US Patent:

42766109, Jun 30, 1981

Filed:

Jan 26, 1979

Appl. No.:

6/006576

Inventors:

William C. Fleck - Palisades Park NJ

Assignee:

Intraspec Inc. - Bogota NJ

International Classification:

G06F 303
G06F 3153
G05B 1910

US Classification:

364900

Abstract:

Programmable sequencer apparatus for enabling an operator to selectively establish sequential energizing patterns for a plurality of outputs and thereafter for causing said plurality of outputs to be selectively energized in the sequences defined is set forth in accordance with the teachings of the present invention. According to a preferred embodiment, programmable sequencer apparatus is provided for controlling the selective energization of a plurality of outputs under conditions where any of the plurality of outputs may be selectively energized as a step of a sequence, a group of steps may be established in a sequence to define a programmed operating formula for equipment to be controlled and a plurality of operating formulas may be established to accommodate various modes of operation. A light emitting diode is provided to designate an energized state for each of the plurality of outputs, and indicators are provided to display the step, time of operation for that step and the formula being programmed or initiated. During a program mode, the step and formula being programmed is displayed and each light emitting diode is illuminated in sequence.

Appl. No.:

6/395136

Inventors:

William C. Fleck - Palisades Park NJ

Assignee:

Chiu Technical Corporation - Kings Park NY

International Classification:

G05F 100
H05B 4116

US Classification:

315287

Abstract:

A power supply for a gaseous discharge lamp in which power adjustments are made automatically to insure that rated lamp power is delivered regardless of changes in lamp impedance or line voltage which may occur. A high D. C. voltage is delivered to a step down low hysteresis transformer and electronic switching is provided to obtain a high frequency pulsed flow to the primary of the transformer. Sawtooth waves are generated and peak current is utilized to regulate closely power input to the transformer. A feature is the use of a programming resistor to select the desired power level for the particular gas discharge lamp.

William C. Fleck - Oakland Gardens NY

Chiu Technical Corporation - Kings Partk NY

International Classification:

H02H 900

US Classification:

361 54

Abstract:

A filament bypass circuit for use with a string of lamps in series capable of continuing current flow when a lamp in the string fails. Each lamp is provided with a shunt circuit consisting of a series circuit of a diode and a silicon bilateral voltage triggered switch. The switch becomes conductive upon the application of a substantial increase in voltage from the A. C. source and remains conductive until there is an interruption of current flow or current flow drops below its required holding value. The diode insures that during continued operation after a failure there will not be an excessive voltage applied to the remaining lamps, and also serves as an indicator of a failed lamp.
