Abstract: A self adhesive bandage which comprises a hydrophilic gel located on a bandage carrier strip at the point of the strip to be positioned against a wound. Portions of the same surface of the carrier strip are also coated with a pressure sensitive adhesive, allowing the bandage to be secured to the skin. The gel-side surface is covered with a strip of removable release paper until the bandage is to be used, in order to preserve its sterility. The gel comprises water and a polyol mixed with the reaction product of a bis crosslinking agent with an acrylamide compound.

Abstract: A process for fabricating label feed stock laminates that comprise label face-paper substrate sheets covered with a layer of pressure-sensitive adhesive film in which the adhesive film is protected by a sheet of release-paper until the label face-paper substrate is to be fastened to a desired surface. The process involves extruding a pressure-sensitive adhesive in the form of a vertical tubular film whose shape is maintained by air pressure; thereafter collapsing the tube into a flat film by passing it through the nip of draw rolls, and then combining the adhesive film with the face-paper and the release-paper to form the desired laminate by passing both of the latter two through the draw rolls simultaneously with the adhesive film.

Abstract: A continuous process for fabricating strips of gel-coated, self-adhesive bandages in which a laminate comprising a release paper strip fastened to a bandage strip whose lateral wound-side surfaces are coated with a pressure-sensitive adhesive is withdrawn from a feedstock roll and passed over a delamination roll where the two strips are separated. The release paper strip is then passed over an embossing roll where it is longitudinally scored, while a gel composition is simultaneously deposited on the middle portion of the bandage strip. The two strips are thereafter forwarded to a relamination roll at which point they are united in a relamination, and sent to a die-cutting roll where the desired bandage shape is cut into the bandage strip. The die-cut relaminate is thereafter forwarded to a delamination roll where the selvedge is removed, leaving a strip of the desired bandages.

Abstract: A seawall barrier comprising a relatively massive elongate wire cable reinforced concrete structure with a shank and diverging feet that has reinforcing cables embedded in the structure barrier and being threaded through a reinforcing member at the feet portion of the structure.

Abstract: The solar heated building comprises a flexible tube of transparent plastic sheeting adapted to be positioned on, or secured to, a building or anchor unit so as to form the top cover therefor, a pair of shafts engaging spaced internal portions of the tube and extending longitudinally thereof, the tube having closed ends and being positioned to move peripherally, rollers engaging the plastic sheeting and forcing it against the shafts, whereby, on drive of the rollers, the flexible transparent tube can be moved around its periphery, the transparent tube having at least one longitudinally extending section therein with a reflective metal flexible layer thereon, whereby, when the reflective metal layer portion of the tube is so positioned on the roof or cover unit as to receive the sun's rays thereon, they are reflected whereas the flexible plastic tube can be moved around its periphery to have only transparent plastic sheeting receive the sun's rays for transmission of the light's rays therethrough to transmit he

Abstract: A method of making a prestressed concrete pole, including placing a heat softenable plastic pipe in a metal tube or pipe and filling the space between the pipes with concrete, rotating the metal pipe-concrete assembly rapidly to center the plastic pipe therein, applying hot fluid pressure to the interior of the plastic pipe, longitudinally prestressing the concrete pipe assembly for several hours while the concrete sets, and gradually releasing the fluid pressure and prestressing pressure to obtain a prestressed concrete pole.

Abstract: A portable structure for use in building pipelines and the like including an inflatable flexible elongated structure having sides and open ends, support track means operably engaged with each side of said structure and extending the structure length, and a plurality of anchor means or assemblies thereof, each including a device to engage the track means, a part of the anchor means engaging the ground to hold the structure against vertical upward movement, but permitting relative movement between the track means and the anchor means so that the structure can be operatively positioned by the anchor means but be movable in relation thereto.

Abstract: The windmill includes a vertically positioned support shaft, a plurality of elongated, molded arcuate plastic vanes which are vertically positioned and operatively connected to the support shaft, which vanes are slightly flexible so winds engaging the vanes will flatten the arc of some vanes and will make the arc of other vanes tighter to provide unbalanced rotational forces on the vanes, and means operatively connect to the shaft to provide power therefrom on shaft rotation.
