Title: Valves for fluids
IPC: F15B13/10
Filed: 1971-08-05
Abstract: 1338815 Valves NUMATICS Inc 5 Aug 1971 [6 Aug 1970] 36885/71 Heading F2V In a spool valve 14 which is subjected on the one hand to the bias of a spring 20 and on the other hand to the pressure within a pilot chamber 24, a suplementary manual control is afforded by and arrangement consisting of a cap 22 and a plunger 34, the cap being securable to the valve housing 12 and the plunger carrying a radially extending projection 68. The interior of the cap is formed with a narrow bore 28 which, in turn, is formed with three slots 50, 54, 58 with which the projection 68 co-operates to define different operational characteristics of the control arrangement. The first, or central, slot 50 extends along the entire extent of the narrow bore 28 thus permitting the plunger 34 to be moved into the cap such that the projection engages the end face of the cap, such engagement being possible only when the cap is free from the valve housing. Disposed one on either side of the central slot 50 are two further slots 54, 58 both of which are blind. Slot 58 is laterally extended to define a backing recess 62, 64. Prior to assembly of the cap 22 on the valve housing, the plunger extension 68 is moved over the cap end face into engagement with either one of the slots 54 or 58. Thereafter the cap is mounted on the valve housing. With the extension 68 in slot 54, the plunger can be manually displaced in a purely longitudinal sense, against a spring 44, to alter the operative state of the spool valve 14. Once the manually applied actuating force is removed, the plunger projection returns to the end 56 of slot 54. When contained within slot 58, the plunger can be merely reciprocated manually, as in the case of the projection in within slot 54, or can be displaced longitudinally and then turned such that the extension 68 engages lock shoulder 64. In such state, the spool valve is restricted in its movement to the right, as seen in Fig. 1.

A gasoline containing acyclic mono-olefines together with at least one diolefine, and containing sulphur substantially entirely in the form of thiophene, is improved by hydrogenation of the gum-forming constituents using a supported nickel catalyst, which is present in major amount as elemental nickel, wherein the process is started up with the gasoline to which sulphur has been added so that sulphiding of the catalyst to a lever of from 0.01 to 0.2 gram atoms of sulphur per gram atom of nickel occurs, and thereafter passing hydrogen and the gasoline without added sulphur over the catalyst, the temperature, pressure, hydrogen flow rate and feedstock flow rate being so correlated that the diolefines are converted substantially completely to mono-olefines, without appreciable conversion of acyclic monoolefines to saturated hydrocarbons. The nickel may be supported on alumina, kiesulguhr, chalk, silica gel, or sepiolite. The added sulphur may be in the form of thiophene, dihydrothiophenes, thiocycloalkanes having at least 4 carbon atoms per ring (e.g. thiocyclopentane and substituted thiocyclopentanes), substituted thiophenes and dihydrothiophenes, monosulphides of the general structure RSR<SP>1</SP>, cyclic monosulphides containing one sulphur and at least 5 carbon atoms in the ring, substituted cyclic monosulphide, sulphur, mercaptans, aliphatic vicinal disulphides, carbon disulphide, and hydrogen sulphide, and mixtures of the above.

Abstract: 1,155,052. Automatic control of chemical apparatus. SOC. NATIONALE DES PETROLES D'AQUITAINE. Aug.23, 1966 [March 8, 1966], No.37737/66. Heading G3R. A controlling variable of a chemical process is automatically regulated by an electronic controller in dependence on the composition of a sample of effluent of the process, the sense of regulation being determined by the rate of change of another measured variable of the process. In Fig. 1, gas containing H 2 S is introduced at 3 into a reaction vessel 4. Air for combustion is supplied through an adjustable valve 1 and, after reaction, the gases are passed to a condenser 5 from which sulphur is discharged at 6. The remaining gases pass to a catalytic converter 7 which adjusts the air content and recovers further sulphur at 10. The waste gases, which pass to a chimney 15 are analyzed at 13 and two electrical signals are produced for control through a computer 16. One electrical signal 18, representing the SO 2  content, has first and second derivatives added and is utilized to control a servo-mechanism 2 adjusting air valve 1 to obtain optimum conditions. The appropriate sense of adjustment is determined by the other electrical signal 17 which is produced as the result of infrared analysis of oxidation of the waste gases. This oxidation takes place in an auxiliary furnace supplied with the waste gases, air, and methane at controlled rates, and, if there is a change of temperature, as determined by a thermocouple associated with a differentiator, indicating the presence of H 2 S, one sense of adjustment is called for by signal 17, whereas if there is no change of temperature, indicating that there is only SO 2  corresponding to excess air, the other sense of adjustment is called for by signal 17. Control by the computer is effected in a sequence of switching operations which is repeated at intervals or whenever deviation from the optimum exceeds a predetermined value.
