Title: Polyester coating compositions and electrical conductors coated therewith
IPC: H01B3/30
Filed: 1957-05-13
Abstract: An insulating enamel for electrical conductors is the reaction product of 1 equivalent of a polyester as claimed in the parent Specification and more than 2, but preferably less than 8, equivalents of a polyisocyanate.  The polyester is the reaction product of (a) 25-56 equivalents per cent of a lower dialkyl ester of terephthalic and/or isophthalic acid; (b) 15-46 equivalents per cent of ethylene glycol; and (c) 13-44 equivalents per cent of an aliphatic saturated polyhydric alcohol having at least three hydroxyl groups.  The polyisocyanate is preferably the reaction product of a diisocyanate and a di- or poly-hydric alcohol and may be blocked with a phenol.  The electrical conductors are insulated by coating the wire with a mixture of the polyester, the polyisocyanate and a solvent, e.g. cresol, xylenol, xylene, petroleum hydrocarbons or ethyl acetate and thereafter baking the wire to cure the coating.  In examples the wire-coating composition comprises a polyester of dimethyl terephthalate, ethylene glycol and glycerine, a polyisocyanate obtained by reacting 3 mols. of tolylene diisocyanate and 1 mol. of hexanetriol and a solvent mixture of cresylic acid and aromatic hydrocarbons.

Title: Thermodynamic reaction propulsion means
IPC: F02K9/44
Filed: 1968-03-29
Abstract: 1,224,633. Rocket propulsion. LICENTIA PATENT-VERWALTUNGS G.m.b.H. March 29, 1968 [April 1, 1967; July 11, 1967], No. 15136/68. Heading F1J. The invention relates to a jet propulsion apparatus such as a rocket or ram jet unit in which an alkali metal such as potassium or lithium serves as fuel, the fuel being stored in solid form and being liquefied before entering a combustion chamber for combustion therein. The liquefied fuel discharges from the storage vessel through a Laval nozzle under its own vapour pressure, and an oxidizing agent such as a halogen e.g. fluorine or chlorine, is supplied under pressure into the combustion chamber and causes combustion of the fuel. In Fig. 1 alkali metal such as potassium is stored in the vessel 1 which is formed with a Laval nozzle 2 which projects into the combustion chamber 3, the combustion chamber having an outlet in the form of a Laval propulsion nozzle 4. Oxidizing agent such as fluorine is stored under pressure in the vessel 8 which is connected by ducts 10 having metering valves 11 to the combustion chamber 3. At starting, the fuel is heated by means (not shown) and the vapour pressure created forces the liquefied fuel through the nozzle 2, which is initially closed by a diaphragm 5, into the combustion chamber. At the same time the valves 11 are opened whereby oxidizer such as fluorine is forced into the chamber 3. Reaction of the liquid potassium and fluorine occurs and the combustion or reaction products discharge through the nozzle 4. In Fig. 2 in place of an oxidizer such as a halogen, air under pressure passed through ram intake 14 is used to produce combustion of the liquefied alkali metal in the chamber 3. When the vehicle reaches a predetermined height, a halogen may be utilized as oxidizer as in the first embodiment. In Fig. 4 a series of frusto-conical rings 18 are disposed within the fuel container 1 which is filled from below so that spaces are formed adjacent the rings 18. At starting, an oxidizer such as a halogen is passed from the container 8 into the fuel container. The resulting reaction produces heat which causes the solidified fuel to liquify. The liquefied fuel is then passed through a heat exchanger 17 on the wall of the combustion chamber 3 where it is pre-heated before passing to the nozzle 2 into the combustion chamber. Oxidizer such as halogen is passed to the chamber 3 through nozzle 13.

Abstract: 947,886. Treating yarns with liquid. DYE TUBE DEVELOPMENTS Ltd. July 27, 1962 [April 28, 1961], No. 15382/61. Headings D1F and D1L. In a method of yarn processing such as dyeing, washing or bleaching, newly-spun yarn is wound on to a perforated tube in a ring frame and the tube is subsequently placed in a perforated spindle in a processing machine, there being no intermediate rewinding. After the yarn is processed the spindle may be removed from the processing machine and the yarn wound directly therefrom. The tubes with the yarn packages therein may be stored before being placed in the processing machine. The tube may be expendable in which case it is made e.g. of paper or it may be permanent in which case it may be made of stainless steel, nylon or polythene. If the tube is of paper it may be placed over a more rigid, perforated tube before being placed on the processing spindle. In the form shown the perforated spindle 4 is detachably mounted in the flow 6 of a pressure dyeing machine. The mounting may be by screw arrangement as shown or other means such as a bayonet type joint may be used. The top of spindle 4 is closed so that the dyeing liquid entering through the hollow boss 5 is forced through the yarn 3. The tube 1 may closely fit on spindle 4, as shown, in which case the perforations in spindle and tube must be aligned or alternatively tube 1 may contact spindle 4 only at raised end portions in which case there is a space between the spindle and tube and the perforations need not be aligned.

Title: Improved process for the production of arylborazoles
IPC: C07F5/02
Filed: 1960-05-02
Abstract: Arylborazoles are made by reacting, in an inert solvent, a B-haloborazole of one of the general formulae (HNBX)3, (RNBX)3 and (R1NBX)3 with a Grignard reagent, adding to the reaction mass from about 0.01 mole to about 1 mole per mole of Grignard reagent of a tertiary aliphatic amine having alkyl groups containing from 2 to 20 carbon atoms, N,N-dimethyl aniline, pyridine or quinoline and then separating the resultant arylborazole; where R is an alkyl radical, R1 is an aryl radical and X is a halogen atom, provided that when the B-haloborazole is of the formula (HNBX)3 or (RNBX)3 then the Grignard must contain an aryl radical.  The tertiary amine breaks the borazole-magnesium halide complex and the borazole is separated from the reaction mass by distillation, extraction, recrystallisation or sublimation.  Examples describe the preparation of B-triphenylborazole from phenyl magnesium bromide and B-trichloroborazole with the addition of triethylamine, N,N-dimethyl aniline, pyridine and quinoline.

Title: Improvements in or relating to gas-heated appliances

Filed: 1932-06-04
Abstract: 384,200. Safety cut-off gas valves. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. June 4, 1932, No. 15732. Convention date, July 18, 1931. [Class 135.] Safety devices arranged in the path of, and operated by, the gases driven back by a downdraught in the flue of a gas-heated appliance, cause closure of the gas supply valve, thus extinguishing the burner and preventing the passage of poisonous waste gases back into the apartment. The safety device may depend on thermostatic or catalytic action, or may operate under pressure or by fusion. Fig. 3 shows a water-heater having a flue 15 through which a downdraught forces back the waste gases, the heat of which then causes a thermostat 20 in the flue to release a spring-actuated valve 22 which cuts off the gas supply to the burner. In the water heater shown in Fig. 4, gas passes to the main burner through a diaphragm valve 23 the diaphragm 24 of which has a small aperture 25 through which gas passes to a " guardian " flame burner 29, the top 30 of which is formed by a thermostat disc. Backdraught extinguishes the flame of the burner 29 by smothering it with the waste gases, this causing the disc 30 to flatten and close a valve 32. Pressure now builds up beneath the diaphragm 24 and causes it to close the valve 23, thus extinguishing the main burner. The "guardian" flame may also serve as a pilot light. A balanced valve 37 may close the air supply aperture 35 in the bottom of the casing under the action of the back-draught. A safety device comprising a movable impact surface in the path of the returned gases, such for example as the valve 37, connected to the gas valve, is also referred to.
