Abstract: 1,143,119. Cathode-ray tube displays. INTERNATIONAL BUSINESS MACHINES CORP 20 Oct., 1966 [29 Dec., 1965], No. 46894/66. Heading H4T. In a cathode-ray tube display arrangement binary coded signals representative of Alpha- Numeric &c. characters and produced by a keyboard 10 (Fig. 1) are converted to corresponding video signals by a composer 12 and to corresponding binary-doded-decimal (BCD) signals by a correcter 13, both sets of signals being stored in a cyclical delay line store 21 synchronously with the operation of the display tube 33, the former during time portions corresponding to vertical trace intervals and the latter during time portions corresponding to vertical re-trace intervals. The characters produced may then be verified visually by the operator and after any necessary correction the application of a (positive) pulse to read line 50 supplies the equivalent binary-coded-decimal signals to a load device 42 which may be a data processing system. The delay line 21 stores a complete field of video and BCD signals and in the display each character is allotted a matrix of 6 (wide) by 8 (high) charac - ter bits of which 5 by 7 are utilized for video production whilst the extra bits are employed for horizontal and vertical spacing giving a total of 8 lines each containing 18 characters (Figs. 2 to 7, not shown). In practice; the delay line comprises two delay line elements (Fig. 8, not shown) which receive the odd and even numbered bits respectively, the outputs being fed back to the inputs for recirculation until the feed-back path is interrupted by manually operated switch means when a new set of characters is to be entered into the system. The output of the timing control circuit 54 (described in detail in connection with Fig. 9, not shown) comprising horizontal and vertical synchronizing signals may be combined with video signals from the delay line and fed to the video amplifier of a conventional television receiver used as the display means.

An apparatus for handling eggs comprises two motor-driven endless chains 60 supporting between them rods 14, a pair of flanged rollers 16 rotatable and slidable on each of the rods 14 and an egg supporting coiled spring 20 located on each rod 14 between the rollers 16. Eggreceiving cavities are formed by means of large and small diameter coils 22, 24 of adjacent rows of the springs 20 which are of stainless steel and may be coated with rubber or plastic. The flanges of the rollers 16 are in engagement with guide surfaces 18 which cause the springs 20 to be compressed in an egg receiving area, whence the eggs have their long axis vertical, and to be expanded at an egg candling station 98 whence the eggs lay horizontally. At the candling station 98 the eggs are rotated with rotation of the springs 20 by means of flexible strips of webbing 118 contacting the underside of the larger spring coils 22. The webbing 118 on pressure plates 120 is reciprocated longitudinally of the egg conveyer by means of a lever system 122, 124, 128, 130, connected to a crank arm 74, driven by a motor 64. The crank arm 74 also drives an arm 72 which engages a ratchet-wheel 66 through a pawl 70. The wheel 66 drives a chain driving sprocket 62 step by step, and may have its drive interrupted by means of a manually-operated arm and lever 96, 94. A box 100 containing lights 102 is positioned beneath the egg conveyer at the candling station 98. The top of the box 100 has longitudinal slots 106 and may have adjustable light shields 104, 108. Light shields 114 above the eggs at the candling station are horizontally adjustable in guide members 110. In a further embodiment, Fig. 13, the conveyer system is used to carry eggs with their long axis vertical to a washing chamber 148 where washing liquid is sprayed on to the eggs from spray heads 150 and 152 and the eggs are cleaned by brushes 166. The eggs then pass into a drying chamber 168 containing electric heaters 170 and air blowers 172. At the end of the washing chamber and the start of the drying chamber the springs 20 are expanded by the guide plates, the eggs assume a horizontal position and are rotated via the springs 20 by an auxiliary endless belt 160. The auxiliary belt method of rotating the eggs may be employed in the candling operation and the egg carrying conveyer may have a continuous motion. The larger diameter coils 22 of the egg supporting means may be replaced by wooden, rubber or plastic spools (Fig. 7, not shown). The eggs are delivered to the conveyer either by a vacuum on mechanical lifting device 144 or by an egg moving bar transverse to and at one end of the conveyer (Fig. 2, not shown).

