Abstract: In some preferred embodiments, a heat shrinkable foamed sheet has a foamed layer (2) constituting a core layer, and a non-foamed layer (3) constituting a surface skin layer integrally formed on the formed layer. The non-foamed layer (3) is less than about 1.55 ?m in maximum surface smoothness measured in accordance with ISO8791-4. Alternatively, by regulating various dimensions of foam cells formed in the foamed layer (2) so as to fall within predetermined ranges, a heat shrinkable foamed sheet excellent in surface smoothness and printing nature can be obtained.

Abstract: A filter silencer with quick disconnect lid has a cylindrical hollow casing, an inlet, a filter within the casing, a spring loaded seal plate beneath the filter, a flange opposite the inlet, and a lid turning to connect to the flange. The inlet admits blower air into the casing generally beneath the spring loaded seal and the air enters the sides of the filter. The air travels upwards through the filter and exits through the lid. Wear pads beneath a locking ring engage the tapered ears upon the lid. The lid has an outlet through which filtered air discharges. The lid has ports for monitoring differential pressure and air temperature while the casing has a port for a pressure relief valve.

A first portion of the gasket is shaped to fit within a groove or recess of the corrugated pipe. A second portion of the gasket extends from the first portion. The second portion is at least partially comprised of permanently lubricated film for facilitating in the connection of the pipes along a single direction.

Abstract: A seal includes an annular hub and an annular sealing projecting outwardly from the hub. The sealing lip includes an inner portion located adjacent the hub and an outer portion spaced from the hub. The outer portion defines a nose. The seal includes a hinge portion formed as a one-piece construction with the hub and the sealing lip, and the hinge portion pivotably interconnects the sealing lip to the hub so that the sealing lip is selectively manually movable to and between: (i) an operative position, where the nose is located axially outward of the second axial end of the hub; and, (ii) a non-operative installation position, where the lip is located axially inward of the second axial end of the hub. The hinge portion biases the sealing lip away from the operative position when the sealing lip is moved to the non-operative position, and the hinge portion biases the sealing lip away from the non-operative position when the sealing lip is moved to the operative position.

Abstract: The present invention relates to a light weight check valve for use in bulk material transfers that incorporates a smooth, generally spherical interior cavity to minimize flow inefficiencies. The check valve is made from two portions: a body portion and a lid assembly which is removably mounted to the body portion. The gate valve, or poppet, is hingedly mounted to the lid assembly. Hence, when the check valve assembly is opened for inspection, by removing the lid assembly, the poppet is removed along with the lid assembly, to allow for easy inspection of the poppet.

An elongated tubular member and method of manufacturing the same, as well as a labeled container are also provided.

Abstract: A mechanical rotary seal that produces a positive drive force so that all components of the seal rotate in unison upon a rotating shaft. The mechanical rotating seal effects a tight fluid seal between a submersible pump housing and a rotating shaft when the mechanical rotary seal is engaged with a stationary seal or element within the submersible pump housing. The mechanical rotary seal comprises a seal housing, a retainer having a seal face for engaging with the stationery seal and a coil spring between the seal housing and the retainer.

Abstract: A process (30) is presented for the post-honing cleaning and lubrication of a cylinder (24) of a reciprocating engine (22) prior to assembly thereof. The process (30) includes cleaning (32) the cylinder (24) with a water-and-wetting-agent solution and with a solvent in an effort to remove contaminants. The process (30) also includes lubricating (40) the cylinder (24) with a penetrating oil, and coating (42) the cylinder (24) with an indicating lubricant (28) formed of a powdered mixture of tungsten disulfide and graphite. The indicating lubricant (28) is configured to change color to assume a specific tint when contaminants have been substantially removed from the cylinder (24), and to refrain from assuming that tint when contaminants have not been substantially removed from the cylinder (24).

Abstract: An improved neck seal having an interior surface being concave throughout and shaped to entirely conform to the circumference of a roll surface of a roll. The concave surface further defines the interior side of an oil-side lip extending upwards from the seal body. A portion of the lips outermost end extends radially downward to form a first stop integral with the lip. A portion of the outermost end of the seal body also extends upward from the top surface thereof to form a second stop integral with the seal body. A v-shaped spring is then disposed in a v-groove defined by the inclined bottom surface of the oil-side lip, and the flat top surface of the seal body. In this manner, the first and second stop retain the spring in a position conducive for a more positive seal contact between the lip of the seal and the roll neck without the use of a garter spring.

Abstract: A multilayer sheet, which is particularly well adapted for use as as a label sleeve on carbonated beverage containers, includes first and second coextruded unfoamed layers of polymer compositions each consisting essentially of polyolefin, polystyrene and a compatibility agent. The polyolefin and polystyrene are in a weight ratio in the range of about 30/70 to 70/30, and the compatibility agent is in the amount of about 5% to 10% by total weight. A pigment in the amount of about 10% to 15% by total weight may be included in one or both of the coextruded layers. The polyolefin preferably is selected from the group consisting of polypropylene, polyethylene and mixtures thereof, and the compatibility agent preferably comprises a styrene-ethylene/butylene-styrene block copolymer. One of the unfoamed layers preferably is thicker and of higher strength than the other layer, while the other layer has a smooth uniform exterior surface.

Abstract: A heat-insulating food container includes an injection-molded container body having a bottom wall, a circumferential wall integrally connected to a periphery of the bottom wall and upwardly extending therefrom for defining an inner space and an upper open end, and vertical ribs vertically extending along the circumferential wall. The circumferential wall includes circumferential wall parts respectively having different diameters and arranged in such a manner as to form the circumferential wall with the diameter thereof decreasing in a stepwise manner as it advances downwardly, thereby forming corresponding stepped portions on an exterior surface and an interior surface thereof.

Abstract: A rotary seal adapted for placement on an associated rotating shaft to inhibit fluid flow between the shaft and an associated housing includes an annular main seal member having a peripheral surface, an inner surface defining a central opening, and first and second transverse faces. One of the transverse faces defines a sealing face adapted for sealingly abutting a transverse surface of the associated shaft in a substantially fluid-tight manner. A resilient annular sealing member circumscribes the main seal member and projects radially outwardly therefrom. The resilient annular sealing member is, thus, adapted to sealingly engage the associated housing and the main seal member to inhibit fluid flow therebetween. The resilient sealing member also rotatably fixes the main seal member to the associated housing. An inner ring member is slidably received in a groove defined in the inner surface of the main seal member.
