinder 40. Lever 32 is also connected to regulating valve 65, equivalent to valve 3 of Fig. 1, which is spring biased towards the closed position. During normal running, piston 38 is held in position by a latch 41 but when the load is removed from generator 12 the armature of solenoid 42 releases latch 41 and causes valve 65 to close. The movement of valve stem 33 actuates an electrical switch 44 to send a closure signal to the interstage stop valve mechanism, Fig. 3 (not shown). Should valve 65 fail to close and actuate switch 44, the closure signal is transmitted by switch 43. The signal actuates a solenoid 50, Fig. 3, and latch 54 which causes the interstage stop valve 52, equivalent to valve 7 of Fig. 1, to close under the action of spring 56. A casing 58 controlled by a spring loaded servopiston 61 forms the upper abutment of the spring 56 so that during normal running piston 61 controls the opening of valve 52 in response to movement of governor 14 transmitted through line 63. When the speed of the turbines has fallen to the predetermined value the regulating valve oil distributing valve 25, Fig. 2, supplies pressurized oil to cylinder 40 to reset piston 38 and latch 41. Simultaneously piston 61, Fig. 3, moves downwardly under the action of the spring 60 and the governor oil pressure to enable latch 54 to engage flange 55 and reset the interstage valve control mechanism. If there is no increase in speed of the turbines on removal of the load, the resetting of latch 54 is effected by a switch 64.

Abstract: 1,053,682. Jugs. CONTAINER SUPPLY CO. March 2, 1965 [March 13, 1964], No. 8791/65. Heading A4A. [Also in Division B8] Passage of air through a tubular handle 26, connecting the body 14 and pouring spout 18 of a jug, avoids gurgling due to air-lock during pouring from the jug, the handle joining the spout between the inlet end 20 and the outlet end 24, and a shoulder 48, between the inlet and outlet, reducing the cross-section of the spout and directing outflowing liquid towards the wall 42 and away from the entrance 52 for air. The jug is preferably blow moulded as a plastics unit. For maximum efficiency the initial filling of the jug should be to such level that the air pocket 54 reaches the opening 56 at the same time as the outflowing liquid reaches the rim 58 of the spout when the jug is tilted for pouring.

Abstract: 1,053,833. Moulding building boards. G. J. VAN ELTEN. Jan. 27, 1964 [Jan. 30, 1963], No. 3422/64. Heading B5A. A fleece of wood-wool impregnated with a binder, e.g. cement or magnesite, is laid upon, and preliminarily compressed in, a series of contiguous moving moulds and cut out into lengths as in Specification 902,995, the filled moulds then being stacked and pressed in a pressing device and finally clamped and left, to allow the binder to set. In the embodiment shown in Figs. 1 and 3 the filled moulds are placed on a hydraulically operated press plated 26 and raised until the upper surface of the rims 14 contact and raise plates 17, which are pivoted at 21 to the frame of the device, and which are initially supported by frames 18. The plates in turn support the stack of moulds already introduced into the machine. Spring biased switch member 24 upon which the plates initially rest is thus released which stops hydraulic cylinder 25 and advances, by means of cylinders 20, the plates 17, to push any excess material between rims 13 and the bottom 13 of the preceding mould into the mould cavity, as is shown in Fig. 3 (not shown). Plates 17 are subsequently retracted and the platen 26 further raised to fully compress the material, and to raise the lowest mould above the level of the plates, which are then forwarded to their initial portion to support the stack whilst the platen is lowered to receive a fresh mould. During the compression the stack is restrained by a hydraulically operated platen 15 or by a heavy weight which weight may be retained on the stack during the final curing. In an alternative embodiment shown in Fig. 4 (not shown) each of the plates 17 are connected to the actuating cylinder 20 through a magazine 30 (only one shown) which contains loose side rims 31, the stack of moulds being supported by the plates as before. The platen 26 is raised and side rims 31 pushed on to the mould bottom 13, to laterally compress the material, along guiding means 36, by a cylinder operated member 35. The plates 17 are then retracted and the platen further raised, to compress the material, until the plates may be reintroduced under the stack. The platen is then lowered, the next mould and rims introduced, and the cycle repeated.

