A jacketed valve in which an annular jacket or ring is received over a wafer-type check valve. The ring includes eight axial bores therethrough spaced at 45.degree. intervals to accommodate flange studs when the jacketed valve is received between a pair of pipe flanges. In one embodiment, the annular ring is split in half along a plane normal to the ring axis.

A self-lubricating, vapor trailing ammunition round including a jacket about the forward portion of the bullet and extending rearwardly about the forward portion of the casing, said jacket comprising an inner layer of plastic lubricous material with a low latent temperature of vaporization and a thin outer layer of hard, dry, frangible material. The jacket seals the annulus between the casing the the bullet. The jacket material about the casing lubricates the chamber of the fire arm on which it ...

Jacketed gasket with at least one of its legs folded over for at the most half of its width, the fold being at a distance from the bend of the jacket which is at least equal to the thickness of the gasket in the non-compressed state. Inserts, such as annular disks, washers, wires of metal and synthetic resin, or other plastic material may be inserted into the fold. The gasket, after compression of its jacketed part has the advantage that no flowing out or squeezing out of the gasket material on ...

A valve for use in a service requiring the valve to be heated or cooled, wherein the chamber for circulation of the heat transfer medium is formed between the outer periphery of the valve body and the inner periphery of a surrounding operating housing. The operating housing carries the valve operator and a valve stem. The valve body is insertable lengthwise into the operating housing and a valve stem carried by the valve body and connected to the valve member is adapted to be connected to the op...

A Jacketed paint pellet (10) comprising a jacket (12) having a paint pellet (14) attached thereto. The jacket (12) includes a body (16) having a trailing end (18) and a leading end (20) with a forward facing mounting surface (22). Ribs 28 project radially outward from the body (16) to support the body within the bore of a gun barrel and to guide and stabilize the jacketed paint pellet (10) in flight. Flange members (30) extend laterally from the ribs (28) for additional support and stability. A ...

A communications cable having superior electrical characteristics and meeting the burn requirements for plenum applications has a core formed of one or more twisted wire pairs having primary insulation formed of a suitable material, such as high density polyethylene. The core is surrounded by a single outer jacket formed from a material having excellent heat/flame resistance characteristics and acceptable electrical characteristics that are substantially stable at relatively high temperatures, s...

A device for shaving jacketed sticks comprises a housing block, a shaving knife supported in the housing block, an orifice in the housing block for introducing a jacketed stick and bringing it in contact with the shaving knife, first and second chambers in the housing block for receiving, respectively, jacket shavings and material removed from the stick; and a septum separating the first and second receiving chambers from one another.

A jacketed pipe flange (10) for connection to an end of an inner pipe (12) and to an end of a jacketed outer pipe (14) surrounding the inner pipe includes a central throughport (16) for mating with the inner pipe. The first annular sealing surface (18) surrounds a central throughport for sealing fluid within the inner pipe, a second annular sealing surface (20) surrounds the first sealing surface, and a third annular sealing surface (22) surrounds the second annular sealing surface for sealing f...

The jacketed active magnetic bearing is applied to a rotary machine having a rotor in contact with a process gas and placed in a leaktight enclosure. The magnetic stator is protected by a first jacket of magnetic anti-corrosion material that constitutes a portion of the leaktight enclosure and that is secured to the bearing stator, and the detector stator is protected by a second jacket of non-magnetic anti-corrosion material that constitutes a portion of the leaktight enclosure and that is secu...
