Patent DE-4212187-C1 (DE)
Title: Continuous fermentation to produce e.g. acetone@, methanol etc. esp. acetic acid - where substrate addn. is controlled in 1st fermentation unit and material is introduced in 2nd unit, to form prod. which is then micro- and/or ultra-filtered
IPC: C12J1/10
Filed: 1992-04-10
Granted: 1993-04-15
Abstract: Continuous fermentation is carried out in two fermentation units. In the first, substrate addition is controlled to give a constant substrate concn. and so a constant product concn. In the second fermentation unit, material is introduced from the first ferementation unit at a caculated bleed rate. The product is removed from both units by microfiltration and/or ultrafiltration units, the retentate being returned to the system, with part of the stream from the second fermenter being removed from the system. The product is obtained from the permeate conventionally, e.g. by electrodialysis, reverse osmosis or pervaporation. The process is controlled by the mass guidance control system. USE/ADVANTAGE - Used for the prodn. of butanol, methanol or acetone, or for producing citric, lactic, tartaric, succinic, oxalic, malic or fumaric acid, and esp. for aceticacid prodn. with increased yield.

Title: Device for automatically setting an optimum operating point for the operation of a load on a voltage source
Inventor: REUSTLE HANS DIPL ING
IPC: H02M3/335
Filed: 1993-12-22
Granted: 1994-12-22
Abstract: A switching regulator (SR) is provided for automatically setting an optimum operating point for the operation of a load (V) on a voltage source (QV). The duty ratio of the control signal for the actuator (SG) of said regulator is modulated and the deviation of the output voltage ( DELTA UA)/of the output current ( DELTA IA) or of the output power ( DELTA PA) of the switching regulator (SR) on account of this modulation is evaluated. By means of a changeover device (MO), the deviation ( DELTA UA,  DELTA IA,  DELTA PA) is switched, alternately inverted and non-inverted, to an integration element (IG). The duty ratio is influenced in such a way that the deviation from a desired value is minimal. The device is particularly suitable for operation on greatly fluctuating voltage sources, for example solar cells, or on voltage sources whose properties are not known, for example remote power feeding devices. <IMAGE>

Title: Process for the stepwise construction of microstructure elements, and microstructure elements produced by this process
Inventor: SCHUBERT KLAUS DR
IPC: B29C67/00
Filed: 1994-01-07
Granted: 1995-01-12
Abstract: The invention relates to a process for the stepwise construction of microstructure elements (and to a microstructure element produced in this way), by lithographic methods, in which radiation-sensitive layers are built up one on top of the other to a height to form a solid stack, where each layer, after addition to the stack, is irradiated through a structured mask, and where the irradiated areas of the layers are removed by means of a developer solution. After irradiation of each layer, its entire free surface is metallized, apart from the free surface of the layer applied last; the radiation-sensitive layer accessible to the developer solution is then developed, and the metal layer on the surface, partially uncovered by the development, of the underlying radiation-sensitive layer is removed by etching.

Title: Device for cooling a traction battery
Inventor: BOLL WOLF DR ING
IPC: H01M10/613
Filed: 1994-03-16
Granted: 1995-04-27
Abstract: For such battery cooling it is on the one hand known for an air/water heat exchanger to be used as long as the ambient temperature is significantly below the required battery temperature. On the other hand, it is known for the battery to be cooled by a cooling unit of a vehicle air-conditioning system by the battery serpentine cooling coil being connected into the cooling circuit of the air-conditioning system downstream of the evaporator in said air-conditioning system. Devices are proposed in the case of which either the battery serpentine cooling coil is inserted into the vehicle air-conditioning system cooling circuit with an upstream expansion valve in parallel with the evaporator branch of said vehicle air-conditioning system, or a cooling circuit having an air/water heat exchanger is used, a further cooling unit then being provided whose evaporator is in thermal contact with this cooling circuit and can be activated as required. In this way, the desired battery temperature is maintained at a low cost in terms of line and cooling components in all environmental conditions, in particular when the ambient temperature is higher than the required battery temperature, as well. For use, for example, for cooling the traction battery of an electric vehicle.

Abstract: FIELD: fabrication of composite ceramic articles. SUBSTANCE: method involves relative orientation of the body of main metal and permeable mass of refractory filler material to form products of oxidation reaction, heating in gaseous oxidizing fluid at a temperature higher than the melting temperature of the main metal, but lower than the melting temperature of the product of oxidation reaction for 10 to 95 hours, and holding in gaseous oxidizing fluid at this temperature for 2 to 400 hours for the metal and the product of its reaction with gaseous oxidizing fluid to penetrate the mass of filler material. The first source of main metal is formed from the main metal and tank containing molten main metal communicating with first source to be replenished as the metal is depleted for oxidation reaction from the tank of molten main metal. Used as the main metal is titanium, or zirconium, or silicon, or tin, or aluminum alloy. Used as the aluminum alloy is an alloy of aluminum with magnesium, silicon, chromium, zinc, and iron taken in the quantity of 0.1-13 mass per cent each. Used as the refractory material is an oxide, nitride, boride, or carbide. The refractory material has preferably the form of powder, or granules, or fibers. Used as the gaseous fluid is air, or nitrogen-containing gas. A layer of solid oxidant is applied to the surface of the first source of main metal in the form of aluminum alloy. Mold can be introduced to the permeable mass of filler material. At least part of the surface of the permeable mass of the filler or mold is confined by a barrier acting to prevent formation of metal and product of reaction with gaseous fluid.

Abstract: Сущность изобретения: регулятор вакуума состоит из корпуса, в котором расположен полый клапан, имеющий в плане форму клина с боковыми стенками и торцевыми стенками, подвижно соединенными при помощи направляющих с корпусом. В основании клапана закреплена мембрана. Клапан снабжен компенсатором давления и сильфоном, который сообщен посредством щелевого канала с полостью клапана, а посредством трубки с компенсатором давления. Основание сильфона совмещено с корпусом. При включении вакуумной установки происходит отсос воздуха. С увеличением давления мембрана и сильфон выпрямляются, клапан опускается, боковые стенки расходятся в стороны, тем самым зазор между клапаном и выходным патрубком уменьшается. При достижении равенства давлений в объеме клапана и объеме, заключенном в корпусе, клапан перекроет доступ вакуума. Вакуум в системе стабилизируется и автоматически поддерживается в заданном пределе путем увеличения или уменьшения зазора прохождения отсасываемого воздуха вплоть до его полного перекрытия и отключения источника вакуума от регулируемой системы. 2 ил.
