Abstract: The present invention relates, generally, to a method and apparatus for electrowinning metals, and more particularly to a method and apparatus for copper electrowinning using the ferrous/ferric anode reaction and a flow-through anode, such as, for example, a dimensionally stable carbon, carbon composite, metal-graphite, or stainless steel anode. In general, the use of a flow-through anode—coupled with an effective electrolyte circulation system—enables the efficient and cost-effective operation of a copper electrowinning system employing the ferrous/ferric anode reaction at a total cell voltage of less than about 1.5 V and at current densities of greater than about 26 Amps per square foot (about 280 A/m2), and reduces acid mist generation. Furthermore, the use of such a system permits the use of low ferrous iron concentrations and optimized electrolyte flow rates as compared to prior art systems while producing high quality, commercially saleable product (i.e.

Abstract: An ink jet printer including a printer cartridge containing a printhead attached to a cartridge carriage for translation of the cartridge across a print media. The printer also includes an off carriage ink supply, a printer microprocessor, and a combined ink fill tube and electrical connection cable connected between the cartridge and the off carriage ink supply for providing refill ink to the ink cartridge and control of the carriage and printhead. Improvements to the printer enable low cost, high quality printing to be achieved.

Abstract: A laser beam position sensing arrangement using two similar sensors where, instead of the first sensor being aligned normal to the beam scan path, the angle which bisects the two sensors is aligned normal to the beam scan path. The average of times T1 and T2 at which the laser beam is incident the respective sensors is used for the horizontal or start of scan value, and the difference (T2−T1) is proportional to the vertical or process direction value. From the difference between the two determined times, the longitudinal beam position may be determined.

Abstract: Datawords encoded using a first-order Reed-Muller code are decoded using a Fast Hadamard Transform (FHT). Where the dataword is known to comprise a number of unused bits at one end, the soft decisions of the codeword are reordered. Majority polling is then performed on groups of the soft decisions to produce a series of soft decisions which make up a new codeword. The new codeword is then decoded using an FHT of lower order than the FHT applicable to the originally received codeword.

Abstract: A multifunctional, self-contained towable backhoe apparatus adapted for direct over-the-road trailering by a towing vehicle, has a support frame having a front and a rear, and a trailering hitch attached to the front. Wheels support the frame at the front and the rear. The rear wheels can function as drive wheels. A backfill blade is movably attached to the rear of the frame. An articulated arm assembly is pivotably mounted on the rear of the frame. A stabilizer with a street pad, a spade, or both, can be secured to the front of the frame for stabilizing the apparatus while in a digging position. The movable backfill blade is capable of movement to a raised position for supporting the articulated arm during transport and movement to at least one lowered ground-engaging position capable of stabilizing the apparatus, of earth moving, or a combination thereof. One end of the articulated arm is adapted for attachment of a tool, including a digging bucket, a pavement breaker, an auger, a grapple, or a fork.

Abstract: An n-bit serial shift register in an ink jet print head operates in a print mode or a test mode. When the shift register is operating in the print mode, n bits of print data are serially scanned into n number of bit registers and are then latched out to heater addressing logic circuitry in the print head to control a print operation. When the circuit is operating in the test mode, x bits of test point data from x number of test nodes in the print head are loaded in parallel into x number of the n number of bit registers, and are then serially scanned out to a test data output. In this manner, a single shift register may be used to scan in print data and scan out test data, thereby providing observability and controllability of the internal logic nodes of the print head while minimizing logic size and the number of input/output connections on the print head.

Abstract: A multifunctional weld fixture is provided having a base receiving a component and a plurality of locator tabs disposed around its outer edge. A circumferential array of expansion feet are movably attached to the top surface of the base. A disk-shaped wedge is disposed in sliding engagement with the expansion feet. A cover supports a portion of the component and seals against the component to create an enclosed plenum. The same fixture may be used to expand the component to compensate for shrinkage after the weld is compete.

Abstract: A system is described for compensating for misalignments in an ink jet printer having an ink jet print head cartridge that includes a heater chip. The system includes determining alignment adjustment information related to the misalignments in the ink jet printer, loading the alignment adjustment information into a volatile memory device on the heater chip, and accessing the alignment adjustment information from the volatile memory device. The system also includes generating nozzle control signals based at least in part on the alignment adjustment information. The nozzle control signals are selectively provided to resistive heating elements in the heater chip, thereby heating ink in ink chambers adjacent the heating elements and ejecting ink droplets toward a print medium. The timing of the nozzle control signals is adjusted based upon the amount of misalignment in the various components of the printer and print head.

Abstract: An inkjet printhead position detection system includes a light emitting device emitting at least one beam of light having a first edge and a second edge nonparallel to the first edge. An inkjet printhead includes a light detecting device detecting the at least one beam of light as the inkjet printhead scans across the light. A time period between when the light detecting device crosses the first edge of the at least one light beam and when the light detecting device crosses the second edge of the at least one light beam is dependent upon a position of the inkjet printhead.
