  • Patent number: 10550990
    Abstract: A protective shield device is disposed at the joint between connected concrete hoses to protect the joint connecting one concrete hose to another from accidentally catching on an obstruction on the surface over which the concrete hose joint is moved during operation and disconnecting the two concrete hoses. The protective shield device is formed by two housing portions that are hinged on one side and connected by one or more retaining elements to surround and encapsulate the concrete hose joint. The closed protective shield device has a larger central portion to accommodate the joint structure, and narrower end portions to provide no protruding structure that will catch any underlying obstructions that could cause the enclosed joint latch to be exposed.

  • Patent number: 10533690
    Abstract: The invention provides improvements to electrofusion fitting methods that allow for continuity and repeatability of welds between an electrofusion fitting and a pipe lining (or stand-alone pipe). An electrofusion fitting for joining sections of lined pipe has heating elements configured to create at least one weld between the electrofusion fitting and a pipe lining. However, prior to the weld step taking place the electrofusion fitting is heated and expands accordingly to ensure contact with the pipe lining. Preheating the electrofusion fitting also provides a predetermined starting temperature for the fitting and the lining which results in improved fusion cycle reliability. Furthermore, the need for clamps or support frames to support the electrofusion fitting in situ is removed, with corresponding reductions in cycle times, complexity, and hence cost.

  • Patent number: 10473249
    Abstract: A method and apparatus for an improved safety cam lock fitting having double cam levers having outer and inner portions so that when the outer cam levers are opened and the inner cam lever remain closed, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. This is accomplished by providing a larger cam lobe on the outer cam lever and a smaller cam lobe on the inner cam lever so that when the smaller cam lobe is in a closed position and protrudes into a peripheral groove on the male portion the male and female ends have a small space therein between. Various configurations of the cam portions relative to each other are provided. Various lever locking assemblies may be used to prevent the cam levers from being inadvertently opened.

  • Patent number: 10458583
    Abstract: The quick release tool includes a U-shaped body which presents a base that has a first side and a second side. The body also has a pair of legs that are spaced laterally from one another and extend away from the first side of the base to respective distal ends. Each of the distal ends presents a pair of ledges that are spaced longitudinally from one another to receive fingers on the locker of the quick connector assembly. The base of the U-shaped body presents a living hinge which is spaced laterally between the legs for pivoting the distal ends of the legs away from one another in response to the application of a force onto the second side of the base, thereby allowing the locker to be moved from the locked position to the unlocked position.
