Patent DE-3520607-A1 (DE)
Title: Gate valve
Inventor: HELMSEN WERNER DIPL ING
IPC: F16K3/314
Filed: 1985-06-08
Abstract: Gate valve with a housing in which there is a through passage, the walls of which are interrupted by a wedge-shaped gap into which a wedge-shaped slide can be moved. In the shut-off position, the wedge surfaces of the slide rest in a leak-tight manner against annular end faces of the walls of the through passage in the gap. An actuating rod is connected to the slide and is fixed against sliding in the direction of the wedge. The slide consists of two halves split in the direction of the wedge and supported on one another centrally via a universal joint, allowing movement. In their opposing faces, the two halves of the wedge-shaped slide each have a recess into which the end of the actuating rod engages positively with lateral play. The actuating rod is thus connected directly, without intermediate elements, to the halves of the wedge-shaped slide, thus eliminating complicated and costly intermediate elements. The design is correspondingly small and, as a result, small overall dimensions of the gate valve are possible. The conditions of flow are favourable. <IMAGE>

Title: Jointed connection of pipe parts, especially in the case of exhaust pipes of motor vehicles
Inventor: WINZEN WILFRIED DR ING DR
IPC: F01N13/18
Filed: 1985-07-12
Abstract: A jointed connection of pipe parts is specified, especially in the case of exhaust pipes of motor vehicles, which connection consists of at least one flexible pipe element in the form of a metal bellows or the like with connecting pieces at the ends, can move axially, laterally and in an angular manner via connecting elements which interact with the connecting pieces and via supporting pads which are interposed between them, and has an inner protective pipe for the flow path of the medium. In this case, the connecting element is jointly formed by the inner protective pipe with the insertion of the latter, in that the free end of the inner protective pipe is supported with respect to the connecting piece there via one or more supporting pads, the supporting pads being supported with respect to the connecting piece via a supporting part which is constructed as a separate structural part but can also be represented by the connecting piece itself.
Patent DE-3527991-A1 (DE)
Title: Radial shaft sealing ring
Inventor: MONDON GERALD
IPC: F16J15/3224
Filed: 1985-08-03
Abstract: The invention relates to radial shaft sealing rings by means of which a sealing location is sealed off with the same sealing intensity at all times over the entire extent of the sealing surface, even in the case of shaft eccentricity or shaft misalignment. The sealing or clamping element, which is designed, for example, as a profiled spring-loaded rubber ring, does not undergo constrained deformation in the event of radial movements of the shaft since it is not attached to the supporting housing, which is seated in the bore. To fix it axially in position, the spring-loaded rubber ring is, on the contrary, guided in a sealed manner and with the ability to slide radially between walls of the supporting housing. <IMAGE>
Patent DE-3528876-A1 (DE)
Title: Guiding wire
Inventor: SCHUBERT WERNER DR MED
IPC: A61M23/00
Filed: 1985-08-12
Abstract: In small-caliber guiding wires having a diameter of less than 1 mm it is impossible to expose a nozzle body to fluid at its front. However, in combination with specially designed catheters its movements can be improved, in particular, in a narrowed pathway of the body. For this purpose, the rear part of the catheter is to be sealed with a stocking-like membrane over the guiding wire extending axially therein. The front of such single-lumen catheters must be provided with a nozzle head having at least one nozzle directed forward, so that fluid jets reach the space located in front of the catheter simultaneously with the excitation of a floating element of the front nozzle in order to impart oscillations and at the same time reach the space in which the front part of the guiding wire is located, so that the guiding wire can be advanced better and farther there, with displacement of the wall of narrowed vessels of other pathways. It is even possible to couple this principle with the use of a balloon at the front of a double-lumen catheter if a coaxial double tube for a catheter is used in which the guiding wire can be pushed through or retracted longitudinally and axially without any rear connection, whilst fluid is passed to the balloon/balloons via simple transverse perforations in the catheter wall through the cylindrical lumen of the catheter which is present on the outside thereof and is also closed at the back. Additional oscillations are ... by ... Original abstract incomplete.

