Abstract: A polyurethane RIM method has two mixheads. Reactants are brought to each mixhead and are supplied as separate streams to two spaced cavities in a mold having a pre-formed porous mat separating the two cavities. One stream contains an isocyanate, polyol, chain extender and crosslinker selected to have a very low viscosity and which reacts to produce a high modulus armature or load bearing member. The other stream contains a polyol and isocyanate with additives that have relatively high viscosity to produce a semi-rigid polyurethane foam. At each mixhead the proportions of ingredients are controlled to give a desired isocyanate index to control the flex modulus and other properties of the loading bearing member and foam molded components of the product. The low viscosity material penetrates the porous mat to reinforce it and the porosity of the mat prevents the high viscosity material from entering the armature cavity so as to reduce the load capacity of the finished product.

Abstract: A hydraulic actuator with reduced interior volume includes a locking mechanism engageable with the main ram of the actuator to hold it in a fully retracted position without backlash. The locking mechanism comprises three locking jaws that move synchronously in a radial direction between lock or unlock position. Each of the jaws engage a groove cut into a rod adjacent the piston head of the main ram; the jaws are cammed into a locking position by a conical sleeve actuated by hydraulic pressure under the control of the main control valve. Jaw deactivation is accomplished by an opposed pressure which disengages the conical sleeve and the jaws are then spring biased into a cammed open position as the main ram begins to extend. Springs located between the individual jaw segments assist the camming action for opening the jaws.

Abstract: A container lifting arrangement wherein a pair of spaced rails and a vacuum cup assembly are concentrically mounted and relatively actuated to raise and lower a container, in part while the container is being conveyed toward a filling station by a conveyor. The vacuum cup is caused to engage the bottom surface of the container only after the container's forward movement has been stopped so as to not be subjected to any sliding action by the container, such action tending to roll the cup's edge and destroy its suction capabilities. Lifting the container before the conveyor stops provides additional time for filling the container.

Abstract: An elongated, preferably plastic handle has a sleeve lock on each of its opposite tip ends. When a twisted wire brush is placed in the handle and the sleeve is slipped over it, there is a guy wire effect from the sleeve which holds the brush firmly in place, as the sleeve stretches slightly over a bent end of the twisted wire of the brush. Each end of the inventive handle also has a tapered bore that may optionally hold the end of a wooden toothpick, which may be broken. The same sleeve which slips over the twisted wire stem of the brush, to anchor it in place, has a longitudinal cutout. The cutout is in the form of a cove opening into a funnel-shaped opening, with a nip between the cove and the funnel. The nip snaps over the toothpick to capture and hold it. The unbroken side of the sleeve which is opposite the cutout slips over the broken end of the toothbrush to help capture and cover it without leaving any exposed jagged fibers which could form splinters to damage mouth tissues.

Abstract: The invention relates to a support frame for a resistor element in a heating furnace for glass sheets, said flame providing a substantially continuously extending, elongated rest surface for a resistor element. The support frame elements consist of trough-like castings and are fastened to each other in an articulated manner. The short frame elements are easy to cast and can be assembled into long continuous support frames for resistor elements, the thermal stresses of said frames not passing over the link points. A long continuous support frame structure makes it accordingly possible to employ resistor elements that are long and continuous and thus readily replaceable.
