Patent DE-3638533-C1 (DE)
Title: Cylindrical running surfaces
Inventor: GREINER PETER
IPC: F02B75/02
Filed: 1986-11-11
Granted: 1988-01-14
Abstract: The invention relates to cylindrical running surfaces, especially for engine blocks, in which the surfaces in the form of liners with thermal expansion properties differing from the block material are held elastically clamped in the block. In order to take account of these differing expansion properties of the material constituents involved and to prevent the liner from losing its holding contact with the engine block when correspondingly heated, an inherently prestressed retaining liner (3), of a material with the same or approximately the same coefficient of expansion as the block material, is arranged between the liner (1) with a lower coefficient of expansion than the block material and the block (2). This retaining liner (3) is provided with at least two axially parallel expansion joints (4), open only towards the liner (1) and extending over the entire length of the liner, which are bridged by joint surrounds (6). <IMAGE>
Patent DE-3733739-C1 (DE)
Inventor: WERMUTH JUERGEN ING
IPC: H03M1/18
Filed: 1987-10-06
Granted: 1989-04-27
Abstract: To permit analog-to-digital conversion of signals which have a larger volume range than an analog-to-digital converter 2, Fig 1, would actually permit an analog compressor 1 is connected ahead of the analog-to-digital converter 2 and a digital expander 3 is connected directly subsequent to it. The analog compressor, 1, comprises two oppositely level-dependent amplifiers 20, 40, Fig 2. The first amplifier 20 reduces the volume range by 40%. At low frequencies of the input signal the second amplifier 40 receives no control signal from an adder 90. At high frequencies of the input signal the second amplifier 40 is controlled to expand the range of the signals from amplifier 20 by weakening low amplitude signals. <IMAGE>

Title: Shut-off device for a pipe-tapping fitting
IPC: B23B41/08
Filed: 1988-08-16
Granted: 1989-09-28
Abstract: The pipe-tapping fitting 3 comprises a vertical connection piece 4, into which an insert cylinder 7 can be screwed. A piston 11 is provided in the insert cylinder 7. The piston 11 forms an integral part of a piston rod 12, on the other end 14 of which is provided a sealing body 15 which cooperates with a sealing seat 16 on the circumference of the pipe-connecting bore 17. The piston space of the insert cylinder 7 is connected to a shut-off valve 25 via a flexible conduit 24. The shut-off valve 25 can be connected to a water pump 26. The piston 11 can be displaced into the open position by the pressure of the fluid in the supply conduit 1 and into the closing position by the water pump 26. The piston can also be designed as a plunger. In this case, the sealing body is a one-piece integral part of the plunger. The bore in the insert cylinder is then designed without projection. <IMAGE>

Title: Method of connecting the ends of toothed belts
Inventor: BARTELT DIETRICH
IPC: F16G3/10
Filed: 1993-12-01
Granted: 1995-05-11
Abstract: A method of connecting the ends of toothed belts, which are provided with tension-strand inserts and in which the toothed-belt ends to be connected are placed one on top of the other and are split up by a common cut into sections interlocking in an accurately fitting manner, is to be provided in such a way that it is possible, despite the severing of the tension-strand inserts, to form the joint in such a way that its force transmission comes as close as possible to that of the rest of the belt. To this end, provision is made for a common straight cut to be made for preparing the connection of the toothed-belt ends. The straight cut is inclined at an angle to the longitudinal extent of the toothed belt and is directed through the ends of the toothed belt placed one on top of the other, the inclination being selected in such a way that the cutting point of the individual tension-strand inserts is offset by at least the width of a parting seam from the respectively adjacent cutting point in the longitudinal direction of the toothed belt while maintaining the width of the parting seam, so that, with the filling of the elastomeric material required, in each case only a single severed tension-strand insert is located in each cross-sectional plane of the cutting area running perpendicularly to the longitudinal direction of the toothed belt. <IMAGE>
