Title: Mounting of a window pane in a vehicle
Inventor: WOELKER HUBERT
IPC: B60J10/00
Filed: 1987-08-13
Abstract: The invention relates to the mounting of a window pane (5) in a frame (3) by means of an elastic profile strip (4) which is clamped in a first longitudinal groove (6) onto a flange (2) of the frame (3) and in a further longitudinal groove (7) holds the edge region of the window pane (5).

Patent DE-3730370-A1 (DE)
Inventor: ORTMANN HELMUT DIPL ING
IPC: F42B14/06
Filed: 1987-09-10
Abstract: The invention relates to a method for manufacturing a sabot projectile and to a sabot projectile manufactured by this method, in which a thin uniform layer of rubber is coated onto the rear gas-pressure receiving surface in a vulcanising tool with an injection mould for the purpose of fixing the individual sabot segments together and sealing them off from one another. 
<??>During the injection of the liquid sealing material into the injection mould, there is a danger that, as a result of the high pressure prevailing during this, sealing material will penetrate in an uncontrolled way into the cylindrical inner annular gap between the sabot and projectile body. 
<??>This can lead to considerable impairment of the separation behaviour of the sabot segments and to a reduction of the target-diagram quality. 
<??>According to the invention, this disadvantage is eliminated in that, before the sabot projectile is inserted into the vulcanising tool, the rear annular gap between the sabot and projectile body is sealed off by the application of a sealing means on the circumference of the projectile body. A sabot projectile manufactured according to the invention is characterised by a sealing ring (22) arranged in front of the rear annular gap between the sabot (12) and projectile body (11) and vulcanised into the rubber coating (19) applied to the rear gas-pressure receiving surface (18) of the sabot (12).

Title: Piston/cylinder arrangement for hydraulic systems
Inventor: DOHRMANN WOLGANG
IPC: B60T11/16
Filed: 1987-09-12
Abstract: Piston/cylinder arrangement for hydraulic systems, in particular for motor vehicles, in which the piston is sealed off from the cylinder wall and is acted upon on one side by hydraulic fluid and is connected to an actuating rod. The actuating rod should be developed in such a way that not only is insulation from shocks and vibrations achieved but an electric switch is additionally actuated upon actuation of the piston by admission of pressure to the actuating rod. To this end, the actuating rod consists of two parts in the axial direction which are held firmly and in an axially movable manner relative to one another via an elastic connection, and the elastic connection has an electric switch.
Patent DE-3731448-A1 (DE)
Title: Piston turbine
Inventor: WUERTH GUSTAV DR
IPC: F02B3/06
Filed: 1987-09-10
Abstract: The present piston turbine is a further development of the slide-piston rotary compressor described in Laid-Open Specification DE 3714791 A1 and of the slide-piston internal-combustion engine already mentioned therein. The compressed gases (air) are passed via the outlet branch into a combustion chamber or antechamber or the like that can be closed at the front and rear by closure devices. When the piston passes the chamber outlet, the compressed gas is ignited, or injected if using the diesel principle. The gas then propels the piston up to about 320 degrees around the shaft to the turbine outlet, where it escapes, or sucks in fresh gas when the piston rotates further. However, it is more expedient to have two turbines working on each shaft, with one of the turbines functioning only as a compressor, and the other only as a combustion turbine. Both turbines are connected to one another correspondingly by the combustion chamber. Then two combustions of about 320@ each occur during a rotation of the piston, i.e. smoothly for the turbines and without great loads on the bearings.
Patent DE-3736630-A1 (DE)
Title: Combustion method
Inventor: SYASSEN ONNO DR ING
IPC: F02P15/00
Filed: 1987-10-29
Abstract: Diesel engines which have to operate with a relatively low compression ratio and with fuels with a relatively low cetane number have ignition problems during cold starting, when operating with a cold engine and when under partial load, with the consequence of high emissions of noise and noxious substances. By combining fuel injection with preinjection and with spark ignition, reliable and exactly defined ignition conditions which result in low emissions of noise and noxious substances are provided over the entire operating range of the engine.

