Abstract: These fixtures aid in installing, sealing and securing pipe. Specifically, the invention aids in mating bell & spigot joints and securely capping open pipe ends of standard polyvinyl chloride (PVC), polyethylene (PE), and acrylonitrile-butadiene-styrene (ABS) pipe products as well as non-plastic piping by enabling equalized full circumference pressure on pipe ends to nudge, seal and/or secure pipe ends during installation or decommissioning.

Abstract: A quick release lock for a cover is provided. The cover may be a manhole cover for closing onto a manhole ring having a radially extended flange. The quick release lock mainly includes several angularly equal-spaced cross-shaped slots provided on the cover to communicate with through holes below them, and catch elements, push elements, and cotters in the same number as that of the cross-shaped slots. The catch element each is pivotally connected to and between two fixing plates provided at two opposite sides of each through hole. The cotter each is positioned in one cross-shaped slot and extended down into she through hole. The push element each is screwed on a bar portion of the cotter below the cover. When the cotter is depressed, the push element radially pushes the catch element outward to engage with a lower edge of the flange on the ring member and thereby firmly locks the cover to the ring member.

Abstract: An electromechanical locking mechanism for door leaves whose holding force can be adjusted continuously and which at the same time offers the possibility, when the locking mechanism is energized, of also releasing the closed door from and returning it to the locked position.

Abstract: A door hold open device for use with fire doors connected to a door closer unit. The hold open device has a latching means that automatically unlatches if the power supply drops below a predetermined threshold or a person attempts to disconnect the power supply. The device includes an electrical actuating means for unlatching the held open door. The actuating means allows a door to be latched open without constant current being supplied to the actuating means, so battery power is possible. The invention may be used with any door closer unit, does not require special wiring, and may include a self-contained power supply and an integral smoke detector.

Abstract: A safety tank cover clamp 10 has first and second elongated claw members 24 and 25 pivotally attached to yoke member 11. Threaded cylindrical traveler member 17 is treadedly engaged with treaded throughhole 16 in yoke member 11. Upper end 18 of traveler member 17 has handle 20 pivotally attached thereto. Lower end 19 of traveler member 17 supports a pivotally mounted engagement foot 22 for engaging tank opening cover 3. Right and left springs 31 and 32 are each generally centrally attached to one of the elongated claw members. The second ends of right and left springs 31 and 32 are attached to pivotally mounted spring centering bracket 34 which itself is centrally and pivotally attached to yoke member 11.

Abstract: A sealable, reusable shipping container having a highly reliable interior latching mechanism which is actuated on the exterior of the container without using special tools is provided. The unique latching mechanism can be adapted to securely closing and sealing any type of container. The latching mechanism converts the rotary force applied to an actuating device, such as a knob, into both vertical motion, for enabling a latch member to engage and disengage a catch, and horizontal motion to tighten the latch and catch against each other when the latching mechanism is engaged and to separate the latch and catch when the latching mechanism is disengaged to allow opening of the container.

Abstract: The tape module for mounting in a mailing machine includes a tape track supported by a support means such that the tape track is supported in a generally cantilevered manner. A tape positioning means selectively positioning the support means in a first position and in a second position longitudinally removed from the first position. A tape feed means for selectively feeding one of a plurality of imprinting tapes to and through the tape track such that the fed imprinting tape resides within the tape track when the tape track is in the second position.

Abstract: A fastener in which a captive bolt engages a cylindrical nut within a cylrical confining housing. The cylindrical nut has a longitudinal slot in which a pair of oppositely facing latches are disposed and which cooperate with the housing to prevent the rotation of the nut. Rotation of the captive bolt moves the cylindrical nut longitudinally within the housing and operates to extend the ends of the latches to engage a surface or to retract the ends of the latches to within the nut.
