Title: Process for producing chipboards, fibreboards or similar boards
IPC: B27N3/18
Filed: 1981-02-27
Abstract: A process for producing chipboards, fibreboards or similar boards is described in which, for the purposes of an improved density distribution across the entire cross-section and to minimise the edge losses, before a substantial compression is carried out, the non-woven fabric is introduced without an air gap between the heating electrodes and the actual compression operation is only carried out when the non-woven fabric has been heated to a temperature of at least 40 DEG C by means of the high-frequency energy.

Title: Piston/cylinder unit
Inventor: LEHLE ROBERT DIPL ING
IPC: F15B11/12
Filed: 1981-03-02
Abstract: The invention relates to a piston/cylinder unit for actuating and setting the chokes of buses in three different positions. It consists of a cylinder with a piston whose two end faces can be acted upon by a pressure medium. Slipped onto the piston is an annular auxiliary piston which is displaceable on the piston and relative to the latter axially by a predetermined distance. One end face of the auxiliary piston can be acted upon by the pressure medium, while its other end face can be struck against a shoulder on the inner wall of the cylinder. In this way, it is possible to move the piston in a controlled manner into two end positions as well as into a centre position.

Patent DE-3116315-A1 (DE)
Inventor: CONZELMANN GERHARD DIPL PHYS
IPC: H02J7/16
Filed: 1981-04-24
Abstract: Generator system comprising a self energization generator (1), a voltage regulator (3), a transfer device (4) for taking in charge the current which continues to circulate during the disconnection of the energization coil (2) and a reception device (9) for absorbing the reaction energy during the switch off of a load (11) of the generator. The transfer device (4) acts as the conventional diode (13) of free passage; it has a current path with a low passage threshold voltage switchable to a high threshold voltage. During normal operation of the generator (1), the energization coil (2) is connected on the path with the low passage threshold voltage. When the load (11) is separated from the generator, the energization coil (2) is connected to the pass with the high breaking voltage. The energization current decreases rapidly. Thus, the reaction energy which must reinforce the edge network protection (9) is strongly decreased.

Title: Piston pump for liquified gases
Inventor: TURNWALD ERNST ING
IPC: F04B15/08
Filed: 1981-12-16
Abstract: A piston pump for liquified gases has a piston capable of performing a reciprocating movement in a cylinder, which piston forms a suction chamber and a working chamber. A suction line closable by means of a non-return valve is assigned to the suction chamber, whilst a pressure line closable by means of a pressure valve is assigned to the working chamber. The piston has a bore on which a valve seat is arranged on the suction chamber side. A disc valve, the shaft of which is passed through the bore of the piston and is connected to a drive rod for the piston, which is assigned to a drive device, acts in concert with the valve seat. On the piston a stop is formed which, when the drive rod moves in the direction of the suction chamber and after the valve disc has lifted off from the valve seat, transmits the movement of the drive rod to the piston.
Patent DE-3150439-A1 (DE)
Title: Digital generator of call progress tones for telephone branch exchanges
Inventor: ROBRA JOERG DR
IPC: H04Q1/448
Filed: 1981-12-19
Abstract: For generating call progress tones in digital telephone switching systems, memories are used for coded samples of these call progress tones. The stored samples are inserted instead of voice signals into a time slot by means of a control circuit. During this process, a great effort is involved when the call progress tones are required at the same time as voice signals. In addition, it is not possible to transmit other low-frequency signal voltages such as call and charge metering pulses in the same manner. In the digital generator of call progress tones according to the invention, a read-only memory is used as memory. The addresses of memory areas of this read-only memory are determined by a counter in dependence on the clock pulses from a crystal oscillator. To generate analog signalling and call progress tones, the storage areas of the read-only memory read out are supplied to one digital/analog converter for each frequency and to a filter circuit. If the samples are coded in accordance with the delta modulation method, the digital/analog converter can be omitted.

Title: Process for desorbing organic gases adsorbed on adsorbents from a carrier gas
Inventor: RICHTER EKKEHARD DR ING
IPC: B01D53/04
Filed: 1982-01-14
Abstract: In a process for desorbing organic gases adsorbed on adsorbents from a carrier gas, by flushing the adsorbent within a reactor with a gas (flushing gas), which is partially adsorbed in the process, a reduction of the energy expenditure in an environmentally safe manner and recovery of the organic gas are achieved by using as the flushing gas a carbon oxide or hydrocarbon having one carbon atom per molecule at a pressure (desorption pressure) below the pressure prevailing during the adsorption; in the process, the flushing gas can be displaced by the carrier gas in another adsorption step, and in the desorption step can be freed of desorbed organic gas at a pressure higher than the desorption pressure and be reused for desorption. <IMAGE>

IPC: E06B7/10
Filed: 1982-08-14
Abstract: In an apparatus for room ventilation which consists of two separate air ducts which are mutually in heat exchange contact through heat exchange surfaces, one air duct serving to carry away exhaust air to the outside and the second air duct serving to feed fresh air in and at least one fan being associated with each duct, it is to be ensured that neither the fresh air fed into the room reaches the exhaust air suction channel provided there, nor, vice versa, the exhaust air conducted to the outside can be sucked in by the fresh air channel provided there.

Title: Process for lowering the platform of an artificial island onto a substructure and apparatus for carrying out the process
IPC: E02B17/02
Filed: 1982-09-15
Abstract: When lowering the platform, carried by floats, for example pontoons, its oscillating vertical motion, following the swell of the sea, is blocked at a low point; the resulting forces are transferred to carrying devices, which are connected to the platform and to the substructure. By ballasting the floats and at the same time adjusting the carrying devices, the platform is then lowered further and finally, while continuing lowering, is set down onto the substructure by means of the carrying devices against the buoyancy of the floats. In this way, the free motion of the platform at the beginning of the setting-down operation is transferred over a time span of a damped motion controllably, since pre-stressed against the water pressure, to the calm after setting down, without acceleration forces occurring. Vertically running tension members (22) and cylinder-piston units (18) arranged parallel to the said members are provided as carrying devices. The tension members (22) are anchored at their upper ends to the platform (1) and are supported at their lower ends against the substructure (6), with the cylinder-piston units (18) interposed. <IMAGE>

Title: Entertainment electronics equipment set of different equipment modules
Inventor: FREIBURGER EWALD
IPC: H04B1/20
Filed: 1983-01-29
Abstract: An entertainment electronics equipment set composed of different audio equipment modules (6, 7) is supplemented by video equipment modules (1, 4, 5). The individual equipment modules are electrically connected to one another via buslines (10, 11, 12, 13, 19) of a bus system (9). So that the limited number of buslines is not increased, control voltages of a different voltage level, to which voltages the video signals are clamped, are additionally transmitted via the video signal busline (13). The video signals are separated from the control voltages in a monitor equipment module (5) and the control voltages are decoded at threshold switches (42, 43). In this manner, all control and video signals are transmitted by only one busline to which an arbitrary number of video equipment modules can be connected. <IMAGE>
