Patent CA-2093016-A1 (CA)
Inventor: HAGER DONALD G
IPC: A62D3/00
Filed: 1992-07-31
Abstract: An oxidation chamber used for irradiating an incoming liquid containing unwanted organic pollutants has a structure that facilitate automatic self-cleaning at intervals. A modular construction is used, and three basic types of modules (12, 14 and 16) are employed. One of the modules (16) is a TEFLON~lined carbon steel pipe through which a shutting scraper is forced at interval. The shuttling scraper includes an annular wiper (60) that simultaneously cleans the inside surface of the surrounding tubular module ( 16) as well as the outside surface of an enclosed quartz tube (36). The annular wiper sealingly engages the quartz tube and the tubular module so that it is driven like a piston by the full pressure of the liquid. When the shuttling scraper has reached the end of the tubular module, it parks itself in a position that causes only minimal pressure drop.

Title: Apparatus and methods for intermittently applying discrete adhesive coatings
Inventor: RATERMAN JOHN
IPC: B05C5/04
Filed: 1993-06-28
Abstract: Abstract of the Disclosure:         Apparatus   and   methods for   producing intermittent, discrete patterns of coating material, such as hot melt adhesive, onto discrete substrates or substrate areas, such as book spines, sift-proof carton flaps and pinch-bottom bags.   The adhesive patterns have sharp, square leading and trailing edges, as well as side edges.  A slot nozzle die has elongated air slots  along the  slot  extrusion opening.    In  the operation of the apparatus, the air flow is initiated from both air slots prior to the initiation of the hot melt flow.  Also, the air flow is continued beyond that point in time, when the hot melt flow ceases.   The delays between the operations of the air flow and the hot melt flow are on the order of micro seconds.    Coating weights down to 1 gram per square meter at about  350  meters  per  minute  substrate  speed  are provided.  Alternatively, the lead and lag air start and stop times on each side of the film of coating material are different to control the exact disposition of the square cut-on and square cut-off coating edge on the substrate.

Filed: 1994-03-31
Abstract: ABSTRACT          System and Method for Packaging Bales of Hay and an Improved Wrapping Apparatus A system for packaging hay bales includes a press for compressing hay to small, compact bales and a wrapping machine which applies multiple sheets of a thin material to form a package of an effective strength that maintains the form and integrity of the hay bales, and prevents them from expanding back to their pre-compressed size. The wrapping machine applies the thin film to successive compressed hay bales such that the material extends therebetween to integrate multiple hay bales into a common bundle. A partial cutting machine positioned downstream of the wrapping machine cuts a portion of the material between adjacent hay bales to provide a detachable seam. A full cutting machine positioned downstream of the partial cutting machine completely cuts thematerial between selected pairs of adjacent wrapped hay bales to define sets of multiple wrapped hay bales.
