Title: Processes and systems for making synthetic bulked continuous filament yarns
Inventor: WADDINGTON DAVID M
IPC: D01F6/60
Filed: 2001-06-18
Abstract: Processes and apparatus are provided whereby the morphology of bulked continuous filament (BCF) yarns can be variably controlled. More specifically, according to the present invention, the BCF yarn is melt-spun, 'drawn and textured, most preferably in a one-step spin-draw-texture (SDT) process, wherein prior to texturing, the yarn is subjected to a differential temperature condition. Most preferably, such differential temperature condition is accomplished using the duo rolls employed in drawing the BCF, such that one of the rolls is maintained at a greater temperature as compared to the other of the rolls. Most preferably, it is the upstream-most roll (relative to the general conveyance path of the filament toward the texturizer) which is the hotter of the duo rolls.

IPC: A63F9/00
Filed: 2001-06-18
Abstract: Whipps Table/Board Game is an indoor or outdoor game depending on where the player(s) want(s) to be. It is played on a TABLE ar BOARD using miniature whips and Pivot wedges. The Pivot wedge is whipped by a player towards one goal. The challenge player whips the Pivot wedge towards the opposite direction. The strands are wound round the Pivot wedge, Pivot wedge is laid flat on the table and whisked forward, followed by more whips. Or, the said is positioned on the throne stand and given a forward whip followed by more whilaping to produce speedier spinning. The difference between this game and Pivot Whipping Game Reg. No. 2,311,148 is that we have advanced this to the level of being played on a Table or Board by those people or Players who for health reasons cannot bend to whip, or cannot run fast on ice or on smooth flat surface. The player tries to maintain the Pivot spinning on its thin end until it passes through the goal objects as designed. still spinning. if the Pivot lies on its sloppy side, or on its flat surface, it is a foul. One, two, or more players can play the game. But more than two players, they would have to be calling in their own teammate to replace them while they rest, with the Pivot is still spinning.

Title: Turbocharger with nozzle ring coupling
Inventor: ZAGONE JOHN R
IPC: F01D9/02
Filed: 2001-07-03
Abstract: A turbocharger includes a rotor having coaxial turbine and compressor wheels. In a preferred embodiment, a turbine inlet scroll conducts exhaust gas toward the turbine wheel and an exhaust duct carries exhaust gas away from the turbine wheel. A turbine nozzle ring coupled between the inlet scroll and the exhaust duct defines an annular passage including angled stator blades and vanes that direct gas angularly against energy converting blades of the turbine wheel. Ring seals at outer and inner edges of the nozzle ring inlet end seal the inlet end against loss of gas pressure. They may also form springs that axially bias the nozzle ring against a stop to fix the axial position of the nozzle ring. The nozzle ring is centered by radial guides at the outlet end which may include at least three radial keys on the nozzle ring engaging mating guide slots connected with the exhaust duct. The guides maintain axial alignment of the nozzle ring and an integral shroud with the rotor axis while accommodating relative thermal growth of the connected components.

Abstract: A technique for maintaining a continuous fire in a stove or fireplace for an indefinite period of time which is best accomplished by utilizing a reticulated altering device or grid. When an ongoing fire is subsiding because the fuel is near depletion, the burning materials, the burned materials and the burnable materials contained in the fire can be separated with the grid, the burned materials passing through the apertures of the grid and the burning and not yet burned materials remaining on top of the grid for deposit at a desired location in the fire burning area. The burned materials are removed from the fire burning area and the burning and burnable materials are re-stoked to sustain and continue the fire. The grid can be substantially flat with a hanging and holding handle for convenience. Approximately 95% of the burning materials remain in the stove and do not ultimately reside in an ash can utilizing the present technique, thus providing an added safety factor.

Abstract: A document reader for optoelectronically illuminating, reading and interpreting (i.e. processing and analysing) indicia appearing on a document in a machine readable zone thereof, wherein the indicia is made visible only under illumination by non- visible light (i.e. UV or IR). UV (or IR) light sources (LED's) of the reader are rapidly switched to a stable, peak UV (or IR) illumination frequency or frequency range to illuminate and render visible such covert UV-visible (or IR-visible) indicia. An optoelectronic image sensor (CCD) captures the document image, which includes the indicia rendered visible by the UV source illumination, and the covert indicia is identified from the captured image. An optical path, being folded by two mirrors so as to provide a compact geometry for the reader, extends between a reading surface on which the document is place and the image sensor. A lens configured for focussing light defining an image onto the sensor is provided in the optical path. The reader may also include bank(s) (array(s)) of visible light sources (LED's), for illuminating visible indicia, in addition to UV and IR LED arrays and any IR light sources may also be used for illuminating visible OCR characters according to ISO 1831. A controller is provided to sequentially activate each different light source bank.
