IPC: H04N1/405
Filed: 1997-09-04
Abstract: A method building a tile of pixels usable by a marking routine in a raster output device to mark an output device pixel according to a sample value.  The method includes the steps of receiving the sample value in a rendering process; deriving, from the sample value, a base value and a fractional tile of pixels; and building the pixels of the tile by adding the base value to the corresponding pixels of the fractional tile.  The fractional tile may have a bit depth of one.  The invention also features building a chunky color tile by deriving, from a sample color, one component base value for each color component; obtaining a component fractional tile for each color component of the sample color; and building each pixel in the chunky color tile as the composition of the sum of the component base values and the component fractional tile pixel values for the corresponding color components and pixel position. The component fractional tiles can be stored in a packed representation.  The chunky color tile can have four color components.  The invention also builds a pixel in chunky color tile by deriving, from a sample color, a base pixel in a device color space; obtaining a fractional tile for each component of the sample color; forming an addend from all the fractional tiles; and building the chunky color tile pixel by adding the addend to the base pixel.

Title: Amplifier, signal source circuit and power supply
Inventor: SCHMIDT CHRISTIAN
IPC: H03F3/20
Filed: 1997-09-12
Abstract: An amplifier for amplifying a bipolar ac signal having a rectifier with its input coupled to the ac input signal for producing at its output a unipolar pulsating dc signal with the half waves of the ac bipolar input signal being shifted in phase by 180 . The amplifier circuit is coupled to the output of the rectifier for amplifying the unipolar pulsating dc signal. A recovery circuit such as an inverter has its input connected to the amplifier output for recovering the bipolar pulsating ac signal from the unipolar pulsating dc signal, and produces an amplified copy of the bipolar ac input signal. The amplifier uses at least one transistor having a dc voltage reference potential applied to its emitter. At least one input circuit has its input connected to the bipolar ac signal, and converts the signal to a unipolar pulsating dc signal for connection to the base of the transistor. The output inverter circuit, connected to the collector and emitter provides a bipolar pulsating amplified ac signal from the amplified, unipolar pulsating dc signal in the form of an amplified copy of the bipolar ac input signal. There is also a power supply for generating a dc voltage from an ac voltage, having a rectifier coupled to the ac voltage on the input side, and a smoothening circuit on its output. The smoothening circuit provides additional secondary dc voltage half waves on the rectifier output from the primary dc voltage half waves which are shifted in time so that they are disposed in the gaps between the primary dc voltage half-wave peaks to fill in the gaps. A further embodiment uses a transistor which has a base system of a complex crystalline macromolecule.

Title: Improvements in or relating to valves
Inventor: ORBELL JOSEPH ROBIN
IPC: F16K31/20
Filed: 1996-08-02
Abstract: There is described a valve arrangement which in one form is an inlet valve (60) or in another form is a dual flush valve (2). The valves may be used in a variety of situations but find particular application in a cistern for providing water to flush a toilet bowl or similar. The valve arrangement (2) comprises a flushing tube (100) or a pair of flushing tubes (14, 18) which can move axially. One end of the tubes (100, 18) is sealed to an outlet (9). The tubes are provided with rings or collars (16, 22) which co-operatively engage with locking edges (48, 50) of floats (40, 44) to control movement of the tubes (100, 14, 18). The floats (40, 44) are mounted off-centre or in a position spaced apart from their respective centres of gravity so that they are free to move under the effects of gravity and the effects of lift provided by buoyancy of the floats. In operation the sequential effects of gravity and buoyancy cause the floats to hold the tubes in position and then release the tubes thereby allowing selective flushing positions.

Title: Tubular container and methods and apparatus for manufacturing same
Inventor: WILLIAMS ALAN D
IPC: B29C65/14
Filed: 1998-02-04
Abstract: A method of manufacturing multi-ply tubular containers for food products is provided including the steps of applying an aqueous adhesive to a surface of a paperboard body ply and then heating the aqueous adhesive to evaporate part of the water content and render the adhesive substantially tacky.  The body ply and a polymeric liner ply having a moisture barrier layer are then passed through a nip to adhere the liner ply to the body ply and are wrapped around a shaping mandrel to create the tubular container.  Accordingly, an advantageous tubular container can be manufactured having a body ply formed of paperboard which is wrapped into a tubular shape to define an inner surface.  The body ply defines a predetermined circumferential length before being wrapped which corresponds to one revolution of the body ply when wrapped in a tubular shape.  A polymeric liner ply is adhered to the inner surface of the body ply and defines a circumferential length equal to that of the body ply prior to being wrapped.  Accordingly, the liner ply is circumferentially compressed when the body ply is wrapped into the tubular shape and advantageously has a wrinkled surface finish after being wrapped which is caused by the circumferential compression of the liner ply .

