Abstract: A first mixer trailer forms the plant frame foundation around a twelve-yard compulsory mixer. The compulsory mixer is mounted for elevation relative to plant frame foundation by hydraulic lifting columns. In system erection, a cement silo trailer is first mounted to the top of the compulsory mixer when the compulsory mixer is at ground level. Thereafter, both the mounted silo and the compulsory mixer are raised and pinned in place by the hydraulic lifting columns so that gravitational discharge of mixed concrete can occur directly from the compulsory mixer to an underlying transporting apparatus, usually a truck.

Abstract: In the process of die-cutting bag stacks to form individual bag tops, die-cut handle apertures, or other mounting apertures, die blade configurations forming the vent lines of an array of vent apertures are also used to bond the outer surfaces of the front and rear bag walls together. The die-cutting operation selectively bonds the successive front and rear bag walls together at or adjacent the cut edges of the vent lines, thereby allowing the bags in a bag stack to subsequently self-open when dispensed.

In a manufacture of the compound material two matrix components can be liquefied and fiber filaments of the fiber component can be wetted by the liquefied matrix components. In this in the liquefied state the one matrix component is not soluble in the other. In a consolidation of the compound material one of the previously liquefied matrix components can be hardened out irreversibly to a duroplastic whereas the other of the previously liquefied matrix components remains meltable.

Abstract: A twin shaft “compulsory mixer” having a capacity in the range of twelve cubic yards has a static mixing chamber bottom defined from two horizontally disposed and interfering cylindrical shapes. Two centrally disposed elongate rectilinear discharge gates are each defined from an end in the bottom of the static mixing chamber to abut at the middle of the static mixing chamber. At the middle bottom of the static mixing chamber, a tensioning rod is placed extending normally across the abutted ends of the two rectilinear slots. Two eccentrically mounted elongate rectilinear gates are mounted for movement into and out of sealing relation to the rectilinear slot centrally of the static mixing chamber. These gates are mounted centrally of the mixing chamber to a block and spherical bearing arrangement and actuated at the respective static mixer chamber ends by conventional piston drives. Reducing the gates in length, reduces deflection making chamber sealing possible.

Abstract: A thermal processing chamber configured to enclose and heat treat a single electronic substrate at an exposed surface, such as a wafer or electronic circuit board being re-melted, includes an enclosed gas tight and particle free heat insulated chamber. An electronic substrate support is placed within the enclosed gas tight and particle free heat insulated chamber. A convection gas inlet distribution manifold adjustable in spatial relation towards and away from the surface to be treated provides a flow of heated gas over and onto the exposed surface of the electronic substrate to be treated. A heated convection gas outlet is placed below the electronic substrate for the collection of heated gas after flowing over, around and below the exposed surface of the electronic substrate to be treated. A door is movable between and open and closed position. The door opens a path to move the electronic substrate into and out of the chamber to and from the electronic substrate support in an open position.

Abstract: A three-message sign having internal light source has an array of side-by-side triangular sign elements. Each of the triangular sign elements has three transparent display surfaces with three apices joining the three transparent display surfaces into the triangular sign element. The transparent display surfaces permit the array to display a discrete message when the array of triangular sign elements is simultaneously rotated to present the display surfaces for a single message. Each of the side-by-side triangular sign elements has a internal light source extending from at least one end of the triangular sign element across the transparent display surfaces of the triangular sign element. Transparent and opposed U-shaped holders are placed along edges of the transparent display surfaces, each transparent and opposed U-shaped element defining an indentation for trapping the edges of translucent message display strips.

Abstract: A bringer gripper for looms without shuttles, where the weft yam is placed in an upper notch and in a gripping organ, particularly suitable for the simultaneous presentation of one or more wefts to the warp inlet and to the taker gripper, in which the upper notch is shaped with a multiple number of throats of different axial length. The weft yarns fit into the bottom of these throats and are essentially offset in the gripper's direction of motion.

Abstract: Laser capture microdissection occurs where the transfer polymer film is placed on a substrate overlying visualized and selected cellular material from a sample for extraction. The transfer polymer film is focally activated (melted) with a pulse brief enough to allow the melted volume to be confined to that polymer directly irradiated. This invention uses brief pulses to reduce the thermal diffusion into surrounding non-irradiated polymer, preventing it from being heated hot enough to melt while providing sufficient heat by direct absorption in the small focal volume directly irradiated by the focused laser beam. This method can be used both in previously disclosed contact LCM, non contact LCM, using either condenser-side (or beam passes through polymer before tissue) or epi-irradiation (or laser passes through tissue before polymer). It can be used in configuration in which laser passes through tissue before polymer with and without an additional rigid substrate.

Abstract: A plurality of glass or metal wires are precisely etched to form the desired shape of the individual channels of the final polycapillary optic. This shape is created by carefully controlling the withdrawal speed of a group of wires from an etchant bath. The etched wires undergo a subsequent operation to create an extremely smooth surface. This surface is coated with a layer of material which is selected to maximize the reflectivity of the radiation being used. This reflective surface may be a single layer of material, or a multilayer coating for optimizing the reflectivity in a narrower wavelength interval. The collection of individual wires is assembled into a close-packed multi-wire bundle, and the wires are bonded together in a manner which preserves the close-pack configuration, irrespective of the local wire diameter. The initial wires are then removed by either a chemical etching procedure or mechanical force.
