IPC: C07C51/58
Filed: 1990-01-12
Abstract: Abstract of the Disclosure:          HOE 89/F 009 A process for the dimerization of hexafluoropropene oxide A process for the preparation of the dimer of hexafluoro-propene oxide (HFPO), in which the HFPO is dimerized in an aprotic polar solvent in the presence of a catalyst mixture, is described. The catalyst mixture is composed of a metal salt of the elements of the 1st transition metal series of the periodic table and of a tertiary diamine. By bringing in a molar ratio of metal salt to tertiary diamine in the range from 2:1 to 1:2, in part-icular 1:1, the selectivity for the dimeric compound is greatest, with high yields of the dimer being obtained.

Patent CA-2008048-A1 (CA)
IPC: B65H39/11
Filed: 1990-01-18
Abstract: A paper positioning device having a paper positioning member which is pivotable in abutment against one edge of a paper sheet loaded on a receptacle for moving the paper sheet to a positioning position for thereby positioning the paper sheet. By a simple mechanism and control, the movement of the paper positioning member is slowed down at the positioning position and accelerated until the positioning member reachines it. The paper positioning member performs a pivoting movement twice while a drive shaft associated therewith performs a reciprocating movement once. The device is, therefore, not only durable but also positions paper sheets efficiently and positively without damaging the paper sheets.

Title: Refractory assembly including inner and outer refractory members with interference shrink fit therebetween and method of formation thereof
Inventor: SCHWARZ HANS G
IPC: F16B4/00
Filed: 1990-04-05
Abstract: A refractory assembly includes a refractory outer member (1) having therein an opening (2) defined by an inner surface and a refractory inner member (3) having an outer surface. The dimension of the outer surface of the inner member is greater than the dimension of the inner surface of the outer member by an amount of from 0.05 to 0.15 mm. The outer member is heated to at least 1000°C to thereby increase the dimension of the inner surface.

Abstract: METHOD AND APPARATUS FOR GENERATING MICROBUBBLES IN FROTH FLOTATION MINERAL CONCENTRATION SYSTEMS     ABSTRACT OF THE DISCLOSURE     A method and apparatus for generating microbubbles in a flowing liquid stream for use in a froth flotation system.  The system utilizes a microbubble generator having a tubular housing with an inlet end and an outlet end. Located coaxially within the housing is an inner member with an elongated, tapered, exterior surface.  A porous tubular sleeve is mounted between the housing and the inner member coaxially therewith to define with the cylindrical-interior surface of the housing an elongated air chamber of annular cross section.   The porous sleeve has a cylindrical inner surface that defines with the exterior surface of the inner member an elongated liquid flow chamber of thin,  annular cross section.  An aqueous liquid is supplied to the liquid flow chamber at a relatively high flow rate and air under pressure is supplied to the air chamber so that air is forced radially inwardly through the porous sleeve to be diffused in the form of microbubbles in the flowing stream.

Filed: 1990-08-02
Abstract: MULTI-FIBER ALIGNMENT PACKAGE FOR     OPTOELECTRONIC COMPONENTS            ABSTRACT      A localized cooling method allows the sequential alignment and soldering of one optical fiber at a time to a semiconductor package, while previously aligned and soldered optical fibers are held fixed.  This method utilizes the mechanical property of a sharp melting point eutectic alloy solder or a pure metal solder for the fiber connections  and is effective  for multi-fiber opto-electronic  packages  demanding  stability  and  high precision.  A package design for optoelectronic components requiring multi-fiber alignment incorporates this feature of localized cooling internally.  The localized cooling method and the novel package utilizing this method internally make it possible to eliminate the tilted angle optical fiber alignment problem by mounting tilted facet optical amplifier components at a predetermined offset angle.
