Title: Tape take-up arrangement unwinding e.g. thermal printer ribbon - has friction brake controlled by spool dia. sensor
Inventor: AL-KHATIB MOHAMED DR RER NAT
IPC: B65H77/00
Filed: 1989-07-10
Abstract: An arrangement for unwinding tape from spools has a spool body (1), a spool dia.

Patent DE-3923850-A1 (DE)
Inventor: HENSELER KLAUS
IPC: B05C11/02
Filed: 1989-07-19
Abstract: A roller squeegee consists of two different annular plates 2 which are clamped tightly on a cylindrical support rod 3 or fastened in some other way. In this arrangement, annular plates 2 of a smaller diameter and made of elastic material alternate with annular plates of a larger diameter made of very hard-wearing material, in particular made of ceramic. The difference in the outer diameters results in a halving of the groove depth of the circumferential grooves, of the roller squeegee, formed between the different annular plates.

Title: Nozzle with rotating nozzle head - has speed of rotation limited by brake with mechanism to adjust brake force
Inventor: FALCH ACHIM
IPC: B05B3/06
Filed: 1989-07-31
Abstract: The rotating nozzle has a nozzle head (12) which can rotate about the nozzle body. The nozzle head (12) has one or more nozzles (20) each of which has its axis (22) inclined to the axis (14) of the nozzle body. The obliquity of the nozzles is such that the reaction force generated by each nozzle has a tangential component which causes the nozzle head (12) to rotate. The speed of rotation of the nozzle head is limited by a brake consisting of spring-loaded balls (26) mounted in a housing so that the balls (26) are pressed against the end face of the nozzle head. The brake pressure can be adjusted by means of a screw cap (28). USE - Rotating nozzles.
Patent DE-3926934-A1 (DE)
Inventor: HUERTER WILLIBALD DIPL PHYS
IPC: A61N5/04
Filed: 1989-08-16
Abstract: The antenna system of the invention is insulated on the outside and when inserted in a dissipative medium has a fixed complex resistance. When the antenna is supplied with HF energy through a coaxial cable, only that area of the medium immediately round the antenna is heated. The area surrounding the insulated HF feed line is not heated, or such heating is negligible, since, owing to the fixed complex resistance of the antenna in the medium, any return of energy along the feed line is prevented. The antenna system of the invention is suitable for use in the tumour-therapy field as a hyperthermic microwave applicator for limited local heating of the cancerous tissue.

Title: Safety belt for motor vehicle - has spiral spring to tighten belt through epicyclic gear drive
Inventor: MAERTZ JOSEF
IPC: B60R22/44
Filed: 1989-12-06
Abstract: The safety belt for an occupant of a motor vehicle is wound onto a drum which is driven from the internally toothed gear (11) of an epicyclic gear train. This internally toothed gear (11) is normally driven by an auxiliary spiral spring which applies a min. tension to the safety belt. The belt is tightened by winding up the drum, on which the belt is wound, by rotating the internally toothed gear (11) by a planet gear (9) which is driven by the main spiral spring (6). The planet pinion (9) is normally prevented from rotating by being held in engagement with the sun gear (10). In the event of a high rate of deceleration the planet pinion is disengaged from the sun wheel (10) and it is rotated by the main spiral spring (6) so that it drives the internally toothed gear (11). USE - Motor vehicle safety belts.
