Title: A method and apparatus for reeling a wound web roll
Inventor: ADAMSKI BRIAN C
IPC: B65H18/26
Filed: 1994-04-28
Abstract: A method and apparatus for reeling a traveling web, such as paper produced on a paper-making machine, includes a pair of spaced, horizontally disposed rails for supporting one or more reel spools. One of the reel spools is rotated to bring it up to machine speed. A support drum is moved translationally substantially vertically from beneath the rotating reel spool to engage it along a nip line of contact. The on-coming web is directed into the nip of the rotatably driven reel spool to begin the web reeling process to build a wound web roll. The support drum remains in contact with the wound web roll building upon the reel spool continuously until the desired wound web roll diameter is attained. The reel spool/wound web roll is maintained under the control, or influence, of three forces at all times during the formation of the wound web roll: 1) torque from a drive attached to the reel spool, 2) nip pressure from the support drum, 3) web tension of the web coming onto the driven reel spool. The support drum preferably partially supports the wound web roll at all times during the reeling process, and the wound web roll remains horizontal on the support rails at all times as the wound web roll is formed.

Title: Methods for dehulling of flaxseed, producing flaxseed kernels and extracting lignans and water-soluble fibre from the hulls
Inventor: CUI WUWEI
IPC: A23K10/30
Filed: 1996-01-24
Abstract: A dry process for dehulling has been developed in order to utilize all components of flaxseed. The dehulling process is composed of three steps: first the flaxseed is dried, then broken (milled) and fractionated by air classification to produce a hull fraction and a kernel (embryo) fraction. Three drying methods, including oven drying, microwave drying and fluid bed drying, were optimized for efficiency of removing moisture by response surface methodology (RSM) and suitability for the dehulling process. Of the drying methods tested, fluid-bed drying appeared most suitable for the dehulling process with satisfactory drying efficiency. Finally, an optimized flaxseed dehulling process consists of drying of the seeds using fluid-bed dryer, milling by barley Pearler and fractionation of the hull and the kernel (embryo) fractions by air classification. The yield of flaxseed hulls and kernels obtained by the optimized process were 22.6% and 72.2%, respectively. The chemical composition of the hulls was carbohydrates 48.3%, proteins 16.8%, crude oil 26.5%, moisture 5.0% and ash 3.5% compared to that of the embryo fraction (carbohydrates 22.0%, proteins 23.9%, crude oil 47.7%, moisture 3.6% and ash 3.8%) on dry base. Lignans and flaxseed gum are extracted sequentially from the hull while the kernels, purified by sieving, are used as a food and/or feed ingredient with or without further processing.

Title: Cyclone separation of gaseous fluid flows
Inventor: JARVENPAA VILJO
IPC: B01D45/12
Filed: 1994-10-25
Abstract: Method and apparatus for improving the separation efficiency of a cyclone separator intended for gaseous medium flows in which an incoming gaseous medium flow to be cleansed is directed into the cyclone separator through an inlet duct such that the incoming medium flow takes a downward, revolving flow movement inside the cyclone separator until the incoming medium flow reaches a bottom end of a conical lower part of the cyclone separator, and then becomes a revolving tornado flow that flows in a generally-upward direction opposite to the direction of the downward, revolving flow movement. An outlet flow of cleansed gaseous medium is directed through a center pipe situated in the cyclone separator. A component-flow pipe is arranged in the center pipe such that the component-flow pipe has an inlet opening in a wall of the center pipe. A component flow of the incoming medium flow is passed from a location within the cyclone separator through the inlet opening in the wall of the center pipe into the component flow pipe directed out of the component-flow pipe, against the tornado flow, such that the component flow disintegrates the tornado flow and thereby prevents solid matter from being carried along with the tornado flow through the center pipe into the outlet flow of the cleansed medium flow.

Inventor: GELLERT JOBST ULRICH
IPC: B29C45/26
Filed: 1996-07-05
Abstract: Multi-cavity injection molding apparatus having four nozzle manifolds mounted in a common plane with a central inlet manifold having two arms extending in opposite directions. The central manifold has a longitudinal axis extending in a first direction through the two arms. Each nozzle manifold is offset from the central manifold in a second direction that is substantially perpendicular to the longitudinal axis. Each nozzle manifold has a locating pin to locate it in a second direction perpendicular to the first direction. The locating pin allows thermal expansion to slide the nozzle manifold in the first direction into a position wherein each branch of the melt passage is aligned with the melt bore through one of the nozzles extending from the nozzle manifold. A pair of the nozzle manifolds are connected on opposite sides of each arm of the central manifold by connector bushings. Each connector bushing is sufficiently slidable to absorb thermal expansion in the second direction which allows the locating pin to be used to locate each nozzle manifold in the second direction. Thus, the combination of the connector bushing and the locating pin allow sufficient movement of the nozzle manifold in both the first and second directions to provide for thermal expansion of the heated manifold relative to the cooled mold.

Title: Dynamic bias for orbital yam steering
Inventor: RODDEN JOHN J
IPC: G01C21/24
Filed: 1997-01-02
Abstract: A method and apparatus for steering a low-earth-orbit communication satellite requiring sun-orientation for solar-power accumulation is disclosed.  Momentum-bias both maintains nadir pointing and adds yaw-steering moments for sun-tracking attitude control, simultaneously.  The method has two principal steps: 1) open-loop momentum decoupling, for correcting the calculated steering torque, and *closed-loop attitude compensation, to correct for perturbations about the calculated attitude in accordance with one of two control law definitions. This combines the advantage of stable gyroscopic attitude control with those of open-loop yaw steering.

Title: Method, reagents and kit for diagnosis and targeted screening for retinoblastoma
Inventor: DUNN JAMES M
IPC: C12Q1/6886
Filed: 1995-07-07
Abstract: Reliable and cost effective testing for mutations in the RB1 gene can be accomplished by: (a) quantitatively amplifying exons of the sample RB1 gene using primers complementary to intron regions flanking each exon; and (b) determining the lengths and/or quantities of the amplification products for each exon and comparing that length or quantity to the length or quantity of amplification products obtained when a wild-type RB1 gene is amplified using the same primers. Differences in length between an amplified sample exon and the corresponding amplified wild-type exon reflect the occurrence on an insertion or deletion mutation in the sample RB1 gene. Differences in quantity reflect the complete absence of an exon, or heterozygosity for a mutant exon.  Next, the nucleic acid sequence of each exon found to contain an insertion or deletion mutation is determined, or of all exons in the event no insertion or deletion mutations are identified. Preferably, the amplification of the exons is multiplexed so that more than one exon is amplified in a single vessel using sets of primers which provide gene fragments of distinctive lengths when used to amplify a normal RB1 gene.
