IPC: F15B11/00
Filed: 1961-04-21
Abstract: 988,237. Mineral-mining machines. DOWTY TECHNICAL DEVELOPMENTS Ltd. April 19, 1962 [April 21, 1961], No. 14440/61. Heading E1F. [Also in Division F1] A double-acting fluid pressure ram or the equivalent which may have pads fitted to the ends of its rods 3, 4, Fig. 1 for engaging the side walls of a tunnel to guide the cutting head of a coal-cutting machine comprises a pair of non-return valves 16, 17 connected one to each working space 5, 6 of the ram and adapted to supply fluid at high pressure to each space, and a pair of control valves 9, 11 also connected one to each working space and each capable of closing or opening to retain or vent high pressure fluid within its associated working space. Both control valves are solenoid operated and in their unenergized condition fluid is prevented from leaving the working spaces 5, 6 by the non-return valves 16, 17. If one or the other of the control valves is energized, the associated working space is connected to a reservoir line 13 or 15 so that fluid pressure from a line 18 passes through one of the non-return valves to the other space to move the piston or, alternatively, the cylinder. In another embodiment having two rams 21, 22 Fig. 2 having pistons 23, 29 with different sized rods 25, 26, 32, 34, the spaces 27, 33 associated with the larger sized rods are connected by a common pipe 36, control valve 37 and non-return valve 41 to a line 42 from a high pressure source. The line 42 is also connected by non-return valves 47, 53 and control valves 44, 49 to the spaces 28, 35 associated with the smaller-sized rods. With all control valves unenergized, the pistons are locked in position. Energization of the solenoid controlling valve 37 vents the spaces 27 and 33 so that the pistons move towards each other. Energization of the solenoid controlling valve 44 or 49 will vent the associated space 28 or 35 to cause outward movement of piston 23 or 29. When the solenoids controlling both valves 44, 49 are energized, both pistons will move outwardly. In other embodiments, the rams may have diaphragms or bellows to define the working spaces.

Title: Improvements in or relating to automatic fire arms
IPC: F41A15/14
Filed: 1946-05-16
Abstract: 612,182. Automatic firearms. LIPPERT, H. May 16, 1946, No. 14876. Convention date, April 21, 1945. [Class 92 (ii)] An automatic firearm with a one-piece breech-block has an energy accumulator which is stressed by the forwardly moving breech - block and which, as soon as the breech block has reached its. forward end position, brings a breech-block locking member into looking position. In Figs. 1 and 3, the barrel 2 and breech casing 1 are secured together and can move rearwards on slides on the cradle 3 against the action of a spring 4. The breechblock 5 is under the action of a spring 6 and carries a round bolt 9 whose ends 10 are flattened to slide in slots 11 of the casing 1. As the bolt approaches its forward position a roller 14 on the arm 13 of bolt 9 engages a member 7 slidably mounted on the cradle 3. A spring 8 is thus compressed and tends to rotate the bolt. When the bolt reaches its closed position its ends 10 clear the slot 11, and spring 8 then rotates the bolt to a locking position in which the ends 10 bear against rounded surfaces 12 at the ends of the slots. On recoil the roller will strike the edge of a recess in the member 7 and the bolt will return to the position shown. Recesses 15, 16, Fig. 8, formed in the bolt coact respectively with the firing pin 17, and a spring-controlled detent 22. As the breech-block approaches its forward position and the bolt is rotated by member 7; an edge of the groove 15 is first moved from its position, locking the the firing-pin as shown, and then an edge of groove 16 depresses the detent 22 to release the firing-pin. In a modification the bolt 9 has an additional arm which moves to locking engagement with the breech casing when the bolt is rotated. The Specification as open to inspection under Sect. 91 describes also a construction in which the member 7 is carried by the barrel, its spring 8 being compressed when the barrel recoils and being held compressed by a catch which is released by the breech-block when the latter reaches its closed position. This subject-matter does not appear in the Specification as accepted.
