IPC: B66C23/80
Filed: 1968-05-17
Abstract: 1,202,471. Stabilizing apparatus. HYDRAULISKA INDUSTRI A.B. 17 May, 1968, No. 23518/68. Heading B7J. In a vehicle having an hydraulically operated load handling apparatus 3, and provided with supporting legs 23, 24 on each side of the vehicle hydraulically lowerable to the ground, the pressure fluid for the load handling apparatus and for the supporting legs being supplied by the same fluid pump 16, a control valve 31 is connected between the pump 16 and an operating valve 10 for the load handling apparatus so that fluid pressure is transmitted to the valve 10 only when hydraulic pressure is supplied to the supporting legs 23, 24. Piston and cylinder devices 5, 6, 11, 12, for controlling the load handling apparatus 3 are connected via conduits 8, 9, 13, 14 to the operating valve 10. The supporting legs 23, 24 are each operated by a piston and cylinder device 21, 19 and 22, 20, supplied with pressure fluid through conduits 27, 28 and valves 29, 30. The control valve 31 comprises a spool valve 32 having a spool 33, and two cylinders 34, 35 coaxial with the spool 33 having a common piston 36, A bracket 46 prevents relative movement of cylinders 32 and 35, but cylinder 34 is slidable along the axis of the pistons, being urged to the left by the spring 51. A sleeve 40 attached to the cylinder 34 is connected to the spool 33 by means of a driving pin which passes through enlarged holes 44 in the sleeve 40 allowing some play. Movement of the piston 36 and cylinder 34 being limited by the rings 49, 50 on the piston. Conduits 64, 65 connect the cylinders 34, 35 to the cylinders 19, 20 of the supporting legs. The spool valve 32 has three annular grooves 56, 57, 58 on its inner surface and the piston 33 has a circumferential groove 59 of equal or slightly greater length than the spacing of the grooves, groove 57 being connected to the fluid pump 16, groove 58 to the operating valve, and groove 56 providing a return path for fluid to a reservoir 15 via a throttling valve 62. When the pump is operated the pressure buildup due to the throttling valve 62 is sufficient in the conduits 27, 28, if valve 29 is open, to lower leg 23. Fluid pressure will be transmitted via conduit 64 to cylinder 34, moving it to the right against the spring 51. No movement is transmitted to spool 33 due to the lost motion in the connection of sleeve 40. If valve 30 is now opened, leg 24 will be lowered and fluid pressure transmitted to cylinder 35 forcing the piston 36 and hence cylinder 34 to the right, causing spool 33 to move to connect grooves 57 and 58, thus allowing pressure fluid to reach the operating valve 10.

[Also in Division B8] Moulds for forming ice lollies are introduced into freezing tank 1 at 6 up slope 16 into the compartment 27 of a shuttle 25. Shuttle 25 has two additional compartments 28 and 29 which have been previously filled with mould. The shuttle 25 carrying the three moulds is moved one step forward by fluid cylinder 35 so that compartments 27, 28, 29 come respectively opposite lanes 9, 11 and 13 of tank 1. Fluid cylinder 39 then operates to cause pusher 31 to move forward and advance the three moulds into the respective lanes. This causes the moulds in said lanes all to advance by one step so that the leftmost mould in the lanes 9, 11 and 13 pass into the compartments respectively 22, 23 and 24 of shuttle 20. The shuttle 20 is then displaced one step forward by fluid cylinder 34 to bring the three moulds respectively into the position shown opposite lanes 10, 12 and 14. Fluid cylinder 38 then operates to cause pusher 30 to displace the three moulds down the said lanes and so cause each mould in the lanes to be displaced rightwards by one step, and the rightmost mould in lane 14 to be discharged from the tank at 33. The cycle of operations is then restarted.

Class 135 [Also in Group XXXIV] A hydraulic control valve, e.g. for aircraft brakes or flaps, comprises a housing 1 with connections 10, 11, 12, to exhaust, the brakes or other mechanism, and a source of pressure respectively, a ported liner 6 in a bore 2 in the housing, a sleeve 13 slidable in the liner and having ports 16a ... 16c and recesses 15a .. 15c permitting communication of the connections 10, 11, 12 with the interior of the sleeve, a piston valve having lands 24, 25 slidable in the sleeve and movable manually against a spring 31, and a loading spring 30 for the sleeve. Movement of the piston valve to the right by a stem 28 first closes ports 16a and then opens ports 16c connecting the pressure source to the brakes. Pressure builds up in the connection 11 and acts through bores 22, 23, on a piston 18 which moves the sleeve 13 against the spring 30 to close the ports 16c. Increased braking is obtained by moving the piston valve further to the right. Leakage past the valve collects in a chamber 3 and thence passes through a bore 32 in the piston valve to the recess 15a and the exhaust connection 10. An increase of pressure in the connection 11 due, e.g. to a rise in temperature, causes the piston 18 to move the sleeve to open the exhaust ports 16a to relieve the excess pressure. When the stem 28 is released, the springs 30, 31 move the sleeve and piston valve to close the ports 16c and connect the brakes to exhaust.
