Title: Wide range regulated power supply
Inventor: CHURCHILL F
IPC: H02M3/335
Filed: 1971-03-04
Granted: 1973-10-16
Abstract: A fly-back type power supply includes a transformer, the primary winding of which is periodically connected to a DC source to establish current through such winding, When this current increases to a predetermined optimum value, the current flow through the primary winding is interrupted for producing collapse of the transformer's magnetic field and generation of an output in the transformer's secondary windings. The frequency at which the primary is periodically connected to the DC source is controlled by a secondary output voltage such that the frequency is increased when such output voltage tends to decrease. A plurality of secondary windings are each connected to a rectifier and filter capacitor combination, wherein the filter capacitors are coupled in series for production of a high voltage output.

Abstract: Abstract of the Disclosure A ground fault current detection and disconnect device.  A differential current sensing transformer is employed together with a second transformer having one winding in series with the neutral conductor and another winding serving as an auto-transformer with a part thereof coupled across the line and neutral conductors.  The auto-transformer provides an alternating current power supply to a diode bridge, the output of which pro-vides a direct current power supply for an operational amplifier.    The output of the sensing winding of the differential transformer is an input to the operational amplifier.  When the output of the operational amplifier exceeds a predetermined level, an SCR is triggered on and a circuit disconnect device, bridged across the line and neutral conductors in series with the anode and cathode of the SCR, opens the power supply to the load.  Circuit elements are provided to limit the effects of surge currents and line dis-turbances.  A test switch is provided to introduce a known line unbalance and test the circuit operation and disconnect ability.

Abstract: Abstract of the Disclosure A spark gap arrangement is provided ior a television image reproducing system including a television picture tube having a relatively high voltage focus electrode and relatively low voltage cathode, screen grid and control grid electrodes.          Spark gaps are respectively coupled between the electrodes and a reference potential to discharge energy deveoped at thc electrodes when undesirable arcing occurs between the electrodes which might otherwise cause damage to respective portlons of the signal processing system coupled to the electrodes.  Separate relatively low impedance paths for conducting discharge currents produced in the spark gaps are coupled to the spark ?ap associated with the relatively high voltage focus electrode and the spark gaps associated with the relatively low voltage cathode, screen grid and control grid electrodes to substantlally prevent arc discharge currents associated with the focus electrode from being coupled to the cathode, screen grid and control grid electrodes through the spark gaps associated with the relatively low voltage elec-trodes themselves.  In addition, the spark gaps are designed to inhibit excessively high voltages developed at the focus electrode from discharglng to adJacent electrodes, thereby circumventing the purpose of the separate discharge path arrangement, rather than through the associated spark gap.

Abstract: Abstract An infrared line scanning instrument is provided which scans a single line in a field of view of the instrument.  The scan is performed by a scanning mirror which is transparent in the visible and reflective in the infrared region of the spectrum. The infrared radiation is applied to an infrared detector which feeds a display in the form of a light-emitting diode array to light an element in the array in accordance with the amplitude of the IR irradiance seen by the instantaneous field of view throughout the scan.  The display is superimposed from the back side of the scanning mirror upon the visible field of view seen by the observer and/or a camera.  The instrument thus generates a record of the thermal profile of a single line of a viewed target which is spatially correlated with its location on the target.

Abstract: MACHINE TIMING SYSTEM          ABSTRACT OF THE DISCLOSURE         An improved timing system for an indexing type of article inspection machine.  Inspection machines which index articles through a plurality of inspection stations require a timing signal to turn various machine functions on and off.  A shaft encoder generates a plurality of pulses for each machine cycle.  A single pulse is also generated to signal the beginning or  end of a machine cycle.  The multiple pulses are counted, stored, and a number representative of the total stored count is presented as an output signal quantity.          A series of logic circuits turn the machine functions on and off in response to the output signal quantity reaching specific, pre-selected values.  These values may be calibrated as a percentage of the total cycle time for each machine cycle.
