Abstract: The colostomy balloon plug has three parallel conduits with a combined charcoal and hydrophobic filter at one end of the largest central first conduit. The largest central first conduit is open at one end and has the combined charcoal and hydrophobic filter at its other end, for elimination of bowel gas. A shorter parallel second conduit terminates on one end in a first balloon and on a second end in a first one-way valve. A shortest parallel third conduit terminates on one end in a second balloon and on a second end in a second one-way valve. A syringe and extension conduit is selectively attached to the two one-way valves. Air, saline solution or sterilized water can be introduced from the syringe through the one-way valves of the extension conduit to inflate the two balloons about the largest central first conduit. The one-way valves prevent deflation of the balloons unless the shorter or shortest parallel conduits are cut to allow the fluid from the two balloons to exit and deflate the balloons.

Abstract: A cylinder valve for use with a cylinder containing fluid under pressure. The cylinder valve has an aluminum valve body. The valve body has a flow passage extending through the valve body for permitting fluid to flow through the body to exit the cylinder and a vent passage for permitting fluid to vent from the cylinder. Nickel plating is applied to the vent passage. A dispensing valve is positioned along the flow passage. Thermal relief material in the vent passage blocks flow through the vent passage until a predetermined venting temperature is reached when the material changes to a flowable state to unblock the vent passage and allow venting of the cylinder through the vent passage.

Abstract: A pressure washer for dispensing either water or a water-chemical mixture includes an injector for injecting chemical into water flowing through a hose at a relatively high flow rate. A sprayer connected to the hose has a passage having one upstream, one middle, and first and second downstream portions. The first downstream portion is connected to a high pressure conduit and the second downstream portion is connected to a high flow conduit less resistance to fluid flow than the high pressure conduit. A valve between the upstream portion and the middle portion selectively allows fluid flow to the middle portion of the passage. Another valve between the middle portion and downstream portion selectively allows flow to the second downstream portion and high flow conduit. Otherwise the valve directs flow through only the first downstream portion and high pressure conduit, which limits flow rate so as not to activate the injector.

Abstract: A buoyant float including a body having an interior defined in part by a side wall and a bottom extending inward from the side wall. The side wall has an upper edge defining an open top of the body. The float includes a cover sized and shaped for covering the top of the body. The cover attaches to the body to maintain the cover in position relative to the body to cover the open top. The cover has a tubular skirt extending downward and around the upper edge of the body side wall when the cover is in position covering the top of the body. An air pocket is created at an interface between the cover and the body when the float is positioned in liquid to isolate the interface from the liquid and prevent liquid from entering the hollow interior of the body through the interface.

Abstract: A default-to-park mechanism for a transmission includes an output member, a rotatable plate, a latching mechanism, and a biasing member. The output member is rotatable to park, reverse, neutral, and drive positions. The rotatable plate is coaxial with the output member. The plate and the output member interfere with one another such that the plate is moved in a first direction of rotation by the output member and the output member is moved in a second direction of rotation by the plate. The plate is releasably held by the latching mechanism to prevent rotation in the second direction of rotation when the output member is in the reverse, neutral, and drive positions. The biasing member biases the plate to rotate in the second direction of rotation to return the output member to the park position when the plate is released by the latching mechanism.
