Title: Improvements in or relating to control carriages associated with movable weirs
IPC: E02B7/44
Filed: 1955-01-17
Abstract: 764,042. Control of two motors. AUBERT, J. Jan. 17, 1955 [Jan. 21, 1954], No. 1408/55. Class 38(3) [Also in Group XXI] Comprises a control arrangement for raising a weir flashboard 1 from its fully open position IV to any one of the more or less closed positions I to III. The arrangement includes two electric motors one of which, 11, rotates an arm 4, through gearing 6, 7, 5, about a pivot 10. The other motor 16 drives a winch 15 on which a cable 14 is wound, the other end of the cable being connected to a hook 13 on an arm 12 pivoted at 8 to the arm 4. The hook is engageable with a bar 9 on the flashboard. The invention resides in means for automatically switching in the motor 11 at the instant that the hook 13 engages the bar 9. This is effected by the operator closing change-over switch 41 to energize motor 11 in the direction to swing the arm 4 sufficiently to bring hook 13 into proximity with the bar. He then opens switch 41 and closes change-over switch 46 to energize motor 16 in the direction to start winding in the cable. When 13 engages 9 and starts to raise the flashboard there is a surge of current through the transformer 23 which operates relay P to close contact P<SP>1</SP> momentarily. This energizes relay R and a maintaining circuit for R is set up by R<SP>1</SP> (now closed by R) and T<SP>1</SP> (previously closed by relay T which became energized when 46 was closed). R instantly closes R<SP>2</SP> and R<SP>5</SP> (opening R<SP>3</SP>, R<SP>4</SP>) to switch in the motor 11 for the lifting. Relay T acts with a five seconds delay in the circuitbreaking direction.

Title: Improvements in or relating to guidance systems for missiles
Inventor: KELLIHER MAURICE GORDON
IPC: F41G7/22
Filed: 1960-01-15
Abstract: 920,713. Automatic steering control. VICKERS RESEARCH Ltd. April 6, 1961 [Jan. 15, 1960], No. 1555/60. Drawings to Specification. Class 38 (4). [Also in Group XL (c)] In a system for automatically guiding a missile towards a target, the axis of a movable head on the missile, responsive to energy radiation from the target, is automatically maintained pointing towards the target by an electrical servo-system, and a gyro, responsive to rate of turn of the head in space, controls the steering of the missile to reduce the rate of turn of the head. As described, a pair of ultrasonic detectors responsive to propeller noise of a target ship are mounted at a fixed angle to each other within the plastic nose of a torpedo. Electric signals from the detectors are amplified and compared with each other, any difference serving to operate a motor which rotates both detectors to maintain their resultant axis directed towards the target. Signals from a rate gyro movable with the detectors are effective when excessive to adjust a control surface on the torpedo a fixed amount in the appropriate sense to reduce the rate of turn of the line of sight in space. When the torpedo is first launched the automatic steering is inoperative and the detectors are scanned until the target is found and sufficiently near to cause the sum of the signals from the detectors to operate a relay engaging the automatic steering system. If the target is lost, scanning is resumed. Heat or radio energy may be utilized and radiant energy may be transmitted to and reflected from the target.

Abstract: 911,854. Mixing-appliances. DRAISWERKE G.m.b.H. Jan. 13, 1961 [Dec. 8, 1960], No. 1561/61. Class 86. A mixer for pulverulent and granular materials especially thermoplastics comprises a horizontal cylindrical container 1 having an axial shaft 8 and stirrers 12, 13, a feed hopper 3 and in the ends of the drum circular intake and outlet orifices 4, 6 which are coaxial with the shaft 8. Material is fed, and the shaft rotates, at such rates that the materials are centrifuged to form on the inner surface of the drum an annular layer 14 the inner diameter of which is greater than that of the intake orifice 4. The shaft 8 also carries discs 15 the rims of which enter the annular layer so that all materials must pass through the gaps between the discs and the drum. In the section A of the drum the stirrers 12 are shaped to promote, in conjunction with the rates of rotation and of material feed, sufficient friction in the mixing process to generate heat enough to granulate or gelatinize the thermoplastic ; plasticizer may be added through the radially directed nozzles 20, 21 in the drum casing or 25 carried on the shaft 8 and fed by an axial bore 23 therein. The section B of the drum is a cooling zone in which the stirrers 13 are relatively fewer and are shaped to operate with minimum friction; a cooling medium may be circulated through the jacket 16. The shaft 8 may be divided at the junction of sections A and B, that in section B being driven at the slower speed. The end wall 5 may be replaceable to permit others with orifices 6 of different diameters to be inserted, or the aperture 6 may be adjustable by pivotable segments, see Fig. 4 (not shown), which may be arranged in the manner of an iris diaphragm, or by radially adjustable segments or by a twistable tube. The stirrers may be angled to progress or extend the materials in their passage through the drum, and may sweep only 40% to 70% of the length of the drum. The ends of the shaft 8 may have counterfeed screw portions 29.

Title: Preparation of unsaturated di-carboxylic acids from cyclic poly-unsaturated hydrocarbons
IPC: C07D323/02
Filed: 1962-01-17
Abstract: Unsaturated dicarboxylic acids, including the new compounds 2-vinyl-1, 4-butane dicarboxylic acid and 4-octene-1, 8-dioic acid, are prepared by organizing an unsaturated hydrocarbon to produce an intermediate azonolysis product, introducing into a solution of the latter excess molecular oxygen at a pH of 10 to 12 in the presence of a heavy metal oxide, acidifying the oxidation product and recovering the acid. "Heavy metal oxide" is defined as an oxide of a metal of Group Ib, IIb, VIIa and VII, e.g. oxides of silver, copper (cupric), cobalt, manganese, iron (ferric), lead, mercury and nickel.  The amount of metal oxide catalyst: azonolysis product may vary between 0.1 to 1:1. A base is used to control the pH.  The decomposition occurs in a solvent, e.g. water or alcohol, at 30-50 DEG C. The examples describe the preparation of (1) 4,8-dodecadiene-1, 12-dioic acid from 1,5,9-cyclododecatriene; (2) 2-vinyl-1, 4-butane dicarboxylic acid (b -vinyl adipic acid) from 4-vinyl-cyclohexene; (3) 4-octene-1, 8-dioic acid from 1,5-cyclooctadiene; the catalyst being silver oxide in each case. 1,2,4-butane tricarboxylic acid is prepared by ozonolysis of vinyl adipic acid followed by oxidation with hydrogen peroxide in formic acid. Succinic acid is similarly prepared from 4-octene-1, 8-dioic acid. The dimethyl ester of vinyl adipic acid is prepared from the acid and diazomethane.ALSO:Addition and condensation polymers are prepared from 2-vinyl-1, 4-butane dicarboxylic acid (vinyl adipic acid) and 4-octene-1, 8-dioic acid. They may be copolymerized with an olefin, e.g. styrene, and the copolymer cross-linked by reaction with glycols. They may also be condensed with polyfunctional alcohols to form unsaturated polyesters which may be further reacted by copolymerization with styrene or other vinyl compounds.
