Title: Series-connected thin-film solar module made from crystalline silicon
Inventor: KRUEHLER WOLFGANG DR RER NAT
IPC: H01L31/056
Filed: 1987-08-20
Abstract: In order to produce a series-connected thin-film solar module made from crystalline silicon, it is proposed to produce the solar cells directly on a large-area substrate (1) (glass, plastic or ceramic) of approx. 1 m edge length, using an integrated process. Narrow webs (2), already provided on the substrate, separate strip-shaped individual solar cells (4) of approx. 1 to 2 cm width from one another. The front electrodes (7), produced using the screen printing process, also produce the series connection via contact trenches (grooves, moats) (6). Material costs are saved in conjunction with a high efficiency, and the use of large-area substrates (1) is permitted. <IMAGE>
Patent DE-3729088-A1 (DE)
Title: Shearer loader or selective-cut heading machine for underground operation
Inventor: WEBER KARL-HEINZ DIPL ING
IPC: G05D23/19
Filed: 1987-09-01
Abstract: During their operation, shearer loaders are continuously supplied with liquid which is mainly used for dust suppression and to a lesser extent also for cooling the electrical devices. The portion of liquid used for the cooling can no longer be sprayed via the nozzles of the cutting drums on account of the high pressure loss which it sustains when passing through the coolers. Consequently, it reduces the liquid volume available to the shearer loader for the dust suppression. In order to reduce the liquid volume required for cooling the electrical devices (4, 9), these devices (4, 9) of the shearer loader (1) are equipped with sensors (14) detecting their temperature. If a temperature value lying above the dew point is exceeded, they trigger a signal proportional to the respective temperature and actuate by means of this signal a regulating device (13) which causes a valve (12) lying in the liquid line (11) to deliver a liquid volume proportional to the respective temperature. <IMAGE>

Title: Ventilation system for extracting waste air from rooms
Inventor: BAUER GERHARD
IPC: F24F7/00
Filed: 1987-09-26
Abstract: The ventilation system comprises a ventilation unit which is arranged beneath a double-sashed window and has in each case one waste-air duct and one warm-air-current duct which can selectively be switched to the interspace between the outer glazing and the inner glazing of the window, the respectively other duct being shut off with respect to the window interspace. When the waste-air duct is shut off with respect to the window interspace, a static quantity of air, which has an insulating effect and helps to avoid air losses, is enclosed between said shutting-off arrangement and at least one non-return valve which is located in the duct and, when waste air is flowing out, is made to move by the same into its opening position and passes automatically back into its closed position. When the window interspace is switched to the warm-air-current duct, a current of waste air flows continuously through the window interspace, with the result that, in the window interspace, no condensation water precipitates from the room air, and the panes of glass are thus not misted up.

Patent DE-3838608-A1 (DE)
Title: Process and arrangement for determining a process variable in the heat treatment of metal parts
Inventor: NOWACK GERD DR ING
IPC: G01R27/00
Filed: 1988-11-15
Abstract: To determine the carbon concentration of metal parts during their heat treatment with mass transfer, an electrical resistance measurement is carried out on the metal part (1) using alternating current and is repeated at various frequencies. From the sequence of the selectively measured resistance values at the various frequencies, a carbon concentration profile is obtained as a function of the distance from a surface of the heat-treated metal part. After determination of the carbon concentration at the metal part surface, the average carbon concentration in successive layers is determined iteratively using a computerised evaluation facility (15, 20). If the carbon content is kept constant during the heat treatment, the temperature distribution in the metal layers can also be determined from the resistance distribution in the metal part. <IMAGE>

Patent DE-3842734-A1 (DE)
Inventor: BAUER ALEXANDER DR
IPC: G01N33/18
Filed: 1988-12-19
Abstract: In order to protect the biological processing stage of a sewage-treatment plant from disruption caused by bacterial poisons in the waste water, the water must be continuously monitored for components which will inhibit the action of the bacteria and thus have an adverse affect on the sewage-degradation process. This is done by diverting part of the waste-water stream to a measurement station where one of the total-load parameters, such as the chemical oxygen demand, total organic carbon or biochemical oxygen demand, is determined. Another part of the waste-water stream is mixed with an oxygen-rich bacterial-sludge suspension and the resulting mixture passed through an oxygen-measurement station where the oxygen-uptake value  DELTA pO2 is measured. The oxygen-uptake value and the value of the total-load parameter are used to calculate a dimensionless oxygen-consumption coefficient characteristic of the waste water and largely independent of fluctuations in load.

Title: Oil cooler
Inventor: BROST VIKTOR DIPL ING
IPC: F28F9/00
Filed: 1989-01-31
Abstract: An oil cooler has a two-part housing through which water is guided, and in the housing a cooling block made from plate-shaped flat tubes through the interior of which the oil to be cooled is guided. Partitions which are directed transverse to the direction of flow of the cooling medium and to the plane of the flat tubes are arranged in the respective lateral gap between the outside of the cooling block and the adjacent wall of the housing. The partitions are formed on the inside of the housing from webs which are integral with at least a part of the housing, project inwards and bear against the outside of the cooling block approximately only by means of linear contact. The webs consist of beads. The latter reduce a bypass in the gap on the water side and permit compensation of manufacturing tolerances, doing so without additional, costly separate parts.
