Abstract: A container cap for use on an open top container having an upper end portion with an upper rim surface. The container cap is adapted to be mounted and sealed thereon, such that only a lift tab and a spaced apart peripheral segment extend beyond the outer edge of the upper rim surface. The non-extended edges of the cap adjacent the sides of the lift tab provide for the easy removal of the container cap in one piece upon manual lifting of the tab.

Abstract: A refractory insulation on boiler tubes using studs circular in cross-section and having shoulders intermediate their ends with washers frictionally engaged on the studs sandwiching a mesh therebetween. The shoulder restrains movement of the first washer and mesh toward the substrate and the second washer retains the mesh from movement away from the substrate. A first insulation is applied to the substrate through the mesh and a second insulation layer is applied over the mesh to a predetermined thickness determined by the height of the studs above the shoulders. Pins can be welded to the tops of the studs and used to impale fibrous insulation.

Abstract: A vehicle restraint assembly 10 having a selectively inflatable and expandable assembly 20 and a member 34 which is selectively and removably coupled to a vent member 30 and which overlays the assembly 20. The member 34 cooperates with the vent member 30 to direct and transport air within the vehicle passenger compartment 28. The selectively expanded assembly 20 causes member 34 to become selectively dislodged from member 30, thereby allowing assembly 20 to enter the vehicle passenger compartment 28 and to desirably protect the vehicle occupants.

Abstract: A method and several exemplary apparatus for capillary dewatering of foam materials. The apparatus may include felt which is applied to an exposed face of the foam material, or a double felt arrangement applied to two opposed surfaces of the foam material. The apparatus may provide a temperature differential between the two exposed surfaces of the foam material. An alternative embodiment utilizes a roll having a capillary dewatering medium. The capillary dewatering medium may be maintained at a vacuum either above or below the breakthrough vacuum of the capillaries. The disclosed apparatus and method is particularly useful for dewatering foams having relatively fine open capillaries.

Abstract: Disclosed is a shaped absorbent core suitable for absorbing and retaining aqueous body fluids. The absorbent cores comprise a front panel and a back panel. The front and back panels are made from fluid absorbent material, and each has an inner end, an outer end, and two sides. The inner and outer ends of each front and back panel have a length, with the inner end of each being shorter than the outer length of each. The front and back panels may comprise multiple layers of absorbent material. The absorbent cores also comprise a center section made from fluid absorbent material having first and second ends. The first end of the center section is in fluid communication with the front panel by overlapping the front panel intermediate the front inner and outer ends, and the second end is in fluid communication with the back panel by overlapping the back panel intermediate the back inner and outer ends.

Abstract: The present invention is a method to determine the water content and/or total organic carbon content in a petrochemical stream including water, organic carbon and acid comprising irradiating a feed stream including an acid, water, and organic carbon, with optical radiation; determining the optical absorption of the feed stream for at least two selected wavelengths; and determining the weight percent of the water and/or organic carbon content from the optical absorption.

Abstract: Knife shaft pair for cutting web-like material, in particular undulated board, wherein the knives contact each other temporarily under bias, if necessary, shortly before termination of the cutting operation, the cutting edge lying at the trailing side of a first knife being formed in a manner known per se so as to be uniformly continuous with an equal spacing from the shaft axis, the other knife having a saw-toothed cutting edge whose teeth extend, commencing from the continuous line of contact with the first knife, away from the shaft of the second knife and in the approximation region of the knives at an acute angle to the connecting plane between the line of contact and the uniform cutting edge such that they lie at the trailing or the leading side of the first side during the cutting operation.

Abstract: A machine for the assembly of frames, e.g. of timber, comprises a first static assembly (6), and a second assembly (8) mounted for longitudinal movement relative to the first assembly (6). The static assembly (6) comprises two adjustable side assemblies (16), and supporting assemblies, comprising support members (20, 22) providing parallel spaced supporting surfaces (23) on which elongate frame members (26) may be positioned. The moving assembly (8) carries clamping devices (60) each of which provides a datum surface, and an air cylinder to move the datum surface between operative and retracted positions, and a power operated clamp member to urge a transverse component (120) of the frame into engagement with the two datum surfaces.

Abstract: An improved ophthalmic needle and method for manufacturing the same for use with an ophthalmic instrument for extracapsular removal of a cataract. The needle comprises a coaxial tube portion, a separated tube portion, and a tank portion, interposed therebetween for flow conversion purposes. A metal-to-metal seal is effectuated between tubes at the coaxial portion by a spinning method employing a forming die in conjunction with a lathe. A unique use of fixtures is employed to properly orient the various tubes with respect to the tank and to effectuate joint sealing.

Abstract: Photographic elements, such as still films, motion picture films, paper prints, microfiche, and the like, are provided with a protective overcoat layer which is permanently bonded to the element and serves to protect it from abrasion and scratches. The protective overcoat is formed by coating the element with a radiation-curable composition, comprising an acrylated urethane, an aliphatic ethylenically-unsaturated carboxylic acid and a multifunctional acrylate, and irradiating the coating to bond it to the element and cure it to form a transparent, flexible, scratch-resistant, cross-linked polymeric layer. Protective overcoat layers can be applied to the image-bearing side of the element or to the support side of the element or to both sides.
