Abstract: Non-conjugated dienes are reacted with phenolic compounds in the presence of a Friedel-Crafts catalyst to produce poly(phenol/diene) copolymer resin having repeating alternate phenol and diene units, a number average molecular weight of 600-5000 and a glass transition temperature of 100.degree.-220.degree.C. The resin, and its partially or fully hydrogenated counterpart, can be blended with various rubbery polymers to provide adhesive compositions having improved adhesive tack.

Abstract: The disclosed compounds are adducts of imidazole or derivatives thereof and sulfur dioxide. The adducts are apparently of the Lewis acid-Lewis base type, and are useful as latent curing agents for epoxide resins. The adducts are prepared by interacting the imidazole and sulfur dioxide under anhydrous conditions. Equimolar imidazole-SO.sub.2 adducts can serve as a source of sulfur dioxide at room temperature.

Abstract: A device for measuring transport torques and tensions of magnetic video tape record/reproduce units includes a cartridge with a housing that is preferably similar to that of a normal video tape cartridge. Two reels are rotatably disposed in the housing and are provided with torque and tension measuring components in order that measurement of the torque and tensions of a record/reproduce unit may be readily performed upon loading the cartridge in the unit.

Abstract: An audio-visual system for providing correlated audio and visual presentations from audio-visual slides in a sequence corresponding to a branched learning format. Upon an operator selecting a presented response choice, a projected program containing first indicia providing a binary number indicating the number of steps and second indicia indicating the direction which the slide magazine should be stepped to be in position for presenting the next slide, is sensed and the binary number is stored in a register. The magazine is stepped in the indicated direction; and the number of steps taken are counted and compared to the binary number stored in the register. When the compared counts are equal, the stepping of the magazine is stopped.

Abstract: A package for endless belts to avoid kinking and cracking of the belts including a first core having an axial slot to receive axially within said core one end of a nest of belts. The belts are wound around said first core and a second core is disposed in the opposite end of the belts. A third core inserted in the nest of belts and disposed in the loop within the first core will further restrict kinking of the belts.

Abstract: This invention involves an imaging process in which a light image is projected onto a photosensitive medium having a layer capable upon light exposure of directly generating nuclei of a metal more noble than silver, such as palladium, which metal is catalytic to the electroless deposition of a non-noble metal, and thereafter selectively providing non-noble free metal onto the noble metal nuclei by electroless deposition, thereby providing a visible print of the original light image. The photosensitive layer in such media may comprise a compound of a metal more noble than silver and a photosensitive composition which can generate upon light exposure a reducing agent for said noble metal. In another embodiment, the photosensitive layer may contain a photoreducible metal salt which, upon light exposure, generates nuclei of a metal more noble than silver.

Abstract: A sensing device that may be employed as a thermal or stress sensor includes in one embodiment a pair of poled electret layers as sensing mediums for detecting variations in the ambient temperature of the sensor. The electret layers of such embodiment have pyroelectric and piezoelectric properties, but only pyroelectrically produced electrical signals are used for sensing and piezoelectrically produced signals due to bending are effectively negated. In another embodiment, the electret layers are used as stress sensors whereby piezoelectrically produced electrical signals are sensed and pyroelectric signals are operatively canceled.

Abstract: A device used during fusion butt-welding between the ends of tubes to form a backing for the weld inside the tubes. The device comprises a thin flexible metal support strip having end portions which are overlapped to provide an arcuate outer peripheral surface, means guiding the overlapping end portions for relative longitudinal sliding movement to change the peripheral circumference of the support strip, and means for biasing the end portions in a direction to increase the peripheral circumference of the device. For use, the circumference of the support strip is decreased in opposition to the biasing means, and a backing strip of refractory material is secured on the periphery of the support strip. Next the device is positioned with the backing strip adjacent the inner surfaces of and bridging the ends of the tubes to be welded. The device is activated so that the biasing for the support strip will press the backing strip into engagement with the tubes, and the tubes are ready for welding.

Abstract: A multipurpose apparatus is useful in either prefiltering ions or in forming ions from residual gases, prior to the analysis of the prefiltered or formed ions in a quadrupole type mass spectrometer. The apparatus includes a cylindrical grid, an annular entrance aperture wherein a center circular baffle has a unidimensional electrode extending along the axis of the grid, and a circular exit aperture, the axis of the grid being in line with the axis of a quadrupole type mass analyzer. The application of appropriate potentials to these members allows only low energy ions to pass therethrough and into the quadrupole analyzer. High energy ions or neutral particles having an axial trajectory are blocked by the baffle, while divergent high energy charged particles are insufficiently deflected and hence do not pass through the exit aperture. The apparatus further includes a filament positioned outside the grid, which, when energized, emits electrons.

Abstract: A system providing an improved inflatable cushion of the type comprising two films of a thermoplastic fused together to provide a plurality of inflatable chambers between the films, with each chamber communicating with a central inlet opening through an inlet passageway; and an improved device for filling and sealing such a cushion. The inlet opening for the cushion extends through only one of the films, and the device has a nozzle which directs air into the opening against the portion of the other film which extends across the opening, so that the air will be evenly deflected through the inlet passageways to simultaneously inflate all the chambers in the cushion.
