Title: Process for the desulphurization of pyridine and its homologues
Inventor: SMEYKAL KARL
IPC: C07D213/06
Filed: 1965-04-07
Abstract: Pyridine and its homologues which are contaminated with sulphur compounds are desulphurized by treatment with an amount of hydrogen, or hydrogenous gas, which greatly exceeds that theoretically required to decompose the sulphur compounds, at 200-350 DEG  C. and at a superatmospheric up to 100 atm. in the presence of a sulphide and/or oxide of an element or mixture of elements of Group VIA, VIIA or VIIIA.  Specified catalysts are the oxides and sulphides of W, Mo, Ni, Co and Fe. The catalysts may be supported on a carrier (see Division B1). After desulphurization the pyridine bases are separated from the H2 and subjected to fractional distillation.  The hydrogen gas used in the process is treated to remove impurities, e.g. H2S, volatile hydrocarbons, which may accumulate.  Examples relate to the purification of pyridine and a picoline mixture.ALSO:Catalysts for the desulphurisation of pyridine bases by treatment with hydrogen comprise sulphides and/or oxides of elements in sub-groups VI to VIII.  The compounds may be supported on carriers, e.g., alumina, silica-gel or aluminium silicates. Specified catalyst compositions are WS2/NiS; M0O3/NiO and H0O3/WO3.  The catalysts containing sulphur are usually subjected to pretreatment with hydrogen.

Title: Liquid level control
IPC: G05D9/12
Filed: 1975-04-02
Abstract: 1507464 Liquid level control INDUSTRIAL DESIGN SERVICES (WATER TREATMENT) Ltd 2 April 1975 [3 April 1974] 14829/74 Heading G1H [Also in Division G3R] A liquid level control device for keeping e.g. water level in a boiler within close limits comprises liquid operated switch means 26 connected to a control unit 24 which opens and closes the infeed valve 20 to the liquid container 12. The control unit comprises identical high and low level circuits 28, 30 each having elements 36, 38, 40 consisting of a switch operating solenoid and a switch. Describing the high level operation as typical, the rising level closes switch 26 to circuit 28 in which only switch 2HW-1 of element 36 is closed. Power thus actuates solenoid 1HW closing switches 1HW-1 and 1HW-2, the latter after a 5 seconds delay. While 1HW-2 is still open, solenoid 3HW is actuated to operate means which moves valve 20 towards the closed condition. When 1HW-2 finally closes, solenoid 2HW opens 2HW-1 so that 1HW is deenergized opening immediately 1HW-1 and 1HW-2 so that movement of valve 20 ceases and solenoid 2HW is de-energized. After a ten second delay 2HW-1 automatically closes again so that if the level is still high enough to close switch 26, the operation above described is repeated, further closing valve 20. The circuit may be modified so that in the event of a power failure, the valve 20 will be fully opened or closed (not detailed). The switch member 26 may be one or two switches operated by known static probes and may have a built in time lag.

Title: Improvements in or relating to electric circuits including electron discharge devices having at least one secondary emissive electrode
IPC: H01J43/30
Filed: 1958-05-09
Abstract: 840,288. Photo-multiplier circuits. WESTERN ELECTRIC CO. Inc. May 9, 1958 [May 15, 1957], No. 14951/58. Class 40 (3). [Also in Groups XXXV and XL (c)] The current multiplication of a secondary emitting electrode in photo-multiplier is monitored by means which compares the current in or before the electrode with the current at a point after the electrode. The resulting signal may be used to maintain the gain constant. The Figure shows a photo-multiplier tube 10 comprising a photo-cathode 11, secondary emitting electrodes 12 and 13 and an anode 14. The voltage across the output anode load 15 and across a resistor 17 in the circuit of the secondary emitting electrode 13 are smoothed in circuits 42, 40, 50, 52 and on the occurrence of pulses at terminals 70, 71, 72, 73 are compared at the grid of a valve 60. The output of this valve is smoothed by a circuit 58, 59 and applied to the grid of a valve 61 in series with the H.T. supply to the multiplier tube. Variations of the ratio between the currents in electrodes 13 and 14 thus vary the supply voltage to the photo-multiplier tube in such a manner as to maintain the ratio and thus the gain of the tube constant. In an alternative circuit (Fig. 4, not shown), the gain of the photo-multiplier tube is controlled by means of a valve connected in series with one of the secondary emitting electrodes lying between electrode 13 and the anode, instead of in series with the main H.T. supply. It is also suggested that the control could be effected at a control electrode other than a secondary emitting electrode.