Title: Circuit arrangement for power supply
Inventor: STUEDEMANN BERND ING GRAD
IPC: H02M3/335
Filed: 1985-10-31
Abstract: In the case of a circuit arrangement for power supply, in the case of which a switched-mode power supply whose primary is pulsed is supplied with an input DC voltage which is produced by rectification of an AC voltage, and produces at least one output DC voltage whose magnitude can be regulated with the aid of a control loop, means are provided for cutting off an AC voltage which is superimposed on the input DC voltage, and for supplying the AC voltage to the control loop. As a result of this, it is possible to reduce the ripple voltage on the output DC voltage without disadvantageously increasing the size of the charging capacitor and without critically increasing the control gain. The circuit arrangement can be used advantageously in visual display units.

Title: Fluidised-bed furnace for waste in lumps
Inventor: NIJS GUIDO DIPL ING
IPC: F23G5/30
Filed: 1986-03-06
Abstract: Fluidised-bed furnace for waste in lumps, in which, in an essentially cylindrical casing, a concentric pipe is submerged into the fluidised bed, the actual furnace space being arranged inside this concentric inner pipe or in the annular gap between the concentric pipe and the outer casing. In the first case, the fuel is blown tangentially into the annular gap between the concentric central-pipe furnace space and the outer casing and, distributed uniformly over the entire circumference, pressed from outside inwards in an annular manner into the fluidised bed under slight overpressure. In the second case, the material to be combusted is blown in through the concentrically arranged central pipe and pressed into the fluidised bed from inside outwards under slight overpressure, the fluidised-bed furnace space being situated outside this central pipe.   In both cases, the fuel is introduced into the fluidised bed below the fluidised-bed surface and distributed uniformly to all sides even in the case of relatively large furnace diameters. <IMAGE>

Title: Method and device for interfering with electromagnetic radiation
Inventor: KOELBL WILHELM DIPL ING
IPC: G01S7/495
Filed: 1986-03-22
Abstract: To interfere with the laser rangefinders of hostile weapons carriers, it is proposed to generate an interfering radiation at the vehicle or military object to be protected, which radiation is either delayed or completely uncorrelated with respect to an incoming laser ranging pulse. In both cases, the laser interference pulse arriving at the hostile laser rangefinder creates a false transit time information with respect to the ranging pulse and thus leads to a wrong range value. <IMAGE>

Title: Circuit arrangement for inductive three-phase loads, especially three-phase drives
Inventor: BEZOLD KARL-HEINZ
IPC: H02M7/521
Filed: 1986-04-08
Abstract: The invention relates to a circuit arrangement for inductive three-phase loads, especially three-phase drives, which is operated via an invertor in a three-phase bridge circuit and via an upstream DC intermediate circuit, the supply being effected via a DC controller from a DC network with a network capacitor. In order to improve the recovery and in order to reduce the voltage load on the components such as valves, capacitors and motor it is proposed to connect a rectifier bridge (15) to the three-phase connections of the invertor (WR), which bridge feeds back to the network capacitor (CN) via a parallel-connected buffer store (CKap), it being possible to set the mean voltage value on the buffer store (CKap) via short-circuiting DC controllers. Further advantages are a considerable reduction in the weight and the volume of the capacitors required and a reduced adjustable voltage load on the elements, with an extended frequency adjustment range of the valves. <IMAGE>

Patent DE-3636793-A1 (DE)
Title: Use of lipopolysaccharides and/or their derivatives in combination with immunoglobulin preparations for antiinfectious treatment
Inventor: KAUFMANN ROLF DR
IPC: A61K39/395
Filed: 1986-10-29
Abstract: Lipopolysaccharides which, in high doses, lead to irreversible states of shock also show, when used correctly, therapeutically utilisable effects. Immunoglobulin products have long been used for warding off infections. Animal experiments have shown, however, that the two groups of substances alone do not provide adequate protection against bacteria such as Pseudomonas aeruginosa. In contrast to this, combined use of lipopolysaccharides (LPS) or of lipid A or the corresponding derivatives with immunoglobulins leads to good results in the treatment of infections. Particularly good effects are achieved when an antibiotic is also used as third component.
