Abstract: A pipe connecting assembly and method for joining two lengths of steel pipe in the field without the need for welding the connection includes a pair of tubular members both having cylindrical exterior and interior surfaces that substantially conform to the exterior and interior surfaces of the two lengths of steel pipe. At one end of one of the tubular members a male connector is formed. The male connector has a plurality of annular flat and tapered ridges and flat annular surfaces formed thereon. At one end of the other tubular member a female connector is formed. The female connector has a plurality of flat annular ridges and tapered and flat surfaces forced thereon. In employing the tubular members in connecting the two lengths of steel pipe, the ends of the members opposite the male and female connectors are first welded to opposed ends of the steel pipe.

Abstract: An opening 11 is formed in a region of a circuit board 10 opposite to a vibration region E of a piezoelectric element 5. The piezoelectric element 5 is mounted on the circuit board 10, and electrode connection portions 9 of the piezoelectric element 5 are connected with and fixed to the circuit board by a solder. In succession, soldered connection portions kept away from the vibration region E of the piezoelectric element 5 are filled with a bonding agent 8. Thereupon, an excess bonding agent 8 with which the soldered connection portions are filled is eliminated by the opening 11, and hence is prevented from invading the vibration region E of the piezoelectric element 5. Further, any stress exerted on the circuit board 10 is dispersed because of its being mostly received by the bonding agent 8, and hence any stress exerted on the piezoelectric element 5 is reduced.

Abstract: A wire ribbon has a plurality of insulator-coated conductive wires, each having an insulating layer formed on a surface of a conductive wire. The insulator-coated conductive wires are arranged parallel in a row to be adjacent to each other. The adjacent insulator-coated conductive wires are bonded to each other through interconnection adhesive layers so as to be integrated. A thermoplastic adhesive interlayer having an adhesion temperature lower than that of the interconnection adhesive layer is formed in a local circumferential region on an apex of each single-core wire on at least one of upper and lower surface sides of the wire ribbon.

Abstract: A shelf and support arm assembly is comprised of a wire shelf having two different embodiments, the support surface of the shelf being formed by a plurality of parallel, spatially arranged longitudinal wires where a given lateral spacing between the wires differentiates one embodiment of the shelf from another. A support arm is suspended from a forward end of the shelf to facilitate the assembly of the shelf and support arm to a vertical support surface. The support arm is specifically configured so that the same support arm may be employed in attaching both embodiments of the shelf to the vertical support surface.

Abstract: The present invention relates to a flashlight for use by firefighters and for use in other specialized areas. In particular, the present invention relates to a flashlight comprising a body of substantially parallel, spaced tubular members that each contain a plurality of dry cell batteries for powering the flashlight. A lamp is connected at one end of the pair of tubular members for pivoting movement relative to the members through at least 90.degree.. A support base is connected across the opposite ends of the tubular members and is configured to support the flashlight on a surface with the pair of tubular members positioned upright and elevating the lamp above the surface. The support base is removable from the ends of the tubular members to provide access to interiors of the members for inserting or removing dry cell batteries to power the flashlight. Adapters are provided for each of the tubular members to adapt their interiors to accommodate either D-size dry cell batteries or C-size dry cell batteries.

Abstract: An improved aperture for a scanning microscope as is used to mask either or both of the incident light and reflected light includes a plurality of continuous curvilinear slits spaced evenly about a common origin, each of which approximates an Archimedes' spiral emanating from the origin centered on the aperture. There are two embodiments of the invention disclosed, both of which have a true Archimedes' spiral to define the inner edge of the continuous slit. In a first embodiment, the outer edge is defined as having a constant proportional circumferential aperture distance from the inner spiral. In the second embodiment, the outer edge is defined as another Archimedes' spiral having a constant offset of minimum distance from the inner spiral. However, the outer edges of the two embodiments essentially merge in a physical sense after only several of the inner revolutions of the continuous slit so that the continuous slit of either embodiment provides an image having uniform masking and uniform resolution.

Abstract: An integral wire shelf and hanger rod having a plurality of support brackets for interconnecting the rod with metal shelf. Each support bracket has a U-shaped section and spaced upper and lower arms welded respectively to the shelf and the hanger rod. The configuration of the support brackets permits a garment hanger to slide across the rod through a path uninterrupted by the support brackets.

Abstract: An apparatus for use in the performance of thin layer chromatography of the type which utilizes a thin bag as the developing chamber for the chromatogram is provided. The apparatus has a pair of substantially identical frames which hold the bag between the frames in a manner sealing the upper and lower ends of the bag while permitting sliding movement of the bag vertically within the frame. The frames are connected by a hinge which permits pivoting of the frames between an open and a closed position. In the closed position, the inner surfaces of the frame are aligned in a face-to-face relationship which accommodates the placement of the chromatography bag between the frames and holds the bag in an upright manner by frictional engagement of the bag with the inner surface of the frame. The bag is sealed by the action of outwardly extending ribs or a resilient pad presented on the inner surface of at least one of the upper and lower crossmembers of the frames.

Abstract: A trigger sprayer apparatus is comprised of a sprayer housing and a vent housing that are formed independently of each other and are then assembled together. By providing a separate sprayer housing and vent housing, the sprayer apparatus may be produced in a manner that significantly reduces the occurrence of deformations or imperfections in the component parts of the apparatus. Molding the sprayer housing and vent housing separately enables the cylindrical interior surface of the pump chamber and the cylindrical interior surface of the vent chamber to be molded more accurately. Because the sprayer and vent housings are molded separately, a lesser amount of material is needed to mold each of these components and therefore shrinkage of the material as the components cool is significantly reduces. This eliminates the occurrence of deformations or sinks in critical areas of these component parts.

Abstract: A fire resistant and high temperature insulating composition is provided. The composition generally comprises a carbonate material in an amount from about 20% to about 80% by weight, an aluminosilicate in amount from about 0.5% to about 15% by weight, talc in amount from about 0.5% to about 10% by weight, cellulose in amount from about 1% to about 30% by weight, a binder in an amount from about 1% to about 45% by weight, and a gelling agent in an amount from about 1% to about 45% by weight. The binder is preferably a mixture of an organic adhesive such as a polymeric resin, and a non-organic adhesive such as cement, but other adhesives can be used alone or in combination therewith. The gelling agent is preferably a polymeric substance that swells in the presence of a liquid such as superabsorbent polymers. The components are combined and water may be added in an amount from about 1 to about 50% by weight to obtain a composition of the desired consistency.
