Title: Improvements in or relating to the manufacture of sintered metallic compositions
Inventor: BROWN GEORGE ANGUS
IPC: C22C1/10
Filed: 1959-09-08
Abstract: A sintered composition consisting of a matrix metal or alloy such as Ni, Co, Fe, Cu, W, Mo, Pb or Ag which form easily reducible oxides, and a dispersed phase of one or more refractory oxides such as Al2O3, SiO2, MgO or BeO is formed by precipitating from a solution of a salt of the matrix metal a compound which on heating forms the metal oxide, and also precipitating from a solution of a salt of the metal of the refractory oxide a compound which forms the refractory oxide on heating, mixing the precipitates, heating to form the respective oxides, heating in a reducing atmosphere to form the matrix metal and refractory oxide and then compacting and sintering the mixture.  The sintered composition contains less than 1% by weight of the refractory oxide and the precipitation from aqueous solutions of the respective metal salts is effected by the addition of alkali metal hydroxides, ammonia, alkali metal carbonates, alkali metal oxalates, oxalic acid, alkali metal formates and formic acid.  The mixed precipitates are ground to minus 300 mesh B.S.S. and the decomposition and reduction of the precipitate may be effected in a single operation by heating in a reducing atmosphere.  In an example basic copper sulphate and basic aluminium sulphate are separately precipitated from aqueous solutions of copper sulphate and aluminium sulphate with aqueous ammonia.  After mixing, filtering and drying, the mixed precipitates are heated in air at 850 DEG C.-900 DEG C. to form the oxides, crushed to minus 300 mesh B.S.S., reduced in hydrogen at 300 DEG C. and then compacted at 35-50 times p.s.i. and finally intered in hydrogen or vacuum at 1040 DEG C.  Specification 893,425 is referred to.

Title: Improvements in and relating to the manufacture of master models for use in the production of industrial models, such as automobile bodies
Inventor: KISH STEVEN PETER
IPC: B28B7/34
Filed: 1950-12-18
Abstract: 741,803. Surface gauges. KISH PLASTIC PRODUCTS, Inc. Dec. 18, 1950, No. 30788/50. Class 106 (2). [Also in Groups V, XXII and XXIII] A method of making a master model of an automobile &c. having bilaterally symmetrical parts consists in preparing a preliminary model, shaping one symmetrical part to finished form and then finishing the other part by using templates made from the first part. A plaster cast 142 with built-up ribs is first taken of, say, the bonnet panel, of an automobile clay &c. master model bearing skin panel joint lines. The cast is turned over and a male plaster cast taken, the plaster being retained by walls 148. This cast 146 is trimmed to the joint lines 135 as at 150, Fig. 6, and can be used for roughing-out jigs &c. The mould 142, 148 is then used again to make a plastic cast such as a resinous plastic with a polystyrene core. The plastic model 154 is trimmed to remove irregularities reproduced from the clay model. Use is made of templates prepared from body drafts to ensure the correct panel outline. One half of the model is then shaped by cutting away and adding plastic material until a smooth surface is obtained. Scribe marks 166, Fig. 8, are made on the surface and plastic-faced templates made so that the other half can be exactly duplicated. The templates are mounted, for the latter purpose, on a framework 172, 174, Fig. 10, and surplus material is trimmed by a routing or planing cutter. If material is to be added, the surfaces are first built-up under the template and the intervening space is then-smoothed in. Finally a female reproduction is made using a strengthening frame 152, Fig. 14, and a plastic facing 184. The male and female models are used for making tools and fixtures or further models.

Title: Means for maintaining constant the radio between the displacement of a body in a predetermined direction and the number of revolutions of said body with an axis parallelto said direction
IPC: G01P7/00
Filed: 1945-11-19
Abstract: 618,953. Fluid-pressure servomotor-control systems. MEEUSSEN, L. Nov. 19, 1945, No. 30954. Convention date, Nov. 28, 1944. [Class 135] [Also in Groups XXXIV and XXXVIII] In a system for maintaining correspondence between the linear distance moved by a body and the number of revolutions of a main rotor carried by it, the main rotor is driven or braked by an electric motor and is helically threaded to an auxiliary rotor, displacement of which relative to the main rotor, due to acceleration of the body, regulates the motor or brake action so that equilibrium between the rotors is maintained. In Fig. 1, the assembly of a shifting rotor 2, helically threaded to a main rotor 1, with balls 3 to reduce friction, is mounted in a moving body with the axes of the rotors in the direction of travel of the body and relative axial movement between the rotors due to acceleration of the body is prevented by rotating the main rotor in the appropriate direction. It is demonstrated' mathematically that, under these conditions, the number of revolutions of the main rotor is a measure of the displacement of the moving body. In an electrical system for preventing axial movement between the rotors, Fig. 2, the speed and direction of rotation of a universal shuntexcited electric motor RP driving the main rotor is controlled by a tapping C, on an autotransformer ML, adjusting the armature voltage derived from an A.C. source S. Tapping C may be moved by a rod C, Fig. 2a, associated with a piston g, in a cylinder e supplied through ports k, l from a pressure conduit m, the piston being moved in.one sense or the other according to the relative openings of outlet ports a, b controlled by a member B coupled to the shifting rotor, so that speed adjustments of motor RP take place in a sense appropriate to acceleration or deceleration of the body. Methods of reducing friction between the rotors and the effect of temperature variations on the calibration are described. In an application to vehicle braking the rotors are mounted on the vehicle with their axes parallel to the running direction of the vehicle. The main rotor is driven through conical gearing from a wheel of the vehicle and movement of the shifting rotor arranged to adjust a valve to control pneumatic or hydraulic pressure in a brake cylinder.. To reduce the effect of static friction a vibratory movement may be imparted to the motor by providing it with a D.C. excitation winding V, Fig. 2, to produce a pulsating field. Applications to the measurement of deviation from course in any direction in automatic piloting systems are referred to. Specification 518,546 is referred to.
