Abstract: CONTACT STABILIZATION COATING MATERIAL FOR        ELECTRICAL CONTACT SURFACES            ABSTRACT OF THE DISCLOSURE:            A  contact  stabilization material  is  provided,  which comprises    a   co-polymer   or   block   polymer    of polyoxypropylene  together  with polyoxyethylene,  or  a plurality of block polymers of polyoxypropylene together with polyoxyethylene. The contact stabilization material enhances the flow of electric current between contacting surfaces,  in both   high   current  and   low   current applications,  and  at frequencies ranging from DC up to ultra high radio frequencies,  by enhancing conductivity between  the  contact surfaces.  The material  does  not exhibit any tendency to "varnish" over a period of time, and  as  may  be catalysed by the  presence  of  various metals at the contact surfaces.

Abstract: Abstract 3-hydroxybutyrate polymers High molecular weight copolymers containing 3-hydroxybutyrate residues, i.e. units of the formaula -O.CH(CH3).CH2.CO-and up to 50 mole % of residues of other hydroxy acids, viz units of the formula -0.CR1R2.(CR3R4)n.CO-where n is 0 or an integer and, if n = 1 and R3, H3, and R4 = H,R1 is not methyl.          The copolymers are made microbiologically:  for part of the cultivation the micro-organism is under conditions such that polymer is accumulated, e.g. by limitation of a nutrient, e.g. nitrogen source, required for growth but not polyester accumulation.          For at least part of this period of polymer accumation the substrate is an acid or a derivative thereof that gives the comonomer units.          Propionic acid, which gives polymers where n = 1, R2=R3=R4=H and R1 = C2H5, is the preferred acid.

In this manner, the amount of both the alkali and the catalyst can be reduced, and the conversion is increased.  Dehydrochlorination of 3,4-dichlorobutene-l gives chloroprene, which is a valuable monomer for making synthetic elastomers.

Abstract: ABSTRACT OF THE DISCLOSURE         In transferring solute from a liquid feed solution to a liquid extractant through a porous membrane, the feed solution and the extractant being substantially immiscible when in direct contact with each other, and one of them tending to preferentially wet the surface of the porous membrane to constitute a membrane-wetting liquid, the following process is employed.  A first side of the porous membrane is contacted with the feed solution containing the solute and the second side of the porous membrane is contacted with the liquid extractant so that the feed solution and the extractant can come into contact through the pores of the membrane.  An inter-face-immobilizing pressure difference is maintained between the feed solution on one side of the porous membrane and the extractant on the other side.  The pressure difference is maintained in a direc-tion across the membrane in a pressure range that is effective to substantially prevent the membrane-wetting liquid from flowing through the membrane and dispersing in the fluid on the opposing side of the membrane.  In this way the interface between the feed solution and the extractant at the porous membrane is immobilized.

Abstract: ABSTRACT OF THE DISCLOSURE         Cutting strengthened glass by means of a high velocity fluid jet.  A suitable fluid is placed under high pressure and directed against the surface of the glass in a highly collimated stream of small diameter at high velocity.  Very fine abrasive particles are aspirated into the high velocity stream prior to its impingement upon the glass to serve as a cutting medium for the strengthened glass.  The pressure of the fluid is reduced when starting the cut to avoid venting of the glass during initial penetration, and the pressure is then increased for movement of the fluid jet along the desired line of cut.  The relationship between fluid pressure, line speed and abrasive grit size is carefully controlled to produce a smooth cut free from vents and chips so as to avoid failure of the strengthened unit.