Abstract: 1,229,199. Two-part couplings. PAINTON & CO. Ltd. 8 Nov., 1968 [6 Oct., 1967], No. 45902/67. Heading H2E. In a multi-way socket connector for making connections to a tape cable, conductive ribbons of the tape cable backed by resilient arms of plastics material form connector contacts along a side of each socket. As shown, the connector comprises a main body 20 and an insert 22 which is retained in the body 20 by detents 23 engaging apertures 24, both members being made of insulating plastics materials, e.g. nylon or acetal resin. The insert 22 has two pairs of resilient arms 29, 30, and tape cables 5, 51 are bent into an "M" formation and positioned so that the centre sweep of the "M" locates between one of each pair of arms, the free ends of the cables both locating in the central space between arms 30. The tape cables 5, 51 have exposed conductor portions 4 which form contacts for engaging resiliently, under the influence of the arms 29, 30, rigid pin contacts 27 inserted through apertures 26 in the main body. Contact pins 27 may have angular ends to strip away the insulation on the tape cable when first inserted to obviate the need to expose portions 4 of the cable before assembly. Two such connectors are provided, being joined by an integral bridging-piece 21. In a second embodiment (Fig. 5, not shown) a single tape cable is wound round a single elongate comb-shaped member, the "teeth" of which are bifurcated, the outer surface of the cable again being exposed to form a contact portion, the bifurcated teeth providing the required contact resilience. In a third embodiment (Fig. 2, not shown) a tape cable in the form of an "M" is positioned on a member having two parallel rows of resilient arms so that there is provided an elongate channel which can receive the contact-bearing edge of a printed circuit board.

Abstract: 1,230,866. Photo-grammetry. CANADIAN PATENTS & DEVELOPMENTS Ltd. Sept.4, 1968 [Sept. 5, 1967], No.42010/68. Heading G1F. This invention relates to the production of a modified orthophotograph which is such that with an unmodified orthophotograph of the same view it forms a stereo-pair, the modified orthophotograph being produced from the original stereo-pair of photographs by a scanning technique which in effect generates data corresponding to a time orthophotograph, this data then being modified by introducing a change in X- co-ordinates to changes in the Z- co-ordinate in accordance with a predetermined functional relationship, the modified orthophotograph being produced from the modified data. In the figure there is shown part of an apparatus for producing an orthophotograph by photographic reproduction on a film 30 on base-plate 29a. The apparatus comprises universally mounted light projectors from which light passes through a stereopair of diapositives to be focused in the plane of the film 30 and create a three-dimensional image of the terrain represented in the diapositives. This image is scanned by a small aperture 35 in a mask 34 connected to each of the two light projectors by telescopic rods 36 and indexable over the film 30 in both X and Y directions. The aperture 35 is adjusted along the Z-axis together with the baseplate 29a by a hand wheel 48 to bring the aperture to the level of the terrain represented by the three dimensional image as in the production of a time orthophotograph, but additionally as the plate 29a is moved in the Z direction it is also translated in the X direction on rollers 64 by virtue of the provision of a cam rail 62 and follower 61 on the plate 29a, the angle A of the cam rail to the plate being calculated so as to produce the desired modified orthophotograph which with a time orthophotograph of the same view will form a stereo-pair. In some cases the cam rail 62 may be curved. Apparatus is also described in which three diapositives of the same view, two identical are used to simultaneously produce a true orthophotograph and a modified orthophotograph and the technique may also be applied to plating apparatus in which half-silvered mirrors are used to reflect part of the light passing through the diapositives into a binocular system in which the three dimensional image is formed, a floating mark being provided for scanning the image Also described in a cathode ray tube arrangement in which light from scanning cathode ray tubes is passed through a pair of diapositives to photoelectric devices and thence to circuitry connected to a further cathode ray tube on which the desired modified orthophotograph is reproduced and subsequently photographed.
