Title: Preformed flexible laminate
Inventor: BUCHANAN RONALD ELLSWORTH
IPC: B29C48/08
Filed: 1997-02-26
Abstract: A composite structure comprising a preformed flexible laminate in adhering contact with at least a first and second transparent or translucent panel members (22, 23) such as would be useful as an insulated glass unit. The flexible laminate contains an undulating spacer element (25) either partially or totally embedded within a core material (24) and has a polymeric coating (26) on at least one surface thereof. The flexible laminate effectively seals the interior of the panel structure from air and/or moisture and maintains a desired distance between the panels (22, 23). A multi-cavity extrusion die for forming the preformed flexible laminate has a core cavity for receiving the core material (24) as well as the undulating continuous spacer element (25).  Converging walls within the core cavity serve to embed at least one side of the spacer element (25) in the core material (24) and a land area forms a desired shape or configuration wherein the spacer element (25) undulation is maintained. At least one polymeric feed cavity located downstream from said core cavity and said land area applies a polymeric film or coating (26) to at least a surface of the embedded spacer element (25). A plurality of optional feed cavities can apply the same or different polymers to additional surfaces of the embedded spacer element (25) and can totally cover or encapsulate the same.

Title: System and method for generating fractional length delay lines in a digital signal processing system
Inventor: VAN DUYNE SCOTT A
IPC: G10H1/12
Filed: 1997-04-03
Abstract: A sampled data, non-integer delay line interpolation structure (150) includes a sampled data delay line (156), two allpass filters (162, 164), each having an associated read pointer (158, 160) for reading data at a corresponding integer position of the delay line, an alternating crossfader (166) that alternatingly crossfades between the outputs of the two allpass filters, plus a controller (154) that controls when the read position of each allpass filter is updated and also controls when the filter coefficient of each allpass filter is updated. A specified delay length value is sampled by the controller each time the crossfade orientation of the alternating crossfader is changed, and from that value the controller generates a new read pointer and filter coefficient for allpass filter to which the structure will next crossfade.

Title: Maltodextrines modifiees chimiquement
Inventor: EDEN JAMES L
IPC: C12P19/14
Filed: 1997-04-30
Abstract: A l'aide d'un procédé de conversion d'amylase alpha riche en solides on prépare des sirops de maltodextrine riches en solides dont certains sont utiles comme base pour des adhésifs ramollissables. Les sirops se caractérisent par leur teneur élevée en solides (au moins 55 % en poids) et leur couleur claire. On utilise comme matière de départ un amidon granulaire chimiquement dérivé et facultativement converti d'un degré de substitution supérieur à environ 0,01 et inférieur à environ 0,5. Les maltodextrines ont une teneur en sucre réducteur d'environ 5 à 19 équivalent dextrose et une distribution distincte de la masse molaire polymodale. Lorsqu'on utilise un amidon granulaire fortement estérifié ID.S de 0,5 à 1.8) comme matière de départ dans le procédé à forte teneur en solides, les maltodextrines estérifiées converties par enzyme résultantes se caractérisent par leur meilleure dispersibilité dans l'eau.

Title: Networked gaming devices using bonus token
Inventor: SCHNEIDER RICHARD J
IPC: G06F19/00
Filed: 1999-04-27
Abstract: A plurality of gaming machines, such as slot machines or the like, are networked together in communication with a bonus server. The bonus server identifies each machine on the network and transmits a bonus token across the network to a machine control interface within a selected one of the machines. The bonus token is preferably a message packet containing the unique address of the gaming machine selected as well as various parameters which govern aspects of a bonus session initiated at the machine. Receipt of the bonus token signal at the machine causes additional lighting and sound effects beyond that enabled by the normal operation of the game. The bonus token also enables additional bonuses within the game that are awarded to a player of the selected machine. At the end of a bonus period, the bonus token is returned to the bonus server, processed to introduce new parameters, and then transmitted to a second one of the plurality of gaming machines. The bonus token is passed in this way from machine to machine to enhance the gaming experience of the lucky player of the selected gaming machine.

Filed: 1999-04-29
Abstract: A multipole rod assembly for guiding an ion stream has a large multipole rod set having relatively large dimensions, and a small multipole rod set having smaller dimensions. One end of the small multipole rod set extends within the large multipole rod set and the other end of the small multipole rod set is located outside of the large multipole rod set, so that fringing effects of fields at the ends of the large and small multipole rod sets are reduced. A second small multipole rod set can be provided axially aligned with the first small multipole rod set, and a second large multipole rod can also be provided with the second small multipole rod set extending within the second large multipole rod set. Where there is a transition between two different fields in adjacent rod sets, the invention enables the volume of the transition zone to be reduced, so as to reduce the likelihood that ions will be lost.

Abstract: An internal natural light delivery system (1) collects light rays (11) through a series of reflective surfaces and redirects the light to an internal area (13) of a building. One embodiment includes a collector (8) which includes a first reflector positioned adjacent to a translucent structure of a building.  Light is reflected upward by the first reflector through a first hollow member (2) which is adjacent to the collector (8). A first elbow (4) including a second reflector (23) is adjacent to the first hollow member (2). Light rays (16) encounter the second reflector (23) and are directed in a horizontal position (17). The light travels through a second hollow member (3) which is adjacent the first elbow (4) and extends into a desired internal space (13) within the building. A second elbow (14) adjacent the second hollow member (3) contains a third reflector (24) to direct the light downward to a diffuser (18).

X = any combination of:     (see formula I) The copolymer may be used in various automotive paint compositions. The resin may be prepared by first synthesizing the desired blocks, the polycarbodiimide blocks and the modifying blocks, then link them together. The resin may also be prepared by forming the polycarbodiimide directly onto the modifying blocks.      The latter approach is the preferred one. The modifying blocks are prepared in the conventional manner for the chemistry and the choice of the modifying blocks depend on the application. For proper topcoat wetting, it is desired that some portion of the modifying blocks be highly polar.
