Abstract: A seal and lock includes a flexible metal cable held permanently at one end in a housing, the other end being insertable through the housing and is locked therein by a spring-biased ball which wedges against the cable upon an attempt to pull the cable from the housing. A second ball is located between the spring and the first-mentioned ball, and wedges against the cable to further prevent removal thereof and to prevent twisting of the cable as a way of removing the cable from the housing. The second ball is of sufficiently soft material so that the cable when pulled digs into the second ball to increase the jamming force against the cable.

Abstract: A reading light, disclosed in the context of an aircraft reading light, includes a lamp which is normally selectively aimable by swiveling a mounting assembly relative to a stationary base held in a panel. A rotatable two-positioned means, such as a ring, permits such swiveling in a first position of the ring and prevents such swiveling in a second position of the ring.

Abstract: A surgical saw having a base blade portion, a plurality of staggered teeth and an intermediate blade portion, the thickness of which is less than the thickness of the base blade portion. The thickness of the intermediate blade portion is sufficiently less than the thickness of the base blade portion to permit passage of bone cuttings and other material away from the staggered teeth during operation of the surgical saw.

Abstract: A composition suitable for use as a primer coating for a substrate which comprises a halopolymer, an epoxy resin, and an oxide of titanium. The epoxy resin and oxide of titanium are present in amounts effective to provide a primer coating of the composition over a substrate. Preferred halopolymers are ethylene/chlorotrifluoroethylene copolymers and ethylene/tetrafluoroethylene copolymers. Preferred epoxy resins include bisphenol A based epoxy resins and epoxy cresol novolac resins. A preferred oxide of titanium is titanium dioxide. Such compositions are particularly useful as primer coatings for metal substrates.

Abstract: A method of temporarily attaching items to be screen printed to a pallet. The invention includes providing a pallet pad of adjacently adhered sheets on a pallet. Each sheet of the pad has a non-transferable adhesive coating on a substantial portion of its upper surface. The upper coating on each sheet permits the superjacent sheet to be removed without adversely affecting the adhesion of the coating. The upper coat on each sheet, once exposed, is capable of removably retaining textile articles thereon. Providing a bottom most sheet of the pad has a non-transferable adhesive coating over a substantial portion of its lower surface as well, adhering this lower coating of the pad on to the pallet and removably mounting a textile article to the adhesive coating of the upper surface on a topmost sheet of the pallet pad.

Abstract: An elastomeric clamp for securing an associated tubular member to another object and for isolating and dampening vibration comprises upper and lower elastomeric portions. The upper and lower elastomeric portions are joined at one end by an elastomeric hinge and near the other end by a closure means. An associated tubular member is compressively received within the opposing faces of the upper and lower elastomeric portions. The compressive force provided by the closure means deforms the elastomeric upper and lower portions about the tubular member, providing improved vibration isolation through the elastomeric nature of the upper and lower portions and hinge.

Abstract: A rotary, die cutting anvil system having a rotatable head with a cover mounted on the peripheral surface thereof. The cover includes inner and outer laminated layers. The outer layer is made of a generally tough resilient composition that is softer than the hard inner layer to which it is bonded. The inner layer has holes for receiving pins. The cover is mounted on the head by forcing the pins into the holes. The resilience and shape of the hard inner layer maintains the cover on the anvil until it is pryed off. The pins may be fixed to the anvil head or be fixed on rings or sleeves slidably mounted in grooves on the periphery of the anvil head to permit linear or oscillatory freewheeling.

Abstract: A ball seal having an elongated, flexible metal strap for providing locking engagement with a ball-shaped housing. A locking platform, having two frangibly joined leaves, is mounted in the housing for receiving the ends of the metal strap. A pair of locking tabs are located on one leaf and a pair of locking rings are mounted on the locking platform. The seal is placed in use by passing the strap through a structure to be sealed and then sliding the ends into the locking platform to effect locking engagement between the strap ends, and the locking tabs and rings. If the strap is forced from the housing, the leaf having the locking tabs thereon will be torn from the other leaf at the frangible joint, thereby destroying the locking platform beyond reasonable repair.

Abstract: Dienes and/or acetylene impurities in an olefin feed; in particular a propylene feed, may be selectively hydrogenated in a single stage by use of a catalyst of palladium supported on alumina which is substantially crystalline alpha alumina, wherein the average pore radius is 200-2000 .ANG., with at least 80% of the pores having a pore radius within the range of 100 to 3000 .ANG.. The surface acidity of the catalyst is generally from 0.002 to 0.05 millimole of pyridine absorbed per gram of catalyst. The active palladium surface area is from 20 to 200 m.sup.2 /g. The palladium is in the form of crystallines having an average size of at least 25 .ANG..

