Title: Improvements in or relating to methods of plating uranium with magnesium
Inventor: FLINT OLIVER
IPC: C23C10/34
Filed: 1962-03-28
Abstract: <PICT:0958717/C3/1> A film of magnesium is formed on uranium metal by heating a mixture of magensium metal and cupric bromide in the presence of the uranium metal.  The process is conducted under reduced pressure and in the substantial absence of free oxygen and water and to a temperature and for a time sufficient to permit the magnesium to deposit a film.  "Pyrex" (Registered Trade Mark) glass enclosure 1 contains the reaction mixture at 2, with uranium turnings at 3 to act as a getter after evacuation, 4 and 6 are spacers, and 5 represents the uranium article.  The reaction mixture is dried and the tube is then evacuated to, say, 10-4 mm. Hg. During evacuation furnace 10 surrounding article 5 is energized to heat the article to 500  DEG C. for 15 minutes to de-gas the specimen at elevated temperature.  After cooling the system is sealed off.  Mobile furnace 7 then heats the getter 3 to remove residual oxygen and remaining water.  Next after cooling the reaction mixture is transferred by tilting to cover the article 5 and the whole is heated at, say, 55 DEG C. for 5 hours.  The CuBr2+Mg mixture contains 5-30%, preferably 20%, by weight of the bromide and the mixture should be sufficient to cover completely the uranium article.  The pressure may range between 10-3 and 10-5 mm. Hg. and the reaction is conducted between 500-600 DEG C. for 3-10 hours. The water content of the reaction mass 2, either absorbed or combined should be reduced to below 0.12 by weight prior to evacuation and sealing.

Title: Improvements in infra-red apparatus for measuring distances
IPC: G01S13/91
Filed: 1955-04-27
Abstract: 801,871. Determining height of aircraft by radiation beams. BRINRO, Ltd. April 27, 1955 [May 6, 1954], No. 12192/55. Class 40 (3). The height of an aircraft is determined by projecting a modulated beam of infrared radiation from a source S to the ground and receiving the radiation on a receiver E sensitive to the modulation frequency. Either transmitter S or receiver E is then made movable about an axis perpendicular to the line joining them and the angular position of that element when the receiver receives the reflected rays is an indication of the height of the aircraft. Figure 2 shows an arrangement for modulating the light beam. The infra-red source 2 is indicated at one focus of an ellipsoidal mirror 3 and a motor - driven chopping disc 5 rotates in the other focal plane to which the infra-red rays are reflected. The modulated beam strikes convex mirror 6, is reflected on to parabolic mirror 7 and projected as a modulated beam of parallel rays. Fig. 3 shows the arrangement for scanning the field of view of the receiver and consists of a pair of coupled mirrors 8, 10, oscillated by a crank mechanism driven by motor 13. Radiation reflected from the ground is reflected from mirror 9 to mirror 10 and then on to the radiation sensitive device 8 which is fixed. Indicating system.-Motor 13 oscillating mirrors 9, 10 also rotates magnet 16 generating in coils 17 sinusoidal voltages which produce a linear sweep in cathode-ray tube 17. Signals produced in infra-red receiver cell 8 are applied to amplifier 20, 21 which include a filter 22 wired to the modulation frequency of the light incident on the cell. The output pulses produced by the cell as its scanning mirrors oscillate across the portion of the beam on the ground are arranged to make the trace visible so that the position of the pulse along the screen of the C.R.T. indicates the height of the aircraft.
