Title: Process for coating powder reactor fuels with carbon
IPC: B01J2/00
Filed: 1962-11-27
Abstract: Powder reactor fuels, e.g. mixed crystals of powdered UC-ThC or UC2-ThC2, are coated with carbon in a reaction space by subjecting the fuels, held suspended in a fluidized bed, to the action of a hydrocarbon gas, e.g. methane, <PICT:1017089/C6-C7/1> using at least one pipe through which the fluidizing medium is passed, at a temperature (e.g. 1400-2200  DEG C.) sufficient to liberate carbon by decomposition, the gas being admixed with a carrier gas, e.g. argon, so as to maintain the temperature inside the pipe below the decomposition temperature of the hydrocarbon gas. The pipe may be cooled conventionally.  The coating may be carried out in the apparatus shown in the Figure wherein the ring pipe assembly 4 consisting of a pipe 5, a ring 6 and a cap 7, made of high-melting metal, e.g. tantalum, is arranged at the inlet of the reaction space 1 surrounded by a graphite casing 2, the pipe 5 being connected to an inlet tube 8 for the hydrocarbon gas K and the ring 6 being connected to an inlet tube 9 for the carrier gas T so that the carrier gas flowing through the annular gap 10 cools the pipe 5.  The tube 9 may also be surrounded concentrically by water cooling tubes, 12, 13, the casing being surrounded by a heating element 14.ALSO:Powder reactor fuels, e.g. mixed crystals of powdered UC-ThC or UC2ThC2, are coated with carbon in a reaction space by subjecting the fuelds, held suspended in a fluidized bed, to the action of a hydrocarbon gas, e.g. methane, using at least one pipe through which the fluidizing medium is passed, at a temperature (e.g. 1400-2200 DEG  C.) sufficient to liberate carbon by decomposition, the gas being mixed with a carrier gas, e.g. argon, so as to maintain the temperature inside the pipe below the decomposition temperature of the hydrocarbon gas.

Title: Improvements in and relating to recovery of halohydrins
Filed: 1961-12-27
Abstract: Halohydrins having up to 4 carbon atoms per molecule are extracted from aqueous solution by contacting with a water insoluble carboxylic acid or anhydride having at least 4 carbon atoms per molecule, to form a solution of the halohydrin therein, and separating the acid from the aqueous phase.  The acid employed may be preferably a mono-carboxylic acid of molecular weight of at least 116, or an aliphatic carboxylic acid, or may be a C4 to C20 acid, optionally halogen substituted, being less than 2% by weight at 20 DEG C. or preferably less than 0.5% at 20 DEG C. water soluble and includes linoleic, ricinoleic acids, or mixtures of acids obtained by the hydrolysis of naturally occurring glycerides, or tall oil or tall oil fatty acids.  A list of acids which includes specific representatives is given.  The acid has preferably an atmospheric boiling point 20 DEG C. higher or lower than the halohydrin.  The aqueous solution may in addition to the halohydrin contain hydrochloric acid, halides or sulphates of alkali or alkaline earth metals.  The process may be effected in a continuous countercurrent mode, the carboxylic acid containing the halohydrin being separated and recovered from the halohydrin for reuse by distillation or by steam distillation.  The apparatus which may be used for the continuous process can be a tower, to which the extractant is fed in at the base and aqueous halohydrin near the top.  The examples illustrate batchwise and continuous processes of glycerol dichlorohydrin recovery and show the effect of salt concentration on partition co-efficients.  The invention may be employed for recovering ethylene chlorohydrin, bromohydrin, iodohydrin, 1-ry and 2-ry propylene chlorohydrin, bromohydrin, iodohydrin; other halohydrins are specified.  The extraction is carried out at a temperature at which the acid is a liquid, e.g. 70-71 DEG C. using stearic; higher temperatures may also be employed if necessary by effecting the contact of the phases under pressure in excess of atmospheric.