Abstract: A prosthesis having a stump-receiving socket and a plurality of inflatable bladders with a means for the user to vary the pressures therein. The inflatable bladders each include a relatively soft, flexible membrane made of a suitable material such as polyurethane. The membranes are shaped to meet the anatomical characteristic of the wearer. Those membranes located adjacent the weight-bearing portions of the stump will provide a relatively soft uniform surface to support the stump. For those locations near the weight-bearing portions of the stump that should not be subjected to pressures, the adjacent bladder areas are non-inflatable and, therefore, not force inducing. The static pressures in the various bladders are independent of each other and may be regulated by the user.

Abstract: A prefabricated modular unit construction bridging system in which all components are identical and interchangeable to meet any variation of span, width of roadway, number of lanes of traffic, and live load specification for any temporary, semi-permanent, or permanent bridge. The bridge is capable of being dismantled and the individual modular components used elsewhere to form a new bridge. The panels, when connected end-to-end to form the main load-bearing trusses of the bridge side girders, are of such a shape that they can be pinned together at their bottom chord level to support the standard cross-beams and modular deck units/bracing throughout the bridge and provide gaps between adjacent panels at their top chord level into which can be pinned other standard chord units of such a length calculated to eliminate entirely both the natural pin-hole deflection inherent in 2-pinned modular truss structures and the elastic deflection under dead load.

Abstract: A padlock-type security seal including a U-shaped shackle having a pair of reversely bend end portions. A body portion and a brightly colored insert are assembled to form a pair of chambers for receiving and locking the bent end portions. Movable tangs and matching cavities are formed as an integral part of the insert adjacent the chambers. The body portion has a plurality of transparent windows adjacent the cavities. Attempts to open the seal by deforming the shackle to remove the bent end portions from the chambers will result in moving the tangs into locking containment with the cavities thereby visually indicating tampering via the transparent windows.

Abstract: A padlock-type security seal having tamper-indicating means to cause the shackle ends to break through and protrude from the walls of the seal body when serious attempts are made to remove the shackle. The seal includes a pair of slots each having a shoulder for engaging the shackle ends. When serious attempts are made to force the shackle from the seal, a ramp will engage the shackle ends and force them against the seal walls. With sufficient force applied to the shackle, the shackle ends will rupture the seal body.

Abstract: A color match predictability system having a color sample, a predictability guide with sections having varying degrees of halftones, a spectrophotometer, and a computer with input and output devices. A light is directed at the color sample and then passed into the spectrophotometer where its color spectrum is analyzed, converted into data, and fed to the computer. A colorant formulation is calculated by the computer for the original color sample and for a series of modified samples including different halftone sections superimposed on the original color sample. The quality of the color match for the various formulations is analyzed to determine the formulation having the best possible color match. The modified sample having the best color match may be viewed by the user to predict the color of the final product.

Abstract: A novel adhesive is described, consisting of a matrix-matrix polyblend of polymer components useful in an adhesive tie layer to bond incompatible polymer layers. The adhesives are a blend of the components making up the incompatible polymer layers themselves, or polymers substantially similar to these, and are melt processed to produce a matrix-matrix morphology with mechanical interlocking of the polymer components that is maintained upon cooling. Additives may be provided in one or both adhesive components to improve the cohesive strength of the adhesive formed by the mechanical interlocking.

Abstract: A fluid actuator having a piston, a pair of springs, a pair of cams, and a pair of cam followers mounted in a housing. A normally open valve is coupled to the actuator output shaft for actuation. When fluid pressure is applied to the piston, the springs are compressed, and the cam followers are moved down to permit the cams to rotate away from each other, thereby reducing the force on the actuator output shaft and permitting the valve to open. When fluid pressure is removed from the piston, the springs expand pushing the piston and the cam followers up, thereby rotating the cams toward each other and forcing the actuator output shaft against the valve stem to close the valve.

Abstract: In an assay, a conjugate of ligand and sac lysing agent is contacted with analyte and binder to produce bound and unbound portions of conjugate. The unbound portion of the conjugate contacts sacs, containing a detectable marker to release the marker as a measure of analyte. The binder and sacs may be placed on different portions of a solid support to provide a solid phase assay.

Abstract: Test device and assay for determining analyte wherein tracer and sample may be simultaneously applied to different absorbent material portions both in capillary flow communication with an absorbent material portion having a binder supported thereon in a manner whereby sample contacts binder, prior to any substantial contact between sample and tracer or tracer and binder.

Abstract: A padlock-type security seal including a U-shaped shackle, a pair of reversely bent end portions, and a transparent body portion having a pair of chambers for receiving the bent end portions. The chambers each have a locking groove therein for receiving the bent end portions. A frangible tab is mounted adjacent one of the locking grooves. Attempts to pick the seal by deforming the shackle will result in breaking the tab. The tab, after breaking, will protrude into the chamber where it can be viewed through the transparent body to indicated tampering.
