Title: Pistons for force transmission by means of steam, liquids, gases, air or gas/air mixtures
IPC: F16D55/00
Filed: 1987-04-24
Abstract: Pistons for force transmission by means of steam, liquids, gases, air or gas/air mixtures, inter alia vehicle brake pistons, which are manufactured from austenitic materials based on alloys of chromium, nickel and iron plus additives and, by the nature of these materials, have relatively low thermal conductivity and fall into the category of rust- and acid-resistant steels according to the relevant DIN standard, the new feature resulting from this composition being that, faced with the excess frictional heat which arises in the case of prolonged braking and high brake pressures, there is a reduction in the temperature in the axial direction as far as the opposite end due to the lower thermal conductivity of the pistons, i.e. the action of heat on the brake fluid is thereby reduced to an acceptable level and, as a result, the brake fluid remains functional, without vapour formation, and that pistons made of such materials are resistant to environmental effects of the weather encountered in practice and to aggressive chemical attack by the brake fluids. An optimum improvement in functional reliability in combination with a longer service life is achieved in comparison with pistons produced hitherto from ferritic steel.

Patent DE-3743364-A1 (DE)
Inventor: FISCHER ARTUR PROF DR
IPC: E21B10/58
Filed: 1987-12-21
Abstract: To produce drilled holes with an undercut, drills are known which have lateral cutting edges projecting at the drill head. The lateral cutting edges are formed from carbide drill tips. When producing the drilled hole, the drill can wander laterally as a result of poor centring, which makes it more difficult to insert an expanding plug. The drill has a drill head which is enlarged in diameter relative to the shank and on which the drill tips with their lateral cutting edges only project slightly. The drill head brings about a good centring effect during the drilling operation, as a result of which straight drilled holes can be produced. <IMAGE>

Patent DE-3817169-A1 (DE)
Title: Method and device for correcting acceleration-induced errors in angular position measurements
Inventor: FISCHER MANFRED
IPC: G01S3/786
Filed: 1988-05-20
Abstract: In a method for correcting acceleration-induced errors in angular position measurements which occur as a consequence of large rotating masses in observation systems, in particular in the case of track-following systems, the variation in intensity of the electromagnetic radiation emanating from a radiation source is detected during the rotary movement of the rotating component in a laterally resolving recording unit for this arrangement. One of the two components of the optical system is held fixed in position, and the other on the moving component. By recording a reference curve at a low angular velocity and a measurement curve for accelerated movement, deviation is determined between the desired and actual values of the angle of rotation with the aid of the displacement of the signal variation measured in the process.

Title: Method for synchronising a code word with a received spread-spectrum signal
Inventor: LECHLER SIEGFRIED ING GRAD
IPC: H04B1/707
Filed: 1988-07-29
Abstract: In this method, in which a search process or a tracking control is in each case activated in dependence on whether there is a synchronisation of the code word with the received spread-spectrum signal, the code word being generated repeatedly in in each case several different phase angles, and having the different phase angles, is in each case mixed with the received signal and wherein, furthermore, phase discontinuities of several bit periods occur between the repeatedly generated code words during the search process, the signals produced by mixing the code words with different phase angles with the received signal are added after in each case band-pass filtering and envelope demodulation. The resultant aggregate signal is supplied to a threshold circuit. After this threshold circuit has operated, the search process is continued in smaller steps and a selected one of the mutually phase-shifted code words is mixed with the received signal. The result of the mixing ends the search process when a predetermined threshold is exceeded.

Title: Clamping-ring tube (pipe) connection for metallic tubes
Inventor: HACKFORTH BERNHARD
IPC: B21D39/04
Filed: 1988-11-03
Abstract: In order to produce such a tube connection, one of the tubes (1 and 2) to be connected contains a tube end (3) which is widened in a cup-like manner and in which the tube end (4) of the other tube (1 or 2) is located in a positively locking manner. Before the two tube ends (3, 4) are plugged together, a metallic clamping ring (5), whose internal diameter is smaller than the external diameter of the tube end (4), is plugged onto the tube end (3). Thereafter, the clamping ring (5) is pressed onto the tube end (4) with the aid of a suitable assembly tool. This effects a radial compression of the interengaging tube ends (3, 4) and, at the same time, a radial widening of the clamping ring (5) in the elastic region. What matters here is that the clamping ring (5), in the assembly position, effects a bracing of the interengaging tube ends (3, 4) over as large an axial length as possible. This is achieved in that the outer casing of the clamping ring (5) exhibits an encircling constriction (10) in the central portion between the relatively short, essentially cylindrical end portions (11, 12). <IMAGE>
