Title: A device operating as an altimeter and an altitude stabilizer
Inventor: GILLY LOUIS
IPC: G05D1/04
Filed: 1968-03-12
Abstract: 1,214,906. 906. Automatic altitude control. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 12, 1968 [March 23, 1967], No.12083/68. Heading G3R. [Also in Divisions G1, G6 and H1] Apparatus for measurement and control of the altitude of an aircraft comprises first and second radiation sources and a radiation detector to detect the pressure of the atmospheric air, the detector being used in association with the first source when measurements of altitude are to be carried out, and with the second source when the output of the detector is to be used to control the altitude, the detector circuitry including a gate through which the detector output can be coupled to a servo mechanism, operating on the elevator or engine of the aircraft, when control of the altitude is to be undertaken. The radiation manometer comprises a chamber 1, through which atmospheric air can flow, containing a surface barrier diode of N-type silicon 2 mounted on a vertically displaceable arm 5. The two radiation sources are α-emitters, one 3 being of Am241, formed as an electrolytic deposit on a platinum disc, and the other 4 being a relatively thick disc of enriched uranium. They are mounted on a rotatable table which turns between two positions bringing either one of the sources in line with the detector 2. When source 3, which is effectively a monochromatic source, is operative the output of device 9, an integrator or ratemeter, operating on pulses from the detector which have passed through pre-amplifier 7 and threshold amplifier 8, is connected through gate 11 to operate a servo mechanism 12 controlling the aircraft elevator or engine, whereby a constant altitude may be maintained. When source 4, emitting a much wider range of energies, is operative the gate is closed, and the apparatus may function as an altimeter, the indicator 10 being graduated in altitudes. In altitude measurement, to obtain maximum sensitivity the threshold level of amplifier 8 is set as low as possible, by control C 3 , but high enough to suppress noise pulses. The sensitivity of the apparatus is affected by variation of the sourcedetector distance and several scales are provided on meter 10 corresponding to particular values of this distance. In altitude control, the threshold level is set to define the altitude to be kept. This is possible since, with the americium source, the pulse count rate is affected greatly by very slight altitude  changes, up to a certain height, Fig.6 (not shown). The effective source-detector distance is adjusted when controlling altitude, for different altitude ranges by the introduction of respective filters for each range e.g. of polyester film or polyester film plus a gold filter. The apparatus is calibrated in a standard atmosphere and so corrections to the measured altitude are necessary to allow for air temperature variations with altitude.

Patent GB-1015301-A (GB)
Title: Improvements in or relating to the manufacture of nuclear fuel
IPC: G21C3/62
Filed: 1963-03-27
Abstract: Spheroid nuclear fuel carbides are formed by heating particles comprising nuclear fuel metal and carbon in an oxygen-free atmosphere to a temperature sufficient to melt and spheroidize the particles, and then cooling them to form nuclear fuel carbide spheroids.  The particles are preferably a mixture of a fuel metal oxide, carbon, and a carbonizable binder such as ethyl cellulose, polyvinyl alcohol, shellac, polymethylmethacrylate, polystyrene, furfural alcohol resin, or paraffin.  Alternatively, the fuel may already be a carbide, in which case no particulate free carbon is added to the initial mixture.  The fuel may be uranium, thorium or plutonium, and mixtures thereof, enriched or unenriched.  The described method will frequently impart a thin carbon layer to the carbide spheroids. Particle preparation.-The fuel, carbon and binder, all in the form of fine particles, are mixed dry, and a suitable volatilizable binder solvent such as trichlorethylene slowly added to the mix to form a slurry; agitation is continued until the solvent has volatilized, leaving particles 300-500 micron in diameter.  They are then oven dried at 60 DEG  C. and sieved to give a particle size of 295 to 495 microns, i.e. about 75 microns larger than the ultimate carbide spheroids required.  The particles are then dispersed in sufficient graphite flour to ensure their physical separation (1 part of graphite to 8 of particle, by weight).  Spheroidizing.-The particle-graphite mixture is placed in a vacuum and induction heated to the carburizing temperature of about 2,000 DEG  C.  After carburizing has been completed, this stage being marked by a drop in vacuum pressure due to a cessation in gases from the carburizing reaction, the temperature is increased to at least 50 DEG  C. in excess of the highest melting constituent present in the particles. (The carburizing is of course dispensed with if the fuel is already in carbide form.)  Since each particle is separately suspended in the graphite flour, dense spheroids are formed on re-freezing.  Cooling may be accelerated by passing methane or some other hydro-carbon gas through the reaction zone which results in the presence of a thin coating of adherent graphite on the spheroids.  Spheroid processing.-After the cooled spheroids have been separated from the graphite and sized by sieving, they may be used as such as a nuclear fuel, or they may be further coated with pyrolitic carbon.

Title: Apparatus and method for performing sheeting or coating operations by rolling or calendering
IPC: B29C43/24
Filed: 1952-05-20
Abstract: 723,041. Coating webs. TRIGGS, W. W. (Wingfoot Corporation). May 20, 1952, No. 12711/52. Class 140. [Also in Group V] In roller sheeting machines, to allow for deflection of the rollers due to the pressure of the material, apparatus according to the invention comprises a pair of rollers forming a roll bight between which material can pass, the opposite ends of at least one roller being supported in encompassing bearings part of one of which at least serves as a fulcrum and in which means are provided for applying a controllable pressure to some other part of the bearing or bearings so that the axis of the roller can be controllably cambered at will. Fig. 1 illustrates diagrammatically a three-high set of rollers in which the bottom pair or finishing rollers 3, 4 can be adjusted to bend or camber towards one another. The roller 3 is journalled in bearings 11, 13 and is extended in both directions to enter outboard bearings 12, 14. The roller 4 is similarly carried by inner bearings 17, 18 and outboard bearings 19, 20. A hydraulic jack 27 is positioned between the outboard bearings 12 and 19 and a hydraulic jack 28 between the bearings 14 and 20, and when these jacks are operated the outboard bearings at each end are forced apart and the rollers are cambered so that their centres approach, as shown in exaggerated form. For sheeting plastics the rollers are not truly cylindrical but crowned, as shown at 58, 59, Fig. 4, but the degree of crowning is only slight, so that when a plastic sheet is rolled between them the surfaces of the rolls will move further apart, to the positions 60, 61. Compensation is applied by cambering the rollers as in Fig. 1, resulting in their surfaces being parallel, as indicated at 62, 63. The distance between the rollers 3 and 4 may be made adjustable by mounting the bearings 17, 18 so that they are slidable vertically and arranging screws 25, 26 to engage them. When these screws are tightened the rollers are moved together, and when they are loosened the roller 4, by its weight, moves away from the roller 3. Similar means for adjusting the distance between the rollers 2, 3 may be provided by making the bearings 7, 8 for the shaft 2 vertically slidable and engaging them by screws 21, 22, the roller 2 being caused to move away from the roller 3, when the screws are slackened, by springs 23, 24 between the bearings. Inversions of the arrangement shown in Fig. 1 are described. In one, the rollers are cambered away from (instead of towards) one another by forcing the outboard bearings together, a hydraulic jack then being required on the outside of each. In another inversion the main bearings, supported by the frame, are outboard and the bearings subjected to the pressure are inboard, the roller then being cambered downwards when pressure is extended downwards and vice versa. A more detailed description of the arrangement diagrammatically shown in Fig. 1 is given.
