Title: Process for producing uranium tetrachloride
IPC: B01J19/28
Filed: 1945-02-16
Abstract: Uranium tetrachloride is produced by advancing finely-divided uranium dioxide through an elongated reaction chamber heated to 440 DEG  to 475 DEG  C. and contacting the advancing oxide with a countercurrent stream of carbon tetrachloride vapour.  As shown in the drawing (Fig. 1), an inclined rotatable reactor 38 is associated by gas-tight glands 47 and 48 with static end-pieces 26 and 27.  A heating muff 86 is provided around the central portion of the reactor 38 and uranium dioxide reactant is fed from a reservoir 67 through a screw conveyer 71 into the upper end of the reactor.  Carbon tetrachloride passes from a reservoir 21 to a vaporizing vessel 8 and the vapours pass through line 23 to the lower end of the reactor.  Uranium tetrachloride reaction product falls through a pipe 106 to a reservoir 109 whilst excess vapours pass through line 113 through <PICT:0812792/III/1> <PICT:0812792/III/2> <PICT:0812792/III/3> a condenser tube 119; the latter condenses excess carbon tetrachloride which passes through a line 127 to a tetrachloride reservoir 128. Carbon dioxide may be passed through line 112 into the uranium tetrachloride receiver 109 to maintain an inert atmosphere therein. The reaction vessel is provided with an internal glass liner 57 and, to provide additional agitation and maintain the wall of the liner free from deposits, a spring-loaded longitudinal scraper member 76 of arcuate cross section is provided (see Fig. 3).  The scraper member is supported on a bar 79 running longitudinally of the reaction chamber.  As shown in Fig. 2, which is an enlargement of the right-hand side of Fig. 1, the uranium dioxide reactant is fed through a conveyer 71, well into the glass lining of the reactor 57. The latter extends beyond the reactor casing 38 inside a coaxial static tube 34 attached to the end-plate 26.  The gas-tight joint is effected by packings 51 and 58.  Similarly at the other end of the reactor the carbon tetrachloride feed-pipe extends well into the reactor to minimize contact of such vapours with the packing members. Specification 812,121 is referred to.

Title: Multi-channel radio communication system
IPC: H04J3/00
Filed: 1951-02-20
Abstract: 686,580. Radio signalling. BENDIX AVIATION CORPORATION. Feb. 20, 1951 [March 17, 1950], No. 4143/51. Class 40 (v). In a radio communication system having a plurality of channels, each comprising a transmitter and receiver tuned to the same frequency, the channels are sequentially keyed on at a frequency higher than the highest modulation frequency to prevent cross-talk therebetween. In the three-channel embodiment described, a 10 kc/s. blocking oscillator 1 triggers a chain of flip-flop multivibrators 2 ... 6. Pulses from circuits 2, 4, 6 are passed to pairs of transmitter and receiver gate circuits 7, 8; 9, 10 and 11, 12 for the three channels respectively. When relay RE3 is energized, these gate circuits control their respective transmitters and receivers, which are connected to contacts h, k, n, q, t, w, through the contacts g, j, m, p, s, v, respectively, the transmitters and receivers being arranged for normal operation when relay RE3 is unenergized. The gating arrangements come into operation by the energization of relay RE1 when any transmitter is operated, to close contacts a, b. This feeds 25-microsecond pulses from circuit 6 to the grid of valve V1, and thereby causes the valve to pass a large enough mean anode current to operate relay RE3 connected in its anode circuit. To provide a visual indication of a fault in the distributer circuit pulses from circuit 6 are fed continuously to valve V2. This valve normally therefore maintains relay RE2 energized to light a green indicator lamp 12 but failure of the distributer substitutes the red lamp I1. At the same time, relay RE3 releases to restore the transmitters and receivers to continuous operation. Details of circuits 1, 2, 3, 7, 8 are given, Fig. 2 (not shown). In a modification, Fig. 4 (not shown), the relay RE3 is energized directly when any transmitter is used, the other control and indicating circuits being omitted.

