Abstract: A tubing or pipe connector assembly primarily for use at cryogenic temperatures. The connector is of the screw thimble, gland type which is provided with a sealing member having a malleable metal seal partially inset in an annular groove in its radial face or faces. The sealing force for the seal is provided by spring members which are compressed when the threaded gland is screwed into the thimble. Materials used in the connector system are selected to effectively maintain the seal as temperature and pressure are cycled. The thread system of the gland and thimble and the deflection of the spring member can be selected so that after the connector components have been assembled to a fingertight condition, approximately a single turn of the gland finishes the connection operation.

Abstract: A cassette used to analyze a carrier liquid for the presence of a specific microorganism therein has a passageway extending through it and the passageway is provided with filter and viewing wells arranged such that each viewing well is preceded by a filter well. The carrier liquid is introduced into the passageway at one end thereof. Each filter well contains a filter material capable of effecting a one log reduction in the microorganisms within the liquid as the liquid passes through the filter. Each viewing cell contains plugs having a culture medium therein which is selective to a specific microorganism in the sense that only that microorganism will grow in the culture medium and change the light-transmitting characteristics of the viewing wells. To load the filter wells a pad of filter material is placed over the ends of the filter wells and the filters are simultaneously stamped from the pad and driven into the filter wells. To load the viewing wells, a flexible sheet of culture medium is placed over the ends of the viewing wells and the plugs are stamped therefrom and simultaneously driven into the viewing wells. The flexible sheet of culture medium is formed by adding a film-forming agent to liquid culture medium, pouring the solution so formed onto a surface, and then evaporating volatile components of the solution. After the volatile components evaporate, the flexible film remains.. The film-forming agent may be gelatin and glycerin, or it may be polyvinyl alcohol.

Abstract: Apparatus for the accurate placement of the conductive members and electrodes of acoustic surface wave devices formed on the surface of a substrate such as a piezoelectric substrate including means for mounting the substrate for movement on the movable base portion of a camera device, said substrate having a conductive input transducer formed thereon, but being without any conductive electrodes. The apparatus includes a pick-up sensor mounted externally of the movable base in position adjacent to the substrate, and means responsive to a reference signal of the same frequency as the frequency at which the acoustic surface wave device being constructed is to operate for driving and accurately locating the movable members including the movable camera base. The apparatus includes a phasemeter which is used to accurately reposition the table (camera base) to each succeeding electrode image position so that the relative phase of all electrodes of the acoustic surface wave device is assured, a condition made possible by the present apparatus inasmuch as the photomasks employed are also prepared under control of similar step and repeat control means. The apparatus may alternatively employ means to count the cycles of the RF signal as the table is moved.

Abstract: This application discloses a chemical conversion process and composition for producing an adherent conversion coating on titanium and its alloys. The composition comprises a combination of sodium hydroxide and a hexavalent chromium compound. The process comprises the treatment of the titanium part with the usual, well-known nitric-hydrofluoric acid solution and/or an alkaline cleaner to obtain a clean surface. Then the parts are exposed to the process of this application which produces a surface resulting in increased adhesion or retention of subsequently applied coatings such as chemical milling maskants, adhesive bonding materials, lubricants, other protective coatings, and enhances the adhesion of composite materials to titanium.
