Title: Vehicle direction signalling system
IPC: B60Q1/38
Filed: 1951-05-04
Abstract: 687,391. Road-traffic signals on vehicles. HOLLINS, R. J. May 4, 1951. No. 10556/51 Class 118 (ii). A direction signalling system for vehicles in which high resistance pilot lamps are in series with signalling lamps has flasher contacts connected in parallel with the pilot lamps so that when said contacts are closed. the signal lamps only light and when the contacts are open the pilot lamps only light. A battery 50 is connected via a main switch 53 (which may be the vehicle ignition switch) to a flasher 60 having three movable contacts 61, 62 and 63 normally making with fixed contacts 66, 67 and 68 respectively. The movable contacts are mounted on a pivoted bar 56 and loaded by spring 58 tending to open the contacts but normally held in the closed position by a resistance wire 65. Pilot lamps 15 and 35 are connected in parallel with contacts 61, 66 and 63, 68 and to terminals 12 and 32 of a selector switch 70, respectively in each case. The resistance wire 65 is in series with contacts 62, 67 and is connected to terminal 13 on the selector switch 70. Signalling lamps 10, 20, 30 and 40 are connected to terminals 11, 21, 31, and 41 respectively of the selector switch 70 which has a pivoted double-sector arm 72 carrying arcuate conductor strips 73, 74 arranged to selectively connect terminal 12 to terminal 11 or 21 and terminal 32 to 41 or 31 according to whether the arm 72 is moved counterclockwise. In whichever direction the arm 72 is turned an incompletely annular conductor strip 76 connects terminal 13 to 14 and completes the circuit for resistance wire 65. Supposing the switch 53 is closed, and the arm 72 moved counterclockwise, current then flows through the low resistance path of the flasher contacts to terminal and thus to signal lamp 10 and to terminal 32 and thus to signal lamp 40. Current also flows through the resistance wire 65 which expands allowing all three flasher contacts to open. The pilot lamps, in series with the selected signal lamps; now carry all the current and since these are of relatively high resistance the signal lamps are extinguished and only lamps 15 and 35 glow. The resistance wire cools and closes the flasher contacts and so the cycle is repeated. A similar action occurs in respect of signal lamps 20, 30, mutatis mutandis, if the selector switch is moved clockwise.

Abstract: 1426539 Integrated circuits TOKYO SHIBAURA ELECTRIC CO Ltd 8 March 1974 [10 March 1973] 10623/74 Heading H1K In a method of making an integrated circuit, a plurality of semi-conductor chips 26, 27 are pressed into a metal substrate 22 through windows in a first insulating layer 23 and a patterned first conductive layer 24, whereafter a second insulating layer 29 of thermoplastic resin is applied to cover the chips, windows are formed in this layer and a second patterned conductive layer 31 if formed to connect electrodes 28 on the chips with the first conductive layer 24. The substrate 22 is preferably of aluminium or can be of gold, copper or indium. The first insulating layer 23 acts as a dielectric and is of polyimide resin or an oxide formed by oxidizing the substrate surface. An electroconductive film is formed on the layer 23, e.g. of copper, gold or aluminium or alloys or laminations of chromium, copper, gold and titanium by vacuum deposition and the first conductive layer 24 is then applied by a photolithographic technique. The chips 26, 27 are then pressed into the substrate with a stainless steel jig whilst the interfaces between chips and substrate are heated to 200-350‹ C. A cushioning layer of polyimide film is interposed between the jig and the chips and later removed. A preformed layer 29 of fluorinated ethylene propylene is pressed in place and heated to melting point. Windows are then formed in this layer by a photo-resist method and the electrode contact layer 31 is applied by vapour deposition and electroplating. The patterned layer 31 may be a lamination of titanium and copper or combinations of chromium, gold, copper and titanium. The chip 26 may be a planar silicon transistor (Fig. 9, not shown).

