Title: Removal of heat produced by the compression of a gas or gas mixture
IPC: C07C1/00
Filed: 1974-10-15
Abstract: 1449076 Cooling gases by contact with liquids LINDE AG 15 Get 1974 [19 Get 1973] 44739/74 Heading F4K In a method for removing the heat generated when gas such as cracked hydrocarbon gas is compressed by multistage compression, the compressed gas is cooled in each compression stage by direct contact heat exchange with coolant liquid, e.g. water. As shown cracked gas supplied through a line 1 is compressed from 1 at. to about 33 at. in stages by means of compressors 2, 4, 6, 9 and 12, with the gas being cooled in each compression stage in spray coolers 3, 5, 7 and 10. Each spray cooler contains filler bodies to increase the heat exchange surface therein, and a filter 26 is provided in its upper region to prevent the gas from carrying over coolant liquid droplets into the next compression stage. A closed water circuit provided for cooling the cracked gas includes a pump 14, coolers 15, 18, 20 and expansion valves 17, 19, 21. The coolers 18 and 20 serve to cool the heated coolant water leaving one spray cooler prior to it entering the adjacent cooler. A liquid mixture consisting of water together with high boiling hydrocarbons in the benzine range condensed in the spray coolers 3, 5, 7 and 10, is withdrawn through a line 22 into a separator 23 wherein the hydrocarbons are separated from the water and withdrawn through a line 24 for further treatment, whilst the water is recycled through a line 25 to the pump 14. After the cracked gas has been compressed in intermediate compressor 6 to about 9 at. and recooled in spray cooler 7 to 30 C., it is subjected to an alkaline wash in a washing device 8; cracked gas leaving the last spray cooler 10 is subjected to glycol drying in a device 11 before being compressed in compressor 12 to a final pressure of 33 at. At this pressure the cracked gas is fed to a low temperature separation apparatus (not shown) in which it is separated into its components, i.e. primarily into hydrogen, methane, ethane and ethylene.

Abstract: 1345218 Controlling power to X-ray tube PICKER CORP 15 Oct 1971 [30 Nov 1970] 48094/71 Heading H2H [Also in Division G4]  A system for controlling power to an X-ray tube is adapted to take account of diminishing maximum power rating with increasing exposure time and utilizes a comparison between a time varying voltage curve set up using predetermined data concerning the particular tube in use and a constant voltage indicative of the setting of a power source to supply the tube, a NAND gate being enabled to allow power to pass to the tube only when the time ranging voltage is greater than the constant voltage. As shown, a circuit 14 which comprises a plurality of switches and relays produces a signal on one of a number of outputs indicative of a mode of operation of the tube, e.g. small, large focal spot, and this signal causes a voltage to be applied across one of a corresponding plurality of sets of 4 potentiometers at 16 which supply a voltage to the bases of 4 transistors at 18, each voltage value being set in accordance with the predetermined characteristics of the tube in use. A circuit 20 produces sequentially a series of binary words at regular intervals which are applied to a matrix type A/D converter (see Division G4) to produce a series of progressively diminishing voltages at AF-AH which are applied as collector voltages to the transistors, and the output AE (V 2 ) of circuit 18 comprises a descending staircase voltage curve, the precise form of which is determined by the potentiometer settings. A voltage indicative of the current derived at VR-1, and a second voltage indicative of the voltage derived at VR-2, delivered by a supply source are added to produce a voltage (V 1 ) and this is applied to a comparator circuit 12 together with (V 2 ). The variable resistances VR-1, VR-2 are preferably sets of parallel connected fixed resistances selectively switched and gauged with the controls of the supply source. The difference signal is amplified and inverted and the NAND gate 30 prevents further power being applied to the tube when the derived curve level falls below that of the supply power.
