摘要:
A pumpable slurry of mineral particles, e.g., coal, in water contains 50 to 85% by weight of mineral particles based on the combined weight of mineral particles and water. The mineral component contains at least 30% by weight of coarse particles having a particle size in the range 5 to 50 mm, 10 to 40% by weight of fine particles having a particle size less than 200 micron and the balance to 100% of intermediate sized particles.The slurry is stable without the use of additives and can be pumped through a pipeline.

A measurement device, such as a laser radar, is described that comprises a transmitter portion for transmitting radiation to a remote probe volume, a receiver portion for detecting radiation returned from the remote probe volume and a processor for analysing the detected return radiation. The device is suitable for transmitting and receiving radiation through a window portion having associated window cleaning apparatus (e.g. wiper 62) for cleaning said window portion in response to a cleaning activation signal. The processor is arranged to generate a cleaning activation signal for activating window cleaning apparatus when the properties of said detected return radiation are indicative of a reduction in transmission through at least part of said window portion. In one embodiment, a conically scanned lidar is described that generates a cleaning activation signal when the power of detected return radiation varies as a function of the angle of transmission of radiation from the device.

A method of seismic retrofitting a concrete structure includes removing material from a portion of the concrete structure by irradiating the portion with a laser beam having a laser energy density. The method further includes positioning a stabilization structure in proximity to the portion of the concrete structure. The method further includes attaching the stabilization structure to the portion of the concrete structure, whereby the stabilization structure provides structural support to the concrete structure.

摘要:
A method of performing periodic maintenance on a printhead in an ink jet printer, includes the steps of: applying electrical power to the ink jet printer at a start time; determining an elapsed time since the start time; comparing the elapsed time with a determinate time period; and performing a printhead maintenance routine, after the elapsed time reaches the determinate time period, and independent of usage of the printhead.
摘要:
A digital processor for simulating operation of a parallel processing array incorporates digital processing units (P.sub.1 to P.sub.8) communicating data to one another via addresses in memories (M.sub.0 to M.sub.8) and registers (R.sub.11 to R.sub.41). Each processing unit (e.g. P.sub.1) is programmed to input data and execute a computation involving updating of a stored coefficient followed by data output. Each computation involves use of a respective set of data addresses for data input and output, and each processing unit (e.g. P.sub.1) is programmed with a list of such sets employed in succession by that unit. On reaching the end of its list, the processing unit (e.g. P.sub.1) repeats it. Each address set is associated with a conceptual internal cell location in the simulated array (10), and each list is associated with a respective sub-array of the simulated array (10). Data is input cyclically to the processor (40) via input/output ports (I/O.sub.5 to I/O.sub.8) of some of the processing units (P.sub.5 to P.sub.8). Each processing unit (e.g. P.sub.1) executes its list of address sets within a cycle at a rate of one address set per subcycle. At the end of its list, each of the processing units (P.sub.1 to P.sub.8) has executed the functions associated with a conceptual respective sub-array of simulated cells (12), and the processor (40) as a whole has simulated operation of one cycle of a systolic array (10). Repeating the address set lists with further processor input provides successive simulated array cycles.
摘要:
A lift is provided for a personal watercraft and includes two relatively elongated channel members each of a generally C-shaped transverse cross-section. A carriage carrying a platform upon which the personal watercraft can be supported is mounted for sliding movement between the elongated channel members through a cable, winch, reversible electric drive motor and associated gears and pulleys. When the carriage is located within the upper channel member, the latter, the platform and the personal watercraft can be swung about a vertical axes to rotate the personal watercraft between two different positions 180.degree. removed.
