Title: Method and device for prefilling a pump
Inventor: ESKOFIER WILFRIED
IPC: F04B53/12
Filed: 1982-12-28
Abstract: For prefilling a pump chamber of a cyclically operable dosing or atomising pump of a container filled with filling material and closed by the pump, it has already been proposed to open an outlet valve by means of a pump pressure stroke and to bring into effect, through the open outlet valve, a subatmospheric pressure which conveys filling material into the pump chamber, before, via a subsequent suction stroke, the pump chamber is more extensively filled. In particular in the case of gel-like filling material, this is expedient in order that, for discharging a dosed filling material quantity, a series of pump strokes does not first have to be carried out, but the pump delivers already during the first pump pressure stroke. In the method proposed, the subatmospheric pressure is controlled temporally in such a manner that it is already reduced before the outlet valve of the pump is closed. The result of this is either an incomplete prefilling of the pump chamber or too strong a filling, that is to say an overflowing of the filling material via the outlet valve. According to the invention, these disadvantages are eliminated by the action of the subatmospheric pressure in the pump chamber being ended only by the closing of the outlet valve and the subatmospheric pressure being maintained beyond the closing of the outlet valve at least over a part of the suction stroke of the pump.

Title: Hydraulic cylinder with internal displacement conversion
Inventor: LUHMER HORST DIPL ING DR
IPC: G01D5/165
Filed: 1983-07-14
Abstract: The simple inexpensive and proven method of converting the displacement via a linear potentiometer which is attached to the cylinder head and is felt by a slider attached to the piston has hitherto been obstructed by the fact that there must be protection against twisting on the piston or on the piston rod to ensure a permanent slider contact. According to the invention, this problem is eliminated by a bearing disc which is arranged axially undisplaceably but rotatably in the piston by means of which the linear potentiometer is carried through centrally axially displaceably but untwistably, the slider being mounted on the bearing disc. The cylinder can thus be installed in any desired way without having to take into consideration protection arrangements against twisting.

Patent DE-3403723-A1 (DE)
Title: Solid fitting, preferably a furniture knob, which consists of plastic and can be mounted on the outside of a furniture part, in particular a drawer, a door or the like
IPC: A47B95/02
Filed: 1984-02-03
Abstract: Furniture knobs consisting of plastic are produced in an uneconomic manner by cutting from rod material. According to the invention, it is proposed that the knob is formed from a core 4 and a coating which surrounds the latter at least on the visible surface, both the core 4 and the coating 5 being injection-moulded in successive operations. The dimensions of the core are smaller by a relatively small amount than those of the fitting so that the shape of the core is similar to the shape of the fitting. As a result, the coating 5 is relatively thin and, in a particularly advantageous manner, has an even thickness to achieve a smooth surface. Finishing work, such as polishing, which increases the surface quality is therefore superfluous in a furniture knob produced by the method according to the invention. <IMAGE>

Title: Pressure transducer for a hydraulic system
Inventor: PASSEKEL EDWIN ING GRAD
IPC: F15B7/08
Filed: 1984-10-04
Abstract: The pressure transducer for a hydraulic clutch system of a motor vehicle contains a working piston axially displaceable in a cylindrical working chamber as well as an after-suction valve which is arranged between the working chamber and a follow-up tank and is in operative connection with the working piston in such a way that its valve member is positively lifted from the valve seat when the working piston assumes a defined initial position (neutral position). So that the hydraulic clutch system can be bled quickly and simply by the so-called vacuum method during assembly of the vehicle and can at the same time be filled with hydraulic fluid, an automatically releasable axial stop is fastened positively or frictionally to the working piston at the factory, by means of which stop the working piston is locked in its defined initial position by bearing against the housing of the pressure transducer until an actuating force acts on it for the first time via the piston rod, which actuating force corresponds at least approximately to the maximum operational actuating force. <IMAGE>
