Title: Improvements in or relating to electrical circuits employing cathode ray tubes
IPC: H02H3/40
Filed: 1935-10-14
Abstract: 453,248. Protective cut-out systems. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats-Unis, Montrouge, Seine, France. Oct. 14, 1935, Nos. 28357, 28358, and 28359. Convention dates, Oct. 12, 1934, May 21, 1935, and July 8, 1935. [Class 38 (v)] [See also Group XL] A circuit comprises a cathode - ray tube arranged in an electrical network with the generating voltage of the tube derived from the network and the deflection of the beam controlled by the electrical conditions in the network, whereby the beam is adapted to operate a protective, measuring or telemeasurement device or relay. The voltage of line 1 is rectified at 14 and smoothed at 15, 16 and impressed on the tube 2 so as to give rise to a beam 3, which is subjected to a field between deflector plates 5 proportional to the line current as derived from a current transformer 7, 4 being a concentrating coil. The beam strikes a fluorescent screen 9 and at a certain deflection of the cathode spot 8 from the centre 10, light from the screen passes through an aperture in a shutter 17 on to a photoelectric cell 11 controlling a H.F. transmitter 12. The transmission is received at a remote receiver 12<1>, but the circuit-breaker is operated only if the beam 3<1> of tube 2<1> energizes the cell 11<1>, which it is arranged to do if the fault is internal. With external faults the beam 31 is arranged to deflect in the same direction as 3, so 11<1> is not energized. The quantity measured by the deflection is the reciprocal of the line impedance, since the deflection is proportional to the field at 5, that is, to the line current, and inversely proportional to the line voltage. A graded impedance-time lag arrangement may be provided by means of a number of cells each controlling a relay. Rectifying and smoothing may be avoided by arranging for the A.C. voltage to be impressed directly on the tube, in which case the alternating field created by the network current upsets the deflection as the current is normally out of phase with the line voltage ; accordingly its phase is adjusted by an amount which is equal and opposite to the average phase angle between current and voltage, thereby reducing the alternating to the continuous current state. In Fig. 2, a screen 20, perforated at 21, is made of the same potential as, or of slightly negative potential with respect to, the anode, so that normally the rays 3 cannot strike the collector 22. On fault, the resistance 23 is traversed by current and the resulting p.d. across its ends is used to trip a breaker either directly or, after previous amplification, by polarizing the grid of a discharge tube. The latter arrangement permits amplification in the tube itself, by making the collector 22 of a material having strong secondary emissions.

Abstract: Textile material of cellulose and/or cellulose ester fibres is dyed or printed with a chromium or cobalt complex dyestuff free from nuclear sulphonic acid groups and derived from an #s : #s1-dihydroxy-, #s-hydroxy- #s1-amino- or #s-hydroxy- #s1-carboxy-azo-dyestuff containing once or twice the group SO2-CH=CH2 or -SO2-CH2-CH2,OSO3H and the material treate is subjected to the action of polyalkyleneamines, or their alkylation or quaternization products or mixtures thereof, and, especially when the dyestuff contains the -SO2-CH2-CH2-OSO3H group, an agent having an alkaline reaction.  The alkaline agent may be used before, after, or together with the polyalkylene-amine product, and treatment may be effected at room or raised temperature, or by steaming.  Preferred polyalkylene amines include a -o -polymethylene diamines, especially hexamethylene diamine ; polymerization products of ethylene-imine, alkylation products of these polymers and the corresponding quaternary ammonium compounds, especially a polymerization product of ethylene-imine which has been alkylated with dimethyl sulphate and converted into the quaternary ammonium compound ; condensation products of hard paraffins containing chlorine with polyethylene diamine, the latter being obtained from ammonia and ethylene chloride, and the completely methylated reaction products and quaternary compounds obtained from these condensation products by reaction with dimethyl sulphate; and quaternary compounds obtained by reacting dimethyl sulphate with polyalkylene-polyamines, especially diethylene-triamine or triethylene-tetramine.  Alkaline agents specified include alkali-metal and alkaline-earth metal hydroxides, e.g. sodium, potassium, calcium and barium hydroxides, alkali metal carbonates and bicarbonates, e.g. sodium and potassium carbonates and sodium bicarbonate, and alkali metal phosphates.  Dyeings and prints made by the process of the invention show good fastness to wet processing and to light. Examples are given.

Title: Improvements in or relating to thermal control devices
IPC: H01H37/14
Filed: 1926-11-13
Abstract: 261,407. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Gano, H. S.). Nov. 14, 1925, [Convention date]. Thermal switches. - A device for regulating the temperature of water, &c. comprises a main bimetallic element or coil 30 which when cooled or heated by the water rotates a shaft 31 and causes a contact 41 to engage either a contact 82 or a contact 79, thereby closing a, circuit to an electromagnet 85 or 95 and moving a reversing switch 87 into one or other of its end positions in which a circuit is closed to a motor 88 which then rotates a shaft so as to open or close a valve 89 allowing or preventing the entrance of steam into the water. The coils 85, 95 of the reversing switch are in series respectively with two auxiliary bimetallic elements or pairs of elements 54, 53 which, when heated, tend to rotate the shaft 31, but in opposite directions. Assuming that the water is below the required temperature and that the parts are in the position shown, a circuit is completed from the lead L1 through the bimetallic coil 54, electromagnet 85, contacts 82, 41 to lead L2. The reversing switch 87 is actuated and the valve 89 is opened by the motor 88 allowing steam to enter and heat the water. The coil 54 is heated by the current passing through it, and causes the contact 41 to move from the contact 82 thus breaking the circuit through the thermal coil 54 and the electromagnet 85 and stopping the motor. The coil 54 now cools down and will again cause the contact 41 to engage the contact 82 and the valve 89 to be opened still wider bv the motor 88 unless by this time the main thermal coil 30 has reached a temperature sufficient to hold the contacts 41 and 82 apart. Assuming the latter to be the case, the temperature of the water will continue to rise through the steam entering it until the main thermal coil 30 causes the contact 41 to engage the contact, thereby actuating the reversing switch 87 causing the motor to close, the valve 89. The auxiliary coil 53 now comes into action and acts similarly to separate the contacts 41, 79 and stop the motor before the main coil 30, acting alone, would have done so. The contacts 79 and 82 are constituted bv the cores of electromagnets in series with the coils 95, 85 respectively to give a quick action to the contact 41. The end of the coil 30 not connected to the shaft is adapted to be adjustably rotated for temperature setting.

Title: Molybdenum recovery process
Inventor: ERHARD ALBERT EDWARD
IPC: C22B34/34
Filed: 1966-06-27
Abstract: Ores or ore concentrates containing molybdenum as alkaline earth or magnesium molybdates are subjected to sulphating conditions with a source of sulphate at least stoichiometrically equivalent to the alkaline earth or magnesium molybdate prior to or simultaneously with the conventional extraction with a gaseous mixture containing hydrogen chloride and oxygen at a temperature sufficient to volatilize the molybdenum chlorides and oxychlorides formed and which are subsequently condensed.  The treatment with the gaseous mixture is preferably carried out at above 250 DEG  C.  Suitable sources of sulphate are sulphuric acid, ionizable sulphates such as sodium, potassium, lithium and ferric sulphates, and a mixture of sulphur dioxide and air.  In general the sulphate source is intimately mixed with the molybdenum source prior to the treatment with hydrogen chloride and oxygen but the sulphating and extraction processes may be simultaneously carried out by treating the molybdenum source with a mixture of hydrogen chloride, sulphur dioxide and air.
