Abstract: A firestopping apparatus for providing a fire barrier in a construction barrier. The apparatus is comprised of a sleeve within which there are located intumescent pads that are oriented to form a confinement area therebetween to accommodate various penetrating members such as cables, conduits and the like that need to pass through the barrier. Upon sensing the heat from a fire, the intumescent pads seal around the penetrating members to prevent the fire from passing through the barrier. One or both of the intumescent pads is movable toward or away from the other so that the confinement area can be adjusted in size, that is, the confinement area can be increased in size to accommodate a large number of penetrating members of decreased to accommodate a lesser number. One or both of the intumescent pads may be biased in the direction toward decreasing the size of the confinement area.

Abstract: A bracket for holding of cylindrical tanks such as emergency breathing tanks adjacent to a wall surface or behind a seat surface in a detachable manner with positive engagement released by an operative release line. An upper and lower securement strap are secured together at an engaging tab which straps extend around the tank when the tab is engaged and can be easily released for rapid exit. A webbing extends between the upper and lower securement straps for minimizing any entanglements or catching of the straps on protruding portions of the tank.

Abstract: A mechanical bracket for positively engaging of a generally cylindrical tank such as an SCBA tank in an inverted position mounted to a planar surface such as within the back of a fire truck seat. The apparatus includes a uniquely configured top clamping member which is pivotally mounted to selectively engage the upwardly facing bottom of the tank as well as including a bumper immediately thereadjacent which is adjustably positionable for abutment with the lower end of the tank which is facing upwardly. A uniquely configured foot plate is provided having a tank receiving zone defined therewithin for holding of the upper valving area of such tanks. A unique locking mechanism and release mechanism is also provided.

Abstract: A multi-part mounting assembly for securing a plurality of individual pathway conduits relative to one another extending through a wall panel between adjacently positioned wall studs including two support members extending parallel to one another and defining therebetween a pathway conduit zone for receiving the individual conduits along with end members for providing sealing at the outermost edges and one or more partitioning means securable at a plurality of discrete positions within slots defined in the support members and being securable with respect to the support members and including set screws for safely holding pathway conduits in position extending therethrough.

Abstract: A self-adjusting firestopping apparatus for holding of intumescent material within poke-through openings in construction barriers usually being floors but also possibly being walls or ceilings wherein cables or other penetrating members extend therethrough. The self-adjusting apparatus includes a sleeve with the intumescent material centrally located therein and preferably two plates extending along the sleeve and movably attached thereto by a flexibly resilient support device such as a coil spring or flat spring. This plate provides a movable false panel which is adapted to expand responsive to the placement of increasing numbers of penetrating members extending therethrough to increase the capacity of the intumescent firestopping device.

Abstract: A hard disk drive comprises an actuator with independently movable arms and a printed circuit board with custom core electronic architecture. The drive also comprises one or more platters aggregating two or more platter surfaces whereupon data may be read from or written to by corresponding read/write heads. The independent-arm actuator and custom printed circuit board enable alternate or interleaving bits or blocks of data to be read or written simultaneously across a plurality of platter surfaces within the same physical drive.

Abstract: The present invention provides an incentive for buying a ring binder or a spiral notebook. The incentive is provided by having the binder or notebook include one or more internal folded sheets, preferably in the form of poster panels, which may be disposed within the binder or notebook and thereafter removed and, in the case of multiple sheets, unfolded for display separate from the binder or notebook. The poster panel or panels may coordinate with artwork on the cover of the binder or notebook.

Abstract: A cam cleat particularly usable for securing laces of footwear which is easy and quick to assembly making use of a base member with vertically extending studs including vertical slots defined therein to facilitate the studs flexing inwardly to a smaller diameter to facilitate placement of engaging caps on the studs with the respective locking rims of the studs being engageable into locking grooves defined in the mated surfaces of the engaging caps. In this manner the caps can be snapped onto the mounting studs merely by exerting downward pressure thereon with a return spring held in the proper position.

Abstract: A double articulating hook lifting apparatus usable mounted upon a truck or trailer for loading and unloading containers with respect thereto and also being usable for dumping the containers. The locking mechanism operates to secure a movable arm to the pivot frame 2 to stop pivotal movement relative to one another, which also facilitates the movement required for dumping of the contents of the container while mounted on the vehicle. The Locking device is automatically allowed to move to the locked position by the movement of the jib away from the arm, preferably in a telescoping manner. This movement occurs as the last step in the sequence of container loading to thereby automatically provide locking between the arm and the pivot frame 2 to prevent pivotal relative movement therebetween whenever the container is in the loaded position or is in dumping mode.
