Title: Improved process for deodorizing waste liquors from oil refining processes
Inventor: KNOX JAMES GIBSON
IPC: C10G19/08
Filed: 1955-10-14
Abstract: Spent caustic alkali solution from a petroleum refining process is deodorized for discharge into a liquid environment, e.g. the sea, by reducing the pH to below 8,5, preferably to 7,5-8,5, by the addition of aqueous acid, e.g. 60-98 per cent. sulphuric acid, and thereafter stripping with carbon dioxide-containing gas, preferably at a temperature of 100-200 DEG F.  The pH is preferably not reduced to below that of the liquid environment.  When this is sea water the pH is preferably adjusted to approximately 8. The carbon dioxide-containing gas may be flue gas, and is preferable used in admixture with steam.  The stripping may be a batch process or a continuous process with countercurrent flow. After stripping the spent caustic alkali solution in the continuous process, the carbon dioxide-containing gas may be used to strip hydrogen sulphide-containing water in similar manner.
Patent GB-1203189-A (GB)
Title: Circuit for controlling a driving device having an electromagnetically-actuated clutch
IPC: H02P3/04
Filed: 1969-06-11
Abstract: 1,203,189. Clutch control. SINGER CO. 11 June, 1969 [17 June, 19681, No. 29497/69. Heading F2L. An electromagnetic clutch coil 10 is initially over-excited to provide rapid clutch engagement by discharging a storage capacitor 41 through the coil 10 when a silicon controlled rectifier (SCR) 25 is triggered on closing contacts 53, the capacitor having previously been charged by an A.C. voltage on busses 14, 15 when an SCR is triggered, and the clutch being maintained engaged, after the capacitor has discharged, by a D.C. voltage on busses 18, 20. As shown, the circuit controls the clutch coil 10 and a brake coil 11; contacts 55, a storage capacitor 46, and SCR's 31 and 45 controlling the brake. On closing contacts 55, a capacitor 50 discharges through a diode 52 and the contacts to provide a trigger pulse to the gates 56, 62 of SCR's 31, 40 respectively, conduction of SCR 40 ceasing when capacitor 41 is charged up to the A.C. voltage on busses 14, 15. The positive voltage on capacitor 46 is initially greater than that on bus 18 so that diode 32 is back-biased and does not conduct until capacitor 46 has discharged through diode 66 and the brake coil 11 to engage the brake. Diode 66 is then back-biased, and diode 32 conducts, the brake being maintained engaged by the D.C. voltage. The D.C. voltage on capacitor 68 turns off SCR 25 when SCR 31 conducts. If the push-button 57 is then depressed, opening contacts 55 and closing contacts 53, capacitor 50 triggers SCR's 25 and 45 into conduction and the capacitor 68 turns off SCR 31. Capacitor 41 discharges to initially over-excite clutch coil 10, and then diode 26 conducts to maintain the clutch engaged. A " fail-safe " circuit 19 is automatically operative to engage the brake in the event of line voltage failure. A unijunction transistor 69, resistances 70-72, and capacitor 73 form a known relaxation oscillator having a period of 12 milliseconds, capacitor 73 being prevented from charging by a transistor 80 which is driven into saturation on each half-cycle of line voltage. On line voltage failure, transistor 80 turns off, and supply voltage in a capacitor 75 allows capacitor 73 to charge. 12 milliseconds later the unijunction transistor 69 breaks down allowing capacitor 73 to discharge through resistance 72 to trigger SCR 31 and allow capacitor 46 to discharge through brake coil 11 to engage the brake. Indicator bulbs 36, 37 light up when the clutch or brake respectively is engaged. Again, Fig. 2, (not shown), recharging of either capacitor 41 or 46 substantially immediately it has discharged is provided to prevent rapid actuation of button 57 from " beating " either storage capacitor. The capacitors are charged in series with respective diodes (81), (82), through a single SCR (83) triggered by a one-shot multivibrator (86), itself triggered by pulses from the button 57. The multi-vibrator (86) also triggers an SCR (95) connecting busses 20 and 15 to complete the discharge path for capacitor 41 or 46 through their respective coil 10 or 11

Filed: 1934-10-16
Abstract: 450,528. Automatic control systems. SOC. ANON. DE PUBLICATIONS PERIODIQUES (IMPRIMERIE E. DESFOSSES), 13, Quai Voltaire, Paris. Oct. 16, 1934, Nos. 29642 and 29643. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 17, 1935]. [Class 38 (iv)] [See also Group XVI] Registration.-Apparatus for determining the relative positioning of several prints or the like on the same support, for example multicolour prints on a web in a rotary printing- machine, comprises means on some of the printing-rollers or the like for producing register marks on the prints or the like, and means comprising photo-electric cells and relays for automatically controlling register. For multicolour printing of a web b, the web passes over adjustable registering-rollers a<20>, slidably supported in guides a<30>, which are arranged between the printing-rollers a<1>. For each or some of the latter there are provided marking means, either formed on the edge of the cylinder or on a separate member attached thereto, which print on the web, so that when all the cylinders are in the correct relative position, the marks A partly overlap or are situated at definite distances from one another. The marks may be in the form of dots, circles, &c., and may serve for transverse as well as longitudinal registration. Alternatively other marks m in the form of a straight line printed by each cylinder, and all overlapping when in register, or of a number of broken straight lines printed by each cylinder but forming one straight line when in register, may be used. A number of intermittent light sources illuminate a number of photo-electric cells, there being as many light sources as cylinders, but two cells to each light source which are displaced somewhat to one another along the path of the web, so that if a mark arrives early or late a cell is energized and operates a relay to adjust appropriately the position of a registering-roller a<20>, while if the particular printing cylinder is in its correct position the appropriate mark obscures both cells at the moment of illumination ; in this case the marks are in groups, those forming a group being equidistant from one another. A continuouslyilluminated light source may be used, and in this case the registration marks are in the form of transparent strips crossing opaque bands printed by each cylinder along the edge of the web. When the cylinders (two only being used in this system) are in register, the two transparent strips form a straight line and, upon reaching two photo - electric cells arranged side by side beneath the path of the bands printed on the web, have no effect thereon. If there is lack of register, one strip arrives before the other and energizes its cell to initiate a correction, which ceases when the second strip arrives at the second cell. The device may be applied to printing on both sides of a web.
