Abstract: CIRCUIT BREAKER CLOSING MECHANISM ABSTRACT OF THE DISCLOSURE          A circuit breaker the moving contacts of which are closed by a charged spring or plurality of springs in which the circuit breaker is of minimum size for any given application and maximum simplicity in manufacture.  The circuit breaker closing system is a cam closed system in which the closing cam acts also as a prop latch for supporting the spring operating mechanism in charged position.  The cam follower path is determined by three cam surfaces between which the closing forces are transmitted through free floating rollers; this obviates the need for toggle links for the transmission of forces or the guiding of the cam follower rollers.  This arrangement, by permitting the distribution of the variable mechanical advantage of a cam slope among three members, instead of building it into just one member allows the use of a smaller diameter primary closing cam; it also permits an application of closing forces appropriately tailored to the requirements of each circuit breaker.          This application is related to and filed simulta-neously with Canadian applications Serial Numbers 285,925 and 285,978 in the name of George A. Wilson and assigned to the assignee of the present case.

Granted: 1982-05-11
Abstract: ABSTRACT OF THE DISCLOSURE             A suspension or solution containing an acid-curable fluoride-containing resin which is useful in a foundry process is disclosed.  The fluoride-containing resin is curable at room temperatures and above by the addition of a strong acid catalyst.          The resin is preferably a phenolic resole resin or a furan-type resin.  The fluoride-containing resins, when used in a foundry process are preferably admixed with a foundry sand and a strong acid catalyst.  The coated sand is then shaped into the form of a foundry core and is allowed to cure at room temperature or above to a foundry core having excellent tensile strength.

Abstract: WEFT KNITTED RASCHEL-LIKE THERMAL FABRIC, AND METHOD OF KNITTING THE SAME                         Abstract A weft knitted thermal fabric simulating raschel thermal fabric in appearance and in heat insulating property. The fabric has a multitude of air-entrapping cells formed on at least one side to provide dead air spaces, thereby giving the fabric an enhanced heat retention quality.  The air-entrapping cells are three dimensional cavities defined by spaced side walls and spaced top and bottom walls.  Each wall comprises elevated fabric formed of two separate, closely spaced, wale-wise extending, ribs of knitted stitches, the stitches of the two ribs being connected and drawn together by yarn floats. The air-entrapping cells are provided with floors composed of a knitted wale formed of alternating tuck loops and knitted stitches.  The fabric is knit on a 1 x 1 rib knitting machine operated in alternating repeat sequences to produce knitted stitches, floats and tuck loops selectively in the fabric, to provide successive rows of air-entrapping cells, with the cells of each row staggered relative to the cells of the next adjacent rows.

Abstract: Docket 2457 DEMAND INHALATION VALVE SYSTEM                            Abstract of the Disclosure A valve body (28) defines a chamber (65) having an inlet (72) connected to a gas supply and an outlet (29) connected to a face mask. The valve body supports a flexible diaphragm (40) connected by an adjust-able lever mechanism (59, 118, 110) to a movable valve member or piston (95) so that the diaphragm opens the valve piston in response to a pre-determined differential pressure across the diaphragm produced by inhalation.  The valve also includes differential gas pressure means (80, 92, 102) for further opening the valve piston in response to a suction force produced by the flow of gas past the valve piston and independent of the diaphragm actuation to provide for minimizing the inhalation effort by the individual regardless of the volume of gas demanded during inhala-tion.  The valve piston is closed in response to a light force of a spring (103) when the differential fluid pressure ceases and the supply gas pressure acts on a differential area of the valve piston (95) to hold the valve closed.

Abstract: BOUND AGGREGATE METHOD AND COMPOSITION     ABSTRACT OF THE DISCLOSURE         A method and composition is disclosed which is particu-larly suitable for forming a firm, bound aggregate-water support for floral arrangements with at least 60% by weight water.  The composition comprises a water-insoluble, water-retaining binder, such as a particulate, water-insoluble, water-swellable, cross-linked polymer, and inert non-packing, highly porous water-trap-ping, aggregate particles dispersed throughout, the particles being present in an amount and having a bulk density and surface area effective to disperse the composition throughout the water as the composition is added to it without hand kneading or stirring.          The binder should have water retention properties of at least 100gm/gm.  The aggregate particles should have an open structure and water retention properties of at least 4gm/gm, have a surface area of at least about 10m2/gm and an apparent bulk density of not over 30lbs/sq.ft. to avoid packing.  Only sufficient binder should be present to firmly bind the aggregate particles together, for example from about 0.1% to about 1.0% by weight, although higher amounts of binder can be used.  Rice hull ash is preferred as the aggregate and the preferred binder is a starch, acrylonitrile graft copolymer.  For most cut live flowers and to avoid mold, the composition should be acidic, but not too acidic to break the bond, for example a pH down to about 5.5 for some binders is satisfactory; although a pH down to 4 and below for cut flowers is satisfactory so long as the binder's bond is not broken.  If desired, a higher pH, for example up to about 8.5 can be used.          Advantageously, the composition can be added to water in a con-tainer of any size or shape in an amount sufficient to form the bound aggregate and the composition sinks in and disperses through-out the water and forms a support without the need for mixing with a mixer or kneading with the hands.  Advantages and representatives uses are set forth below.
