Patent DE-3107231-A1 (DE)
Title: Positive-displacement machine for compressible media
Inventor: MUELLER CLAUS
IPC: F01C17/06
Filed: 1981-02-26
Abstract: The invention relates to a positive-displacement machine for compressible media having at least one impeller chamber (displacer chamber), which is arranged in a fixed casing and is constructed in the manner of a spiral slot, and, assigned to each impeller chamber, a displacer body which is likewise of spiral shape and is retained on an eccentrically drivable, disc-shaped rotor. The eccentric drive in this arrangement is to be effected in such a way that, during operation, each of the points of the displacer body carries out a circular movement delimited by the perimeter walls of the impeller chamber, and that the displacer body nearly touches the inner and outer perimeter walls of the impeller chamber at, in each case, at least one sealing line which moves on continuously during operation. In order to achieve as simple a design as possible for the eccentric drive of the rotor and at the same time ensure satisfactory guidance of the rotor, the invention provides for two eccentric arrangements (4-6 and 7-9) to be arranged at a distance from one another, of which one can be driven via a drive shaft (5). In order to ensure unambiguous guidance even in the dead-centre positions of the rotor, the two eccentric arrangements may either be linked, in a constrained manner, via a toothed-belt drive (12-14), or a spring arrangement is provided which, during at least part of the rotor motion, is tensioned for the purpose of subsequent displacement of the rotor beyond the dead-centre points. <IMAGE>

Title: Process and apparatus for preparing potable alcohol
Inventor: TEBBENHOFF EBERHARD DR
IPC: C12H6/02
Filed: 1981-04-02
Abstract: Process and apparatuses for preparing potable alcohol containing raw-ingredient-specific flavour components from fermented mashes, in which crude spirit is isolated from the respective mash by distillation which is subjected to a preliminary purification and then a rectification to isolate the potable alcohol, have been operated hitherto in two stages. This was due to the crude distillation apparatus designed for continuous operation and, in contrast, to the rectification installation constructed for discontinuous operation. In order to reduce running time losses and in particular heat losses in such installations, the crude spirit is now pre-purified in vapour form by extraction as crude spirit alcohol and then passed in vapour form to the rectification. The purification apparatus is therefore composed of a continuous extraction apparatus to which the crude spirit is passed as a vaporous crude spirit alcohol directly from the crude distillation apparatus and from which the pre-purified vaporous crude spirit alcohol is passed on to the rectification column. The rectification column in this case is continuously operated just as is the crude distillation apparatus. Intermediate cooling of the crude spirit alcohol before the rectification is dispensed with.

Patent DE-3123886-A1 (DE)
Title: Process and apparatus for the guidance of air on a mangle
Inventor: STICHNOTH OTTO
IPC: D06F67/00
Filed: 1981-06-16
Abstract: In a process for the guidance of air on a mangle, the rollers of which are indirectly heated from outside by steam, fuel oil or the like, the air mixed with steam from the laundry is sucked off from the rollers (1 to 5). This hot air laden with moisture has hitherto passed into the atmosphere, with the result that its energy content is wasted. For a more expedient utilisation of the energy on the one hand and of the water absorbency of the air on the other hand, the air mixed with steam from the laundry is sucked off individually or in groups from the rollers (5 to 1) and fed respectively from outside again, in the upper region, to the roller or roller group preceding in the direction of flow (7) of the laundry, so that this air can absorb more moisture. The air sucked off from the roller (1) which is the first in the direction of flow (7) of the laundry is delivered again at least partially to the last roller (5) as circulating air. Between every two adjacent rollers (5, 4 or 4, 3 etc.), individual conduits (23 or 24, etc.) are provided, so that the air is moved in countercurrent with the direction of flow (7) of the laundry. <IMAGE>

Filed: 1981-07-15
Abstract: The invention concerns a ski particularly a touring and/or cross-country ski, with a binding (10) for holding an anterior tongue-shaped extension of the sole of a ski shoe. The binding (10) is formed by a recess (16) provided in the ski body (12) extending in the longitudinal direction of the ski, with a sole latching apparatus (abutments 18, 18'; latching device 20 or locking device 20') for fixing the sole extension and thus the ski shoe in a positively locked and friction-locked manner. The ski binding (10) is thus provided in the ski body (12) in integrated manner, so that no parts protrude above the ski deck area (14). In this way a subsequent mounting of the ski binding (10) is no longer necessary. In addition, the skis can be shipped with the ski binding (10) mounted for conventional skis without binding, tightly packed against each other. Finally, there is no additional friction caused by the ski binding during the cross-country run in somewhat deeper snow.
Patent DE-3132149-A1 (DE)
Title: Energy/insulating roof with pipe elements
Inventor: HAAG ERNST DIPL KFM DR
IPC: F24J2/00
Filed: 1981-08-14
Abstract: Roof comprising pipe elements which can be combined, consisting of plastic which can, for the most part, be extruded. The roof fulfils two functions, that is to say insulation with respect to the escape of heat radiation and/or the ingress of heat radiation. When a heat-conveying medium flows through the pipe system, a solar roof heated by the environment is formed; once the heat-conveying medium has been pumped away, the insulating function dominates.

Patent DE-3148164-A1 (DE)
Title: Thermal insulator
Inventor: YAMAMOTO RYOICHI
IPC: B32B5/16
Filed: 1981-12-05
Abstract: A thermal insulator comprises a foamed plastic body with at least one insulation zone, embedded therein, of evacuated insulating powder and a container surrounding the former and consisting of a plastic sheet or a sheet-like plastic/metal combination. The plastic body is advantageously foamed by means of a fluorochloromethane gas (Freon gas), since this has a larger molecule diameter as compared with air and thus less easily penetrates the wall of the container. Even without using a container having rigid and resistant walls, the thermal insulator therefore has the advantages of vacuum insulation.

Title: Radar device, from which digitally coded pulses are emitted
Inventor: MILANCH JOHN MAURICE
IPC: G01S13/28
Filed: 1982-04-23
Abstract: The radio device emits relatively long pulses, which are in each case modulated according to a certain code with a first or a second phase value. On the reception side, a pulse compression takes place in the evaluation. The known technique, in which tuned filters are used, is modified in such a way that a plurality of signal processing channels (318, 319, 320; 315, 316; 321, 322, 323) are provided for the pulse compression. If three channels are provided, in one channel (315, 316) a pulse compression takes place in a known way by means of tuned filters. In the two other signal processing channels, signals are processed with great positive or negative Doppler shifts. The sharply delimited complex video signal (301, 302, 303) generated in the receiver is fed to two shift registers (305, 306), which are respectively assigned to the first part and to the remaining part of the received code. In the signal processing channels for positive and negative Doppler shifts, complex multiplications (318, 321) are carried out, to be precise with a calculated phase rotation factor, which is optimised for a particular positive or negative Doppler shift. Instead of the three signal processing channels mentioned, it is also possible for more signal processing channels to be provided. In addition, it is possible to divide the received code into more than two part-codes. <IMAGE>
