  • Publication number: 20050241978
    Abstract: A shipping container or package for temperature-sensitive products that can ship in a collapsed or flat configuration made up of an unassembled corrugated container or box, laid flat to which is secured a rectangular sheet of semi-rigid or flexible foam that has had three (3) parallel grooves and both ends mitered into it so that the insulating sheet can be folded as the container or box is assembled, yet shipped flat.

  • Patent number: 5960711
    Abstract: The invention relates to a conical screw press for compressing and for removing liquid from bulk material, comprising a screw with a screw thread and a core in a housing, structure for rotating the screw in the housing, an inlet opening for the bulk material from which liquid is to be removed, an outlet opening for the bulk material from which liquid has been removed, and at least one outlet opening for the liquid which has been extracted. The characteristic features of the invention are that: a) the screw is dimensioned, for at least the greater portion of the length of the screw between the inlet opening for bulk material and the outlet opening for bulk material, such that the external diameter (D) of the screw thread and the diameter (d) of the screw core change axially in the screw press from a first axial position, where the external diameter of the screw thread=D.sub.1 and the diameter of the screw core=d.sub.

  • Patent number: 5605184
    Abstract: The invention relates to an apparatus for debarking logs individually with the aid of high-pressure water jets. The spray nozzles are intended to spray water in focused jets against the log at the same time as the log moves past the spray nozzles. The invention is characterized by a ring (22) through which the log is intended to be fed, in that units (42, 46, 46') are mounted on the inside of the ring, uniformly distributed about the periphery of the said ring, which units are intended to bear against the surface of the log passing through the ring, in that a spray nozzle (40) is arranged in each such unit, which spray nozzle is made to maintain an essentially constant distance from the surface of the log by means of the fact that the unit bears against the surface of the log, this distance lying within a range of distance from the surface of the log which is optimal for debarking.

  • Patent number: 4774831
    Abstract: The present invention relates to a method and a device for determining the moisture content in a moist material in the form of particles or pieces, such as sand, gravel, dry mortar, coal, chips, and the like. In accordance with the invention, partly the cooling effect of the material on a measuring body (1, 35, 41, 50), performing in the material, at a temperature above the boiling point of the liquid, is recorded, the material and the measuring body moving in relation to each other, and partly the cooling effect of the material on a measuring body (2), performing in the material, at a temperature below the boiling point of the liquid, is recorded. The comparison between the two recordings results in a relation, which gives a measure as to the moisture content.
