Abstract: A modular apparatus for extruding a pressurized molten thermoplastic material comprising a service block module which defines a first passage for the material and includes front and rear surfaces. A removable gun module is attachable to the front surface of the service block module. A combination filter-control valve assembly is contained within the service block module. The assembly communicates with the first passage so as to filter and control the flow of material to the gun module.

Abstract: A rigid hose cuff for a heated hose for transporting molten hot melt adhesive. The cuff comprises a cylindrical body made of a rigid material. The cylindrical body is positioned on the hose adjacent a hose end having a fitting attached thereto. A two-piece collar is positioned on and then is connected to the cylindrical body. The collar engages the fitting so as to prevent relative rotational movement between the hose cuff and the hose.

Abstract: A tamper-evident container and a method for making the same. The container includes at least one open end with integral flaps adjacent the open end. A thermoplastic material is applied to one flap with the other flap folded over onto the one flap. The flaps are thus sealed together with a thermoplastic material. A temperature-sensitive indicator is applied to the closed end so that the indicator visually indicates whether an excessive amount of heat has been applied to the seal of thermoplastic material.

Abstract: A right angle nozzle assembly for use with a fluid dispenser. The assembly includes a nozzle body having a nozzle tip disposed at a right angle to the longitudinal axis of the body. The body defines an integral distal projection that projects past the tip so as to protect the tip. The projection includes an alignment slot receivable of a tool so that the direction of the dispensation can be visually perceived as well as selectively set.

Abstract: A fluid heater for heating high solids fluids having a solids content approximately 50% or higher, which fluids are applied to a substrate by a coating process, includes a cylindrical body of thermally conductive material having a helical channel formed on the outer periphery thereof and including a section member dividing the channel into a pair of side-by-side passages, each having a cross-sectional area of about 0.119 square inches and a length of about 80 inches. A common input plenum identical in size to the cross-sectional area of the channel communicates with one end of each of the passages and the other end of the passages are connected to a common output plenum. An electric heating element is located in said body along the central axis thereof and is sized to produce a watt density on the surface of said passages in the range of 7.5 to 8.0 watts per square inch whereby the high solids fluids are heated for ease in application with a minimum loss of fluid pressure upon passing through the heater.

Abstract: A support for a flexible heated dispensing hose comprising a hollow cylinder having opposite ends. A bracket attaches the cylinder to the dispenser. A helical spring is contained within the cylinder and extends beyond the opposite ends thereof. The hose is supported by the spring and cylinder so that the hose is free to move from side to side, the hose is prevented from kinking, abrasion of the hose against the cylindrical member is reduced, and optimum ventilation of the hose is provided.

Abstract: A retainable closure for selectively atmospherically isolating a passageway in a fitting wherein the passageway terminates in an orifice. The closure comprises a retainer connected to the fitting. An elongate elastic cover is secured to the retainer. The cover is selectively positionable between a first position wherein the cover engages the orifice so as to atmospherically isolate the passageway, and a second position wherein the cover is disengaged from the orifice so as to allow unobstructed passage therepast.

Abstract: A controller for uniformly dispensing fluid onto a substrate in response to movement between the dispensing unit and the substrate has a sensor which senses the rate of relative movement and supplies a signal reflective of the movement to an operation device which in turn generates and supplies a control signal to a regulator. The regulator is positioned in the fluid dispensing system and regulates the flow rate of the fluid to the dispensing unit so that the substrate receives a substantially uniform fluid coating per unit length. The operation device receives the signal from the sensing means and computes the rate of relative movement.

Abstract: An extended nip shoe for a press section in a papermaking machine distributes a compressive force to an inrunning compliant transport system advancing a web of paper. The shoe introduces and maintains a film of lubricant throughout the extended nip shoe-compliant transport system interface. Similarly, release of the compressive force is gradual to eliminate points of high unit loads on the compliant transport system and paper web.

Abstract: A roll having an elastomeric cover for engaging another roll to form a couple, said cover having circumferential grooves and comprising an anisotropic material which has a greater modulus of elasticity as measured in the transverse direction than in the circumferential direction to prevent closing of the grooves by transverse flow of rubber in the nip area.

Abstract: A press section for extracting water from a continuous traveling web in which the web is sandwiched between a traveling belt and a drum. The belt is wrapped partially about the drum and a pressure shoe exerts pressure on the belt in the wrap area to press the web. The laterally outer ends of the drum are relieved to provide a reduced diameter portion in the areas extending laterally outwardly of the pressure shoe.

Abstract: An apparatus for mounting and permitting swivel movement through 360.degree. of an engine driven aerodynamic propeller type of propulsion and steering unit such as used on aquatic craft. The engine and propeller are mounted on a pedestal which in turn is mounted to swivel about an axis substantially normal to the boat deck. The engine throttle cable is connected to an unique universal coupling which permits axially reciprocal movement of the throttle cable, and thereby control of the engine, independent of either the position of the engine or the extent of the rotational movement of the propulsion unit relative to the platform on which it is mounted. The propeller is connected to the engine by a centrifugal clutch to permit the engine to be started and idled without operating as a propulsion device.

Abstract: A raker boom supports a plurality of independently driven and mounted rotatable raker wheels which are applied to the face of a pile of material to dislodge and move the material downwardly toward a bucket wheel and conveyor for gathering and conveying the material to a remote location for processing. The boom is capable of rotating in a vertical plane so that the raker wheels can contact and remove all of the material through the depth of a pile. By operating the raker wheels individually and mounting them independently, the raker apparatus can travel and apply the individual raker wheels over the surface of a pile of material regardless of its contour. The wheels can break up lumps of material, especially on the surface of the pile, and mix the material with other material within the pile. In one configuration of the preferred embodiment, a pair of opposed raker wheel booms are mounted on a raker carriage which itself is mounted for reciprocal travel on a raker truss.

Abstract: Apparatus for feeding material from a large supply of such material wherein a screw is horizontally disposed at the bottom of the piled material. Both ends of the screw are mounted in a trunnion bracket in a traversing carriage which supports the screw and allows axial movement relative to the trunnion carriages and skewing movement in a horizontal plane. A drive motor is mounted directly to the screw and is in turn supported in a trunnion bracket. Separate drive motors power the carriage at both ends of the screw. Proximity switches are disposed in conjunction with the front trunnion bracket to both limit the degree of skewing and to control the traversing motors on the carriages to keep the apparatus aligned and reciprocating beneath the piled material.