IPC: H01L21/00
Filed: 1955-04-15
Abstract: 775,616. Processing alloy junction devices. SYLVANIA ELECTRIC PRODUCTS, Inc. April 15, 1955, No. 10972/55. Class 37. An alloy junction is produced by heat-treating a semi-conductor body and an alloy terminal body with a molten flux at a temperature high enough to alloy the two bodies. This treatment may take place during the alloying process or after initial alloying. In an example, indium dots 12 are bonded to an N-type germanium body by heating in nitrogen. The pre-fired unit is then supported on a graphite block 14 in a container 16 and is covered with molten flux, e.g. a 2 to 1 mixture of potassium cyanide and sodium cyanide. The temperature is raised to 590‹ C. by heater 20 and maintained for about 20 minutes; it is then quickly lowered to about 200‹ C. and held there for 40 minutes and thereafter allowed to drop slowly. After this treatment the flux is rinsed off and the unit so formed is boiled in de-mineralized water and wiped dry.

Title: Temporary supports, their prepration and their use in dry dyeing and in dry printing by hot transfer
IPC: G03C1/66
Filed: 1972-03-09
Abstract: 1391012 Flexible coated products SUBLISTATIC HOLDING SA 9 March 1972 [10 March 1971 2 Feb 1972] 11029/72 Heading B2E [Also in Division Dl] A support for dry dyeing or printing synthetic materials by vapour phase transfer comprises a flexible, heat-stable base material carrying in either order at least two superimposed thin organic layers completely or partially covering one of the faces of the material, one being a coloured layer and comprising a dyestuff and/or an optical bluing agent which passes into the vapour state at between 160 and 220C at atmospheric pressure, and a binder which is stable to heat in this temperature range and soluble in the organic solvent present in the ink used to form the coloured layer, and the other layer comprising a protein material which is stable at temperatures up to at least 220C, the layer of protein being discontinuous when it is upon the coloured layer and being non-hardened when it is adjacent the flexible heatstable material. The flexible, heat-stable material may be paper, paper backed with an aluminium foil, or regenerated cellulose film. The dyestuffs may be sublimable azo or anthraquinone dyestuffs or nitroamylamines, styryl dyestuffs, derivatives of quinophthalone, perinones. The binders may be cellulose ethers, especially ethyl-cellulose and mixtures of cellulose ethers containing ethyl- or hydroxypropyl-cellulose. The protein material may be gelatin. The support may be coated over its entire surface with a layer of protein material and a coloured layer thereafter printed thereon or a coloured layer and then a layer of protein material may be printed on the support or the entire surface of the support may be coated with a layer of protein material and then a coloured layer and another layer of protein material may be printed thereon. The layer of protein material applied to the coloured layer may be printed in the form of a regular or irregular design or pattern on only one part of the surface of this coloured layer. After having printed on the coloured layer a layer of protein material sensitised to light, e.g. gelatine dichromate which covers the whole surface of the support, this protein layer is exposed to light whilst at the same time interposing between it and the light source the regular or irregular pattern as a transparency on a plate and the protein material which has not been rendered insoluble then removed by washing. The coloured layer may be of a single colour or it may comprise a regular or irregular design or pattern in one or more colours. Synthetic materials are dyed or printed by placing the support in contact with the material to be dyed, and the whole heated at 180-210C for a sufficient length of time to allow the dyestuffs or the optical bluing agents to vapourise or sublime and penetrate the material to be dyed. The process is suitable for dyeing polyamides, polyesters, polyacrylonitriles in the form of sheets or films or textiles.

Title: Improvements in or relating to methods of manufacturing articles from sheet material impregnated with low pressure synthetic resin
IPC: B32B27/00
Filed: 1949-04-27
Abstract: 671,832. Moulding synthetic-resin-impregnated laminae. ASHDOWNS, Ltd., and JOSEPH, C. B. May 25, 1950 [April 27, 1949], No. 11231/49. Class 87(ii) [Also in Group VIII] In a method of low-pressure moulding a laminated article from layers of synthetic-resin impregnated sheets, in which the sheets are covered on the side thereof which is opposite to that in contact with the mould by a non-adhering sheet and pressure is applied to the laminae, at least in part, through a mobile or flowing porous body in contiguity with the sheet; the article is moulded in a portable mould 17 and each layer of impregnated sheets 14 is formed of overlapping blanks and the non-adhering sheet 15 is formed of over lapping strips whereby occluded air is driven off between the strips during the early stages of the moulding. As described, the mobile porous body comprises lead shot 16 which is progressively introduced in the mould cavity, and if a pressure higher than that provided by the weight of the shot is required a wedge 23 may be inserted in the shot and weights placed on the wedge, or pressure may be applied to the wedge by clamping means. The application of the process to moulding a fireman's helmet is particularly described, the helmet incorporating lugs and loops formed from resinimpregnated glass cloth placed so that they are moulded integrally with the main body. The resins may be polyester resins, e.g. diallyl-phthalate, or compatible co-polymers of polyester resins with or without the addition of a styrene, such resins being referred to as " low pressure resins." The resin may be pre-polymerized to reduce storing time. Other materials than shot may be used for the pressure aplication, e.g. sand, and pressure may be applied externally and transmitted through the sand.

