Title: Electrical plug and socket connector for ceiling fitting - for engaging notches of socket and stuffing gland for immobilising flex
IPC: H01R13/62
Filed: 1983-05-10
Abstract: A conventional plug with two or more pins has a symmetrical profile and circular section with lugs on the outside to ensure retention in the ceiling socket. The body of the connector incorporates slots in its cylindrical wall to accept the lugs, and can be rotated clockwise through one-sixteenth of a revolution so that its own lugs engage in notches of the socket. The widened end of the body receives the plug, while its tubular part incorporates a stuffing gland for immobilising the flex. The ceiling socket is conventional except in that its plate has notches formed in the periphery of the tapered cylindrical part to engage the lugs. A fixed socket may be coupled to the end of the flex.

Abstract: ABSTRACT OF THE DISCLOSURE        Petroleum feedstocks comprising the isomeric forms of saturated C5 and C6 hydrocarbons are totally iso-merized with respect to their straight chain fraction by separating the normal from the non-normals by selective adsorption based on molecular dimensions and isomerizing the normals in contact with a zeolitic molecular sieve catalyst.  The normal paraffins are separated from admix-ture with the non-normal hydrocarbons in a vapor phase non-sorbable purge process in which three fixed bed molecular sieve adsorbers are operated so that variations in the con-centration of hydrocarbon molecules in the feed to the isomerizer are kept to a minimum.

Abstract: TWIN CHECK VALVE PUMP SYSTEM HAVING FAIL-SAFE CHARACTERISTIC                Inventor:  Robert A. Virag ABSTRACT OF THE DISCLOSURE     A twin check valve pumping system for use with a syringe or other variable volume pumping device for the pumping of liquids.  Along a flow path between the check valves, a porous, hydrophobic member is positioned, in communication with a portion of the flow path upstream of the first, inlet check valve.  The second, downstream out-let check valve is biased so that pressure in the conduit between the check valves is required for expulsion of li-quid.  When gas enters the system, such pressure cannot be achieved, because, upon attempted pressurization of the area between the two check valves, the gas passes through the porous, hydrophobic member hack to a position upstream of the first, inlet valve.  However, aqueous liquids cannot pass through the porous member, and accordingly the device pumps such liquids normally in the absence of gas.
