Title: Electromagnetic waveguides
IPC: H01P11/00
Filed: 1972-11-21
Abstract: 1440933 Making waveguides; extruding BICC Ltd 20 Nov 1973 [21 Nov 1972] 53700/72 Headings B3A and B3P [Also in Division H1] A method of making a waveguide of circular cross-section comprises forming a composite tubular billet of circular cross-section by introducing into or forming within a pre-formed tubular sheath 1 a continuous wall 2 of a metal or alloy suitable for forming the electrical conductor of a waveguide, the metals or alloys of the sheath and wall being mutually compatible, extruding the billet between a die 14 and a mandrel 8 to form a composite tubular shell in which the wall is metallurgically bonded to the sheath and applying a layer of insulating material to the internal surface of the shell. The sheath is of aluminium alloy and a seamless copper or silver lining is inserted inside it, preferably in a non-oxidizing gas atmosphere, e.g. nitrogen, after the mating surfaces have been cleaned. The inserted wall is sealed to the sheath by inwardly deforming the sheath at a tapered end 4 and outwardly deforming the wall at the other end of the sheath or by means of a sealing ring (7), Fig. 3 (not shown), in the end face of the sheath. The mandrel 8 is inserted in the prepared billet and it is sealed to the stem 9 of the mandrel by further inward deformation. Alternatively the mandrel stem may have an enlarged end (11), Fig. 7 (not shown). The billet/mandrel assembly is placed in a chamber 13 of a hydrostatic extrusion machine with its end 3 in sealing engagement with the die 14 and pressure of the fluid in the chamber is raised by a ram 15. A head 10 on the mandrel transmits a secondary force on the billet and the mandrel advances through the die as extrusion proceeds. Alternatively a shoulder (16), Fig. 7, may be located in the chamber 13 to hold the mandrel stationary. The mandrel is then removed and an insulating sleeve is inserted in the billet, the sleeve and/or the bore of the billet having a coating of adhesive. The sleeve is sealed to both ends of the billet and the space between the sleeve and billet is evacuated. Fluid under pressure may also be injected into the sleeve bore. Alternatively the bore of the billet is heated and powdered plastics material is applied to it. Another method of forming the composite billet comprises electroplating a layer of copper on to the internal surface of an aluminium or aluminium alloy sheath. This may be effected after depositing a layer of zinc or copper-tin alloy on the internal surface of the sheath. The bond resulting from electro-plating is consolidated by the extrusion process.

Title: Runway traffic surveillance device
IPC: G01S13/91
Filed: 1971-11-25
Abstract: 1366154 Pulse radar INTERNATIONAL STANDARD ELECTRIC CORP 25 Nov 1971 [30 Nov 1970] 54779/71 Heading H4D The signals from the radar system of Specification 1,340,582 giving data about tracked targets, are fed to temporary storage means. If an alarm signal, corresponding to an undesirable or accident situation, is given then the data concerning the target causing the alarm and preceding the occurrence of the alarm by a set interval, is stored permanently. The circuit of Fig. 2 (not shown) provides target velocity V, acceleration γ, angular deviation ## with respect to the runway axis, distance of target to touch down d, and time t from the start of tracking, in both analogue and digital form. The signals are then fed to the recording apparatus, e.g. of Fig. 3. In this example analogue signals ta1 &c. are used corresponding to a target 1. The apparatus of Fig. 3 is duplicated for the other tracked targets. An OR circuit 53 is fed with selected outputs of circuit (24) (Fig. 1, not shown) corresponding to various alarm situations. The target data is fed to gate 50, normally open to record circuit 46 and head 47 which records the data along several tracks on magnetic tape 45. The tape is driven by unit 46. The recorded data is eventually erased by head 49 fed via normally open gate 51 with erase signal Ve. If an alarm signal occurs OR gate 53 and inverter 52 close gates 50, 51. Hence no new data is stored and the recorded data is not erased. The data on the tape is therefore the data concerning the target causing the alarm and preceding the alarm by a time equal to the recording time capacity of the tape. In the Fig. 4 embodiment digital data tn1, tn2 &c., corresponding to two tracked objects is multiplexed, by 54, 55 and clock pulse signal T<SP>1</SP>, on to two tracks of magnetic tape 57 via head 59. The tape is driven by 58, the signals being read at 61 and then erased at 60 after an interval T1 following their recording. Normally no alarm signal is received and bi-stables 74, 73 have zero outputs. AND gates 64, 65 are therefore off and the data from read circuits 62, 63 is not passed to circuits 66, 67. In addition, OR gate 77 gives no output and therefore unit 70 is off, tape 69 therefore being at rest. If an alarm signal occurs, e.g. A5.2, circuit 78 is triggered, the circuit providing a pulse at T1 after triggering. Bi-stable 74 is also set and hence drive unit 70 is switched on, the tape being moved in the direction shown. Bi-stable 74 also switches on AND gate 64 after a delay R, the delay ensuring that tape 69 reaches full speed before recording takes place. Data from 62 is therefore read on to tape 69 and proceeds until 78 provides a pulse to reset 74. Tape 69 therefore stops and AND gate 64 is closed. Data concerning the alarm causing target and preceding the alarm by a time T1-R is therefore recorded on tape 69.

