Abstract: A device for metering and transferring liquid non-ferrous metals. A hollow sleeve is mounted on a supporting structure and a pouring spout is on one end of the hollow sleeve. An orifice is in the pouring spout communicating with the interior of the sleeve. A stopper rod extends into the sleeve and is shiftable between a position seating on the pouring spout and sealing the orifice therein and a position removed from the pouring spout to permit liquid metal to flow into and out of the hollow sleeve. The parts are made of cast iron and the stopper rod has a tungsten carbide tip for passage through the orifice during the sealing and unsealing thereof to clean the orifice and to prevent foreign matter from collecting in the orifice.

Abstract: A method of making a module for use in processes such as reverse osmosis, ultrafiltration, dialysis, and the like in which hollow filaments to be utilized as semi-permeable membranes comprise a coreless annular array of helically wound filaments.

Abstract: An improved method of making syntatic modules which includes the following steps. A preform mold and a casting mold are formed of predetermined configuration. A woven roving of predetermined size is formed to provide a skin. Additionally a layer of spacer material is formed which includes a plurality of voids. The roving is attached to the spacer material to form a laminate. The laminate is formed to the insidewalls of the preform mold and then the preform mold is filled with a plurality of hollow balls. A thin layer of resin is poured into the preform mold to connect the balls. The composite is removed from the preform mold and placed into the casting mold after spacer material is attached to the exposed end portions of the composite. A syntatic foam resin is added to the casting mold interior so as to fill all spaces between the balls and all voids in the spacer material. The syntatic foam resin is then cured and the mold parts are removed thereby producing a module.

Abstract: A device for controlling the release of vapors such as insect attractants, insecticides, and other vapors such as flower fragrances (the release being a timed matter in accordance with a predetermined configuration of the device), consisting of a microdispenser for accurately controlled dissemination of vaporizable materials comprising an elongated conduit of regulated cross-sectional area and length, and a vaporizable substance enclosed in said conduit. The filamentary conduit has one open and one closed end. In another variant, a filamentary conduit can be sealed between two open ends to provide a pair of end-to-end closed end conduits. The vapor producing substance is placed in the capillary conduit by suitable means. A single filamentary tube may be used, or a plurality of such tubes together. Liquid is contained within the conduit against the action of gravity and vibrations.

Abstract: A novel open weave endless dryer belt is disclosed which comprises in a leno weave, warp yarns of synthetic organic fibers and crosswise yarns of synthetic organic fibers braided over a core of glass fibers and/or metal wire. The fabric weave is then finished with a coating of a temperature resistant resin. The fabric of the invention is useful for fabricating conveyor belts employed in conveying textiles through dryers and in like applications.

Abstract: A suction box cover for a Fourdrinier papermaking machine includes a leading portion having a top surface which supports a travelling Fourdinier fabric. The leading portion has a channel across its length which includes a lower manifold region and an upwardly projecting throat region that opens upon the fabric supporting surface. A lubricating fluid is fed to the manifold region and flows upwardly through a series of orifices in a metering member retained within the channel to the fabric supporting surface to lubricate the fabric.

Abstract: A fabric connector seam in which woven complementary seam-halves joined by a pintle are provided and in which each seam-half comprises a single and a double layer zone mechanically bound by the nature of the weave and in which the crosswise yarns of each seam-half form alternately displaced loops on one edge thereof which can be intermeshed with like loops formed on the edge of the remaining seam-half.

Abstract: Apparatus is disclosed which is useful for severing a continuous length of yarn or monofilament containing knots or slubs, to prevent their takeup into yarn or monofilament processing machinery. The apparatus is advantageous in that it is of simple construction, reliable in operation and positively prevents damage to down-stream processing equipment.

Abstract: An improved method of making syntatic modules is provided. The method includes the steps of forming a mold and adhering an expanded honeycomb material to the interior surface of the mold. The mold is then closed at one end and filled with hollow, plastic spheres from the other end. After the spheres are in place, a syntatic foam is pumped into the mold from the bottom, filling all spaces between the balls with the foam. The foam is then permitted to set after which the mold is removed, leaving the desired module. Thereafter, a skin may be applied to the module.

Abstract: A method and apparatus are provided for evenly disseminating by broadcast techniques trace quantities of biologically active chemicals such as nutrients, insecticides, fungicides, growth regulators and the like. The biologically active chemical is encapsulated in a microdispenser such as a filamentary conduit of regulated cross-section and length. The filled microdispensers are then metered into a moving carrier fluid stream, preferably air, and the carrier fluid containing the microdispensers is then evenly dispensed throughout the area. In an alternate preferred embodiment, the microdispensers are coated with a second material which may be either another biologically active material or a sticker for attaching the microdispenser to living organisms such as plants or animals. The method and apparatus is also applicable to biologically active chemicals contained in laminated microdispenser structures for dissemination and release.

Abstract: A shower for use in fabric conditioning in paper making utilizing a two position nozzle. One position being a spray position and in which the nozzle is maintained in this position by normal liquid pressure in the spray pipe and a second position which is a purging position and in which the nozzle is maintained in this position by application of air pressure.

Abstract: A bearing lubrication system for a bowed roll of the type having a series of spools disposed for rotation about a shaft is provided. Each of the spools is supported on the outer race of a bearing, the inner race of which is secured to the shaft. The system includes a lubricant reservoir and a plurality of lines extending from the reservoir along the shaft to fittings mounted on the side walls of the bearings.

Abstract: An improved billiard ball is provided comprising a major portion and a minor portion together forming a solid, spherical body. The minor portion is preformed with inclined surfaces which define an interlock adapted to cooperate with associated surfaces of the major portion to form a mechanical bond between the major and minor portions after the major portion is formed about the minor portion. When the minor portion is molded in the shape of a bracelet, a slit may be provided therein to relieve stresses caused by shrinkage during cooling.
