Abstract: ABSTRACT OF THE DISCLOSURE An improved indicator of the condition of an interrupting device in a high voltage circuit Released stored energy opens closed contacts of the device which is at line potential to prevent current flow. The energy is restored when the contacts close. A shunt trip, responding to circuit conditions or to remote command, can release the stored energy. Manual movement of an actuator can both also release the stored energy and reclose the contacts following their opening by the shunt-trip or by the actuator. Operation of the shunt-trip does not affect the actuator and vice versa. The indicator includes an arrangement at ground potential which mimics the putative condition of the contacts depending on the condition of the shunt-trip and the actuator. Specif-ically, the actuator responds to a lack of contact-opening operation of either the shunt-trip or the actuator by giving a sensible indication that the contacts are putatively open. Lastly, the indicator gives a sensible indication of any contact-closing operation of the actuator while such is taking place.

Abstract: ABSTRACT            TITLE:  "METHOD OF RECOVERING VOLATILE METALS FROM          MATERIAL CONTAINING METAL OXIDES"     A method of reducing and recovering volatile metal from metal oxides comprising the steps of injecting metal oxide-containing material into a shaft reactor, simultaneously injecting reducing agent into said reactor, continuously maintaining said reactor substantially filled with coke, supplying thermal energy to the reactor, preferably by means of a plasma burner, such that at least some of the metal oxides are reduced to metal and melted or volatilized depending upon whether the metal is volatile.  The melted metal is removed from the bottom of the reactor while the volatilized metal is permitted to flow upwardly through the shaft reactor in the form of metal vapour together with a gas flow.  The coke in the shaft reactor through which the volatilized metal passes is maintained at a temperature in excess of 1000°C, thus screening the upper portion of the shaft reactor and the reactor top by means of the coke so as to prevent condensation of the volatilized metal.

Abstract: Abstract:     A bag of tough, flexible material, sealed to be liquid tight except for filling and emptying access ports, is de-signed for mounting in a standard transportation container. The bag is then filled with a bulk liquid and transported in the container to a desired destination where it is again emptied.  To avoid the transportation cost of returning many such bags to the point of origin, while nevertheless not simply discarding them, the present invention provides the third alternative of so constructing each bag that, after use, it can be cut to become suitable for use as a tarpaulin. For this purpose the bag is constructed of a central, generally cylindrical, elongated portion extending at each end into a curved end portion.  Tie down devices, i.e. flaps each containing a rigid eye for receiving a tie down rope, are arranged in a pair of circumferential rows extending around the periphery of the central portion near each end portion and in a further pair of adjacent parallel rows ex-tending longitudinally along the central portion between the circumferential rows.  By cutting the used bag longitudinally between the latter pair of rows and peripherally outwardly of the circumferential rows, the central portion is trans-formed into a rectangular sheet with the tie down devices disposed around its periphery.

Abstract: ABSTRACT OF THE DISCLOSURE         A total raster error measurement and correction circuitry, using digital memory means in the camera head for the storage of correction data, corrects spatial scan, shading, etc., errors in a television picture in two dimen-sions.  The basic spatial error correction circuit effectively synthesizes horizontal rate waveforms on a number of discrete lines of the vertical scan.  On all scanned lines between discrete lines, a linear approximation between the two discrete waveforms is made to form a vertically continuous waveform.  Black and white shading errors are measured by comparing the black and white video levels against respective selected black and white D.C. levels with and without a cap on the camera lens.  Gamma correction is provided by comparing the peak black and white levels to derive any gray level errors.  The total raster error correction data are retrieved from memory and are applied to given image pickup sensors and corresponding video processing circuits in the camera head system during real time operation.

Abstract: Abstract of the Disclosure A probe is constructed for placement in the hot tur-bine section of a gas turbine engine.  A housing contain-ing two electrodes extends through the turbine shroud into the tip clearance area of the turbine rotor.  A voltage im-pressed across the electrodes will generate an electric field in the vicinity of the turbine blades which will be distorted as the blades pass, thereby generating a charge pulse at the output of the probe.  The electrode conductors are imbedded in pins which are retained by insulating rings brazed in place.  The electrodes extend slightly outward from the surrounding insulating surfaces to create an air gap around each electrode.  This air gap provides addition-al insulation and prevents contamination.

A scanning or control panel is electrically connected with the detecting stations by means of four wires extending from the panel regardless of the number of detecting stations utilized in the system.  Two of the four wires are power and return leads from the scanning panel to all of the detecting stations, a third wire provides an interrogation pulse with the first detecting station receiving an interrogation pulse from the scanning panel and each succeeding detector station receiving an interrogation pulse generated by the preceding detector station at a predetermined later time following receipt of the interrogation pulse from the preceding detector station, and the fourth wire carries a pulse train of timewise spaced data pulses genera-ted by the detecting stations in response to receipt of an interrogation pulse.  Each data pulse generated by each detecting station is controlled as to pulse width so as to be indicative of the presence or absence of the con-dition being monitored, such as the presence or absence of a fire.  The data pulses are processed at the scanning panel and an alarm generated if the pulses are indicative of a sensed condition such as a fire.  Provision is also made for visually indicating the location or locations of all sensed conditions causing the alarm.
