Abstract: 635,478. Automatic aerial control systems. SPERRY GYROSCOPE CO., Inc. Jan. 5, 1945, No. 563. Convention date, Jan. 5, 1944. [Class 38 (iv)] [Also in Group XL (c)] Radar antennµ are automatically positioned in elevation and azimuth on a target by servomotors energized in accordance with reflected error signals; and the input to or output from the azimuth motor is modified in accordance with the elevation. As shown, Fig. 1, the parabolic reflector 2 of a radar-scanner, containing the transmitting and receiving antennae, is mounted to be rotated above the spin axis a-a, which is also the directivity axis of the scanner, by the motor 3. Conical scanning is effected by the fixed displacement of the reflector through a small angle about the axis b-b. In order to effect correct movement of the scanner in azimuth the input to the azimuth servomotor 11 is modified in accordance with the secant of the elevation angle through variation of the potentiometer 45, which supplies the input to motor 11, by the elevation motor 22. Alternatively, the control may be applied to the elevation motor in respect of the azimuth angle. In a further modification, not shown, a variable-speed drive is interposed between the azimuth motor and its load, which is controlled in accordance with the output from the elevation motor.

Patent GB-605983-A (GB)
Title: Manufacture of alkali chlorites
IPC: C01B11/10
Filed: 1946-01-07
Abstract: In the manufacture of an alkali chlorite, a mixture of chlorine and chlorine-dioxide, produced by the action of hydrochloric acid on an alkali and/or alkaline earth chlorate and entrained by air, is caused to undergo particle physical purification of the chlorine dioxide by being mixed with a concentrated solution of an alkali or alkaline earth chloride and/or chlorate, whereby most of the chlorine dioxide and a little chlorine are absorbed, which mixture is then desorbed, e.g. by a current of air, and further purified by being passed through a solution or milk of lime or another alkaline earth base after which the chlorine dioxide is absorbed by an alkali hydroxide and/or carbonate, the products, e.g. sodium chlorite and sodium chlorate thus obtained being separated by crystallisation and, if desired, by evaporation. The chlorates, for the production of which the unabsorbed gases from the partial physical purification may be used, fused in the production of the chlorine dioxide may be previously freed from all or a part of alkali or alkaline earth chlorides.  The solution after desorption may be used for absorbing further quantities of the gases, while the gaseous mixture from the desorption tower may be brought into contact with a solution or milk of an alkaline earth hydroxide to produce a gaseous mixture containing only air and chlorine, dioxide and a solution of alkaline earth chloride and chlorate which may be returned to the chlorine dioxide generator, as may be the alkali chlorate separated from the chlorite in the final stage while the mother liquors may be returned to the final absorption.

Title: Improvements relating to injection moulding apparatus
Inventor: NORGROVE PHILIP GERALD
IPC: B29C45/26
Filed: 1962-01-09
Abstract: 987,683. Injection moulding machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 9, 1963 [Jan. 9, 1962], No. 843/62. Heading B5A. The invention relates to an injection mould for making a washing machine gyrator having at least two helical vanes extending from a central hollow core of frusto-conical shape. The mould comprises a bolster 2 having a recess 3 therein, a plurality of mould sections 4 in the recess to define the outer surface of the core and the helical vanes, and a punch member 6 to define the inner surface of the core, the member 6 including a portion of non-circular section which facilitates removal of the gyrator axially of the mould by rotation relative to the mould sections 4. Axially extending dowel pins (not shown) on the mould sections 4 extend into slots in the wall of the recess. The mould sections may be biased upwardly by spring- loaded plungers 16 (Fig. 3) which are displaced downwardly to the operative position by lowering of the punch member 6. This is effected in the example shown in Fig. 3 by movement of a shaft 25 provided with a double start helical thread engaged by stationary pins 28 so as to effect the required rotation of the punch member to "unscrew" " the moulded gyrator from the mould sections 4. The shaft 25 and member 6 are connected through gearing 29-31. When the shaft 25 and member 6 are lowered, pins 19 engage inclined openings 17 in mould sections 15 to move them inwardly. A number of independent cooling ducts 11 (Fig. 1) provide a temperature gradient in the bolster 2 to assist flow of plastic material to the mould extremities. Specification 987,682 is referred to.

Abstract: 407,497. Laminated springs. WOODHEAD, G. A., The Grange, Old Park Road, Roundhay, and WOODHEAD & SONS, Ltd., J., Kirkstall Road, both in Leeds. Jan. 11, 1933, Nos. 909 and 22069. [Class 108 (iii).] A compound spring comprises a plurality of superposed laminated springs, each of approximate rhombus plan and having their ends in constant load-transmitting contact or connection with each other. End-contact or connection may be obtained (1) by forming each end of an upper spring A, Fig. 1, with a downwardly-projecting part a<1> supported by a horizontal extension b<1> of the spring B beneath it ; (2) by forming each end of a lower spring B with an upwardly-projecting eye b<4>, Fig. 5, or solid part b<5>, Fig. 6, supporting the end a<6> of the spring A above it ; (3) by connecting the ends by links or shackles g, Figs, 9 and 10; (4) by providing distance-pieces e, Fig. 11, loosely-mounted in slots f<1> in shackles f, the pin f of which bears constantly on the upper spring A; or (5) by connecting the ends in pin-and-slot fashion. Relative lateral movement of the superposed springs may be restrained by clips d. As shown in Fig. 1, and described in Specification 236,766, [Class 108 (iii)], the back-plate a of the upper spring A may be divided and the adjacent ends hinged to a central encastrement. The backplate a, Fig. 2, may be stiffened by one or more spring plates a<2> and the free end of the back-plate b of the spring B and, if desired, the plate a<3> of the spring A, may be bent at right-angles to form a safety stop a<4>, b2 to limit the movement of the head a<1> in case of fracture of the plate a. The plate a may be rolled to form a hollow eye. The second spring B, Fig. 10, has a double back-plate b, the members of which are clipped together, one having a rolled eye bl rigidly connected with the eye a<1> of the upper spring A by links g, while the other has an eye b<11> which receives the shackle-pin and is supported by the free end of a third spring C. In another form of the invention a spring is of orthodox form at one end and of duplex form at the other, while in a modification the spring is triple at one end and duplex at the other. Clips d formed of halves d<2> of E-section connect the springs A, B, Figs. 17, 18, plates i secured by pins k to the eye b<4> of the spring B preventing displacement of the clips along the spring. In a modification, the plates of the lower spring B are clipped together independently of the upper spring A and may be of varying lengths on both sides of the main plates of the spring B. In a further modification, the upper spring has the minimum number (two) of laminations. Friction between the ends of the springs may be minimized by the introduction of one or more rollers or of discs or plates of antifriction and noncorrosive material.
