Abstract: An improved polyurethane RIM process using a polycarboxy-functional alkyl siloxane as an internal release agent characterized by:(1) Tool break-in or preconditioning with siloxane treatment of the surfaces;(2) Supplying the siloxane to the mix head as a third stream when necessary to prevent undesired side reactions;(3) Using a minimal amount of siloxane that is inadequate for mold release in the absence of the tool preconditioning;(4) Adjustment of catalyst package to counter the inhibiting effects of the siloxane.The use of a bare minimal amount of siloxane prevents excess siloxane from appearing in the surface of the article and causing subsequent paint wet-out and like difficulties. The third stream isolating of the siloxane prevents its carboxy-functional groups from reacting with the prepolymer or with other ingredients that may be carried in the polyol blend.

Abstract: An improved belt conveyor for conveying granular materials, such as grain. The conveyor comprises a pair of end sections which are connected together by a plurality of central sections to provide the conveyor with the desired length. An endless conveyor belt, having a plurality of integrally molded cleats, is carried by a pair of drive rollers, each of which is journalled in one of the end sections. The grain, or other granular material, is fed into a hopper at one of the end sections and is conveyed along the bottom surface of the conveyor sections by the cleats and is discharged through openings in the bottom surface to feed bins. The central conveyor sections are tapered throughout their length so that adjacent ends of the sections can be telescoped together to conveniently vary the length of the conveyor and facilitate attachment of the conveyor sections.

Abstract: An improved breather system for a sealed storage structure. An annular flexible diaphragm is located within the upper portion of the storage structure and the inner periphery of the diaphragm is sealed to a central inlet feed tube, while the outer periphery is sealed to an impervious platform that is mounted on the wall of the structure beneath the roof. A manhole is provided in the roof for entry onto the platform by workmen in order to repair or replace the diaphragm. The diaphragm and platform separate the storage structure into a lower storage chamber and an upper chamber which is exposed to the atmosphere. The diaphragm will move up and down within the structure in accordance with the pressure differential between the chambers. The diaphragm has a substantially greater surface area than the cross section area of the storage structure, so there is substantial travel between its uppermost and lowermost positions to thereby greatly increase the breathing capacity over conventional breather systems.

Abstract: This invention relates to a manually operated cutting tool for cutting notches or slits in metal, plastic and the like.

Abstract: A fluid power cylinder having a cylinder with an elongated slot extending generally parallel to the longitudinal axis of the cylinder, a reciprocally movable piston and a strip sealing means for successively sealing the slot during movement of the piston. The sealing member is of a laminated construction and is constructed partially of a magnetized rubber-like material for magnetic attraction to the cylinder wall adjacent the slot. The sealing member also includes beveled edges for engagement with beveled edges adjacent the slot.

Abstract: A metal cutting machine has a plurality of tool carrying cutting heads mounted for movement along a bridge which in turn is mounted on rails or the like for movement transverse to the direction of head movement. Controls are provided for selective movement of the heads and bridge. A bridge-mounted plurality of magnet assemblies are provided which, after one or more cut pieces have been formed from a plate-like workpiece by the heads, are actuated to engage the cut pieces and raise them from the remaining skeletal workpiece. The bridge on which the magnet assemblies are mounted is movable to a position remote from the workpiece so that the magnets can deposit the cut pieces at a receiving point. The assemblies may be mounted on the same bridge as the cutting heads and connected to the latter for selective horizontal positioning by the same controls used for cutting. Alternately, the assemblies may be mounted on a separate bridge disposed on the same rails.

Abstract: A universal joint comprising a block and pin type mount as component parts of honing tool assembly. Each pin is mounted and locked in place with set screws to the universal joint drive block.

Abstract: From a row of objects which are conveyed on an intermittently movable feeding conveyor, every second object is deposited on lines of wrapping materials at a first station, which lines are advanced continuously under the feeding conveyor, and the remaining objects are deposited on the same lines of wrapping materials at a following station. In connection with one or both depositing steps, the objects are shifted transversely of the direction in which said lines are advanced. Thus, the number of lines of wrapping material is only half the number of objects in each row, whereas the distance between the lines will be increased so much that the lines may be sealed lengthwise and crosswise by means of rotating sealing means.
