Abstract: A RV winterizing method that introduces antifreeze to a RV system using a reverse flow procedure by using fittings or a coupling, where the coupling includes a band composed from a strip with a set of ends which over lap when the strip wraps around itself, a knob situated above the set of ends at a top portion of the band, wherein the knob adjust the band. A semi-tubular fitting is braced within the band where the semi-tubular fitting includes a set of lips extending up an inner wall of the band. A hole arranged at a central bottom portion of the semi-tubular fitting. Finally, a fitting continuing from the hole wherein the band attaches to a faucet to create a watertight seal, and enables a non-toxic antifreeze to flow through the fitting, into the faucet and into a plumbing system.

Abstract: A pipe stabilizing system includes a pipe having an inlet and an outlet. An angled inner plate has a first portion and a second portion. The first portion has a first aperture defining a saddle for receiving pipe. An angled outer plate has a first section and a second section. The first section has a second aperture therein defining a saddle for receiving pipe. The first aperture in the inner plate is aligned with the second aperture in the outer plate when the second section is abutted against the second portion. The pipe is positionable in each of the first and second apertures and secured between the first portion and the first section. Fasteners are extended through the second portion and the second section and then into a hood housing. A fire retardant supply line is fluidly coupled to the inlet and a nozzle is fluidly coupled to the outlet.

Abstract: Apparatus for a security bracket for locking a sewer discharge hose for a recreational vehicle to the inlet pipe of the septic tank such as might be used at an RV sewer dumping station at a roadside park. The apparatus eliminates spillage and secures the sewer discharge hose to the inlet pipe of the septic pipe so as to eliminate spillage and the loss of sewer gases from escaping to the air. The apparatus discloses a bracket connected at its upper surface to the elbow of the sewer hose elbow and at its lower end to the inlet to the septic tank. A clamp secures the bracket to the septic tank inlet.

Abstract: A duct connection assemble, whereby upon connecting a saddle flange (2a) of the joint duct (8) to the main ribbed duct (3) through the communication hole (1b), the rubber sealant (1) is interposed between the saddle flange (2a) and a circumferential area of the communication hole (1b) so that protuberances (2b) uniformly press the rubber sealant (1) through the recesses (1d) to tightly engage the saddle flange (2a) against an outer surface of the main ribbed duct (3) through rib-fitting grooves (1a) and the water sealing small projective rings (1c). The joint duct (2) is brought into an elastical engagement with the main ribbed duct (3) to achieve a good water sealing action for an extended period of time.

Abstract: A clamp assembly prevents separation of a thermal sleeve penetrating a nuclear reactor pressure vessel wall and a jet pump riser elbow welded one to the other and lying within an annular space between the pressure vessel wall and core shroud. The clamp assembly includes a pair of heads having semi-cylindrical recesses. Pins project inwardly from each of the heads in the semi-cylindrical recesses and have axes which lie parallel to one another. By using actuators mounting multiple electrodes, holes may be formed in situ in the adjoining ends of the thermal sleeve and elbow. Once the holes are formed, the heads can be applied in situ with the pins being received through the holes and the heads clamped to one another. Thug, the pins in each of the sleeve and elbow prevent separating movement of the sleeve and elbow in the event of failure of the welded joint therebetween.

Abstract: A water purifying system includes filters for purifying tap water, a storage tank for storing the purified water, and a water discharge apparatus. The filters include a membrane filter which produces purified water and waste water. The water discharge apparatus includes a housing mounted on a sink, the bottom of the housing being open to accommodate a tap water supply conduit, a purified water dispensing conduit from the storage tank, and a waste water discharge conduit from the membrane filter. Mounted on the housing are first and second faucets communicating, respectively, with the purified water conduit and the waste water conduit for dispensing purified water and discharging waste water into the sink.

Abstract: Reject waste water adapter coupling fitting, system and installation method for use with a household undercounter reverse osmosis (R/O) water filtration installation associated with an in-counter sink having a garbage disposer with its outlet connected by standard slip fit plumbing fittings to a sink drain trap plumbed to the household sewer system. The R/O reject waste water undercounter drain line is coupled into the sink drain trap in parallel drainage relation with the disposer outlet plumbing fittings by a baffle Tee plumbing fitting having first and second inlets perpendicular to one another with their input drainage liquid flow separated by an internal baffle. The garbage disposer outlet is coupled by a standard slip fit single inlet/outlet conduit plumbing fitting to the baffle Tee first inlet. The baffle tee has a single outlet slip coupled to the inlet of the trap.

Abstract: A household under-counter reverse osmosis (R/O) water filtration installation wherein the R/O reject waste water under-counter drain line is coupled into a sink drain trap in parallel drainage relation with a garbage disposer sink by a baffle Tee plumbing fitting having first and second normally open inlets perpendicular to one another.

An R/O drain adapter elbow of the invention has its inlet connected to the waste water drain line tube and its outlet coupled to the Tee second inlet. The adapter provides an end closure structure which, with the elbow, sealably closes the second inlet of the Tee.

Abstract: An exhaust adapter for exhaust gas measurements which can be attached to the tail pipe of an exhaust unit and to which can be connected a hose leading to the analyzing measuring system. Two pipes, one telescoped into the other, are provided for attachment to a tail pipe. An elastic sealing ring is arranged between the end edge of the inner pipe and a drawn-in collar of the outer pipe. The outer pipe may be restrained with respect to the inner pipe for a gastight seal on the tail pipe by the measure of a compression of the sealing ring.

Abstract: On the wall of a booster shell which defines a vacuum chamber, a nonreturn-valve casing is formed in two halves. One casing half is formed integral with the wall of the booster shell and the other casing half is rotatably fitted to the former. With the first casing half formed in effect as a part of the wall of the booster shell, there is no leakage of vacuum from the booster shell to the exterior thereof. The second casing half has an L-shaped connector pipe formed integral therewith for connection with a vacuum line and the bent tip portion of the L-shaped connector pipe can be set in any radial direction simply by adjusting the angular position of the second casing half relative to the first.
