    摘要： A display carton having an open front panel to display an article, and a central shelf panel parallel to and between the front and back panels of the carton. The carton has an article holding pocket formed by upper and lower transverse shelves hinged both to the shelf panel and to a front locking panel. The latter panel holds the transverse shelves in place by abutting the other end closure.

    摘要： DISCLOSED ARE A LIQUID HARDENER FOR CONVERTING A PHENOL ALDEHYDE RESIN INTO AN ADHESIVE, AND A METHOD OF ITS MANUFACTURE. USE OF THIS HARDENER AVOIDS PROBLEMS ASSOCIATED WITH THE USE OF KNOWN POWDERED HARDENERS, SUCH AS CAKING OR LUMPING UNDER HUMID CONDITIONS, AND THE LONG AND COMPLICATED MIXING PROCEDURE REQUIRED TO BLEND POWDERED HARDENER WITH LIQUID RESIN. THE LIQUID HARDENER IS PREPARED BY COMGINING WATER, ALCOHOL, FORMALDEHYDE SOLUTION, FILLER, PROTECTIVE COLLOID, PYROGENIC SILICA AND WETTING AGENT IN APPROPRIATE PROPORTIONS.

    摘要： A FOREST-DERIVED MATERIAL FOR USE AS A COAGULANT AND THE METHOD OF USE OF THE COAGULANT IS DESCRIBED. LIGNIN AND LIGNO-SULFONATE MATERIALS ARE REACTED WITH VARIOUS CHEMI CAL AGENTS TO INCREASE THEIR MOLECULAR WEIGHT FOR USE AS COAGULANTS. THE METHOD OF USING HIGH MOLECULAR WEIGHT, FOREST-DERIVED PHENOLIC POLYMERS AS COAGULANTS AND CLARIFYING AGENTS IN AQUEOUS SYSTEMS IS DESCRIBED. THE NOVEL COAGULANTS MAY BE USED IN CONJUNCTION WITH TRADITIONALLY USED COAGULANTS TO INCREASE THE RATE OF COAGULATION.

    摘要： The application discloses a moisture-content-measuring system utilizing shielded electrodes arranged in pairs on opposite sides of the material and wherein adjacent pairs of electrodes are energized in an out-of-phase relationship. Each electrode in each pair constitutes a portion of an individual bridge circuit with the arrangement being such that an output signal proportional to the moisture content of the material is derived from each electrode. The signals from each pair of electrodes are then combined and used in an overall system arrangement for determining moisture content. The effects of long cable runs and associated undesirable capacitance effects are avoided through the use of the system disclosed.

    摘要： AN APPLICATOR APPARATUS FOR PLACING A PRDETERMINED AMOUNT OF MATERIAL EVENLY OVER AN UNEVEN SURFACE. THE APPLICATOR ROLL HAS A COVERING OF RESILIENT MATERIAL. THIS MATERIAL HAS AN OUTER BARRIER SURFACE AND AN INITIAL SHORE DUROMETER OF 60 OR LESS ON THE 00 SCALE. PREFERABLY, IT IS BETWEEN 60 AND

    14 ON THE 00 SCALE. THE TRANSFER ROLLS ARE OF HARD MATERIAL. THE TRANSFER ROLL AND THE APPLICATOR ROLL BOTH ROTATE IN THE SAME DIRECTION CAUSING A SLIDING CONTACT BETWEEN THE ROLLS.

    摘要： A system for efficiently utilizing a wood veneer peeling lathe and dryer by installing a number of horizontally disposed and vertically spaced veneer storage and conveying trays spanning from the peeling lathe to the dryer. More levels of trays are provided than levels of conveyors in the dryer to insure a ready source of veneer to keep the dryer supplied with no gaps between pieces of veneer. A waste removal clipper may be positioned between the ends of the trays for removal of defective portions of veneer. The wetter portions of veneer can be conveyed to a slower dryer conveyor while the drier portions can be conveyed on a faster dryer conveyor without overdrying.

    摘要： A saw having a plurality of spaced teeth around the periphery of a saw disc and a plurality of slots cut inwardly of the periphery of the saw disc, the slots preferably being faced on the cutting side with a facing inlay extending substantially the length thereof, the facing inlay having a width substantially the same, or slightly less than the width of the kerf of the cutting teeth. The cutting edge of the slots is in a negative hook position with respect to saw motion and to a radial line extending from the center of the saw blade to the periphery thereof.
