Patent DE-3231904-A1 (DE)
Title: Sealing ring
Inventor: RUSTIGE HAYNO DIPL ING
IPC: F16J15/3216
Filed: 1982-08-27
Abstract: The sealing ring comprises two rings (11, 12) of rigid material movable radially relative to one another and in contact with one another and also comprises a shell (13) of flexible sealing material surrounding the said rings. Sealing lips (17, 18) are formed on the inside of the shell. The shell (13) forms a bellows-like region (14) which forms an interspace (15) between the rings (11, 12) to allow their radial displacement. The interspace can be filled with a very soft, compressible material. With this design, it is ensured that the sealing ring can adapt spatially to a shift in the part to be sealed off without the risk of damage. <IMAGE>

Title: Digital phase-locked loop for synchronisation on reception of binary signals
Inventor: POPESCU ION DIPL ING
IPC: H04L7/033
Filed: 1982-09-17
Abstract: On the basis of known DPLL circuits (Digital Phase-locked loop), comprising a cycle counter (Z), a phase detector (ECPD), a forward/backward counter (VRZ) and a control circuit (I/D) connected in front of the cycle counter (Z) for insertion or extraction of one of the clock pulses for the cycle counter (Z) so that the latter is incremented in accelerated or delayed fashion and a phase correction thereby effected, the direct evaluation of binary data signals with varying frequencies is possible due to an additional bistable trigger circuit (BK) and a novel combination of the alternating input and output signals (DAT and SYN-T) to control the forward/backward counter (VRZ) so that, using simple means, binary data signals with different coding can be directly evaluated.

Title: Screen printing apparatus for printing round bodies on their outer surface
Inventor: FUCHS GERHARD
IPC: B41F15/30
Filed: 1982-12-09
Abstract: The body (10) to be printed is clamped at its two end faces (14) between two clamping jaws (52) which are mounted on a support (44) so as to be rotatable about an axis (A) of rotation. The support (44) can be tilted back and forth about a horizontal tilting axis (C), running with spacing transversely to the axis (A) of rotation, between a transfer position, in which the axis (A) of rotation is vertical, and a printing position in which the axis (A) of rotation is horizontal. In the printing position, the clamping jaws (52), together with the body (10) clamped between them, can be pressed from below by means of a lifting drive (62) against a horizontal screen (80), on which the outer surface (12) of the body (10) rolls off while the screen (80) executes a straight-line movement in its plane. Flat, disc-shaped bodies (10) with a cross-section which is not precisely circular, in particular cheese rounds, can thus be printed all around their outer surface (12). <IMAGE>

Patent DE-3328137-A1 (DE)
Title: Vacuum-tube connection
Inventor: LINNEMANN FRIEDRICH
IPC: F16L23/04
Filed: 1983-08-04
Abstract: The vacuum-tube connection has a sealing ring between two small flanges over which oblique surfaces of a clamping ring engage, which clamping ring has a closure which can be released and readjusted. The clamping ring has a U-shaped end part and, parallel thereto, a U-shaped end piece. Both the U-shaped end part and the U-shaped end piece have a lateral wall and two free insertion walls, which press obliquely away therefrom, for the small flanges. A screw thread is formed integrally in the material in the lateral wall of the U-shaped end part. A through-hole is located coaxially with respect to the screw thread in the lateral wall of the U-shaped end piece. A shank of a closing screw passes through the through-hole in the end piece and engages with a threaded part into the screw thread of the end part. A head of the closing screw, which can be displaced axially by rotation, rests on the outer surface of the lateral wall of the end piece, so that the end part and the end piece of the clamping ring are braced in the direction counter to one another, for a vacuum-tight closure of the tube connection.

Title: Cooling device for drive axles
Inventor: KALVERSBERG MANFRED
IPC: F16H57/04
Filed: 1983-08-30
Abstract: A device is proposed for the cooling of a drive axle having an axle transmission of a motor vehicle driven by a drive engine. In order to provide for efficient cooling of the drive axle, especially in the case in which the vehicle is operated at very high speeds of travel, the axle transmission housing (2) is to be enclosed by a cooling jacket (6) connected to a coolant circuit.
