Abstract: An escutcheon component system which fits around a pipe at the point wherein the pipe projects through a wall includes an escutcheon plate and a generally cylindrical insert. At least the periphery of the back side of the escutcheon plate is capable of abutting against the wall. A hole through the escutcheon plate is sized so that a pipe can pass through it. An annular flange extends outwardly from the back side of the escutcheon plate co-cylindrically with the hole. The insert is formed of a flexible material such that it is capable of being compressed and inserted into the interior of the flange. An opening through the center of the insert allows the insert to be passed over the pipe, and when located around the pipe the insert will grip the pipe if the insert is then compressed within the interior of the flange. When the insert is located around the pipe and within the flange frictional forces hold the escutcheon component system to the pipe.

Abstract: A tubing retrievable differential pressure operated well safety valve which closes at a predetermined rate of flow which may be changed from the well surface. A housing is adapted to be threadedly connected to well tubing. A spring forces a flow tube and choke bean downwardly to normally hold the valve open, but when the producing rate increases to a preset value the bean and flow tube moves upwardly overcoming the spring allowing the valve to close. A releasable connection is provided between the choke bean and the flow tube for connecting the choke bean to and releasing the choke bean from the flow tube by longitudinal movement of the bean relative to the flow tube. The connection may include a collet interconnecting the beam and the flow tube in which the collet includes an enlargement for engaging a recess in the bean. The flow tube includes a backup shoulder for locking the enlargement in the recess and also includes an opening for allowing the collet to become released from the bean.

Abstract: A coupling is provided for the repair of flexible conduit, such as garden hose, comprising a body portion having at least one nipple for insertion into the free end of the flexible conduit. A slotted collapsible collet is radially compressed by a retaining nut thereby clamping the conduit between the nipple and the collet. The collet is generally frustoconical in shape and is reversible for retaining one size of conduit when disposed in a first direction and a larger size conduit when reversed. In order to accommodate a still larger conduit, the collet can be omitted. The body can include a second nipple which can be similarly attached to the free end of a conduit to effect repair of the conduit. Alternatively, the body can include a male or female fitting, a pair of which can be joined to effect repair of a conduit, or used separately in connection with other suitable fittings, as desired.

Abstract: A pipe coupling which includes a continuous ring-shaped gasket that can be fitted around the abutting ends of two pipes and a clamp that can be fitted around the gasket and around flanges of the pipes. The clamp includes a grease fitting, while the gasket has a pair of upstanding flanges or ridges near its axially opposite ends, to form a grease reservoir that can hold grease under pressure. The grease applies pressure that helps seal the gasket against the pipe ends. The grease leaks out especially when the pipe carries pressure pulses, to lubricate the coupling so as to facilitate the turning of one pipe relative to the other with minimal wearing of the gasket. The gasket has a pair of inwardly-directed flanges that can rest upon the pipe flanges at the ends of the pipes and that are of greater height than the outer gasket flanges. The gasket can be easily turned inside-out, so that the thick flanges form a grease reservoir to enable more grease to be held in heavy duty and repeated rotation applications.

A pivotal member is sealingly mounted in the second housing opening for pivotal movement relative to the housing. A rod slidably penetrates a throughbore provided through the pivotal member, and has one end arranged to move toward and away from the hole. This rod end carries an adapter which may be engaged with a fitting. Thereafter, the rod may be selectively manipulated to move the fitting relative to the hole.

The sealing ring may be made symmetrical, is discontinuous, has an inside bead for sealing against the conduit and may include wings for retention in the gland nut prior to assembly of the fitting on a conduit end.

Abstract: An airless spray gun reversible spray nozzle unit is provided adapted to replace the normal or standard fixed spray position unit without any modification of the external spray head. The external spray head normally positions and holds the fixed position spray nozzle unit in spray position in the airless spray gun. The present adaptation is made possible by means of a floating or sliding female ferrule axially movably positioned and slideable intermediately between a pair of spaced apart keyed flanges defining the unit size which act as stops therefor and assures a leak-proof machined fit of the reversible nozzle when the inventive spray nozzle unit is positioned to spray, or in reversed position so the orifice of the nozzle can be backwashed and freed of binding occlusions.The size, weight and form of the unit adds substantially no increase in weight or volume to the conventional fixed position airless spray head spray nozzle unit and is easily and quickly manually reversed when desired.

Abstract: A quick connect/disconnect coupling assembly particularly adapted for underwater use, having a pair of coupling members, one of which is mounted on a relatively rigid structure, and a sleeve mounted over the first coupling member for relative axial and rotational movement. The sleeve is guided by a single or double J slot between axially extended locking and axially retracted unlocking positions. In the locking position, a cammed surface on the inside of the sleeve engages a ball and socket arrangement on the coupling members to prevent the coupling members from becoming unlocked; in the axially retracted unlocking position, the cammed surface of the sleeve is moved away from the ball and socket arrangement to permit free radial movement of the ball out of the socket and relative axial movement of the coupling members into and out of coupling engagement with each other. The sleeve is lockable in the axially extended locking position to provide a positive lock.
