An improved base shoe for use with panel installation removal systems. The improved base shoe includes dovetail grooves for use with a safety-seal and a weather seal, wherein the safety-seal and weather seal must be installed prior to installing a glass panel. The improved base shoe features a recess for use with taper plates having a continuous projection along an upper surface. The base shoe and taper plates are configured so as to provide a prying surface between the projection on the taper plates and a wall of the base shoe.

An electrically isolating gasket is disclosed wherein a coating layer is disposed on at least one conductive surface, and in some embodiments, on all surfaces or at least all of the conductive surfaces. The electrically isolating gasket includes a core gasket component, a ring seal component, and a non-conductive inner seal component. The coating layer can be, for example, polyimide, polyamide, ceramic, and aluminum oxide.

In solenoid valve provided with: a valve case that has an annular collar expanding in a radial direction of an opening, which is opened at an axial end surface, and accommodates a valve body inside; and an annular seal member mounted in an annular recessed groove provided on one axial end surface of the collar of the valve case, the collar includes a through-hole penetrating the collar in an axial direction, and a connecting portion connecting the through-hole and the annular recessed groove, the through-hole has a reduced diameter portion, and the seal member includes an annular portion mounted in the annular recessed groove and a protruding portion protruding at least in the axial direction with respect to the annular portion and penetrating the through-hole, the protruding portion including an enlarged diameter portion having an outer diameter ωD1 (>ωd2) larger than an inner diameter ωd2 of the reduced diameter portion of the through-hole.

Disclosed is a waterproof substrate, including: two mounting surfaces disposed facing away from each other; and at least one waterproof protrusion provided on at least one of the two mounting surfaces and including: a protrusion body connected with the mounting surface, and one end of the protrusion body away from the waterproof substrate includes a connecting end surface; and at least two waterproof ribs, and each of the waterproof ribs is provided on the connecting end surface respectively and is gradually inclined outwardly in a direction away from the connecting end surface respectively.

An insert with a hole running through its center for a fastening connector to pass through. The self-centering sealing insert in FIG. 1a, has a central hole (pos. 1.1) running through its inner part for the passage of a fastener. Its body is made in the form of two identical truncated cones (pos.1.2 and pos.1.3) combined with their large bases in the center of the body, which tapers to the edges where a central hole is formed; and the truncated cone is part of a right circular cone formed by rotating a rectangular trapezoid around its side with a height of H (FIG. 1c) perpendicular to the bases of the trapezoid; while the radius of the larger base R1.2 is greater than the radius of the smaller base R1.1 so that the value of the angle β, which is formed by the plane between the two bases of the truncated cones and their tapering sides, is in the range from 1 to 89.9 degrees, preferably from 25 to 65, more preferably from 40 to 50, and most preferably at an angle of 45 degrees; while the radius of the larger base R1.2 and the radius of the smaller base R1.1 refers to the height of the lateral side of the rectangular trapezoid, so that the height H is less than or equal to the value of the difference between the radius of the larger base R1.2 and the radius of the smaller base R1.1.

A thermal processing apparatus (20) includes a spiral conveyor system (22) configured into an ascending spiral stack (26). An inner mezzanine (40) is disposed within the circular interior of the stack (26) and an exterior mezzanine (42) encircles the spiral stack. The mezzanines divide the processing chamber (32) into a plurality of processing zones. A sealing system (90) seals the interior mezzanine (40) relative to the spiral stack (26). A sealing system (130) seals the outer mezzanine (42) relative to the exterior of the spiral stack, and a seal system (132) seals the outer mezzanine relative to the walls (56, 58) of the housing, thereby to limit the leakage of the processing fluid between the mezzanines and the spiral stack (26) and housing walls so that as much as the thermal processing medium is possible is forced through the spiral stack for processing work products carried on the conveyor system (22).

A method of installing an insert in a body is provided, including advancing an insert into a bore of the body bounded by a lip so that a round seal of the insert passes the lip with a clearance therebetween, and so the insert first engages the body with a contact rim rather than the round seal. Accordingly, the round seal is not compromised to self-center the insert in the bore. The bore can include a shoulder distal from the lip. The round seal, which optionally can be an O-ring, can sealingly engage the shoulder and a secondary bore after the insert is self-centered in the bore. The round seal can be advanced farther into the body so another contact rim engages the shoulder. The insert can be heated so components of the body melt and fuse to parts of the insert during installation. A related system is provided.

A gasket for a plate heat exchanger, wherein the gasket includes a body in the form of a loop for fitting to a plate of the plate heat exchanger. The body includes one or more peripheral connection areas spaced along at least one side of the loop, and a plurality of tabs for securing the gasket in position on the plate. Each tab is discrete from the body, and each tab includes a connection which is receivable by or engageable with one of the connection areas to connect the tabs and body together.

Embodiments of the present invention provide a pre-combustion chamber assembly, comprising (a) a body, having a cylindrical end portion having a step-wise increase in diameter forming a sealing surface for sealing to an engine; (b) a tip, with a hollow shaft in fluid communication with a combustion region of the tip, where the shaft has a first shaft diameter that allows the shaft to be slid over a portion of the body; (c) a gasket mounted about the body and resting against the sealing surface, wherein the gasket comprises a wire wound washer.

A sealing member for a powder slush molding apparatus includes an elastomeric main body comprising a head portion, an anchor portion, and a neck portion extending between and joining the head portion and the anchor portion. The head portion of the sealing member defines at least one interior channel that is centered on a midline of the elastomeric main body and which has a polygonal sectional shape. The polygonal sectional shape of the at least one interior channel, and its location on the midline, permits the head portion of the sealing member to attain a measure of compressibility that helps limit the force needed to compress the head portion without rendering the sealing member too flexible that it cannot adequately retain its shape. The sealing member is useful in establishing a seal between a shell and a powder box of a powder slush molding apparatus.
