Abstract: A seal structure for placement at the joint between first and second cowl sections forms a seal between the cowl sections at two distinct locations. A resilient seal is formed at each sealing location, with one of the resilient seals being provided by a composite sealing construction. A flexible sealing strip for placement at the joint includes portions which form a pocket disposed between facing surfaces of the cowl sections, and a resilient cord placed within the pocket around the periphery of the joint. The pocket forming portions of the sealing strip can be moved to an open position so as to allow the strip to be satisfactorily stapled or otherwise connected to one of the cowl sections, as well as to allow placement of the cord within the pocket. The second resilient seal is provided by an enclosed air space disposed between another set of facing surfaces provided on the cowl sections.

Abstract: A message-carrying, antenna-mountable windsock allows a car owner to express a thought or concept. The windsock is tubular, preferably tapered, and is attached to the antenna of an automobile via holes in the top and bottom sides of the front end of the windsock. Several holes are provided for enabling the windsock to be horizontally positioned regardless of the angle of the antenna. The windsock is held in position on the antenna by a segment of slit rubber tubing, plastic twist ties, or both, positioned on the part of the antenna's shaft inside the windsock. A message, advertising, etc. is printed on the side of the windsock. The sock is very inexpensive to produce and the stock is easy to attach and remove.

Abstract: A seal assembly for a rotating shaft includes an annular seal washer of flexible, fluid-impermeable material and capable of undergoing creep, i.e., slow movement or change in size while under stress. A helical garter spring encircles the washer and stresses it by biasing it radially inwardly. An annular housing of two interlocking members cooperate to enclose the spring and an O-ring which cooperates with the housing to resiliently clamp the washer to inhibit movement axially and circumferentially of the shaft, while accommodating radial creep under the urging of the spring. Inwardly struck tabs in the housing may engage the spring to inhibit circumferential movement thereof. In one embodiment, one of the housing members has circumferentially spaced-apart fingers adapted to be interleaved with the tabs of a fixture to facilitate assembly of the apparatus.

Abstract: A steel laminate gasket of the invention is situated for an internal combustion engine having at least one hole therein. The gasket comprises a first plate having at least one first hole corresponding to the hole of the engine and at least one first bead situated around the first hole, a second plate situated under the first plate, and a support device. The size of the support device is smaller than that of the first bead. The support device is situated beneath the first bead so that when the gasket is tightened, the support device abuts against and supports the first bead. As a result, the gasket can provide strong, even and wide sealing pressure.

Abstract: A gasket seal for use in ultra-high vacuum systems is provided which comprises two rigid flanges disposed in opposite facing relation to each other, the flanges having a gasket inserted therebetween when the gasket seal is made up into its operating position. The gasket has at least one integral handle in the form of at least one wire adapted to extend from the gasket through a leak check groove of one of the flanges, the wire being used to handle the gasket and to clip the gasket to one of the flanges where desired prior to making up the joint. The wire may also be used as a conductor of heat to deliver heat to the portion of the system under vacuum, and the gasket may further have feedthrough means or a section having mounting holes for support structures extending inwardly of the flanges.

Abstract: A seal for a hydraulic cylinder is disclosed and includes a static seal element and a dynamic seal element, the dynamic seal element having a continuous, annular form, the form being inscribable in an annular section of a truncated cone and having an anti-extrusion portion at either end thereof.

Abstract: A radial seal for use in connection with a cylindrical rotatable member passing through a stationary member which includes a circular floating shoe mounted to the stationary member and surrounding the rotatable member in order to accommodate axial, lateral and rotational movement of the rotatable member while still providing an effective seal.

Abstract: A dust excluder (12) for a seal assembly (10) such as utilized with a vehicle air conditioning compressor is disclosed as having an annular inner portion (36) that mounts on a rotatable compressor shaft (20) and as including an outer portion (38) that seals with an annular support (24) of the seal assembly axially outward from a shaft seal (30) in a manner that excludes dust to prevent seal abrasion without increased heating of the compressor shaft. The inner portion (36) of the dust excluder is preferably embodied by an annular body (56) having opposite axial ends (58,60) and the outer portion (38) is preferably embodied by a sealing section (62) having a disc (64) extending outwardly from the annular body (56) and by a sealing lip (66) extending outwardly from the disc for slidable engagement with the annular support (24). The sealing lip (66) is preferably inclined and has an edge junction that provides an annular line contact (68) with the annular support (24).

Abstract: An improved liquid seal for a stern drive bell housing gear shift shaft. The upper end of the gear shift shaft is positioned within the designed water free drive shaft gimbal passageway in the bell housing while the majority of the remaining portion of the gear shift shaft extends through the adjacent exhaust passageway in the bell housing which is designed to have sea water passing therethrough. The seal is disposed within an aperture in the partition between the gimbal and exhaust passageways through and within which the gear shift shaft is held for operable rotation. The seal includes a rigid bushing having an upper and a lower portion, the upper portion adapted for forced watertight fit within the bell housing partition aperture. The lower portion of the seal is enlarged and adapted to sealably receive at least one replaceable enlarged annular-shaped water and oil seal which operably engages against the gear shift shaft.

Abstract: An annular shaft seal including a continuous lip sealing element for sealing against oil flow between a bore and a shaft extending through the bore includes a convoluted elastomeric flexible section which connects the sealing element with a rigid case support. The flexible section is defined by a plurality of annuli, wherein each adjoining pair of annuli defines a reverse bend therebetween. One or more of the reverse bends is reinforced with a relatively non-elastic material, preferably plastic, which is integrally molded thereinto, and provides a torsional rigidity while permitting radial flexibility. This provides a closer following of the lip seal element on the shaft under conditions of extreme runout wherein the lip seal element would otherwise become dynamically distorted.

Abstract: A metallic spring member 30 cooperates with grooves 32, 34 disposed in pressure containing members 10, 12. The spring member 30 has an E-shaped cross section and is compressed both horizontally and vertically when the members 10, 12 are fully engaged. The seal is self-energizing under normal operating conditions and able to accommodate small, but significant relative motion between the pressure containing members 10, 12 during conditions of abnormally high and unevenly distributed temperature.
