IPC: B60T13/16
Filed: 1949-06-17
Abstract: 683,807. Hydraulic brakes. CLAYTON DEWANDRE CO., Ltd. June 14, 1950 [June 17, 1949], No. 16214/49. Class 103 (i). In a hydraulic brake system for vehicles of the type in which the pressure for applying the brakes is produced by throttling the delivery from a pump 11, the control valve 1 is such that it provides hydraulically separate braking systems for the front and rear wheels, both systems being operable by power from the pump 11, and the system to the rear wheels being operable manually in the event of the failure of the power supply. Operation of the brake control pedal advances a plunger 20 in the cylinder 18 of the valve 1 so as to close the outlet from the cylindrical extension 17 of a piston 21, connected by passage 38 and pipe 8 to the pump 11. The increased pressure behind piston 21 acts directly by a pipe 13 connected to a T-piece 12 in the pump delivery conduit upon the front wheel brakes and indirectly on the rear wheel brakes by acting on a piston 21 having an extension 25 forming a valve closing the central port in a master cylinder plunger 28 and thereafter forcing the plunger to apply the rear wheel brakes. A packing ring 34 on the piston 21 ensures that the two systems are hydraulically separate and in event of failure of the power supply, continued movement of plunger 20 carries with it the piston 21 and plunger 28 to apply the rear wheel brakes by manual effort.

[Class 51 (ii)] [Also in Group XXIII] The high furnace temperature necessary for the melting of ceramic refractory materials having a fusion temperature above 1371‹ C., is attained by burning a fluid fuel in suspension in the furnace in the presence of an oxygen-containing gas continuously supplied to the furnaces, at a temperature above 815‹C. The fused refractory may be used for the manufacture of mineral wool, by shredding in an air blast, or for cast fused refractories or grog. The material used may be fireclays, kaolins, bauxite, kyanite, sillimanite. or topaz and may be preheated to a temperature (e.g. 1538‹ C. in the case of kaolin) below its melting point by passing through a rotary kiln on its way to the furnace, the kiln being heated by the exhaust of the furnace supplemented if necessary by auxiliary heat. The wool which may be used for high-temperature heat insulation has a maximum use temperature above 1093‹ C. With the air preheated to say 983‹ C. the furnace temperature approximates to 1982‹C.; a graph gives the observed and theoretical relationship between the temperatures.

Abstract: 919,021. Magnetic structures; magnetic storage devices. GENERAL ELECTRIC CO. Ltd. May 28, 1959 [May 28, 1958], No. 17013/58. Class 38 (2). [Also in Group II] To obtain a predetermined degree of anisotropy in a thin nickel-iron alloy film 1 (Fig. 1) formed on a glass substrate by evaporation or electro-deposition a magnetic field having a component rotating in the plane of the film is applied to it. A pick-up loop 9a, 9b and drive loops 10a, 10b and 11a, 11b are provided. The film may be produced by positioning a glass base in a chamber evacuated by an oil diffusion pump and containing a coiled tungsten heating filament which rapidly evaporates a length of nickel-iron alloy wire so that a nickel-iron alloy film of 1000  thickness is deposited on the glass base at a temperature of 350 C. Four coils arranged on opposite sides of the glass base in coaxial pairs on axes at right-angles are supplied with 50-cycle alternating currents in phase quadrature to produce a rotating field of approximately 100 oersteds in the plane of the film. To provide a small degree of anisotropy an extra magnetic field is applied in the preferred direction. This may be done by arranging the axis of one pair of coils in that direction and by securing that the amplitude of the field they produce is greater than that produced by the other pair of coils. The fields may be applied during formation of the film or subsequently. The evaporation chamber is cleaned by ionic bombardment. The film is photoetched to form a disc as in Specification 919,022 or to form the units of the data store described in Specification 919,023. According to the Provisional Specification one or more elongated electrodes of gold is first evaporated on to the glass base, a circular film or films of nickel-iron alloy is then deposited thereon through a mask. This is followed by deposition of an insulating layer of silicon monoxide or magnesium fluoride and then one or more gold electrodes over and at right-angles to the first gold electrodes are deposited on the silicon monoxide. Leads are attached to the electrodes by silver paste and the rotating magnetic field may be applied to the magnetic films after formation by passing alternating currents in quadrature through the electrodes at right-angles to each other.
