Abstract: ABSTRACT OF THE DISCLOSURE          A bimetal snap disc thermostat is disclosed in which a steel disc cup is provided for strength and/or environmental resistant properties.  Positioned within the disc cup is a disc seat formed of aluminum.  A bimetal snap disc is positioned in the disc seat and operates the thermostat switch through an axially movable bumper.  A ring of rubber like foam material is positioned between the body assembly and the disc on the side of the disc remote from the disc seat.          The aluminum disc seat reduces temperature calibration drift of the disc during the cycling of the disc which occurs during the use of the thermostat.  The reduction of calibration drift when compared to similar devices employing steel disc seats results from the cushioning of the impact on the disc and the reduced bouncing of the disc when it snaps against the aluminum disc seat.  The foam ring also tends to reduce bouncing and thereby tends to reduce temperature calibration drift.          Also the ring functions to insure that the disc remains properly seated in its aluminum disc seat.

Abstract: ABSTRACT      A dimensionally-recoverable article comprising a hollow resilient member which has been expanded to a dimensionally unstable configuration in which it is retained by a keeper positioned between and separating two parts of the hollow member away from the path of recovery thereof. The keeper is preferably made from a fusible or chemically degradable material so that it can be removed, for example by heating or chemical treatment to allow the hollow member to recover towards its original configuration. One preferred form of article is a radially-expanded longitudinally split tube having the keeper positioned within the split. Such an article may be used as a connector to secure an earth lead to the sheath of a mineral-insulated cable.

Abstract: ABSTRACT OF THE DISCLOSURE            The amount of oil recoverable from a subterranean, petroleum-containing, permeable formation by surfactant water flooding is improved is at least two separate slugs of surfactant-containing fluid are injected into the forma-tion, the first being a fluid containing a surfactant which is an effective emulsifier for the petroleum in the formation and the second surfactant fluid containing a surfactant which does not produce an emulsion between the aqueous fluid and the formation petroleum, but which is effective for achieving maximum oil recovery, or for achieving the minimum interfacial tension between the aqueous phase present in the flow channels of the formation and the formation petroleum  In one embodiment, both surfactants are an aliphatic (e.g. alkyl) or alkylarylpolyalkoxyalkyl sulfonate, differing only in the average number of alkoxy groups per molecule.  The first emulsifying surfactant contains an average of from .2 to .8 fewer alkoxy groups than the second surfactant.  The proper surfactant may be identified by determining which alkyl or alkylarylpolyalkoxy-alkyl sulfonate produces the maximum amount of emulsion with the formation brine and formation petroleum, employing that surfactant in the first surfactant fluid, and then employing a surfactant containing from .2 to .8 more alkoxy groups per molecule in the second surfactant fluid.  In a slightly different embodiment, the alkyl or alkylarylpoly-alkoxyalkyl sulfonate which achieves the minimum interfacial tension between the aqueous fluid present in the formation flow channels and the formation petroleum is identified, and is utilized in the second surfactant fluid, and the surfactant employed in the first fluid contains from .2 to .8 fewer alkoxy groups per molecule than the surfactant in the second fluid.

Abstract: IMPROVEMENTS IN BATTERY PLATE WRAPPING MACHINE                 A B S T R A C T The invention relates to improvements in a machine and method for enclosing battery plates within a pouch or envelope of sheet separator matexial. In such machines a length of such sheet is positioned in spanning relationship to a folding aperture or slot and a plate injector shuttle is mounted for reciprocating movement into and out of the folding aperture so that when a battery plate is mounted on the injector shuttle the movement of the injector shuttle into the folding aperture effects the folding of the sheet about the leading edge of the injector shuttle and the battery plate mounted thereon.  This invention provides a pair of grasping tongs mounted in laterally spaced positions on an extractor shuttle which in turn is mounted for reciprocating movement along a path parallel to the injector shuttle and on the opposite side of the folding aperture.  The gripping portions of the tongs swing inwardly under each side of the envelope plate emerging from the folding aperture but at the same time tongs are disposed laterally outward of a wrapped plate conveyor which has its conveying surface aligned with the path of the in-jector shuttle.  This arrangement permits the contin-uous operation of the injector and extractor shuttles without any delay period because neither the wrapped plates nor the extractor tongs interfere with the reciprocating movement of the extractor shuttle and the gripping tongs.
