  • Apparatus and method for orienting and stacking generally planar workpieces
    Patent number: 6468024
    Abstract: Disclosed are machines and methods of orienting and stacking a stream of workpieces when it is desirable to stack at lease some of the workpieces in a face-to-face or back-to-back orientation. The apparatus has a receiving assembly for receiving a continuous stream of workpieces. A flipping assembly follows the receiving assembly for selectively flipping selected workpieces onto their opposing faces. Downstream from the flipping assembly, a stacking guide is positioned for guiding the workpieces into stacks for further manual or automated handling.
    Type: Grant

  • Ventilator having insert for controlling moisture and method of making same
    Patent number: 4512243
    Abstract: A ventilator device for allowing escape of air from enclosed spaces such as a building includes a unitary housing provided with an insert for controlling the flow of mositure therethrough. The insulator includes a pair of insulative, tubular members between which there is sandwiched a fabric-like foraminous membrane which permits passage of moisture laden air outwardly through the ventilator but prevents moisture in the form of liquid or droplets from returning into the building through the ventilator.

  • Methods of constructing a one-piece roof vent device
    Patent number: 4370876
    Abstract: A unitary metal vent apparatus for securement to the roof of a building is formed from a single aluminum disk, into the form of a first flange portion, a tubular second portion, a cap-shaped third portion, and a vent hole portion disposed between the tubular portion and the cap portion. Preferably, the apparatus is produced by spinning a tubular protrusion in an aluminum disk, drilling vent holes, and collapsing the end of the tubular protrusion to form a cap-shaped portion.
