Patent GB-1096731-A (GB)
Title: Improvements in addition agent containing vanadium carbide
IPC: C01B31/30
Filed: 1965-01-26
Abstract: A vanadium carbide material is prepared by compacting finely divided V2O3 with carbon which is at least the stoichiometric amount to form V2C but not more than 110% of this amount, and heating the compact material under conditions below atmospheric pressure to cause reaction between the V2O3 and the C and completing the reaction at a temperature of 1200 DEG  C. to 1400 DEG  C. and a pressure of 300 microns of Hg or less.  If desired the reaction product may be contacted with nitrogen gas before it cools below 1000 DEG  C., the nitrogen being in an amount sufficient to convert the V2C in the reaction product to V2CN.  In modifications of the above process, metallic iron or iron oxide may be added to the V2O3/C mixture, in the latter case sufficient C being used to reduce the Fe2O3 to iron. Both of the products of these reactions may be nitrided as above.  A preferred material consists of vanadium, carbon, and 2-10% iron, the material being at least 80% in the form of combined vanadium and carbon and containing less than 2% oxygen, the predominant proportion of combined vanadium being in the form of V2C, the atomic ratio of V:C being in the range 1.49 to 2.42.  In the nitrided form, the ratio V:C:N is 1.49 to 2.42:1:0.35 to 1.20.

Title: An electronic overload protection device incorporating a variable electronic delay
IPC: H02H3/093
Filed: 1954-02-06
Abstract: 739,413. Protective cut-out arrangements. GOODALL, J. S. H., and CHAPMAN, G. S. Feb. 6, 1954, No. 3534/54. Class 38 (5). In an electronic-type protective device giving a calibrated time-delayed protection for small overloads, the values of the overloads are set on calibrated potentiometers which control the positive potentials applied to the control grids of multi-electrode, high-vacuum valves. Initially, in the arrangement shown, the heaters of the valves V1 ... V4 are energized by a transformer T2 which also applies a standing bias to the pentode V1 and indicator valve V2 by means of rectifier X4 and smoothing network C4, R10, C3. In addition a condenser C5 is charged from the mains supply through contacts S2 and a rectifier X3 so as to apply a biasing potential to pentode V4. A lamp N2 indicates that the arrangement is inoperative. On closing an operating switch S8 high tension is applied to the valves through rectifier X5 and smoothing network C7, T3, C6. The diode V3 then conducts and energizes relay L3 to change over contacts S4 to extinguish lamp N2 and complete the circuit for the contactor closing coil L5 which closes contacts S9, S10. The lamp N3 indicates the closing of the contactor and the valves V1, V2 and V4 remain inoperative. When current flows in the protected circuit the voltage across the secondary winding of a current transformer T1 is applied across resistors R3, R4 after rectification in a voltage doubling circuit C1, C2, X1, X2. This voltage opposes the standing bias voltage and when the load current reaches an overload value determined by the setting of resistor R3, valve V1 becomes conductive. Relay L2 is energized and at contacts S2 disconnects the condenser C5 from the supply and at contacts S3 connects the condenser to resistors R1, R2. After a time delay determined by the setting of the resistors the condenser is discharged, valve V4 becomes conductive and relay L4 is energized to disconnect the closing coil L5 and lamp N3 at contacts S6 and to connect lamp N4 and a bell at contacts S7. Under excessive overload conditions the control grid of valve V1 becomes positive and the current in the anode circuit sufficient to energize a relay L1 which at contacts S1 causes the immediate discharge of the condenser so that the contactor is opened without delay. The valve V2 is arranged to glow at maximum brilliance as the current in the protected circuit approaches the overload value determined by the setting of the resistor R3.

