Title: Self-preparing electrode with removable plastic abrading brush and method and apparatus for assembling same
Inventor: SHERWIN GARY W
IPC: A46D3/04
Filed: 1989-12-06
Abstract: W.E. 54,664 ABSTRACT OF THE DISCLOSURE      A  self-preparing  electrode  includes  a  conductive conical disk and a nonconductive plastic abrading brush removably interfitted through an aperture in the disk. The brush extends axially through the disk cavity to an abrading end of the brush disposed beyond the cavity at the large diameter end of the disk.   The brush also extends axially through and beyond the aperture of the disk to a fused end of the brush which holds the strands or bristles of the brush together.   An apparatus which fabricates the brush and assembles it to an electrode disk uses a pair of pressure roller to feed multiple strands  from supply spools mounted in a supply rack, through input and output tubular orifices, to and through the aperture of the disk.  A shuttle positions a fusing anvil in contact with the leading ends of the strands extending through the disk aperture for fusing them into a connecting bead.   A cutting blade is then employed to sever the strands a short distance  from the disk to finish  forming  the brush  and define  an abrading end thereon.

Title: Electronic article surveillance system with improved differentiation
Inventor: LIZZI PHILLIP J
IPC: G01V3/00
Filed: 1990-01-08
Abstract: Abstract of the Disclosure An electronic article surveillance system which is capable of reliably identifying and discriminating between the different signatures of tags and labels which may come to pass in its vicinity, improving the reliability of the system and even permitting the tags and labels to be classified by type, and separately addressed, includes a receiver for detecting signals resulting from such tags or labels which incorporates improvements in its filtering and processing sections.  A linear phase (constant group delay) filter is used to more effectively preserve the signal which is received, and thereby improve the signal which is ultimately delivered to the processor which follows.  The processor is provided with a "hysteresis-type" threshold detector which operates to further preserve the original signal by improving the shape (width) of the pulse which is ultimately delivered to the processor following conversion from analog form, and an adaptive processing routine which varies the subsequent processing of detected signals according to changes within the system to improve the system's ability to discriminate between the different signals which are received.
