Abstract: A system for re-assembling collapsed collapsible topless containers which have four side walls pivotal to each other and a pallet. The system unfolds a collapsed container by lifting it up by one of the sides. The unfolded container is transferred to an assembling sub-unit which tips the unfolded container upright and deposits it on the pallet which releasably engages two opposing side walls.

Abstract: A lower receptacle includes sidewalls having an upper edge. The receptacle is adapted to contain a quantity of fluid. A sleeve holds the lower receptacle. An upper lid has a conical upper surface and a plurality of vertical access ports. An access ramp leads crawling insects gradually upward to the ports. A rain shield forms an apex of the upper lid. The upper lid is removably affixable to the lower receptacle at the upper edge of the sidewalls.

Abstract: Pigmented ink formulations of different colors, for use in ink jet printers, are optimized with respect to print quality, by the choice of pigments, by controlling the physical characteristics of each pigment dispersion, and by following a particular sequence of manufacturing steps. Controlling surface tension renders the inks compatible with one another; controlling particle size distribution provides flowability; and pigment selection provides resistance to fading.

Abstract: In a power-and-free conveyor system an anti-backup devise for attachment at a work station comprising a block, and a stop and a cam mounted on the block and a spring for applying force to the cam to frictionally engage a wheel of a trolley on the power-and-tree system.

Abstract: A guide apparatus for cutting roofing shingles includes a rigid base plate, substantially rectangular in shape, having a first end wall spaced from a second end wall; a first side wall spaced from a second side wall; a cutting guide pivotally supported on the base plate along the first side wall; and upright guide surfaces mounted for sliding movement on the base plate adjacent to the second side wall. The cutting guide may be fixed at non-perpendicular and perpendicular angles to the long axis of the base plate. A scale having reference markings for cutting shingles at predetermined lengths is mounted along the first side wall. The scale may be utilized to determine points at which the beginning and the end of a cut can occur both easily and accurately. A modification of the invention includes an outward extension of the base plate along the first side wall, the extension having an opening within it, the combination serving as a carrying handle for the guide apparatus.
