A label in accordance with the present invention includes a base having a transparent window and an adjacent frame at least substantially surrounding the window, the frame being at least somewhat thicker than the window; a locating projection on the base for repeatably positioning an indicia bearing insert at least partially within the window; alignment holes on the frame; a cover having a transparent window portion and an adjacent frame portion at least substantially surrounding the window port...

The invention provides sealing members for a chain. A first pair of sealing members is provided for each end of a bushing. The sealing members of the first pair respectively surround the ends of the bushing and are housed between inner sidebar portions and the outer sidebar portions of the chain. A second pair of sealing members seals rollers surrounding the bushings.

This invention provides a sealed fastener that includes a housing and a nut assembly, the housing having a base and a receptacle extending beyond the base on one side, an annular seal being positioned on the opposite side of the base and engaged by a flange of the receptacle which holds the receptacle to the base. The nut assembly includes a threaded member within the receptacle and a sleeve extending through an opening into the base and beyond the opposite side of the base. The sleeve is bendab...

A shaft sealing precluding fluid from moving in a direction longitudinally of the shaft. At the same time the shaft sealing allows a motion of the shaft in axial direction, an inclination of the shaft, and may also allow a rotary motion of the shaft relative to its sealing means. The sealing means is a rolling diaphragm including a clamping flange on one end of the rolling wall thereof. The other end of the rolling diaphragm is provided with a cylindrical elastomeric member having a projection c...

A stave for a tub has opposite elongate edges formed with formations each having a section transverse to the stave including an arcuate portion, and a rabbet for receiving a floor of the tub extending between the edges. The formations on each stave are desirably complementary, but need not be. Staves placed in edge-to-edge relation define a tub wall which can conform to an arbitrary shape and size. A tub is formed by a plurality of staves, an appropriately shaped floor, and bands extending aroun...

An electrical connector is disclosed of the type for sealably protecting an electrical splice particularly for buried wires. The connector has a shell for containing the spliced wires to be protected. The shell further contains a volumetrically collapsable container filled with a viscous sealant material. A closure cap is closed compressibly over the container, collapsing the same and expelling and distributing the sealant throughout the connector shell.

A sealed connection for two cylindrical members includes semi-cylindrical connector sections sized to fit about the members, to bridge the joint between the members, and to be retained in position. An over-center flexing seal is also provided between two such members, as for example pipe members.

A sealed terminal of invention is used for a metal vessel containing water and has improved characteristics such as anticorrosive characteristics, water sealing characteristic and high mechanical strength and insulating characteristic. A terminal conductor of an auxiliary anode is seal-bonded in a terminal opening of the metal vessel with an insulator comprising mica and glassy material and which is softened at a temperature lower than about 900.degree. C. and is plastic deformable under compres...

A sealed assembly of two cooperating movable or stationary parts with a gap separating different-pressure media, which comprises at least one recess formed in one of said parts to accommodate a liquid seal, said recess communicating with said gap, and a polycapillary lock formed as a compressed fine-grained packing accommodated in at least one of said recesses in communicating relationship with said seal, the packing and the parts being constructed from a material resistant to wetting by the sea...
