Filed: 1973-10-02
Abstract: 1431080 Hydraulic boosters MIDLANDROSS CORP 2 Oct 1973 [2 Oct 1972] 45931/73 Heading F2F In an hydraulic booster having a power chamber 110 connectible to a pressure source by a valve 60, 62 wherein the pressure operates a piston 90, a second piston 92, movable in a bore smaller than that for the piston 90, forms between it and the other piston a control cavity 190 which is connectible to the power chamber via a valve 220, 222 which is closed when the pressures in the cavity and in the chamber are substantially equal so that movement of the piston 90 under pressure in the chamber produces a greater movement of the piston 92. Actuation of a pedal 18 causes a sleeve 40 to move rightwardly thus causing similar movement of sleeves 56, 66 by a spring 74, until a sealing ring 70 abuts a seat 72 in the piston 90 blocking communication between the chamber 110 and an outlet chamber 106 leading to the pressure source 12, e.g. a steering gear pump or an accumulator; subsequent movement of the sleeve 40 disengages abutting surfaces 60, 62 on the sleeves 40, 56 respectively to allow fluid from the source to pass to the chamber 110 to actuate the pistons 90, 92, the latter operating a rod 22 to a master cylinder 23, the pedal position determining the brake force. However, when the position is reached which is equivalent to the maximum force supplied by the pressure source 12, further piston movement is caused purely by an increase in pedal actuating force; in this situation, pressure in the chamber 110 remains constant but piston movement increases pressure in the cavity 190 causing a sleeve 194 to move rightwardly. A fluted stem of an associated valve element 218 abuts a wall of the housing for the booster thus parting the valve surfaces 220, 222 to allow pressure equalization between the chamber and the cavity, and the pistons 90, 92 to move together to actuate the master cylinder 23. Upon pedal return, the pressure in the chamber 110 exceeds that in the cavity 190 so that the element moves leftwardly to allow flow therebetween for pressure equalization. Upon pressure failure in the booster, a cup-shaped member 54 coupled to the sleeve 40 engages the piston 90 for direct mechanical actuation, the pistons 90, 92 moving together with the valve 220, 222 operating as above for forces above the pressure source maximum.

Abstract: 1447025 Propellants USA NAVY SECRETARY OF 14 Oct 1966 46154/66 Heading C1D A propellent composition is prepared by dissolving nitrocellulose in a casting solvent containing an explosive plasticizer, adding a lead oxide or a lead salt and a compound, e.g. tolylene diisocyanate, to cross-link the nitrocellulose, and curing to form a gel. The propellant may be cast directly in, and bonded to, a rocket motor. Nitroglycerine or diglycol dinitrate may be the explosive plasticizer. Red lead, lead stearate, dibasic lead phthalate, or tribasic lead maleate may be added to act as a ballistic modifier and cross-linking catalyst. Other ingredients are ethyl centralite, nitrodiphenylamine, carbon black, and triacetin. In order to prevent gassing during curing, the nitrocellulose is pre-treated with a solution of phenyl isocyanate in carbon tetrachloride, or phenyl isocyanate is stirred with the propellent mixture and then removed under reduced pressure before the curing step. Methods of preparation described include (a) slurrying the nitrocellulose with 95% ethanol, methylene chloride, diethyl ether, or chloroform, and removing these compounds before adding the polyisocyanate; (b) dissolving the nitrocellulose in dimethyl sulphoxide, and pouring the solution through a perforated plate into water to form porous pellets; (c) stirring the nitrocellulose with triacetin at - 40‹ C. before adding the other casting solvent ingredients at a higher temperature. Other suitable polyisocyanate cross-linking agents are given, and reference is also made to the use of titanates, epoxides, and anhydrides for this purpose.

Abstract: 1,051,397. Jointing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 16, 1965 [Nov. 19, 1964], No. 48621/65. Heading B3V. [Also in Division H1] Two parts are joined by the action of a beam of radiation all or most of the energy of which is chosen to be in a frequency range such that the radiation will be selectively absorbed by one of the parts. The beam is directed through that part which does not absorb the radiation and is absorbed by the second part substantially at the interface between the two parts to weld them together. The process may be carried out in air, in vacuo, in a protective atmosphere, in an etching gas or liquid, in an atmosphere repressing evaporation of volatile components, or, to bond materials such as cubic tin which are unstable to heat, in a liquid coolant. Uses suggested are the formation of hetero junctions between different semi-conductors, of metal to semi-conductor bonds, and of bonds between two pieces of the same basic semi-conductor having widely different dopant concentrations. In an example a germanium body (#E = 0À9eV) is joined to a cadmium sulphide body (#E = 2À4eV) using a ruby laser (6900 - 1À8 eV). Bonds may be made at spaced locations on the bodies and several wafers split from the composite body e.g. by sawing between the bonds. During bonding, carried out in air or in vacuo, the bodies may be held together under pressure and/or preheated to vary the conditions of bonding. Radiation of wavelengths 9000 - 18,600  may be used to bond germanium to gallium arsenide (#E = 1À4 eV).
