Title: Insert for subdividing show cases, display stands or the like
Inventor: MEISSNER KLAUS DIPL ING
IPC: A47B87/02
Filed: 1984-07-18
Abstract: In known display stands, intermediate shelves, which rest on supports attached to the display stand, have to be inserted to subdivide a receiving space. These supports have to be provided by the factory on or in the vertical side surfaces of the display stand specifically for the object and thus restrict the possibilities of use of a display stand. In order to allow subdivision of a receiving space in a display stand without constructional modifications to the display stand, provision is made for two vertical walls extending in the insertion direction to be provided which are kept spaced apart by a bearing plate lying at right angles to the walls and which are firmly connected to the bearing plate. In this case, the upper edges of the walls form resting surfaces for the lower edges of the walls of an insert to be placed on. The inserts are prevented from slipping away from one another laterally by a guide arrangement provided between the upper edge of the lower insert and the lower edge of the upper insert.

Title: Circuit arrangement for setting up conference links
Inventor: KOPETZKY HORST DIPL ING
IPC: H04M3/56
Filed: 1984-07-25
Abstract: In a circuit arrangement for setting up conference links in which the transmission signal which has the highest instantaneous value and which is transmitted by a subscriber station involved in the conference link is in each case identified by an evaluator and only this transmission signal is sent to all the other conferees, the subjective impression is created that not all the conferees could talk to one another simultaneously. To evoke the impression of a natural conversation, using the result signals output by the evaluator (B), the through-connection of the transmission signals of at least the subscriber stations (TA1, TA2, TA3, TAn) is initiated to the other subscriber stations which had previously supplied the highest instantaneous value. <IMAGE>

Title: Hydraulic control device for the mould clamping unit of an injection moulding device
Inventor: TITTMANN EGON DIPL ING
IPC: B29C45/67
Filed: 1984-08-25
Abstract: A hydraulic control device (10) for the mould clamping unit (11) of an injection moulding machine is proposed with which the pressures, in a toggle cylinder (14) and in a pressure cylinder (21) serving as pressure pad, which are necessary for securing the mould can be precisely controlled. The pressure pad (22) can be relieved to the tank (54) parallel to the controlling directional control valve (58) via a pressure control cartridge (68) opened by spring force, a mould-securing pressure valve (77) serving for pilot control. The mould-securing pressure valve (77) can be activated via a control valve (79) which is allocated to a control loop (38, 75, 78, 81) and also controls a pressure feed line (83), via which, when the mould (18, 19) is locked, a compression volume can be fed to the pressure pad (22), bypassing a proportional throttle valve (36), the pressure of which pressure pad is governed by a mould-locking pressure valve (65). In the last third of the closing stroke, a proportional pressure control valve (41) determines the mould securing via the pressure in the toggle cylinder (14), whereas when the toggle (15) is extended, the mould-securing pressure valve (77) controls a fine mould-securing pressure of close to 0 bar in the pressure pad (22). Subsequently the mould-locking pressure valve (65) regulates the maximum mould-locking pressure, whereas, on decompression, the proportional pressure control valve (41) controls the smooth pressure release. <IMAGE>

Patent DE-3508057-A1 (DE)
Title: Bearing arrangement
Inventor: MAURER FRIEDEL
IPC: F16C9/02
Filed: 1985-03-07
Abstract: A bearing arrangement with a radial sliding bearing and at least one axial sliding bearing, in which the axial sliding bearing has at least one semicircular thrust-wahser segment, can be considerably improved as regards the assurance of screwing in the axial sliding bearing elements the right way round if the radial sliding bearing projects with an annular axial rim region beyond the basic bore of the bearing housing and thereby forms a radial contact shoulder for the thrust-washer segment. At one end region, the thrust-washer segment is given a radially inward-projecting locking hook which can be introduced into a rim recess on the annular rim region of the radial sliding bearing. As a result, it is only possible to screw in the thrust-washer segment completely with its end free of the locking hook to the fore and only from that side of the bearing arrangement on which the radial sliding bearing has its rim recess. In this bearing arrangement, the full width of the basic bore in the bearing housing and furthermore a narrow rim region on each side is available for the width of the radial sliding bearing. As a result, this bearing arrangement is particularly suitable for narrow bearing locations and highly loaded bearing locations for small-diameter shafts.
Patent DE-3509797-A1 (DE)
Title: Tracheal tube with double-balloon blocking for intubation anaesthesia
Inventor: EIKE RAINER
IPC: A61M16/04
Filed: 1985-03-19
Abstract: In order to ensure reliable endotracheal intubation anaesthesia there is required a tube which blocks automatically when the blocking system fails or can be blocked manually. In the commercially available tubes re-intubation is necessary if the blocking balloon fails, and this is not possible in every type of operation. In addition, re-intubation is also a renewed risk for the patient. Using the double-balloon tube provides a system which offers optimum anaesthetic security for physician and patient because, when a balloon fails, there is a second balloon which seals the gap between the tube and the trachea again and thus rules out penetration of blood and secretion into the lungs. The double-balloon system can be transferred to any type of tube used for tracheal intubation. Anaesthetic incidents due to a defective blocking balloon are therefore ruled out. <IMAGE>
Patent DE-3514746-A1 (DE)
Title: Contact lens of elastic material for far seeing and near seeing
Inventor: ZAPLETAL FRITZ
IPC: G02C7/04
Filed: 1985-04-24
Abstract: The invention is applied in the field of correcting visual inadequacies, in particular presbyopia. A contact lens is proposed whose elasticity suffices for being compressed by the pressure of the upper and lower lids. In turn, the compression adapts the contact lens to the refractive power requirements for far seeing by presbyopes. The attached drawing shows, on the one hand, a side view of an elastic contact lens, located on the eye, in use for far seeing (Fig. 1). A further drawing represents, in the same view, the same contact lens in the case of near seeing. The upper and lower lids compress the lens. In this way, it becomes suitable for near seeing in presbyopes (Fig. 2). <IMAGE>

Title: Cathode bottom for aluminium electrolytic cells
Inventor: WILKENING SIEGFRIED DR ING
IPC: C25C3/08
Filed: 1985-10-25
Abstract: The carbon cathodes used in the molten-salt electrolysis of aluminium and the sidewall linings made of carbon are porous. Electrolyte components (vapours and low-melting eutectics) penetrate through the carbon material into the adjoining refractory material of the cell lining. The results, inter alia, are high heat losses, early break-down of the lining and considerable losses of cryolite and furnace additions. The cathode bottom according to the invention prevents the penetration of the refractory material and facilitates crust formation for protecting the sidewall lining. This results in prolonged useful lives and considerably reduced specific energy consumption for the electrolysis. The underside of the cathode blocks (1) made of carbon material is covered with a closely fitting cast-iron layer (5) as a penetration barrier which is permanently connected to the current-supplying steel cathode busbar (3). The cathode bottom is designed in such a way that a triangular or similar cross-sectional profile of the aluminium is formed, the depth of the bath increasing from the longitudinal sides to the centre of the pot. This can be achieved by fitting the cathode blocks in a tilted position, by inserting continuous blocks having preformed recesses or by cementing appropriately formed carbon bodies onto the cathode blocks.
