IPC: C08J7/056
Filed: 1967-11-30
Abstract: 1,168,171. Coated polyester film. E. I. DU PONT DE NEMOURS & CO. 30 Nov., 1967 [24 April, 1967], No. 5422/67. Heading B2E. [Also in Division G2] Subbing-coated oriented polyester film is prepared by giving the surface of an oriented polyester film an adhesion-improving treatment by electric discharge, a flame or ultraviolet light, surface oxidation or the action of an acid, coating the treated film with a 1 to 15% aqueous dispersion of a copolymer of an aliphatic unsaturated carboxylic acid and at least one other ethylenically unsaturated monomer, the copolymer having a Second Order Transition temperature in the range -30C. to +30C., drying the coated polyester film, and heating the copolymer coating on the polyester film at from 120C. to 180C. for at least seven seconds to cure the copolymer. The copolymer coated film surface may be overcoated with a hydrophilic colloid layer, e.g. a light sensitive gelatin-silver halide emulsion. The copolymer may be of (a) 70 to 90 percent by weight of an unsaturated ester of a monocarboxylic acid where the alcohol component of the ester has no more than four carbon atoms, (b) 7 to 20 percent by weight of an aliphatic polyfunctional compound containing at least two sites of carbon to carbon unsaturation where at least one of the sites is represented by an allylic or vinylic group, glycidyl acrylate, glycidyl methacrylate, methacrylate esters wherein the alcohol portion of the ester is hydroxy substituted, or fumaric acid, and (c) 3 to 30 percent by weight of itaconic acid, fumaric acid, acrylic acid or methacrylic acid, with the proviso that when (b) is fumaric acid (c) is itaconic acid; (a) 70 to 90 parts by weight of vinyl acetate, (b) 7 to 40 parts by weight of a lower alkyl acrylate, and (c) 3 to 30 parts by weight of itaconic acid, fumaric acid, acrylic acid or methacrylic acid; (a) 70 to 95% by weight methyl or ethyl acrylate, (b) 3 to 30% by weight diallyl phthalate or divinylbenzene and (c) 2 to 20% by weight itaconic acid; or as described in Specifications 1,146,215, 1,140,651, 1,125,460, 718,422 and 688,528; examples of which are given.

Abstract: 1,161,060. Coating apparatus. THOMAS GAMESON & SONS Ltd. 11 March, 1968 [10 Dec., 1966], No. 55402/66. Heading B2L. [Also in Division C7] Articles to be coated are contained in baskets 25 and are carried intermittently from a loading point to an unloading point in an arcuate path about shaft 20, and during a pause in their motion are lowered into and lifted out of the coating material in tank 41 by vertical movement of arms 22, then after dipping are centrifuged to remove surplus coating materials by rotation of the appropriate basket 25 and shaft 24 by its motor 35. While being dipped the articles may be subjected to an upward and downward agitation by tilting of the particle arm 22 by a piston and cylinder device. At the unloading point the coated articles may be released from the baskets 25 by lowering of shaft 23 and basket base 26, and may be quenched in water or other fluid. The loading and unloading points may be the same, and the coated articles may be quenched after being removed from the apparatus.

