Title: Device intended to convert electric pulses into duration modulated pulses having steep leading edges
IPC: H03K7/08
Filed: 1952-11-07
Abstract: 733,199. Pulse modulation circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 7, 1952 [Nov. 7, 1951], No. 28127/52. Class 40 (5). In a duration or time position modulating circuit, an input pulse, Fig. 2 (a) is applied to a series inductor 2, Fig. 1, and shunt rectifier 4 through which a steady current Io, Fig. 2 (b) passes. The current through the inductor due to the pulse increases until it equals the steady current whereupon the rectifier 4 ceases to conduct and presents a high impedance so that the output terminal 3 assumes the same potential, Fig. 2 (c), as the input terminal 1. The steady current is maintained by a negative potential applied at the remote end of resistor 6 and is modulated by a potential applied over transformer 16 which causes the point at which the diode current, Fig. 2 (b), falls to zero to vary. The leading edge of the pulse at point 3 varies accordingly. The pulses at point 3 may be differentiated by capacitor 12, inductor 13 and rectifier 14 to produce a single short output pulse. An inductor 15 prevents loss of high frequencies due to self-capacity of transformer 16. In a modification, Fig. 3, the resistor 6 is biased from a winding on transformer 21 so that the time of occurrence of the leading edge of the output pulse is independent of input pulse amplitude. Conversion of amplitude modulated pulses to duration modulated pulses. If the steadystate current through rectifier 4 is maintained constant, variations in amplitude of the applied pulses cause the rate of rise of current in the inductor 2 to vary and thus the position of the leading edge of the output pulses.

Title: Manufacture of unsaturated hydrocarbons
IPC: C07C1/32
Filed: 1928-10-01
Abstract: 298,090. Soc. of Chemical Industry in Basle. Oct. 1, 1927, [Convention date]. Unsaturated aliphatic hydrocarbons are obtained by reaction between methyl alcohol and a carbide of an alkaline earth metal at ordinary pressure. The acetylene liberated during the reaction may be removed continuously from the reaction vessel or may be caused to react with compounds present in the reaction vessel by the use of catalysts, which may include carbides, metals, metal oxides, metal hydroxides, metal salts, carbon, silicates or other materials resistant to a high temperature. The vapours of methyl alcohol may be passed through the carbide at 200‹-300‹ C., and the product then treated for separation of the desired compounds either directly or after the catalytic treatment. The uncondensed gases may be allowed to escape or may be recirculated through the system until they are all converted into high-boiling unsaturated compounds. The temperatures may vary within somewhat wide limits. The reaction vessel is preferably provided with means for automatically introducing the carbide and continuously freeing the latter from the oxide formed during the reaction; the carbide may advantageously be agitated gently. The reaction is preferably conducted with the exclusion of air or oxygen. When the acetylene and uncondensed reaction gases are allowed to escape, the main products of the reaction are dimethylacetylene and ethylacetylene, and when the gases are utilized as above described, there is obtained a whole series of unsaturated hydrocarbons, ranging in boiling point from 4‹ C. to over 100‹ C., and containing ethylacetylene, dimethylacetylene, isoprene, dimethylallene and higher homologues or polymers up to cinene. The proportion of higher-boiling unsaturated compounds may be increased by the use of aqueous methyl ,alcohol, thus increasing the quantity of acetylene formed, which may then be converted into higher-boiling hydrocarbons by repeated passage through the system. The condensed hydrocarbon mixture may be separated by fractional distillation or any other method of purification, e.g. washing, absorption or precipitation.

Abstract: 427,630. Television. COSSOR, Ltd., A. C., and BEDFORD, L. H., Highbury Grove, London. Oct. 13, 1933, No. 28397. [Class 40 (iii)] In order to accentuate the higher frequencies, the transmitted signal in a system using velocity-modulated scanning is derived from a voltage representing the displacement of the scanning-spot by the superposition of a voltage representing a derivative with respect to time of the displacement. The picture to be transmitted is scanned line by line by the voltages across a condenser C1, Fig. 1, which is periodically discharged by a valve V2 as described in Specification 419,298. The voltage across the condenser is proportional to the displacement of the scanning-spot, and a voltage proportional to the velocity of the scanning- spot is produced by a resistance R1 in series with the condenser. At the receiver, Fig. 8, the voltage for controlling the displacement of the luminous spot is derived from the received signal by a circuit consisting of a resistance R and a condenser C with a time constant equal to that of the condenser C1 and resistance R1 at the transmitter. A resistance R1 is inserted in series with the condenser C to obtain a voltage Vi proportional to the time-derivative component of the signal which is used to modulate the intensity of the luminous spot, as described in Specification 413,401. Specifications 399,469 and 427,625 also are referred to.