Title: A method of and apparatus for sorting crystals according to size
IPC: B01D9/00
Filed: 1969-11-11
Abstract: 1,271,530. Classifying crystals; centrifuge. C.O.C.E.I. S.A. and F. LAURENTY. 11 Nov., 1969 [15 Nov., 1968], No. 55012/69. Headings B1G, B2H and B2P] A method of classifying crystals comprises feeding them in a carrier fluid from an inlet 14B to a space 11B adjoining a stream of a second fluid from an inlet 14A to a space 11A, across which junction S there is a force causing the crystals to migrate to the second fluid, and opposing this movement by restricting the outlet 15A of the second fluid and enlarging the outlet 15B of the carrier fluid so that there is a current 40 of fluid across the junction S opposing the force; the crystals are thus distributed according to size between the two fluids. The density of the second fluid may be higher than that of the carrier fluid, but is less than that of the crystals; alternatively, the apparatus of Figure 3 may be inverted, and fluids which are more dense than the crystals may be used, in which case the crystals tend to float. The effective area of the junction S may be altered, either with pivoting shutters 13 controlled by a rod and lever, cord, or notched rod (Figures 4A-D, not shown), or with an inflatable chamber (55) (Figure 5, not shown). Several apparatuses of the type illustrated in Figure 3 may be connected in parallel (Figure 6, not shown). In an alternative embodiment (Figures 7, 8) the force is centrifugal rather than gravitational. A wheel 60 is mounted by fluid bearings 68, 69, and is rotated by the second fluid, which enters tangentially from nozzles 114A, strikes blades 64 on the wheel, enters axial passages 66, and proceeds as a rotating cylinder of fluid to the outlets 115A. The carrier fluid and crystals enter at inlet 114B and are rotated by blades 63 on the rotating wheel. The resulting centrifugal force causes crystals to migrate into the second fluid across the junction S', a movement which is opposed by a counter-current induced by restricting the outlets 115A. The second fluid may alternatively enter in front of the wheel (Figure 11, not shown), an axial thrust bearing (76) being provided. In further embodiments (Figures 12, 13, not shown) the wheel presents a concave deflecting surface to the carrier fluid, and is rotated by a prime mover. The apparatus for performing the method may be included in a crystallization circuit, the second fluid consisting of unsaturated liquor rich in dissolved product, and the carrier fluid being dilute liquor carrying crystals.

Abstract: 1,155,400. Pretreating molecular sieves. STAMICARBON N.V. 8 Dec., 1966 [13 Dec., 1965; 14 Sept., 1966], No. 55096/66. Heading B1L. Molecular sieves used for the separation of gas mixtures containing unsaturated hydrocarbons are pretreated to prevent polymerization by contacting the sieve with H 2 S, a C 1 _ 5 - mercaptan or a dialkyl sulphide containing 2-6 carbon atoms, and then desorbing the sulphur compound from the sieve at 200- 700C. The preferred sulphur compounds used in the pretreatment, have molecular weights not above 100. The effect of the treatment is stated to be permanent. In an example, Ca-Na zeolites pretreated with H 2 S, methyl mercaptan and dimethyl sulphide were used to separate a mixture comprising isobutane, isobutene, n-butane and n-butene at 20-70C, the amount of polymerization resulting being very low.

Abstract: 1,255,979. Projectile fuzes. E. LACROIX. 12 Nov., 1969 [13 Nov., 1968], No. 55446/69. Heading F3A. [Also in Division H1] A fuze for a hollow charge warhead of a rocket comprises a detonator 3; a detonator locking element 22 with an integral plunger 27; a fixed cylinder 26 containing granules (not shown); and a ring 30 which, under the effect of inertia on launching the rocket, moves helically down the cylinder 26 to align an orifice in the ring with an outlet 28 in the cylinder. Egress of the granules through the uncovered outlet 28 causes the locking element 22 to be retracted with delay. Members 32 on the cylinder engage a helical slot 33 in the ring so as to cause the helical movement. The ring 30 is also formed with an inertia flywheel 34 and is held against rotation by studs 40, 41 until a sleeve 38 carrying the studs sets back against the action of a spring 39 owing to its inertia. The sleeve is held in the fully retracted position by locking means (not shown). However, if the acceleration is not sufficient to retract the sleeve fully it is returned, together with the ring 30, to its original position by the spring 39, and the cam action of the pins 40, 41 engaging inclined surfaces on the flywheel 34. The detonator is an electrical detonator and is carried in a spring- driven slide 11. It is normally short circuited, but on moving to the armed position is connected through contacts (19, 24, Fig. 7, not shown) with a piezo-electrical crystal (4, Fig. 1, not shown) in the nose of the warhead.
