The apparatus includes a channel-shaped connector structure having an open side. The connector structure is receivable in an installed position engaging the open ends of the conduits, with the open side of the connector structure aligned with the open sides of the conduits. A fastener structure is mounted on the connector structure for movement with the connector structure relative to the conduits upon movement of the connector structure toward and into its installed position, and to restrain removal of the connector structure from its installed position.

Abstract: A doorbell system includes first and second pushbutton and an RF transmitter activatable by the first and second pushbutton. An RF receiver is configured to receive RF signals from the RF transmitter. The doorbell system further includes a microphone. A first storage device of the doorbell system stores a first sound. A second storage device is configured to record a second sound through the microphone. A playback device is operatively associated with the RF receiver and the storage devices to enable a user to select one of the sounds by pressing the first pushbutton and to play the selected one of the sounds by pressing the second pushbutton.

Abstract: Aligned circumferential grooves between a bell and spigot form a passage for receiving a locking strap that is insertable into the passage through an entrance opening in the wall of the bell. The locking strap has at least one projection adjacent the tail end portion thereof for engaging a surface of the passage to resist withdrawal of the locking strap from the passage. The entrance opening and the tail end portion of the locking strap have cooperating abutment and shoulder surfaces to releasably lock the strap within the passage.

Abstract: A coupling member has an internally threaded end portion and an opposite socket end portion with a pair of axially-spaced internal circumferential grooves. The internally threaded end portion receives an externally threaded end portion on a pipe, while the opposite socket end portion receives an end portion of another pipe that has an external circumferential groove aligned with one of the pair of internal grooves. A spline is inserted into the aligned grooves through a transverse hole in the wall of the opposite end portion of the coupling member to hold the coupling member and the other pipe against relative axial movement. The spline is a wire rope to provide high shear strength.

Abstract: A gangable electrical unit for positioning an electrical component beside an electrical outlet box includes a bracket with a wall structure and means for mounting the wall structure of the bracket on a wall of an electrical outlet box. In one embodiment, the means for mounting the wall structure of the bracket on a wall of an electrical outlet box is a pair of clips associated with the wall structure of the bracket for resiliently grasping a wall of an electrical outlet box when positioned adjacent thereto. In another embodiment, the means for mounting the wall structure of the bracket on a wall of an electrical outlet box is an adhering element positioned on an outward facing wall of the bracket. The clips and adhering element may be used simultaneously to adjoin the gangable unit to an electrical outlet box. A further embodiment includes a break-away stop extending outwardly from the wall structure of the bracket.

Abstract: A doorbell system having a sound memory for storing and playing a CD quality doorbell sound is disclosed. Said doorbell system includes a receiver unit for receiving an indication of a doorbell button being pressed, a code detector for commanding the sound memory to output stored sound signals and sound producing means for outputting a CD quality sound. Also disclosed is a method for storing a CD quality sound into a doorbell system.

Abstract: A floor box cover assembly includes a ring receivable within an open end portion of the floor box, and further includes a cover structure having an access opening for providing access to the receptacle. A cylindrical wall on the cover structure fits within the ring when the cover structure is installed over the ring. The ring and the cover structure together define a plurality of radially projecting pins and a corresponding plurality of J-hook slots that receive the pins upon installation of the cover structure over the ring. The slots are free of detent constrictions for interlocking with the pins. Additionally, the ring is a split ring and fits within the floor box in an installed position in which opposite ends of the split ring define a circumferentially extending gap. The cover structure has an alignment boss that blocks insertion of the cylindrical wall into the split ring in positions other than a position in which the alignment boss is received within the gap.

Abstract: An electrical utility box is configured to contain an electrical device. The box includes a bottom wall, two opposing side walls, two opposing end walls, a mounting boss, and a shield structure. The mounting boss has a bore configured to receive a fastener that fastens the electrical device to the box. The shielding structure is configured to block an uninsulated wire from contacting a portion of the fastener that protrudes from an open lower end of the bore.

Abstract: A coupling assembly for conduit or pipe comprising a first coupling member, a second coupling member and a locking member. The first coupling member is optionally a tubular component and the second coupling member or coupler is optionally a belled component. The present invention is also optionally provided with an annular sealing member.

Abstract: An apparatus for use with an electrical receptacle and a floor box. A first part of the apparatus defines a floor plate which is configured to fit over the floor box in an installed position. The floor plate has an inner edge surface defining an access opening for providing access to the receptacle. A second part of the apparatus defines an access door for closing the access opening. A detent structure is operative between the door and the floor plate to retain the door releaseably in the closed position. The detent structure includes an elongated spring which is mounted on one of the parts, and also includes a cam surface on the other part. A first end portion of the spring is anchored to the part on which it is mounted. A second end portion of the spring defines a cam follower.

Abstract: An apparatus is disclosed for making a conduit or pipe. An extruder is provided for producing a strip of continuous thermoplastic. A winding drum receives the strip and helically winds the strip around the drum's perimeter to form a conduit having an inner diameter corresponding to the outer diameter of the drum. The drum includes a core tube surrounded by a plurality of rollers which define the outer diameter of the drum. The rollers rotate to advance the strip around the drum. A plurality of support columns are used to support the roller at each end. A hub assembly is used to movably support the support columns in slidable engagement. The support columns are radially displaced by the hub assembly between two positions, in order to vary the outer diameter of the drum between two diameters.
