Filed: 1924-12-18
Abstract: 226,556. Telefunken Ges. f³r Drahtlose Telegraphie. Dec. 22, 1923, [Convention date]. Transmitting systems and apparatus.-In order to prevent dangerous voltages from arising across the condenser 6 of the intermediate circuit 3 of a transmitting installation, when the aerial circuit 4 is detuned either by design or accident, the condenser 6 is bridged by a discharge gap 5. When arcing occurs, a series resistance 7 prevents the circuit 3 from oscillating. The resistance 7 is in turn bridged by a relay circuit 8. which, when energized, causes another relay 9 to throw the transmitter out of action preferably by suitably regulating the excitation circuit of the high-frequency generator 1. The circuit 3 is fed through a, static frequency converter 2 from the generator 1.

Title: Improvements in direct coupled amplifiers
Inventor: PAUL ROBERT JOHN ALEXANDER
IPC: H03F3/36
Filed: 1956-10-09
Abstract: 812,774. Valve circuits. SHORT BROS. & HARLAND Ltd. Oct. 9, 1957 [Oct. 9, 1956], No. 30801/56. Class 40 (6). A directly-coupled amplifier with negative feedback has continuous correction for drift provided by an auxiliary amplifier having its input terminal connected to one differential input terminal of the main amplifier and its output connected to the other input terminal of the main amplifier, and a subsidiary feedback path from the output of the main amplifier to the input to the auxiliary amplifier that may be disconnected by a switch. Fig. 1b shows a system comprising a main amplifier A having a gain between terminals 2, 3 of M1 and an auxiliary amplifier B having a gain of - M2. The main feedback path is via a resistor R2 so that the system can function as an adder. The subsidiary feedback path is provided via a switch S1, resistors Rz and kr, the feedback factor being selected so that the voltage at terminal 5 is independent of the signal voltage. It is shown that the effective gain of A is unchanged but the drift is reduced by a factor (k/1+k) M2, where k is the ratio of the input resistors r, kr. The capacitive feedback of Fig. 1a enables the system to integrate. The subsidiary feedback path is not shown as it is disconnected by switch S1, Fig. 1b. It is shown that the gain is - M1(1 + M2). If the drift due to B can be neglected the overall drift referred to terminal vd 4 is --, where vd is the input drift of amplifier A M alone. In Fig. 2c (not shown), a selector switch alters the input and main feedback circuit to allow the system to perform a variety of operations as described in Specification 745,660, [Group XXXVI]. In the present Specification this switch has an extra pole S1, Fig. 1b, which controls the subsidiary feedback path. The main directly coupled amplifier A, Fig. 2a (not shown), is described in Specification 745,660. Chopper modulated amplifier.-The referred input drift of the auxiliary amplifier B is made as low as 20 ÁV. by the use of the A.C. coupled circuit of Fig. 2b. The input and output are alternately earthed by a relay L1 fed from 50 c/s. supply to provide modulation and demodulation. A smoothing circuit R9, C6 and an output switch S2 are provided. Hum elimination.-50 c/s. pick-up at the grid of V1a is minimized by two capacitors C7, C8 and a potentiometer VR1 connected across the centre-tapped heater supply.

Abstract: 936,920. Processing radio-active waste. M. W. KELLOG CO. Sept. 9, 1960 [Sept. 10, 1959], No. 31108/60. Class 39 (4). A solid mixture containing a radio-active component is converted to a water-unleachable solid by heating the mixture with a metal oxide and a polyvalent element which has an exothermic heat of oxide formation higher than that of the metal oxide. The solid radio-active mixture may be obtained by evaporation of liquid radio-active waste material. Preferred metal oxides are the higher oxides of Fe, Pb, Mn, Cu, and Ni, but reference is also made to oxides of Cr, V, Sr, Cs, Ti, W, Ta, Sb, Bi, Ce, Sn, Co, and Mo. The metal oxide may be present in the radio-active waste or may be added as the oxide or as a salt (e.g. an oxalate, acetate, carbonate, or nitrate) which decomposes to the oxide. The preferred elements to react with these oxides are silicon, aluminium, and zirconium, other suitable elements being P, Pu, Ta, Th, V, Mg, and Ca. Alumina and silica may also be added and these oxides become incorporated in the product. To initiate the reaction, a mixture of the powdered components is heated, for example to 700-1200 C., when an exothermic reaction takes place at high temperature, resulting in the formation of a complex rock-like product. Reactions of ferric oxide-silicon, ferric oxidemagnesia-silicon, and ferric oxide-aluminium mixtures are described. when radio-active Sr or Co is added before the reaction, tests show that the radio-activity is not leached out from the product with water. In Example 10, dried radio-active waste is mixed with Fe 3 O 4  and silicon and heated in a porcelain-lined reactor, the reactor being disposed of with the product cemented to its walls. Example 11 describes heating radio-active strontium nitrate, aluminium nitrate, aluminium powder, and titanium dioxide to form a product from which radio-active strontium cannot be leached with water.
