Title: Arrangement for the detection of faults on moving tapes
IPC: G01N21/89
Filed: 1979-04-19
Abstract: An arrangement for the detection of surface faults in the form of streaks on continuously moving webs comprising a source of light (206) for illuminating the web and a light receiving device (at 211) arranged at the angle of reflection. The source of light provides a substantially rectangular area of illumination on the tape having two sides parallel with the direction of movement (203) of the tape. The width of the rectangle is about twice the greatest expected width of the streaks. The streaks are detected by observing or recording the change in intensity of illumination in a plane of observation passing through the radiation field parallel to the web, using a ground glass screen, a magnifying lens, an image tube and photographic film or a slit and photodetector to scan the observation plane. <IMAGE>

Title: Gas turbine engine air bleed
IPC: F02C6/08
Filed: 1979-05-08
Abstract: An auxiliary airflow for powering accessories obtained from the compressor of the engine via a bleed aperture 7 immediately downstream of a diffuser vane 3 in a cusp 6 which is formed in the trailing edge of the vane 3 to provide inertial separation. The high energy air from the diffuser 1 is used as the primary airflow in an ejector 10 to draw ambient air into the auxiliary airflow to lower the temperature of the bleed air. The ejector automatically adjusts the amount of ambient air according to the energy of the bleed airflow by means of a piston-actuated spike 13 mounted for sliding movement in the primary nozzle 11. The spike 13 varies the volume of flow through the primary nozzle 11 according to the pressure exerted by the airflow on the piston. <IMAGE>

Title: Mean-phase indicating apparatus and optical-scanning imaging equipment utilising the same
Inventor: MOORE WILLIAM THOMAS
IPC: H04N3/09
Filed: 1981-01-30
Abstract: Apparatus is provided for producing a signal indicative of the mean-phase of corresponding pulses in two pulse trains (P1,P2) which have, on average, the same pulse repetition frequency. The apparatus comprises two current sources (TR1,TR2) each of which is enabled by each pulse of a respective one of the two pulse trains (P1,P2). The outputs of the current sources (TR1,TR2) are connected to a storage capacitor (C). A voltage detector connected across the capacitor (C) generates an output signal (PM) upon the capacitor voltage (V) reaching a predetermined value. The time of generation of this output signal is dependent on the mean time of receipt of corresponding pulses from the two pulse trains (P1,P2) and therefore on their mean phase. The apparatus can be used in imaging equipment which incorporates two reflecting polygons driven to present reflecting faces at the same frequency, the apparatus providing a signal (PM) indicative of the mean phase of presentation of the reflecting faces.   <IMAGE>

Patent GB-2087573-A (GB)
Title: Line signal fault detection system
IPC: G01R31/55
Filed: 1981-11-13
Abstract: In a railway signaling system supply frequency currents from traction feeders for example are induced into signal circuit pairs. Normally the induced emfs are equal and opposite in the two wires and cause no circulating current. In the case of a fault on one of the wires such as to unbalance the circuit, the induced emfs become unbalanced and supply frequency current circulates, causing signaling errors. A tone at the supply frequency is chopped by a square wave and transmitted on the signal circuit. A detector responds to the on/off tone and maintains the signaling circuit in operation. In the event of a fault the induced supply frequency current interferes with the imposed tone and causes the detector to trip so indicating a fault and disabling the signaling circuit. <IMAGE>

Title: Surge voltage protection arrangements
IPC: H02H9/06
Filed: 1982-02-24
Abstract: A surge voltage protection arrangement for a load 10 connected to an A.C. supply 8 comprising a gas-filled excess voltage arrester 11 connected in series with a capacitor 12 across the load 10. The value of the capacitor 12 is chosen such that the largest expected surge pulse which causes the arrester 11 to fire will not charge the capacitor to such an extent that the voltage then applied across the load 10 exceeds that of the A.C. supply 8. The arrangement enables the arrester 11 to recover after such a surge pulse within a fraction of an A.C. supply cycle, thus avoiding placing an unnecessary load on the arrester. A resistor 13 whose resistance is of a value such that the capacitor 12 is able to discharge through it within one half cycle of the A.C. supply may be connected across the capacitor 12. <IMAGE>
