Abstract: A one-piece sheet metal nut particularly adapted to be clamped against a plastic workpiece to accommodate any cold flow of the plastic under the clamping force without appreciably reducing the tension in the joint thus created. The nut incorporates an inner internally threaded body integrally connected by an upper top wall to an outer body. The lower region of the outer body is frustoconical and adapted to engage a mating frustoconical surface in the plastic with the uppermost extremities of the nut incorporating an axially compressible spring means permitting portions of the sheet metal nut to move longitudinally relative to one another, which, in conjunction with the broad surface contact between frustoconical surfaces, overcomes any cold flow effect.

Abstract: A machine which may be used to either check or to machine the profile of an orbiting star gear for a gerotor type of fluid motor or pump is disclosed. The profile of a star gear is traced due to the interaction of a slide that carries a sensor, or a machining tool, in a back and forth direction toward and away from the star gear and in a second direction transverse to this back and forth direction with respect to a frame member. The slide is driven by an eccentric disc, at a rate which is determined in accordance with the number of teeth on the specific star gear in question. The combined motion of the star gear and the two slides causes the sensor, or the machining tool, to trace out the profile of the desired star gear for the purpose of either checking its profile, or of machining a new gear. A spring member is connected to the frame member to allow the frame member to move in a transverse direction but without rotation.

Abstract: A multipackaging method and apparatus for multipackaging containers with a stretchable plastics material device or carrier that essentially uses the containers as the carrier applicating elements.

Abstract: A device adapted to be adhesively secured to a primary work surface to facilitate the securement of a secondary workpiece to said primary work surface. The device will include a plate-like base with a layer of heat activable adhesive on its undersurface and a pair of parallel side edge flanges extending upwardly from the base serving as a means to align the device beneath the legs of a U-shaped induction heating core and a spacing between the end faces of the legs of the core and the adhesive layer.

Abstract: An electrical capacitor is formed which relies on a thin dielectric layer which is metallized on both sides to provide electrode areas to provide the major part of the capacitance of the capacitor. An unmetallized margin area runs along one side of the dielectric layer along one longitudinal edge of the dielectric layer and an unmetallized margin area runs along the other side of the dielectric layer along the opposite longitudinal edge dimension of the dielectric layer. A pleated capacitor section is formed by pleating, or folding, the dielectric layer along its longitudinal dimension. This pleated capacitor segment is incorporated into an initial portion of the capacitor formed of two metal foil electrodes and a separating dielectric layer which are wound about the leads of the capacitor.

Abstract: An improved positional transducer is disclosed which utilizes an elongated, hollow, cylindrical tube of a magnetically saturable material, a sense wire that runs through the tube parallel to its elongated axis and a pair of elongated, generally rectangular shaped magnets of opposite polarity which are closely positioned adjacent diametrically opposite exterior portions of the tube. As the magnets move over in the tube, they provide substantially complete saturation of the tube in the portion over which they extend while the remaining portion of the tube remains unsaturated thereby giving a linear indication of the position of the magnets with respect to the tube. In the improved version, shown herein, adjustments of the electrical slope (volts/inches of travel) are achieved by a slot cut through the wall of the tube in the direction of the tube's length.
