Title: Continuous process for the preparation of microbial metabolic products
Inventor: TROESCH WALTER DR RER NAT
IPC: C12P19/38
Filed: 1987-05-12
Abstract: A continuous process for the preparation of microbial metabolic products by the action of microorganisms on a substrate in a bioreactor is characterised in that porous particulate, spherical or almost spherical support material is introduced into a fluidised bed reactor, a nutrient solution for the microorganisms is continuously passed through the fluidised bed, inoculation is carried out with a preculture of the microorganisms, the microorganisms are cultivated while the nutrient solution is continuously circulated, the circulation generates a fluidised bed of the particulate support material, during which oxygen is passed into the reactor where appropriate or oxygen is admixed with the nutrient solution where appropriate, an aqueous solution or suspension of the substrate on which the microorganisms act is, where appropriate, continuously introduced into the reactor, or the aqueous solution or suspension of the substrate on which the microorganism act is admixed with the nutrient solution, and after a stationary equilibrium has been set up a solution or suspension which contains microbial metabolic products is continuously removed from the bioreactor, and the required microbial metabolic products are isolated in a manner known per se.

Title: Method and device for limiting the room temperature in the case of drive machines which are arranged in closed rooms and develop waste heat
IPC: F25B27/02
Filed: 1987-08-08
Abstract: The invention relates to a method and a device for limiting the room temperature in the case of drive machines which are arranged in closed rooms and develop waste heat, such as, for example, compressors accommodated in halls for compensating the pressure losses of natural gas conducted in pipelines, the waste heat arising being carried off as a waste-gas flow into the atmosphere via a carrying-off arrangement. In order to guarantee, with fault-free operation of the drive machines, an average room temperature even in the case of unfavourable operating conditions, such as, for example, high outside-air temperatures, it is envisaged to arrange a heat exchanger in the flow path of the waste-gas flow, recovering the waste heat which is developed by the drive machines and until now has been unused, which exchanger is connected on the secondary side to the generator or expeller of an absorption refrigeration machine which is provided for room cooling and the cooling output of which can be supplied by a cooling medium of an air-conditioning installation which is provided for the supply of cooled outside air into the room. Preferably, the heat quantity necessary for the operation of the absorption refrigeration machine is extracted from a part flow branched off from the waste-gas flow.

Inventor: DIEHL HANS
IPC: F16B12/20
Filed: 1987-08-13
Abstract: In frame constructions, made essentially of bar-shaped support parts, for use in furniture and interior arrangements, the longitudinal structure and the cross-sectional shape are to be optimised in accordance with the criteria of load distribution over the length of the bars and with aesthetic considerations. Furthermore, the end portions of such support parts are to be designed correspondingly. The support parts have at least two longitudinal portions (1, 2) having different cross-sectional shapes in their outer profiles. In particular, in this case a first longitudinal portion (1) has flat or convexly curved outer surfaces and a second longitudinal portion (2) has concavely curved outer surfaces, preferably with spherical transitional surfaces (2c) between said longitudinal portions. At least one bar end (3) is constructed with a tapered cross-section by means of spherical surface portions (3c).

Title: Method and device for applying pressure to actuators on gearshift elements of a vehicle transmission
Inventor: MUNCKE LUDWIG DIPL ING
IPC: F16H59/46
Filed: 1988-03-24
Abstract: A description is given of a method for applying pressure to actuators on gearshift elements, such as, for example, band brakes or multi-plate clutches of an automatic transmission, especially a vehicle power shift transmission, in which the control pressure imparted to the actuator is varied as a function of operating conditions of the transmission. In order to eliminate transmission faults and to improve the adjustment of the engagement characteristic of the shift element, the slip of the shift element is set to a value adjusted to the respective operating condition of the transmission and/or of the vehicle. A device for performing the method is also described and a hydraulic control circuit for supplying the working chamber of an actuator on a gearshift element, especially one actuated by the method according to the invention, the working chamber of which has a continuous leakage. In this a valve device, by means of which the working chamber can be rapidly filled for activation of the actuator, is connected in parallel to a rapidly responding control valve, by means of which the contact pressure of the gear shift element parts can be purposely influenced. In this way it is possible for the driver to discern a spontaneous reaction of the vehicle when operating the clutch pedal or when operating an automatic reversing switch from forwards to reverse, without thereby bringing the sensitivity and the reaction time of the control valve into question.

Title: Method and apparatus for sample analysis in thin layer chromatography
Inventor: HEISIG WOLFGANG
IPC: G01N30/94
Filed: 1988-07-22
Abstract: The invention relates to a method and an apparatus for sample analysis using a developed or a still to be developed chromatographic plate. In a closable container (5) there is arranged a support plate (3) which is coated or impregnated with a chemical substance (4) suitable for derivative formation or hydrolysis. The container is closed by a chromatographic plate (1) whose layer (2) faces the support plate (3).

Title: Food slicing machine
Inventor: SCHARFEN HERMANN DIPL ING
IPC: B26D7/22
Filed: 1988-08-12
Abstract: A food slicing machine is provided with a circular knife which is partly covered by a hood around its circumference. In the cutting region, a guiding wall adjoins the circular knife and can be adjusted in a parallel fashion, when in the upright position, from a zero position in which its edge close to the knife is essentially aligned with the cutting edge of the circular knife, to permit adjustment of the cutting thickness transversely to the circular knife. In order to prevent, during wiping or brushing of the guiding wall in the zero position, pressure being exerted by the hand behind the cutting plane in such a way that the cutting edge of the circular knife can come into contact with the finger or the thumb, the guide wall is locked in the zero position to the hood of the circular knife.

Title: Motor vehicle with a hydrostatic differential in the drive train of an automatically engaging four-wheel drive
Inventor: BAUSCH PAUL DIPL ING
IPC: B60K17/346
Filed: 1988-08-26
Abstract: The motor vehicle has a four-wheel drive, in which the wheels of one axle are permanently driven and the drive to the wheels of the second axle is automatically engaged at a differential speed to the first axle by way of a four-wheel drive train. A hydrostatic differential (22) with two planetary gear trains, each assigned to a wheel shaft (24) is situated in the four-wheel drive train. The planetary gear trains act as transmission oil-pumping gear pumps, the pump drive torque of which is utilised directly as locking moment of the hydrostatic differential. The latter thus acts both as clutch and mid-differential in the four wheel drive train and as self-locking axle differential of the second axle, which performs the function of a transverse differential lock in the event of slip on the wheels which have been engaged for drive purposes. <IMAGE>
