Patent DE-3237360-A1 (DE)
Title: Operating device for an electronic unit
Inventor: HANAJIMA MITSURU
IPC: G05B19/10
Filed: 1982-10-08
Abstract: The functions of an electronic unit, such as a cassette recorder, are totally or partially controlled by the actuation of switches. The control device for the unit comprises a memory for storing control information, setting devices, for example switches, for input of the control information, a locking or holding memory to control the operating condition of the unit on the basis of the control information supplied from the memory or the setting devices to the locking memory and to maintain the respective operating condition of the unit, a display device to display the setting information and to display the information resident in the locking memory, and a change indicator to display changes in the setting values. The setting information stored in the memory can be monitored through the actuation of a monitoring switch. The setting information stored in the memory is in this case displayed without changing the respective set operating condition. If the operating condition is changed by means of a setting operation after the information previously stored in the memory has been transferred to the locking memory to control the operating condition, with the result that the new contents of the locking memory, i.e. the operating condition to which the unit is currently set, does not correspond with the information stored in the memory, this state is displayed by the change indicator. The user is thereby alerted to the fact that the setting information has been changed. The correct operation of the unit is simplified as a result of this measure.

Title: Hydrodynamic drive by a two-stroke diesel engine with opposing free pistons and hydraulic pump
Inventor: WAGNER ALBERT
IPC: F02D13/00
Filed: 1982-10-14
Abstract: In this drive the reciprocating movement of the free pistons of the diesel engine is translated into rotary movement by the pressurised water delivered by the hydraulic pump with a counter-pressure free jet turbine 100. Of simple construction without crank drive and cylinder head, and with complete mass balancing in each cylinder, quiet running and low friction and cooling losses, this drive has the advantages compared to known four-stroke diesel engines that the power-to-weight ratio and the specific fuel consumption are lower because the counter-pressure free jet turbine is lighter at high delivery pressures and high speed and has a higher efficiency than the crank drive. For automatic regulation of the injection quantity by the delivery pressure of the hydraulic pump the speed is regulated in the counter- pressure free jet turbine by adjustment of the nozzle needles and by switching of the diesel engine. The pilot pressure in the return line required for the hydraulic pump is held by compressed air in the closed housing of the counter- pressure free jet turbine. The simple and robust counter-pressure free jet turbine comprises a housing with two or four nozzles, an adjusting device and an impeller.
Patent DE-3248537-A1 (DE)
IPC: E01C7/08
Filed: 1982-12-29
Abstract: Quartz sand molded elements, obtainable from dry quartz sand by the action of a high voltage electrostatic field due to the orientation and optionally the electrostatic charge of the quartz sand grains in the electric field, and to the sintering in the orientation state thus obtained. A particular advantage of the method is that neither a binder nor water to consolidate the sand matrix is required. The plant according to the present invention comprises substantially a field device to apply an electrostatic field to the quartz sand and a downstream sintering furnace and, if necessary, a desiccator and a conveyor upstream of the field device. The molded elements according to the present invention are characterized by a high mechanical strength and a high porosity, as well as by excellent sound damping and thermal insulating properties. They may be conveniently used in many application fields, particularly as building materials and as a substitute for gravel.

Title: Process for the production of aluminate lye from agglomerate containing alkali metal aluminates
Inventor: ARONZON VITALIJ L VOVIC
IPC: C01F7/04
Filed: 1983-01-28
Abstract: The invention relates to process engineering involving the extraction of useful components from solids into solution. The invention is based on the leaching of the agglomerate (1) with a recycled lye (2) from the production of alumina and a weak alkali lye (3), to obtain a suspension (4), whose liquid phase represents the aluminate lye (5). The process also comprises multistage washing of the solid phase (6) of the suspension (4) in countercurrent, obtaining a wash water (9) at every stage of the wash (C1, C2, ..., Cn), and also obtaining, in the first stage (C1), a weak alkali lye (3), and in the last stage (Cn), the leached sludge (10). The quantities of the materials introduced into the leaching process are set as follows: agglomerate (1) - proportional to the sum of the mass flow of the recycled lye (2) and of the weak alkali lye (3); recycled lye (2) - proportional to the mass flow of the weak aqueous alkali metal hydroxide (3); weak alkali lye (3) - proportional to the content of caustic soda in the leached sludge (10). The sum of the volumes of the solid phase (6) of the suspension (4), and of the wash water (9) is kept constant either by changing the mass flow of the wash water (9), which is supplied to the stage in question of the wash, or, in the last stage (Cn), by changing the amount of the water (7) which is supplied to the wash process. The concentration of the caustic soda in the aluminate lye (5), the alkaline ratio of the aluminate lye ... Original abstract incomplete. <IMAGE>

Patent DE-3316938-A1 (DE)
Title: Apparatus for heating water by means of a heat pump
Inventor: KANTNER ALEXANDER DR RER NAT
IPC: F25B39/04
Filed: 1983-05-09
Abstract: Hot water can be prepared by means of a hot water heat pump. This takes place by direct condensation or via tertiary circuits. Usually single compressor appliances of low power are used. Large hot water tanks with long heating-up times, stand-by losses, large space requirements and high plant costs are required for this. Supplementary electrical heating systems have to be involved at peak periods. Furthermore, heating heat pumps can be used for hot water preparation. Single-compressor appliances of high power are usually used for this. The hot water preparation takes place via tertiary heat exchangers, which are situated within or outside the hot water tanks. The large compressor power, the small transfer surfaces, the cyclic operation, the coupling of the heating circuits to the hot water circuits, and the switching off of the heating circuits during the preparation of hot water are disadvantageous. According to the invention, a heat pump 2 is used for the parallel production of heating water and hot water via a double condenser system 11,12 with thermodynamically progressive behaviour. The double condenser system includes two condensers 11,12, which are connected in series on the refrigeration circuit side. On the water side, each condenser 11,12 has an independent water circuit 14,19. The condenser 11 connected downstream of the compressor 7 serves for hot water preparation, and the condenser 12 connected downstream of the hot water condenser 11 serves for the heating of heating water. <IMAGE>

Title: Process and apparatus for separating fat/water and/or oil/water emulsions
Inventor: BELHAZY ISTVAN
IPC: B01D17/04
Filed: 1983-10-03
Abstract: Process and apparatus for separating fat/water and/or oil/water emulsions, the water envelope surrounding the fat and/or oil droplets of the emulsion being disrupted so that the combined fat and/or oil droplets are floated to the surface of the emulsion and are eliminated there - expediently by skimming. According to the invention, part of the emulsion is converted into a continuous liquid skin, which has a velocity such that it can penetrate into the remaining part of the emulsion through its free surface. This liquid skin - expediently at an acute angle - is shot onto the free surface of the remaining part. According to the invention, a generator of rotation arranged above the emulsion surface is used to disrupt the water envelope of the fat and/or oil droplets of the emulsion, which generator of rotation has a cylindrical hollow upper part, a tangential inlet port connected thereto, a downwards tapering - expediently conical - lower part connected to the upper part from below, and a downwards-expanding outlet element connected to the bottom end of the lower part. With the aid of the process and the apparatus according to the invention, a more efficient emulsion separation can be achieved with a considerably smaller specific energy consumption in comparison to that achieved hitherto.
