Title: Pressure controlling device for use in raising sunken ships by compressed air
IPC: B63C7/12
Filed: 1940-06-20
Abstract: 538,326. Raising sunken ships; fluid-pressure servomotor systems. ZULVER, C. June 20, 1940, No. 10622. [Class 68 (ii)] [Also in Group XXIX] In raising sunken ships by replacing water by compressed air a desired ratio between internal and external pressure is maintained by operation of main valves controlling air pressure inside the ship through a fluid-pressure servomotor system comprising pilot valves operated by a piston subjected to the difference between internal and external pressures. The piston, which may comprise parts 5, 6 of different diameters to enable the internal pressure to be maintained somewhat higher than the external pressure, is subjected on its upper side to the air pressure within the ship through a pipe 3, and on its underside to pneumatic pressure equal to the hydrostatic pressure, a valve 15 controlling a supply of compressed air from a pipe 20 in accordance with the hydrostatic pressure applied to a diaphragm 13 being provided for the purpose. Upward movement of the piston under excess external pressure operates a pilot valve 33 to cause opening of a main valve 54 admitting compressed air from a supply 52 to the ship at 1. Downward movement of the piston on decrease of external pressure operates the pilot valve to cause closing of the main valve and at the same time operates a second pilot valve controlling a second main valve which permits escape of air from the ship. A third pilot valve also operated by the piston 5 may be provided to control the speed of the compressers supplying air to the ship.

Abstract: 1,191,098. Making electrical connections; shearing. AMP CORP. 28 Feb., 1969 [7 March, 1968], No. 10882/69. Headings B3A, B3Q and B3W. Apparatus for trimming and electrically connecting the ends of wires comprises, a connector crimping die 82, 84 and a crimping anvil 62, 64, means for moving the die and the anvil relatively towards and away from one another, means 90, 90<SP>1</SP> to co-operate with the die for trimming the wire ends during initial relative movement of the die and anvil towards one another, and a wire positioning device, 126, 126<SP>1</SP> disposed on each side of the anvil, each device 126, 126<SP>1</SP> being adapted to hold one of the wires, move the wire end when trimmed towards the anvil and position the trimmed wire end in a substantially U-section uncrimped electrical connector 14 supported on the anvil. Wires 6, 8 of a twisted pair 2 are laced through the device 126, then led through notches 96, 98 in the shear member 90, through the cavities of dies 82, 84 and through a gap 45a between bosses 45 of a frame 44. The wires 10, 12 of a second pair 4 are similarly led from the device 126<SP>1</SP> to the gap 45a. A handle (52) is rotated through a complete revolution to cause plates 32, 34 to move downwardly and then upwardly, Fig. 2 (not shown). During the initial part of their downward movement, die blocks 58, 60 are swung about pins 66, 68 by the action of cam rollers 70, 70<SP>1</SP> on cam surfaces 74, 74<SP>1</SP>. The members 90, 90<SP>1</SP> are moved relatively downwardly along surfaces 67, 69 by bell-cranks 108 as the die blocks swing towards each other, thereby trimming the ends of the wires and leaving them projecting obliquely into the cavities of the dies 82, 84, Fig. 5. Further movement of the plates 33, 34 causes relative upward movement of an arm 78, which engages fingers 140 thereby rotating the positioning devices 126, 126<SP>1</SP> and the wire ends upwardly to place them in connectors 14, which are held by clips 63. At the end of the downward stroke of the plates 33, 34, the dies 82, 84 bend over the upstanding side walls of the connectors thereby securing the wires in pairs of aligned slots 22 in the connectors, the edges of the slots penetrating the wire insulation to establish electrical contact, Fig. 17 (not shown).
