IPC: B01D1/28
Filed: 1919-09-03
Abstract: 154,355. Marks, E. C. R., (Aktiebolaget Indunstare). Sept. 3, 1919. Vapours, utilizing, for effecting further evapora. tion; film evaporators.-Sulphite lyes and similar liquids are concentrated by evaporation in successive stages under the same temperature and pressure in evaporators in which the liquid is circulated in films and which are heated by the generated vapours after they have been compressed. The evaporator is of the kind described in Specifications 12462/11 and 22670/11, and comprises vertical externally-heated tubes c on the interior of which the liquid is distributed in films by devices c<1>. The vapours collect in a chamber below the tubes c and are forced by a compressor i into the heating-chamber g containing the tubes c. Baffles are fitted in the heating-chamber g. The evaporator is divided by partitions d<2>, e<2> into two compartments a, a' and b, b<1> in which the liquid is circulated by separate pumps m, m<1>. As the rate of evaporation is higher at low viscosities, a saving of heating-surface is effected by partially concentrating the liquid in the compartment a, a<1> before it passes, through a pipe k, to the compartment b, b<1> in which the concentration is completed.

Abstract: 875,779. Coating webs. AGFA A.G. June 24, 1959 [June 28, 1958], No. 21706/59. Class 140. In a brush coating machine having one or more oscillating brushes which are either each driven individually by a separate mechanism or together in combination by a common mechanism, the mechanism or mechanisms are mounted on one or more balancing masses each of which is suspended either resiliently or in the manner of a pendulum and adapted to oscillate  relative to the machine frame. As shown (Fig. 1) a brush 2 mounted in a machine frame 1 makes oscillatory movements in the X direction. The drive is external (not shown) and the crank mechanism consists of a crank 4 and connecting rod 5 mounted in a balancing mass 3, which is suspended in the manner of a pendulum. The centres of gravity of the brush and of the balancing mass are at the same height. If the weight of the balancing mass is five times that of the brush then for a working speed of the crankshaft of four times the natural frequency of oscillation'of the balancing mass 3 a reduction is obtained in the reaction force to 5.5% of the usual rigid arrangement, while the amplitude of the oscillation is 18% of the crank radius. In apparatus according to the invention the minimum brush operating frequency is at least 1.5 times the maximum natural frequency of oscillation of the suspended balancing mass or masses. As shown in Figs. 2b, 2c and 2d a paper web 6 is passed over coating mechanism 7 and around coating drum 9 whereon it is subjected to the action of brushes 2, which are connected by connecting rods 5 to crankshaft 10 driven by Cardan shaft 15 and bevel gears 16.

Abstract: 734,332. Statistical apparatus. MAUL, M. Aug. 10, 1953 [Sept. 5, 1952], No. 22065/63.. Class 106 (1). A record card controlled machine controlled by cards sorted into groups having a known group control device, which on group change, causes recording of the total of the data of the previously analysed card group is characterized in that simultaneously with the total recording, a group control number is recorded under the control of the last card of the previously analysed card group. The machine is shown diagrammatically in Fig. 1; detail cards sorted into groups are placed in hopper 11 and fed by rolls 13 past brushes bI, bII during which time the group control device of known form G compares the group number, and data is analysed by brushes bII into an accumulator Z of known form. When a group change occurs device G responds in known manner and feed rolls 13 are stopped and a summary card from hopper 12 is fed by feed rolls 16, which are now started, under the punch L for punching of the total in the accumulator. Simultaneously with this operation the last detail card of the group is fed past a third set of brushes bIII by feed rolls 14, which are revolving continuously, and the group control number is sensed by brushes bIII and punched on to the summary card with the accumulator total. In this way a separate accumulator for the group control number is no longer required. Fig. 2 shows the main driving motor for driving the continuously rotating shaft 18 through gearing and the provision of clutches 19, 20 and 21,22 which are magnetically operated to start and stop the drive to feed rolls 13 and 16 as required by the sequence of operation described above, and controlled by the group change control device G. The known form of accumulator employed is described with reference to Fig. 3 in which clutches 42 are mounted on a shaft 41 and are actuated by electromagnets Z. When one of the magnets Z is energized it attracts its associated armature 45, releasing lever 44 and causing clutch 42 to engage and drive through associated gearing an insulated brush holder 59 mounted on shaft 58 until the brush is opposite the segment 62 corresponding to the value of the hole detected in the card by brushes bII. Known refusing and transfer devices are incorporated in the accumulator.
