Abstract: The invention provides a separating vessel (10) suitable for use in the treatment of a mineral sample wherein a molten slag (11) is separated from a molten collector material (12) comprising a container defining an interior cavity (13) for receiving the molten materials (11, 12), an outlet aperture (14) leading from the interior cavity to the exterior of the container, and a separating surface (15) associated with the outlet aperture (14) which is shaped to cause droplets of flux (11a) to be carried along such surface, while droplets of collector material (12a) drip off such surface by the force of gravity.

Abstract: An elbow rotator apparatus for rotating an integrally formed section of an elbow workpiece includes a pair of gripping arms which are selectively positionable in a first position displaced from the elbow workpiece, and a second position in which the gripping arms are in contact with the integral section of the elbow workpiece. A rotary actuator is operatively connected to the gripping arms to selectively rotate the gripping arms by a predetermined amount when the gripping arms are in the second position.

Abstract: A semi-automatic gift or package wrapping method and apparatus is disclosed. The apparatus includes a machine frame that provides a work surface with measuring and wrapping sections. A sheet feed and cutting mechanism feeds paper from a role in two steps with a time pause in between for enabling a user or operator to partially wrap the package with part of the first section of dispensed paper web. Thereafter, the second section of paper web is dispensed and the web cut transversely at a trailing edge. Multiple selectable supply rolls are optionally provided, or a single roll machine can be used. Longitudinal cutters trim the sides of the paper to obtain a custom desired width for the full cut sheet. A user interface display controls machine functions such as start, continue and sheeter. In the sheeter mode, a selected number of sheets of a selected size can be dispensed and cut for use at another workstation to warp other boxes of known uniform size (i.e. shirt boxes at a department store).

Abstract: A construction panel for use with fiber reinforced concrete finish is disclosed. The panel includes a core member comprising a composite of wire trusses and foam blocks secured in a compressed shape. The core member also incorporates wire mesh strips having screed ridges for receiving and smoothing fiber reinforced concrete applied to the composite.

Abstract: An integral transverse flange for a duct includes a first upturned portion extending substantially perpendicularly from a duct wall of the duct. The flange further includes a second portion bent rearwardly from the first upturned portion, and a third return portion turned toward the duct wall and rounded back toward the first upturned portion from the second portion. A fourth L-shaped portion extends from the third return portion, the L-shaped portion having a first arm arranged adjacent to and in close relation with the second portion and a second arm arranged adjacent to and in close relation with the first upturned portion. A bead is formed in the first upturned portion.

Abstract: An insertion device configured for connecting to a frame of a concrete paving machine. The insertion device including a housing, a guide tube extending from the housing, and an ejection device positioned in the housing and cooperating with the guide tube to individually eject dowels stored by the housing through the guide tube. According to one embodiment, the housing includes an alignment system for aligning the dowels in the housing in a predetermined orientation. In another embodiment, the housing has a parting feature that extends along a forward external side of the housing. In yet another embodiment, the guide tube includes a resilient element provided at an outlet portion that is arranged to seal the outlet portion of the guide tube.

Abstract: A radiation detector of the present invention has at least one radiation measuring component and a radiation detector surface. A layer of protective covering substantially covers the radiation detector surface and protects the at least one radiation measuring component. The layer of protective covering preferably includes a protective material sub-layer and may include an optional coating sub-layer. The radiation detector surface may be, for example, a scintillator, cover glass, or chip surface.

Abstract: A pre-beading apparatus for fashioning a cylindrical includes a housing have a work surface and an aperture formed in the work surface, where the aperture is capable of accommodating the cylindrical workpiece. A rotatable head assembly is concentrically aligned with the aperture, and includes a bead wheel and a cut wheel disposed on opposing distal ends of the rotatable head assembly. A gripper assembly is disposed within the housing and includes a securing means that extends into the cylindrical workpiece and permits selective movement of the cylindrical workpiece in an axial direction.

Abstract: The invention provides a method of assaying a mineral sample for determining the concentration of selected metals in a sample comprising the steps of providing a comminuted mineral sample; mixing such sample with a flux; preheating a reaction vessel to a temperature which approximates the melting point of the flux; introducing the mixture of the mineral sample and flux into the crucible, whereby the mixture is transformed to a molten state to capture the metal to be assayed in a collector material; and separating slag from the collector material.

Abstract: A seam closing apparatus for use in sealing a duct seam having an outwardly extending sealing portion and a lower fold includes a handle portion having a power actuation trigger and a first roller for engaging the outwardly extending sealing portion of the duct seam. A second roller is also provided for engaging the lower fold of the duct seam. Operation of the power actuation trigger causes the first roller to rotate in a first direction, thereby flattening the outwardly extending sealing portion of the duct seam.
