Title: Improvements in hydraulic control valves
IPC: F15B13/02
Filed: 1962-08-16
Abstract: 985,950. Valves. HYDRAULIC UNIT SPECIALTIES CO. Aug. 16, 1962 [April 30, 1962], No. 31476/62. Heading F2V. [Also in Division G3] An hydraulic control valve has a body with an inlet 18, Fig. 1, an outlet 22, a pair of service passages 13, 14, Fig. 2, connectible with a reversible hydraulic motor, a spool 12 slidable to either of a pair of operating positions at each of which one service passage communicates with the inlet while the other communicates with the outlet, a U-shaped return fluid passage 33, and a check valve 42 which opens a by-pass 41 when the pressure in the return fluid passage 33 is higher than that in the service passage connected to the inlet. Cavitation during rapid operation of the motor by its load is thus prevented. In the preferred embodiment, two spools 12 for parallel or series-parallel operation of a pair of motors are mounted in separate parts 8, 9 of a body of sectional construction, and in their neutral position, permit fluid from the inlet to flow direct to the outlet through an open-centre passage 21. Movement of one of the spools to an operating position causes fluid from a feeder passage 26 to flow through a check valve 29 and a bridging passage 27 into one of the service passages, the other service passage being connected with the return fluid passage 33 which communicates with the outlet 22 through restrictions 37 and an exhaust manifold 32. The restrictions 37 raise the pressure in the passage 33 during rapid operation of the motor to ensure opening of the check valve 42 which has an annular shoulder 50 subjected to this pressure and a hollow interior accommodating a loading spring 48 and subjected through a port 49 to the pressure in the inlet service passage. Decreasing pressure in the latter opens the valve further so that a constant pressure drop from the passage 33 is maintained. In a modification, the passage 33 is connected to the manifold 32 by a valve 137, Fig. 4, which is identical in construction with the valve 42 and replaces the restrictions 37. Moreover, the valves 42 may be replaced by combined check and high pressure relief valves 70 of the type described in Specification 960,533 or a combined valve of the type described in Specification 950,131 may be used in place of the valves 42 and 137.

Abstract: 1,091,858. Automatic storage systems. FERRANTI Ltd. July 14, 1966 [July 24, 1965], No. 31652/65. Heading B8E. An automatic storage system, Fig. 1, comprises storage bays arranged in rows of columns on both sides of aisles A, B, C, conveyance means adapted to convey goods via the columns between a loading station P and an unloading station D, and a stacking crane (shown by the shaded rectangle) adapted to travel past the columns and to transfer goods between the conveyance means and the storage bays. The crane runs on rails and the conveyance means may be formed by conveyer belts disposed between the rails; switch points B1, B2, C1, C2 are provided for the rails and diverters are provided for transferring goods between belts. The crane moves from one aisle to another, travelling in opposite directions in adjacent aisles, and may run to either station P or D for maintenance purposes; it includes means for checking whether a storage bay is empty or full. The system is controlled by a computer, Fig. 2 (not shown), comprising a memory and means for feeding into the memory the identity of goods disposed at any instant in each occupied storage bay. In operation goods arriving at the station P are identified by an operator who feeds this information to the memory and places the goods on the conveyer. The goods are carried to the aisle in which the crane is operating and their storage bay location is signalled by the crane to the memory to be associated with the identity of the goods. When goods have to be withdrawn the crane is signalled when it reaches the correct location and the crane withdraws the goods and places them on the conveyer. The computer may arrange a list of items to be withdrawn to give the most efficient withdrawal sequence and may keep a continuous stock record of goods stored; it may direct goods direct from the station P to the station D if so required. The conveyance means may be formed by one or more trucks running on the same rails as the crane, between the latter and the stations P, D; the crane may have a provisional store or magazine for holding goods while the trucks are away. The crane may be supported on ground level rails (as shown) or run on an overhead gantry, or on one ground level rail and one overhead rail. The conveyance means may be disposed to one side of the rails. Trip switches or proximity devices may be used to indicate the position of the crane.
