Title: Prodn of ski with sole, core and top section - by hot pressing together at suitable pressure top surface section, bottom sole, edges and prefabricated core wrapped in prepregs
Inventor: ROYER FRANZ DIPL ING
IPC: A63C5/12
Filed: 1992-10-06
Abstract: A ski is produced with a surface tray section, a sole and a prefabricated core; in the process the core and reinforcements are wrapped round with prepreg material, and they are hot pressed together with the edges, the sole and surface section at temps. which cause the resin to flow and cure.

Title: Yarn sizing plant - has initial treatment for removal of oil from synthetic yarns
Inventor: KLAUKE H-J
IPC: D06B23/06
Filed: 1992-11-11
Abstract: A process to size warp threads by taking them through an immersion bath, a mangle and then a drying range. A prior process is to take the warp through an immersion bath of water. Typically, the installation has a water immersion bath (24) with immersion roller (26) and mangle (28). The water is at room temperature and contains a chemical additive. The fluid can be filtered to remove unwanted material. The sizing rollers (12) carry the warp threads under and over to ensure the size is applied thoroughly, and this is squeezed out (16) before the threads are separated along the table (18). The thread is then dried by the usual apparatus (20). ADVANTAGE - The water immersion may have an addition of chemical to remove the oil from a synthetic yarn, the subsequent size treatment is then more effective, and the warp can be handled in a customary manner.
Patent DE-4239022-A1 (DE)
Title: Sepn. of hydrogen@ and gas of higher b.pt. esp. ammonia from gas mixt. - esp. purge gas from ammonia synthesis by partial ammonia condensation near triple point and hydrogen sepn. by permeation without adsorption
Inventor: VOGEL REINHART DR
IPC: B01D5/00
Filed: 1992-11-19
Abstract: In sepn. of H2 and also components (I) of higher b.pt. from a gas mixt. (II), esp. NH3 and H2 from the purge gas (IIA) from NH3 synthesis, NH3 is sepd. by partial condensation at a final temp. (Tf) near its triple point. The novelty is that, after partial condensation of NH3 and without intermediate adsorption, H2 is sepd. by permeation at ambient temp. or in the region of Tf and the cold deficit is balanced by expansion of the H2-depleted fraction (III). Permeation is carried out near Tf and the H2, expanded (III) and NH3 are warmed to nearly the inlet temp. (Ti) of (IIA) with a countercurrent (IIA) stream. Alternatively, (IIA) freed from NH3 and condensed NH3 are warmed to nearly Ti in the same way, most of the H2 is sepd. by permeation and (III) is recooled to Tf, expanded and rewarmed to nearly Ti with a countercurrent (IIA) stream. Permeation is carried out in one or more stages. In an example, NH3 was sepd. from (IIA) in appts. with permeators in the cold box. No details of the operating conditions are given.

Abstract: In this bush conveyor chain, the cylindrical lubricating surface (12) between the bush (20) and the roller (10) is continued on each side by a lateral lubricating surface (13). This is bounded by an end face of the roller and by an upper leg of a cover (14) pressed firmly on the bush.

A projection on the bush receives an elastic sealing ring (16) under prestress, the elastic sealing ring (16) having a lip bearing elastically against the cover. By means of this arrangement, the escape of oil is prevented. What is obtained is virtually a combination of sliding lubrication and labyrinth lubrication. <IMAGE>

Title: Method and device for reducing the torque acting on the drive shaft of rotating electric motors in the starting phase
Inventor: NITZSCHMANN BERND DIPL PHYS
IPC: H02K7/118
Filed: 1993-06-17
Abstract: A mechanical spring is used between the shaft element 4 and the shaft element 5 in order to convert mechanical energy into torsional energy, in order to delay the torque which acts on the driveshaft of electric motors in the starting phase.
