Title: Preparation of polyorganosiloxanes with controlled low levels of hydroxy substitution
Inventor: HANSEN SIDNEY A
IPC: C08G77/06
Filed: 1991-10-01
Abstract: PREPARATION OF POLYORGANOSILOXANES WITH CONTROLLED     LOW-LEVELS OF HYDROXY SUBSTITUTION                       ABSTRACT           The described process uses aqueous hydrogen chloride as a catalyst to effect the condensation of chloride and hydroxy end-substituted polyorganosiloxanes, in the presence of triorganosilyl endblocker to control chain length.  The inventors have discovered that within a range of about 10 to 30 percent aqueous solution of hydrogen chloride, it is possible to produce polyorganosiloxanes with low levels of chloride and hydroxy substitution.  Furthermore, it has been found that within this hydrogen chloride range, temperature and hydrogen chloride concentration can be controlled to produce polyorganosiloxane polymers with a reproducible and predictable level of hydroxy substitution.

Title: Conveyor belt and method for its manufacture
Inventor: MURAOKA TOMONORI
IPC: B32B37/06
Filed: 1992-05-07
Abstract: ABSTRACT            Conveyor belt and method for the manufacture thereof.            A conveyor belt (1) is described, which has a support fabric (2), whichis provided with at least one thermoplastic material coating (3) and is characterized in that onto its cutting edges (4) is welded a thermo-plastic, strand-like profile material, preferably a round cord (5) so as to constitute an edge protection.  Due to the fact that the strand-like profile material (round cord 5) has a lower melting point than the thermoplastic material of the coating (3), during welding, substantially no deformation occurs in the coating (3), even in the vicinity of the contact faces, whereas the profile material having a lower meltingpoint is deformed and adapts to the shape of the cutting edge (4) of the conve-yor belt (1) and covers the same.  The inventive method makes it possible to economically provide individual endless and finite conveyor belts with an edge protection when this proves necessary (cf. fig. 1).

Title: Cyclone separator system
Inventor: KALEN BODO
IPC: B04C5/28
Filed: 1992-12-22
Abstract: CYCLONE SEPARATOR SYSTEM            ABSTRACT OF THE INVENTION     An improved cyclone separator and method of construction are disclosed.  Such cyclone separators are employed for separating particulates from hot gas entering the separator barrel through an axially disposed slot in its periphery.  An improvement in efficiency and recovery of very small particulates is achieved by making the slot very narrow so that the particulates enter the barrel very near its inner surface, thus having less distance to travel under centrifugal force in order to reach said inner surface.  In accomplishing this objective, however, it has been discovered that, for the particular inlet gas velocity selected, the structure under certain design conditions will act as a cavity resonator with the characteristic frequencies of the cavity matching the frequency of the incoming gas as it rotates in the barrel, thus causing the structure to function as a resonator thereby destroying the efficiency or, in extreme cases, having catastrophic results (in the mathematical sense).  The application explains how this hazard can be avoided.  The separator unit is provided with a novel converging inlet to enhance separation efficiency, and a method is provided for increasing bypass of particulate past the separator units without adversely affecting the operation thereof.
