Abstract: An expandable section mill includes a body having an outer surface and an inner cavity, a piston disposed within the inner cavity, a jaw member pivotally connected to a lower end of the body, and a blade assembly affixed to a tapered surface of the jaw member. The tapered surface of the jaw member includes a wear surface below the blade assembly. The jaw member includes an internal channel system for fluid flow through the jaw member to one or more outlets on the jaw member. The piston is moveable within the inner cavity for pivoting the jaw member between a retracted position and an extended position. In the retracted position, the blade assembly is positioned radially inward relative to the outer surface of the body. In the extended position, the blade assembly extends radially outward relative to the outer surface of the body.

Abstract: An expandable section mill includes a body, a piston movably disposed within an inner cavity of the body, the piston including a wedge surface, a jaw member pivotally connected to a lower end of the body, and a blade assembly affixed to a tapered surface of the jaw member. The jaw member includes an internal channel system for fluid flow through the jaw member to one or more outlets on the jaw member. The jaw member includes a pivot surface. The wedge surface of the piston engages the pivot surface of the jaw member to pivot the jaw member between a retracted position and an extended position. In the retracted position, the blade assembly is positioned radially inward relative to an outer surface of the body. In the extended position, the blade assembly extends radially outward relative to the outer surface of the body.

Abstract: A quick-connecting coupler for connecting hoses, connectors together or to a faucet or other water accessories that allows ease of use by anyone, including the elderly, the infirm, and those suffering from disabilities. The quick-connecting coupler has a first male-end and a second female end. The second female end is provided with of spaced-apart through-slots or opening for receiving therethrough a pair of forks or leg-sections of a yoke. Each of the pair of forks or leg-sections is provided with at least one interior-facing linear thread or rib for engaging with the male threads of the mating male end of another hose, or the like. The second female end of the coupler of the invention has a pair diametrically opposed cutouts through which portions of the linear threads or ribs are exposed.

Abstract: A coupler for coupling an end of a hose to a mating end of a faucet or another hose. In the first embodiment, the female end of the coupler is mechanically locked in sealing engagement with a male end by simply translation thereof by means of wedges and an outer retaining sleeve. In a second embodiment, hydraulic pressure provides the final seal, with the female end being a spring split-ring locked and compressed by means of an outer locking sleeve, which outer locking sleeve is released by squeezing it in order to deform it. A third embodiment combines the first and second-embodiments.

Abstract: A hose-coupler made up of a just one component having a main housing section with a female end and a male end. The second female end of the coupler is formed with interior threads, for receiving therein a portion of the male end of the second hose. The main housing section has a compressible portion adjacent to the first male end thereof all the way to the end of the female end. In order to compress the clamping jaws, there is provided a slidable outer housing. The male end is sealed in the female end of the coupler by a biased piston-member that forces a sealing washer against the male end by means of the pressurized fluid volume in the interior of the coupler. Two embodiments are disclosed: A first one that allows the coupler to be disconnected from the male end of a hose only after the water pressure has been turned off; and a second embodiment that allows the coupler to be disconnected from the male end of a hose also while the water pressure is still present.
