Title: Gas scrubber
IPC: B01D47/06
Filed: 1967-07-27
Abstract: In a method of removing particles from a gas, a condensable vapour, e.g. steam, is added to the particle-laden gas and subsequently condensed and condensed droplets containing particles are removed from the gas, the amount of condensable vapour added to the gas being controlled by the difference in temperature between the particle-laden gas and the mixture of such gas and the condensable vapour. The condensable vapour may be injected into the particle-Laden gas or the particle-laden gas may be bubbled through a body of a vaporisable liquid maintained on a bubble tray having means to heat the liquid. The condensable-vapour may be condensed by contacting the mixture of gas and vapour with tubular cooling elements and the condensed droplets removed by filtration. Alternatively the gas and vapour may be passed through a body of liquid maintained on a bubble-tray having means to cool the liquid. The removal of the particles from the gas may take place in a number of superposed stages.

Title: Signal translating system providing amplification and limiting
IPC: H03F1/30
Filed: 1967-12-26
Abstract: A limiting amplifier comprises a transistor having collector and emitter resistors, the collector being directly coupled to the base of a second transistor which is connected as an emitter-follower and has a further resistor in its collector circuit, whereby input voltage swings of one polarity forward bias the base-collector junction of the second transistor and drive it into saturation, whereas voltage swings of the opposite polarity reduce the collector current of the first transistor and drive the second transistor into saturation. The limiting may be made symmetrical by appropriate choice of the resistor values. Fig. 6 shows portion of a TV intercarrier-sound amplifier using two stages as defined above, viz. transistors 216/218 and 232/234. The circuit is generally similar to that of Specification 1,127,801 and the initial stages differ only in the presence of resistors 224 and 240 which provide the above-described limiting function. These resistors may be replaced by one or more diodes with or without series resistors. The whole circuit within the dotted line may be formed as one integrated circuit. Transistors 308, 316 and 318 provide biasing voltages which are compensated for changes in temperature or supply voltages as described in Specification 1,206,479. Transistors 312 and 314 provide similarly stabilized collector potentials. The output from transistor 234 is applied to a further limiter 246/248 which is supplied from a higher potential than the earlier stages. The output of this limiter is taken to a discriminator transformer 254, ratio detector 264/266 (as in Specification 1,124,276) and A.F. amplifier 278-292, all these (except for the transformer) being on the same integrated circuit as the I.F. stages. The signal from transistor 292 is taken to an output stage 328 as shown, or alternatively transistor 292 may be a phase-splitter feeding a Class B output stage. Transistors 312, 314 and 316 may be replaced by diodes (Fig. 5, not shown).

Title: Method of moving viscous crude oil through a pipeline
IPC: B67D7/32
Filed: 1968-01-10
Abstract: A method of transporting crude oil through a pipe-line by injecting a mixture of crude oil and an aqueous solution of non-ionic surfactant into the pipe-line to contact the crude oil and to effect a flowing pressure drop decrease in the pipe-line and thereafter reducing the flow of surfactant solution being injected into the pipeline to less than 5% of the crude oil concurrently injected into the pipe-line to maintain the flowing pressure drop decrease. The injected aqueous solution forms with the oil an oil-in-water emulsion at the initial stage, thereafter the flow being reduced may be to 2% of the flow of oil, or even nothing. The surfactants may have ether or esther linkages and may be dissolved in distilled, tap or seawater. A separation tank may be provided at the outlet of the pipe to separate the oil from the solution.

Title: Apparatus for filtering and dissipating microwave energy possessing undesired wave modes
IPC: H01P1/162
Filed: 1968-04-13
Abstract: An unwanted component of polarization is removed from a waveguide 1, of, e.g., circular section, by a slot 2 which communicates with a groove 4 in a cover-plate 3 of dissipative material. The sides of the groove are flush with the sides of the slot except at the ends where the slot is provided with impedance-matching sections 5 of restricted width. The groove does not extend to the ends of the matching sections and the outer parts of these sections are terminated by short lengths 6 of the surface of the plate 3. The length of the slot 4 is adjusted such that the reflections from the two surfaces 6 cancel each other. Alternatively, the overall length of the groove is made equal to the overall length of the slot.

Title: Mineralocorticoidal 3-ethers
IPC: C07J5/00
Filed: 1968-12-12
Abstract: Novel steroids of the formula (wherein R1 is C 1-10 alkyl or C 3-7 cycloalkyl and R2 is a free or esterified OH group) and the ester salts of the acidic and basic 21-esters are prepared (1) by etherification of the corresponding 3-ols or reactive derivatives thereof with appropriate alcohols R1OH or reactive derivatives thereof or (2) by removal, by reaction with zinc in aqueous acetic acid, of the 17[alpha]-OH group from corresponding steroids containing this group or (3) by solvolysis or hydrogenolysis of corresponding steroids in which the 20-keto group and/or the 21-R2 group is or are functionally changed. Free 21-ols may be esterified. Starting materials of the formula are prepared by reduction of the 3-keto group of desoxycorticosterone possibly after esterification or etherification of the 21-hydroxy group and/or conversion of the 20-keto group to a functional derivative, to give a mixture of 3[alpha]- and 3#-ols which may be separated and protective groups if present then split off. The mixture of the individual epimers can be converted to reactive derivatives of the 3-ols, e.g. 3-halo compounds or 3-sulphonates, by standard procedures. Starting materials of the formula are prepared by reducing the bis-methylenedioxy derivative of cortexolone (prepared conventionally) to give a mixture of the epimeric 3-ols, splitting off the protecting group and etherifying, if necessary via a 3-ester or similar derivative, the epimers being separated at any appropriate stage. The novel 3-ethers of 3-hydroxy-21-(hydroxy or acyloxy) - 4 - pregnen - 20 - one are stated to possess a sodium-retaining and diuresisinhibiting action of the same order as that of 9[alpha]-fluoro-hydrocortisone and therefore to be useful for combatting Adison's disease and hypotonia. They may be made up into pharmaceutical compositions with suitable carriers.

Title: Manifold imaging machine
IPC: G03G17/08
Filed: 1972-01-04
Abstract: An apparatus is disclosed for use in the manifold imaging process wherein a rotatably mounted drum shaped electrode is contacted by an electrically photosensitive imaging layer residing on a substrate. The substrate is directed in a predetermined path bringing the electrode and the imaging layer into contact during the rotation of the drum. During rotation an electrical device places an electrical potential across the imaging layer while an optical arrangement permits exposure of the imaging layer to imagewise pattern of electromagnetic radiation to which the imaging layer is sensitive either before or while in contact with the rotatable electrode. Subsequent to exposure the substrate is separated from the rotatable electrode whereupon the imaging layer fractures in imagewise configuration conforming to the imagewise exposure of the imaging layer providing a positive image on one of the substrates and electrodes and a negative image on the other. The image residing on the rotatable electrode is removed and the electrode is rotated to receive additional imaging layer for the production of additional copies.
