The invention relates to a method and a device for the production of essentially continuous fine threads made of meltable polymers. The polymer melt is spun from at least one spin hole (5) and the spun thread is attenuated using gas flows which are accelerated to achieve high speeds by means of a Laval nozzle (6). As a result of the specific geometry of the melt hole (4) and the position thereof in respect to the Laval nozzle (6), the temperature of the polymer melt, the throughout per spin hole and the pressures determining the velocity of the gas flow upstream and downstream from the Laval nozzle (6) are controlled in such a way that the thread reaches an internal hydrostatic pressure before solidifying, whereby said thread bursts into a plurality of fine threads.

Well logging apparatus and methods for determining formation resistivity at multiple (>3) depths of investigation. At least one transmitter antenna and at least two receiver antennas are mounted in a logging tool housing, on substantially a common axis. The antennas are untuned coils of wire. Electromagnetic energy is emitted at multiple frequencies from the transmitter into the formation. The receiver antennas, which are spaced apart from each other and from the transmitter, detect reflected electromagnetic energy. Formation resistivity at multiple depths of investigation is determined using only phase differences in the reflected energy at the different frequencies, minimizing false indications of invasion due to mismatch of vertical response with attenuation measurements and also permitting correcting for the effects of varying dielectric constant of the formation. The apparatus minimizes the number of antennas, electronics complexity, required power, and measurement time required to determine resistivity at multiple depths of investigation.

Preferably, a polymer primer layer is interposed between the highly reflective coating layer and an asphalt saturated and coated reinforcing substrate to keep oils and other colored components in the asphalt from exuding into the highly reflective coating layer.

A laser machining equipment for etching grooves in a wall of a mechanical part, or in a connecting rod for a spark ignition engine, includes a fiber optic laser device arranged to supply laser pulses. The fiber optic laser device is controlled so that laser pulses have a peak power of more than 400 W and at least two times greater than maximum mean power of the laser device, and duration of the laser pulses is below or within the nanosecond range of 1 ns to 1000 ns. The fiber optic laser device can be controlled in a quasi continuous wave (QCW) mode, or can be controlled in a Q-switch mode. The selected operating modes increase machining efficiency and produce a groove with an optimum transverse profile, particularly with a small mean radius of curvature at a bottom of the groove which then allows precise subsequent fracturing of the mechanical part with less force.

A hydrogen-rich reformate gas generator, such as a mini-CPO (catalytic partial oxidizer) (36), provides warm, dry, hydrogen-containing reformate gas to a hydrogen desulfurizer (17) which provides desulfurized reformate gas to a major reformer (14) (such as a CPO) which, after processing in a water-gas shift reactor (26) and preferential CO oxidizer (27) produces hydrogen-containing reformate in a line (31) for use, for instance, as fuel for a fuel cell power plant. The expensive prior art hydrogen blower (30) is thereby eliminated, thus reducing parasitic power losses in the power plant. The drier reformate provided by the mini-CPO to the hydrogen desulfurizer favors hydrogen sulfide adsorption on zinc oxide and helps to reduce sulfur to the parts per billion level.

A chip pretreatment process which comprises conveying the feed material through a compression screw device having an atmosphere of saturated steam at a pressure above about 5 psig, decompressing and discharging the compressed material from the screw device into a decompression region, feeding the decompressed material from the decompression region into a fiberizing device, such as a low intensity disc refiner, where at least about 30 percent of the fiber bundles and fibers are axially separated, without substantial fibrillation of the fibers. In a more specific form the invention is directed to a process for producing mechanical pulp, including the steps of fiberizing wood chip feed material in a low intensity disc refiner until at least about 30 percent of the fibers are axially separated with less than about 5 percent fibrillation, and subsequently refining the fiberized material in a high intensity disc refiner until at least about 90 percent of the fibers are fibrillated. In another form the invention combines chip fiberizing with chemical treatments, for improving the pulp property versus energy relationships.
