Title: Postiion indicating system and method therefor
IPC: G01S19/11
Filed: 1970-10-23
Abstract: 1321274 Navigation systems TRW Inc 23 Oct 1970 [23 Oct 1969] 50546/70 Heading H4D To overcome the ground reflection &c., distortions which obviate use of a standard radio 1.LS system down to ground level, a source having wavelengths equal to or shorter than visible light is used to provide the overlapping amplitude modulated radiation beam. The only described embodiment uses gamma radiation from a Cobalt 60 radio isotope source. To produce the glide slope 13 or localizer 11 beam pairs, Fig. 1, the radiation system of Fig. 2 is used. The gamma source 14 is contained within a shielded enclosure 15 having a slotted aperture 19 defining the direction and cross-sections, Fig. 3 (not shown) of the two overlapping beams 20, 21. Annular shutters 17 and 18 (see Fig. 4) rotate about axis 9 passing through the source and pulse modulate the beams 20, 21 at 9 Hz and 15 Hz respectively. The airborne receiver, Fig. 5, comprises a scintillator/photomultiplier detector 25 feeding a discriminator 30 and filter 31 to respectively reduce the background noise and unwanted frequencies. The signals from the two beams are separated out by frequency detectors 32 and 33 designed to detect the amplitudes of the 9 Hz and 15 Hz components and send corresponding signals to a differential amplifier 34, which gives a glide slope error signal for application to an indicator 35, e.g. crosspointer. A similar radiation system and detectors 37, 38 gives a localizer error signal. The sensitivity of the detectors 32, 33, 37, 38 is increased by phase locking synchronous signals from a pulser 67 triggered by signals from receiver 66 in response to signals from a remote transmitter 65 occurring during the intervals when shutters 17, 18 allow no radiation to pass. The landing path, defined by the intersection of the glide path beam and the localizer beam may be parabolic whence the localizer beam 58, Fig. 6, is conical and the glide path beam is in a vertical plane. A pair of radiation sources may be used, separated by a shaped wall such that the overlap region has a cross-section corresponding to that of the wall. Radiation sources may be provided in pairs either side of the glide slope path, their beams being inwardly directed to cross and define an overlap region coinciding with the desired glide slope path.

Abstract: 1,029,490. Boiler feedwater heating and supply systems; heating air for combustion. G. & T. WEIR Ltd. Dec. 31, 1963 [Jan. 3, 1963; Feb. 26, 1963], No. 51331/63. Headings F4A and F4B. Waste gases from a high-pressure boiler flow through a duet 1 in which is disposed a coil 2 through which water is pumped by a pump 4 drawing water from a flash evaporator 6, the heated water returning to the evaporator 6 through a line 5 to flash into steam which passes through a pressure control valve 20 and a line 7 to a condensing heat exchanger 8 wherein it heats combustion air for the boiler or, in a modification, feedwater, flowing through the lines 9, 10. Non-condensible gases are vented at 21 whilst condensate is extracted by a pump 12 and returned to the evaporator 6. Part of the condensate may be extracted through a line 13 and demineralization plant 15 for use as make-up water for the boiler, this part being replaced in the circuit by water fed to the evaporator through a line 16 and demineralization plant 18 under the control of a valve 19 actuable to maintain a constant level in the evaporator. The pressure in the evaporator and hence the temperature of the water entering the coil 2 is controlled by the valve 20 so that condensation of corrosive vapour on the coil 2 is avoided. In a modification, two heat exchanger coils are arranged successively in the waste gas stream and are temperature controlled to give the optimum heat regeneration whilst avoiding surface corrosion.

Title: Devices for carrying out a measuring, sampling or treating operation upon a bath of molten metal
IPC: F15B11/08
Filed: 1973-11-06
Abstract: 1398669 Sampling molten metal CENTRE DE RECHERCHES METALLURGIQUES - CENTRUM VOOR RESEARCH IN DE METALLURGIE 6 Nov 1973 [16 Nov 1972 23 Nov 1972] 51479/73 Heading G1B A device for carrying out a measuring, sampling or treating operation upon a bath of molten metal in a receptacle comprises  (a) a probe for carrying out said operation; (b) a carrier on which the probe is mounted; (c) a support structure on which the probecarrier is movably mounted, movement of said carrier allowing insertion of the probe into the receptacle and withdrawal therefrom; (d) automatic means for inserting the probe into the receptacle by movement of the probecarrier; (e) automatic means for arresting the motion of the probe-carrier during insertion, when the probe is at a predetermined position relative to the surface of the bath in the receptacle; (f) automatic means for withdrawing the probe from the receptacle by motion of the probe-carrier when a predetermined length of time has elapsed since the arresting of the motion of the probecarrier during insertion. The device may be operated pneumatically, for example in the arrangement illustrated in Fig.1, wherein there are provided starting control units 1 and 2 linked pneumatically via slide valve distributors 6-10 to a pneumatic cylinder 11 controlling the movement of probe-carrier 17. The probe-carrier 17 and probe 16 are associated with tube 12, said tube functioning as an automatic arresting means. There are also provided sources of compressed air 18 to 27. In operation; depression of push buttons 29 and 30 will result in compressed air from source 22 being fed to the lower portion of cylinder 11, the piston rising and probe and tube falling, thus being inserted into the molten metal bath. A further consequence of the depression of push buttons 29 and 30 is that tube 12 and compressed air source 21 will be placed in pneumatic communication and accordingly, when tube 12 is inserted into the molten metal in the bath, a consequent rise in pressure will occur and will be transmitted via lines 58 and 60 to push button 59, thus causing slide valve 61 to move. This results in the upper portion of cylinder 11 being linked with compressed air source 24. The piston, being subjected to an equal pressure on both sides, will remain stationary. A progressive pressure buildup in reservoir 5 results in slide movement in distributors 6,7 and 9 with coupling of the lower portion of the cylinder with escape regulator 13. The pressure in the lower portion of the cylinder drops and the piston falls to its initial position. The device thus returns to its initial position for further use. In an alternative arrangement, the tube 12 may be made of a material that will evolve a gas on contact with the molten metal. Cardboard is a suitable material. The gas evolved will generate a pressure which will propagate along line 58 to push button 59 and this will arrest the immersion of the probe as described above.

Abstract: 1299601 Automatic current control PLESSEY CO Ltd 28 Sept 1970 [24 Oct 1969] 52190/69 Heading G3R The R.M.S. current supplied to output terminals 2 from an A. C. source 1 via a transformer T1 is maintained constant by varying the firing instant of anti-parallel connected thyristors R1, R2 in accordance with an error signal derived from a comparison of the actual current with a reference signal VR representative of a desired current. The actual current is sensed by a current transformer T2 whose output is rectified by a rectifier 3 feeding a selector 4 which passes a desired proportion of the signal to a R.M.S. detector 5. The output of the latter is substantially proportional to the R.M.S. current taken by the load connected to output terminals 2 and is supplied to a differential amplifier 6 for comparison with the reference signal VR. The output of amplifier 6 is applied to a timing circuit 7 which controls a pulse generator 8 to determine the firing instant of the thyristors R1, R2. The output terminals 2 may supply the lamps on an airfield lighting circuit and the regulator maintains the R.M.S. current constant at a value corresponding to a brilliance selected by the member 4, which comprises a number of shunt paths connected across the output of rectifier 3, each path consisting of a silicon controlled rectifier and a resistor. Selected paths are chosen by triggering the appropriate silicon controlled rectifier using switches in the regulator or in a remote control station.
