Specifically, the liner is adapted to reinforce the cabinet to achieve this objective.

Abstract: A high pressure sealing assembly for a device having a rotatable shaft. The assembly includes a stationary seal member associated with the device which has an opening generally conforming to the rotatable shaft, a rotatable seal member adapted to be mounted on the rotatable shaft to engage and cooperate with the stationary seal member, and a rotatable seal collar adapted to be mounted on the rotatable shaft to engage and cooperate with the rotatable seal member. With this arrangement, the rotatable seal collar cooperates with the rotatable shaft to maintain the rotatable seal member in engagement with the stationary seal member.

Abstract: A retainer for a shelf including a barrier member. The barrier member is adapted to be supported by the shelf and releasably secured to the shelf in at least two positions of adjustment including an article retaining position and an article access position. With the barrier member secured in the retaining position, articles are prevented from inadvertently falling from the shelf.

Abstract: A sealing assembly for a device having a rotatable shaft. The assembly includes a stationary seal member associated with the device which has an opening generally conforming to the rotatable shaft and a rotatable seal member adapted to engage and cooperate with the stationary seal member for effecting a seal therebetween, the rotatable seal member being adapted to be mounted on the rotatable shaft for rotational movement therewith. With this arrangement, the rotatable seal member is also adapted to engage and cooperate with the rotatable shaft for effecting a seal therebetween.

Abstract: A sealing assembly, kit and method for rotatable shafts. The assembly includes a stationary seal member having an insert receiving opening dimensioned larger than a rotatable shaft, an insert member having an enlargeable shaft-receiving opening adapted to be mounted in the insert-receiving opening in the stationary seal member, and a rotatable seal member adapted to be mounted on the rotatable shaft to engage and cooperate with the insert member. The kit is similarly composed of the same elements but with a plurality of each such element having differing sizes to accommodate rotatable shafts of different dimensions.

Abstract: A device for testing the integrity and strength of a seal. The device includes a first enclosure member adapted to receive a pre-sealed package formed of two films joined together to form a continuous seal, the two films extending outwardly of the seal to define a marginal edge portion of the package. A second enclosure member adapted to cooperate with the first enclosure member upon demand is also provided to seal the marginal edge portion in spaced relation to the continuous seal of the pre-sealed package. The device also includes a fluid injection member adapted to cooperate with the first and second enclosure members by injecting a fluid between the two films after the marginal edge portion of the pre-sealed package has been sealed. An opening located outwardly of the continuous seal of the pre-sealed package and inwardly of the seal created by the first and second enclosure members is provided through which the fluid may be injected between the two films of the package.

Abstract: A rotary wing aircraft is disclosed and includes a fuselage, a gas turbine engine operated air compressor within the fuselage, and a jet nozzle driven rotor assembly situated over the fuselage and having a rotor axis about which the assembly rotates. The rotor assembly includes a generally hollow rotor hub and a plurality of generally hollow jet nozzle driven rotor blades extending radially outwardly of the rotor hub. The rotor hub defines air conduit means to the rotor blades. A section of at least one rotor blade comprises a foldable flexible air conduit for folding the rotor blade in a radial plane relative to the rotor hub. Releasable stabilizing means, including a droop stop, is disposed between the rotor hub and an outboard portion of the rotor blade beyond the flexible air conduit section, whereby the stabilizing means may be released and the blade folded in its radial plane with the flexible air conduit section acting as a hinge.

Abstract: A knockdown metal table having legs and a flanged top and including auxiliary components such as a drop leaf and modesty panel having attaching means which in assembly are clamped between the legs and the table flanges. A lift assembly including casters is attached to the legs and is adapted to be selectively actuated to move first one pair of casters and then the other into or out of engagement with a floor surface to permit rolling of the table over said floor surface or to rest the table on the floor surface in a desired position.

Abstract: A process for improving the photoelectric properties of a laminated charge image carrier. In the process, a coating composition is prepared containing an insulating material which is doped by admixing a sensitizer and a coating of the doped composition is applied to a substrate to form a doped insulating layer. A photoconductive layer containing the sensitizer is then applied to the doped insulating layer.

Abstract: A lamp shade assembly kit includes an assembly ring formed of flexible material into a closed loop, a hoop formed of rigid material and a cover member formed of flexible material into a continuous, open-ended configuration. The assembly ring has an enlarged hoop-receiving channel opening inwardly about the periphery thereof. The cover member is adapted to be secured to the assembly ring. The hoop can then be inserted into the enlarged channel in the assembly ring to give a selected shape to the assembly ring and cover member. With these features, the lamp shade assembly kit may be shipped and stored in knockdown condition and quickly assembled without tools in any of a wide variety of shapes and sizes with optional decorative trim selections.

Abstract: A lockable closure for a container having an annular lip advantageously has locking means whereby the closure can be releasably locked to the container. The closure has at least an annular portion adapted to be disposed in contact with a portion of the annular lip of the container, and preferably also an annular wall adapted to contact a portion of a wall of the container to provide a sealing engagement therewith. The locking means generally comprises shoulder means for lockingly engaging the annular lip of the container and bending means adjacent the shoulder means for deflecting the shoulder means about the annular lip of the container. The closure is useful with containers formed of various materials, for example, of both metal and molded plastic.
