摘要： A mechanism for vertical adjustability and securement of a backrest of a chair on the upright support of the chair having a housing which includes first and second housing members, and a pair of link assemblies, pivotally connected and movable between a locked position and an unlocked position. A resilient sleeve is carried by one of the link assemblies and is engageable against the upright support when the link assemblies are in the locked position to grip the upright support between the sleeve and a rod to prohibit vertical movement of the housing with respect to the upright support.

摘要： An adapter for use with a gas filter canister worn by a user as part of a breathing apparatus. The adapter is constructed of a semi-rigid plastic that has a plurality of scalloped or castellated edges. The scalloped or castellated edges allow the adapter to snap-fit over the top of the canister. Projections or lugs on the inside of the edge of the adapter can deflect and snap over the rim of the canister. An adapter seal in the form of a large preformed packing or O-ring, is pressed between the inside of the adapter top and the outside of the canister top such that an airtight seal is formed. The adapter is capable of moving relative to the filter canister to accommodate different positions of the flexible conduit between an adapter inlet and the outlet of a self contained blower assembly.

摘要： A filter cartridge assembly including a replendam that combines a particulate filter with an irregular shaped gas sorbent bed. Best operational practice requires that the air passing through the filter be distributed uniformly over the sorbent bed. The repledam directs the air over the surface of the larger sorbent bed utilizing vane-like structures extending from the reticulated member providing for uniform distribution.

摘要： A protective covering for annular objects, such as caster wheels, which covering consists of a continuous band of heat-shrinkable plastic material defining spaced marginal edges thereabout, which band is proportioned thereabout to be closely received over and about the tread of the caster wheel in overlapping relation to the wheel along both side edges of the wheel tread, for heat shrinking thereagainst, whereby the band is tensioned against the wheel tread, and the wheel tread side edges, in protective relation to the tread, which band is formed to provide what becomes a tear or release strip that functions to sever the band, when removal of the covering is desired, from one side edge of the band to the other. When removal of the covering from the wheel tread is desired, the tear strip is created by pulling or peeling a designated portion of the covering laterally outwardly of the wheel tread, and from one side edge of the covering to the other side edge of same, to sever the protective covering, which covering then springs free of the wheel tread. A method is disclosed for application of the protective covering over the wheel tread.

摘要： A bearing assembly comprising a roller mechanism and a cage member. The roller mechanism includes a plurality of roller members and a plurality of frangible connector links for initially connecting each roller member to an adjacent roller member. The roller members and the connector links are integrally molded together. The cage member includes a circular flange and a plurality of spacer pegs extending perpendicular from the flange in a circular configuration. The pegs are spaced apart from one another and each peg includes a tip having a hollow chamber adapted to receive and store a connector link. The pegs are adapted to be inserted between adjacent roller members during assembly such that when the cage member and the roller mechanism are pressed together, the pegs will sever the connector links from the roller members and will retain the severed connector links in the chambers of the peg tips. The severed roller members are then free to independently rotate within the cage member.