Filed: 1975-03-18
Abstract: 1481396 Photopolymerizable elements E I DU PONT DE NEMOURS & CO 18 March 1975 [18 March 1974] 11242/75 Addition to 1453681 Heading G2C [Also in Division C3]  Images are produced from photopolymerizable elements comprising a substrate bearing a layer of a photopolymerizable composition comprising (i) at least one non-gaseous ethylenically unsaturated monomer, especially trimethylolpropane triacrylate, (ii) an organic polymeric binder, e.g. polymethyl methacrylate or methyl methacrylate/acrylic acid copolymer, (iii) a dimer of a nitroso compound which in dimeric form is a non-inhibitor of free-radical polymerization but in monomeric form is an inhibitor of free-radical polymerization, e.g. nitrosocyclohexane dimer, and (iv) an organic radiation-sensitive free-radical generating system, e.g. 2-ethylanthraquinone, benzophenone/Michler's ketone or a mixture of tris(4-diethylamino-2-methylphenyl)methane with 2-o-chlorophenyl-4, 5-diphenylimidazolyl dimer, there being sufficient nitroso dimer present to provide sufficient nitroso monomer to consume the free-radicals generated in said composition on exposure to actinic radiation; by a process comprising the steps of (a) imagewise exposing the layer to actinic radiation whereby the free radicals generated are consumed by reaction with nitroso monomer dissociating from the dimer so that polymerization does not take place in the exposed layer, (b) deactivating the nitroso dimer, and (c) exposing at least the unexposed area of the layer to actinic radiation causing photopolymerization to take place. Step (b) may be achieved either by cooling to below 10 C in which case step (c) is also carried out below 10‹C using radiation which will not dissociate the dimer at that temperature, or (b) by heating to 80-150‹C to destroy the nitroso compound. It is immaterial whether the first-exposed part of the layer is re-exposed or not, since the radical generating system is used up in the first exposure so that no polymerization takes place in that part on the second exposure. The layer may be coated with a polyvinyl alcohol solution prior to exposure, and may include a u/v radiation absorber, e.g. 4-dodecyloxy-2-hydroxybenzophenone. In Examples, the substrate is a copper-clad circuit board or an adhesive-coated polyester film, and the process is used to produce line images, contour images and gravure plates, and in one case in a negative working pigment toning process.

Convention date, April 20, 1935..[Class 139] An electric clock in which an electromagnet 6 periodically moves a first spring-controlled lever 4, one end of which gives an impulse to a pin 3 rigid with the balance staff 1 and reverse movement being by the hairspring, is characterized in that the make and break of the magnet circuit is caused by a second spring-controlled lever 10 actuated periodically by a cam 9 on a disc 8 rigid with the staff 1, said cam 9 being arranged oppositely to the impulse pin 3 with respect to the staff 1. As this staff swings counterclockwise to the position shown, the pin 3 on disc 2 passes to below the end of the armature lever 4 and the cam 9 actuates the blade 11 on lever 10 to press contact 13 down on to contact 14. The consequent energization of electromagnet 6 causes lever 4 to rotate the balance staff 1 further counterclockwise. Cam 9 wipes past blade 11 and spring 17 breaks the contacts. The staff 1 is then returned by the hairspring.

The pressure and temperature are maintained so that where the body is lyophilic, the liquid mixture enters the finer pores and where the body is lyophobic, the liquid mixture enters the coarser pores. The vapours are condensed in cooler K, and a portion of the condensate may be recycled to the porous body at point 6. The components of the mixture having higher boilling point are withdrawn at 7. The pressure range of the carrier gas is ascertained by a specified mathematical formula. Upper and lower fine-pored covering layers 2 and 3 rest directly against the porous body 1. If the liquid mixture does not wet the porous body, then a carrier gas is not required, and the body is maintained at a temperature such that vapours of the more volatile component(s) are formed. The use of metal and of carbon porous bodies is mentioned.
