Abstract: A leak detection and shut-off system designed to detect a liquid leak or excess moisture at key locations in a piping system. The system includes a wireless detector comprising a sensor and transmitter which sends a signal to a receiver. The receiver triggers a control board to activate the closing of a valve to stop the flow of the liquid into the internal system or a block of a closed system.

Abstract: A printing press is provided which may be adapted to print in multiple colors on paper or film. The press can then laminate film-to-film, laminate film-to-paper, or apply a PVA adhesive or cold seal adhesive to the substrate in line. The press is provided with a CPU and a plurality of motors each of which drives an individual roller, i.e. a printing station roller, a nip, or the rewind roller, and a plurality of sensors which monitor the speed of the laminate and substrate, the tension of the laminate in substrate in various places. In response to the signals received from the sensors, the CPU individually controls the motors to maintain the printing stations in registry with each other.

Abstract: A separator for separator a paper ply from a polymer or other ply of heterogeneous, multi-ply packaging materials subjects the packaging materials to high pressure liquid delivered from a plurality of rotating nozzles. The packaging material is delivered into the chamber from a pre-wetting or soaking station. The nozzles in the chamber separate the paper from the polymer and reduces the paper to fibers. The polymer is skimmed off the top of the chamber in which the material is treated. The water and pulp are delivered to a settling tank where the paper fibers settle and water is removed. The remaining liquid and the paper fibers are delivered to a centrifugal screw where the remaining water is removed from the paper.

Abstract: A microwaveable food container is provided with an accessory which contains a heat assist to facilitate heating of the food. The accessory is secured to the container along two opposite edges of the accessory and is provided with perforations which allow the metallized heat assist to be easily removed. The remaining portion of the container may therefore be recycled.

Abstract: A method of treating yard waste includes introducing yard waste into a chamber wherein the yard waste is impinged by high pressure jet of liquid; the liquid from a group of rotating nozzles. The pressurized liquid stream breaks down the yard waste to create a greater surface area for biological microorganisms to attack, thereby speeding up the decomposition of the waste.

Abstract: A microwavable food product package comprises two separate parts: a bag in which the food is packaged, and an accessory which is placed over a face or wall of the bag. The accessory has a fully metalized surface with a pattern of metal free areas formed in the metallization. The pattern is formed to resemble the break-up or fretting of a continuous unbroken layer of metal when it is heated by microwave energy. The pattern may be formed as a plurality of rows of S's which criss-cross he accessory, or it may be a tight grid pattern of thin lines of unmetalized areas.

Abstract: A microwavable food product package comprises two separate parts: a container in which the food is packaged, and a sleeve which fits around the container. The sleeve includes selected areas upon which microwave interactive material (a metal layer) is printed. The sleeve is fitted over the food package such that the interactive material is in line with the food contained in the package. The metal layer, in line with the food, assists in the heating of the food.

Abstract: A continuous method of forming a repetitive pattern on a metallized film substrate is disclosed as including the steps of continuously feeding a web of metallized film substrate at a predetermined web speed, selective dry removal of predetermined metallized areas from the metallized film substrate during continuous movement thereof, and collecting metallized dust and flakes removed from the metallized film substrate during the aforementioned dry removal of predetermined metallized areas from the metallized film substrate. Unlike existing wet systems which remove metallized areas from a metallized film substrate, the present invention employs selective dry removal, along with the collection of dust, in a continuous in-line system. Following the selective removal of metallized areas from the metallized film substrate, metallized dust is collected in a closed dust removal system providing removal, transport and collection of the metallized dust in a storage unit.

Abstract: A microwavable package incorporating controlled venting, including a bag formed of a series of walls, the front, back, side gusseted, and bottom walls, with the walls being of the type formed of a series of laminates constructed of at least a pair of laminar materials, forming at least an inner and outer layer for the structured bag, a vent chamber provided between select of said laminates to afford a controlled venting of the cooking generated pressure and steam from the interior of the bag to its exterior during a cooking process, at least one vent passage provided through the inner laminar material within the region of the disposed vent chamber, said vent chamber extending to the exterior of the bag, whereby during the heating of an item within the bag its generated pressure and steam enters into the vent chamber by way of the vent passage and is released exteriorly of the bag during cooking, while maintaining the integrity of the package and its upper seal during the process.
