Patent DE-3809647-A1 (DE)
Title: Device for filling small tubular electrodes for lead-acid accumulators
Inventor: MITTERMAIER XAVER DIPL ING
IPC: H01M4/16
Filed: 1988-03-22
Abstract: In the case of a device for filling small tubular electrodes for lead-acid accumulators, a pressure tube (1) which is filled with pasty, active compound has outlet openings (2) along an envelope line. The number of these outlet openings (2) corresponds to the number of small mesh tubes (3) to be filled, and the pressure tube is surrounded by a rotating ring (8) having at least one pair of opposite bearing bars (6, 6'), each having a set of projecting filling tubes (5, 5'). The rotating ring can be rotated with the filling tubes from a plugged-on position (A) into a filling position (F) in which the filling tubes (5) can be connected to the outlet openings (2) in order to allow the compound to overflow out of the pressure tube (1), while, in the plugged-on position, the opposite filling tubes (5') are available for the small mesh tubes (3') to be plugged on at the same time. If the rotating ring (8) which supports the bearing bars (6, 6') has a larger diameter than the pressure tube (1) and is supported eccentrically with respect to the pressure tube, the filling tubes can be guided such that they are particularly tightly sealed against the outlet openings of the pressure tube. <IMAGE>

Title: Plough system for underground winning operations
Inventor: BECKER KUNIBERT
IPC: E21D23/00
Filed: 1988-04-20
Abstract: In the plough system according to the invention, the plough guide (6) arranged in front of the working face (1) is mounted, preferably in a vertically pivotable manner in joints (42), on distance pieces (37) preferably consisting of foot rails (38) or the like which make the connection to the face conveyor (5).

Title: Lever bearings for a load-dependent brake pressure control device
Inventor: HARTMANN WILLI
IPC: B60T8/18
Filed: 1988-04-28
Abstract: In load-dependent brake pressure control devices the force proportional to the axle load is applied by way of a pivotably mounted lever to the piston of the control device in a controlling fashion. In the controlling state the control lever, driven by the control piston, performs a swivel movement about the pivot bearing of the lever with considerable frequency. The object of the invention is to improve the response and the function of the brake pressure control device. The invention in principle achieves the stated object in that a knife-edge bearing of the lever is provided in the housing. By means of this especially low-friction bearing, the friction of the lever during the swivel movement is considerably reduced, as a result of which the response, the sensitivity and the function of the brake pressure control device are improved. Advantageous developments of the invention are revealed in the dependent claims. <IMAGE>

Patent DE-3839809-A1 (DE)
Title: Liquid reservoir for motor vehicles
Inventor: MAERTZ JOSEF
IPC: B60S1/50
Filed: 1988-11-25
Abstract: Known liquid reservoirs are made of dimensionally stable material, the shaping of which requires particular tools. Furthermore, these liquid reservoirs cannot readily be inserted into the often small openings in the vehicle-body cavities. The intention of the novel liquid reservoir is to avoid these disadvantages. This aim is achieved by virtue of the fact that the liquid reservoir (10) comprises a flexible film container (11) and a dimensionally stable, plate-shaped part (15) connected in a sealing manner thereto.   The liquid reservoir (10) can be inserted into virtually any cavity in the vehicle body (1) and can correspondingly contribute to an improved distribution of weight. <IMAGE>
Patent DE-3839967-A1 (DE)
Title: Torque force converter
Inventor: MAYER HELMUT DIPL ING
IPC: F04D3/00
Filed: 1988-11-26
Abstract: The invention relates to a torque force converter in which propeller torques are converted in an energy saving fashion into flow forces (jet thrust (propulsion) and wing lift forces). The design is to be used principally as a hydrodynamic drive and in the building of pumps and test conduits. The ratio of FORCE/propulsion POWER = F/P is substantially more favourable in accordance with the invention than in the case of previous designs. This is achieved by means of two hose tubes (3 and 4, FIG. 1), in which identical, but oppositely rotating water flows 1.1 and 1.2 are generated by means of two equal and opposite, contrarotating propellers whose rotary and translatory kinetic energy is entirely converted into translational energy 1.3. The energy of fluid rotation is entirely converted into translation. The total translation 1.3 is distributed in a uniformly elliptical fashion over the exit cross-section O'-O', and can be used as high jet power in the case of an ideal jet shape. The jet can flow on to aerofoils in open pipes or closed ring mains (headers). The lifting forces thereof are used for positioning and manoeuvring. <IMAGE>

Title: Shoe with watertight connection between shaft and outsole and method of manufacturing this connection
IPC: A43B7/12
Filed: 1988-11-30
Abstract: A shoe, the shaft (1) of which consists at least of one outer shaft material and a watertight but water-vapour-permeable diaphragm arranged on the inner side thereof. For watertight connection of the shaft (1) to the outsole (2, 3), a sealing band (4), which at its lower edge is sewn together with the diaphragm and the insole (5) of the shoe, is sewn onto the lower edge (14) of the outer shaft material. The sealing band (4) is coated with a plastic which belongs to the same type as the plastic of the diaphragm and the outsole (2, 3) and can consequently be welded together with both under the effect of heat and pressure. As a result, the sealing band (4) can first be sealed together in a watertight manner with the diaphragm; subsequently, a watertight connection is made by extrusion coating the outer side of the sealing band (4) with the plastic of the outsole (2, 3) (Fig. 1). <IMAGE>

Title: Severing cabbage stalks and blowing off leaves - while heads are mounted in continuous conveyor
Inventor: GEERKENS HARTWIG
IPC: A23N15/00
Filed: 1989-07-04
Abstract: Freshly harvested cabbages are prepared for selling and/or processing into salads by cutting off the stalk and the outer coarse covering leaves.  While mounted in a rectilinear or rotary conveyor whose holders, designed for different possible cabbage sizes, hold the cabbage in upright position without lateral or vertical shifts, the stalk is cut by a moving blade. The outer leaves are then sepd. by an air jet directed from a nozzle whose mounting on the blade support ensures the sepg. air stream is correctly directed. The air stream is insufficiently strong to damage or dent the stripped head, and its directionality ensures no unnecessary power loss. A number of stripping stations may operate simultaneously. ADVANTAGE - Output is high and risk of injury to operators, esp. from cutters, is minimised.
