A pipe stem replacement kit having a plurality of tenons of different diameters, each tenon having one cylindrical side and one threaded side, a pipe stem having at one end a mouthpiece and at the other end a threaded aperture to receive the threaded end of a selected one of said tenons, sandpaper to sand down the tenon to fit the pipe shank aperture and wax to apply to the tenon to ease the insertion of the tenon into the pipe shank aperture.

A stem tip seal for a shut-off valve including a valve member adapted for selective movement axially toward and away from an associated valve seat. A generally cylindrical sleeve is carried by the valve member and has an end defining an outer annular seal surface adapted for cooperative sealing engagement with the seat. Mounted centrally within the sleeve for limited axial movement is a rigid cylindrical body that defines a first inner annular seal surface adapted for engagement with the seat at...

A molded thermoplastic valve stem oil deflector for an internal combustion engine comprises a two piece cup-shaped member having a skirt and a neck defined by two axially spaced radial flanges. The flanges have apertures therethrough defining a radially inwardly opening annulus for the acceptance of a conventional O-ring that seals on the valve stem and supports the oil deflector relative thereto.

A water valve adjustable stem assembly includes a valve housing with an inlet and outlet therein and a valve positioned within the housing. The valve has an inlet and outlet communicating with the housing inlet and outlet and there is a movable valve member to open and close the valve. A valve housing extension is adjustably connected to the valve housing and connects to an escutcheon. A stem extension is attached to the movable valve member and extends within the housing and housing extension a...

Monoclonal antibodies that recognize a stage-specific antigen on immature human marrow cells are provided. These antibodies are useful in methods of isolating cell suspensions from human blood and marrow that can be employed in bone marrow transplantation. Cell suspensions containing human pluripotent lympho-hematopoietic stem cells are also provided, as well as theraputic methods employing the cell suspensions.

The invention relates to a fishing lure having an elongated body with an internal throughpassage having a forward opening and a narrowed rearward opening. The lure body has a stem which is itself rigidly attached to the body at a position ahead of and below the center of mass of the body. A flexible portion of the stem extends upwardly and forwardly beyond the center of mass, and is adapted for attachment to a fishing line adjacent its free end. Tensioning of the fishing line causes the flexible...

An apparatus (23) is constructed having a pair of side gripping members (32, 34) which are pivotally coupled by hinges to an intermediate gripping member (36). These gripping members (32, 34, 36) have a l/d (length-to-diameter) ratio of approximately 5:1 to distribute compressive forces over a relatively large area. Inner gripping regions (46, 48, 50) of the members (32, 34, 36) are configured having frictional surfaces (46, 48, 50) which frictionally grip a tubular structure, such as a bi-stem ...

Balloon stem connector for securing a balloon by its neck to the end of a stem-like object includes a wire formed slot at the end of the stem for receiving the balloon neck. A capture element having a tubular body portion is fitted in sleeve-like fashion to slide along the stem from a position where the slot is fully exposed to a captive position where it envelops a substantial portion of the loop. The capture element also has balloon positioning body portions outwardly flaring from the tubular ...

A method and apparatus for capping a headed stem fasteners. The precursor web having a backing with a rear surface, a front surface, and a multiplicity of polymeric stems projecting distally from the front surface of the backing is fed into a variable nip between a heated member opposite a support surface. The support surface has a shape generally conforming to the contour of the heated member. The variable nip compressively engages the polymeric stems between the heated member and the support s...

A writing stem for writing instruments which can give an appropriate cushion effect to the griping thumb and fingers includes a grip section formed of an elastic material. A plurality of protruding pieces that can be bent by the gripping force are formed in parallel to one another on the surface of the grip section, including a portion about 30 mm to about 40 mm behind the tip of the writing instrument, and this plurality of protruding pieces are formed over a length equivalent to about 2/3 of t...
