Abstract: In a previously proposed corresponding device, two-handed operation is required and the application of the device is limited. The further developed device is intended to allow single-handed operation and to be usable for further applications. The new device has a housing (6), constructed as a hand-held grip body, in which housing at least the pump (1) with its drive motor (5) is accommodated, a flexible suction hose (30) being connected to the pump (1) on the suction side. In this case, provision is preferably made for there to be arranged in the housing (6) a speed regulating device (17) for the motor (5) of the pump (1) having an actuating member (35) which allows alteration of the speed of the motor (5) by the hand holding the housing (6) on the outside of said housing. The device can be operated with one hand and is thus easy to handle. With its exchangeable liquid discharge members, it is versatile in use, for example for purposes of hair treatment and care or for care or medicinal treatment of the skin. <IMAGE>

Abstract: An electrohydraulic servo system which includes one or a plurality of pressure compensated flow control servo valves (12, 14) for feeding hydraulic fluid from a variable displacement pump (16) to associated actuators (18, 20) and loads (1, 2). A closed-loop velocity-control servo system (22, 24) is coupled to each servo valve (12, 14), and is responsive to velocity command inputs (V1, V2) from an operator (26) and to feedback signals (Y1, Y2) from the respective loads (1, 2) for providing flow control signals (U1, U2) to the respective servo valves (12, 14). A pump controller (36) receives the valve flow control signals (U1, U2), derives associated valve vlow signals (Q1, Q2) from predetermined functional characteristics of the pressure compensated valves, and obtains a total flow demand (Qc) as a function of the sum of the indicated individual valve flows. A pump displacement command (Dc) is derived as a combined function of total flwo demand (Qc) and pump speed (N) to accommodate volumetric inefficiencies which vary with speed (N), and the displacement command signal (Dc) is fed to a pump displacement servo control loop (60) for controlling pump output. Displacement command (Dc) is limited (at 50, 52) as a function (NL) of power available at the engine coupled to the pump to prevent engine stall.

Abstract: In order to secure the outer vessel (2) of double-walled vacuum-insulated storage tanks for low boiling liquefied gases against an increase in pressure in the insulation space in the event of failure of the vacuum, valves are used which consist of a valve housing (1), mounted in the outer vessel, a sealing plug (3) and an O-ring (4), as the sealing element. The O-ring is deformed exclusively in the axial direction by the pressure difference between the atmosphere and the vacuum and an additional spring force. This valve is little suited to small vessels, inter alia because of the relatively large structural volume resulting from the spring. In a valve which is particularly suitable for small vessels, the O ring is thus deformed radially and, at the same time, axially, exclusively under the influence of the external air pressure, as a consequence of the dimensions of the valve housing and the sealing plug.

Abstract: A method of controlling a hydraulic press wherein changing over from velocity control to pressure control can be effected at an optimum point of time in accordance with a condition of material being filled. When a movable mold half of a metal mold is moved by a hydraulic cylinder to compression mold a work within a cavity defined in the metal mold, the velocity of movement of the mold half by the hydraulic cylinder is controlled until pressurization of the work is started, but after starting of the pressurization, the pressurizing force of the hydraulic cylinder is controlled. During the velocity control, a parameter which varies as the compression proceeds is successively detected during the velocity control, and changing over from the velocity control to the pressure control is effected at a point of time when the detected parameter coincides with a preset value, that is, when the work is fully filled in the cavity. A device for controlling a hydraulic press is also disclosed wherein optimal pressure control can be assured in accordance with a current condition of material for molding.

Abstract: The screw type vacuum pump comprises a pump casing (1) having a suction inlet (14) and a discharge outlet (15), and a pair of rotors (4, 5) incorporated within said pump casing and meshing with each other to rotate in synchronised manner. The vacuum pump evacuates a reaction vessel, to which process gas is applied, to obtain a negative pressure condition of a predetermined level. On the operation of the pump, inert gas is introduced into a compression working chamber (6c) directly or through a sealing portion (17B, 18B) disposed adjacent the discharge outlet. The introduced inert gas is adiabatically compressed therein to generate heat to heat the rotors and a casing wall. Further the inert gas effects a reduction of partial pressure of the process gas in the pump. Accordingly side reaction product is prevented from accumulating on the rotors and the casing wall.

Abstract: The object of the invention is to allow cooling emanating from the hollow space of the bent roller to be transferred evenly onto the outside of the expander roller. For this purpose, the hollow spaces inherent in the design are filled by a conductive material, preferably aluminium, in the form of a moulded part adapted exactly to the shape of the respective hollow space. This configuration achieves not only a more uniform cooling on the outside but also an approximately even film of condensate between the expander roller and the material to be dried. This film of condensate serves as a parting line between the expander roller and the material to be dried. <IMAGE>
