Title: Elastic hollow section forming seal - is shaped like bar or strip, and is inflated by pressurised medium
Inventor: WEISS NORBERT
IPC: F16J15/46
Filed: 1990-02-23
Abstract: The rubber or other suitable rectangular elastic hollow section (1) in the form of a bar or strip is inflated by a  pressurised medium across its lengthwise axis.

Title: Reusing glass-filled propylene scrap - by adding the scrap from separate extruder and then wood flour to stream of polypropylene in an extruder and expressing from flat sheet die
IPC: B29C48/03
Filed: 1990-05-22
Abstract: Composite materials are produced based on wood flour-filled polypropylene which contains 10-50 wt.% wood flour and 2-20 wt.% glass fibres of average length less than 2 mm; in the prodn. process the materials are mixed together and extruded in the form of flat sheeting. The glass fibres used are shavings from scrap glass mat-reinforced polypropylene. Pref. the polypropylene is first melted at 220-280 deg.C in an extruder (1) and the glass-filled polypropylene shavings are fused in a separate extruder before being fed in (3).

Title: Extruded strand diameter control - compensating for shrinkage
Inventor: SIKORA HARALD
IPC: B29C48/92
Filed: 1990-01-13
Abstract: The outside dia. of an extruded strand, esp. of a cable, is controlled by a first measurement of the dia. after the extruder and a second after the cooling section. The two readings are compared taking into consideration the time delay between them. This establishes the precise shrinkage for any necessary corrective measure. Core (10) passes the extruder (11) and the cable (12) reaches the cooling section (13) moving in the direction of arrow (14). Two units (15,16) check the o.d. The unit (17) produces signals corresp. to the cable length. A FIFO (first in-first out) data logger or shift register (30) corrects D1 to D1' and the comparator (31) compares D1' with D2. An averager (34) compensates for out-of-roundness fluctuations and the integral-action controller (33) receives a differential signal from the comparator (32). ADVANTAGE - This is simple and low-cost method of holding the cable dia. constant.
