Abstract: A relatively fast process for producing HNS from trinitrotoluene (TNT) in high yield consists of oxidizing TNT with an oxidizing transition metal compound within a polar aprotic solvent having a weak base, such as an alkali metal carboxylate, dissolved therein. The amount of transition metal compound used is typically at least one mole per mole of TNT. An especially preferred transition metal compound for use in the present process is cupric chloride.

Abstract: A vehicle, preferably "hatchback", rear window defroster electrical connector using an adhesively secured threaded post to receive thereon a circular electrical element which is pressed into an electrical connection by a nut against the defroster conductive deposit on the rear window, thereby avoiding the use of solder which deteriorates upon exposure to weather elements occasioned by the frequent opening of the hatchback rear window door or panel.

Abstract: In a window pane mounting arrangement, there is proposed an improved window moulding which can be neatly fitted to a clearance defined between the edge of the window pane and the peripheral flange of the window opening. The window moulding comprises an elongate band portion adapted to cover the clearance and a leg portion depending from the inboard surface of the band portion and disposed in the clearance. The improvement consists of openings in the leg portion to permit the flow of sealant therethrough to relieve pressure in the sealant while it cures, which pressure, if not relieved, would lift or otherwise adversely effect the positioning of the moulding.

Abstract: An automotive window assembly of the type having a stationary window assembly insertable onto a peripheral flange of a rabbet flanged window aperture which is formed in an automotive vehicle body. The window assembly is designed to be adhesively secured to the automobile body after being mounted on the peripheral flange. The window assembly includes a plurality of cup-shaped retention elements which have inner sides fixedly secured to the inner pierpheral surface of the window assembly. Each retention element has a resilient outer side, and a generally perpendicular, outwardly extending stem joined at one end thereof to the resilient outer side of each of the plurality of retention elements. The stem is inwardly deflectable about the joint formed at the one end thereof and the resilient outer side of the cup-shaped retention element.

Abstract: An apparatus for retaining a window panel on an outer surface of a flanged body panel of an automotive vehicle body is to be used with a curable adhesive. The apparatus utilizes a decorative trim portion adapted to bridge the space between the window panel and the flanged body panel while overlying both the outer surface of the window panel and outer metal frame of the vehicle body. The decorative trim includes a resiliently yieldable stem extruded integrally therewith and extending generally perpendicularly therefrom for insertion into the space between the window panel and the body panel. The stem includes extensions which extend generally radially outwardly therefrom and are adapted to project into the curable adhesive, thereby attaching the decorative trim portion to the vehicle body. A flange on the flanged body portion includes a plurality of holes communicating with the space between the window and the body. A plurality of retaining elements are attached to the inner surface of the flange.

Abstract: A reusable retainer includes a multi-layered generally annular assembly defining a central opening formed therethrough. The assembly is composed of at least one relatively resilient layer and at least one relatively rigid layer with the said rigid layer being split to allow the assembly to radially expand or bend.

Abstract: A glass panel carrier, especially intended for automobile windshields includes a pair of generally parallel, laterally spaced-apart support rails, and at least one transverse support member disposed in between and attached to the rails. A multiplicity of fittings each having at least one branch leg, are slidably supported in fixed positions on the rails and are mounted with the branch legs positioned generally perpendicular to the rails, the fittings being configured to prevent any axial rotation thereof. A multiplicity of posts are provided, each of which is associated with one of the T-shaped fittings, with the post releasably engaging the branch leg of the associated fitting. The posts in adjacent fittings on each rail and opposing fittings on the opposite rail cooperate in holding glass panels therebetween during transport and/or storage thereof.

Abstract: In the assembly of an auto glass window to the mounting bracket portion of the operator which raises and lowers the window, the improvements which consist of notches in opposite corners of the glass window bottom edge and cooperating tabs on the mounting bracket which bend forward over gripping surfaces formed by the notches, and thus engage the glass window more firmly than the prior art adhesive engagement, thereby obviating the loosening of the glass window particularly during descending movement thereof against the friction of the window tracking guides.

Abstract: A process for the manufacture of 2,2', 4,4', 6,6-hexanitrostilbene (HNS) from dipicrylethane (DPE) or trinitrotoluene (TNT) which consists of oxidizing DPE or TNE substrate in the presence of an aprotic solvent and a basic salt of a carboxylic acid. The acid preferably consists of an ammonium or an alkali metal salt of a monocarboxylic or a dicarboxylic acid. The reaction step consists of heating the substrate and salt dissolved in the solvent to between 15.degree. and 50.degree. C., and contacting the reaction mixture with dry air or oxygen for up to 2 hours. The HNS product is precipitated out by quenching the reaction mixture in acidified water, and is optionally purified by washing first in methanol and then in acetone.