Title: Inhibiting completion of defrauding calls
Inventor: SMITH DAVID B
IPC: H04M15/00
Filed: 1998-02-09
Abstract: An arrangement for inhibiting the completion on defrauding calls. Calls to certain area codes are sometimes not subject to the kinds of regulations characteristic of U.S. based area codes. The result is that callers are charged an exorbitant fee (frequently several dollars per minute) without realizing that they are incurring such charges. In accordance with applicant's invention, a data base maintains a record of suspected telephone numbers and calls to the suspected area codes are checked to see if the call is to one of the suspected numbers. If so, the caller is warned and can disconnect before the call is completed. Advantageously, possibly for the payment of the fee, callers are saved from making calls with exorbitant charges.

Title: Overpartitioning system and method for increasing checkpoints in component-based parallel applications
Inventor: LORDI ROBERT
IPC: G06F9/46
Filed: 1996-12-11
Abstract: Two methods for partitioning the work to be done by a computer program into smaller pieces so that checkpoints may be done more frequently. Initially, a parallel task starts with one or more input data sets having q initial partitions, divides the input data sets into p partitions by some combination of partitioning elements (i.e., partitioners/gatherers), runs an instance of a component program on each of the p partitions of the data, and produces one or more sets of output files, with each set being considered a partitioned data set. The invention is applied to such a task to create a new, "overpartitioned" task as follows:  (1) the partitioner is replaced with an "overpartitioner" which divides its q inputs into n* p partitions, for some integer factor n; (2) the component program is run in a series of n execution phases, with p instances of the component program bein run at any time. In each phase, each instance of the component program will read one overpartition of the input data and produce one partition of output data; (3) at the end of each of the n execution phases, the system is quiescent and may be checkpointed. A first embodiment explicitly overpartitions input data by using known partitioner programs, communication channels, and gatherer programs to produce overpartitioned intermediate files. The second embodiment dynamically overpartitions input data by arranging for the component programs to consecutively read contiguous subsets of the original input data.

Inventor: DINGSOR ANDREW D
IPC: H04B1/30
Filed: 1997-05-05
Abstract: A method, apparatus and article of manufacture for compensating for carrier frequency error is disclosed. An FM signal is received from an antenna and the received FM signal is provided to receiver. The receiver takes the FM signal at the carrier frequency and outputs a baseband signal. This baseband signal is then processed by a DSP which provides carrier frequency compensation and decoding to produce a data stream that a microprocessor provides to a host device.  Frequency differences between the FM carrier frequency and the frequency used to demodulate the FM signal can shift the DC bias level of the baseband signal. The DSP compensates for such frequency difference by using a receive compensation value and applying it to each received signal sample. When transmitting, data to be transmitted is provided from the host device to the DSP via a microprocessor. The DSP  provides encoding and carrier frequency compensation of the data to provide a baseband signal to a transmitter that modulates the baseband signal to produce an FM signal at a desired carrier frequency. Frequency differences between the desired FM carrier frequency and the frequency used to modulate the baseband signal can produce errors in receiver systems. The DSP compensate for such a frequency difference by using a transmit compensation value and applying it to each encoded signal sample.

Title: Bonding fibrous batts with thermosetting fiber-binders of certain epoxy resins
Inventor: BUCK GEORGE S
IPC: C09J163/00
Filed: 1996-07-08
Abstract: A process is described for producing a bonded, non-woven fibrous batt by the use of a dry, solid, particulate, latent-cross--linkable, thermosetting, fiber-binder. This fiber-binder is an intimate mixture of a solid epoxy resin and a cross-linking agent. The epoxy resin has (a) terminal epoxy groups;  (b) an epoxide equivalent weight of above about 500; (c) a glass transition temperature above about 40 °C; and (d) a melting point above about 70 °C. In the process the fiber--binder contacts the fibers to form a raw batt with the fiber-binder loosely adhering to the fibers of the batt. Then the raw batt is heated to a cross-linking temperature above the melting point of the fiber-binder but below the scorching or melting point of the fibers thereby melting the fiber-binder. The fiber--binder flows to intersections of the fibers and subsequently reacts the cross-linking agent with the terminal epoxy groups of the epoxy resin. This converts the raw batt into a hot cross-linked batt. The hot cross-linked batt is then cooled to room temperature. Batts are also described as is a process for hot molding these batts.
