Title: Releasable plug connection between two light guides of optical cable - is formed by fusion of two monomode fibres before fixing into standard connector which ensures optical contact with end of core
Inventor: MALTZ GEORG
IPC: G02B6/28
Filed: 1992-02-01
Abstract: The connection is for optical cable (1) which comprises two optical waveguides (2,3) threaded through a split plastic tube (4) with, e.g. an aramid fibre stress-relief coating (5), in an extruded plastic sheath (6). The optical fibres are fused together at their ends (11) by gentle pressure at the m.pt. and simultaneously drawn over a predetermined length of, e.g. 15 to 30 mm. A standard plug (7,8) with stress relief and protection against fissure is fitted to the end of the approximately circular fused section after the latter has been cooled and divided approximately in the middle. USE/ADVANTAGE - E.g. for local area network computer cabling to Fibre Data Distribution Interface standard. More compact double plug connector costs no more than simple plug, and gives rise to less confusion when making connections.

IPC: B01J23/44
Filed: 1992-03-26
Abstract: A catalyst contains 0.3 to 5, in particular 0.5 to 2 % by weight palladium on an activated carbon substrate, with respect to the dryed catalyst. The catalyst is obtained by impregnating the substrate with an aqueous palladium salt solution, by precipitating the palladium and by reduction (activation). In order to produce the catalyst, an alkaline-reaction activated carbon, having in particular a pH value of at least 8, is impregnated with the palladium salt solution and the excess fluid is separated after it has reached a pH value of at least 1, in particular at least 3 and preferably at least 4. A particularly high activity and long service life, as well as a particularly simple and economical production process, are thus obtained.

Patent DE-4231548-A1 (DE)
Inventor: WELLIVER WILLIAM RUSSELL
IPC: C04B11/26
Filed: 1992-09-21
Abstract: This invention relates to an improved process for producing gypsum calcium sulfate dihydrate flakes from powdered gypsum calcium sulfate dihydrate obtained from the desulfurization of flue gas by the wet limestone process. The flakes have sufficient size and strength such that the gypsum calcium sulfate dihydrate can be handled and processed in conventional equipment commonly used by wallboard manufacturers and others in the construction industry. The intermediate calcium sulfate dihydrate from the desulfurization process is dewatered to about 5 to 12% by weight and then compressed into a thin sheet under a compaction or compression load of 4 tons force to 15 tons force per linear inch of sheet width. A linear speed of from 0.5 to 2.5 feet per second is maintained during compaction providing a compaction residence time of from about 0.2 to 1.2 seconds. An elevated temperature is maintained during the compaction process to enhance the reformation of the crystal size and shape of the gypsum calcium sulfate dihydrate. The combination of pressure and temperature on the moist gypsum calcium sulfate dihydrate alters the physical characteristics of the gypsum calcium sulfate dihydrate, thereby resulting a sheet which breaks into hard flakes on exit from the compaction zone.
