Method and apparatus for an improved camlock fitting having outer/inner cam lever which are restrained against unintended opening or rotation by a pivoting locking member which is pivotally mounted onto an axle disposed in a corresponding hole on the cam levers so that the pivoting locking member can be easily pivoted in the vertical plane relative to the cam arms. Each of the outer and inner arms has a pivoting locking member mounted on its underside in a protective housing. The camlock fitting may also have an air vent. Together this provides a safety lock assembly for the cam lock fitting so that when the cam lock fitting is pressurized unbeknownst to the operator and the operator attempts to open the cam lock fitting, the safety lock assembly will prevent operation or complete separation of the male and the female portions of the fitting to prevent inadvertent pressurized discharge of hazardous materials.

A compression-type fitting for quick connection of two hoses or hose sections and pipe and hose section in-line is adapted primarily for industrial, heavy duty hoses typically in one to three inches in diameter, although not so limited. A commercial application for which the connector has shown to be particularly useful is in the media blasting industry where hoses are subject to extreme conditions and break or leak after a relatively short period of use, requiring frequent shut down and repair or replacement of the hoses.

The present invention relates to an underground pipe coupling for an emergency repair during pipe breakage and comprises a ball and socket coupling joint having a ball joint (5) which is free to rotate inside a socket joint (3) fastened by means of a ball joint backing ring (4) along with an O ring (7) positioned in between them. A pair of grip cam mounting plates (1), with grip cams (6)/double grip cams (6a) are provided, one of which connects at one end of the broken pipe and ball joint (5), and the other one connects the other end of the broken pipe and the socket joint (3) in a watertight manner by means of a resilient sealing ring (2) placed in between each one of them. The grip cams rotate on eccentric axes in the counterclockwise direction and prevent the decoupling of the pipe joint.

A cam ring for a pipe connector includes a first axial side, a second axial side opposite the first axial side, a radially outward-facing side, a radially inward-facing side, and a cam element extending a circumferential length along the radially inward facing-side. The cam element includes a first cam section and a second can section, the cam sections respectively have first and second radially facing cam surfaces adjacent respective first and second axially facing cam surfaces. The second radially facing cam surface has a second radial depth lesser than a first radial depth of the first radially facing cam surface. The second axially facing cam surface has a second axial location closer to the first axial side than a first axial location of the first axially facing cam surface. A gripper for a pipe connector includes a body and teeth with an arc shape.

According to one aspect, a reactor for generating lifting gas may include a first port, a second port, a coupling releasably securable in fluid communication with an aerostat, and a tank including a base and a crown defining at least a portion of a chamber therebetween, the first port and the coupling each supported on the crown, the second port supported on the tank away from the crown, the chamber in fluid communication with each one of the first port, the second port, and the coupling, the chamber expandable between the crown and the base from an uninflated state to an inflated state and, with the tank in the inflated state, a maximum height of the chamber less than a maximum dimension of the base.

Various aspects of the invention described herein relate to a removable connector assembly, and methods of use and manufacture thereof. More particularly, certain embodiments relate to apparatus and methods to provide a connection to a spout disposed upon a container, such as upon a bag holding fluid. Embodiments of connector assemblies comprise an elongated outer housing, an inner housing, and a slider assembly for moving the outer surface of the sleeve member over the inner surface of the outer housing wall in a lengthwise motion to position the spout connector upon the spout and secure the spout connector in said position.

A connection nozzle assembly includes an inner fluid product tube, a tube sleeve secured about the fluid product tube, an outer nozzle sleeve, and a locking mechanism disposed between the fluid product tube and the nozzle sleeve. The nozzle sleeve includes a body portion and a rear portion, each being moveable between a plurality of locking positions. The body portion has at least one J-groove bracket disposed therein and the rear portion has a guide element extending into the bracket. The locking mechanism includes at least one clamping member moveable between a plurality of clamping positions and at least one drop pin moveable between a raised position and a lowered position. The nozzle sleeve is moved between the plurality of locking positions, thereby engaging the locking mechanism to secure the connection nozzle assembly to a receptacle coupling. The connection nozzle assembly can be uncoupled by reversing the nozzle sleeve.
