An expansion repair coupling for interconnecting two facing ends of a cut pipe comprises a tubular body, a spigot slidably and rotatably received therein and a locking mechanism to selectively lock or unlock the rotation of the tubular body relative to the spigot. An end of the spigot extends outward from the tubular body to receive a coupling that connects to one end of the cut pipe. A radially enlarged section on the spigot has a sealing mechanism that sealably engages an interior surface of the tubular body. The locking mechanism, engaged by collapsing the spigot into the tubular body or disengaged by extending the spigot therefrom, facilitates a push and twist connection at both ends of the pipe to wipe the adhesive disposed therebetween and obtain a better seal. Preferably, the locking mechanism comprises a socket having spigot engaging members that cooperatively engage socket engaging members on the spigot.

A flow control device in which a flapper is continuously biased to the closed position by a leaf spring that may have a plurality of fingers. The same valve includes a shutoff mechanism allowing the user to adjust forward flow through the valve or shut it off entirely. The leaf spring is made to include polyoxymethylene.

An active sampler for detecting contaminants in liquids comprises an inlet, an outlet and a sampling unit positioned such that the liquid flows along a path from the inlet, through the sampling unit, to the outlet. The sampling unit has a plurality of sampling chambers that are substantially fluidly sealed relative to one another, wherein one of the sampling chambers is selectively positioned in the flow path. The active sampler also comprises an actuator, which relatively moves the sampling unit and the inlet and outlet such that one sampling chamber is positioned out of the flow path while another of the sampling chambers is positioned in the flow path.

An active sampler for detecting contaminants in liquids comprises an inlet tube, and outlet tube and a sampling unit positioned between said paths such that the liquid flows along a path from the inlet, through the sampling unit, to the outlet. The sampling unit has a plurality of sampling chambers that are substantially fluidly sealed relative to one another, wherein one of the sampling chambers is selectively positioned in the flow path. The active sampler also comprises an actuator, which relatively moves the sampling unit and the inlet and outlet tubes such that said one sampling chamber is positioned out of the flow path while another of the sampling chambers is positioned in the flow path.

A oil filter wrench and packaging arrangement therefore are disclosed. The oil filter wrench has a cup-shaped body with a socket formed therein for receiving the top of a conventional oil filter. The interior side wall has a step therein circumscribing the socket. The oil filter wrench can be packaged between a cardboard backing and plastic cover sheet such that the cover sheet over laps the rim of the cup-shaped body. The step spaces the plastic sheet from the socket, keeping the socket area open. With this packaging arrangement the consumer can try his oil filter with the wrench without destroying the package to determine whether the wrench suits his needs before purchasing it.

A container cap assembly for capping large bottles, jars and the like that provides a latch device in combination with a container cap assembly which includes a cap body and hinged cover on which is formed a latching tongue adapted to latch to the cap body. The latching tongue is formed having a midsection member that is preferably provided with an arcuate cross-sectional configuration having inwardly bent free edges which define a spring-action biasing means, whereby the free edges are placed in tension when the latching tongue is flexed outwardly away from a protruding lip member formed on the cap body.

An articulated soft doll construction in which a soft skin covers a soft doll head and a soft skin covers a soft torso in which the head is universally moveable relative to the torso. The torso has a first skin cover covering a fiber filler material. The torso and first skin cover are formed with an opening in which a neck connecting member is received. A second soft skin cover is used to cover a soft head that is filled with fiber material. A neck plug is received through an opening in the head and second soft skin cover. Disposed inside a neck plug is a ball and socket assembly in which the ball is connected to a spindle member that extends into the torso and is received by the neck connecting member for engagement therewith. A collar member is received inside the neck plug for retaining the second soft skin cover around the head. A remaining member is received by the neck connecting member to retain the first soft skin cover. The ball and socket assembly enables universal movement of the head relative to the torso of the doll while the first and second soft skin covers are retained.
