    摘要: A bulkhead is formed of a sheet of material which is preformed so as to have alternatingly opposed S-shaped creases at spaced intervals which define pairs of mutually facing recessed grooves between adjacent creases. Resilient surface area enlarging members are each provided with a pair of lips formed on the opposite edges thereof. Each pair of lips are received within a pair of mutually facing recessed grooves of the bulkhead. The surface area enlarging members can be snapped into or out of operative position with respect to the bulkhead to adjust the surface area of the device.

    摘要: A hydraulic device comprising at least two cylinder-piston assemblies. Each of the assemblies are of the double-action type with a front and rear chamber on either side of a piston. The chambers are connected in series in a hydraulic control circuit such that the front chamber of a first assembly has a direct connection to a rear chamber of a second assembly. At least one of the cylinder-piston assemblies is provided with a valve assembly which opens a bypass thereby bypassing the piston of the assembly when the piston is situated close to the direct connection at the end of its stroke and the effective piston surfaces are the same in the chambers mutually connected by the direct connection.
