Abstract: 797,554. Radio receiving circuits. COLLINS RADIO CO. Oct. 4, 1955 [Feb. 10, 1955], No. 28255/55. Classes 40 (5) and 40 (6). In a detector circuit detection is performed by a diode 17, the load of which comprises a pair of resistors R1, R2 in series. A first audio output is obtained over resistor 23 and blocking condenser 24, carrier frequencies being removed by means of a series-tuned shunt circuit 27. A second, noise-limited output is obtained via resistor 20, series diode 28 and blocking condenser 32, carrier frequencies being removed by shunt condenser 25. The diode 28 is normally conductive, its cathode being held at a negative potential derived from the mean carrier level over resistors R3, R4 and condenser 29 which serves to remove both carrier and audio frequencies. The peak outward modulation level at which diode 28 becomes non-conductive is determined by resistors R1-R4; an expression for this is given in the Specification. The circuit also provides delayed automatic gain control, by means of diode 34, the cathode of which is coupled to the join of resistors R3, R4. The anode is connected to earth via resistor 36, across which the gain control potential appears and delay is obtained by returning the circuit of the detector 17 to a point of positive potential, provided by a potentiometer 18, 19 across the H.T. supply.

Title: Process for the production of depolarising compositions from native manganese dioxide, e.g. pyrolusite
IPC: H01M4/50
Filed: 1935-10-14
Abstract: Depolarizing compositions are obtained from native manganese dioxide or pyrolusite by roasting the mineral at say 650--680 DEG  C. to convert a portion, say 20--25 per cent of the MnO2 into Mn2O3, dissolving out the Mn2O3 by acids or acid salts, reprecipitating the Mn2O3 by alkali on to the undissolved mineral residue, and finally subjecting the mixture of oxides to oxidation, as by means of permanganates or manganates.  Solution of the Mn2O3 may be effected by a mineral acid such as sulphuric acid or by an organic acid such as acetic acid, and the alkaline sludges formed in the oxidation of organic substances with permanganate in alkaline solution may be used for its reprecipitation.  The results of tests using the raw mineral alone, and the raw mineral with 10 and 30 per cent of the product of the invention in a salammoniac cell are given.  It is stated that the manganese hydroxides obtained in oxidation reactions such as the oxidation of toluene sulphonamide or toluene to benzoic acid with permanganate yield satisfactory depolarizing compositions.

Abstract: 727,724. Pulse storing circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 3, 1953 (Dec. 4, 1951], No. 28455/51. Addition to 645,691. Class 40 (6). [Also in Group XIX] In a cathode-ray tube store of the type described in the parent Specification, in which the beam releases secondary electrons from the screen to set up one or other of two charge patterns and the beam subsequently explores the pattern to develop signals in a pick-up plate which are used to regenerate the patterns, a circuit is arranged to interrupt regeneration and to modify the scanning process to prevent complete erasure of the charge pattern. The invention is described as applied to Specification 705,482. Negative-going dot pulses are applied to the cathode of diode 29 to cut off normally conducting valve 30, the anode potential being caught at + 50 volts due to diode 31 conducting. The anode potential is applied through a cathode follower (not shown) to the C.R.T. grid. In order to write a dash, a long pulse is fed in over the WRITE terminal, the beam being switched off temporarily by a meditation pulse applied to the cathode of diode 31. During the succeeding scan, a pulse is generated in the pick-up plate which causes a negative pulse to appear on the grid of valve 34 and hence on grid of valve 30. This pulse is prolonged by the dash pulse applied over diode 35 and thus a dash pulse, interrupted by the meditation pulse is fed to the C.R.T. During a non-erasing reading, negative-going dot pulses lower the potential of the grid of valve 37 to remove the clamp in the control grid of valve 30. The rest level of the cathode of diode 31 is lowered to 30 volts to cause the C.R.T. beam to take up a suitable intensity on the recurrence of a pulse. When regeneration is required, the grid potential of valve 37 is lowered to bias off diode 38, the rest level of diode 31 being raised from 30 to 50 volts to increase the beam intensity on the occurrence of a pulse. The switching waveforms may be regularly recurring and a number of non-erasing scans may occur between successive regenerating scans. Instead of using a beam of reduced intensity for the non-erasing scan, the speed of scanning may be increased.