Title: Automatically regulated central heating system
IPC: F24D19/10
Filed: 1973-11-29
Abstract: 1449619 Valves PONT-A-MOUSSON SA 29 Nov 1973 [20 Dec 1972] 55452/73 Heading F2V [Also in Division F4] A central heating system includes a three-way mixing valve G upstream of a thermostaticallycontrolled valve associated with at least one of the radiators. The system also includes a restriction H, and two pressure take-off pipes 15, 16 to measure the pressure differential in the fluid passing through the restriction. The restriction may be in the form of an apertured plate 18 located, as shown, outside the valve  housing or integral with the housing (Fig. 4, not shown); or be Venturi-shaped (Figs. 5, 6, not shown); or be a butterfly valve (Figs. 13, 14, 16, not shown); or be the three-way valve itself. The pipes 15, 16 extend from the upstream and downstream sides of the restriction to the respective sides of a diaphragm 14. The diaphragm is connected via a rod 10 to conicallyshaped valve members 8, 9; a spring 12 being provided to bias the valve. In the embodiments wherein the valve G itself forms the restriction, the upstream take-off pipe 15 may be in communication with either pipe 2, 3 (Fig. 7, not shown); or be in communication with pipe 3 via the hollow shaft of rod 10 (Fig. 8, not shown). In this latter case, the end of shaft 10 may have lateral inlet openings (Fig. 9, not shown). Alternatively, the downstream take-off pipe 16 may be in communication with the upper surface of diaphragm 14 (Fig. 10, not shown) in which case the biasing spring 12 is also disposed in the upper half of chamber 13. The fluid in pipe 2 may then flow directly into the lower half of chamber 13. In the embodiments wherein the pipes 15, 16 enter the valve housing on either side of the valve in lines 2, 4, the ends of the pipes 15, 16 may have respective lateral inlet and outlet openings (Figs. 12, 13, not shown). In operation of the central heating system, for example if the temperature in a room should fall, the thermostatically-controlled valve opens, decreasing the existing pressure in line 4. The difference in pressure across the restriction H, causes the rod 10 to move downwardly, closing off the pipe 5, thus allowing more hot water to pass through the mixing valve G to the radiators. Should the temperature in a room rise, the reverse occurs, allowing cooler water from pipe 5 to flow to the radiators.

IPC: F02M59/00
Filed: 1971-12-02
Abstract: 1367337 Fuel injection pumps SOC INDUSTRIELLE GENERALE DE MECANIQUE APPLIQUEE 2 Dec 1971 [4 Dec 1970] 55896/71 Heading F1A The opening of the delivery valve 4 of a fuel injection pump is resisted by a spring 5 and by fuel in a chamber 16 having to be displaced by the valve through a passage 18, 17, 19 to a supply chamber 26, 8, the passage being so arranged that it decreases in flow area with increasing valve opening. In the closed position of the valve shown the groove 17 in the valve 4 aligns with the passage port 19. After a predetermined valve lift the groove moves out of alignment with the passage 19, whereafter further flow from the chamber 16 is restricted by having to flow through a small annular clearance (a), Fig.3 (not shown) between a reduced diameter portion (4c) of the valve and the bore 14 in which it slides. Fuel delivered past the valve enters an annular chamber 13 and flows therefrom through a passage 24 to a delivery line 6. In the event of a pressure wave occurring in the line 6 after closure of the valve 4, the pressure pulse is received in the chamber 13 and acts on a frusto-conical valve surface therein, thereby to cause re-opening of the valve.

In an electric discharge device, e.g. a fluorescent lamp having tungsten wire coil electrodes, the electrodes are coated with emissive materials comprising a mixture of barium, strontium and calcium oxides, iron boride in an amount of 0.05% to 10% by weight thereof, and at least one powdered high melting point reducing metal from the group zirconium, hafnium, niobium and tantalum in an amount of 1% to 8% by weight thereof. Preferably the iron boride, which may be of the FeB or Fe 2 B type, is present in an amount of 0.5% to 3% by weight; the reducing metal powders prevent oxidation of the iron boride during processing. A number of examples are given. The coating is stated to reduce to less than 15 dB. the radio noise of a fluorescent lamp during operation.

Abstract: 1458515 Respirators DRAGERWERK AG 6 Dec 1973 [22 Dec 1972] 56721/73 Heading A5T A respiratory apparatus includes a heat exchanger for cooling inhalation gas, comprising a duct 2 containing a material 7 of thermal conductivity less than 2.5 B.T.U./hr. F. ft. having interstices through which the inhalation and exhalation gas flow. Hot inhalation air e.g. at 100C enters a filter housing 1 of a self-rescue apparatus, passes through catalytic material 3 for removing carbon monoxide to mouthpiece 4. The air heats material 7 only slightly due to the latter's low thermal conductivity but a large quantity of heat in the inhalation air heats and evaporates saliva which was deposited on material 7 during the previous exhalation phase, thus cooling the inhalation air. Exhaled air flows through material 7 to exhalation valve 5. The material may be glass, ceramic or plastics, non-porous and in wire, chip, screen, granule, ball or tube form.
