Title: Improvements in and relating to magnetrons
IPC: H01J25/54
Filed: 1947-09-15
Abstract: 657,487. Magnetrons. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 15, 1947, No. 25219. Convention date, June 23, 1945. [Class 39 (i)] A magnetron comprises a parallel conductor transmission line 5, 6, Fig. 1, extending through the envelope 1 and terminated inside the envelope 1 by a loop 2, two anode segments 9, 10, are connected to different conductors of the line and a third anode segment 14 is connected to the loop 2 at a neutral point. The transmission line 5, 6, preferably of copper, is sealed through fernico sleeves 3, 4 and is provided with a movable short-circuiting conductor 8 outside the envelope 1, for tuning. A cathode 18 of tungsten wire is carried from rigid leads 20 by resilient members 19, and shields 22 are mounted at either end of the anode segments on the members 19 to protect the glass envelope wall from electron bombardment. A further shield 24 is attached to anode segment 9, and a getter 25 is provided. " Neutrode " 14 subtends 180 degrees and segments 9, 10, 90 degrees each at the cathode. The D.C. anode terminal is connected at 27, and the magnetic field is produced by a permanent or electromagnet (not shown). The distance between short-circuiting member 8 and anode segments 9, 10 is a half wavelength or any multiple of a half wavelength. In a modification, Fig. 3, the anode segments 28, 29 have end portions 30, 31 projecting radially towards the cathode and each subtending angles of 51.4 degrees thereat. A shield 34 is provided, similar to shield 24 in Fig. 1. In a further modification, Fig. 5, anode segments 35, 36 are L-shaped and each subtend 60 degrees at the cathode. In a further modification, Fig. 7, segments 41, 44 are both " neutrodes " and are connected together by two conductive annuli 45. The cathode 47 has an extension integral therewith connected to a support similar to 19, Fig. 1. Segments 39, 40 arranged between the two " neutrodes " each subtend 36 degrees at the cathode. The Specification as open to inspection under Sect. 91 states that in the form of Figs. 7 and 8, the cathode is located in a recess in a cylindrical member concentric with the anode segments. In all forms the transmission line and anode segments may if desired be formed from a single conducting block though the built-up structures illustrated are preferred. The mode of operation of the devices is compared with that of multi-resonator magnetrons with specified numbers of interaction gaps. This subjectmatter does not appear in the Specification as accepted.

Abstract: 919,822. Reactors. ROLLS-ROYCE Ltd. Oct. 2, 1959 [Aug. 6, 1958], No. 25269/58. Class 39 (4). In a nuclear reactor fuel channel, baffles are mounted at the inlet and outlet which permit the flow of coolant steam but intercept the neutron and gamma radiation directed axially along the channels. As shown, the fuel element cluster 11 is held in the thin stainless steel tube 14 supported in the aluminium tube 28. The cooling medium, steam, passes downwards through 14 and the annular space 19 is filled with CO 2  or He at a pressure equal to that of the steam. The CO 2  or He serves to heat insulate 28 from 11 while the tube 14 is not stressed, having equal pressures at the two surfaces. The baffles 20, at each end of 14, are shaped to prevent straight line flow to or from the element 11 and may be formed of iron, steel or lead, if the temperature is low enough. They may also be in the form of a Maltese Cross or twisted drill. Control of the reactor is effected by adjustment of the level of the heavy water moderator within a container in the reactor core. Specifications 849,143 and 916,324 are referred to.

A braiding machine bobbin 19 of the ratchet let-off type has a ratchet base 15 connected to one of its flanges 12 by a resilient connection 14. As shown, an annular resilient disc 14, e.g. of rubber, is bonded to flange 12 and disc 15a which latter has teeth 15b. Alternatively, compression springs may be provided instead of disc 14. Flanges 11, 12 secured by pins 13b, to a sleeve 13, of which a reduced portion 13a projects through flange 12 form bobbin 19 which is located on a spindle 16 by a sleeve 21. The ends of a latch 18a pivoted on sleeve 21 respectively engage teeth 15b and the end of a spring- biased rod 18b. Two parallel pillars.22 on a base-plate 17 each carry a compression spring 20b which extends between a block 20a sliding on the pillars and a web 23 carrying a guide 24 and a support 23a for the end of spindle 16. Parallel pulleys 25 and 26 are secured respectively to block 20a and a fixed lug 18d. A cam follower assembly 28 secured beneath plate 17 engages a cam slot of a braiding machine. In operation, a wire from bobbin 19 passes round pulleys 26 and 25 and through guide 24 to the cable being braided. Any increase of tension in the wire will draw the pulley 25 axially of pillars 22 until block 20a engages member 18c and displaces rod 18b to disengage latch 18a from ratchet teeth 15b and allow the bobbin to rotate freely to reduce the tension. Block 20a then moves downward, rod 18b returns to its initial position and latch 18a re-engages teeth 15b to brake the bobbin's rotation.

Abstract: Sweet cracked naphtha of improved oxidation stability is produced by contacting the sour naphtha at 70-90 DEG F., and in the presence of 3-9 SCF of free oxygen/lb. of mercaptan sulphur in the naphtha, with a granular catalyst comprising cupric chloride, water and a carrier, and adding 0.5-10 lbs./1000 barrels of naphtha each of a phenylene diamine and a metal deactivator to the sweet naphtha.  The carrier contains 15-25 wt. per cent of water and the weight ratio of carrier to cupric chloride is between 12:1 and 15:1.  The cupric chloride may contain sodium or ammonium chloride.  Carriers referred to are fuller's earth and Attapulgus clay.  The sour naphtha should be free of hydrogen sulphide, which may be removed, e.g. by washing with dilute aqueous caustic alkali solution.  Alkali may be removed by passing through a salt filter or through steel wool, gravel or sand. The sour naphtha may also be treated in a solutizer process to remove part of the mercaptans present.  The sweet naphtha may be water-washed and passed through a salt filter.  The cracked naphtha may be derived from the thermal or catalytic cracking of gas oils, reduced crudes or heavy naphthas; mixtures of a major proportion of cracked naphtha together with virgin naphtha may be used.  Phenylene diamines referred to are N, N1-di-isopropyl, N, N1-di-sec-butyl, N, N1-di-amyl, N, N1-dihexyl, N-propylN1-butyl, N-butyl-N1-amyl and N-hexylN1 - octyl p - phenylene diamines.
