Abstract: A conduit system for supporting and clamping a bank of conduits of different diameters in a substantially parallel and spaced apart relationship which requires a minimum number of parts and which can be assembled simply and rapidly. The basic structure is comprised of a plurality of vertically and horizontally interlocking modular units, each consisting of a frame member having at least one side thereof including an arcuate surface corresponding to the outside diameter of a first conduit. The conduit is supported on the arcuate surface of one frame member and clamped thereon by a second, superimposed, interlocking frame member. A unitary generally U-shaped adapter is employed to support a smaller diameter conduit within the system. One end of the adapter includes a snap-on clip to facilitate attachment to an arcuate surface of a frame member and the opposite end comprises a pair of opposed resilient arms for receiving and holding the smaller conduit in a fixed relationship to the arcuate surface.

Abstract: An injection molded end cap for attachment to the terminal end of an extrusion.

The abutting ends between end cap and terminal end of the extrusion may be secured to each other by heat sealing, adhesives, and the like.

Abstract: An improved rotary joint structure for transmitting fluid into and removing condensate from a rotating device, including a stationary housing into which a rotatable sleeve extends. A siphon pipe is positioned concentrically within the rotatable sleeve. At the free end of the rotatable sleeve there is positioned a fixed combination seal and thrust bearing which carries the thrust load of the sleeve. A spherical surface on the fixed bearing engages a corresponding surface on a sleeve flange affixed to the rotatable sleeve to maintain the sleeve in position as it rotates. A second seal unit is provided on the sleeve at the opposite end of the housing, and a compression spring encircles the rotatable sleeve between the two seal units to urge them into engagement with their respective sealing surface. Both the combination seal and thrust bearing unit and the second seal unit can be replaced without removing and disassembling the joint.

Abstract: A method and system for tensioning and applying a foam core tape having pressure sensitive adhesive faces to a body side molding. The method is effected to obtain the necessary stretch in the foam core tape to coordinate with any dimensional changes which may occur in the body side moldings to which it is bonded. The system includes a tensioning roll disposed between a supply roll and the point of application of the tape to the body side molding. The peripheral surface of the tensioning roll frictionally engages the foam tape and the rotation of the tensioning roll is controlled by suitable braking mechanism to effect a desired stretch in the tape prior to its application to the body molding.

Abstract: A system for anchoring the conduit spacers of a utility duct bank in a fixed position within a trench during encasement or burial of the duct bank. The conduit spacers comprise components having mating bosses by means of which they can be horizontally and vertically interlocked. A holder interfits with the horizontal or side attachment bosses and includes a vertical guide opening for receiving a length of steel reinforcing bar or other elongated member. The length of reinforcing bar is inserted through at least one, and preferably two or more aligned and driven into the earth forming the floor of the trench, and the top portion of the bar is secured as by being bent over the upper holder to prevent the duct bank from shifting or floating upwardly as when concrete is poured around it. The shape of the holders is such that a tapered notch is created between the conduit spacer and holder fitted thereto for receiving a horizontally extending reinforcing rod to provide added strength to the duct bank.

Abstract: The present invention concerns an apparatus and process for producing an improved extruded plastic material product which consists of an inner foamed thermoplastic cellular core and an outer non-porous thermoplastic skin extending along at least one side of the core. In the process, a foamable thermoplastic material is extruded through a first die outlet to produce a foamed thermoplastic material. After exiting the die outlet, a film of non-porous thermoplastic material is applied along at least one side of extruded foamed material. Next, the extruded foamed material and the non-porous film is fed through a forming die which shapes and seals the materials into the desired cross-sectional shape.

Abstract: A method for utilizing a unique multi-chambered conduit insert for converting a single chambered conduit into a multi-chambered conduit. In particular, the conduit insert includes a plurality of cooperating longitudinally extending walls defining a plurality of parallel spaced apart coextensive chambers. The outer wall of each chamber which is adjacent the inner supporting surface of the single chambered conduit has a configuration wherein, if the outer wall contacts the inner conduit surface when the conduit insert is inserted within the conduit, such contact is line-to-line contact. This construction results in minimal contact of the insert with the interior wall of the existing conduit and enables the multi-chambered conduit insert to be fed into the existing conduit with the expenditure of minimal energy. In the method of the present invention, two individual conduit inserts are placed in back-to-back relationship to form an insert assembly which is subsequently inserted into the single chambered conduit.

Abstract: The present invention relates to an inspection apparatus for detecting the surface distortion in a sheet of material such as a sheet of glass, for example, and for indicating whether the level of distortion detected in the inspected sheet is unacceptable. The inspection apparatus includes a light source mounted to direct a first beam of light toward one surface of the sheet at an oblique angle of incidence to cause a second beam of light to be reflected therefrom. A light detector is mounted to receive the reflected beam and is responsive to a light pattern produced by the reflected beam of light for generating an output signal representing the width of the light pattern. The width of the light pattern is a function of the surface distortion of the portion of the surface from which the beam is reflected. A control circuit is responsive to the detector output signals for generating an actual distortion signal representing the amount of surface distortion in the inspected portion of the surface.

Abstract: The present invention relates to a multi-chambered conduit insert which can be utilized to convert a single chambered conduit into a multi-chambered conduit. In particular, the conduit insert includes a plurality of cooperating longitudinally extending walls having curved outer surface portions and defining a plurality of parallel spaced apart coextensive chambers. When the conduit insert is inserted within the single chambered conduit, the curved outer surface portions of at least one of the chambers in the lower half of the insert is in line-to-line contact with the adjacent inner supporting surface of the single chambered duct, thus causing only minimal contact with the interior wall of the existing conduit and enabling the multi-chambered conduit insert to be fed into the existing conduit with the expenditure of minimal energy.

A gear-drive mechanism operatively connected to the screwjacks rotate the screwjacks in unison.

Abstract: The present invention relates to a mold structure for forming a polymeric gasket around a predetermined portion of a sheet of transparent material such as glass, for example. The mold structure includes two cooperating mold sections for defining a chamber for receiving the transparent sheet.
