Abstract: WASTE TREATMENT SYSTEM HAVING INTEGRAL INTRACHANNEL CLARIFIER              ABSTRACT OF THE DISCLOSURE An intrachannel clarifier for producing clarified waste liquid within an oxidation clitch aerobic wastewater treatment system.  The clarifier comprises a tank-like con-struction positioned in the upper portion of the oxidation ditch channel and having an opening in an upstream wall for admitting mixed liquor at a relatively slow rate.  The region within the clarifier establishes a quiescent zone where solids may settle from the waste liquid by gravity to the tank bottom.  A portion of the clarified liquid is removed by means of an overflow weir or launder.  The bottom of the clarifier forms a perforated baffle made up of a plurality of spaced parallel slightly overlapping inverted V-shaped angle members extending between the walls of the oxidation ditch channel.  The spaces between the angle members permit  settled solids to return to the mixed liquor flowing beneath the clarifier, but prevent  movement of excessive quantities of mixed liquor into the quiescent zone. In a first embodiment, the clarifier is constructed as an integral part of the oxidation ditch.  In a second embodi-ment, the clarifier is constructed as a separate unit which may be added to an existing oxidation ditch to provide retro-fit intrachannel clarifier capability.

Abstract: ABSTRACT OF THE DISCLOSURE      A raised decorative pattern is formed on a fabric by cutting spaced-apart slits side-by-side in a row in the fabric thereby to form in sequence first, second, third, and further strips as required of the fabric between adjacent slits and successively knitting the strips by a process resembling crocheting which comprises passing the second strip as a partial loop under and around the first strip, passing the third strip as a partial loop under and around the partial loop of the second strip, and thus successively repeating the proce-dure with the successive strips.  A fabric with such a pattern can find use in a broad range of articles.

Abstract: ABSTRACT A system for heating or cooling articles conveyed in a vertical helical path is defined by an endless conveyor belt driven at its inner edge by contact with a rotating drum and a circulating heat exchange fluid propelled horizontally onto the articles by axial flow fans rotating in a vertical plane. The system features a novel arrangement employing scroll means for confining the circulating heat exchange fluid to a substantial portion of the helical path and location of fan means such that the heat exchange fluid is propelled in push-pull manner from the discharge side of one fan means to the intake or suction side of a second fan means. In the preferred embodiment directed to refrigeration of conveyed articles, more particularly foodstuffs to be frozen, the conveyor is located within an insulating housing. Further featured novelty includes location of the driving means for the rotating drum externally of the housing and directing of refrigerant, such as liquid CO2 into the fan blast in a direction counter to that of the blast.

Abstract: Abstract of the Invention A method and apparatus for improving the efficiency of a heat generator in which combustible fuels such as fossil fuels, refuse, or other materials are burned is described. Flue gas generated in the heat generator and combustion air are passed in heat exchange relationship in a heat exchanger. The heat exchanger is selected so that it removes a substantial amount of heat from the flue gas, whose temperature is conse-quently lowered to a level where a corrosive pollutant is likely to condense out. A pollutant removing liquid is applied onto the portion of the heat exchanger where the flue gas passes through both to scrub the flue gas and protect that portion of the heat exchanger from corrosive effects from condensed pollutants.  Particulates and gaseous pollutants are removed from the flue gas and the heat exchanger by the liquid, which may be a neutralizing liquid such as an alkaline solution to provide a protective sheath for the heat exchanger against the effects of corrosive pollutants.  In the described illustrative embodiment, the invention is shown in use with a thermal section for a large scale power plant.

Additional line is extended from a supply line coil (?9) within the head into the cutting plane without independent operator action. A mechanism in the head automatically feeds replacement line whenever the free end of the cutting line is reduced to less than a predetermined maximum length in the cutting plane. The cutting line length is always extended to this predetermined maximum length at all operational rotational speeds, without adjustment, and in a positive step-by step made of segmental line advancement. The line feeder mechanism, has an escapement cam (56) with an off center pivotal mounting (46) that senses both centrifugal forces on the cutting line and changes in rotary speed of the head.

Abstract: ABSTRACT OF THE DISCLOSURE DOCUMENT FEEDER WITH IMPROVED VACUUM SYSTEM  A document feeder defines a sheet path along which a document sheet is fed across a platen of a copier/duplicator, for example, in order to copy the sheet.  An oscillating vacuum tube feeds sheets from a supply into the sheet path.  The feeder includes a platen vacuum transport having vacuum belts that move the sheet cross the platen.  The vacuum transport has a first vacuum plenum and a second vacuum plenum located along the sheet path.  The first vacuum plenum has a relatively high level of vacuum to insure lifting of the sheet onto the vacuum belts.  The sheet is then transported into the area where it comes under the influence of the second vacuum plenum.  The second vacuum plenum has a somewhat lower level of vacuum, but it is sufficient to retain the sheet on the belts as the belts drive the sheet into engagement with a registration member.  The lower level of vacuum applied at the time the sheet engages the registration member avoids damage to the leading edge of the sheet. The lower level of vacuum in the second plenum also allows the belts to be continuously driven after the sheet reaches the registration member to correct any mis-alignment of the sheet.

Abstract: LOG PROCESSING APPARATUS             Abstract of the Disclosure A method and apparatus of processing logs prior to further processing in lumber, plywood, pulp or veneer mills. In the apparatus, logs are deposited into a cradle formed between a rotating cutter drum and support rollers which guide the log against the cutting drum and rotate the log about its longitudinal axis in a direction opposite to the rotation of the cutter drum, at a controlled speed slower than the drum. Constant rotation of the log reduces horsepower requirements by minimizing the length of each cut made by cutter assemblies extending from the cutter drum.          Logs are discharged by lowering the guide rollers with respect to the cutter drum.  A second embodiment is disclosed including a pair of cooperating rollers providing a variable sized cradle adjacent to the cutter drum.   Means for delivering logs to the apparatus and for removing material cut from the log are disclosed. In a single operation, logs are debarked, rounded, reduced to any desired diameter, or completely reduced to chips.

Abstract: Process For Fabricating Ribbed Electrode Substrates And Other Articles Abstract A process for fabricating a resin bonded carbon fiber article, and in particular electrochemical cell electrode substrates and the like requiring different mean pore sizes in different areas, involves simultaneously heating and compacting different mixtures of carbon fibers and resin in different areas of an article forming mold, wherein the carbon fibers in each of the different mixtures have different, known bulk densities.  The different bulk densities of the carbon fibers in the mixtures are chosen to yield the desired mean pore sizes and other properties in the article after heating and compacting the mixtures,  Preferably, the different bulk densities are obtained using different carbon fiber lengths in the molding mixtures.  The process is well suited to forming ribbed electrode substrates with preselected optimum  mean pore sizes, porosities, and densities in the ribs, the webs connecting the ribs, and in the edge seals.
