  • Patent number: 4373637
    Abstract: A collapsible corrugated fiberboard container to be fastened to a pallet. The container has a floor panel, two opposite side panels and two opposite end panels. The side panels and end panels are flexibly connected to each other, and the floor panel is connected to the bottom edges of the side panels. The floor panel is divided by score lines into a center portion and two outer portions which are on either side of the center portion. The center portion is attached to the pallet, and the outer portions are free to pivot about the score lines. The end panels are provided with vertical score lines. Bottom flaps are each connected to the bottom edge of the end panels and are also provided with score lines. The container can be collapsed due to the flexible connections between the side and end panels and the arrangement of the score lines so that the container can assume a flattened storage configuration above the pallet when not in use.

  • Patent number: 4318993
    Abstract: A two phase anaerobic digestion process in which an initial phase continually receives an organic feed for short detention times of less than two days under conditions which efficiently liquefy and breakdown the feed to lower molecular weight acids and other intermediates for conversion to methane. A succeeding phase is operated to treat the lower molecular weight acids and intermediates for detention times of about two to about seven days under conditions which efficiently lead to production to methane. The feed is loaded in the first phase at rates from about one to about ten pounds of total organics per cubic foot per day; and the products from the initial phase are loaded in the succeeding phase at rates of about 0.1 to about 0.5 pounds total organics per cubic foot per day.

  • Patent number: 4270036
    Abstract: A welding apparatus including, generally, a vertical clamping assembly having an upper and a lower clamping assembly for each of two rail sections to be welded together. These vertical clamping assemblies clamp and vertically align the running surfaces of the two rail sections, by establishing the running surfaces at a pre-determined stop level. The welding apparatus also includes a horizontal centering and aligning apparatus which has a first pair of clamping arms which engage the rail base and pre-center the rail sections with respect to one another and to the welding apparatus. The apparatus also includes a pair of spaced apart clamping arms associated with each of the rail sections which are operable to both laterally clamp the rail heads of the respective rail sections and to horizontally or laterally align the rail sections with respect to one another. Once aligned, the ends of the rail sections are welded together.

  • Patent number: 4267703
    Abstract: A feed stock comprising sugar, milk solids, a significant amount of moisture, and in some instances chocolate, is raised to a temperature of about C. and at the same time is condensed to have a moisture content of between about 4% and 6%. This is done by moving the material upwardly in an annular column and heating the walls defining that annular column. The condensed material is maintained at its final temperature and transferred to a crystallizer. In the crystallizer it is moved downwardly and kneaded. The kneading is performed by two sets of interdigitating rods, one set being stationary and the other set moving transversely to the downward path of movement of the material. As it is being kneaded it is cooled, both by contact with refrigerated surfaces and also by a countercurrent flow of cool air. The kneading is continued until the product is crystallized and particulate. Thereafter, it is optionally dried to a moisture content of about 1%.

  • Patent number: 4267781
    Abstract: A pallet post which comprises a truncated, cone-shaped outer body and a cylindrical-shaped inner body encompassed by the outer body and attached thereto by a plurality of spaced-apart flanges. The post has a top wall on the larger end of the cone-shaped outer body, and the inner body has a portion extending beyond the outer body at at least the end thereof having the top wall. The inner body also has an axial bore extending through it. The post is secured to a pallet by extending the shaft portion of a rivet having an enlarged head through a hole in the pallet into the axial bore in the inner body of the post. The extend portion or portions of the inner body of the post are disposed within the holes in the pallet to provide additional support.

  • Patent number: 4208387
    Abstract: Sulfur dioxide is removed from waste gases such as stack gases by contacting the gas stream with free tertiary amines having basic strengths greater than about pK 5 to form a coordinate covalent complex of the amine and the sulfur dioxide. The sufficiently stable complex is than thermally regenerated to liberate the sulfur dioxide in one stream, to provide the residual gases in another stream, and to provide the regenerated tertiary amine for collection and reuse in a subsequent sulfur dioxide cleanup step. The coordinate covalent complex reacts with even very small concentrations of sulfur dioxide to effectively reduce the sulfur dioxide to detectable zero levels. The presence of carbon dioxide in waste gas streams does not interfere with the efficient cleanup because the selected tertiary amine does not react with the carbon dioxide.

  • Patent number: 4190960
    Abstract: A navigational plotter which generally comprises a rectangular elongated member comprising two straight edges and having a circular protractor rotatably secured thereto in the geometric center. The rectangular elongated member has a plurality of distance scales formed along and adjacent to each of the two opposite longitudinal straight edges thereof. These distance scales correspond to, for example, statute miles, nautical miles or kilometers, and each scale is spaced apart from the other to provide between adjacent scales a clear, unobstructed course line window which permits the navigational plotter to be placed over or adjacent to a course line on a chart without obscuring it. The scales along one longitudinal straight edge of the navigational plotter can correspond to the scaling of, for example, sectional charts, while those along the opposite longitudinal straight edge can correspond to, for example, the scaling of the WAC charts.

  • Patent number: 4174793
    Abstract: A storage receptacle is formed by a length of material having opposed terminal ends and a substantially centrally positioned fold line, the length of material being foldable along the central fold line to create two substantially equal sections, each of the sections including one or more storage compartments formed therein. Each of the storage compartments is ideally provided with a closure flap, and fastening elements are interposed between the closure flap and the storage compartment thereby to permit the sealing of each of the storage compartments. Finally, other fastening elements are further provided in connection with the terminal ends of the length of material to permit the sections to be folded over and fastened together such that the entire receptacle may be stored about a support such as a belt.

  • Patent number: 4171017
    Abstract: In accordance with the method of the present invention, methane and other similar fuel components are separated from the brine found in geopressurized geothermal zones by immersing gas permeable membranes selective for these fuel components into the brine in these zones, and permitting these fuel components to permeate through the membranes while rejecting the brine. The permeated fuel components then are collected.
