Patent DE-3365425-D1 (DE)
Title: Active impedance transformer assisted line feed circuit
Inventor: ROSENBAUM STANLEY DANIEL
IPC: H04M19/00
Filed: 1983-05-11
Granted: 1986-09-25
Abstract: A transformer assisted active impedance line circuit includes a transformer of reduced size as compared to both conventional and d.c. flux reduced transformer line circuits. The transformer has tip and ring primary windings consisting of equal turns and a secondary winding. Tip and ring amplifier circuits each have an output coupled to tip and ring terminals via tip and ring feed resistors which are connected in series with the tip and ring primary windings respectively. A direct current flow, out of the output of one of the amplifier circuits and into the output of the other of the amplifier circuits via two wire communication line connected to the tip and ring terminals, is of an aiding flux-generating effect in the transformer. The secondary winding is terminated by an impedance and provides a.c. signals to which the tip and ring amplifier circuits are responsive to reduce a.c. voice signal current components in the communication line.

Title: Gas flushing plug for metallurgical vessels
Inventor: HOFFGEN HANS DIPL ING
IPC: C21C7/072
Filed: 1984-10-15
Granted: 1987-06-04
Abstract: A gas bubble brick for metallurgical vessels consists of a porous, gas-permeable shaped brick (2) made of refractory material, a gas-tight partial encasing surrounding the latter, which encasing is welded together from a metal jacket (4) extending around the lateral circumferential area of the shaped brick and a metal cover (6) covering the outer face of the shaped brick, a gas supply pipe (10) which is welded to the rim of a central gas inlet orifice (8) of the metal cover (6), as well as a break-through safeguard in the area of the gas supply pipe. In order to prevent closure of the gas bubble brick in the gas outlet area and in order thereby to ensure purge readiness, a constricted cross-section (12) is provided inside the gas supply pipe (10) at a distance from the gas inlet orifice (8) of the metal cover (6), there being provided in the pipe section between the metal cover and the constricted cross-section a closure body (17), which is movable at least in the axial direction of the gas supply pipe and is, for example, a copper ball or the like, the cross-section of which is smaller than the inside diameter of the gas supply pipe (10) and greater than the constricted cross-section (12). The closure body (17), together with the constricted cross-section (12), thereby forms a non-return valve, which prevents a pressure drop occurring in the gas bubble brick after switching off the gas supply.

Abstract: A microwave sterilizer for sterilizing a connector or coupling that interconnects a first conduit from a source of liquid to be infused into a living body to a second conduit implanted in the body. The apparatus of the invention comprises a housing having first and second members forming a guided wave structure adapted to be removably closed around the coupling or connector and further including first and second clamping means. The clamping means are adapted to clamp respective conduits and are operable to isolate a charge of the liquid within the connector. A microwave source is used to generate energy which in turn is coupled to the guided wave structure to cause heating of the liquid charge to a temperature level to cause sterilization so as to destroy substantially all form of bacteria therein. After a predetermined heating sequence, the apparatus is released and the bag side clamping means is first released so as to pass the sterilized charge of liquid into the source or bag.

Abstract: A device for establishing a current-conducting connection between a strip-shaped conducting member and one or more wire-like conductors has a reinforced frame with two mutually inclined internal surfaces which make an angle of 30 degrees. The conducting member is placed against one of the internal surfaces and the conductor or conductors are placed adjacent the conducting member in the interior of the frame. A screw whose axis halves the angle between the two internal surfaces meshes with the frame and carries a clamping element which has an elongated slot for the shank of the screw and which slides along the other internal surface of the frame in response to rotation of the screw to move the clamping element in the direction of convergence of the internal surfaces whereby the clamping element bears against the conductor or conductors and urges them against the conducting member so that the latter is biased against the one internal surface. The slot enables the clamping element to move transversely of the axis of the screw, for example, to become disengaged from the conductor or conductors when the screw is rotated to move the clamping element counter to the direction of convergence of the internal surfaces. The angle between the axis or axes of the conductor or conductors and the axis of the screw is approximately or exactly 15 degrees.

Abstract: The device has a hub body (4) which is screwed into the end face of the knife shaft (1) and on which there is seated an annular piston (8) which acts axially on the knives (20). A piston (6) is screwed into the hub body (4). A drive part (31) having an external hexagon (32) designed to take a spanner is connected via a torque-limiting system (41) to the piston (6). During assembly, the hub body (4) is screwed in until the annular piston (8) rests on the knives (20). When the drive part (31) rotates, the piston (6) displaces oil into the cylinder chamber (10) of the annular piston (8) so that the knives (20) are securely clamped. If a predetermined torque is exceeded, the drive part (31) continues to rotate with respect to the piston (6) by means of a torque-limiting system (41). The optimum contact-pressure force of the annular piston (8) can consequently be precisely adhered to during assembly. <IMAGE>
