Abstract: 231,513. Vogt, E., and Kirchhof, L. March 26, 1924, [Convention date]. Pulverulent-fuel furnaces; regenerators.-A reversible regenerative melting or heating furnace fired by pulverulent fuel is provided with two hearths arranged side by side or in tandem and adapted for use alternately for the preliminary and final heating of the material, the supply of air for combustion of the pulverulent fuel being heated by the waste gases in regenerators arranged at the ends of two hearths. Figs. 1 and 3 show the hearths I, II, arranged side by side. When hearth I is being heated by the burner i, the gases pass over the hearth II and through the flue a to the tubular regenerator g and thence to the chimney flue through the valve c. The air for combustion is supplied by a pipe d to pipes e, which serve to cool the dividing wall between the hearths, and then passes through a three-way valve f to the regenerator g and pipe h to the burner i. Upon reversal of the course of the gases, the waste gases escape through the flue k to heat the regenerator l from which air passes to the burner above the hearth II. In a modification shown in Figs. 5 and 7 in which the hearths I, II are arranged in tandem, the air for combustion passes through a three-way valve q to one or other of the regenerators u by way of pipes t and thence through a pipe v to the burner w at the opposite end of the furnace.

Title: Improvements in record card controlled machines
Filed: 1954-03-22
Abstract: 753,048. Statistical apparatus. MAUL, M. March 22, 1954 [March 27, 1953], No. 8353/54. Class 106 (1). A record card controlled machine in which groups of item cards passing through the machine are computed in accumulators and wherein a summary card is provided at the end of a card group under the control of the accumulators by a punch having a single row of punches is characterized by the provision of shifting means for moving the card and the row of punches twice relatively to each other, and by means for controlling in the first shifting movement the summary card punching device synchronously with the passage of the first item card on item card analysers, and by means effective on total taking for shifting the summary card in the second shifting movement synchronously with the analysis of the setting of the accumulators past the punching device and for controlling the latter in accordance with the setting of the accumulators. Item cards are fed from magazine 11 and pass analysing brushes bI, bII which detect group control numbers to pocket 12. Brushes bII also direct the item card entries to the accumulators. A blank card is fed by rolls 18, 19 from magazine 13 to the punches 21 synchronously with the first item card fed to brushes bII and the data from the first item card is reproduced on the blank card by punches 21. The blank card is held stationary after punching while the item cards continue to pass through the machine, the amounts being entered into the accumulators. If a change of group number is detected the item card feed is stopped, the blank card is moved backwards under the punches 21. At the same time the accumulators control the punching of the total into the card. On its return movement the card is diverted from its path by the deflector 22 and is deposited into the pocket 14 after punching. The drive for the blank cards and summary cards is effected step-by-step by a Maltese drive 31 via a magnetic clutch K2 and constantly rotating shaft 34. Step-by-step rotation of the gear 35 causes the plate 36 to be moved to the right or to the left, Fig. 2. Movement of the reversing gear to the left causes the card to be fed below the punches to the right, punching of designation data being then effected. Movement of the reversing gear to the right causes the card to be moved to the left when punching of the total takes place. One reciprocating movement of the reversing gear corresponds with forty-three steps of the Maltese drive. The reversing gear also drives the card knife 15 below the magazine 13 for the blank cards. The control of the punching device is effected by means of punch selector magnets W. If one is energized it attracts its armature 23 which moves its associated selector bar 20 to the left, Fig. 1, causing the full depth of the bar to register under the punching yoke 25.

Title: Improvements in or relating to methods of preserving foods
IPC: B65D81/20
Filed: 1931-03-19
Abstract: Food is preserved in containers by subjecting it therein to a vacuum sufficiently high and for a period sufficiently long, e.g. 10-50 seconds, to remove air and initiate the evolution of water vapour which drives off part of the occluded air from the food, next supplying an inert gas, e.g. carbon dioxide, to the containers and finally sealing them.  The containers may be filled with inert gas at substantially atmospheric pressure.  The process may be applied to dry goods, e.g. dried milk, sufficient water being still present therein.

Abstract: 925,162. Gating circuits. BELL PUNCH CO. Ltd. June 15, 1959, No. 8502/60. Divided out of 925,161. Class 40 (6). The rise time of the output pulse of a gate circuit is decreased by superimposing on the steady supply voltage a periodic component in synchronism with an input pulse. Fig. 2 shows the supply voltage waveforms, +GD being a nominal +50 v. and - GD a nominal - 25 v., applied to the diode gate circuit of Fig. 1 (which forms part of a complete keyboard-operated calculator described in Specification 925,161 which derives a function T2.S1+PD1.MD0. TD5+T3.S2 from the inputs to diodes 11RW1-7. These inputs are between -15 and - 25 v. for " 0," and +15 v. for " 1," the S1, S2 and PD1 inputs being short pulses (S1 and S2 inputs being in fact derived from tube PD). When the inputs to 11RW2-3 (say) are +15 v. the rise to +15 v. of PD1 to cut off 11RW1 will cause a rise in the input to 11RW10, the rise time being dependent on the shutdown capacitances of diodes 11RW2-3; at this instant the +GD supply rises to about +80 v. to reduce this rise time of the positive output pulse applied to 11RV grid. A similar action takes place due to the negative pulse on -GD at the end of PD1, S1 and S2 pulses to assist in rapid closing down of diode 11RW1.

Title: Process for the conversion of carbon monoxide with hydrogen into hydrocarbons
IPC: C07C1/04
Filed: 1939-03-17
Abstract: 526,465. Hydrocarbons. POTTS, H. E. (Naamlooze Vennootschap Internationale Koolwaterstoffen Synthese Maatschappij). March 17, 1939, No. 8508. [Class 2 (iii)] Hydrocarbons containing two or more carbon atoms are prepared by converting a mixture of 2 parts by volume, or less of hydrogen to one part by volume of carbon monoxide according to known synthetic methods, and at intervals using a gas mixture richer in hydrogen containing at least 2.5 parts by volume of hydrogen to one part of carbon monoxide in order to revivify the catalyst without interfering with production. Thus, the synthesis proper may be effected with a gas containing 30 per cent. carbon monoxide and 60 per cent. hydrogen, and when the activity of the catalyst has decreased, it is reactivated with a gas containing 15 per cent. of carbon monoxide and 75 per cent. hydrogen, or 12 per cent. carbon monoxide and 80 per cent. hydrogen, the remainder being inert gases. The process may be carried out by the simultanous conversion of each gas mixture in a separate reaction chamber, with interchange of the gas mixtures at intervals. The synthesis gases may be prepared by the gasification of coke, bituminous or brown coal, or by conversion of natural or refinery gases with steam and carbon dioxide, or by incomplete combustion of natural gases. The gas mixture richer in hydrogen may be obtained by adding electrolytic hydrogen to carbon monoxide or synthetic gas, by treatment of part of the synthesis gas with steam, by cracking the residual gases from the synthesis which contain hydrocarbons, or by partial conversion of the carbon monoxide in a part of the synthesis gas with steam followed by elimination of the carbon dioxide. Catalysts mentioned are fused ferrosoferric oxide which may contain silicon and titanium, sintered iron catalysts, mixtures of cobalt with thorium oxide, and nickel catalysts. Temperatures of 170-370‹C. are referred to, and pressures of 5 atmospheres upwards. An example is given.
