Title: Mfr. of bushings or linear guides with pockets for rolling elements - by precision moulding rings or rectangular elements and inserting balls or rollers in hemispherical or cylindrical recesses before joining together
Inventor: GIEGERICH ERWIN
IPC: B23P13/00
Filed: 1991-11-09
Abstract: Mfg. method for bushings or linear guides with pockets for rolling bearing elements, similar to bearing cages, whereby the bushing is built up from several coaxial rings or the linear guide from rectangular elements with semi-spherical or semi-cylindrical recesses in their contact surfaces, which together with the adjacent element form spherical or cylindrical pockets. Individual elements are first precision moulded; the rolling elements (balls, cylindrical rollers, needle rollers, spherical rollers) are inserted and the elements are joined together to form bushing or linear guide. Pref. the rings or rectangular elements are produced by injection moulding and bushing or linear guide is built up from two or more such elements. The pockets in adjacent elements are staggered relative to each other. The rings or linear elements are joined by socket or snap connection or by welding (ultrasonic, friction, thermal, laser) or by adhesive or by rivetting (esp. ultrasonic) or by screw fastening. USE/ADVANTAGE - Provides an economic mfr. for rolling bearing bushings and linear guides of high quality and service life.

Title: Hydrodynamically operating radial axial slide bearing - has divided radial bearing with the same or more segments than the number of axial slide faces and using its displaced lubricant to supply the axial bearing.
Inventor: DILLMANN JUERGEN
IPC: F16C17/04

Patent DE-4221259-A1 (DE)
Inventor: KAUFF PETER DIPL ING
IPC: H04N19/115
Filed: 1992-06-26
Abstract: Broadband digital color television signals to meet the standards (proposed) for future HDTV systems require data reduction for magnetic tape recording. This should also provide for intermittant cutting, fast search runs, slow motion and freeze frame with optimal picture quality. In a modular system with as many like components as possible and with the information content of the individual frames distributed on a macroblock basis, a coding of high-level precision and efficiency is carried out by orthogonal transformation and separation of the data into FLC (fixed length coding) and VLC (variable length coding), thus enabling optimal utilization of the data capacity available for each recording channel through feed-forward control based on feedback per frame pulse.

Title: Heat engine
Inventor: REITZ JOHANNES
IPC: F01C11/00
Filed: 1993-02-13
Abstract: A heat engine (10) has two hollow cylindrical sections (12, 14) which can be filled with a gaseous medium (40). In each hollow cylindrical section there is a rotating displacer (90) with a plurality of dividers (82, 84) in the area between the inner wall (85) of the hollow cylindrical sections and the displacer. Inlet areas (48) and outlet areas (44) for the gaseous medium (40) in each hollow cylindrical section (12, 14) ensure that the medium (40) can flow through the hollow cylindrical sections (12, 14) one after the other in the same direction of flow. One displacer can thereby act only as compressor (12) and the other displacer only as working rotor. The cells (44, 48) of the two hollow cylindrical sections (12, 14) communicating with the inlet area and the outlet area respectively are designed so that during the rotational movement of the displacer (90) in the hollow cylindrical sections the difference in volume between the two cells (44, 48) virtually has a value of zero. The said heat engine is characterised in that there is a combustion chamber (46) for internal combustion between the respectively communicating cells (44, 48) of the two hollow cylindrical sections (12, 14). <IMAGE>

Title: Filling pipe for a filling machine which is designed preferably for filling valve bags
Inventor: RECKERSDREES THOMAS
IPC: B65B39/04
Filed: 1993-02-24
Abstract: In the case of a valve-bag filling machine, the intention is to achieve the situation where, after the filling operation is complete, filling material does not trickle out of the filling pipe since, as a result, the weight accuracy is impaired and the surroundings of the filling machine are soiled. According to the invention, the outflow opening (13) of the filling pipe (10) is bounded by a closure ring (14) consisting of a filter material. Said closure ring (14) is enclosed by an annular chamber (15) which is subjected to a vacuum as soon as the filling operation is complete. This achieves the effect of a pneumatic closure of the filling pipe (10). The filling pipe according to the invention can be used for rotating packaging machines, series packaging machines as well as for filling machines having a downpipe. <IMAGE>
