Abstract: A container fixant applicator configured to complement target fixing zones of a container. Caulk is introduced into a container, over portions of the container intended to be fixed. The caulk is activated, flowing between the target surfaces. The caulk cures, fixing the container. The wafer substantially retains its configuration during the fixing of the container. The wafer is configured so that it may not pass through the pour spout of a gable top-type container. Methods for producing and applying the container fixant applicator are also provided.

Abstract: A method of improving heat-seals for polyolefin polymers which are coated onto a paperboard substrate. The method obviates the need for use of a curable bonding agent. The materials are exposed to high energy radiation prior to formation of the heat seal to induce crosslinking of the poller and thereby increase the average molecular weight of same.

Abstract: A release liner based stock for use as a carrier web including a paper substrate having an upper surface and a lower surface. A release agent is coating on the top of the upper surface. The unique soap-based acrylic layer discourages curling of the base stock release liner, fiber pick-off contamination from the uncoated side of the paper substrate, and maintains a consistent peel off force required for removing a label from the release liner and deploying it on a target object.

Abstract: A degradable agricultural ground cover which is composed of high density polyethylene polymer fiber and cellulose pulp which is 100% photo and biodegradable for use in weed control and moisture retention in soil. The unique agricultural mat or cover lasts 8-12 weeks before serious photo and biodegradability occurs, while allowing crop plants sufficient time to mature and produce. The sheet totally disappears with plowing and tilling, becoming a soil extender until complete degradation occurs.

Abstract: A rack and screen assembly for converting gas grilles into charcoal and/or wood burning stations. The assembly is fabricated from high temperature stainless steel, so that the assembly, when heated to its cooking temperature, retains such elevated temperature for an extended period of time. The rack includes an open frame with runner legs at its lower end, that sit atop the cylindrical tubes of conventional gas grilles. Braces extend transversely across the open frame to reinforce same, and ledges are defined at the upper ends of the open frame. The perforated metal screen is inserted into the upper end of the frame until the screen rests upon the ledges. When the screen is damaged, or wears out, the damaged screen is lifted out of the frame and replaced, manually, in a simple fashion and without resort to manual tools.

Abstract: Coating formulations, unique methods for their production and use, which have high drying capacity, maintain high levels of brightness, even after the application of a wax coating onto the printed substrate. Precipitated amorphous silicates, titanium dioxide, and other fillers are combined and coated onto heavyweight linerboard to facilitate ink drying and minimize brightness loss associated with wax dipped cartons.

Abstract: This invention embodies the process and apparatus for applying a fluorocarbon coating or film to a metal or other material surface of a substrate, and particularly for applying such coating to the hull of a ship, or to other objects to be submerged in fresh or saltwater, to protect their surfaces from corrosion, and/or from fouling by marine organisms, and to improve the aqueous slip of a vessel during the period the object will be exposed to either aqueous, atmospheric, or other environments; and to protect virtually any substrate surface from virtually any environmental or man-made hazard. This process utilizes a laser that generates an infrared laser beam, such as, but not limited to a carbon derived gas type laser, to assist in the preparation for and attachment of a film or coating to a prepared substrate surface.

Abstract: A plastic seal including: a body to which is connected at least one cord, provided with at least one end with a hook; an aperture provided in the body for insertion of the hook; a seat for housing the hook inserted into the aperture; a means for the irreversible retention of the hook to the body and a pair of closure plates applied to the body.

Abstract: An apparatus is disclosed for harvesting seed which includes a frame and a housing defining a seed box and having a rotary brush mounted on a forward portion thereof which is connected to link bars which are in turn connected to the frame. Corresponding pairs of link bars are attached between the frame and housing on opposite sides of the apparatus, the link bars on each side being substantially parallel to each other. Means are provided for varying the angle of the link bars to the frame, the link bars operationally functioning as a parallelogram to raise or lower the housing at a constant angle relative to the frame. A draw bar is pivotably connected to the front of the frame and tilt angle adjustment means are provided to vary the angle between the frame and the draw bar thereby providing an independent means for varying the angle of attack of the rotary brush to the plants from which seed is being collected.

The unique product forms a guidepath on a carpet which requires little or no maintenance. The product will cause no carpet discoloration or will it be affected by extended exposure to sunlight.

Abstract: The present invention relates to a biodegradable paperboard-based package for various food products. The package utilizes a novel heat-sealable laminate structure wherein the exterior gloss heat-sealable layer is a degradable polymeric resin material such as a polyvinyl alcohol resin or a starch based low density polyethylene polymer resin. Utilization of the material in a novel fashion accelerates the paperboard substrate's degradative properties and tendencies.

Abstract: A switchmode DC to AC converter, and particularly a master-slave half-bridge converter. The slave half-bridge power converter is controlled by a lower power self-oscillating half-bridge master converter. More particularly, the invention pertains to a high frequency ballast for gas discharge devices, especially, for high pressure sodium lamps, completed by a high voltage ignition apparatus.

Abstract: A curved log to be sawn lengthwise by a vertical saw blade is supported for a time, near its center of gravity, by a device which permits the log to rotate about its axis, and thus find an orientation at which the plane of the curve of the log axis is vertical, so as to maximize yield from the log. The device also includes drive sprockets which operate, at certain angular positions of the device, to move the log lengthwise.

Abstract: Several embodiments of ammunition supply indicating systems for firearms are disclosed. Each system (1) counts, either automatically or manually, the number of rounds in a magazine introduced into the firearm, (2) detects the movement of a reciprocally movable slide in the firearm to increment a count of "one" for the round entering the firing chamber, and (3) electronically combines the two digits, and (4) displays same on a display panel. The display panel is situated in a thin housing secured to the firearm along the line of sight of the user. A running total of the number of rounds remaining in the firearm is visible to the user. Slide movement may be detected by magnetic, mechanical, optical, or electrical devices, while the number of rounds remaining in the magazine may be monitored by position switches operated by the follower within the magazine.

Abstract: A dual ovenable paperboard based structure which contains a food contact resin layer. The resin layer in direct contact with the ovenable food product exhibits superior food release properties, grease and oil resistance, and resistance to warpage even after extended periods of time following oven heating. The unique laminate is formed via coextrusion coating techniques on conventional coextrusion equipment at conventional temperatures. The resulting product has a high degree of adhesion between the paperboard and the polymethylpentene food contact layer, and is capable of being utilized for forming pressed or locked corner food trays which can be subjected to oven cooking temperatures.
