Title: Process for making particulate compositions
Inventor: BEDELLS ALISON DAWN
IPC: C08J3/00
Filed: 1999-03-23
Granted: 2008-02-19
Abstract: There is described a process for producing a particulate composition comprising the steps of: (a) forming a first dispersion comprising first particles stabilised in a first fluid by first species; (b) optionally the step of forming a second dispersion comprising second particles stabilised in a second fluid, miscible with the first fluid, by second species; (c) after (or simultaneously with) the optional step of mixing the first and second dispersions together if the second dispersion was formed from step b); inducing association between the dispersed particles to form clusters; and (d) binding together the particles within the clusters; characterised in that the first and/or second particles comprise at least one polar functional group to facilitate the binding of the particles in step (d). Preferably the polar group is other than an acid group, more preferably comprises at least one hydroxy group, non-acidic polar group and/or non-basic polar group, most preferably comprises one or more hydroxy and/or ether groups (e.g. an optionally polymeric alkylene glycol alkyl ether). A preferred embodiment of the process comprises mixing together two aqueous dispersions of particles (e.g. pigment particles and particles of hydroxy functional latex polymer). The dispersions are stabilised with surfactants. Association of the particles into clusters is induced by known means (e.g.  heating and stirring) and the clusters are grown by aggregation into loose matrices which are more fused together to form particles which can be used in electroreprographic toners.

Abstract: A dense media cyclone and a classification cyclone are disclosed. The cyclone (1) comprises a body (2) having a circumferential side wall (3) extending between an upper end (4) and a lower end (5) and defining an interior space (6). The side wall (3) comprises an upper wall portion (8) an d an adjacent lower wall portion (9) of traditional frusto conical configuration. The upper wall portion (8) defines an inlet and the lower wall portion (9) defines an underflow outlet (18). A vortex finder (20) projects substantiall y axially into the interior space (6) and defines an overflow outlet (21). The vortex finder (20) and upper wall portion (8) define a feed zone within the interior space (6) of decreasing cross sectional area from the inlet (10) to the internal end (22) of the vortex finder (20). In addition, the wall of the vortex finder (20) tapers outwardly towards its free end and the vortex finder generally occupies a greater portion of the cross sectional area of the body than with prior art cyclones. These features of the cyclone improve cyclone efficiency by decreasing short circuiting flow both to the underflow outlet (18) and th e overflow outlet (21).

Title: Electronic coin checker
Inventor: TRENNER DIETMAR
IPC: G07D5/00
Filed: 2001-05-22
Granted: 2008-04-15
Abstract: An electronic coin checker is proposed which has a coin entry channel, in the region of which a sensor arrangement is disposed, and has a flap-shaped coin switch and a control device. In dependence on the signals of the sensor arrangement, the control device controls the coin switch to accept a coin running through the coin entry channel into an acceptance shaft, or into a return channel to return the coin. The flap-shaped coin switch has a sloping extension inclined towards the runway of the return channel, on which the coin slides away in the return position of the switch, alters its inclination and falls onto the runway of the return channel. The boundary wall, ly- ing opposite the coin switch, of the return channel is configured inclined in the running direction, and thus a further alteration in inclination takes place.

Abstract: A package having a re-sealable seal is formed from a flexible sheet having its opposite longitudinal edge portions sealed together to form a tubular structure with a permanent longitudinal seal. Two permanent end seals are formed transversely across the tubular structure to seal the product inside the package. A re-sealable seal is formed adjacent one of the permanent seals. The re-sealable seal is formed by a pressure-sensitive adhesive applied to a first region of the inner surface of the sheet proximate the one permanent seal and a heat seal coating applied over the pressure-sensitive adhesive so as to cover the pressure-sensitive adhesive, and a heat seal coating applied over a second region of the inner surface of the sheet. The first and second regions of the inner surface are placed in contact with each other and the heat seal coatings thereon are sealed together to initially form the re-sealable seal. When the first and second regions of the sheet are pulled apart upon opening of the package, the pressure-sensitive adhesive separates from the first region and remains with the second region. The second region is pressed against the first region to reclose the package.

Abstract: A method and apparatus for tracing hardware states using dynamically reconfigurable test circuits provides improved debug and troubleshooting capability for functional logic implemented within field programmable logic arrays (FPGAs). Special test logic configurations may be loaded to enhance the debugging of a system using FPGAs. Registers are used to capture snapshots of internal signals for access by a trace program and a test multiplexer is used to provide real-time output to test pins for use with external test equipment. By retrieving the hardware snapshot information with a trace program running on a system in which the FPGA is used, software and hardware debugging are coordinated, providing a sophisticated model of overall system behavior. Special test circuits are implemented within the test logic configurations to enable detection of various events and errors. Counters are used to capture count values when system processor execution reaches a hardware trace point or when events occur. Comparators are used to detect specific data or address values and event detectors are used to detect particular logic value combinations that occur within the functional logic.

Title: Using gain-adaptive quantization and non-uniform symbol lengths for audio coding
Inventor: ROBINSON CHARLES QUITO
IPC: G10L19/032
Filed: 2000-04-11
Granted: 2009-12-08
Abstract: Techniques like Huffman coding can be used to represent digital audio signal components more efficiently using non-uniform length symbols than can be represented by other coding techniques using uniform length symbols. Unfortunately, the coding efficiency that can be achieved by Huffman coding depends on the probability density function of the information to be coded and the Huffman coding process itself requires considerable processing and memory ressources. A coding process that uses gain-adaptive quantization according to the present invention can realize the advantage of using non-uniform length symbols while overcoming the shortcomings of Huffman coding.  In gain-adaptive quantization, the magnitudes of signal components to be encoded are compared to one or more thresholds and placed into classes according to the results of the comparison. The magnitudes of the components placed into one of the classes are modified according to a gain factor that is related to the threshold used to classify the components. Preferably, the gain factor may be expressed as a function of only the threshold value. Gain-adaptive quantization may be used to encode frequency subband signals in split-band audio coding systems. Additional features including cascaded gain-adaptive quantization, intra-frame coding, split-interval and non-overloading quantizers are disclosed.

Abstract: A balance bar for a straight tube Coriolis flowmeter. The balance bar is preferably manufactured by process that provides an increased number of flowmeter elements integral to the balance bar. These integral elements comprise: brace bars at each end of the balance bar, rib elements on each side of the balance bar to raise the lateral vibration frequency, a surface to facilitate the mounting of a driver to the balance bar and to a flow tube surrounded by the balance bar, surfaces to facilitate the mounting of sensors to the balance bar and flow tube, voids that lower the resonant frequency of the balance bar in the drive mode as well as in the second bending mode. An integral mass makes the vibration amplitude of the balance bar less than that of the flow tube. Said element that lowers the resonant frequency of the balance bar in the second bending mode also makes the flowmeter calibration factor independent of density. The balance bar is ideally made by a casting process in which the entirety of the balance bar is formed, but it may be fabricated by any process, including machining, that produces a flowmeter having some or all of the above mentioned elements integral thereto.

Abstract: An electrochemical fuel cell is operated with periodic oxidant starvation. Periodic oxidant starvation conditions cause a change in the potential of the starved electrode and may result in the removal of electrocatalyst poisons and in improved fuel cell performance. This technique may have other beneficial effects at the electrodes, including performance improvements due to water management effects or localized heating effects at the starved electrode.   In a preferred method, while successive localized portions of a fuel cell electrode are periodically reactant starved, the remainder of the fuel cell electrode remains electrochemically active and saturated with reactant such that the fuel cell is able to continue to generate power.
