Patent DE-3830326-A1 (DE)
Title: Device to control an economy, and method of operating such a device
Inventor: DETHLOFF JUERGEN
IPC: G06Q99/00
Filed: 1988-09-07
Abstract: A device to control an economy, and a method of operating this device, use company bookkeeping entry and accounting machines (BAM). An incentive module (AM) of each BAM contains indices, which represent a type of business establishment, of product and of transaction in combination. An incentive coefficient (AKO) is assigned to each index. AKO > 1 represents a favoured combination, AKO < 1 a disadvantaged one. Every transaction is subject to the true, i.e. market price. On a transaction, the amount is multiplied by an AKO which corresponds to the index of this transaction. A determined and stored difference between the multiplication result and the original amount represents a number of incentive units, which is positive or negative depending on whether the transaction was favoured or disadvantaged. When a certain positive value is reached, the incentive units can be used. Data which are stored in the module are accumulated centrally, to change the coefficients by reprogramming the AM, depending on success. <IMAGE>

Title: Process and device for the heat treatment of wastes
Inventor: BERGMANN HEINZ
IPC: C10B53/00
Filed: 1988-10-18
Abstract: A process for the heat treatment of wastes, such as paper, wood wastes, domestic refuse and kitchen refuse and the like, in which the wastes to be treated are treated in a rotary drum at a relatively high temperature, whereupon the exit gases thus forming and a part of the remaining wastes are passed to a further heat treatment, is to be developed in such a way that, although the exit gases forming are burned as far as possible, the remaining wastes are further treated only to the extent of organic constituents being passed to incineration, but the remaining constituents can be taken to re-use as unsorted raw materials in a collecting container. For this purpose, it is provided according to the invention that the wastes to be treated are subjected in the rotary drum to a heat treatment which is started and maintained by the hot exit gases released during this treatment, the exit gases devoid of oxygen being recycled to the rotary drum and being brought beforehand to their starting temperature in a separate device.

Title: Device for closing bottles
IPC: B67B3/02
Filed: 1989-03-16
Abstract: The invention relates to a device (1) for closing bottles (12), having a rotor (2) which moves the bottles (12) on a track in the form of part of a circle, having a flanging device (5), and having bottle grippers (3) which are connected to the rotor (2), make the bottles (12) rotate about their own axis (42) and bring the bottles (12) into, and out of, engagement with the flanging device (5).

Title: Process for producing moulded parts from plastic
Inventor: WEIGEL JUERGEN
IPC: B29C33/68
Filed: 1989-04-07
Abstract: The invention relates to a process for producing moulded parts of a sheet, dish, tube or container type from curable, in particular fibre-reinforced plastic, in which the plastic is introduced into a closed space, bounded at least by an extensible release film and a positive and/or negative mould and is distributed in the said space uniformly over the mould area by vacuum and/or pressure. In this process, to achieve the effect of compensating for still existing unevennesses, in particular dust on the surface of the mould, or that such unevennesses can no longer be seen on the surface of the moulded part and consequently that the moulded part has a very smooth surface, it is proposed that an extensible soft film is stretched over the surface of the positive and/or negative mould. <IMAGE>

Patent DE-3918926-A1 (DE)
Title: Constant pressure flow control valve - has tubular valve spool sliding over fixed sleeve with high pressure sealing surfaces of equal dia.
Inventor: BRUNNER RUDOLF
IPC: F15B13/04
Filed: 1989-06-09
Abstract: Good sealing surfaces are produced between the valve spool and the fixed part of the valve. Fitting into the stepped bore (2) of the valve housing is a fixed sleeve (14) which is sealed at each end (33). In the annular space between the sleeve and housing is the tubular spool (3) which slides over the sleeve and seals in the two regions (17) and (18) over a distance (L). The coil spring (7) loads the spool to the left with a force that is adjustable. Ports (6, 24) in the spool and sleeve overlap to create a shutter opening (B) which throttles and finally shuts off the supply of pressurised oil to the outlet passage (28) as the spool moves to the right. The movement of the spool and hence the amount of throttling is determined by the difference between the supply pressure forcing the spool to the right and the downstream pressure forcing the spool to the left. USE/ADVANTAGE - Free oil passage through the valve. Sealing surfaces can easily be produced. Well defined valve characteristic.

Title: Method and device for continuously measuring gas-borne alpha activity
Inventor: PETER JUERGEN
IPC: G01T7/04
Filed: 1989-06-14
Abstract: A method and a device are described for continuously measuring the gas-borne alpha activity which is produced by the decay of thorium, uranium, plutonium and their decay products (reaction products, descendants). For this purpose, the gas-borne alpha activity which results from the decay series of radon-220 and/or radon-222 is subtracted from the total gas-borne alpha activity. The former alpha activity is measured behind an absorber which transmits only the alpha rays of polonium-212 or polonium-212 and polonium-214.

Patent DE-3929029-A1 (DE)
Inventor: GADEMANN LOTHAR DIPL ING
IPC: H05B41/04
Filed: 1989-09-01
Abstract: The proposal is for a circuit arrangement for operating a gas discharge lamp (1) in which the high voltage to strike the gas discharge lamp is generated via the energy stored in a transformer (7) or capacitor. To ensure a steep rise in the ignition voltage, it is fed to the gas discharge lamp via a voltage-controlled switch (5). It is proposed that the voltage-controlled switch (5) takes the form of a tumbler diode which has very short switching times. The ignition circuit is switched off after ignition. This circuit arrangement is especially suitable for striking gas discharge lamps which are still warm from operation. It is therefore particularly suitable for motor vehicle headlamps.

Title: Symmetrical switch discharge system for inverter branch pair - uses gate controlled semiconductor switches connected to DC voltage source
Inventor: EGGERT BERNHARD DR ING
IPC: H02M7/519
Filed: 1990-06-23
Abstract: Two free wheeling diodes (D1, D2) are respectively in anti-parallel with a semiconductor switch (T1, T2) and a series circuit consisting of a common switch off discharge capacitor (CS), a switch off discharge diode (DS1, DS2) and a storage capacitor (CO1, CO2). A connection of each capacitor makes contact with one of the poles of the DC source (Ud) via an ohmic resistance (RO1, RO2). The choke coils are built as linear choke coils (LK1, LK2), limiting the current rise with the switching on of one of the semiconductor switches. The other connection (not lying at the AC terminal) of the switch off discharge capacitor is connected at the junction of the two storage capacitors, not connected to the ohmic resistance. One of connections of the ohmic resistances is connected directly with one of the poles of the DC voltage source (Ud), and the other connection is applied at the junction of the switch off discharge diode and the storage capacitor within the respective series circuit. USE/ADVANTAGE - Symmetrical switching discharge system for inverter branch pair formed from gate controlled semiconductor switches. Known circuit improved, so that switching discharge is possible at low cost without disadvantages of unsymmetrical commercial system.
