Patent DE-3319318-A1 (DE)
Title: Heat pump
Inventor: OFFENBECK HERBERT
IPC: F25B1/10
Filed: 1983-05-27
Abstract: In a heat pump (1), the refrigerant circuit of which has a compressor (2), a condenser (3), an expansion device (4) and an evaporator (5), the refrigerant circuit after the evaporator (5) is first passed through the heat uptake portion (6a) of an additional heat exchanger (6). Between predetermined limits of the pressure or of the temperature of the refrigerant, the refrigerant circuit then runs through a non-return valve (7) before the entry into the compressor (2). To widen the limits of use of the heat pump (1), a supercharging fan (8) with a motor (11) is arranged in parallel with the non-return valve (7) and can be switched on by a constant pressure unit (9) and/or a thermostat (10). <IMAGE>

Title: Pressing machine, laundry mangle or the like having a pressing body designed as a hollow body and closed on all sides
Inventor: OBERT PETER PROF DIPL ING
IPC: D06F34/26
Filed: 1983-07-06
Abstract: To achieve a satisfactory pressing result, it is necessary for the temperature of the pressing body to be constant over its entire pressing surface. The pressing machine according to the invention is equipped, on the inside of the pressing body, with one or more electrically heatable high-temperature radiators. The heat emission takes place uniformly in the radial direction, so that the pressing body is heated uniformly. If the pressing body is designed in the form of a cylinder, the high-temperature radiator is arranged in the longitudinal mid-axis of the pressing body. Since the heat requirement is greater on the run-in side or in the run-in region for the pressing material because of the moisture content, the high-temperature radiator can also be arranged parallel to the longitudinal mid-axis of the pressing body and offset towards the run-in side. Where pressing bodies of non-circular cross-section are concerned, a plurality of high-temperature radiators can be used according to the cross-sectional shape. To regulate the temperature, there is a regulating device equipped with a temperature sensor. <IMAGE>

Patent DE-3329970-A1 (DE)
Title: Exhaust supercharger
Inventor: HARTMANN CHRISTOF
IPC: F02B37/00
Filed: 1983-08-19
Abstract: An exhaust supercharger for compressing the charging air of internal combustion engines by means of the energy of the exhaust gases has a two-bladed or double flap, the one blade of which is incorporated in the exhaust pipe and the other blade of which, the so-called compressor blade, is arranged in a sector-shaped chamber and defines at least one working chamber of variable volume, which as the volume of the cold or compressor chamber is reduced can be connected to the inlet port of the internal combustion engine and as the volume is increased, to the atmosphere. The compression and delivery cycle of the working chamber occurs due to swivelling of the flap as a result of the exhaust thrust of the exhaust gases flowing through the exhaust pipe and acting on the flap of the hot or expansion part. The induction cycle is brought about by the opposite swivelling of the flap as a result of the suction wave from the outlet valve following the pressure wave. In addition a recovery spring can also be provided. An exhaust supercharger hot or expansion part is connected downstream of each outlet of each cylinder of the internal combustion engine close to the outlet valve in order to keep the oscillation frequency of the flap low and in order to incorporate at least the hot part of the exhaust supercharger into the engine exhaust outlet or into the exhaust manifold.

Patent DE-3339866-A1 (DE)
Title: Increase in the complex efficiency of vehicles
IPC: F02B61/04
Filed: 1983-11-04
Abstract: With a hybrid drive arrangement comprising combustion engine, fan, heat exchanger and boundary layer blow-out device some of the waste heat energy, 2/3 of which has hitherto been lost, is converted into pressurised gas energy, which in the boundary layer control device serves for the reduction of aerodynamic resistance and in aircraft also for increasing the lift. The assignment of a pressurised gas reservoir briefly, for example when starting, can considerably enhance the effect of the lift-increasing and resistance-reducing blow-out device. A light expansion motor, which can possibly be provided and is insertable between pressure gas reservoir and blow-out arrangement, can also multiply the power of the means of propulsion such as drive wheels or air and water screws. <IMAGE>

Title: Apparatus for the automatic laying of spacing laths
Inventor: PRECHTL AUGUST DIPL ING
IPC: B65G57/00
Filed: 1984-03-14
Abstract: An apparatus for the automatic laying of spacing laths is proposed, which is of the same generic type as known apparatuses in accordance with DE-OS 3134387 and, like these, has intermediate magazines which are located above a pile which can be lowered, are filled with spacing laths and from which the spacing laths can be individually delivered to lath guiding pockets which are located below and which take the laths to a position directly above the top pile position, where the laths are then discharged from the lath guiding pockets. In the known apparatuses, the lath guiding pockets are taken by a long lath guiding arm mounted on the magazine in question along a circular arc away from the magazine to a position directly above the top board position. By contrast, in the apparatus according to the invention, the path of movement of the laths from the magazine to a position above the top board position is divided into two sections, first into a purely lifting section and only after that into a relatively short section along an arc, so that significantly shorter lath guiding arms can be used. As a result of this, shorter operating times for bringing down the laths can be achieved, and the individual lath laying stations can also be of narrower construction and can therefore be brought closer together. In the drawing, the intermediate magazines are marked with a 6, the lath guiding pockets are marked with an 18 and the lath guiding arms are marked with a 17. A lifting frame 19 on which the lath guiding arms 17 are pivotably mounted is provided for the lifting movement. <IMAGE>

Title: Diaphragm pump
IPC: F04B43/067
Filed: 1984-06-15
Abstract: A diaphragm pump, in which a volume of hydraulic oil in a cylinder, which communicates with a hydraulic oil chamber which is bounded to one side by a diaphragm, is alternately pressurised and depressurised by the reciprocal movement of a piston with predetermined travel, as a result of which the diaphragm is driven back and forth and thus forces a liquid volume from a liquid chamber on the other side of the diaphragm, and in which pump an excess volume of the hydraulic oil in the hydraulic oil chamber during the pressure stroke is discharged, via a relief valve, into an oil tank, and a volume deficit of hydraulic oil during the expansion stroke of the piston is supplied from the tank, is improved in that the diaphragm pump has a connecting line (31, 33) within the piston (4) between the hydraulic oil chamber (8) and the oil tank (2) and in that a normally closed valve (40) is provided in the connection line, in such a way that said valve is opened as a function of the pressure of the hydraulic oil discharged from the hydraulic oil chamber (8) into the tank or is opened by a reduced pressure generated in the hydraulic oil chamber (8). <IMAGE>

Title: Air outlet for an air-operated refrigerant evaporator of a heat pump
Inventor: KESSELMEYER HEINRICH DIPL ING
IPC: F25D17/06
Filed: 1984-07-07
Abstract: For heat pumps, which draw a part of their energy from the outside air (air/air or air/water heat pumps), the volume flow at the heat-exchange surfaces is of considerable importance. A high volume flow in the air produces an in the main disturbing background noise. In order to check this background noise in its origin, this anti-trumpet system has been developed. By means of the tapering air ducts (see Figs 1-6), the noise breaks up as a result of its spherical propagation on the inclined guide walls. The air flow is not significantly influenced. In Fig. 2, the air flow is constructively adapted to the shape of the noise damper. By means of the narrow cross-section at the outlet of the noise damper, the air flow has a high outlet speed. This push-away effect is necessary and of great importance, in order that the cooled air from the evaporator is pushed away as far as possible.
