Title: Improvements in or relating to submarine mines
IPC: F42B22/18
Filed: 1922-11-28
Abstract: 213,313. Vickers, Ltd., and Elia, G. E. Nov. 28, 1922. Mines, marine.-An automatically-anchored submarine mine is provided with an hydrostat, which, during the descent of the sinker to the sea bed, maintains the mine at a predetermined depth below the surface. Means may be provided to delay the separation of the mine from the sinker until it has sunk to a depth lower than the aforesaid depth but shallower than the depth at which the mine would be damaged by hydrostatic pressure. As shown, the mine A, Fig. 2. which is of the kind described in Specification 212,971, and the sinker B are held together bv an hydrostatic device P, the diaphragm p of which is moved down at a certain depth when the hydrostatic pressure thereon overcomes a spring p<3>. The stem p<2> of the diaphragm then releases balls S, disengaging a link R and thereby allowing the sinker with the hydrostat to drop away from the mine. The mooring cable F is paid out from a drum C in the sinker at a speed controlled by a brake-gear pump K according to the setting of a screw k<3>, Fig. 3, in the passage k<2> from the outlet to the inlet of the pump. If the mine rises to a predetermined depth, an hydrostat G carried by the mine closes a switch f<1>, g<2> energizing a solenoid E in the sinker. The armature core e of the solenoid is drawn down against a spring n<4> and shuts a valve m<1> in the passage k<2>, thereby stopping the drum C. If the sinker has not reached sea bottom by then, it drags the mine down in continuing its fall; the hydrostat G thereupon again opens the switch f<1>, g<2> which causes the valve m<1> again to open allowing the drum C again to pay out the mooring cable. The hydrostat G thus maintains the mine substantially at a given depth whiles the sinker is falling. When the sinker touches bottom, and the mine is at the predetermined depth, the drum C remains locked by the action of the valve m<1>. A pawl operated by contact with the sea bottom may be provided to lock the drum C in a permanent way.

Title: Pull gun
IPC: B21J15/06
Filed: 1956-10-29
Abstract: 830,447. Blind riveting. HUCK MANUFACTURING CO. Oct. 29, 1956 [Feb. 3, 1956], No. 32893/56. Class 83 (4). [Also in Group XXV] A fluid-actuated pull gun comprises a body defining a bore for a piston 46, a piston-rod 44, a second piston 64 in a second bore 62, the first bore being adapted to have fluid circuits successively established at opposite ends of the first piston to drive the first piston in opposite directions, the second piston being actuated in response to a predetermined fluid pressure in the first bore by means responsive to the fluid pressure in the first bore for establishing fluid circuits acting on the second piston, a first valve means 20 for establishing the fluid circuits to the first bore, the means responsive to the fluid pressure in the first bore establishing a fluid circuit between the second bore for the seccnd piston and a fluid reservoir 70, and a third bore defined by a housing 7, a third piston 24 being mounted in the third bore, the first valve means being selectively operable to actuate the third piston to force fluid into the first bore. The slide valve 20, actuated manually by a trigger 14 admits compressed air through a port 30 to drive pistons 24 and 28 to the left, Fig. 1, thus displacing fluid, e.g. oil, from a cylinder 11 into a cylinder 48 to drive the piston 46 upwards. Piston 46 carries the hollow piston-rod 44 which has its longitudinal axis offset so that the distance between the axis and the end 49 of the gun is a minimum. A collet 40 carried on the piston-rod is adapted to grip the shank 84 of a rivet pin 81 and pull it through the rivet sleeve 85 deforming the latter against the reaction of an outer anvil 56 which is mounted on a tubular member 58 bearing against the piston 64 in the secondary cylinder 62. At a pressure in main cylinder 48 predetermined by the adjustment of a spring valve 68 trapped fluid is displaced from the cylinder 62 into the reservoir 70, Fig. 3, permitting the anvil 56 to retract, Fig. 8, transferring the pull-reaction to a fixed inner anvil 54 so that on continued movement of piston 46 frangible locking portions 87 of the rivet are deformed as shown in Fig. 5B. Further movement of piston 46 breaks the rivet shank at 95, the free portion being ejected. Release of the trigger 14 admits air to return pistons 24 and 46 and also recharges the cylinder 62 with fluid, thus advancing the anvil 56 again. Specification 629,098 is referred to.

Abstract: 748,436. Expansion joints. DURATUBE & WIRE, Ltd., and THOMPSON, R. W. S. Feb. 3, 1955 [Nov. 26, 1953], No. 32911/53. Class 20(4). A joint strip, particularly for expansion joints between slabs c, d forming e.g. a wall, or a road, or an airfield run-way surface, comprises a strip e, formed of an elastic thermo plastic, e.g. rubber or plasticised polyvinyl chloride, and having on one, or as shown, on both sides, a plurality of parallel longitudinal ribs whose outer edges lie in a straight line, as shown, or on a slightly curved line, convergent with the central transverse axis of the strip. The ribs, which may be upright, or slightly curved, with respect to the plane of the strip, are preferably in staggered relation as to opposite sides of the strip so that when the strip is thrust into a tapering space f, the ribs, and the strip itself, become elastically deformed to increase the grip on the sides of the space f. The space f may be formed by cutting one, or both edges, of the slabs, or in the case of concrete, during the moulding process. A groove may be cut when it is desired to provide a fluid resisting joint along the. line of an existing crack in a concrete construction.

Abstract: 896,734. Semi-conductor devices. FAIRWEATHER, H. G. C. (Barnes Engineering Co.). Sept. 28, 1960, No. 33303/60. Class 37. [Also in Group XL (b)] A selective thermistor bolometer comprises thermistor flake and a layer having selective infra-red absorption in heat-conducting contact with the flake. In the arrangement shown in Fig. 1, radiation enters through window 2, passes through an absorbing layer of talc or talc suspension in a plastic and is reflected back through this absorbing layer by a mirror layer 6 of gold film. The thermistor flake 7 is mounted on a metallic heat sink 9 and is insulated both from it and the gold film by insulating layers 8. Such a bolometer has two strong absorption bands at 9.6 and 15Á. In the arrangements shown in Fig. 2, radiation passes through a mica window which excludes radiation above 15 and is reflected by a magnesium oxide block 3, the reflected radiation containing nothing below 13Á. The reflected radiation is received on a bolometer of the type described above. In both cases additional bolometers not arranged to receive radiation may be provided for ambient temperature compensation. The Specification refers to the use of transparent thermistors of germanium and silicon and to heat sinks of magnesium oxide beryllium oxide quartz and sapphire. The composition of a plastic being manufactured may be monitored by making the absorbing layer of the thermistor of the same material. Radiation is passed through the plastic to the thermistor which provides a minimum output until the composition of the plastic varies.