Filed: 1972-10-06
Abstract: 1405953 Comparing diffraction patterns from dimensions; measuring dimensions photo-electrically WESTERN ELECTRIC CO Inc 6 Oct 1972 [8 Oct 1971 46202/72 Heading G1A and G1M A filament or wire 10, Fig. 1, which may be stationary or drawn through a die 13 passes through substantially coherent radiation (laser or mercury vapour lamp) from a source 17 and beamsplitters 19, 23 so that a diffraction pattern is produced at 20a at the focal point of a lens 24. A portion 18a of the split beam impinges upon a reference or master wire 22 and produces a diffraction pattern 20b for comparison with the pattern 20a. By carefully adjusting mirrors 21, 27 and lens 24 the two patterns are formed slightly off the optical axis of 24 and are displayed side by side, and the distances of wires 10 and 22 from the lens are the same which simplifies calibration. Apart from optical sources, diffraction patterns can be produced by electron beams, and Fresnel patterns used instead of Frannhofer patterns. In Fig. 2 the patterns are not displayed on a screen but are imaged by the lens 31 of a television camera 32 arranged such that the horizintal scanning lines thereof are parallel to the images of the patterns so that one or more of the scanning lines sweep across the image of the patterns. In Fig. 3 the patterns a and b are identical, indicating that the wire is of correct diameter and so then are waveforms c and d representing the video output of scanning lines. If waveform d is inverted and added to c then waveform e will be zero. If the wire diameters and the resulting waveforms are not the same however then the net result will not be zero and a pulse proportional to the pattern difference will be generated and may be measured. Such a measuring means, Fig. 5, comprises an analyzing circuit as in Fig. 2 which has AND gates 41, 42 both receiving on one input thereof the amplified video signal from circuit 36 which contains scanning lines representative of the two patterns. A clock 43 generates a pulse which is fed via unequal time delay circuits 44, 46 to the AND gates which feed via a third delay circuit 47 and an inverter 49 to an adder 48 the output of which is fed to an analog-to-digital converter 5 1 and a display device 52.

Abstract: 1367773 Vibration measurement GENERAL ELECTRIC CO 6 Oct 1971 [30 Oct 1970] 46454/71 Heading H4D Damage to a rolling element in a pair of engaging rolling elements, which damage produces a periodic vibration component (Fig. 3) having a peak amplitude above the amplitude of other vibration components, is detected by determining the value of the peak output of a vibration sensor and an average value of the sensor output, determining the ratio of the two values, and indicating when the ratio reaches a predetermined value. In the Fig. 2 system for checking ball bearing races 1 the amplitude of peaks 75 (Fig. 3) in the band-pass filtered and amplified output of vibration sensor 15 is detected at 18, the RMS amplitude of the filtered and amplified output of the sensor is detected at 20, and the peak to RMS ratio is derived in divider 21. The quotient signal is smoothed (in network 22, having a time constant much longer than the bearing rotation period) to remove spurious noise spikes and is applied to meter relay 23 which actuates audible or visual alarm 24 if a pre-set quotient signal level is exceeded. In the Fig. 4 modification for checking a particular gear in a gear train, the vibration signal from that gear is enhanced relative to other vibration signals by obtaining an average of the amplitude versus time wavetrains produced in several rotations of the gear. In each rotation a respective sync. pulse derived from tachometer 96 via frequency converter 97 (which allows for the gear ratio) triggers analyser 95 which then stores the values of successive amplitude samples of the wavetrain. The values from one rotation are added to corresponding values from preceding rotations to obtain an averaged wave-train which is then applied to peak and RMS detectors as in the Fig. 2 system.

As shown in Fig. 1, liquid cyclohexane is supplied at 5 to a reactor 1 containing bubble-cap trays, and air is supplied at 6. The mixture of oxidation products and unreacted cyclohexane passes to a reboiler 3 in which a part of the cyclohexane is evaporated and caused to pass up the reactor with the air supplied at 6.  The vapours leaving the reactor pass through a condenser 9 to a separator 10, from which cyclohexane is returned to the reactor by a pipe 11.  Oxidation products leave the apparatus at 15, condensed water is discharged at 12, and residual gases and vapours are withdrawn at 15.  Fig. 2 shows an apparatus in which the process is effected in a series of three autoclaves. Cyclohexane supplied at 23 flows successively through the autoclaves 22, 21, 20, and the liquid mixture of oxidation products and unreacted cyclohexane passes to a reboiler 35.  Air is supplied by a pipe 26 and passes successively through the autoclaves 20, 21, 22, together with cyclohexane vapour from the reboiler.  The vapours leaving the autoclave 22 are passed via a condenser 30 to a separator 24 from which the condensed cyclohexane is returned to the autoclave 22 by a pipe 25.  The oxidation products leave the apparatus at 38.  Examples of the operation of the appratus of Fig. 1 are given.  Small proportions of a catalyst, e.g. cobalt naphthenate, and (or) an initiator, e.g. cyclohexanone, may be added to the cyclohexane feed.
