Patent DE-2940016-A1 (DE)
Title: Transformer station with separate LV and HV parts - has multilayer assembly for heat convection transfer to HV part
Inventor: FABRICIUS UFFE
IPC: H02B7/06
Filed: 1979-10-03
Abstract: The heat radiation control and permeability assembly in a transformer station provides the convection of a heat portion, which has been generated as lossy heat in the transformer(1), to the high voltage chamber(2) which forms a space separate from the transformer station low voltage part. The heat convection system has preferably one or several layers of radiation absorbing material(3) in the wall of the high voltage chamber. Preferably the layer(s) is mounted on the side of a heat conductive partition between the high voltage chamber and the transformer cubicle, and consists of a thermally black material. For the heat radiation control may be used radiation reflecting members(4) in the transformer station in such configuration as to reflect the heat radiation against the high voltage chamber. The heat transfer to this chamber is intended for moisture reduction due to condensation.

Title: De-stoning instrument for cherries and other fruit - has levers connected to stoning rams movable into useful and rest positions
Inventor: KURTZ THEOBALD
IPC: A47J23/00
Filed: 1979-12-12
Abstract: The de-stoning rams (30,31) are driven by a ram-rod (13) which moves against the force of a resetting spring inside the frame. They are fixed to levers (25,26) which can be brought into and out of engagement with coupling elements (34,35,36) which are located on the rod (13) and can be rotated with the same (13) about their longitudinal axis (37). There is now a distinct position of use and position of non-use wherein when the destoning ram is uncoupled from the ram-rod the cutting tools and their sharo edges drop down under gravity into the troughs which surround the sharp edges like a protective grid to prevent injury.

Title: Drum type clothes dryer - with air circulation through two counter flow heat exchangers for condensation and heating
Inventor: MUELLER FRANZ
IPC: D06F58/20
Filed: 1980-03-14
Abstract: A drum clothes dryer uses a circulating air flow in which a coolant extracts the moisture from the air leaving the drum in a first heat exchanger and a second heat exchanger heats up the dry air. The coolant is sprayed into the air for a pre-condensation and the mixture passes through the first heat exchanger in counterflow to the incoming coolant. After the air has been cooled below the dew point, the second counterflow cooler heats up the air by the discharged coolant. This recovers the maximum of heat energy and shortens the drying time.

Title: Word processor display control unit - uses incrementing display with buffer store and facility for error correction
Inventor: SCHLEGEL UDO ING GRAD
IPC: B41J3/46
Filed: 1980-03-19
Abstract: A word processing system provides an improved facility for correction of text errors. The system utilises an alphanumeric keyboard together with a function keyboard, e.g. erase, print, etc. A microcomputer system controls the operation of the word processor and uses a programme memory, data memory and a microprocessor. Output from the unit in response to entered characters is transferred to a buffer memory and a display that increments from right to left with capacity for 15 characters. If an error in data entry is made, the erase key is operated. This may include either single or multiple character corrections. Data are erased from the display store and new data entered. Output is finally transferred to the printer.

Title: High pressure hydrogen purification by condensation - in conjunction with purification of medium pressure stream with heat interchange
Inventor: BECKER HANS DIPL ING DR
IPC: F25J3/06
Filed: 1980-07-29
Abstract: A method of purifying a high-pressure hydrogen stream at pressure above 100 bar by cooling in multi-stage partial condensation with sepn. of the condensate at each stage and indirect heating of the condensates and the uncondensed, purified high-pressure hydrogen stream is carried out in conjunction with a flow of medium pressure hydrogen as follows. In parallel with the high-pressure hydrogen stream a medium-pressure stream (pref. at 20-80 bar) of hydrogen and higher boiling components is similarly purified by multi-stage partial condensation, sepn. of condensate and heating of sepd. condensate and non-condensed hydrogen. The high-pressure hydrogen stream is cooled in an indirect heat exchanger by giving up heat to the medium-pressure stream; this is followed by an opt. further, similar cooling stage for the uncondensed hydrogen, until finally in a separator the hydrogen is purified, virtually all the hydrocarbons being removed as condensate. The uncondensed stream, typically comprising 94.4% hydrogen and 3% methane and 2.6% argon, nitrogen or CO, now passes to a series of heat exchangers where it is heated up by thermal exchange with the medium-pressure stream. In particular for use in the Linde high-pressure hydrogenation process or high-pressure synthesis process. The heat exchangers reliably operate and are simple in construction.

Patent DE-3045715-A1 (DE)
Title: Remote power switching circuit for TV or radio - has rechargeable power source for initial relay operation in transistor control circuit
Inventor: WAHL PETER
IPC: H04B1/16
Filed: 1980-12-04
Abstract: The power is switched using relay contacts in the mains supply circuit to the equipments power supply circuitry (5). The circuit does not rely upon a stand-by mains power feed to operate the remote control switching. Whilst the equipment is in operation one output feed (U1) from the power circuit (5) is used to recharge a battery (8). Transmitting an 'ON' signal from the remote control (9) causes the receiver (6), powered by the battery (8) to feed a "turn-on" voltage via a potential divider circuit (11,12) to a switching transistor (13). This allows current to flow in the relay coil (4) to operate the mains contacts (3). A relay (4) holding current is obtained from the power supply (5). Operating the manual switch (1) with its ganged contact (2) also passes a turn on voltage through to the switching transistor (13) to operate the holding relay (4). Turning off is accomplished by turning off and blocking the controlling transistor (13).

Title: Shredder for waste paper - has shredding chamber edge between vertical line though rotor centre and vertical line tangential to cutter pitch circle
Inventor: PROBST KARL
IPC: B02C18/00
Filed: 1980-12-06
Abstract: The waste paper shredder has a rotor operating inside a ring-shaped shredding chamber into which the material is fed through a hopper (6) with an inclined chute (20) terminating in a shredding chamber edge (21). The edge formed by the circular wall (10) of the shredding chamber and the inclined chute (20), is on one side of the shredding chamber inlet opening (35). The edge is positioned between a vertical line (23) passing through the rotor centre and a vertical line (24) passing tangentially to the pitch circle (22) on which the shredding tool tips (4) moves. The straight line connecting the shredding chamber edge with the rotor axis (2) encloses an angle (18) with the horizontal (19), which varies between 30 and 50 degrees.
Patent DE-3102757-A1 (DE)
Title: Rubber tyre with interchangeable tread rings
Inventor: SCHMALZ REINHOLD
IPC: B60C11/02
Filed: 1981-01-28
Abstract: When manufacturing the tyre carcass, wedge-shaped radial grooves with control curves are pressed into the tyre tread. A sliding band (permanently magnetic if required) and an anti-skid tread ring are inserted into each groove, a controlled sliding and fixing of the spikes which are located in the interchangeable anti-skid tread ring being possible as a result of this (Fig. 3). As a result of the different slip on roads covered with ice and snow, the anti-skid tread ring, equipped with spikes, in the tyre groove, turns automatically radially in relation to the tyre tread, as a result of which the spikes are pressed approximately 1.5 mm out of the anti-skid tread ring and grip tight into ice and snow. On dry roads, the spikes are automatically lowered in the anti-skid tread ring since synchronisation with the anti-skid tread ring occurs as a result of the larger tyre tread area. During the summertime, the anti-skid tread rings can be removed from the radial grooves of the tyre tread area and reused. With a profile depth of less than 4 mm, an anti-skid tread ring should no longer be used; the tyre can however be used up to the wear limit in summer conditions. Instead of tread rings, the radial groove can also hold chain-like anti-skid devices. <IMAGE>
