Abstract: 220,842. Barker, R. W., (American Bank Note Co.). Oct. 10, 1923. Set-off, preventing.-In means for collecting in a pile printed sheets, which have been rolled up in a web in order to keep them damp, the material of the web itself is used to prevent dropping of the sheets as the web is unwound, and to convey them to a stripper by which they are deposited on a collecting shelf. The web containing the sheets passes from a supply-roll 19 over a guide-roller 17 of small diameter, and then beneath the supply-roll itself, and over guide-rollers 23, 24, 25, to a winding-roll 22. As the web passes over the roller 17 the sheets are tripped off by stripperfingers 28, and delivered to a shelf 12. The passage of the web beneath the supply-roll tends to prevent the sheets from leaving the roll, and carries a separated sheet upwards so that it may be placed by hand on the shelf 12. A weighted roller 31 bearing upon the winding-roll 22 is guided in slots having an offset portion 32, for sup. porting the roller out of contact with the winding- roll.

Abstract: 1,152,866. Coating apparatus. MONSANTO CHEMICALS Ltd. 12 April, 1967 [7 June, 1966], No. 25337/66. Heading B2L. [Also in Division B5] Apparatus for coating a pattern with slurry and treating the slurry with a gas or vapour to form an investment mould, comprises a box or cage with an opening through which the pattern can pass, and mounting means for the pattern, so that the pattern rests inside the box when the opening is uppermost and hangs outside when the box is inverted. The pattern is coated with slurry while outside the box and treated with gas while resting inside. As shown the pattern 3 is mounted in the box 4. by a "L" shaped arm 5 attached to bar 9 in releasable bearings 10. The arm 5 has a rotatable coupling 110 (not shown) which rests on a stop 11. Channels 12, 13 on the base of the box cooperate with arms or pivoted bar 17 by which means the box is swung into an inverted position adjacent the ends of bars 20, 21. The bar is pushed by a ram (not shown) onto these bars, and the pattern which is hanging down as the box has been inverted is immersed in the slurry bath 23. As the boxes move along rods 20, 21 in the direction shown by arrow (b), the coupling 110 on "L"-shaped arm 5 runs along rail 24 and rotates the pattern. The coupling is frustoconical and the speed of rotation is varied by varying distances of the rail 24 from the pivot 10. The pattern is lifted from the slurry by a rise in rail 24 and is then passed through bath 28 containing a fluidised bed of stucco which further coats the pattern. At the end of the coating stage the box engages arms 29, 30 on pivoted rod 31 and is transferred to rods 32, 33, the pattern re-entering the box during rotation of the pivoted arm. The boxes enter tunnel 34 through a seal and are treated with gas or vapour which enters at 35 and is exhausted through 36 and 37. At the end of the cycle, the pattern may be recycled, and is removed when a sufficiently thick coating has built up. The releasable bearings 10 are preferably formed so that the pattern and arm 5 can be lifted out when the box opening is uppermost, and can only rotate when the box is tilted.

In operation the anode 114 is earthed and -250 V is applied to the start cathode 108 to generate a glow discharge which is sequentially transferred along the cathodes by the sequential application of -250 V to each of the lines 134, 136 and 138 whilst the other two are maintained at -150 V. The glow discharge provides a source of electrons, and ions are prevented from bombarding the screen by inclining the anode strips 114 as illustrated. When a particular cathode is energized, selected electrodes 118 are also energized so that electrons impinge on display points corresponding to the intersection of the cathode with the selected electrodes. The selected electrodes 118 may be energized with a constant voltage of 6-10 volts for an alphanumeric display, or with a variable analogue or digital voltage to provide a grey scale. For a colour display the groups of cathodes connected to lines 134-138 may correspond to three different colours, the luminescent screen then comprising strips of different colour phosphors.

Abstract: 706,967. Preparing coal. UNION CARBIDE & CARBON CORPORATION. Oct. 10, 1952 [Nov. 14, 1951], No. 25415/52. Class 50 In preparing comminuted coal for hydrogenation or other processes for the recovery of chemical products, the material is rapidly heated to 200‹-500‹ C. without impairing its chemical or physical properties by mixing it with an inert gas at 400‹-1200‹ C. and so adjusting the heating period in relation to the particle size distribution of the coal as to heat all the coal uniformly before softening or coking of the finer particles occurs. As the temperature of the finer particles approaches the falling temperature of the gas more rapidly than that of the coarser grains a stage ensues in which the finer particles are cooling as the coarser are rising in temperature, and correlation of temperatures and distribution of particle sizes enables all the coal to reach the final temperature before the fine particles soften. Crushed coal is delivered to a pulverizer 3 over a screen 2 separating particles of up to 2 mm. diameter which join the pulverized material in a stream A of hot drygas raising the temperature of the particles to about 125 C. From a separator 4 the coal after removal of particles over 2 mm. collects in a bin 5 whence it is fed into a heating gas stream B at about 600‹ C. and discharged for further processing from a separator 9. Part of the drying gas from stream A circulating by a pump 8 is withdrawn through a separator 7, and some of the coal- and water-free gas is supplied to heater 11 through which the heating gas stream B is fed by a pump 10. A branch supply C from circuit B is added to the drying gas stream A. The coal temperature is preferably about 100‹ C. before the heating gas is encountered. This may be a mixture of nitrogen, water vapour, and carbon dioxide. The heating period which should not exceed a minute is preferably 1/ 10  to 10 seconds.
