Title: Data processing system
IPC: G06F15/16
Filed: 1966-01-18
Abstract: 1,119,421. Data processors. INTERNATIONAL BUSINESS MACHINES CORP. 18 Jan., 1966 [16 Feb., 1965], No. 2228/66. Heading G4A. Data is transmitted between two data processing devices via a buffer adapter linked to both devices by data and control channels, which also link the data processing devices to respective groups of input/output devices. Two or more computers are linked together and to input-output (I-O) control units (each controlling one or more input-output devices) by one or more adapters. The channels linking a computer to an adapter comprise a 9-wire data channel (8 bits plus 1 parity bit) from the computer (" bus out "), a similar channel to the computer (" bus in "), tag lines in and out indicating the type of information on the associated bus (e.g. data, address, command, status), various interlock lines, a loop enabling the I-O control units to be scanned in turn, and a suppress out line for preventing presentation of status information or data to the computer. When a first computer (any one) requires to send data to a second computer (any other) it sends the address of the appropriate adapter (priority between adapters is also mentioned) which responds by raising an interlock line to the first computer. The latter drops the address signals whereupon the adapter returns the address to the computer which then sends a write command to the adapter. The adapter attempts to interrupt the second computer. The latter, when ready, issues a sense command to the adapter which in response supplies to the second computer, the (write) command from the first (which was stored in the adapter). The second computer generates a read command and the adapter supplies status information to the first. A comparison is made in the adapter to assure that both computers are not executing the same command. Provided they are not, the adapter signals for successive bytes of data from the first computer and transfers them via a buffer to the second computer. When all the data has been transferred, the first computer issues a stop command to the adapter which generates a status signal and then disconnects from both computers whereupon the latter proceed to scan their respective I-O control units independently. If the comparison (see above) had indicated the same command was being executed, an appropriate status signal would be provided to the initiating computer and the adapter would disconnect. A test I/O command can be used to determine the status of the adapter.

Title: Process of recovering phosphorus from phosphorus sludges
IPC: C01B25/02
Filed: 1939-01-25
Abstract: 524,289. Phosphorus. I.G. FARBENINDUSTRIE AKT.-GES. Jan. 25, 1939, No. 2658. Convention date, April 29, 1938. [Class 90] Yellow phosphorus is recovered from the sludges occurring when phosphorus obtained by the thermal reduction of phosphates is condensed in the presence of water by heating such sludges in a closed vessel under reduced pressure to a temperature closely below the boiling point of water under atmospheric pressure, until all the water has distilled off. The reduced pressure may be applied in a single or in several stages : in the latter case, the sludge may be heated under moderately reduced pressure in the first stage and transferred to a second vessel to remove the remainder of the water under a lower pressure. The recovery may be carried out in the scrubber in which the phosphorus is initially condensed, by making it pressure resistant and providing a vacuum connection. When full, the lower layer of molten phosphorus is tapped off. Then the supernatant water is pumped off, and finally the intermediate sludge is treated.

Title: Improvements in heat exchangers
IPC: F23M20/00
Filed: 1953-02-02
Abstract: 729,793. Heating air for combustion. FOSTER WHEELER, Ltd. Feb. 2, 1953 [May 29, 1952], No. 2932/53. Class 64 (1). In a heat-exchanger in which heat is exchanged between two fluids through a thermal conducting wall, the hot fluid flows in two streams and the cold fluid in a single stream, first in the same general direction as one of the hot streams and then countercurrent to the other. In the form shown hot gases from a combustion chamber 15 pass to a flue 20 and thereafter divide into two streams, one stream passing through the tubes of a heat-exchange section 30 comprising series-connected tube groups, and the other stream passing through the tubes of a heat-exchange section 31. The two streams of cooled gas are reunited at the stack 37. Cold air for combustion in the furnace chamber 15, is blown by a fan 28 over the tubes of heat-exchange section 30 in the same general direction as the gas flow through the tube groups, and thereby receives heat. The heated air is then directed countercurrent to the gas stream, over the tubes of heat-exchange section 31 where it receives further heat before passing through duct 17 leading to burners 16. This arrangement it is stated, reduces the risk of corrosion in the air heater by condensation from the cooled flue gases. The gas flow through the respective sections 30, 31 may be controlled by dampers 43, 44. The streams of heating fluid may come from separate sources and may leave the apparatus from separate outlets. The air to be heated may flow through the tubes and the other heating gas over the tubes.

Title: Improvements in or relating to gasification of carbonaceous solids
IPC: C10J3/46
Filed: 1950-02-07
Abstract: 668,941. Water-gas generation. STANDARD OIL DEVELOPMENT CO. Feb. 7, 1950 [Dec. 1, 1949], No. 3162/50. Classes 55 (i) and 55 (ii). In a fluidized water-gas process a halide is added to a gasification zone, in which carbonaceous solids are being reacted with steam and oxygen, to repress the formation of carbon dioxide in favour of carbon monoxide. The halide is present in amounts of about 0.01-5 per cent and preferably 0.05-1 per cent based on the percentage of carbon in the reacting mass of solids. The preferred halide is sodium chloride but the halides of potassium, lithium, rubidium, caesium, barium, magnesium and calcium may also be used. As shown in the drawing particulate coke preheated in a hopper 1 is fed to a fluidized gasification zone 10 and sea-water or brine is introduced through the line 5 in a proportion of 25-100 gallons of sea-water per ton of coke feed. Steam and oxygen are fed through the lines 12 and 14 and water-gas is withdrawn through the line 22 and heat exchanger 24 passing to a scrubber 30 where any free halogen is washed out of the gas. Gasification residue is withdrawn from the zone 10 by the line 35 passing to an extractor 40 where sea-water is used to extract the soda-content of the ash; the washing liquid being passed to the scrubber 30 where after use it forms the whole or part of the sea-water supplied to the line 5. A temperature of 1700-1800‹ F. is maintained in the generator and the water-gas produced contains less than 5 per cent of carbon di-oxide. The process may also be applied to a two-vessel fluidized solid system in which heated solids are circulated to a gasification zone from a separate heating zone to supply part of the heat required for the process.
