Patent GB-953730-A (GB)
Title: Depth control for search torpedo
IPC: F41G7/00
Filed: 1957-03-01
Abstract: 953,730. Torpedoes. CLEVITE CORPORATION. March 1, 1957 [March 2, 1956], No. 6990/57. Drawings to Specification. Heading B7A. [Also in Division G3] A torpedo is caused to follow a target by acoustic signals transmitted from the torpedo and reflected back from the target. After launching, the torpedo initially follows a spiral scarce path, upwards and downwards between two predetermined levels, until echo signals are received from the target. The latter terminate the spiral search path and cause the torpedo to follow the target. The elevating surfaces are positioned by a servosystem which is controlled by an electrical relay circuit conditioned by the output of a bridge networkresponsive to the echo signals and sensitive to their direction. If the target range is greater than 1100 feet, the torpedo will follow the target in depth and if the target penetrates either the search floor or ceiling the torpedo will move to that level and follow it in azimuth. If a larger echo is received more than six seconds after the previous one the target is regarded as lost and the relay system automatically causes the torpedo to resume the spiral search path until the target is re-located. For target ranges under 1100 feet, the relay system is conditioned by the target echo signals so as to permit the torpedo to pass either the search floor or ceiling levels during pursuit. If a target echo signal is received more than 1 1/2 seconds after the previous one, the target is regarded as lost and the relay system automatically causes the torpedo to proceed in the direction of the last heading.

Title: An improved feeler-pin device for gauging or measuring purposes
IPC: B23Q17/22
Filed: 1955-03-15
Abstract: 764,740. Contour gauges. DECKEL, H., and DECKEL, F. W. March 15, 1955 [March 19, 1954], No. 7482/55. Class 106 (2). A feeler-pin measuring device comprises an adjustable feelerpin 70, a transmission linkage and an indicator 84, these parts being mounted in a holder 10 fitting into and rotatably driven by a spindle 12, the transmission linkage including a longitudinally - extended oscillatable plate 34, the axis of oscillation of which is parallel to the adjusting direction of the feeler 70 or its carrier 54, both the transmission linkages, which leads to the indicator 84, and the feeler 70 engaging the plate 34. In Fig. 2 the device is being used to verify the centring of bore 124 with respect to the axis of the spindle 12. The feeler 70 is set at the required angle to an arm 66 with which it forms a bell-crank lever, being pivoted at 60 on the sliding carrier 54 which is secured by a clamping screw at the required position on the part 28, depending on the diameter of the bore 124. The part 28 is fixed to a shaft 18 which rotates with the spindle 12 so that the feeler 70 moves in a circular path, its point in contact with the sides of the bore 124. The arm 66 engages at 72 a cylindrically-shaped side 36 of the plate 34 which is pivoted at 32 to the part 28. The other side 38 of the plate 34 engages a pin 74 on which rests the flange 94 of a bush 96 axially movable relatively to the shaft 18 on bearings 98. A bell-crank lever 88 links the bush 96 to the indicator 84. Any relative movement of the feeler 70 in the bore 124 moves the arm 66 to which it is secured, tilting the plate 34, moving the pin 74 which displaces the bush 96. The lever 88 moves with the bush to give an indication on the indicator 84. A spring 102, Fig. 4, urges the side 38 upwardly, thus pressing the feeler 70 against the wall of the bore. When external diameters are similarly tested the spring is removed by a knob 106 to an inoperative position. A plane surface may be tested by screwing a bush carrying another feeler member into the hole 116, Fig. 2, the feeler engaging the side 36 of the plate 34, and the feeler 70 being moved to an inoperative position. The part 78 carrying the indicator 84 is mounted on the holder 10 by means of a bearing 80 and can be held steady while the rest of the device rotates by means of a handle 82, the bell-crank 88 continuing to contact the flange 94 of the bush 96.

Patent GB-722441-A (GB)
Title: Manufacture of organopolysiloxanes
IPC: C08G77/00
Filed: 1952-03-24
Abstract: Organopolysiloxanes are prepared by reacting one or more organochlorosilanes, a compound containing one or more alcoholic or phenolic hydroxyl groups and an organic acid.  For complete reaction one hydroxyl and one carboxyl group are required for two halogen atoms of the chlorosilane.  With fewer hydroxyl groups organo-halogeno-polysiloxanes are produced and with fewer carboxylic groups polysiloxanes containing alkoxy or aryloxy groups are obtained.  The remaining halogen can be esterified with alcohols or reacted with alkylene oxides.  The polymerization reaction produces hydrogen chloride and an ester as by-products. The evolution of hydrogen chloride can be used to control the temperature of reaction. The reaction may be effected by adding the acid and hydroxyl compound to the silane(s) or by adding the hydroxyl compound to a mixture of silane(s) and acid or vice versa.  In examples: (1) 1.6 mol. of methanol are introduced over a period of thirty minutes into a mixture of 1.5 mol. dimethyldichlorosilane and 1.6 mol. glacial acetic acid, hydrogen chloride removed by heating for an hour under reflux and the ester distilled off.  The residue is a viscous dimethyl silicone oil containing 7 per cent volatiles compared with 45-50 per cent volatiles for an oil from the hydrolysis of dimethyldichlorosilane with water; (2) 3.83 mol. of butyl alcohol are gradually added to a mixture of 0.83 mol. monomethyltrichlorosilane, 1.32 mol. of dimethyldichlorosilane and 2.64 mol. glacial acetic acid.  Hydrogen chloride is removed by heating under reflux and butyl acetate removed by distillation leaving a silicone resin as residue.
