Patent number: 4434569Abstract: A connector is fabricated from dielectric material, typically ceramic, to enable the isolated assembly of neon connections, the plugging in of neon tubes, and the maintenance of high voltage neon connections (in the order of 30,000 volts). The connector includes a dielectric housing and separate dielectric cover plate with an optional silicon rubber gasket therebetween. In connector assembly, commonly bound, oppositely-polarized high voltage wires enter a common chamber defined between the backside of the housing and the mounting. On the front side of the housing are first and second paired and communicated chamber sets. Each set of chambers includes a connector chamber and a tube receiving chamber. The connector chamber receives an insulated wire of one polarity from the common housing at the connector back and provides an isolated dielectric cavity in which the wire is stripped and electrical conductor connection made.Type: GrantFiled: June 11, 1981Date of Patent: March 6, 1984Inventor: Robert W.

Patent number: 4430846Abstract: The present invention provides an electrohydraulic control, which includes both an electrohydraulic valve (36) and an electronic control (382). The electronic control includes an offsetting circuit (622) and is effective to produce an effective driving voltage, for an electrical force-motor (52) of the electrohydraulic valve, that is pulse-width-modulated and that is greater than a fixed proportionality to an input signal (410) by a manually adjustable offset voltage. The offset voltage may be adjusted to produce a null force that exactly balances a spring (129) which presses the valve spool (54) to an overlapped position; so that fluid flow is proportional to an input signal irrespective of the initial load of the spring.Type: GrantFiled: January 15, 1982Date of Patent: February 14, 1984Assignee: Electro-Hydraulic Controls, Inc.Inventors: Glen T. Presley, Lloyd L. Lautzenhiser

Patent number: 4429478Abstract: The variable information sign includes, in one embodiment, a display board 10 having a smooth and nonporous display surface 10A, a carriage 12 supported from and movable with respect to display board 10, a plurality of print modules 14 that are supported by carriage 12, an erase roller 16 also supported from carriage 12, and a re-inking station 18 supported from display board 10 and located at one side thereof. Each of the print modules contains a supply of a dry erase ink which is located into the print module when the carriage is in proximity to the re-inking station. As the carriage is caused to move in a predetermined direction, each of the print modules is deactuated and the erase roller wipes the display surface to remove any previously-printed information.Type: GrantFiled: June 26, 1981Date of Patent: February 7, 1984Inventor: James Bruce-Sanders
