Patent DE-3602565-A1 (DE)
Title: Roller press having a long-nip press roller
Inventor: MUELLNER JOSEF
IPC: D21F3/02
Filed: 1986-01-29
Abstract: A long-nip press roller has a flexible, tubular, inflatable press casing which rotates about a stationary supporting body. To generate the pressing force, the press casing can be pressed against a drivable counter-roller by means of a hydraulically actuable press shoe. The press casing designed without its own drive is driven by the counter-roller and via a felt band which runs between the counter-roller and press casing through the pressing zone. For starting, the press casing is inflated, the press shoe initially remaining non-loaded. Only after a specific minimum speed has been reached is the press shoe pressed against the press casing and the air pressure in the press casing reduced. As long as the roller press is operated only at crawling speed (which is lower than the said minimum speed), the supply of lubricating or cooling fluid into the interior of the long-nip press roller is blocked.

Title: Adjustable and lockable joint fitting, in particular for vehicle seats
Inventor: BAUER HEINZ
IPC: B60N2/22
Filed: 1986-03-17
Abstract: The adjustable and lockable rotary joint fitting is intended in particular as a joint for a seat-height or back-inclination adjusting mechanism in vehicle seats and has a first joint arm which serves as a frame (20) and in which is mounted a shaft (22) which is rotationally connected to a second joint arm (28). The adjusting is effected via a toothed adjusting wheel (32) and an actuating arm (44) with two drivers (46, 48). Arranged between the shaft (22) and the adjusting wheel (32) are two helical springs (56, 58) which bear resiliently against a receiving bush (40), are arranged so as to act in opposite directions and bear, with play on both sides, on the shaft (22) with one respective end region and in the vicinity of a stop (64) rotationally connected to the adjusting wheel (32) with the other respective end region. During a pivoting movement of the actuating arm (44), the stop (64) first strikes the helical spring which would block rotation of the shaft (22) in the same direction of rotation, releases this helical spring on continuing the pivoting movement and then transmits the further pivoting movement to the shaft (22). <IMAGE>
Patent DE-3608973-A1 (DE)
Title: Process and device for controlling the compression phase in the injection moulding of thermoplastic moulding compositions
Inventor: WIPPENBECK PETER PROF DIPL ING
IPC: B29C45/77
Filed: 1986-03-18
Abstract: In the injection moulding of thermoplastics, after the volumetric filling of the mould tool, a compression pressure is exerted over a holding time, whilst the cooling of the moulding compound simultaneously advances. This is associated with replenishment of the composition into the mould tool, which is terminated as soon as the sprue channel (feed channel) is closed (sealing). The compression state, determined by the pressure and temperature, at the point in time of sealing, determines the moulding weight, which is decisive for the dimensional accuracy of the moulding. High dimensional accuracy is obtained according to the invention in that the sealing is caused by a sprue closure element, which is actuated at a predetermined compression state of the moulding compound, in each case, and thus initiates the isochoric cooling. According to Fig. 1, the compression state is predetermined as a material-specific function of the parameters of pressure and temperature and is used by a master computer 45, with values measured at a typical point in the mould tool, for initiating the sealing. Unavoidable fluctuations in the pressure/time function and/or the temperature/time function during the cooling of the moulding composition are thus insignificant with respect to the weight constancy and the dimensional accuracy of the mouldings. <IMAGE>

Title: Process for producing crude iron by smelting of calcined pyrite and/or metallurgical dust
Inventor: MUEHLBERGER HORST DIPL PHYS DR
IPC: C21B3/04
Filed: 1986-11-27
Abstract: A process for producing crude iron by smelting calcined pyrite and/or metallurgical dust is described, in which it is the object to remove nonferrous-metallic and/or semimetallic impurity elements of the iron oxide or to separate them off and to expel them. The calcined pyrite and/or metallurgical dust compacted together with reducing carbon to give pellets or briquettes is here reduced in an unlined and water-cooled foundry shaft furnace, namely a hot-blast cupola, together with lumpy coke and limestone additions, and the resulting iron metal is carburised and fused to molten cast iron. For this purpose, the foundry shaft furnace or hot-blast cupola is operated in the region of its melting zone or in the reduction centre respectively at a temperature of from 1500 to 1800@C. The nonferrous-metallic and/or semimetallic constituents are thus vaporised and thereupon expelled upwards from the region of the melting zone or reduction centre in the direction away from the shaft furnace hearth.
