Title: Continuous degassing of borehole drilling mud with air excluded - provides information on gas bearing rock formation contg. the borehole
IPC: E21B21/06
Filed: 1990-07-25
Abstract: This is an arrangement for the continuous degassing, by producing an underpressure, of liquids with or without solid particles, in particular drilling mud, shut off from the surrounding air. Arrangement, intended for analytic purposes, includes the liq. being fed into the inner (2) of two cylinders, where it is ground, whirled around, centrifuged (10) and thrown over the top of this cylinder (2) down into the outer cylinder (1). Outer cylinder forms a low-pressure chamber and is open at the bottom, which is in a tank (14). This cylinder has, at the top, a gas outlet pipe (4) connected to a pump (15) that produces an underpressure in the cylinder (1). This degassing system is downwardly shut off from ambient influence, and solid particles can fall into the tank (14). USE/ADVANTAGE - Drawbacks both of discontinuous and of other continuous systems for use with such analyses are overcome.  Test measurements, together with analysis of the gas, enable quantitative and qualitative information on the gas-bearing rock formation contg. the borehole to be obtd.

Title: Spinning or twisting ring magnet bearing - has permanent magnet ring and electro-magnetic system for accurate radial stability
Inventor: STAHLECKER HANS
IPC: D01H7/56
Filed: 1991-02-05
Abstract: The magnet bearing, for a ferro-magnetic rotor as a spinning or twisting ring (4) rotated by friction movement of the yarn (2), is concentric to the spindle with a permanent magnet ring (6) and the electro-magnetic system (14). This forms a deflection guide for the yarn (2) fed in the axial spindle direction to be wound round the bobbin (1) on the spindle. The spinning or twisting ring (4) is a cylindrical sleeve with an axial length at least half its dia. The lower end side (20) of the sleeve acts as the deflection guide for the yarn (2). A space (5) between the permanent magnet ring (6) and the spinning or twisting ring (4) gives a passage for the fed yarn to pass through, and the ring (4) can have a carrier passage for the yarn (2) as an opening leading in from the outside. Sensors (11) are located at one end side of the ring (4) and the electro-magnetic system is at the other end. Three to eight sensors (11) are located equidistantly round the periphery. The electro-magnetic system (14) has at least four segment coils (17) on a ring-shaped core (15), in opposing pairs linked together. A ballooning limiter (21) is in front of the spinning or twisting ring (4) in the direction (A) of yarn (2) travel, and a locking ring (27) is below the spinning or twisting ring (4). The ballooning limiter (21) and/or the locking ring (27) are of a non-magnetic material. ADVANTAGE - The appts. gives a radial stability with high accuracy, using a floating ring held without contact.

Title: Oil binding agent for clearing oil contaminated waters etc. - consists of granular comminuted expanded and foamed polystyrene
Inventor: GEISS MARTIN
IPC: C09K3/32
Filed: 1991-03-30
Abstract: An oil binding agent esp. for treating oil-polluted water, whereby the agent acquires its oil binding properties only after mechanical processing (mechanical comminution by pulverising, rupturing, cutting or milling) of the Styropor (RTM; expanded foamed polystyrene) raw material into 1-3 mm. sized individual pieces forming the end prod. which is spread onto the contaminated water or introduced below its surface (in the loose state or packed into water-permeable containers forming part of a larger unit), whereby the oil is sepd. from the carrier liq., its tendency to stick disappears and it clumps together with the agent and floats on the surface of the water so that it can be gathered up or otherwise removed. USE/ADVANTAGE - The comminuted polystyrene foam has high binding capacity for oil, is rot-proof, non-environmentally polluting, floats on water, takes the stickiness out of the oil so that it is no longer harmful to fauna, flora, land, human beings etc., is non-aggressive and non environmentally polluting. The cleaning agent has no affinity for water or other materials to be freed from oil pollution and can therefore be used for decontaminating water or oil-contaminated surfaces such as human skin, beaches, the bodies of animals, tanks, plants etc

Patent DE-4112410-A1 (DE)
Inventor: MEINERT KLAUS
IPC: F16H9/26
Filed: 1991-04-16
Abstract: Prior art transmission with positively interlocking parts suffer from the disadvantage that they cannot be varied continuously. This results in complicated shift procedures and losses in power. The aim of the invention is to propose a transmission with positively interlocking parts which is also continuously variable. Thisaim is achieved in principle by virtue of the fact that the transmission is fitted with an adjustment wheel with a continuously variable radius of action. In order to simplify the design of the transmission, this radius of action is limited to the zone of load contact and is therefore only virtual. A simple embodiment of an adjustment wheel of this kind comprises a combination of a central pinion (8) with a transmission chain (7), the curvature of the transmission chain (7) within the zone of load contact, and hence the radius of action effective in this zone, being ensured by an adjustable body (12, 13) which preferably comprises two adjustable bevel gears.

Title: Sediment elasticity measurement - has centrifuge speed varied by computer on time scale for image on screen to be converted into signals for computer evaluation
Inventor: LERCHE DIETMAR PROF DR SC NAT
IPC: G01N15/04
Filed: 1991-05-15
Abstract: To measure the elastic characteristics of sediments from suspensions and emulsions, the sediment is subjected to a centrifugal field which is varied on a time scale. At the same time, it is illuminated in a transparent light field for the image to be presented on a high definition line screen to show the light density change in the test sample. This is taken as a measure of the phase limit progression, to be converted into electrical signals for computer processing. The variation in the centrifugal field is set by a computer which modifies the rotary speed of the centrifuge. The conversion of the light density change into electrical signals is repeated in a cycle which is asynchronous to the image screen cycle, controlled by a trigger pulse synchronised with the centrifuge rotation. USE/ADVANTAGE - The technique is primarly for medical diagnosis and biotechnology processing. It allows the elasticity of sediments to be established.

Title: Power operated three-jaw chuck for machine tool - has compact wedge type coupling to translate axial movement of plunger into radial clamping movement of jaws
Inventor: GULDE SIEGFRIED
IPC: B23B31/177
Filed: 1991-11-14
Abstract: The chuck jaws (11) are guided in a chuck body (10) secured to a backplate (19).

In the region of the jaws (11) and their wedge pieces (16) the plunger (12) is supported at two axially separated sections, one in the baseplate (19) and one in the chuck body (10), to prevent tipping of the plunger. The inclined shoulders (14) of the jaw wedge pieces slide through inclined slots (17) in the plunger, providing a large bearing area for transmission of the clamping force. USE/ADVANTAGE - Short compact power-operated three-jaw chuck has high ratio of clamping force to actuating force.
