Title: Gas storage
Inventor: HALENE CLEMENS
IPC: F17C11/00
Filed: 1983-06-23
Abstract: The invention relates to pressure gas container apparatus broadly of the type described in our Patent Application No.82 18303 (Serial No. 2103348) in which radially directed partition sheets are provided at intervals around a central gas pipe. The block (1) of storage material disclosed herein when installed, defines a cavity (3) adjacent the gas pipe (5), into which the blocks swells as the container apparatus is filled. This results in the block having a density differential between its radially inner and outer extremities which results in various benefits. In addition to reducing the risk of distortion or other damage to the apparatus as it is filled, gas flow to and from the gas pipe (5) is enhanced as is the heat transfer between the container wall and the block (1). The size of the cavity (3) preferably corresponds to at least to 5% of the net volume of the compartment of the storage container in which it is located. <IMAGE>

Title: Open centre unloading valve
Inventor: JACKSON ALAN DAVID
IPC: F15B13/02
Filed: 1987-02-03
Abstract: An unloading valve 10 is utilized in an hydraulic system in conjunction with a conventional open centre control valve 14 having an open centre passage 18 and a dead end power passage 20. The unloading valve 10 is supplied by a system pressure from a pump 12 and divides the pump flow into two paths in a set proportion regardless of the amount of flow or pressure levels in either flow path. One flow path is directed from port 44 through line 28 to reservoir 22 with the other flow path directed through line 26 to the open centre passage 18 in the directional control valve 14. The dead end power passage 20 of the control valve is separately provided with system pump pressure in a parallel path via line 24. The valve 10 has a hollow spool 34 with inlets 36 and outlets 38, 40 in the ends. Because orifices 38, 40 have different sizes the spool position is not centred; the flow to port 44 is approximately 70% of the total in the example. Thus, when the valve 14 is in neutral position only a minor portion of the pump discharge passes through open centre passage 18. <IMAGE>
