Abstract: A sheet workpiece having an edge bent over on one face of the workpiece towards the center of the workpiece is continuously displaced in a transport direction over a flat support surface that lies against the other face of the workpiece at the bent-over edge. Compressed air is blown from a guide in a flow direction extending transverse to the transport direction, outwardly from the workpiece center, and generally parallel to the surface so as to blow this bent-over edge flat. A plurality of nozzles inclined slightly downwardly toward the surface and backwardly in the transport direction may be employed, as a single elongated nozzle producing a band-shaped current of air may be used, or a plurality of nozzles spread out in a two-dimensional array. Such a flow of air may also be directed from both faces at the workpiece edge in order to flatten out this edge no matter which way it is bent over.

Abstract: Lithographic offset alignment techniques for MOS dynamic RAM memory cell fabrication to enable increased packing density while maintaining the minimum patterned geometry. Technique of cell fabrication involves initial oxidation of P-type silicon, for example, followed by silicon nitride deposition. Thereafter, moats are etched using the composite silicon dioxide-silicon nitride layers, followed by boron deposition or ion implantation in regions of the silicon substrate exposed by the etching treatment. The moats are then filled by oxidation to form a large field deposit of silicon dioxide extending above the level of the oxide layer in the regions where the moats were formed. The remaining composite silicon dioxide-silicon nitride layers are then removed, followed by gate oxidation. A P-type ion implant is provided beneath the thin oxide region between the regions to be overlaid by a polysilicon electrode and the thick field oxide of the succeeding cell.

Abstract: A moisture remover for produce is preferably installed in an enclosure within which a produce support such as a foraminous conveyor is installed. A fan takes heated air from a heater and discharges the heated air upwardly through the conveyor and then through the produce itself. Air leaving the produce returns to the air heater for reheating and recirculation by the fan. Moisture from the produce rises and travels to a cooler within the enclosure and condenses on the cooler. There is no air circulation through the cooler. Moisture condensed on the cooler is drained from the cooler and preferably is discharged outside the enclosure and is not reevaporated into the recirculating heated air.

Abstract: A lighter than air toy consisting of a basket gondola made of a light plastic or other material attached to the bottom of a toy balloon filled with a gas less dense than air, such as helium. The balloon, when inflated with a gas less dense than air, provides the buoyancy to lift the gondola into the air and allows it to rise freely or float at a predetermined level. Ballast weights can be added to the gondola to balance the buoyancy force so that the force of gravitation on the gondola and balloon is exactly balanced by the buoyant force whereby the gondola and balloon assembly together have a neutral buoyancy in the air. The basket gondola and balloon are held together by means of stretching the knot of the balloon through a keyhole slot made in the basket gondola. The knot is held in place by wedging it into the thin part of the keyhole slot. This invention is simple to make and put together. The basket gondola can be used as a childs toy or for advertising promotion.

Abstract: A generally U-shaped clip of spring steel is adapted for holding plants in a predetermined position along a brick wall or the like. The clip comprises generally flat legs extending outwardly from a bend at a relatively wide angle when the clip is in its untensioned state. The free ends of the legs are separated by a greater distance in such untensioned state than the distance between adjacent bricks at a mortar joint of the brick wall. By forcing the legs together, the clip can be installed in the crevice at the mortar joint with the free ends of the legs engaging the opposed surfaces of adjacent bricks. The spring tension retained by the clip when installed in the crevice secures the clip to the wall by frictional engagement with the surfaces of the adjacent bricks. A suitable retainer, such as a twist of wire attached to the bend of the clip, permits vines or the like to be fastened in place against the wall.

The gate sections are respectively mounted by inclined hinges on a pair of spaced supporting members whereby the gate sections are automatically drawn under the influence of gravity back to their closed positions after the vehicle has passed therethrough whereupon the latching mechanisms automatically relatch the gate sections in their closed positions.

Abstract: A cup-shaped support member for a lift-cylinder in a horizontal door structure, such as a hatchway, in which the lift-cylinder counter-balances the weight of the door. The base of the lift-cylinder is pressed against the bottom of the cup by its spring in the usual manner, and tilts about a flange on the foot as the door is swung open or closed. One or more clean-out holes are provided in the cup bottom, and an inturned lip is formed on the edge of the cup so that it overlaps the flange on the foot of the lift-cylinder. Foreign matter, such as dirt or ice, which heretofore has built-up under the foot of the lift-cylinder until the foot of the cylinder is lifted out of the cup, is forced through the clean-out holes in the support cup by engagement of the lip with the flange on the cylinder foot, preventing it from being lifted off the bottom of the cup while still allowing the cylinder to tilt freely.
