Patent DE-3564328-D1 (DE)
Title: Flow rate control valve
Inventor: VAN RENSBURG GERT NEL JANSE
IPC: F16K15/04
Filed: 1985-04-03
Granted: 1988-09-15
Abstract: A non-return valve comprises a main housing 10 and an auxiliary housing 14 in which a ball 18 is entrapped. Flow can only take place from left to right and during flow the ball 18 is free to rotate causing self cleaning of its surface. The ball 18 may be pressed down to turn off the valve completely, or to partially throttle the valve, by a controllable mechanism 20 which urges a dish 24 against the ball 18.

Title: Process and device for cleaning a gas stream containing solid or liquid particles in suspension
Inventor: ELIASSON BALDUR DR
IPC: B03C3/38
Filed: 1985-11-30
Granted: 1989-03-02
Abstract: A method and device for removing solid or liquid particles contained in suspension in a gas stream by an electric field, wherein the gas stream flow is directed past ion sources which simultaneously act as field electrodes. The suspended particles are thereby changed in a bipolar manner, such that approximately half of the particles are positively charged and the other half negatively charged, and are forced by the electric field to migrate across the gas stream into a preferred neutralization zone where they are concentrated, discharged, partially agglomerated and coagulated. Subsequently, the particle-enriched and particle-depleted partial gas stream thus formed are separated and treated further in accordance with operating requirements. Thereby the remaining gas stream maximally loaded with particles is fed into a particle-removal device where their withdrawal occurs. The device results in a considerable reduction in the gas volume carried along up to the fine-cleaning stage, and a decrease in cost of the electrofilter by a factor of two or more.

Title: Traction and guidance system for driverless carriage units
Inventor: BOGLI PETER
IPC: G05D1/02
Filed: 1985-05-14
Granted: 1989-08-03
Abstract: Each transport device contains at least two drive wheels which are driven at individual speeds VA and VB and which are pivotable by related steering angles  alpha  and  beta . Identical servo-drive units are associated with the drive wheels and their mode of operation and mutual coupling is adapted by switch devices to the steering angles  alpha  and  beta  such that the required speed adjustment must not be computed in accordance with the relationship VB=(cos alpha /cos beta ). VA but the speed is automatically adjusted through the entire steering angle range of -90 DEG  to +90 DEG . At alpha = beta =0 DEG  the leading servo-drive unit is rigidly guided by its speed regulation loop as a MASTER servo-drive unit and its armature current is supplied as a reference magnitude to the armature current regulation loop of the trailing servo-drive unit which is operated as a SLAVE servo-drive unit. At  alpha = beta =+/-90 DEG the two servo-drive units operate as independent MASTER servo-drive units and their speed regulation loops receive related reference speed signals from related microcomputers. Throughout the steering angle range of -90 DEG  to +90 DEG  the MASTER/SLAVE configuration and the MASTER/MASTER configuration are selectively used depending on the operating conditions and the travel durations. The optimum adaption of the servo-drive units to the steering angles and the limitation of the speed to the maximum speed which corresponds to optimum efficiency, insure precise track guidance, improved maneuverability and minimum current consumption.

Abstract: The connecting element is an electrically weldable sleeve (1) which has a sleeve body (2) and a heating wire winding (3) with heating elements (4, 5) and terminals (8, 9) for the supply of electrical power. Conduit ends (6, 7) are inserted in the sleeve (1). To weld the sleeve (1) to the conduit ends (6, 7) a fusing zone is generated electrically in the heating elements (4, 5). In order to position the heating wire turns (10) of the heating elements (4, 5) precisely and, during welding, to avoid adversely affecting the welding power by turns of wire that become free in the fusing zone making contact with each other, the resistance heating wire (11) is surrounded with a first envelope (12) of a material which cannot combine with the material of the sleeve body (2), and a second envelope (15), which consists of a material which is identical to or compatible with the material of the sleeve body (2). The cross-section of the second envelope (15) has a straight circumferential part (16) which on the one hand forms the concave inner wall of the sleeve body (2) when producing the sleeve (1), and on the other hand positions the relative location of the resistance wires with respect to the predetermined welding energy output per unit area. <IMAGE>

Each (A) is then reacted with the antibody, and absence or presence of binding detected to indicate a partial sequence of the minitopes for the particular paratope. This process can be repeated using (A) contg. additional particular positions.

Abstract: A method for measuring parameters relating to the stability of joints in a patient's body includes the steps of securing a reference portion of the joint (that portion of the joint closest to the body) to a fixed location. A three dimensional digitization of the size, shape, position and coordinate system of the two portions is performed. A soft tissue compensation procedure is performed by applying forces to the reference portion of the joint to thereby determine the amount of reference portion motion, in the soft tissue surrounding the reference portion, due to these forces. A variety of forces are applied to the relative portion of a joint, which is movable relative to the reference portion thereof, and the total motion of the reference and relative portions associated with the forces are measured. By subtracting the motion determined in the soft tissue compensation from motion as determined by applying a variety of forces, the motion of only the relative portion relative to the reference portion is determined.