Title: A system for the accurate determination of the transmission times of electro-magnetic waves
IPC: G01S11/08
Filed: 1963-02-01
Abstract: 1,031,012. Radio position finding. TELEFUNKEN PATENTVEBWERTUNGSGESELLSHAFT m.b.H. Feb. 1, 1963 [Feb. 7, 1962], No. 4208/63. Heading H4D. In a position finding system of the type wherein the position of an object F 1  is found from the propagation times of radio signals between the object and at least three known positions, and timing standards are used at the object and at the known positions, a transmitting station S 1  and a timing standard ZN 1 , of insufficient accuracy for the required accuracy of measurement, is provided at the object, a receiving station E 1 /E 3  and a timing standard ZN 3 /ZN 5  of sufficient accuracy, is provided at each of the known positions, and the propagation time error. #t, produced in the measured propagation times I I /I III , by the inaccuracy of the transmitter timing standard ZN 1 , is calculated in a co-ordinate computor system (not shown), taking into account the measured propagation times the known positions of the receiving stations and the length of the object, and deducted from the measured propagation times. The system is described as incorporated in a system displaying the positions of aircraft (which are the above mentioned " objects " as luminous spots f 1 , f 2  on a C.R.T. display L, the C.R.T. having a television type raster and being fed with digital information from a computer R giving the line on which a position spot is to be displayed and the distance along that line, of the position spot f 1 . The computer R is fed with the corrected propagation times or the equivalent distances. For n aircraft the signals are transmitted from each aircraft in succession at 10 m/sec. intervals. The whole procedure is repeated every 10 seconds. The position of each aircraft may be shown at successive times, to give an indication of its speed and course. The timing standards ZN 3 /ZN 5  may be in the form of atomic clocks or may be in the form of less accurate quartz clocks which are periodically synchronized with a more accurate clock at a control station. However, as long as the errors in the quartz clocks relative to each other are not too great the clock at the control station need not be highly accurate. Radio links may be used between the control station and the receiver stations. The aircraft may transmit information coded signals, for example the aircraft's height, and the decoded information may be stored. If more than 1000 aircraft are to be detected within the period of 10 seconds, then some of the aircraft may be allocated to a different frequency. The system may be reversed, the receiving stations now transmitting and the aircraft receiving the signals and computing its position. The less accurate clock is still kept in the aircraft. More than three receiving stations, or transmitting stations in the reversed system, may be used, the computer selecting the three with the shortest propagation times.

Abstract: 590,717. Driving milling &c. machines ; spindles. DEFIANCE MACHINE WORKS, Inc. Feb. 21, 1945, No. 4330. Convention date, April 8, 1944. [Class 83 (iii)] In a machine tool such as a milling machine, a hollow tool spindle is rotatable at a high speed on a stationary axle and has a large mass concentrated near the cutter to give a fly-wheel effect. In one form, the spindle consists of a sleeve 35, Fig. II, adapted to receive a cutter at the end 37 and mounted by means of ball bearings 44, 58 and a roller bearing 45 on an axle 41 adjustable in the machine frame. The bearings 44, 45 are spaced by a sleeve 48 and the inner races are secured by a clamping washer 46 and nut 47 on the axle, whilst the bearing 58 is pre-stressed by a cover-plate 57 screwing in the end of the sleeve 35 and locked by set-screws 59. The sleeve is driven by a built-in electric motor consisting of a rotor 51 secured thereto and a field stator 52 attached to the axle 41 and supplied by cables 54 passing through the axle. In a modified construction, the sleeve 35 is of uniform maximum diameter throughout, the axle is shorter and the. intermediate bearing 44 is dispensed with. In another modification, the axle 41, Fig. V, is shorter still and the motor has a radially arranged rotor 95 and stator 97 to form a large diameter sleeve 96 with a considerable fly-wheel effect. In a further modification, the sleeve is shaped as shown in Fig. II, and is driven by a conventional type motor whose shaft passes through the centre of the axle and is connected to the cutter-end of the sleeve by means of a yielding coupling. The motor may then be disposed remote from the sleeve and its shaft is supported within the axle by spaced bearings. The invention is described as applied to a milling machine having a vertical and two horizontal adjustable spindles, the work being carried by a horizontal universally adjustable table. The electric motor may be replaced by a hydraulic or pneumatic turbine. Cutter arbors and mountings.-The cutter mounted on the end 37 of the sleeve 35, Fig. II, is driven by two dogs 38 attached to the sleeve by screws 67, a face milling cutter being secured by screws inserted in tapped holes 39 or a shell cutter by a single screw in a central hole 40 of a spigot 36 on the sleeve. Lubricating machines.-The bearings 44, 45, 58, Fig. II, for the cutter sleeve 35 are lubricated by an oil mist carried by air supplied by a pipe 61 passing through the stationary axle 41 and leading to a nozzle 62. The oil-laden air filters through the bearings and escapes through a clearance 41<1> between the end cap 57 of the sleeve and the axle 41.
