Title: Pressure sensitive signal generator using  piezoelectric coating
Inventor: KOMPANEK HARRY W
IPC: H04R17/00
Filed: 1979-03-16
Granted: 1982-08-10
Abstract: ABSTRACT OF THE DISCLOSURE    The construction and method of operating a signal generator which provides an electrical output in response to an input mechanism such as a loading by finger are dis-closed.  The generator has the appearance of a plate and includes a sandwich structure comprising a conductive substrate, a coating of piezoelectric material and usually a plurality of discrete electrodes joined to the exposed surface thereof.  The coating is deposited on the substrate as a slurry and is chemically bonded to the substrate.  In order to produce an electrical output signal, prescribed locations on the plate are subjected to a force such as can be applied by the touch of a finger and a voltage is generated across the piezoelectric coating between the point of contact on the substrate and the adjacent electrode.  The output signal is used either directly or after being amplified to drive various functionally responsive devices.

Abstract: THREAD FORMING SCREW WITH STEP TAPER AND DIES FOR MAKING THE SAME     Abstract of the Disclosure A thread-forming screw has a point or lead thread portion having a relatively steep entry angle with respect to the screw axis.  Adjacent to the point thread is a tapered thread portion of about two to three pitches in axial length.  This tapered thread has a shallow entry angle defined by the taper of the maximum diameter of the thread toward the point.  This shallow entry angle may be approxi-mately 5° to 8° or equal to about three times the helix angle of the tapered thread.  This configuration of the tapered thread results in a balanced action of thread formation and axial in-feed of the screw, resulting in a lower end pressure to initiate the thread-forming in a workpiece.  A roll-threading die is contoured to provide ridges and valleys to effect the tapered thread portion.

Abstract: HARVESTER CUTTERHEAD KNIFE      SHARPENING DEVICE          Abstract of the Disclosure A forage harvester includes a rotary cylinder-type cutter-head mounted in a housing and having a plurality of knives with cutting edges that generate a cylinder as the cutterhead rotates.          A sharpening mechanism for the knives includes a pair of closed housings mounted on the opposite side walls of the cutterhead housing and a support member extending between said housings adjacent the cutterhead housing periphery, the opposite ends of the support member extending through openings in the housings and into the housing interiors.  The openings are substantially larger than the support member to permit adjustment of the sup-port member toward and away from the cutterhead periphery, and a pair of flexible seals are interposed between the ends of the support members and the respective housings to seal said openings. A manually rotatable crankshaft extends between the opposite housings and worm gearing connects the crankshaft to a threaded rod in each of the housings, each of said rods being threadable in one end of the support so that rotation of the crankshaft causes adjustment of the support member toward and away from the cutterhead.  A carrier is slidably mounted on the support member through a linear ball bearing and a sharpening stone is bonded to the carrier adjacent the cutterhead periphery, the carrier being reciprocatable back and forth along the support member by means of a handle extending through the cutterhead housing side wall, so that the stone can be reciprocated back and forth across the width of the cutterhead as it is brought into engagement with the cutterhead knives by rotating the crankshaft.  An interlock between the crankshaft and a door in the cutterhead housing prevents rotation of the crankshaft unless the housing door is closed.
