Abstract: A hood suitable for protection against decompression and toxic fumes, prepared using a laminar structure of polyimide, two or more layers of fluoropolymer and heat sealable polymer that affords the heat resistance of polyimide with a markedly lower internal noise level, ease of fabrication and resistance to etching by flame. An improved neck seal is also provided.

Abstract: An improved electrodepositable cationic resin is disclosed. Prior art electrodepositable cationic resins are formed from polyepoxides which are chain extended with polyether or polyester polyols to internally flexibilize the resin. The polyepoxide resin of the invention is chain extended with a monoepoxide-triol adduct which provides a resin with improved throw power and improved flow while maintaining other important characteristics of the resin.

Abstract: A multilayer plain bearing composed of a backing layer, an intermediate layer and a diffusion or bonding layer, and a sliding layer, the sliding layer being of a laminate structure formed by the alternate deposition of layers of a softer material and layers of a harder material.

Abstract: A modular multi-passage rotary coupling for transferring fluids in which pipes are rigidly connected with the inner fixed rings of the relevant modules by sleeves. The sleeves, after being coaxially butt-fastened at their bottom end with the pipes, enter proper bores specifically provided in the relevant fixed rings, inside which each of them is fastened under pressure by means of a closure and tight-sealing screw-threaded cap which is screwed down on a corresponding inner threading provided at the upper end of the relevant sleeve and urging, with the crown of its head, against the upper edge of the bore and also by a shoulder step jutting out at the bottom end of the sleeve and cooperating with the lower edge of the bore of the fixed ring.

Abstract: Batch process control is improved by defining a step endpoint condition in an expert system knowledge base; using the expert system to monitor for the occurrence of the endpoint in the batch process; and triggering a change in a batch process condition when the endpoint is found. Preferably, the expert system and the batch process condition change are implemented as modules which execute under control of timing and sequencing functions in a supervisory control system, and the change affects a setpoint (or other control objective) in a continuous control system. Multiple instances of modular expert systems allow parallel process units to be easily controlled.

Abstract: A deformable shim assembly for positioning a closure unit in building framework defining a rough opening. The system includes a plurality of flexible, generally identical shims each having a cylindrical surface curvature to provide a convex outer surface and a concave inner surface. The forward end of each shim is tapered and is defined by side edges with an angle of intersection bisected by the axis of symmetry. The side edges also define a plane that intersects the cylindrical outer and inner surfaces at an acute angle to define a wedge-shaped space. The space has a transverse cross section in the shape of a circular segment that diminishes progressively toward the forward end of the element.

Abstract: The present invention refers to a process for the manufacture of a basically cylindrical container provided with a can end which is lock-seamed to a longitudinally welded body without the risk of scratching the inside of the can body, by providing a sequence of operations which is adapted to high volume production, including the steps of preparation of the can body, preparation of the can tap, seating of the tap or can end, moving the can body, applying an axial force to the body wall, and transferring the can body with the can end to a final lock seaming operation.The present invention further describes apparatus associated to the new steps of the process as well as to a specific machine for lock seaming which includes such devices, and to a can end to be lock seamed by the process.

Abstract: The present invention relates to electrical connectors for electrically connecting components and circuits on or in two parallel circuit boards and, more specifically, for electrically connecting components and circuits on or in two parallel circuit boards having a high density of interconnections.

Abstract: A fowl drinker, having a water intake device, characterized in that the water flow adjustment means is not the same as the means with which the valve body is attached to the support column, but is formed by a stem (31) freely inserted in a tubular widened diameter portion (32) of the cup-shaped cover (29) and connected at the top and the bottom thereof, respectively, to a resilient stopper (30) engaging the spout (24) of the valve body (18) water outlet and a blind nut (33) screwed on the widened portion (32) and with which the adjustment is made, without a subsequent dismantling and reassembly of the drinker altering it, the valve body (18) being snugly fitted over the support column (15) to prevent the weight of the water supply conduit from upsetting it, affecting said regulation. The support (39) of the bushing (44) which is connected to the pipeline t comprises a flexible strip (17) surrounding said pipeline.

Abstract: A beta phase of molybdenum trioxide or the mixed metal oxides of molybdenum and tungsten is prepared by spray-freezing then freeze-drying, affording a powder which is then heated to a temperature of 275.degree. C. to 450.degree. C.

Abstract: This invention relates to electrical connectors with a ground structure for impedance and cross talk control between signal carrying conductors and, in particular, where the connector is a right angle or angled receptacle.

Abstract: A releasable overshot having independent slips, for retrieval of downhole tools and other equipment, which can be operated with a wireline, tubing, coiled tubing, or drill pipe string.

Abstract: Compounds of the formula ##STR1## are disclosed. These compounds are inhibitors of renin and therefore useful as cardiovascular agents.

Abstract: A coextrudable adhesive composition comprises a blend of (a) a copolymer of ethylene with alkyl acrylate or methacrylate comonomer and a grafted comonomer containing pendant carboxylic acid or carboxylic acid derivative functionality, and (b) a copolymer of ethylene with at least one comonomer selected from the group consisting of alpha olefins, nonconjugated dienes, vinyl esters of carboxylic acids, styrene, alkyl acrylates, and alkyl methacrylates, wherein component (b) is incompatible with component (a).

Abstract: The locality of a two dimensional gray level image from which is generated a reference threshold value for converting the image to its corresponding binary image is determined by finding the fractal dimension of a hypothetical three dimensional surface overlying the two dimensional image.

Abstract: A reciprocating pump valve and seat having mating frustoconical seating surfaces in which a resilient sealing insert on the valve is below a rigid disc portion of the valve, with a sealing surface on the insert engageable with the seating surface of the seat radially outwardly from the portion of the seating surface of the seat engageable by the rigid disc portion of the valve.

Abstract: This invention pertains to novel heterocyclic 2,3-dihydrobenzofuran and chromane compounds, including stereoisomers, agriculturally suitable compositions containing them, and their use as broad spectrum herbicides.

Abstract: A process is disclosed for providing benzazepine intermediates of the formulae ##STR1## wherein R.sub.3, R.sub.4 and Y are as defined herein, which intermediates are useful in a process for the preparation of pharmaceutically useful benzazepine derivatives.
