Title: Improvements in hydraulic control mechanism
Inventor: MERRITT HENRY EDWARD
IPC: F15B13/06
Filed: 1947-11-21
Abstract: 639,280. Valves ; hydraulic control mechanism. MORRIS MOTORS, Ltd. Nov. 21, 1947, No. 30904. [Classes 69 (ii) and 135] Mechanism controlling the flow of pressure liquid to and from hydraulically-operated apparatus comprises a manually - operable, balanced' piston valve which, when the liquid pressure exceeds a predetermined value, is moved automatically by pressure-responsive means from an operative 'position to a neutral position in which the apparatus is isolated both from the source and from exhaust, whilst at the same time the liquid from the source is permitted to be discharged direct to exhaust. As applied to the operation of agricultural implements drawn or carried by a tractor, a valve casing 5, Fig. 1, having an inlet 6 connected to a tractor driven gear pump and an exhaust 18 connected to a sump, houses balanced piston valves 1, 2, controlling ports 8, 9 leading to independent hydraulic motors operating the implements, and a pressureresponsive device comprising a high-pressure relief valve 20, a low-pressure relief valve 19 and loosely mounted pistons 22 associated with each piston valve. With the valves 1, 2 in the neutral position shown, pressure liquid from the inlet 6 passes via passages 13, 15, 17, ports 14, 16, and the low-pressure valve 19 to exhaust 18. On either or both of the valves 1, 2 being moved downwards manually, the ports 8 and/or 9 will be opened, followed later, due to the negative lap of the piston lands, by the interruption of communication between the passages 13 and 17 and hence between inlet and exhaust. Pressure then builds up in the inlet 6 opening a non-return valve 10 to supply pressure liquid through the now open ports 8 and/or 9 to the cylinders of the hydraulic motors operating the implements. On the liquid attaining a pressure predetermined by the spring loading of the high-pressure valve 20, e.g. as would occur on the hydraulic motor completing its stroke, this valve will open so that liquid will pass through a passage 21 and the valve 19 to exhaust and also through the passage 17 to below the pistons 22 to return the piston valves 1, 2 to their neutral positions. Pressure liquid from the motor cylinders can then be exhausted at a controlled rate through spring-loaded, tubular regulating valves 32, on the raising of the valves 1, 2. Holes 27 in the pistons 22 permit the escape of entrained air in the liquid and prevent the operation of the pistons in the event of leakage of pressure liquid past the high-pressure valve 20 or past the valves 1, 2, whilst a leakage duct 29 from the valve 2 prevents untimely operation of the piston 22 associated with the valve 1 when that valve only is operated.

Abstract: 428,389. Parachutes. MULLER, W., 14, Waterloo-Ufer, Berlin. Nov. 13, 1933, No. 31602. [Class 4] Parachute apparatus for use at high initial velocities comprise two independently opening parachutes directly connected with the load, of which one has a surface less than 1/10th of the surface of the main parachute and is strong enough to withstand five to ten times the normal load. The auxiliary parachute opens first and minimizes the sudden deceleration caused by the opening of the main parachute. The parachute 3 and auxiliary parachute 7 are packed in a container 5 provided with a closure secured by pins connected to a rope 1 having extensions 2 which pass beneath the parachutes and are secured to the container by frangible connections. A pull on the rope releases the pins and ejects the parachutes. A pilot parachute 6 connected by a cable to the life line 12 may also be used, but it has an opening less than that of the parachute 7 and its cover may be formed as three-fourths of a sphere. The parachute 7 has a wood disc at the top with two flat springs 8 crossing at right angles and its shroud lines are connected to a rope 14 connected to the lower end of the line 12 which passes through the wood disc. The parachutes 3 and 6 may be placed in a separate rack in the container 5. A modification is described in which the auxiliary parachute 7, turned inside out, itself forms the container for the main and pilot parachutes, its cover having eyelets on its inner surface through which the closure pins are passed. The pilot parachute 6 may itself form the retarding device without the auxiliary parachute 7.
