Title: Torsional oscillation damper for power transmission system - has input side connection attached to output side connection, rotating in relation to each other
Inventor: MATSUOKA YOSHIHIRO
IPC: F16F15/167
Filed: 1993-07-06
Abstract: The metal housing (17) is connected to one of the connections on the input and output sides, extending in a peripheral direction, and contains fluid. The housing consists of several peripherally curved segments. A resin slide valve (19) is joined to the other connection and is positioned so that it can move in the housing in a peripheral direction. The slide valve consists of the same number of segments as the curved housing segments. Between the housing's inner wall and the slide valve is a gap. The slide valve's coefficient of thermal expansion is higher than the housing's and is set so that, when the fluid's operating temp. rises, the slide valve expands and narrows the gap. ADVANTAGE - Proportional damping of torsional oscillations occurs by the housing being connected to the input or output rotational element.

Title: Method for leak proofing pipe connections
Inventor: MENGEDOHT RAINER DIPL ING
IPC: E03F3/06
Filed: 1994-07-23
Abstract: The method involves the use of a head in which a small pressure cylinder (10) is mounted. The cylinder contains a winding arrangement on which a wire, or an auxiliary tube and a lining sleeve are wound. The head is positioned in the main pipe by a robot. Saddles pieces (11) are mounted either side of a gap in the cylinder. The edges (13)n of a collar piece (14) of the auxiliary tube are attached to the edges of the saddle pieces. The collar supports a ring-shaped part of the lining sleeve. The sleeve is made from a stretchable material which is impregnated with resin. Pressure is built up in the cylinder so that the collar is elastically deformed and presses against the ring-shaped part of the sleeve against the edge of the branch part. The pressure in the cylinder is increased and the sleeve, together with the auxiliary sleeve, are pushed into the branch pipe. Pressure in the auxiliary tube presses the sleeve against the branch pipe.

Patent WO-8702170-A1 (WO)
Title: Magnetic head
Inventor: REINHART KARL-FRANZ
IPC: G11B5/33
Filed: 1986-09-19
Abstract: Magnetic head (49) for reading digital magnetic information on a magnetic recording support (9), in which three or more magnetic sensors (12, 13, 14) are provided per recording track. An increase in the recording density of signals on the magnetic recording support (9) is achieved by equalization of the playback signals in the local region. The desired reduction in the half amplitude width (33) of playback signals is achieved by the interconnection of the output signals which differ in value and polarity from at least three sensors (12 to 14), which simultaneously scan the environment of a magnetic flux change in the information carrier. The distance between the sensors (12 to 14) in the recording direction (11) corresponds approximately to half of the half amplitude width (33) of the local resolution of the central sensor (12). The differing value of the output signals (32, 34, 35) occurs because of the differing geometrical dimensions of the sensors (12 to 14). The different polarity of the signal (32) of the central sensor (12) compared with the signals (34, 35) of the adjacent sensors (13, 14) can be obtained, in the case of magnetoresistive sensors by the choice of the operating points (68, 69, 70) in the regions of increases in the characteristic curve having differing signs. The equalization in this magnetic head arrangement operates irrespective of the speed at which the magnetic recording carrier (9) moves.
