A lumbar support pad for providing support to a user's back by engagement with the small of the user's back. The pad is preferably formed from a resilient low density foamed material. The back-engaging surface is complexly curved in a convex direction between the lateral edges and in a concave direction between the longitudinal edges.

Compaction wheels are convertible from sheepsfoot configuration to other configurations such as rectangular pads and have rigidly attached peripheral shanks for mounting removable, wear-cap holders equipped with replaceable, abrasion-resistant metal wear-caps. In certain embodiments the wear-cap holders are secured rigidly to the wheel periphery.

Apparatus for forming fibrous pads include a pad-formation assembly having spaced, three-dimensional pad-receiving compartments; adjacent compartments being separated by air-impermeable regions. Each compartment has the shape of a fibrous pad to be formed therein and is defined by a lower air-permeable surface and air-impermeable sidewalls extending outwardly from the air-permeable surface. Sidewall sections are movable relative to the lower surface to aid in releasing formed pads from each of t...

A foldable sharps disposal pad having a layer of polyurethane on a layer of cardboard, part of the polyurethane foam having a pressure sensitive adhesive thereon. The latter is in the form of a polyester film having a tacky styrene-butadiene rubber adhesive layer on each side.

A method of applying multi-colored visible matter to a side surface of a pad or block of sheets of paper by a transfer printing process wherein a substrate having multi-colored inks thereon is applied to the side surface and heat and pressure are then applied to the substrate in order to transfer the inks to the side surface of the pad or block of sheets.

A device for positioning a patient in a chair having a back and arms. The device includes a pad for placement against the patient and a clamp which underlies an arm of the chair and is shiftable along the length of the arm independently of the back. The pad is connected to the clamp by a series of connecting members which permit universal swinging of the pad about a plurality of angularly disposed and laterally spaced axes. The pad also is mounted for shifting laterally of the attaching clamp an...

A disposable pad for use with a surgical instrument having a supporting element. The pad includes a flexible elongated member having a channel therein for slidably receiving the supporting element. A stop member limits longitudinal insertion of the supporting element into the channel, a retention member prevents lateral movement of the supporting element out of the channel, and a latching member secures the supporting element against longitudinal displacement from the channel. The latching membe...

A cleaning tool for polishing pads, the tool divided at the front end to journal a transverse roller whose periphery has a plurality of headed studs. The tool is tubular with said end directing a nozzle toward the roller; and the rear end has a valve for connecting a compressed-air supply and a finger-operated lever for controlling the valve, whereby to blow an air jet against the periphery of the roller.

In a cleaning, scrubbing or polishing pad of the type formed from a pliable, flexible foamed plastic body having a scrubbing surface, the improvement of a plurality of protuberances on the scrubbing surface, each of the protuberances being defined by peripheral surfaces generally perpendicular to and forming generally sharp edges with an upper scrubbing surface of the protuberance.

A pneumatic pad has two opposite covers of flexible material joined at their margins by a marginal area to form a hermetically sealed hollow space between them. The covers each contain reinforcing cord inserts. At least one cord insert of one of the covers is laid across the marginal area of the pad and extends to the other cover to overlap a portion of the cord insert of the other cover. A valve attachment to connect the hollow space to a source of compressed air is provided.
