Title: High density sintered ceramics
Inventor: STEELE BERNARD ROBERT
IPC: C01F3/00
Filed: 1964-03-19
Abstract: Beryllium oxide of fine particle size e.g. of surface area 10-20 sq. m/g., is produced by evaporating by boiling an aqueous solution of beryllium sulphate to the point of crystallization and passing it immediately into a chilled and continuously cooled aqueous solution of an alcohol e.g. methanol or ethanol.  Crystals of the beryllium sulphate tetrahydrate are thus precipitated, which are separated and heated in vacuo to a temperature sufficient to drive off only two molecules of water of crystallization e.g. 100-200 DEG  C. for up to 12 hours to form the dihydrate, which is then calcined in air (e.g. at 900-1100 DEG  C.) to form the oxide.  Sintered bodies of the oxide of bulk density at least 2.85 g/cc., suitable as sheathing for fissile material of nuclear fuel elements, may be made by mixing the oxide powder with a binder, granulating the mixture and pressing to form green compacts which are then sintered in hydrogen.

Abstract: 1344515 Hold downs P C PEDDINGHAUS and W PEDDINGHAUS [trading as PAUL FERD PEDDINGHAUS] 28 April 1971 [14 May 1970] 11825/71 Heading B3W A hold down 4 is slidable between guides 9 and 10 into and out of a position in which it spreads out a bundle of rods 2 to be sheared into a single layer and clamps them against a surface 1 which has a cutting edge co-operating with a shear blade reciprocable in the direction of arrow 3. The path of the hold down is disposed at an angle of less than 45 degrees to the surface 1. A lever 16 pivoted to the shear frame at 17 has a roller 15 at one end engaging in a slot 14 in the hold down and is engageable at the other end with a roller 19 on an eccentric 20 to keep the hold down in raised position, Fig. 1. Rotation of the eccentric to move the roller to position 19<SP>1</SP> releases the lever and the hold down by its own weight, or urged also by a spring 22, slides down to engage the rods. The angle at which the longitudinal axis of the hold down is disposed relative to the surface 1 being less than 45 degrees stops the hold down being displaced by counter pressure of the rods during cutting. Further clockwise rotation of the eccentric brings the roller almost to the top dead centre position where it engages the lever again and as the roller returns to the full line position 19 of Fig. 1 it raises the hold down against the action of spring 22.

Title: New or improved method of washing raw wool
IPC: D01B3/10
Filed: 1951-05-22
Abstract: <PICT:0691648/III/1> A method of washing raw wool by means of a fluid hydrocarbon comprises circulating the fluid through the washing machine at a temperature between room temperature and the flash point of the washing agent, then through a closed heater, a closed rapid cooling device, a mechanical dirt extractor and back to the machine. The Figure shows a process in which the raw wool is inserted in a washing machine 1 and in which the pump 2 circulates the washing agent through a heater 3 which causes the fat and wax sludge in the used agent to dissolve.  The agent is maintained at the required temperature for a given period by thermostat 4 and is then rapidly cooled in unit 5, the dirt particles being mechanically separated from the washing agent in separator 6 and the agent is then passed back to the washer 1.  When the washing agent is continuously circulated, part is withdrawn from the separator 6, is further cooled in unit 8 and a further quantity of precipitated fats and waxes separated in unit 7 which may involve a centrifuging or distillation process.  The washing agent is cooled down so quickly in unit 5 that fats and waxes dissolved in it are not substantially precipitated during the mechanical cleaning in unit 6.  The separator 7 may be of the hermetically closed type having a shock-free feed and the unit 8 may cool the washing agent to a temperature of some 40-10 DEG C.  The separator 7 which removes from the washing agent the dirt previously extracted from the wool may comprise a centrifuge into which water or a water solution, such as common salt solution, is introduced into the centrifuge close to the nozzles arranged at its periphery so that there is formed at the periphery a layer of water through which the dirt particles pass on their way towards the discharging nozzles. Part of the dirt sludge thus discharged may be fed back into the centrifuge so that the percentage of dirt in the sludge discharge is increased.  In order to obtain the maximum de-oiling effect of the water or water solution its temperature may be raised to 50-70 DEG C, and surface tension reducing agents may be added to it.

The image is scanned, e.g. by television camera and the contrast of the image determined by measuring the brightness of each scanned image element in terms of its grey value according to a predetermined grey value scale, the frequency distribution of the grey values of the elements scanned being determined whereby for a contrasting image the grey values are unevenly distributed at the high and low ends of the grey value scale whilst for an out of focus image the grey values are more evenly distributed over the grey value scale. The frequency distribution of the grey values of the scanned elements are determined in terms of the number p(i) of the elements having a specified grey value i. As it is sought to determine when the grey values are unevenly distributed at the high and low ends of the grey value scale the numbers p(i) are weighted according to a weighting function w(i) having a large value for low and high values of grey value i and lower values for middle values of grey value i. The weighted frequency distribution numbers p(i) times w(i) are then either integrated over the grey value range or summed over the grey value range, the equation for said summation yeidling a value F of the degree of contrast is . the weighting value w(i) is calculated from the two formulae In apparatus using a television camera 3 viewing an image produced by microscope 1 the output of the television camera is analysed in terms of a sixteen level grey value scale by means 4, which grey value measurements are fed to a calculating means 5 whereby the statistical analysis according to the described method is performed. The value of F is then passed to a second calculating means 6 whereby the maximum value of F is sought, the degree of focus meanwhile being varied by means of a servomotor 7 operating a focus unit 8, the servomotor 7 being stopped when the desired maximum value of F is obtained. The television camera 3 may be replaced by a mosaic of light sensitive detectors, e.g. diodes Fig. 3, not shown.
