Abstract: Dual oncoming air spoilers for vehicles are mounted near the hood to deflect air carried bugs, rain, road spray, snow, and lightweight debris up and away from the windshield. They are provided essentially in a one embodiment kit having: two plastic panels; two bottom channels to respectively receive the two panels; four bendable and breakaway pre-drilled and countersunk brackets to be used in securing the bottom channels and their inserted bottom edges of the dual oncoming air spoilers to a front of a vehicle on or near the hood and standard fastener assemblies, all these components being assembled and installed using conventional hand tools for drilling access holes to receive the fastener assemblies and to secure them. By following selective installation procedures, the contents of this one embodiment kit are mountable on many different vehicles having many different hood widths and hood contour designs.

Abstract: Apparatus for repairing portions of damaged material such as clothing fabric is described. A piece of mending cloth identical to the damaged material is placed over the damaged area of a fabric to be repaired, aligned and further placed upon a flat cutting die of metal having several different sized round holes therein. The proper hole is selected, the top edge about the parimeter acting as the cutting die. A cooperating punch assembly containing a cylindrical holder which can contain one metal sphere or two such spheres. If the punch assembly contains two such spheres, one may be swiveled or turned end for end so as to cut with the desired sphere. The spherical ball partically protrudes from the one end of a holder through a hole about which surrounds a shoulder area for cooperating with the die plate. The spherical ball is held loosely within the holder by retaining means opposite to the shoulder region.

Abstract: An electrical strain gauge is mounted to respond to movements between two sections of a structure. The gauge is mounted on a surface that deforms in response to mis-alignment of the sections in a selected plane. The mis-alignment or the deflection is detected electronically utilizing the strain gauge and the degree of deformation, mis-alignment, or flexure is monitored. Upon reaching selected magnitudes in either direction, signals are generated which may be used to control the amount of deflection. When utilized to control the alignment of sections of a traveling irrigation system, the strain gauge is attached to a bar between adjacent sections which bar flexes upon mis-alignment of sections in the horizontal plane. A pair of electrical sensors monitor the deflection but only one is permitted to generate a signal. A switching circuit selects the appropriate signal generator depending on the direction of travel of the equipment.
