Abstract: A strip of reinforcing material having a reverse bend section along one side edge is bendable to be wrapped around the rim of a container, such as a garbage or trash container. The reverse bend section forms a groove to receive the container rim and the remainder of the strip forms a protective and reinforcing skirt to prevent damage to adjacent portions of the container and to reduce noise incurred in handling the container.

Abstract: A safety release pipe cap for emergency venting of fluids under excessive temperatures by melting out a replaceable portion. In one embodiment the replaceable portion is arranged to yield under excessive pressure differentials on its opposed faces. The cap is employed on tanks. A threaded ferrule is provided with a flange overlying the end of a pipe with which it is threadingly engaged to clamp the periphery of a separable disk of thermally fusible material against the pipe end. When the disk is of a yieldable plastic it functions as a seal gasket on the pipe end and will yield under pressure differentials to provide a visual indication of such differentials by material and wall thickness characteristics as well as the geometry of the disk. Temperature fusing can be controlled by these characteristics and particularly the melting temperature of the plastic.

Abstract: An end cap for closing an open end of a pipe. The end cap is formed with a sleeve of plastics material closed at a first end by a wall and having tongues formed integrally with the sleeve on the opposite or second end. These tongues fit in openings in a plastics clamping ring at the second end of the sleeve and engage with a side of the ring to prevent removal of the clamping ring. The clamping ring holds a sealing ring of rubber material around the inside of the sleeve for sealing engagement with the pipe fitted into the sleeve through the second end of the latter.

Abstract: A cap for installation over the open end of a tubular member that has a pipe or pipes of smaller diameter projecting through the open end of the tubular member. The cap has a rubber discoid portion that covers the open end of the tubular member and a rubber apron extending from the discoid portion and adapted to encircle the tubular member adjacent to its open end. An aperture or apertures for the pipes of smaller diameter are provided in the discoid portion. The cap is split except at the back where a portion including the apron provides a hinge. The split intersects the aperture or apertures. A split, flexible metal band is embedded in the apron and has a latch for tightening and locking the apron about the tubular member. To install the cap, it is hinged open and placed over the end of the tubular member with the smaller diameter pipes passing through the apertures, and is then closed around the tubular member and locked.

Abstract: A drain plug for axial insertion into a conduit having an inner surface, including a cup-shaped resilient sealing member having a closed end and an open end and having a sidewall having an outer surface conforming to the inner surface of the conduit and with the cup-shaped member normally axially slideable into the conduit, first means intercoupling the closed and open ends of the cup-shaped member for axially compressing the cup-shaped member to flex the sidewall radially outward to engage and seal against the inner surface of the conduit, and second means coupled to the first means for moving between first and second positions for actuating the first means to compress the cup-shaped member with the second means moved from the first to the second position.

Abstract: The disclosure generally relates to a method of joining a pipe to another pipe, or to an adjacent pipe in a series of pipes in a pipeline, the joints between which incorporate sealing means, and an apparatus suitable for use in performing the method, which basically involves forming an enclosed space at least bridging the joint to be formed and evacuating the space by a vacuum pump or ejector to produce a pressure within the space lower than atmospheric pressure to allow the greater atmospheric pressure outside the pipes to axially force the pipes together against the resistance of the means forming the sealed joint between the pipes. This function may be achieved by closing the ends of the pipes to be joined remote from the position of the joint and evacuating the space within the pipes and between the end closures.

Abstract: A flying object, such as a missile is protected against shock loads, especially loads effective in the longitudinal direction, by a shock absorber which is secured to the muzzle end of a launching tube by an adapter ring. The absorber itself is a pipe section of relatively soft elastic material having embedded therein a helical insert of relatively hard elastic material.

Abstract: In order to avoid the necessity of having a range of sizes of tools for the mounting and removal of a plurality of resiliently deformable plugs of different transverse dimensions on the ends of associated tubes, there is provided a plurality of such plugs which can all be mounted on, or removed from, the ends of the associated tubes using the same tool. In the plugs, each of which comprises a circular disc portion, an annular skirt portion projecting from the periphery of the disc portion to one side thereof, and a pin member which projects in the direction of the longitudinal axis of the plug from the center of the disc portion to said one side thereof, with the skirt portion presenting an outwardly directed annular closure member having an outer diameter which is reducible by resilient deflection of the disc portion to either side thereof, the transverse cross-sectional dimensions of the pin members of the plugs are the same.

Abstract: A dust cover for selective use in sockets of different cross sectional configurations. The couplings are provided in hydraulic lines between a tractor and an implement where coupling and decoupling of the interconnected line is needed. The cover is used in the socket end of the coupling for cleanliness of fluid handling in the hydraulic system and to assure that the impurities are not allowed to contaminate the system by entrance into an open socket when the coupling is decoupled.

Abstract: A one piece protector for the machined surface of a flange for pipes and valves which may be installed and removed by finger pressure on integral thimbles which frictionally engage the bores of the bolt holes of the flange.

Abstract: An adapter for connecting a nozzle or similar attachment to the threaded end of a garden hose or the like has a body with an internally threaded end connectable to the hose threads and a spring loaded retractable coaxial sleeve which extends over and protectively covers the external threads at the other end of the body to which the nozzle is connectable. When the nozzle is to be connected to the adapter, the sleeve is withdrawn over the body, compressing the spring and exposing the external threads to the nozzle. When the nozzle is disconnected, the spring expands and returns the sleeve to its protective position surrounding the threads.

Abstract: A disposable end closure for pipe and tube ends such as, for example, vehicle fuel filler openings. The disposable end closure includes a cylindrical portion for inserting axially into the open end of the pipe or tube. The cylindrical portion has an outside diameter slightly smaller than the inside diameter of the pipe or tube. At the axially outer end of the cylindrical portion is a first flange which extends radially outwardly from the cylindrical portion. The axially inner end of the cylindrical portion is closed. A second flange extends radially outwardly from the sidewall of the cylindrical portion and engages the inner wall of the pipe or tube axially inwardly from the end thereof.

Means are also provided to prevent building of scale within the ferrule.

Abstract: A device to form an effective environmental tight seal on a free end of cables, conduits and the like is disclosed. The subject device is formed by a unitary member of resilient material, such as rubber, which has a cylindrical configuration with one permanently closed end. The closed end has a substantially greater thickness than the sidewalls of the device. The other end is preferably temporarily closed. The device is applied by forcing the permanently closed end against the free end of the cable so that the closed end passes through the cylindrical portion until the device is reversed upon itself and is in sealing gripping engagement on the cable or the like. When one end of the device is temporarily closed by a sealing member, the device will be slightly inflated as it is pushed against the cable end thereby easing application of the device. The temporary seal will be removed by penetration or when internal pressure increases beyond a limit.
