Patent DE-3406865-A1 (DE)
Title: Ink jet printing mechanism having a receiving device for rinsing or leaking ink
Inventor: SICKING HEINRICH ING GRAD
IPC: B41J2/17
Filed: 1984-02-25
Abstract: If fresh ink is not ejected constantly from the outlet nozzles of the matrix print heads of ink jet printing mechanisms, the ink situated in the outlet openings is withdrawn into the nozzles and dries up. In order to prevent this drying of ink, the ink supply system and the matrix print head are rinsed with ink at certain time intervals. In this case, in known devices, the rinsing ink is fed to a collection container which has to be exchanged from time to time. The invention is based on the object of considerably enlarging the time intervals for exchanging the receiving device for leaking and/or rinsing ink. This object is achieved in that the ink receiving device consists of a closed container (57) which has openings (61) on its upper side (59), through which openings, in addition to ink vapour, an anti-corrosive agent (56) placed in the container (57) can also escape via the gaseous phase into the machine to form an adsorption film on the metal surfaces. As a result, the interval for changing the collection container (57) for the rinsing and leaking ink is considerably extended, rusting of the steel parts in the machine also being reliably prevented. <IMAGE>

Title: Heat pump installation
Inventor: KEUDELL LEOPOLD VON DIPL ING
IPC: F24D19/10
Filed: 1984-03-07
Abstract: The aim in a heat pump installation is to adjust the bivalence temperature automatically to the loading of the heat pump. For this purpose, the setting of the bivalence temperature is controlled as a function of the storage temperature in such a way that the bivalence temperature is set to the lowest value in the vicinity of the maximum storage temperature that can be achieved by the heat pump. In the case of cold water temperature in the store, the bivalence temperature is set to the highest value. <IMAGE>

Title: Ignition distributor for internal combustion engines
Inventor: BRAMMER HARTMUT
IPC: F16D1/02
Filed: 1984-05-16
Abstract: The ignition distributor shaft (24) is centred at two axially spaced locations (30, 38; 22, 30) in the camshaft (19) of the internal combustion engine and a dog clutch (20, 31) transmits the torque from the camshaft (19) to the ignition distributor shaft (24). The centring locations are formed by the outer portion (30) of the ignition distributor shaft (24), the said outer portion being inserted without play in a recess (30) of the camshaft (19), and a Belleville spring (36), which snaps from its first prestressed position into the second prestressed position when the ignition distributor shaft (24) is inserted. 
<??>As a result, it is not necessary to support the ignition distributor shaft (24) in the ignition distributor housing (10).

Patent DE-3421421-A1 (DE)
Title: Heat exchanger
Inventor: VOELKER WILLI
IPC: F28D7/02
Filed: 1984-06-08
Abstract: Heat exchangers are normally formed from horizontally situated tubes which are provided with cooling fins, air being blow through in a cross flow from the bottom to the top and it being possible to provide thereabove a further spraying device for a liquid evaporation medium. The large volume required is disadvantageous in these known heat exchangers, as also is their price. The invention specifies a heat exchanger, the volume and price of which can be reduced. This is achieved by eliminating the cooling fins and arranging the cooling spiral vertically and by blowing air or a gaseous medium around it in the direction of its longitudinal extent. In order to achieve effective heat exchange, the aim in this case is for the tubes of the tube spiral or spirals to be flattened at right angles to the radius of their coil. <IMAGE>

Patent DE-3425342-A1 (DE)
Title: Articulated tread crank for bicycle
Inventor: ZSCHERNITZ GUENTHER
IPC: B62M1/36
Filed: 1984-07-10
Abstract: Whether a modern bicycle is equipped with or without gears, in any case the present invention permits the same effect to be achieved with less energy. Since the forces which act on the pedal can vary, the spring forces must of course be variable. Tension springs or also compression springs can be used. If the pedal approaches the lower dead-centre point, the spring whose tension is being released will return the previously stored energy to the crank, in which case the lower dead-centre point will also be overcome better than with the previous drive. The length by which the crank is to vary is as variable as the spring force or the respective length of the two crank parts. There are enough possibilities to achieve the best effect for any desired variant. The pedal does not make a circular movement, as was the case previously, but rather a forward oval movement when depressed whilst the upward movement is again a circular one. The transition from the round upward movement to the oval downward movement of the pedal also takes place in a transition-free fashion in the opposite direction.

Title: Coupling of a motor to a gear transmission
Inventor: BARTUSSEK HERBERT
IPC: F16H57/025
Filed: 1985-01-23
Abstract: The invention relates to a device for coupling a small electric motor (1) to a gearwheel transmission (5), in the case of which a coupling element (19) forms an input pinion (21), which can be plugged into the input stage (7) of the gearwheel transmission (5), and a bush (18) into which a motor shaft (4) can easily be pushed and to which a device (23) which engages without rotation play on the pushed-in motor shaft is allocated. In this case, it is desirable for it to be possible to plug the input pinion into the input stage of the gear transmission independently of the motor. This is achieved in that the device, which engages without rotation play, is formed by a freewheeling device (23) which is fixedly inserted into the cavity of the bush (18). The rotationally fixed connection of the motor shaft and the coupling piece are produced simply by pushing the motor shaft into the freewheeling device which is seated in the bush. <IMAGE>

Title: The removable mesh frame in the roof structure
Inventor: BECK ERHARD
IPC: E04D13/17
Filed: 1985-01-31
Abstract: The invention is to ensure a good cost-effective heat insulation in the rafter structure. Holes and slots which let heat escape are to be prevented by a fill of heat-insulating material (perlite fill) between the rafters. The mesh frame is fitted approximately 3 cm lower than the upper edge of the rafters. The said frame has to ensure a through-ventilation between the heat-insulating fill and the roof structure in order that, when damp occurs, the heat-insulating fill can be rapidly dried out again and the insulating value is maintained. The mesh frame comprises two metal frames which are pushed one into the other and on which a fine wire mesh is mounted, with the result that they can be drawn together and pulled apart.

Abstract: A process for the preparation of stable dispersions of finely divided polyisocyanates, and the preparation of heat-crosslinkable isocyanate systems. Stable dispersions of finely divided polyisocyanates in a liquid which may or may not contain surfactants, protective colloids and other assistants are obtained by a method in which polyisocyanates are treated with a stabilizer in the presence of absence of the liquid, and the dispersions prepared from these are finely dispersed and/or milled under the action of high shear forces, if necessary with the addition of further stabilizer. These dispersions are useful as crosslinking agents, particularly for the preparation of heat-cross-linkable isocyanate systems.

Title: Arrangement for forming high-resolution images of structures in solids
Inventor: HUEBENER RUDOLF PETER PROF DR
IPC: G01N29/24
Filed: 1985-07-23
Abstract: The surface of the solid is scanned with a light beam or electron beam or another particle beam. The sound effects caused on the opposite side of the solid are measured by means of two or more sound detectors. The signals can be analyzed by means of an electronic signal processing system. The sound detectors which can be used include superconducting bolometers, superconducting tunnel diodes or piezoelectric transducers. In order to achieve good resolving power, the sound detectors are required to be very small. It is advantageous for the sound detectors to be applied directly to the surface of the solid as thin, preferably vapour-deposited films. In order to detect the spatial position of objects within the solid, at least two sound detectors are provided which are arranged at a small distance next to one another. The intensity of the scanning beam can be modulated and/or pulsed. Additional information is obtained if the phase position of the signals of the sound detectors is measured and the signals are temporally resolved.
