Barrier pads for use in an evaporative cooler unit consisting of a barrier pad mounted on the blower housing and spaced from its intake openings to prevent droplets of moisture and particles of dust which collect on the cooling pads of the unit from being drawn into a room or the like by the cooling unit's fan. The pad may be a ring covered with an absorbent material. The ring is mounted in front of the blower housing openings by wire supports fixed on the stud bolts which secure the fan shaft m...

Absorbent material lined on one side thereof with fluid impervious material is impregnated with an odor imparting substance which attracts young dogs to the pads for the purpose of urination and defecation and discourages chewing of the pad by the young dog.

A flushable wrapper for sanitary napkins and other absorbent pads. The wrapper comprises a non-woven fiber web bonded by cold-water soluble polyvinyl alcohol and subsequently treated with an insolubilizing agent which renders the polyvinyl alcohol resistant to solubilization in a moisture laden environment. A web thus bonded has enough wet strength and abrasion resistance to perform satisfactorily at moisture levels encountered during normal use, yet disintegrates sufficiently fast after soaking...

An air-laid fibrous web is confined between a lower foraminous support member and an upper pad engaging surface having a shape of a fibrous pad to be formed. A pressure differential is established across the foraminous support member for removing unconfined portions of the fibrous web to thereby form a fibrous pad underlying the pad-engaging surface and having substantially the same shape as the pad-engaging surface.

A composite filament reinforced rotor blade having a splayed root construction is provided with a pad on each side of the blade in the area of transition between the airfoil portion and root portion of the blade. The pad is designed to be wedged between the blade and its corresponding disc slot during rotor operation and to transmit blade centrifugal forces from the blade to the disc in such a manner so as to produce a compressive force on the surface of the blade in the transition area for prev...

An endless-chain transport system for a photocopy machine is described for gripping copy sheets at a paper-feed station, transporting the copy sheets past a photoconductive drum while holding surfaces of the copy sheets in close proximity to the drum, and transporting the copy sheets to a copy-sheet-delivery station. The transport system comprises gripper bars mounted on transport chains having gripper jaws which are opened and closed by cams to grip and release the copy sheets. Gripper-bar bump...

Improvements in pads for feminine use, of the type for internal application, said pad comprising a dehydrated pressed cellulose body, of high moisture absorbent characteristics, said body being thin and flat and being straight at one end thereof, said cellulose body being included in the interior of a sheath made of solid jelly which is shaped similar to the interior body, said sheath being circular and rounded adjacent the other end of said body, said jelly dissolving by the thermic action of t...

A pair of laterally and vertically adjustable scoliosis pads are attached to opposite sides of a chair in such position as to provide therapeutic contact with opposite sides of a person seated in the chair for treating curvature of the spine. The pads can be positioned in vertically staggered relationship to develop a therapeutic force couple across the seated person's trunk for tending to straighten out the curvature of the spine. A foot rest is attached to the bottom of the chair and two strap...

An anatomically contoured post-extraction pad made by compressing a piece of absorbent material to form an absorbent portion surrounded by a marginal portion of substantially greater density. The marginal portion is cut to generally complement facial contours of teeth adjacent an alveolus or tooth socket, whereby the pad is retained by and between the aforesaid teeth with its absorbent portion disposed in the alveolus. Assemblies of series connected pads may be provided for use in multiple extra...

A portable device for being carried on a person in order to relieve an ear-ache pain; the device consisting of a heating pad placable against the ear and being connected by wiring to either to a household electric outlet or else to a dry cell battery and switch than can be carried in a pocket so the person is thus free to move about either in the home or out-of-doors.
