Abstract: A capacitance-type membrane switch in which ordinarily spaced-apart contacts are positioned other than directly over an associated capacitance spacing element with an inner insulating layer and outer conductive portions.

Abstract: Detection circuitry for a capacitance switch including a source of two-state electrical pulses that are supplied to two clock nodes 180.degree. out of phase, a buffer connected to one of the switch connection nodes, means between the clock nodes and the switch connections to maintain the buffer input at one condition when the capacitance switch is closed and to cause the buffer input conditions and the buffer output signal to vary with the two-state pulses when the capacitance switch is open, and a frequency detector connected to the buffer output.

Abstract: A graphics-bearing element is provided in which improved durability in liquid environments is provided through inclusion in a graphics layer of polyvinyl formal resin.

Abstract: An electroluminescent display device is provided in which electroluminescent portions are defined by first laying down a layer of electroluminescent host material and thereafter doping this layer in selected portions with an electroluminescent activator.

Abstract: A capacitance switch in which a capacitance spacing element is bent around an end of a spacer centrally relieved for strain relief.

Abstract: A capacitance-type switch in which an integral capacitance spacer layer element extends over and is severally movable toward and away from separate contact elements of separate switches.

Abstract: An electroluminescent display which includes a thin film layer of a material which, if undue current passes through a portion of it, that portion is converted from a semiconductor into an insulator.

Abstract: A capacitance-type membrane switch is provided in which it is practical to seal the switch against dust and fluid.

Abstract: A sleeve marker assembly (10, 50) of sleeve markers (11, 53) formed by a base web (12) and top web (13) joined together by transverse seals (16). The base web and top web are of the same width, and two or more rows of spaced longitudinal slits (18, 21, 51 & 52) extend through both webs to define open ends of the sleeve markers. The sleeve markers are manually detachable from the assembly for application to an article.

Abstract: An assembly of tubular sleeve markers formed by one or more top webs joined to a base web along transverse seams. The top webs are narrower in width than the base web. The base web has opposed marginal edge portions that extend beyond the top webs. Separable line means are formed in the base web in the marginal edge portions. The sleeve markers are individually detachable from the assembly.

Abstract: A laminated reed switch assembly in which the reed is movable between two positions, in one of which it contacts two pole pieces.

Abstract: A kit for making custom prototype membrane switch panels which includes a plurality of switch units and an overlay unit for integration and protection of said switch panels and indicia carried thereby.

Abstract: A multi-layered flexible switch wherein the electrical contacts are transversely remote from the area of the switch to be depressed.

Abstract: A tape package for a roll of adhesive tape having a cover element joined to a base member. The cover element is formed to have a housing portion including a circular wall. A friction ring is carried on the circular wall and engages the inner core surface of the roll of tape.

Abstract: A tape package for a roll of adhesive tape having a cover element joined to a base member. The cover element is formed to have a housing portion that includes a dentate vertical wall on which the roll of tape is supported.

Abstract: A tape package for a roll of adhesive tape having a cover element joined to a base member. A friction disc is attached to the base member and arranged to engage an end surface of the roll of tape.

Abstract: A multilayer display device with thin-film transistor circuits for sequentially switching a common brightness control signal to a plurality of individual display elements.

Abstract: A multi-layered membrane switch having a spacer layer with one or more tabs extending across the width of its cut out portion to provide support for an upper contact supporting layer.

Abstract: A marker sleeve assembly (1) comprising a plurality of marker sleeves (2, 3, 4, 5, 15 or 16) each joined to a longitudinal connecting member (6 or 6'). The connecting member is formed integrally with the marker sleeves and is attached to the outer wall of each sleeve in the assembly. The marker sleeves are detachably joined to the connecting member so that an individual marker sleeve can be removed from the connecting member for application to an article.

Abstract: A flexible switch with a flexible tail bent downward from the switch inside the edge of the switch and placed through an opening in the frame supporting the switch, the tail carrying conductive leads for connecting contacts carried by layers of the switch to external circuitry, thereby allowing for an uninterrupted peripheral adhesive seal between the switch and the underlying frame.
