Patent DE-3907330-A1 (DE)
Title: Separation process
Inventor: LAUTENSCHLAGER GERT DR
IPC: B01D53/56
Filed: 1989-03-04
Abstract: The optimal working range of a non-catalytic separation method is often restricted to a defined temperature range. This applies, in particular, to non-catalytic denitration methods. To adapt the separation process to great temperature variations, a solution containing the substance to be separated off is used in a support substance. Since the separation between the substance to be separated off and the support substance requires a certain time, the timepoint of the start of the reaction between the substance to be separated off and the substance separating off can be controlled and, when the medium containing the substance to be separated off moves, the site of the start of reaction can also be controlled.
Patent DE-3907741-A1 (DE)
Title: Accumulator (rechargeable battery)
Inventor: SCHOELL GUENTER PROF DR ING
IPC: H01M10/04
Filed: 1989-03-10
Abstract: In the battery, which is constructed from a large number of individual cells arranged in series, the walls of the cells consist of electrically conductive plastic and are used as a load-bearing element for the active compounds which are involved, on their own, in the electrochemical process, as well as for the electrical power supply and the electrical power output. These active compounds are deposited in numerous, very small, partially closed channels or honeycombs which are located in the surfaces of the cell walls. With insulating sealing rings being interposed, the cell walls, which are arranged in series, are held together by two end plates, by means of tie rods, and individual cells are thus formed which accommodate the electrolyte in them.

Title: Process for the production of scalded unsmoked sausage, sausage meat dumplings and similar products
Inventor: KORTSCHACK FRITZ
IPC: B65B25/06
Filed: 1989-04-06
Abstract: The invention provides charging uncooked sausage meat into preformed (deep-drawn) films via a vacuum packaging machine with the aid of a distributor head. After filling, the packages, in which are situated a plurality of raw products, e.g. frying sausages, adjacent to each other without touching, are covered with a further film (covering film) and evacuated. Afterwards both films are welded together (surface welding). The package containing the fresh sausage meat is heated. The contents are thus preserved. Since the individual finished products are already air-tightly packaged by the process, the risk of microbial contamination is excluded. All aroma substances remain in the product. The highly labour-intensive filling and packaging process is automated. Moreover, the use of natural casings or other casings is dispensed with.

Patent DE-3922040-A1 (DE)
Inventor: STEHLE K-HEINZ DIPL ING
IPC: F16H61/02
Filed: 1989-07-05
Abstract: In order to improve the shifting characteristics of an electrohydraulically controlled, automatically shifting transmission particularly during cornering and braking, the driving speed (v), the lateral acceleration (aq), and the time variation of the throttle valve position are sensed in addition to the throttle valve position (alpha) and the engine rotational speed (nmot). From the time variation of the throttle valve position, a signal can be derived for the prevention of an upshifting operation since a motor vehicle driver's foot moves away faster from the accelerator pedal when approaching a bend in the road than would be the case for the normal deceleration of the motor vehicle.

Abstract: The palletizer includes a vertical column 16, a telescoping horizontal arm 18 mounted for vertical movement along the column and a hand assembly 20, comprising gripper plates 38, 40, mounted at the end of the horizontal arm. A pair of photodetectors 62, 64, movable with the hand assembly, sense the presence and location of cartons 68 in place on a pallet 14 being loaded and signal the palletizer when the vertical height and horizontal extension of the hand assembly are sufficient to place cartons in the proper position for loading onto the pallet. A circuit controls operation of the palletizer in accordance with the sizes and shapes of the cartons and pallets and permits limited variation of the loading pattern provided by the palletizer. Separate conveyors transport cartons to the palletizer for loading (conveyor 52, 54) and remove loaded pallets from the palletizer upon completion of the loading cycle (conveyor 48). <IMAGE>
