Title: Sepn of solids from sludge - uses controlled feed of flocking polymers according to measurement of cloudiness
Inventor: GUDJONS HELMUT
IPC: G01N15/06
Filed: 1992-10-30
Abstract: To separate fluids and solids from sludges with a low solids content, flocking polymers are added according to the measured cloudiness of the liquid. The cloudiness is measured before and after the polymer addition, and the amount of polymer added is controlled according to the two measurements. The polymer feed is controlled according to the cloudiness measurement where the initial measured value is known and constant and the measurement value after polymer addition it taken as the feed control value. The cloudiness measurements are taken at a separate pilot container, filled in charges, with the polymer addition at the main system parallel to it. The cloudiness measurements can be taken in the flow at the main system, where the flow speed gives flocking development time before reaching the second. USE/ADVANTAGE - The system is for the processing and disposal of sewage, where the polymer additive assists flocking of the solids for separation. The operation gives min. consumption of the polymer material for a simple and trouble-free action.

Abstract: PCT No. PCT/DE94/00047 Sec. 371 Date Aug. 28, 1995 Sec. 102(e) Date Aug. 28, 1995 PCT Filed Jan. 22, 1994 PCT Pub. No. WO94/18357 PCT Pub. Date Aug. 18, 1994An apparatus for producing solid fine particulates has a substantially closed reaction vessel and a hollow gas input conduit inside the vessel formed with a multiplicity of similar outlet apertures each having a flow cross section of at most 2 mm2. The conduit has an overall cross-sectional area equal to at least 100 times the flow cross section of a one of the apertures. A foraminous structure in the vessel surrounds the conduit and an electrode is provided in the vessel outside the foraminous structure. A direct-current power supply has a negative side connected to the foraminous structure and a positive side connected to the electrode while the input conduit is at ground potential so that a glow discharge is created in the vessel between the foraminous structure and the electrode. Input gases selected from the group consisting of gaseous metal chlorides, hydrogen, oxygen, nitrogen, and a carbon-containing gas in a mixture reacting in the presence of a glow discharge to produce particles are introduced into an interior of the conduit and gases are withdrawn from the vessel from outside the foraminous structure so that particles are freed from the input gases by the glow discharge and deposited in the vessel.

Title: Electric power steering system
Inventor: STOCK HANS DIPL ING
IPC: B62D5/04
Filed: 1993-02-09
Abstract: Power steering systems have previously been realised in a hydraulic way. This means a high technical expense. In addition, a hydraulic pump which is continuously in use is necessary. Adaptation to the vehicle characteristics, speed and road conditions is only possible to a certain extent. The new electric steering system gives rise to a simple design. The steering properties can be adapted to the requirements electronically. Previous concepts of electric steering systems are based on an electric motor. Either the motor must be accelerated or braked when required or clutching and declutching must occur with the motor running continuously. This results in premature wear and control delays. The novelty on which the invention is based is the application of the power assistance directly in the axial direction, in small steps. The indicated movement sequence can be applied in the field of steering gear (automobile industry) and in manually guided pressing operations. <IMAGE>

Title: Method for measuring the current gas bias pressure in a hydropneumatic store
Inventor: WEBER NORBERT DIPL ING
IPC: G01L19/00
Filed: 1993-06-19
Abstract: The invention relates to a method for measuring the current gas bias pressure poact of a gas which can be accommodated in a hydropneumatic store 10, in which a gas-conveying connection 18 is produced between the store 10 and a chamber 16 which has a fraction of the storage volume and can be closed off by means of a closing device 24. As a result of the fact that, by means of a pressure value pick-up 22 arranged between the store 10 and the closing device 24, the gas pressure px in the store 10 is measured with a closed-off connection and, after opening the connection 18, the accompanying pressure change py is measured, and the fact that the current gas bias pressure poact is determined from the pair of pressure values px, py obtained in this manner, the actual gas bias pressure in the case of a hydropneumatic store can be reliably and accurately registered using means of simple construction and using only one single measuring process and, consequently, a statement can be made as to the operating condition of the store. <IMAGE>

Abstract: The invention relates to a novel design of a guide tool for use when installing insulating panels into a masonry wall, which insulating panels, after installation from an installation side of the masonry wall, adjoin one another in an overlapping manner at border regions and consequently form a moisture-barrier layer in the masonry wall. The guide tool, which can be introduced into the masonry wall with the front side in front, exhibits two guides, of which one can be used for receiving the border region of an insulating panel which has already been inserted and the other serves for receiving and guiding the border region of the insulating panel which is to be driven in, the guides exhibiting open front and rear ends, offset in the longitudinal direction of the guide tool, and slit-like open sides which extend in said longitudinal direction and are open to opposite sides of the guide tool.
Patent DE-4321118-A1 (DE)
Inventor: HEGENDOERFER MAX DIPL ING
IPC: H03J1/00
Filed: 1993-06-25
Abstract: Transmitter search controllers are known in which the levels of the received transmitter signals are compared with a predetermined threshold value. If the level of the received transmitter signal exceeds the threshold value, the transmitter is classified as suitable for receiving and the transmitter search is ended. The known transmitter search controllers have the disadvantage that they cannot be adapted to specific receiving conditions. The present invention avoids these disadvantages by the fact that the response threshold is fixed according to the disturbances present. <IMAGE>

Title: Measuring tension in strings of tennis, squash and badminton racquets
Inventor: ANDERKA GEROLD
IPC: A63B51/005
Filed: 1994-03-25
Abstract: A test device is attached to the upper side of the strings by an attachment device by clamping the strings between an attachment part and a housing so that when pressure is applied to a pressure point (14) a pressure surface (7) and the striking surface (4) contact each other, thus exerting a force on a pressure sensor (15) mounted between a pressure plate (5) and the housing (1). This results in a corresp. resistance value being processed in evaluation electronics. The resistance value can be transferred to the evaluation electronics as an analogue value. The analogue signal can be converted into a Newton indication and hence into a digital signal.
