Title: Arrangement for comparing voltages
Inventor: SNIJDERS ANTONLE
IPC: H04Q1/18
Filed: 1950-10-17
Abstract: 675,926. Automatic exchange systems. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Oct. 17, 1950 [Oct. 17, 1949], No. 25318/50. Class 40 (iv). [Also in Group XXXVI] In an arrangement for comparing voltages, e.g. for use in a marker, giving a signal when a certain voltage out of a series of consecutive voltages comes into a previously fixed relation to a marking voltage, this relation exists between each voltage of the series and a marking voltage of such a value that these two voltages have a fixed sum. A marking switch MS is connected to a potentiometer R3, R4. The voltage at the contacts of a selector K to be positioned is determined by resistances R1, R2. The arms of the marker switch and selector switch are connected by two equal resistances R5, R6 so that the potential of the point n is half the sum of the voltages at the marking switch MS and the selector switch k, for example - 30 volts. The point n is connected to the control grid of a valve B1, and the control grid of a valve B2 is connected to a point m between two equal resistances R13, R14 which has potential equal to that at which the point n is to be maintained. The screen grids of the valves B1, B2 are connected crossways to taps on the anode resistances by which means a certain amplification is produced which is so chosen that if the voltage at the point n is - 31 volts valve B2 conducts and B1 does not, whilst if this voltage is - 29 volts the reverse takes place. A rectifier bridge G has its corners a, b connected to the anodes of the valves B1, B2 and its corners c, d to the control grids of two valves B3, B4, the screen grids of which are cross-coupled to the anodes. A balancing effect is thereby obtained when the control grid voltages are equal. If the potential of n equals - 30.5 volt, the potentials of p and c are equal and the valves B3, B4 alternate in conductivity. Between - 30.5 and - 29.5 volts, c is positive with respect to p and B3 is conductive and B4 non-conductive. At a voltage of - 29.5 volts the potentials of p and c are equal and above - 29.5 volts the valve B3 is non-conductive and B4 conductive. In the anode circuits of the valves B3, B4 a polarized relay T is inserted and operates only if the potential of n lies between - 30.5 and - 29.5 volts, and interrupts at its contact t the circuit of the driving magnet of the selector K. The valves B1, B2 may be dispensed with, the points a, b being connected to the points n, m, and points c, d to the control grids of the valves B3, B4. A low voltage battery is included in one of the latter connections. Specification 664,658, [Group XXXVI], is referred to.

Title: Improvements in or relating to methods of producing a radio-active chromium preparation from vanadium-containing material which also contains radio-active chromium
IPC: C01G37/00
Filed: 1953-09-17
Abstract: 744,950. Producing radio-active substances. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Sept. 17, 1953 [Sept. 20, 1952], No. 25717/53. Class 39 (4). From vanadium-containing material, after nuclear bombardment, a preparation containing radio-active chromium is obtained free from other radio-active metals by producing ferric hydroxide in an aqueous solution of the bombarded material under oxidizing alkaline conditions to precipitate other radio-active metals, leaving vanadate and chromate in solution for separation by a known method. Vanadiumiron-copper alloy is bombarded with deuterons, the resultant material dissolved in aqua regia and the solution evaporated until V 2 O 6  tends to precipitate, NaOH and H 2 O 2  then being added and the product boiled. The ferric hydroxide precipitate is filtered off, taking with it radioactive scandium, calcium, cobalt, and manganese, and copper. H 2 SO 4  added to the filtrate precipitates V  2 O 6  and the chromate is extracted into an aqueous layer by shaking the solution in a separating funnel with a liquid ester, ketone, or alcohol not miscible with water (e.g. amyl acetate) and H 2 O 2  and then with NaOH added.
