Title: Pilot-controlled apparatus for the load-independent regulation of a pressure medium flow in proportion to an electric input signal
Inventor: HEISER JOACHIM DIPL ING
IPC: F15B13/043
Filed: 1981-10-10
Abstract: The invention proposes a pilot-controlled apparatus (10) for the load-independent regulation of a pressure medium flow in proportion to an electric input signal, which apparatus at the same time permits pressure control using a single electrohydraulic pressure regulating valve (36). A throttle valve (18) hydraulically pilot-controlled by the pressure regulating valve (36) has a valve body (27) which is coupled to an electromechanical displacement sensor (39) and is connected to a position control circuit via an electric device (42) which controls a proportional magnet (37) of the pressure regulating valve. By returning the load pressure from the outlet (13) to the regulating valve (16) of a variable displacement pump (14), the return being controllable by the throttle valve (18), the pressure difference across the throttle valve (18) is held constant, with the result that its position-regulated valve body (27) regulates the pressure medium flow independently of load. Additional pressure limitation is possible by electrical limitation of the set point signal and by virtue of the pressure regulating valve (36) which exercises pilot control. <IMAGE>

Patent DE-3200884-A1 (DE)
Title: Combination projector
Inventor: WANNERT MICHAEL
IPC: G03B21/132
Filed: 1982-01-14
Abstract: The invention relates to a combination projector which is suitable for projecting writing foils and opaque objects. It is a patent of addition to the main application P3107163.5, whose essential components are an improvement in manipulation and a saving in structural parts, and which simultaneously aims for a higher image brightness. The invention is characterised in that the projection head (4) is mounted rotatably on a column (2) and auxiliary column (3) as well as on the housing (1), as a result of which the latter remains horizontal during swivelling to the opening (6) for episcopic projection. A spring neutralises the weight. At the same time, the cylindrical concave mirror (11) is rotated via the rod (13) and the lever (14), so that the light of the discharge lamp falls onto the picture copy (23). Before the projection head reaches the opening and snaps in, the sealing cap (7) is opened via the tilting lever (8) and the cam (20). A rubber diaphragm (5) prevents scattered light. The advantages are: good didactic manipulation and a cost-effective, fast projection device, since in each case only one mirror, discharge lamp, ballast and lens are required to produce it. <IMAGE>

Title: Process for shaping, punching and stacking articles made of thermoplastic film and apparatus for carrying out the process
Inventor: KIEFER GUENTHER
IPC: B29C51/44
Filed: 1982-01-28
Abstract: The invention relates to a process for shaping, punching and stacking articles made of thermoplastic film and an apparatus for carrying out the process. The articles are thermoformed by differential pressure with the aid of a mould, punched out in the apparatus and then transferred into a stacking magazine. The shaping, punching and, in particular, stacking should be performed in such a way that, at a high cycle rate, moulding with compressed air and, if appropriate, shaping with stretching aids is possible, without large masses having to be moved during each cycle. The expenditure on moulds and displacing device should be low. This is achieved by the articles being transferred after shaping and punching-out into a slide which can be moved over the actual mould perpendicularly to the ejecting direction, by the said slide being displaced until under stacking magazines arranged to the sides of the moulds and by these articles then being pushed into these stacking magazines. <IMAGE>
