Abstract: The object of the invention is a method for enhancing the operation of a circulating mass reactor (1), which circulating mass reactor (1) comprises a fluidized-bed chamber (8) provided with a fluidized bed (108), means for separating fluidized material (80) from the flue gases, and a return conduit system (15, 16, 19) including at least one cooled return conduit (15, 16). In the method, for the combustion of fuel taking place in the circulation mass reactor (1) is provided a lower combustion chamber (89), which comprises a fluidized-bed chamber (8), and an upper combustion chamber (11) and a flow conduit (10) connecting them. The flow conduit (10), the means for separating the fluidized material (80) from the fuel gases and the return conduit system (15, 16, 19) are arranged to be located essentially between the lower combustion chamber (89) and the upper combustion chamber (11). The lower combustion chamber (89) and the upper combustion chamber (11) are dimensioned in such a way that the combustion of the fuel can be essentially completed before the discharge of the flue gases from the combustion chamber (11), whereupon the average delay time of the flue gases in the upper combustion chamber is most preferably 0.3-3.0 seconds. The fluidized material (80) is separated from the flue gases after the upper combustion chamber (11) and guided back to the fluidized-bed chamber (8) through cooled return conduits (15, 16) and an uncooled return conduit system (19) in the desired ratio.

[Also in Division B3] A grinding tool having the same surface configuration as a master is made by providing a blank comprising a number of arcuate sections arranged with adjacent faces in contact to form a wheel with a central axial bore which can be collapsed inwardly, fixing the sections rigidly together and cutting the desired master shape in the periphery of the blank. An annular mould ring is placed around the shaped periphery of the blank and a moulded band is formed therein. The blank is then collapsed inwardly and removed from the ring, the inside contoured surface of the ring is coated with abrasive particles, a hub is placed coaxially within the ring but not in contact with it and the space between the ring is filled with a hardening composition, which bonds to the hub and the abrasive layer. The ring is then removed leaving a grinding tool of the same shape as the original blank. As shown, the unshaped blank 20 comprises sections 28a, 28b, 28c, 32a and 32b which fit together to form a wheel with a central axial passage. Sections 32a and 32b can be moved inwardly to collapse the blank. The blank is maintained rigid by split rings 58, 60 inserted over flanges 66 and cylinder 50 with end flange 76 secured by screwed ring 82. The outer surface of the blank is profiled with grooves 104 and 114 as shown in Fig. 5 and the profiled blank is placed on a shaft 120. A mould ring 130 is placed on the shaft, defining with the contoured surface of the blank a mould cavity and this cavity is filled with a moulding composition which may be paper pulp, plastic or a rubber composition and is preferably loaded with a filler which renders it electrically conductive. When the moulding composition has set the blank and moulding are removed from the mould ring 130 and the blank is collapsed and removed from the moulded band 172 which is reinserted in the mould ring. A layer 190 of abrasive particles, preferably diamond, is then formed on the profiled surface of the band, a hub 200 is placed over shaft 120 and is positioned inside the band 172 and the area between this hub 200 and the abrasive layer 190 is filled with molten metal or an epoxy resin which bonds to the abrasive layer and the hub. The moulded wheel is then removed from the mould ring 130 and the moulded band 172 is removed leaving a grinding wheel of the same profile as the originally profiled blank. The grinding wheel is preferably used as a master for shaping other wheels to a complementary contour.

[Also in Divisions C3 and D2] A granular starch product which may be included in sizing and pigmented coating compositions for paper, is produced by treating bleached, oxidized or anionic starch with an aqueous alkaline solution (sodium, potassium, lithium or ammonium hydroxides) at a temperature below the solubilization temperature of the starch to obtain an aqueous alkaline starch slurry, acidifying the slurry and separating the starch from the slurry to recover the granular starch product. The aqueous alkaline starch slurry, at pH 10-12, is allowed to stand at a temperature of from 10 to 60C for a time of from a few seconds to 24 hours before being acidified, to pH 4.5-8, by sulphuric, hydrochloric, phosphoric or acetic acids. The starch is separated from the slurry by flash-drying, centrifugation or filtration and is washed with water to remove impurities. Paper sizing compositions comprise aqueous liquid and from 1 to 25%, based on total weights, of the granular starch product prepared from bleached or oxidized starch and subsequently solubilized. Paper coating compositions comprise aqueous liquid of 20-70% suspended solids content, including 15-60% of an inorganic pigment (clay, talc, titanium oxide, blanc fixe, powdered tin, precipitated chalk, satin white and ground limestone) and 5-30% of the granular starch product prepared from bleached or oxidized starch.

Abstract: 1289885 Lasers CANADA DEFENCE MINISTER OF 20 Aug 1970 [29 Aug 1969] 40232/70 Heading H1C In an atmospheric pressure gas laser pumped by a pulsed discharge transverse its optical axis, high voltage pulses are fed to the pumping electrodes and have an amplitude and duration such that the excitation ends before a bright arc is formed. The pumping discharge is therefore in the form of a number of fine discharge paths known as a shower, as distinct from a single arc. Electrode constructions are disclosed which are stated to cause uniform potential gradients in the gas and therefore to favour shower discharges. In Fig. 1, the electrodes are in the form of plates 14, 16 each carrying pins 13, 15. An electronic switch 18 connects the electrodes to a capacitor 17 of predetermined capacity and charge. The electrodes may also be circular, rectangular, L-shaped, arcuate or various combinations thereof, Figs. 2-11 (not shown). In Fig. 13, the pumping electrodes 57 are connected to a D.C. potential which charges capacitor 55 via a limiting resistor or inductor 58. When trigger 53 is closed, a first discharge occurs in the laser, and capacitor 56 is charged. A second discharge is obtained by closing trigger 54.