Filed: 1971-10-11
Abstract: 1405097 Cracking IMPERIAL CHEMICAL INDUSTRIES Ltd 28 Sept 1972 [11 Oct 1971] 47194/71 Heading C5E Naphthas rich in hydrocarbons of high octane number are produced by passing a hydrocarbon feedstock boiling above 70‹ C., together with hydrogen and steam, over a composite catalyst comprising a steam-stable, acidic, mixed-oxide composite and a metal of Groups 6A, 8 or 1B or rhenium or its oxide or sulphide. The partial pressure of hydrogen is at least one atmosphere and high enough to allow hydrocracking but not so high as to suppress the formation of aromatics; the quantity of steam is between 0À1 and 5 molecules per atom of carbon and enough, with the hydrogen to suppress the formation of by-product carbon; the overall pressure does not exceed 100 atmospheres, and the temperature is between 300‹ and 650‹ C. The process combines exothermic hydrocracking with endothermic catalytic reforming and steam reforming and can be close to thermal neutrality, and to hydrogen balance. Make-up hydrogen if needed, can be obtained by steam reforming. Suitable feeds are straight-run fractions and cycle oils from catalytic cracking, thermal cracking, visbreaking and coking, from light naphthas to heavy gasoils. Gaseous hydrocarbons up to butanes and diluents such as CO 2  may be present. Compounds of sulphur or nitrogen, e.g. H 2 S or NH 3 , may be added to modify the catalyst. The feed maybe first hydrofined. Highboiling products of the cracking may be recycled to extinction. Oxide composites referred to are silica-alumina, silica-zirconia, silica-magnesia, alumina-magnesia, alumina-titania, and silica-alumina-zirconia. They may be modified by treatment with aqueous acids, alkalies, solutions of alkaline earths, halogens or halides, steam or water. Suitable metals are Cr, Mo, W, Co and Ni separately or in combination; Ru, Rh, Pd, Os, Ir and Pt separately, in combination with one another, or in combination with Ag, Au, Re, Cu, Zn, Cd, Ge, Sn, Pb, As, S or P.

Title: Method of making cesium compounds of high purity
Inventor: MOOLENAAR ROBERT JOHN
IPC: C01D17/00
Filed: 1963-12-02
Abstract: Pollucite, a cesium aluminium ore, is heated in an inert gas atmosphere with an alkali metal reductant, e.g. Li, Na or K, at a temperature above the vaporization temperature of cesium metal, but below that of the reductant employed, to distil off cesium metal. The cesium is redistilled then intermixed with mercury, e.g. in excess, in a glass or polyethylene vessel under an inert gas atmosphere for 1-3 mins. at 20-70 DEG  C., to form cesium amalgam. The amalgam is hydrolysed with pure water to give cesium hydroxide, which may be reacted with acids to give cesium salts. The presence of bars or rods of carbon or graphite in contact with both the amalgam and water facilitate the hydrolysis.  Using sodium as the reductant the temperature employed at atmospheric pressure is between 680 DEG and 850 DEG  C. in an inert atmos. blanket, e.g. argon, helium, neon, krypton, xenon, radon.  The cesium is fractionally redistilled at a boiler temperature of between 300 DEG  and 740 DEG  C., at a distillation column top temperature of between 335 DEG  and 400 DEG C. at the beginning of the step which rises to between 430 DEG  and 450 DEG  C. during distillation, and at a column top pressure of between 5 and 50 mms. of mercury absolute.  Cesium carbonate may be prepared by passing CO2 gas through an aqueous solution of cesium hydroxide.  Other acids may be hydrofluoric, hydroiodic, hydrobromic, hydrochloric, nitric, sulphuric, phosphoric, and salt forming carboxylic acids.
