Patent GB-1137252-A (GB)
Title: Radar systems
Inventor: CLARKE GEORGE FARREN
IPC: G01S7/292
Filed: 1965-01-13
Abstract: 1,137,252. Pulse radar; aerials. MINISTER OF TECHNOLOGY. 10 Jan., 1966 [13,Jan., 1965], No. 1588/65. Headings H4A and H4D. In a pulse radar, scanning is effected at both the transmitter and receiver aerials. The received signals are subjected to increasing gain as the target range increases and are passed through a clutter canceller so as to detect moving targets only. Each receiver channel contains a storage element in which the received signals excite cumulative damped oscillations. The receiver scans at the Nyquist rate, i.e. the number of receiver scan periods per second is equal to the received signal bandwidth. The transmitter scan track is not connected with the receiver operation. The transmitter beam is a fan-shaped sheet, half a degree thick in elevation, 90 degrees wide in azimuth and is tilted through 10 degrees elevation once per second. The transmitted pulses are a 10 microsecond modulation of a 3000 Mc/s. carrier. The receiver beam is a fanshaped vertical sheet, one degree thick in azimuth and 10 degrees wide in elevation and is swept through 90 degrees in azimuth once during each period of 10 microseconds, i.e. the pulse duration. The intersection of the sheet beams scans over the surveillance area. Tilting of the transmitted beam is effected by interference between the elements A1 to An supplied through the phase shifters P1 to Pn controlled by motor M. At the receiver elements R1 to Rm, the received signals are scanned electronically in the scan wave modulators S1 to Sm coupled to the scan wave generator 16. The outputs of the storage elements El  to Em are provided with attenuators W1 to Wm which weight the signals so as to give the receiver beam the required width. The weighted signals are combined simultaneously in the summing circuit 17, applied to gain controlled amplifier 18, and then fed to the clutter canceller 22 formed of ultrasonic delay lines each having a delay equal to the interpulse interval. The delay line outputs are subtractively combined. The elevation time base 30 is synchronized with the elevation scanning of the transmitter beam and is applied to the search and strobe unit 23 and the tracking units T1, T2, T3 together with the outputs from the range time base generator 29 and the scan wave generator 16 in the receiver. The time base produced by generator 16 establishes the azimuthal bearing of the target from the time of occurrence of the response pulse. The unit 23 comprises plan position indicator-type scans from which signals are transferred to the tracking units T1, T2, T3 by strobe gating and targets will mutually interfere only when they are coincidentally within the same threedimensional cell.

Title: Method and apparatus for preventing oxidation of a metal strip during heating
IPC: C21D9/56
Filed: 1974-01-15
Abstract: 1413944 Strip annealing furnace SELAS CORP OF AMERICA 15 Jan 1974 [26 Oct 1973] 01855/74 Heading C7N [Also in Division F4] A metal strip heat treatment furnace having a plurality of burners is shut down by reducing the fuel supply to the burners to a level lower than normal but substantially above zero and introducing a non-oxidizing protective gas into the furnace, maintaining the gas supply and reduced fuel supply for a predetermined period of time and thereafter shutting off the fuel supply. The strip may be heated by burners in furnace chamber 4 using excess fuel to ensure the absence of free oxygen, passed through horizontal treating chamber 9 containing a neutral or reducing atmosphere in which it is heated by radiant tubes 14 and passed into coating bath 12 containing molten Zn or Al. The strip speed and strip temperature may be measured (e.g. using optical pyrometer 15) and at low strip speeds and high temperatures such as may give rise to overheating of the strip an automatic control system is activated in which the fuel supply to the burners is reduced, nitrogen is introduced into the furnace chamber, damper 21 in exhaust duct 6 is closed to prevent entry of the atmosphere into the furnace chamber and the required amount of air for combustion is introduced into exhaust duct 6. Alternatively the nitrogen may be introduced into the furnace before the fuel supply is reduced. Details of the method of operation of the automatic control system are provided.

Title: Method of manufacturing monocrystalline  semiconductor bodies
IPC: C30B33/00
Filed: 1973-01-15
Abstract: 1414202 Growing crystals with dislocations PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 Jan 1973 [18 Jan 1972] 1999/73 Heading B1S [Also in Division H1] A monocrystalline semiconductor body containing dislocations is made by growing a single crystal of a semiconductor material by deposition from a liquid phase so as to produce a dislocation-free region of crystallized material and then introducing dislocations into the dislocation-free region of crystallized material during the growth of further dislocation free material. The dislocations may be produced by mechanical vibrations or stresses, or thermally. The monocrystalline body may be formed by zone-melting or crystal pulling. The formation of dislocations in the non-dislocated growing crystal formed by crystal pulling may be effected and controlled by creating structural stresses in the shape of the growing crystal e.g. if during growth of the single crystal the conditions of growth during the increase in diameter produce a conical form and if the apical angle of this conical form exceeds a certain value spontaneous generation of dislocations occurs. The Figure shown is a vertical section of a device for drawing crystals using the above method for producing dislocations. The device consists of a cylindrical chamber with quartz glass walls 1, a bottom 2 and a lid 3. The chamber contains an outer crucible 9, supported by 8, and is inductively heated by coil 12 connected to generator 22. Crucible 9, contains an inner crucible 10 with a stem 13 passing through aperture 14 in the outer crucible. The stem 13 is connected to a weight 15. The inner crucible can be raised or lowered and also can rotate about stem 13 in the outer crucible. Material to be crystallized which is contained in outer crucible 9 passes into the inner crucible 10 via duct 16 connecting the crucibles. The crystal drawing rod 4 includes a seed crystal holder 11. In an example of the method using this apparatus, pure germanium is melted in crucible 9 and flows via duct 16 into inner crucible 10 which contains indium as a dopant and the crucible is pulled down into the melt 38, by weight 15 until the upper surface of 10 just projects above the melt. The drawing rod 4, containing a [111]-germanium seed crystal at 30, is lowered until it contacts melt surface 31. The initial diameter of the grown crystal 32 is 2 mms and when 10 mms in length of this crystal has been grown, the diameter of the crystal is increased by temperature and drawing rate control and a conical part 34 having an apical angle of 40‹ formed. Just before the conical part 34 reaches a diameter of 45 mms the temperature of the melt 31 is increased whereby the conical part 34 changes at 35 into a cylindrical portion 36 and dislocations are generated in the already crystallized material. The average dislocation density is from 200 to 2,500 dislocations per sq cm. The germanium crystal is used in the manufacture of lithium-drifted radiation detectors suitable for measurement of γ-radiation and X-rays.