Patent DE-3738248-A1 (DE)
Inventor: FISCHBACH GUNTHER DIPL ING
IPC: B29C45/77
Filed: 1987-11-11
Abstract: In the production of mouldings from crosslinking moulding materials, in particular by the injection-moulding process, reproducible filling of the mould is problematical. Overfilling, with the consequence of flash formation, or underfilling, with the consequence that rejects are produced, frequently take place. In the case of the method proposed, the degree of mould filling is controlled with the aid of the pressures measured in the mould. The method makes use of the fact that crosslinking moulding materials are generally introduced into a mould which is of a higher temperature than the moulding material. After filling the mould, the moulding material is heated up in order to start the crosslinking reactions. The heating up causes a volume expansion. If the mould is completely filled, the expansion is prevented and a pressure increase occurs. If the mould is underfilled, expansion completely or partially takes place. The pressure increase is then less or there is no pressure increase. With suitable boundary conditions, these pressure signals characterise the mould filling level. The method provides mould filling control which acts from shot to shot. The reference variable for the control loop is the mould cavity pressure. The correcting variable for the control is, in the case of injection moulding, the metering stroke. In the case of other processes, the metering weight or the metering volume may be used. <IMAGE>

Title: Vertical wind turbine
Inventor: BUTTLER ERNST
IPC: F03D3/06
Filed: 1988-01-21
Abstract: The known vertical wind turbines have the disadvantage that the turbine blades, belonging to the rotor, of the counter-rotating rotor half create a wind resistance for the descending current. In order to achieve a greater utilisation of the wind energy, it is proposed that the rotor have a fabric covering which, due to its density, is never overloaded despite high wind speed. Furthermore, the entire weight of the rotor is received by a multiplicity of friction wheels or movable elements which, at least in part, drive generators.

Abstract: A plurality of circumferentially displaced hollow members (28) are positioned between an outer bypass duct and the center body of the core engine of a gas turbine. Each of the hollow members is open at the radially outward end thereof for receiving relatively cool gas from the bypass duct. Each hollow member is formed with an opening (48) in the side thereof extending substantially the full length of the hollow member near the trailing edge thereof for discharging bypass gas (49) from the bypass duct in a direction facilitating thorough mixing of the bypass gas and core gases (38). A pivoted vane (50) may be provided in this opening of each of the hollow members and these vanes are controlled to vary the airflow through the aforementioned openings. Radially extending spraybars (44) or fuel rods are provided within each hollow member adjacent opposite sides thereof so as to be cooled by the bypass air flowing through the hollow member. The spraybars are provided with a plurality of openings adjacent the sidewalls of the hollow members and corresponding openings (46) are provided in these walls so that fuel, during augmentor operation, is directed into the area between adjacent hollow members. The aft end of each hollow member is formed as a relatively wide flat surface (36) which acts as a flameholder for the fuel supplied from the spraybars and burned in the augmentor. The forward end (40) of each hollow member is curved to an angle corresponding generally to the swirl angle of core gases exhausted from the core engine so as to effect a deswirling of this gas. <IMAGE>

Title: Puncher (perforator), in particular office puncher
Inventor: ZIEBARTH JUERGEN OTTO
IPC: B26F1/36
Filed: 1988-09-22
Abstract: The single-hole puncher, which can be used in particular as an office puncher, comprises a housing which is open on both sides and, together with other punchers of the same design and so-called paper-positioning aids, can be pushed onto a rail, and can, when the housing is appropriately designed, accommodate rails of differing profiles, in particular angular profiles. The cross-sectional design of the paper-positioning aids largely follows that of the rail profiles. A rail which has proved particularly advantageous is one with at least one angular cross part lying at the bottom and pointing forwards, which serves as an additional paper rest or paper guide and makes it possible for the paper-positioning aids to be of a more simple design. <IMAGE>
