Title: Strip unwinding machine
Inventor: PLANATA MIREK
IPC: B65H16/10
Filed: 1993-12-17
Abstract: ABSTRACT      A strip unwinding machine is provided for supplying a continuous strip of thin flexible material by unwinding strip from successive rolls thereof.  The strip unwinding machine has a pair of laterally spaced tracks for receiving opposite end portions of a shaft on which a roll of strip is mounted.  A transfer assembly is provided for moving a new roll and shaft along said tracks from a loading position to an unwinding position, a rotatable unwinding roller is located at the unwinding position, and there is means for rotating the unwinding roller.  The transfer assembly is also operable to urge the roll against the unwinding roller and cause the roll to be rotated thereby with consequent unwinding of the strip from the roll.  At least one guide roller is provided to guide the unwound strip around a portion of the unwinding roller and then out of the machine.  A raising assembly is operable to raise a nearly empty roll and shaft at the unwinding position upwardly from said tracks and from said transfer assembly while maintaining engagement of the roll with the unwinding roller to enable a new roll and shaft to be brought to the unwinding position by the transfer assembly, and a cutting assembly is operable to cut the strip from the nearly empty roll when the new roll is brought into engagement with the unwinding roller by the transfer assembly to cause the last portion of the strip unwound from the nearly empty roll to adhere to an initial portion of the strip on the new roll so as to continuously feed strip from the machine.

Title: Color selection by mixing primary toners
Inventor: CHRISTY ORRIN D
IPC: G03G9/08
Filed: 1994-04-15
Abstract: A specified and designated, non-primary color print (imaging) is applied to a substrate (paper) by mixing at least first and second differently colored toner particles having substantially uniform physical characteristics, and introducing them in desired proportions into a fluidized bed. The toner powders are uniformly mixed together in the fluidized bed (as by using rotors in addition to applying fluidizing air to the bed), and then a substantially uniform electrostatic charge (e. g. about +6.5-+8 kV D.C., which can be applied by blades on the rotor) is applied to the bed, and then the electrostatically charged mixture of toner particles is applied to the substrate, to image uniform non-primary color symbols on the substrate. The uniform physical characteristics of the powders are size (the vast majority of particles having a size between about 5 microns and about 25 microns), a resistivity of greater than 10 12 ohm-cm, and a flowability between a predefined minimum and maximum. When utilizing the fluidized bed as according to the invention, slight changes in chemical composition of the toners may be easily accommodated without change in the resulting uniform imaging.

Abstract: ABSTRACT    A method,  device,  and arrangement in a paper machine for regulating the control of the transverse profile or profiles of properties of a paper web produced therein.  Water is removed from the paper web under compression between two forming wires by making use of dewatering and/or forming ribs.   The deflection of the dewatering and/or forming ribs in the transverse direction of the web is regulated thereby affecting the retention profile of the paper web in the cross direction.  By regulating the deflection of the  dewatering  and/or  forming  ribs,  the  transverse  fiber-orientation profile and/or the filler profile of the paper web is influenced through the control of the transverse retention profile of the web.

Inventor: CHAKRABORTY AMIYA K
IPC: G21C9/06
Filed: 1994-08-09
Abstract: A device for passively inerting the gas mixture forming in the reactor containment of a nuclear power plant in an accident situation is proposed, which device is based on the use of chemical substances which react or disintegrate, releasing an inerting gas or gas mixture when a certain temperature of reaction is reached. This device is especially suitable for use in connection with catalytic recombiners for removing hydrogen through oxidatioxi with the oxygen present. The heat resulting from this exothermic process of recombination can be put to use for heating up chemical substances to the required temperature, these having temperatures of reaction that lie above the temperature (approximately 100° C) that develops in the reactor containment in an accident situation.

Patent CA-2151792-A1 (CA)
Inventor: MCKENNY COLIN J
IPC: C10G1/04
Filed: 1995-06-16
Abstract: A process for upgrading a low rank coal and a heavy oil to produce an improved coal product and an improved oil product. First, the low rank coal is dewatered to reduce its moisture content to less than about 4 percent in order to render the low rank coal more oleophilic. Next, the dewatered low rank coal is mixed with a quantity of the heavy oil of between about 15 and 40 percent of the dry weight of the low rank coal so that the heavy oil substantially contacts the low rank coal in order to produce a mixture. The mixture is then heated to a temperature less than the mild thermal cracking limit of the mixture in order to separate hydrocarbons from the mixture and to produce the improved coal product. The hydrocarbons separated from the mixture during the heating step are then collected in order to produce the improved oil product.

Title: Process for making absorbent paper web
Inventor: TROKHAN PAUL DENNIS
IPC: D21F11/00
Filed: 1991-06-14
Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure.  The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits.  The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network.  The papermaking belt is made by applying a coating of photosensitive resinous material to a reinforcing structure which has opaque portions, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions and also through the reinforcing structure.  A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers.  The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source.  Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.
