Patent CA-1063798-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE                This invention relates to a method and apparatus for coating a substrate and, in particular, to a system for automatically controlling the average, minimum, end distribution of coating thickness of material produced in a continuous-coating process.  The application discussed is a continous-galvanizing line.  However, the system can generally be applied to any continuous-coating process with actuators that control the coating thickness and a gauge that measures the coating thickness.  The system provides a means of maintaining a given average coating weight over the width of the sheet while ensuring that a given minimum-coating weight over a spot less than the width of the sheet will also be met.  The system also provides a means for periodic logging of process data such as these average- and minimum-coating weights.  To do this a digital computer is connected to various sensors and devices on a strip line including a gauge for measuring the thickness of the coating. Typically, the computer may be a Westinghouse model P2500 digital process-control computer, and the gauge may be a Nucleonic Data Systems Model 200 zinc-coating gauge.  This zinc-coating gauge uses X-ray type emissions from a radioactive isotope (Americium 241) to measure the zinc thickness on the galvanized product.  Two gauge heads (top and bottom) give independent measurements of the coating on each side of the strip.  The gauge heads are mounted approximately 230 feet (70 m) downstream from the air knives on the first down pass of the cooling tower.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to improved coated tubular hard-surfacing electrodes containing a particulated filler material and methods for manufacturing same.  In the manu-facture of electrodes of this invention, the ends of electrodes are reduced in cross section to frictionally engage said filler material; then the ends are sealed by dip coating in a liquid or slurry, similar to the flux coating composition.  The resultant coating fills the interstices of the filler material.  Thus costly welding of the ends to seal them is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE         A road roller includes a ballast means comprising a chamber of gasproof material, the chamber having one side open and being provided with an end wall connected to a chassis of the road roller.  The chamber communicates with a vacuum source and is arranged so that, when vacuum is induced in the chamber, the pavement being compacted overlaps said open side of the chamber with the result that forces are transmitted from the chamber to the chassis of the road roller.  In one embodiment of the invention a plurality of chambers with carriages are mounted in an endless guide which is rigidly connected to the chassis.  Vacuum is induced during movement of the road roller in those chambers which are in contact with the pavement with the result that these chambers are sucked to the pavement surface.  Simultaneously carriages of all the chambers slide along the movable guide.

Abstract: ABSTRACT OF THE DISCLOSURE        Down-hole information from rotary well drilling opera-tions is transmitted to  a surface or remote location by the venting of drilling fluid from the interior of the drill stem into the bore-hole annulus in, for example, Binary Coded Decimal format.  A valve is caused to operate by the digital output of one or more down-hole transducers thus releasing and restoring the drilling fluid pressure in the desired sequence.          A "sub" contains the necessary electronics, power supply and a motorized valve assembly.  Commands from the surface to trans-mit information from any one of the transducers are transmitted by means of sequential pulses such as Binary Coded Decimal format, in the drilling fluid pressure which are provided by the operator by deliberately decreasing and then increasing the surface pump pressure in a sequence to which the applicable down-hole actuating means is responsive.

Abstract: ABSTRACT OF THE DISCLOSURE           Half-tone imaging is achieved in a flying spot scanning system wherein a highly collimated light beam is modulated with imaging information, reflected from a multi-faceted rotating polygon and directed to a scanned medium through a light attenuating member.  The latter member is supported proximate the imaging focal plane and orthogonal to the collimated, reflected light beam.  The light attenuat-ing member has an optical light transmission characteristic that varies in a continuous and cyclic pattern with a cycle period at least about ten times the maximum lateral extent of the collimated light beam, thereby serving to alter the system imaging from contrasting black and white patterns to half tones and gray colorations.

Abstract: PURIFICATION OF WASTE WATER HIGH IN CARBOHYDRATES AND SIMULTANEOUS PRODUCTION OF HIGH PROTEIN FEED PRODUCT     Abstract of the Disclosure A method for purifying waste water high in carbohydrate while obtaining therefrom a high-protein feed product.  The waste water is inoculated with yeast of the type that converts starch and sugars into more yeast.  The pH is adjusted to desired levels, and then the inoculated waste is circulated and recirculated in conjunction with air in amounts that enhance the growth rate of the yeast. The purified liquid waste is then separated from moist solids, and a large proportion of the moist solids is har-vested as feed material, while a smaller proportion is taken for use in recycle.  The proportion to be recycled is sent to a treatment zone where the pH is lowered to approximately 3.5 and where antibiotics are added, the lowering of the pH and the antibiotics both serving to suppress a substantial portion of bacterial growth while enabling the yeast to grow.  After a suitable dwell time, the treated material is used in the inoculating step as the inoculant.

Abstract: TITLE MINE ROOF SUPPORT FOR A MOBILE DRILLING MACHINE                     ABSTRACT OF THE DISCLOSURE           A horizontal deck extends forwardly from a self-propelled body portion.  An elevating mechanism pivotally connects the deck to the body portion for vertical movement of the deck into and out of position on the mine floor.  A mast-type roof drilling unit is mounted on the front of the deck and includes a vertically movable drill pot for advancing a rota-ting drill rod into the mine roof for drilling a bore hole therein.  The deck is positioned on the mine floor during the drilling operation.  During tramming of the body portion the deck is raised to an elevated position above the mine floor.          A roof support assembly is supported by telescoping devices above the deck to provide overhead protection for the machine operator during the drilling and tramming operations.  During drilling the roof support assembly is raised to abut the mine roof and support the mine roof above the operator on the deck.          To facilitate tramming the body portion, the deck is lowered from the mine roof a sufficient distance to permit raising the deck from the mine floor.
