Abstract: A coupling for joining pipe segments together is disclosed. The coupling is derived from a standard fitting and has a housing with a socket and a first expanded region adjacent to the socket, a second expanded region adjacent to the first expanded region and a third expanded region adjacent to the second. A sealing member is positioned in the first expanded region, a retainer is positioned in the second expanded region and a support washer having transversely oriented radial and coaxial flanges is positioned adjacent to the retainer in the third expanded region. A lip turned inwardly on the second expanded region overlaps the radial flange and captures the support washer, retainer and sealing member within the coupling. The retainer has a plurality of radial teeth angularly oriented to engage a pipe and prevent its removal from the coupling.

Abstract: A coupling for joining pipe segments together is disclosed. The coupling is derived from a standard fitting and has a housing with a socket and a first expanded region adjacent to the socket and a second expanded region adjacent to the first expanded region. A sealing member is positioned in the first expanded region, a retainer is positioned in the second expanded region and a support washer having transversely oriented radial and coaxial flanges is positioned adjacent to the retainer. A clamping tab turned inwardly on the second expanded region overlaps the radial flange and clamps the support washer and retainer against a shoulder within the second expanded region thereby also capturing the sealing member within the coupling. The retainer has a plurality of radial teeth angularly oriented to engage a pipe and prevent its removal from the coupling. The teeth are twisted about their longitudinal axes.

Abstract: An open end of a standard pipe fitting is enlarged in diameter to coaxially receive an O-ring and a retainer having a cylindrical surface. A plurality of locking teeth project from the cylindrical surface and are engageable with both the inner surface of the fitting and an outer surface of a pipe end inserted coaxially into the fitting open end. Each of the locking teeth have oppositely disposed edges facing obliquely inwardly and outwardly to engage both the pipe end and the fitting and resisting motion of the pipe end relatively to the fitting. In an alternate embodiment, a first plurality of teeth each have an edge facing obliquely inwardly of the fitting to engage the pipe end and resist motion tending to withdraw the pipe end from the fitting. A second plurality of teeth each have an edge facing obliquely outwardly of the fitting and resist motion tending to withdraw the retainer from the fitting.

Abstract: An ammunition canister includes a pair of injection molded outer shells with each shell configured for assembly with another shell to form the ammunition canister. Each shell is molded with guide surfaces for controlling movement of ammunition rounds within the canister. An injection molded spring housing assembly, rotatably mounted to one of the shells, includes a spring for applying torque to said drive sprocket and a crank and ratchet are provided for tensioning the spring.

Abstract: Carrier clip apparatus for use in linear linkless ammunition systems, including a cradle attached to a chain along with a plurality of legs, protruding from one side of the cradles, for guiding an ammunition round as the chain is moved in the linear linkless system and for enabling ammunition round transfer as the cradle and chain pass around a chain sprocket. Also provided is a retainer clip, attached to an opposite side of said cradle with a bendable edge portion extending to one side of the cradle in a spaced apart relationship with the legs, for releasably holding said ammunition round in the cradle and against said leg means.

Abstract: A feature of this invention is the provision of a mount for a Gatling type gun having a muzzle clamp which is journaled for rotation in a reciprocable mass and which reciprocable mass is journaled for longitudinal reciprocation with respect to stationary support guides. Additionally, the housing is coupled to the support structure by a combination of a recoil adapter and a rigid guide, one end of the adapter and one end of the guide having a common transverse attachment to the support structure, the other end of the adapter having a pivot to the housing which is journaled for longitudinal reciprocation to the guide. This arrangement increases the recoiling mass without significantly increasing the total weight, precludes bending of the recoil adapters, and reduces frictional interferences.

Abstract: A feature of this invention is the provision of a gun bolt for a Gatling type gun having a carriage with a head journaled therein and a firing pin journaled in said head together with a cocking pin disposed in a slot passing through the firing pin, the head and the carriage with a detent disposed in a longitudinal bore of said head aft of said firing pin and having a portion thereof extending forwardly through a longitudinally extending bore in said firing pin and into a cavity in said cocking pin with a spring means disposed in said longitudinal bore of said head aft of said detent and biasing said detent into engagement with said cocking pin.

Abstract: A feature of this invention is the provision for a Gatling type gun of a gun bolt of the oscillating head type having a gun bolt carriage with substantially radially projecting slides and a head with substantially radially projecting locking lugs, wherein the length of the radial projection of the slides is significantly greater than the length of the radial projection of the locking lugs.

Abstract: A feature of this invention is the provision of a Gatling type gun whose gun barrels are arranged in a truncated cone and whose gun bolts are coaxial with their respective gun barrels.

Abstract: A feature of this invention is the provision of a Gatling type gun having a housing; a rotor journaled for rotation with respect to said housing; said rotor having a plurality of gun bolts disposed in an annular row with respective firing pin assemblies, and switchable firing pin assembly control means fixed with respect to said housing for sequentially engaging each of said firing pin assemblies and having a first disposition for positively precluding searing of each firing pin assembly and a second disposition for forcing timely searing of each firing pin; said firing pin assembly control means including a first cam surface having a longitudinally forward, lower portion, and a longitudinally rearward, higher portion which thereafter abruptly falls off into a lacuna; a second cam surface disposed in said lacuna and transversely pivotally mounted and supported for longitudinal movement to and between a first disposition whereat it provides a gradual decline between said higher portion to said lower portion of

Abstract: This invention provides for a clamp system for the cluster of barrels of a Gatling type gun which locks each barrel in the cluster against rotation about its own longitudinal axis and which minimizes relative transverse movement of each of the barrels.

Abstract: A pharmaceutical suspension of titanium dioxide for use in admixing with gelatin solutions for the manufacture of empty opaque gelatin capsules is provided which comprises: titanium dioxide, glycerin, sodium lauryl sulfate, simethicone, sodium citrate and water. A process is also provided which entails the requirement for adding the sodium citrate as the final ingredient in the suspension.
