Title: A vacuum apparatus having textured clothing for controlling the rate of application of vacuum pressure in a through air drying papermaking process
Inventor: BUENGER DANIEL EDWARD
IPC: D21F1/52
Filed: 1997-08-29
Abstract: A papermaking vacuum apparatus having a web-facing surface adapted to support a papermaking belt and comprising a head, a body and at least one vacuumslot disposed in the head and defining an aperture on the web-facing surface. The vacuum slot is in fluid communication with the web-facing surface and extends from the web-facing surface to the body which is in further fluid communication with a vacuum source. The web-facing surface has a textured clothing interposed betweenthe web-facing surface of the vacuum apparatus and a backside of the papermakingbelt. The textured clothing creates leakage between the backside of the papermaking belt and the web-facing surface of the vacuum apparatus and effectively eliminates the vacuum seal between these two surfaces. In one preferred embodiment, the textured clothing comprises an endless belt adapted to travel around the vacuum apparatus.

Patent CA-2231324-A1 (CA)
Title: Induction load balancer for parallel heating of multiple parts
Inventor: HALDEMAN CHARLES W
IPC: H05B6/44
Filed: 1996-08-28
Abstract: The load balancer incorporates link coil circuits that inductively couple to induction heating coils, which are connected in parallel across a power source. A capacitor is electrically connected in the link coil circuit. By varying degree to which the link coil is inductively coupled to the heating coil or by changing the capacitance, either using a variable capacitor or switching among different capacitors, changes in the amount of reactance coupled into the heating coil are effected. Thus the current in the corresponding heating coil can be varied, enabling adjustment of the heating of the workpiece. Accordingly, the resulting system is efficient since only a single coil rather than multiple series coils are used. This aspect can be enhanced when litz cable is used in coil construction. Further, the system is compatible with active control.

Title: Methods for manufacturing molded sheets having a high starch content
Inventor: HODSON SIMON K
IPC: B29C48/09
Filed: 1997-04-09
Abstract: Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler.  Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, a cellulosic ether, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties.  The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the cellulosic ether to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation. The starch and cellulosic ether form the binding matrix of the sheets with the fibers and optional inorganic filler dispersed throughout the binding matrix. The starch-bound sheets can be cut, rolled, pressed, scored, perforated, folded, and glued to fashion articles from the sheets much like paper or paperboard. The sheets are particularly useful in the mass production of containers, such as food and beverage containers.
