Title: Multiple circuit heat pump - has two parallel circuits for refrigerant using common double acting compressor and double piston pump
Inventor: ARMONIES GERHARD
IPC: F25B30/02
Filed: 1980-01-26
Abstract: The heat pump which extracts heat from a natural source, has a double piston pump with a main piston (6) which forces the refrigerating medium through a condenser (7) and evaporator (5). The evaporator has another coil in a circuit (1) which circulates the heat supplying medium. The pump has a second piston (10) which circulates the refrigerant through a secondary coil (9) of the condenser and a coil (11) of a heat exchanger. This medium passes through one chamber (13) of a double acting pump which has a second pumping chamber (8) in the first circuit. Between the secondary coil of the condenser and the first pump chamber is a throttle (14). Heat is extruded from the secondary coil (12) of the heat exchanger.

Patent DE-3018790-A1 (DE)
Title: Loudspeaker cone circumferential shaping - has continuous elevation on cone surface to limit lip of circular bead in contact on cone outer edge
Inventor: BRACHT FRIEDRICH WILHELM ING G
IPC: H04R7/12
Filed: 1980-05-16
Abstract: The elevation (12) on the loudspeaker cone limits the connecting surface between the cone (10) and the outer bead so as to form a raised border which preferably extends in a circle parallel to the outer edge of the cone. The elevation can be higher than the subsequent bead thickness, so that during the operation of closing the injection or vulcanising mould used the elevation is compressed and acts as a sealing ring. Further e.g. zig-zag-shaped elevations may be provided, so as to prevent the cone from resting directly on the inside wall of the mould and partially closing the chamber formed. This ensures a flat chamber receiving the liquefied rubber and this can then be calibrated.

Title: Air cleaner appts. for IC engine - has stop valve in air intake line for explosion prevention by operating switch to disable ignition
Inventor: SUZUKI NAGATOSHI
IPC: F02M17/30
Filed: 1980-06-13
Abstract: The air cleaner has the air intake line connected to a cyclo dust collector. An hv generator applies a high voltage to an electrostatic filter. A return-flow stop valve (10) is located in the intake line (11) and opens a switch (9) when it closes. The switch disables the hv generator (7). The stop valve and the switch are sited on the inside wall of the dust collector. The switch is a microswitch. The stop valve is a flap-type valve and has a specified design. The advantage of the device lies in eliminating the risk of an explosion when the engine ignites at the wrong moment and the mixed fuel gas passes from the carburettor near the distributor back via the intake line to the electrostatic filter.

Patent DE-3037652-A1 (DE)
Title: Cam for operating IC engine valves - has section of zero acceleration on opening or closing profile section
Inventor: DESCHLER GERHARD DIPL ING
IPC: F01L1/08
Filed: 1980-10-04
Abstract: The engine has valves which are operated by cams on a camshaft. As the lobe of each cam opens the corresponding valve the cam follower accelerates and then decelerates. The cam profile is laid out so that there is a section (B) of zero acceleration between the accelerating and decelerating sections. This secures the formation of a good lubricating film on the cam surface in spite of high rates of acceleration and deceleration which are required for large valve openings. The zero acceleration section can be either on the valve opening or on the valve closing side of the cam lobe.

Filed: 1980-12-17
Abstract: In order to expose alphanumeric characters and symbols (e.g. pass points, sheet corners, terrain coordinates, place and cadastral names or the like) in orthophotos, a template (15) arranged in the beam path of the optical system (4, 6-11) used for the orthoprojection is sequentially displaced and exposed, while the orthophoto (13) is still in the plotting instrument. The template (15) can preferably be exchanged on the carrier (1), which is displaceable in any case, for the aerial photo (13) to be plotted, and contains all the necessary numerals, letters and symbols. The selection thereof is performed under computer control by moving the image carriage with the template (15) into position with the optical system blanked out after inputting the desired character. The size and writing direction of the characters can be preselected with the aid of the optical system (4, 6-11) for the orthoprojection, which contains inter alia a zoom system (4) and an image-rotating prism (7). <IMAGE>

Title: Process and apparatus for open-end spinning
Inventor: KAMP HEINZ
IPC: D01H1/11
Filed: 1981-05-02
Abstract: To achieve a high production rate at a low outlay in terms of investment and energy, fibres carried and transported by an airstream are conveyed continuously into a stationary elongate fibre-collecting groove (60), from which they are then drawn off continuously from one end, combined to form a yarn (211). The fibres are fed, for example, through a fibre-guide channel (209) which opens out in front of the fibre-collecting groove (60). The fibre-collecting groove (60) possesses side walls which, if appropriate, converge towards the groove bottom (61). The groove bottom (61) can be deaerated continuously, if appropriate positively. A rotation about the longitudinal axis of the yarn can be imparted continuously to the yarn (211) in the fibre-collecting groove (60) or in its vicinity. <IMAGE>

Title: Fire-retarding insulating materials and process for producing them
Inventor: DORN KARLHEINZ DIPL CHEM DR
IPC: C04B22/00
Filed: 1981-10-23
Abstract: The invention describes insulating materials of high heat absorption capacity, based on known insulating materials such as vermiculite, perlite, pumice, glass wool, rock wool or basalt wool or also asbestos. The heat transmission through insulation layers of such materials is greatly impeded by impregnation of the insulation materials known per se with combinations of salts containing water of crystallisation and Portland cement. Those salts containing water of crystallisation are preferred which are non-aggressive and non-toxic and which do not release any harmful substances on heating. Such fire-retarding insulation materials are produced either by impregnating porous, granular materials with melts of inorganic salt hydrates and Portland cement, or by impregnating two-dimensional, commercially available insulating materials with solutions of the salts containing water of crystallisation and Portland cement, and subsequent drying to the water content of the corresponding salt hydrates. In addition, the production of fire-retarding insulation materials by pressing the impregnated, granular insulation materials is described.

Title: Chuck for drilling machines or the like
Inventor: ZETTL OTTO
IPC: B23B31/12
Filed: 1981-11-06
Abstract: A chuck, in particular for drilling machines, has two clamping rings (18, 22), of which one is fastened to a rear grip-sleeve collar (14) in such a way as to be locked in terms of rotation, while the other is attached to a fastening sleeve (20) in such a way as to be locked in terms of rotation, which fastening sleeve (20) can be rotated relative to the grip sleeve (12). The rear end face of the clamping ring (18) is designed as a catch rim, and a catch pin (26) is displaceable in the other clamping ring (22), which catch pin (26) interacts with the catch rim of the first clamping ring. The catch pin (26) can be locked in the catch position by means of a locking device (30). Thanks to the catch device, the chuck can no longer open by itself and is therefore suitable for clockwise and counterclockwise rotation. <IMAGE>
