Title: Apparatus for raising and lowering aircraft arrest devices
IPC: B64F1/02
Filed: 1970-11-19
Abstract: 1335835 Aircraft arresting gear BORGS FABRIKS AB 19 Nov 1970 [4 Dec 1969] 54957/70 Heading B7G Apparatus for arresting an aircraft comprises a pylon 1 and first and second fluid actuated motors connected thereto, the first motor 4 being adapted to lift the pylon 1 quickly and the motors being so connected thereto that the first and second motors respectively exert their smallest and greatest moments when the pylon is in its lowered position so as to exert a force restraining the pylon in that position, the first motor being more powerful than the second. Fig. 1 shows the apparatus ready for lifting the pylon wherein pressure fluid in the pressure side 6 of the piston of motor 4 urges the piston to move, but substantially no torque is produced about the pivot 2 of the pylon because the line of action of the motor passes through the pivot. At the same time pressure fluid is applied to the piston of the motor 5 to produce a small downward movement on the pylon, which may be balanced by a counter-weight 3. To lift the pylon, the valve 12 is switched electrically, Fig. 3, to supply fluid to the pressure side of piston 5, thus raising the pylon slightly and hence displacing the line of action of the motor 4 relative to the pivot 2 and allowing the piston of the motor to extend and raise the pylon, the motor 4 being supplied with fluid from an accumulator 7. Pressure in the fluid is maintained by a pump 8 driven by an electric motor and connected to the valve 12 by a conduit 11 and a non-return valve 13. During lifting the pylon, a fast rate of flow of pressure fluid to and from motor 4 is facilitated by the large size of a line 14 connecting the motor to the accumulator 7, and of the line 15 connecting the motor to a reservoir 17. To lower the pylon the valve 12 is switched so as to supply pressure fluid to the drag side of the motor 5 to pivot the pylon and also to connect both sides of the piston of motor 5 to the reservoir 17, the restriction 18 preventing fast flow through the line 14 and hence smoothing the lowering operation. The motors may be single acting, in which case separate means are required to lower the pylon. There may be more than one of each motor coacting. The second motor 5 may be connected to the pylon 1 by mechanical links (19), Figs. 6, 7 (not shown), which may be lockable (20) Fig. 8 (not shown) to prevent lifting of the first motor until the second motor is actuated. The initiation of the raising and lowering of the pylon may be automatic, for example actuated by trip battery 16.

Abstract: 1354958 Anchor nuts and bolts PALAR (CURACAO) NV 3 Dec 1971 [28 Dec 1970] 56367/71 Heading F2H An anchor means 10 comprises an internally threaded load bearing member 20, which may comprise a separate sleeve and two expansible members 18, 19 located around a reduced diameter portion 17 of a shank 11. On insertion of the shank 11 in a hole 12, members 18, 19 positively engage the hole wall and subsequent partial removal of the means 10 expands the members 18, 19 over a tapered portion 16 of the shank 11 thereby causing anchoring. Possible accidental removal of the anchor means 10 by repeatedly alternating the direction of the load force is prevented by, for example, ratchet teeth 41. The teeth 41 are directed so as to engage the members 18, 19 during tensile loading. In modifications, accidental removal is prevented by cup springs (Fig. 6, not shown), a nut (Fig. 7, not shown) or by a threaded sleeve (Fig. 8, not shown). These modifications function by exerting a tensile force, which anchors the members 18, 19 in position, which is greater than the compression force exerted by a load. The anchor means 10 may comprise ribs 24 which engage in the hole 12 so as to prevent rotation.

Abstract: 1434190 Valves LANDON KINGSWAY Ltd 22 Nov 1973 [12 Dec 1972] 57181/72 Heading F2V A valve having facilities for monitoring for leakage between the closure surfaces comprises two closure members 13, 14, which engage two seats 22, 21 respectively in the valve closed condition and form a chamber 17, which is evacuated automatically as the valve closes, to which is connected a pressure sensitive switch 23. Closure member 13, which has a sealing ring 19, is integral with an operating stem 18 and closure member 14 of reinforced rubber sealingly slides on the stem. Springs 15, 16 urge the two closure members towards their respective seats. In closing the valve closure member 14 contacts its seat 21 and closure member 13 moves upwards until it contacts seat 22 forming the chamber 17 between the two closure members. By virtue of the seal between closure member 13 and the bore in which it works, the chamber 17 is evacuated as it is formed. Any pressure rise in this chamber, due to leakage between the closure surfaces can thus be detected by the pressure sensitive switch 23 which operates an audible or visual alarm.

Title: Unloader valv3
IPC: B60T13/14
Filed: 1972-12-20
Abstract: 1415876 Valves; fluid-pressure brakes AISIN SEIKI KK 20 Dec 1972 [24 Dec 1971 22 Sept 1972] 58937/72 Headings F2V and F2F An unloader valve for use in an hydraulic power brake system comprises a housing 10, Fig. 1, divided into chambers C 1 , C 2 , C 3 , a spring 31 urging a ball valve 50 against a seat 23, and a ball 70 held against one end of a plunger 40 by a spring 71. In use, fluid from a pump P is supplied to the chamber C 1  through a duct 2. The fluid leaves the chamber through a duct 4 and passes through a valve 5 to accumulators A 1  and A 2  of actuators B 1  and B 2 . The pressure in the accumulators is supplied to the chamber C 3  through a duct 7. When the pressure in the chamber C 1  has been built up sufficiently, the ball 50 is lifted from its seat and the fluid from the pump flows into a reservoir R. As a result of the reduced pressure in the chamber C 1 , the pressure in chamber C 3  acting on the end face of the plunger 40 causes the plunger to move downwards to compress the spring 31. The fluid acting on the end face of plunger 40 is effective over a cross-sectional area D 2 , Fig. 5. However, with continued movement of the plunger, the ball 70 engages a seat 62 and the effective cross-sectional area on which the fluid in chamber C 3  acts is increased to D 3  so that the ball valve is held open by an increased force. When the actuators B 1 , B 2  are deployed, a consequential reduction of pressure in chamber C 3  causes the ball 70 to lift off its seat 62, thereby reducing the effective cross-sectional area from D 3  to D 2  and thus ensuring rapid seating of the ball valve 50. The valve S comprises two ball valves 108a and 108b, Fig. 2, which are lifted off their seats by fluid entering through an annular chamber 121. End chambers 103a and 103b are connected through ducts 5 and 6, Fig. 1, to the actuators. Pressure in the end chambers is balanced by a ball valve (123), Fig. 3, not shown, which co-operates with two opposed seats (127) and (128) to allow the higher pressure fluid to be fed through duct 7, Fig. 1, to the chamber 3. In a modification of the invention, Fig. 7, the plunger 40A is made hollow so that the chamber C 1  communicates with the chamber C 3  through the lifting of the ball 70. The action of the valve is otherwise as before.