Filed: 1917-03-12
Abstract: 113,682. Gill, J. F., and Chaviara, J. N. March 12, 1917. Mariners' compasses; courses, indicating.-Relates to integrating- apparatus of the kind in which a clock is provided with means for varying the period of vibration of the balance and thus the rate of the clock, such means being controlled by the instrument, the movements of which are to be integrated. The end of a second hair spring a, Fig. 1, on the balance axle d is secured to a lever b pivoted co-axially with the balance and moving between the edges of an inclined slot f formed in a plate g carried by an arbor i of the instrument. In the application to an integrating ammeter shown in Fig. 2, two such clocks are employed having co-axially arranged balances, and a plate g having two slots arranged as in Fig. 2<a> is carried by the coil l of the ammeter. The clocks drive shafts n connected by a differential gear o driving the spindle p, an index hand g moving over a scale graduated in ampere hours. Other applications are described in connexion with magnetic compasses to integrate the deviations from the course, the true course being regained by altering the steering until the index of the integrator is returned to zero. Attached to a ring s normally resting on the compass card s' is a light cylinder g formed with a double slot f extending round the whole perimeter thereof. Two clocks t operating an integrator t' are fixed to the compass bowl and controlled by the slotted cylinder, the clocks moving at the same rate when on the correct course. In setting the course a radial line on the disk s is brought to the desired point by raising the compass card through a screw v and a spring-controlled lever u, a plate v<1> of which lifts the card and brings the ring s into engagement with a friction disk y rotated through a milled head w when its shaft engages therewith. In a modification of this device, a heavy weight carried by a torsion wire and floated in mercury has secured thereto a slotted cylindrical plate controlling two clocks, the differential gear of which drives a shaft controlling a second pair of clocks. A movement proportional to the angle moved by the ships is imparted by the differential gear of the second pair of clocks to a card indicating the true direction of the ship.

Title: Process of reactivating charged adsorption media by means of scavenging vapours or gases
IPC: C01B32/336
Filed: 1928-02-06
Abstract: 285,480. Metallbank und Metallurgische Ges. Akt.-Ges. Feb. 18, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Gases, separating mixtures of.-In the removal of adsorbed substances from an adsorption medium by scavenging with another gas or vapour, the adsorption medium is charged with the scavenging agent before use. For example carbon to be used for removing benzine vapour from gases is prwiously moistened with water. Reactivation is effected by heating to set free steam as a scavenging agent. According to another example wherein the active carbon is moved through the apparatus it is brought into contact with an easily volatile gas between the adsorption and reactivation stages. This gas is adsorbed and is liberated again in the first portion of the reactivation chamber, driving before it the subsequently liberated benzine vapour which is thereby prevented from recondensing on the freshly arriving cold carbon.

A resistance, such as that of a power transmission line, is measured by connecting it in series with a low-voltage D.C. source and a standard resistance adjusting the current in a separate measuring circuit comprising a second low-voltage D.C. source, another standard resistance, and a calibrated potentiometer slide wire until the voltage drops across the two standard resistances are equal, and then adjusting the slider on the slide wire until the voltage at the slider is equal to the voltage drop in the unknown resistance. The remote end 1a of the conductor 1 to be measured is connected to the remote ends of two other phase conductors 2, 3 by links 4, 5. The connection between the link 5 and the conductor 1 is made at a point PI near the end la. The near end 2b of the conductor 2 is earthed and connected, through a tuned parallel circuit 6 for rejecting induced A.C. voltages, and an ammeter 7, to one pole of a 4-volt battery 8, the other pole of which is connected to the commoned ends of a number of standard resistances 11. The free end 11b of a chosen one of these is connected to the near end 1b of the conductor 1. A separate measuring circuit comprises a 4-volt battery 14, a standard resistance 15 of the order of 2 ohms, a potentiometer 16, 16a, having a range-change portion 16 consisting of a tapped resistance and a calibrated slide-wire portion 16a, and a variable resistance 17. A galvanometer 18 in series with a tuned rejector circuit 21 for rejecting any remaining A.C. voltage, is connected by two two-position two-pole switches 19, 20 in alternative " set " and " test " positions. In the lower or " set " position of the switches 19, 20 the galvanometer circuit is connected between a point 11a on the resistance 11 and one end of the resistance 15, the other ends of these two resistances being connected together. The resistance 17 is then adjusted to give zero deflection on the galvanometer, indicating that the voltage drops across the standard resistances 11, 15 are equal. The switches 19, 20 are then thrown to the upper or " test " position in which the galvanometer circuit is connected between a potential point P2 on the conductor 1 near the end 1b and a point on the resistance 16, the potential point P1 on the conductor 1 being connected to the slider 16b, which is adjusted until balance is obtained. In a modification the far ends of the conductors 1, 2, 3 are connected together and the test connections are made to the near ends of two of them so that the resistance of the two conductors in series is measured. By measuring all the conductors in pairs, the resistance of each conductor may be obtained.
