Patent DE-3611234-C1 (DE)
Title: Screening machine for the passage of broken rock, scrap, building rubble or recycling material
Inventor: BOEHRINGER PAUL
IPC: B07B1/46
Filed: 1986-04-04
Granted: 1987-10-08
Abstract: The invention relates to a machine for the passage of preferably mineral solids to be processed, such as gravel, scrap or building rubble, as well as recycling material, which is provided with hydraulic or pneumatic units as drives and in particular for the pivoting adjustment of the inclination of the working table during operation. This allows remote control, program control or control on the basis of monitored values to be used for adaptation of the working characteristics of the machine to the requirements resulting in each case and thus optimisation of the throughput and product quality without the machine being stopped (Figure 2). <IMAGE>
Patent DE-3613335-C1 (DE)
Title: Continuously operating centrifugal drum for concentrating solids in suspension
Inventor: BRUENING PAUL DIPL-ING
IPC: B04B11/02
Filed: 1986-04-19
Granted: 1987-08-06
Abstract: In the continuously operating centrifugal drum 1 for concentrating solids in suspension, the solids are directed from the solids space 5 to an inner chamber 8 via channels 3. Before the solids arrive in the inner chamber 8, they must pass through a ribless annular space 6. Since the solids concentrate attempts to increase its available kinetic energy, a large through-flow resistance is thus produced. With increasing viscosity, the solid in the ribless annular space 6 is, however, increasingly influenced by friction so that its kinetic energy is reduced and the through-flow resistance thus becomes smaller. With the increase which is brought about in this way in the drawn-off quantity of solids, its concentration and thus the viscosity is also reduced. By virtue of this behaviour of the solids in the ribless annular space 6 of a rotating centrifuge drum 1, automatic control of the solids concentration is achieved. <IMAGE>

Patent DE-3743195-C1 (DE)
Title: Taper-disc gear
Inventor: RATTUNDE MANFRED
IPC: F16H61/662
Filed: 1987-12-19
Granted: 1989-02-09
Abstract: What is specified is a taper-disc gear of continuously adjustable step-up, having a fully hydraulic generation of the pressure forces, in which the load-dependent setting of the pressure-force level takes place via a torque sensor which is seated on one of the gear shafts and via which the power to be transmitted by the gear is introduced into the gear and which forms for the pressure medium a throttle adjustable in a torque-dependent manner. At the same time, the torque sensor is designed so that, when torque surges occur, it can briefly introduce into the circuit a predetermined volume of pressure medium. The torque sensor is followed in the hydraulic circuit by a pressurising valve for the additional throttling of the pressure-medium flow in dependence on the step-up setting of the gear, in such a way that, altogether, a setting component dependent on torque and a setting component dependent on the step-up are added to the pressure level to be set for generating the pressure force.

Title: Setting device for setting the belt tension of the driving belt of a motor vehicle
IPC: F02B67/06
Filed: 1989-02-21
Granted: 1990-01-04
Abstract: An illustration and description are given of a setting device (1) for setting the belt tension of the driving belt of a motor vehicle, having a tension force application element (2) and a tensioning element (4) cooperating with a tensioning counter-element (3). Since, in the case of the setting device (1) according to the invention, a tension-force limitation (6) is realised between the tension force application element (2) and the tensioning element (4), it is achieved that the correct belt tension is always set without special aids, in particular without torque wrenches or the like. <IMAGE>

Filed: 1993-11-25
Granted: 1995-03-09
Abstract: Using a device for making contact with the electrodes of high-temperature fuel cells, in particular for interposition between the electrodes and the bipolar plates or separating plates, it is intended to create a solution by means of which, on the one hand, optimal electrical contact is achieved with the electrodes while, on the other hand, a less exact surface quality, for example of the anodes and cathodes, can be accepted at the same time without this leading to disadvantages in making contact.

Title: Parcel distribution system
Inventor: BOCKHOEFER HARTMUT
IPC: B07C3/02
Filed: 1994-04-08
Granted: 1995-06-14
Abstract: The invention concerns a method of distributing parcels or other piece goods for delivery to addresses scattered throughout a supra-regional distribution system. The parcels are assembled at at least one depot and forwarded to distribution points from where they are delivered to the addressee by vehicle delivery rounds. In order to make the method more cost-effective and more rapid, the invention calls for the parcels to be grouped in delivery-round assemblies when they are taken to the depot, placed in a particular order corresponding to the course of a delivery round and brought in this order to the distribution points and placed in the vehicles. The container for carrying out the method is designed as a vehicle unit load with at least one closable access opening and preferably with internal shelves enabling parcels to be positioned in the correct order.
