Abstract: A method and apparatus for applying adhesive the edges of a slit tubular body as the tubular body is advanced along a path of travel is provided. The apparatus includes a tape feed for feeding a release tape having an adhesive applied to a surface thereof, a cutting blade for forming a slit having opposing edges in the tubular body such that the cutting blade is interposed between the opposing edges, and a housing member positioned along the path of travel. The housing member is positioned for directing the release tape along the exterior surface of the housing member in a line parallel to the path of travel of the tubular body such that the adhesive is applied to the at least one of the opposing edges of the slit. The housing member is further positioned for covering at least a portion of the cutting blade and separating at least one of the edges of the slit from the cutting blade to reduce frictional engagement of the cutting blade with the tubular body.

Abstract: This invention relates to a hot melt adhesive composition in pellet form. The hot melt adhesive composition is pressure sensitive, having a storage modulus, G′, at 25° C., of less than about 5×106 dynes/cm2. The pellets are coated with a pelletizing aid on the surface at a concentration preferably ranging from about 1 wt-% to about 30 wt-%. The pelletizing aid is a hot melt adhesive component or a material which does not substantially adversely affect the adhesive properties.

C., of less than about 5.times.10.sup.6 dynes/cm.sup.2. The pellets are coated with a pelletizing aid on the surface at a concentration preferably ranging from about 1 wt-% to about 30 wt-%. The pelletizing aid is a hot melt adhesive component or a material which does not substantially adversely affect the adhesive properties. The pellets are free-flowing and have a substantially tack-free surface.

Abstract: Bendable foam-covered rod-like articles and a method and apparatus for their production are described. The method involves feeding an adhesive coated flexible core to an extruder, which in turn extrudes a low density, closed cell foam sheath about the core. The core and sheath composite is then cut into rod-like elements of predetermined length. Each of the rod-like elements is then restrained at a position spaced inwardly from one its ends, and an orificed plate and an element end are axially pressed together such that the core extends through the orifice in the plate and the foam sheath is compressed. The excess core extending through the plate orifice is then cut, and the pressure between the plate and the element is released, such that the foam sheath returns to its original condition, thereby producing a composite in which the core end is recessed into the foam sheath end. The end of the element is finished by sealing, preferably through the application of a hot brand.

Abstract: A polymeric resin composition comprising a polymeric resin in particulate form coated with an additive agent adhered to the surfaces of the resin particles by a coating of thermoplastic adhesive binder between the particles and the agent.

Abstract: A chair has four legs. Pairs of legs are connected by a crossbar to form two leg assemblies. Both legs assemblies are in turn connected by a pre-torqued resilient brace, which is joined to each leg assembly by a wedge joint. The torque in the brace tends to hold the joint together.

Abstract: An apparatus and method for measuring the temperature of a viscous material flow by traversing at least a portion of the flow stream are provided. The apparatus includes an elongated temperature probe which is linearly translated by a motor which has a position sensing means operatively connected thereto for determining the relative position of the probe during movement thereof. A remote control and indicator is electrically connected to the temperature probe for selectively actuating the probe and providing temperature and corresponding position data relating to movement thereof.

Abstract: An elongate lightweight and readily bendable rod-like article and method of making, wherein the article is adapted to be used for a variety of purposes such as a hair curling rod or wrist bracelet. The article comprises a low density and continuous foam body of closed cell foam, a pliable metallic core extending throughout the length of the body and serving to resiliently maintain the body in any desired bent configuration, adhesive surrounding the metallic core throughout the length thereof and bonding the metallic core to the body so that the body and metallic core are unitized and bend together, the adhesive also serving as a corrosion resistant protective coating on the metallic core, and end caps sealing opposite ends of the body and providing a protective shield for opposite ends of the metallic core.

Abstract: An apparatus for accurately metering a viscous material is provided. The apparatus includes an extruder having a drive means, and a gear pump, with the extruder drivingly connected to the gear pump so as to obviate the need for a secondary power system. Three different embodiments of the invention are set forth.

Abstract: Significantly enhanced bending characteristics are provided in a coaxial cable by reducing the stiffness of the tubular sheath in relation to the stiffness of the core. The cable comprises a core including at least one inner conductor and a low loss dielectric surrounding the inner conductor, and an electrically and mechanically continuous tubular metallic sheath closely surrounding the core and being adhesively bonded thereto, the ratio of the stiffness of the core to the stiffness of the tubular sheath being greater than 5.

Abstract: A plastic extrusion apparatus is provided which includes a gear pump for accurately metering the plastic through a die. The apparatus is adapted to process highly viscous plastic material under high temperature and pressure conditions, and the gear pump includes a non-leaking and substantially frictionless seal for the drive shaft. The seal comprises a sleeve surrounding the shaft, and a shallow helical channel formed in the bore of the sleeve, with the helical channel being of a hand such that forward rotation of the shaft results in the plastic which enters the clearance between the shaft and sleeve to be effectively pumped back toward the interior of the housing.
