Abstract: 1,098,889. Sensing cards. FERRANTI Ltd. Sept. 12, 1966 [Sept. 17, 1965], No. 39774/65. Heading G4M. A coded card which carries areas of magnetic material is read by an array of reed switches, the switches are normally held in one state by associated local magnetic fields e.g. from permanent magnets, and the insertion of the card modifies the configuration of selected magnetic fields so that the states of the corresponding switches are altered. The card may be formed from discrete areas of magnetic material forming magnetic shunts or flux concentrators and enclosed between sheets of non-magnetic material. Alternatively the card may contain a sheet of magnetic material which is perforated at selected positions. A microswitch may be actuated when the card is correctly inserted, and this switch may be used to energize electromagnets producing the local magnetic fields.

Title: Improvements in and relating to articles comprising or consisting of cellular polymeric material and the manufacture thereof
Inventor: MARSDEN PETER DAVID
IPC: C08J9/36
Filed: 1962-10-29
Abstract: Cellular polymeric material in the form of separate and/or interconnected filaments and/or strands may be further expanded by heating to a temperature which is above 85 DEG  C. but below the softening temperature of the polymeric material.  The polymeric material contains a vaporizable expanding agent, absorbed in some way, which will be released into the cell spaces at temperatures above 85 DEG  C. Suitable polymeric material is polystyrene or a styrene interpolymer containing at least 50% by weight of styrene and the heating of the material may be by direct contact with a liquid or vapour having no solvent action on the polymer, e.g. water or steam. The filaments and/or strands may be crushed before the further expansion to provide a finished product which has a finer cell structure and is more flexible. Articles may be produced from the filaments and/or strands either alone or in a combination with cellular or non-cellular materials, by direct bonding.  Suggested articles are bottle sleeves, decorative tiles, building panels and packaging materials.

Abstract: 1,133,416. Slide projectors. AGFA GEVAERT A.G. Sept. 8, 1967 [Sept.10, 1966], No.41097/67. Heading G2J. Slide changing mechanism for a projector having vertically or horizontally stacked slides, comprises a slide pusher 2 having two slide engaging teeth 5a, 5b one behind the other on a common balance arm pivoting on spindle 3 mounted on member 2, the arrangement being such that if a thicker slide rides over and so depresses the first tooth 5a, the second tooth 5b is thereby raised sufficiently to engage the slide for the slide changing movement of member 2. An extension of the foremost tooth 5a acts as a stop to limit its extension under gravity into the slide shaft 1. A second spindle 7 carries a further single tooth in line with the tooth 5a. The balance arms are spring-loaded for horizontal stacking.

Title: Improvements in or relating to methods of producing objects of quartz glass
IPC: C03C1/02
Filed: 1962-10-31
Abstract: In the manufacture of an object of quartz glass, natural crystalline quartz is brought into contact with a molten cuprous compound and from the treated quartz an object is made by known methods, such object having a high absorption in the waveband at and below 1850 <\>rA, but a high transmission in the waveband above 2100 <\>rA. Preferably, the quartz crystals are introduced into a bath of molten cuprous oxide or chloride at a temperature greater than 1000 DEG  C. for a time sufficient for the exchange of Li ions by Cu ions. The bath is heated in a nitrogen atmosphere to prevent oxidation. After treatment, the quartz crystals may be heated with dilute acid to remove excess copper compound before melting to form the quartz objects.  Alternatively, a cuprous compound may be added to the quartz crystals and the materials heated for an adequate time at a temperature below the melting temperature of the quartz but above the melting temperature of the cuprous compound to permit the copper ions to diffuse into the crystals.

Abstract: 1,262,393. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 22 Aug., 1969 [30 Aug., 1968], No. 41980/69. Heading H1K. [Also in Division G4] Identifying code marks are etched on pieces of semi-conductor material during an early manufacturing stage of a device to be constructed on the material. The code marks may comprise concentric rings which are scanned by a row of photodetectors transverse to the direction of movement of the material, an annular code track which is scanned by a rotating mask and a single detector, or a series of marks having selected spacing to produce different frequency outputs from a detector, the marks being etched in the kerf area between individual wafer areas. In the latter case a clock is gated on by a first detected frequency f3 and each occurrence of a detected code frequency f1 or f2 in coincidence with a clock pulse shifts the corresponding code bit into a shift register. A further frequency f4 at one end of the code indicates the direction of feed and controls the order in which the shift register contents are gated out.

Abstract: 932,742. Fire-extinguishing. PYRENE CO. Ltd. Nov. 30, 1961 [Dec. 7, 1960], No. 42129/60. Class 47. Apparatus for spreading foam on aircraft runways comprises a wheeled vehicle 1 on which a number of generators of mechanical or air foam are mounted so as to be adjustable from a stowed position in which they are close together and substantially parallel with their foam tubes extending rearwardly to other positions in which they are spread out fanwise to deliver between them a foam strip of width greater than that of the vehicle. The latter also carries members 24 mounted to move outwardly on each side of it to support the generators when spread out fanwise. As shown, the trailer 1 carries a central fixed air-foam generator 2 and four lateral generators 3 which are each of the kind described in Specification 842,461, and have a foam-generating head 4 connected to a foam tube 5 on the end of which is fixed a spreader 6 adjustable both around the generators and in elevation. The trailer carries an internal-combustion engine which drives a pump 9, the suction side of which is connected to an inlet pipe 10 for water. The latter is connected by a hose to a water tank, which may be carried on the same or a separate vehicle. The discharge side of the pump 9 is connected by a pipe 12 to a manifold 13 which feeds the generators through pipes 14. A pipe 15 branches from the manifold 13 to supply water to an inductor 16 the low-pressure point of which is connected to a supply pipe 17 for a foam stabilizing solution which may be carried on the same vehicle as the water tank. This solution is thus drawn into the inductor 16 which discharges through a pipe 19 into the pipe 10. Each of the lateral generators 3 swivel about a vertical axis, the pipes 14 making a swivel joint with a short pipe 21, and are supported by two wings 24 joined by vertical hinges 25, to a fixed central part 22 of a supporting bar 23. The outer ends of the wings 24 are supported by cables 26 which extend from the top of a stanchion 27. When the apparatus is not in use the generators 3 and the wings 24 lie parallel to one another and may be secured by straps. In use the generators 3 are spread out fanwise by rolling along the bar 23 on rollers which when the generators are in position are clamped by hooks on the bar 23.
