Abstract: A structure is provided for securing cable, which has internal working fibers and an external outer coat, to a terminal connector. Included in the structure is a crimp body which has an interior axial hole extending therethrough and an exterior surface with at least one groove and at least one ridge. The outer coat of the cable is placed around the exterior surface of the crimp body and a crimp ring is placed around the outer coat and the crimp body. The crimp ring is deformable and has an interior large enough to accommodate the crimp body and the outer coat. The crimp ring is deformable so that it can secure the outer coat between the crimp ring and the crimp body, with the groove and ridge arrangement of the crimp body further holding the outer coat in place.

Abstract: The present invention provides an adapter for sealingly receiving ferrules of standard optical fiber connectors such that the end faces of the ferrules are protected from moisture when inserted into the adapter. The adapter has a sealing sleeve that defines a sealing surface at each end to circumferentially seal about a ferrule. An alignment sleeve that is sized for operatively aligning the end faces of the ferrules is disposed coaxially inside the sealing sleeve. A retainer retains the sealing sleeve and allows for mounting of connectors thereto.

Abstract: A coupler is provided for coupling standard optical fiber connectors of the type with a ferrule extending from a connector housing. The coupler has a monolithic ferrule sleeve that defines a passageway configured for receiving and operatively aligning the ferrules from the two connectors to be coupled. A first latch portion is spaced from and generally parallel with the ferrule sleeve. A midpoint of the first latch portion is connected to a midpoint of the ferrule sleeve. A second latch portion is similarly connected to the ferrule sleeve opposite the first latch portion. The first and second latch portions are configured for engaging the connector housings of the connectors to be coupled.

Abstract: A pair of rigid metallic clips is inserted over containment numbers in a fiberoptic connector coupling. Rigid leg members mounted on the clips extend along latching members of the containment members, thereby limiting displacement of the latching members owing to spring pressure in connector sleeves joined by the connector coupling.

Abstract: A faucet-attached filter apparatus for filtering drinking water includes a unitary filter cartridge subassembly which provides a housing for the filter media, inlet and outlet porous media retainers, the filtered water outlet passage, and a quarter-turn connector with seal for simple cartridge insertion and removal from the filter housing.

Abstract: A shower dechlorinator is fabricated in the form of a short cylindrical filter housing. A first end cap is provided on one end of the housing, and this end cap is threaded onto the outlet pipe for a shower. A second end cap seals the other end of the housing and is adapted to be attached to a shower head. The filter housing is filled with granulated or randomly oriented fibrous material which chemically interacts with chlorine in the water passing through the unit. Typical filter material is in the form of a copper/zinc metal alloy.

Abstract: A stop valve has a valve body, a stem, and a handle. The valve body has a cylindrical cavity, which has a side wall and a first end wall, an inlet opening and an outlet opening, both of which communicate with the cylindrical cavity. The outlet opening has a side wall that intersects with the cylindrical cavity side wall; the intersection of which is chamfered. The valve stem has a cylindrical cavity portion which is located in the valve body cylindrical cavity and a handle portion which protrudes from the cylindrical cavity portion through an opening in the first end wall. The stem has an outlet seal ring and a stem seal O-ring. The stem seal O-ring is retained on the stem by a flange portion having a diameter slightly greater than the inside diameter of the O-ring. The stem has retaining ears to retain the stem in position in the valve body independently of the handle.

Abstract: A portable water treatment apparatus utilizing a cylindrical filter module having a spirally wound semipermeable membrane assembly includes interior upper and lower O-ring seals and an outer brine seal, all of which may be assembled without any potentially damaging movement between the seals and the respective interfacing surfaces in contact with the seals. Each of the O-ring seals is disposed between an annular shoulder on one interfacing part and a frustoconical surface on the other part such that a sealing compression is the only movement imposed on the O-ring. The brine seal, comprising a strip of adhesive-coated tape, is attached after the filter module has been placed in the housing such that it is in its final sealing position and is undisturbed by any subsequent assembly step.

Abstract: A slaker includes a substantially straight, circular sidewall, a substantially flat bottom, and a top. A solid and a liquid feed inlet are disposed at the top of the vessel and an outlet is disposed at the bottom of the vessel. Apparatus is provided for mixing the solid and the liquid within the vessel at high speed and separate apparatus is provided for sweeping the bottom and sidewall of the vessel at low speed. The mixing apparatus and the sweeping apparatus apply substantially only horizontal forces to the solid and the liquid being mixed within the vessel. The slaker further includes apparatus for recirculating at least a portion of the solid and the liquid being mixed within the vessel which flows through the outlet and apparatus for discharging the resultant mixed solid and liquid from the slaker.
