Title: Method of producing industrial iron by means of iron sponge
IPC: B22F3/20
Filed: 1933-01-06
Abstract: Iron sponge, preferably mixed with additional substances, is pressed to form bodies which are then extruded.  The specific gravity after the initial pressing may lie between 3.5 and 8, and the body may then have ferrochromium, metal powders, phosphorus, or other materials diffused into its surface, by inserting it in an excess of the material and heating to red heat.  By suitable choice of pressures, speeds, and temperatures in the extrusion operation products containing 0.24, 0.11, or 0.045 per cent of carbon may be obtained from a preliminary block containing 1.7 per cent of carbon.  The materials mixed with the sponge may control the working properties, the strength, the resistance to corrosion, or the stability on heating.  Chromium, ferrochrome, chrome alloys, phosphorus, ferrophosphorus, copper phosphide, or copper may be used alone or in combination.  Chromium, nickel, and molybdenum jointly, or their compounds, may also be used.  To obtain a product containing 0.2-2 per cent of phosphorus, 1-10 per cent of 20 per cent ferro-phosphorus may be added, while for one containing 0.2-0.65 per cent of sulphur 0.7-2 per cent of sulphur-iron may be added.  To improve the properties of stress and hardness, molybdenum, vanadium, cobalt, or other metals, or non-metals such as carbon and silicon may be added.

Abstract: 1322541 Power steering apparatus T R W Inc 3 June 1970 [4 June 1969] 845/70 Heading B7H A fluid-operated power steering gear assembly is operated by a shaft 28 having a splined outer  end 29 to receive a steering wheel and connected to or formed integrally with an inner valve sleeve 30, connected to a torsion rod 55. The sleeve 30 is positioned within an outer sleeve 31 comprising a pair of sleeves 31a, 31b pinned together by apertured pins 32 which are open to a circumferential groove 34, Fig. 1. Slots 42 and 42a in the sleeve 31 open into pressure chamber 15 and a chamber 25 respectively, both slots communicating with axial grooves 46 of the outer sleeve 31. Inlet and outlet ports 22 and 23, Fig. 2 (not shown), are connected to the discharge and suction sides of a fluid pump (not  shown). The inner and outer sleeves 30, 31 are disposed in neutral position, Fig. 3, when the shaft 28 is in straight ahead position, such that fluid circulates through port 22, through passages 38, 36 to the groove 34, through apertures 33 to the grooves 47 in the inner sleeve 30 and to the chamber 15. A pressure chamber 14 on the opposite side of piston 13 communicates with the port 23 through piston bore 59, a transverse bore 64, a longitudinal bore 66, slots 42a axial grooves 46, circumferential groove 49 and radial passages (50), Fig. 2 (not shown). The pressure on either side of the piston 13 is equal so that the piston is static. Upon clockwise operation of shaft 28, the valve sleeve 30 is rotated relative to the outer sleeve 31, such that grooves 47 of the inner sleeve communicate with fluid under pressure which is supplied to chamber 14 causing the piston to move to the right Fig. 1, thus rotating gear sector 20 and worm 58 through balls 61, 62. The outer sleeve 31 is rotated by the worm 58 to effect follow-up movement, but the piston 13 continues to move, after movement of shaft 28 has ceased, until the inner and outer sleeves are in the neutral, Fig. 3 position, to equalize the pressure in chambers 14 and 15. Rotation of shaft 28 in the opposite direction similarly causes rotation of the gear sector 20 in the opposite direction.

Abstract: 913,700. Determining gas pressure. LABORATOIRE DES BASSES PRESSIONS. March 8, 1961 [April 8, 1960], No. 8541/61. Drawings to Specification. Class 37. The pressure within a vessel is determined by measuring the change in dielectric constant of the dielectric of a capacitor arranged to be subjected to the pressure within the vessel. The capacitor may be housed within the tank or in an external vessel, the plates being firmly secured, and the conductors being kept short to reduce parasitic capacitances. The capacitance is included in the tank circuit of an oscillator and the oscillator frequency may be compared with that of a standard oscillator to produce a beat frequency indicative of the pressure, or a single oscillator may be calibrated by first subjecting the capacitor to atmosphere, the oscillator frequency subsequently giving a direct indication of pressure. A frequency of several megacycles is suggested and some values are given. The electronic circuitry is temperature controlled.
