Abstract: It is often necessary to unfold the integral carrying case of a device such as a portable electronic instrument comprising an upper and lower module. However if it is necessary upon unfolding the case to move apart the modules a limited distance while maintaining their relative alignment the common scissor-slider mechanism will not suffice inasmuch as the scissor mechanism does not latch on retraction and rotation. The disclosed invention provides a scissor-slider mechanism that extends without constraint in the usual fashion, but upon retraction and rotation about the slider axis required for folding the scissor-slider mechanism self-latches, keeping the upper and lower modules from separating.

The pipe receiving portion is adapted to receive a pipe therein and includes a clip fitting part. The clip fitting part has an engaging hole for engagement with an engaging claw formed on the clip. The engaging claw moves from a protruded position for preventing removal of the pipe to a withdrawn position for permitting removal of the pipe from the pipe receiving portion as the operator forces the clip to be enlarged. An enlargement restraining device is provided that is operable to restrain the enlargement of the clip within a predetermined range, so that the clip can reliably resiliently return to the protruded position when the clip is released after the pipe has been removed from the pipe receiving portion.

Abstract: An apparatus for protecting the gate of an animal enclosure with an electrified wire that also extends along fencing includes a reel that dispenses and collects the wire to minimize the possibility of shock during gate opening and closing procedures. A hollow reel housing is mounted to a first fence post to which the gate is hingedly attached. A truncate wire connected to a source of electrical power such as an electrified fence wire extends into the hollow reel housing through a first opening and is connected to a nonrotating electrical contact. An annular rotating electrical contact is in electrical communication with a proximal end of wire coiled about the reel and is mounted on the reel so that the wire remains in electrical communication with the source of power when the reel is rotating in a wire-dispensing direction or in a wire-collecting direction. The wire, when uncoiled, extends through a second opening formed in the hollow reel housing.

Abstract: A service riser 10 comprises a steel jacket 11 around a polyethylene pipe 12 which terminates in the riser at a transition zone 20. The transition zone 20 comprises a retainer sleeve 30 inserted in the end of the pipe 12 and sealed thereto by an O-ring 38. The retainer sleeve 30 extends out of the pipe 12 and is provided with grooves 46 separated by lands 48 on which an elastomeric sealing band 52 is received. The tube 11 is swaged down forming a swage groove 56 around the retainer sleeve 30 compressing the gasket 52 to a large extent over the lands 48 and a lesser extent over the grooves 46, the ideal compression for the gasket 52 being arranged somewhere between such degrees of compression. By this means the ideal degree of compression at some regions of the gasket 52, forming an annulus around the retainer sleeve 30, is guaranteed, despite tolerances in the dimensions of the tube 11 (especially) as well as the band 52 and sleeve 30.

Abstract: The mounting assembly is for adjustably mounting an accessory having a substantially planar portion onto a rail member having a longitudinal side channel with opposite longitudinal folds. The mounting assembly has an elongated latch member shaped for passage between the folds when the latch member is oriented substantially parallel to the channel, and for abutment against the folds when the latch member is turned at least partially transversely inside the channel. The mounting assembly has a tightening device for tightening the accessory to the latch member. A locking device is operatively associated with the planar portion of the accessory and the latch member to prevent relative rotation and translation thereof when the accessory is tighten to the latch member.
