Title: Photo-electric device
IPC: H01J40/06
Filed: 1944-03-14
Abstract: 594,945. Photo-electric cells and indicating systems. MARCONI'S WIRELESS TELEGRAPH CO.; Ltd. March 14, 1944, No. 4770. Convention date, March 26, 1942. [Classes 39 (i) and 40 (iii)] A photo - electric device includes a photo-sensitive mosaic consisting of elements arranged in one plane and divided into several groups each connected together and a light permeable anode situated in register with the mosaic and parallel thereto. In the example shown two groups 3 and 5 are connected to a bridge form of circuit, the indicating circuit 21 and 23 including a condenser 19 so that it is only actuated by fluctuations and not by steady current. In apparatus for detecting movement of objects an image is projected on the screen and, when it moves across the groups, fluctuations and thus indications are produced. If the screen is formed of strips increasing in width from one side to the other fluctuations indicate movement in one direction by variation in their frequency. By using two such mosaics with strips at right angles movement of the object can be plotted, for example on a cathode ray oscilloscope fed with D.C. deflecting voltages derived from frequency discriminators connected to the mosaics.

Title: An improved process for preparing amines of petroleum hydrocarbons
IPC: C07C209/08
Filed: 1939-02-15
Abstract: 525,147. Amines. VEREINIGTE GLANZSTOFF-FABRIKEN AKT.-GES. Feb. 15, 1939, No. 4956. Convention date, March 1, 1938. [Classes 2 (iii) and 15 (ii)] Amines of petroleum hydrocarbons are made by treating mineral oils, particularly petroleum with chlorine at temperatures below 40 ‹C. and causing ammonia to act on the chlorination products under pressure and at raised temperatures in the presence of indifferent solvents, e.g. methyl alcohol or acetone, which are capable of dissolving ammonia and chlorinated petroleum. The amount of chlorine taken up in the chlorination step may vary up to 100 per cent. of the weight of petroleum. In an example, American petroleum is chlorinated while cooling, washed with water and dilute soda solution, and the chlorinated product, containing about 19 per cent. of chlorine, is heated in an autoclave with alcoholic ammonia solution. The products may be converted into water-soluble salts which are wetting agents and may be added to sulphuric acid spinning baths for viscose. Reference has been directed by the Comptroller to Specification 339,962 [Class 2 (ii)].

Title: Improvements in electrical transmission systems
IPC: H04B3/20
Filed: 1929-02-14
Abstract: 329,298. Standard Telephones & Cables, Ltd., Marriage, W. F., and Thomas, P. R. Feb. 14, 1929. Repeating and amplifying systems.- In echosuppressors of the kind applying paralyzing grid bias to normally operative amplifiers and in which the hang-over time. of the suppressor is determined by the duration of discharge of a condenser over a resistance, the coudenser is charged under a constant potential difference in spite of variations in the energy level of the signals, by three vacuum tubes in cascade the first being an amplifier and the other two arranged as rectifiers. The suppressor operating for transmission west over line 2, 2<1> comprises an input transformer 7 and amplifying valve 8 which is followed by two rectifying valves 10, 13. The valve 10, which is coupled to valve 8 by a transformer 9, is biassed to operate as an anode bend rectifier and is coupled by a transformer 12 to valve 13 operating as a diode rectifier. The plates of the valves 8 and 10 are fed from a common battery through a choke 17 and resistance 11 respectively, and the DO component of the output of valve 10 produces a fall in the voltage applied to its plate, and therefore a decrease in its amplification, dependent on the, value of the input current and of resistance 11. By adjusting the value of the resistance, the amplification of valve 10 may be maintained constant so that a steady A.C. component of its output is applied to rectifier 13 and a steady voltage drop occurs across the resistance 14 in the output of valve 13. The resistance 14, shunted by a condenser, is placed in the input circuit of an amplifier in the circuit for transmission east over line 1, 1<1> and is arranged so that a paralyzing potential is applied to that amplifier. The suppressor is adjusted so that it does not operate due to line noise &c., but that a slight increase in the energy level causes the voltage, across resistance 14 to increase suddenly to a steady state.
