Title: Compositions comprising fused particulates and methods of making them
Inventor: CASTLE RICHARD B
IPC: C03C1/00
Filed: 1995-04-24
Granted: 2007-01-16
Abstract: The disclosure describes a method for producing bulk, particulate material that includes solid, generally ellipsoidal particles by dispersing irregularly shaped feed particles including about 60 to 100 % by weight of at least one silicate-containing material selected from among wollastonite, alkali feldspar, plagioclase feldspar and nepheline. While maintaining the feed particles in dispersion, they are heated sufficiently to bring about at least partial fusion within at least the surfaces of the particles. This produces a bulk particulate product of which about 15 to 100 % by volume is generally ellipsoidal particles. Also described are compositions of matter including solid particles, at least a portion of which are substantially glassy and generally ellipsoidal.  At least a portion of these particles have been respectively formed from feed particles composed substantially of at least one silicate selected from among wollastonite, alkali feldspar, plagioclase feldspar and nepheline. The bulk particulate compositions contain about 15 to 100 % by volume of the substantially glassy, generally ellipsoidal particles that are products of at least partial fusion of such feed particles.

Abstract: A thermal imaging device  (10)  includes a detector (50) having a linearly-arrayed plurality of spaced apart detector elements (50') upon which portions of a viewed scene are sequentially scanned by a scanner (22) in order to capture image information from the scene.  A display device  (22, 62, 66)  similarly includes a first linear array of plural spaced apart light emitting diodes (LED's) (62') which provide light scanned by the same scanner (22) to a user of the thermal imaging device (10) to provide an image replicating the viewed scene.   The LED's (62') of the display (22, 62, 66) are configured so that sequential portions  of  the  image  are  interlaced  and  partially overlapped by the scanner (22) to provide a flat visual field which is free of raster lines.  The display device (22, 62, 66) includes a second linearly-arrayed plurality of  symbology  LED's  (198)  which  are  configured  and positioned relative to the first plurality of LED's (62') so that light from these LED's is interlaced but not overlapped and so that symbology imagery presented by the second plurality of LED's  (198)  is superimposed on the scene image presented to the user of the thermal imaging device (10).

Title: Continuous filament yarn with pixel color effect
Inventor: COONS ANDREW M III
IPC: D02G1/16
Filed: 1997-01-07
Granted: 2003-07-29
Abstract: Multiple (at least two) differently colored or colorable feed yarns are fed from their respective yarn packages to a multi-position interlacer manifold assembly. The feed yarns are maintained separate and apart from one another and are passed in this separated state through individual interlacer jets associated with the interlacer manifold assembly. The individual yarns are thereafter conveyed to a conventional yarn processing system (e.g., an apparatus known colloquially in the art as a "Gilbos" apparatus) where they are entangled with one another to provide a finished yarn in which the individual yarn components remain substantially coherent throughout the finished yarn. The individual interlaced yarns thus become entangled with one another when subjected to the yarn processing system without substantial inter-yarn blending or commingling occurring (which blending or commingling would thereby cause the constituent yarns to become nearly indistinguishable from one another). That is, each of the interlaced feed yarns will retain substantially its individual coherent identity in the final entangled yarn product so that its associated color is capable of being visually perceived along the length of the yarn-i.e., as color "pixels" in the yarn.

Title: Apparatus for applying an apex filler to a bead ring
Inventor: MARABITO MARK
IPC: B29D30/48
Filed: 1997-01-17
Granted: 2006-01-03
Abstract: The assembly applies an apex filler to the outer circumferential surface of an annular bead ring. The apex filler applying assembly incorporates an apex filler applicator that is preferably operable in conjunction with a plurality of server mechanisms. One server mechanism is a conveyor that receives a bead ring. A locator operates in conjunction with the conveyor to position the annular bead ring precisely on the conveyor so that it may be engaged by a transfer mechanism. The transfer mechanism removes the bead ring from the conveyor and mounts it on a chuck turret assembly. A chuck head in the chuck turret assembly engages the bead ring and accurately positions the bead ring relative to applying rollers in the apex filler applicator, in which position the apex filler -which has been directed from an extruder through an orienting mechanism, into an in-feed mechanism and severed to length by an in-flight guillotine cutter -is applied to the annular bead ring. After the apex filler has been applied to the bead ring the transfer mechanism removes the finished tire bead sub-assembly from the chuck head and deposits the tire bead sub-assembly on the conveyor for removal from the assembly.

Title: Reduced keyboard disambiguating system
Inventor: KING MARTIN T
IPC: G06F3/033
Filed: 1996-07-26
Granted: 2000-11-14
Abstract: A reduced keyboard disambiguating system (50) having a keyboard (54) with a reduced number of keys. A plurality of letters and symbols are assigned to a set of data keys (56) so that keystrokes entered by a user are ambiguous. Due to the ambiguity in each keystroke, an entered keystroke sequence could match a number of words with the same number of letters. The disambiguating system includes a memory (104) having a number of vocabulary modules (110). The vocabulary modules contain a library of objects that are each associated with a keystroke sequence. Each object is also associated with a frequency of use. Objects within the vocabulary modules that match the entered keystroke sequence are identified by the disambiguating system. Objects associated with a keystroke sequence that match the entered keystroke sequence are displayed to the user in a selection list (76). The objects are listed in the selection list according to their frequency of use. An unambiguous select key (60) is pressed by a user to delimit the end of a keystroke sequence. The first entry in the selection list is automatically selected by the disambiguating system as the default interpretation of the ambiguous keystroke sequence. The user accepts the selected interpretation by starting to enter another ambiguous keystroke sequence. Alternatively, the user may press the select key a number of times to select other entries in the selection list. For words that are not in the vocabulary modules, a two-stroke or multiple-stroke method are used to unambiguously specify each letter. The disambiguating system simultaneously interprets all entered keystroke sequences as a word, as a two-stroke sequence, and as a multiple-stroke sequence. The multiple interpretations are automatically and simultaneously provided to the user in the selection list.

Abstract: A modularly-partitioned feedforward multicarrier linear RF power amplifier is described. The circuitry and components of the power amplifier are segregated into physically-separate modules in accordance with several criteria. In one embodiment, the power amplifier is segregated into a RF power module, a linearizer module and a DC power supply module. The RF power module includes power- and frequency- dependent components and generally varies with the carrier frequency and output power requirements for a specific application. The linearizer module includes circuitry and components that are substantially power- and frequency-independent. As such, the linearizer module is substantially invariant and a single design may be used for virtually any application. The DC power supply module includes circuit and components that are substantially frequency independent but somewhat power dependent. The DC power supply module may vary from amplifier to amplifier where there is a significant change in output power requirements.
