A modular fuel cell cassette for use in assembling a fuel cell stack comprising a metal separator plate and a metal cell-mounting plate joined at their edges to form a hollow cassette. A fuel cell subassembly is attached to the mounting plate and extends through an opening in the mounting plate. The plates include openings to form chimney manifolds for supply and exhaust of fuel gas to the anode and air to the cathode. A conductive interconnect element extends from the fuel cell subassembly to make contact with the next cassette in a stack. The anode openings in the mounting plate and separator plate are separated by spacer rings such that the cassette is incompressible. A fuel cell stack comprises a plurality of cassettes, the mounting plate of one cassette being attached to, and insulated from, the separator plate of the next-adjacent cassette by a dielectric seal surrounding the interconnect.

Disclosed is a weighting agent comprising processed taconite, and methods of applying the weighting agents during the completion of subterranean wells. The processed taconite is ground such that the particle-size distribution is comparable to and compatible with other suspended solids in fluids such as, but not limited to, drilling fluids, lost-circulation-control fluids, spacer fluids, cement slurries and temporary pills.

A washing machine includes an on-axis balancing fluid injection system for correcting an out-of-balance rotating inner tub or spinner. The laundry appliance includes an outer tub having molded thereto a plurality of fluid delivery channels into which are arranged a pair of stationary balancing fluid injectors which selectively dispense the balancing fluid into either a front or rear injection zone of the inner tub. Upon activation, the injectors discharge an amount of balancing fluid into a nozzle assembly which is positioned to re-direct the balancing fluid into select pockets arranged about the front and rear injection zones. The injectors discharge the balancing fluid near a hub portion of the rotating inner tub so that the fluid is dispensed at an area of low velocity.

A method and apparatus for filtering pressure data from a pressure-sensitive device is disclosed. A computer implemented method for filtering pressure data from a pressure-sensitive device comprises receiving, from a pressure sensitive device, a raw pressure value for a stroke, filtering the raw pressure value for the stroke to determine a filtered pressure value, and computing a width of a stroke based on the filtered pressure value.

A data analysis system is proposed for providing fine-grained low latency access to high volume input data from possibly multiple heterogeneous input data sources. The input data is parsed, optionally transformed, indexed, and stored in a horizontally-scalable key-value data repository where it may be accessed using low latency searches. The input data may be compressed into blocks before being stored to minimize storage requirements. The results of searches present input data in its original form. The input data may include access logs, call data records (CDRs), e-mail messages, etc. The system allows a data analyst to efficiently identify information of interest in a very large dynamic data set up to multiple petabytes in size. Once information of interest has been identified, that subset of the large data set can be imported into a dedicated or specialized data analysis system for an additional in-depth investigation and contextual analysis.

A washing machine includes an out-of-balance correction system having a plurality of injector valves each having an associated solenoid element. Each of the injector valves is adapted to selectively inject a balancing fluid into a pocket carried by an inner tub to offset the out-of-balance condition. The valves are rapidly and repeatedly cycled to achieve a timed dispensing of the balancing fluid. To reduce the effects of the repeated cycling on the solenoid, a cushion element is mounted to a rear portion of a plunger carried within a solenoid coil. Additionally, a texturing process is applied to a pole piece arranged within the solenoid coil to establish a controlled leakage of air from a central portion of the cushion element once the plunger contacts the pole piece. With this arrangement, the service life of the injector valve is increased and proper control and timing of the injector valve is assured.
摘要:
A washing machine is provided with an out-of-balance correction system which can sense an out-of-balance condition of an inner tub during a washing cycle. More specifically, the correction system supplies an amount of balancing fluid to one or more receiving pockets formed in the inner tub about front and rear injection zones of the inner tub. Stationary injectors are provided to selectively dispense the balancing fluid through molded passages extending between an outer tub and the receiving pockets.

Devices for use with wireline sheaves are provided that allow for capturing grease freed from a wireline as it passes around an upper sheave during wireline retraction from a wellbore. Once the freed grease is captured, it is reapplied to the wireline as it passes from the upper sheave to the lower sheave where the grease may be captured for disposal.

Methods and apparatus, including computer program apparatus, implementing techniques for processing digital artwork. In one aspect, the techniques process aggregations of artwork where both the aggregation and at least some of the aggregated artwork have attached styles. The techniques handle various combinations of conditions resulting in applying style elements to the aggregation before or after applying style elements to underlying artwork. In another aspect, the techniques implement editable path objects having multiple attached fills and/or strokes. The techniques provide user interfaces for using the foregoing features.
