Title: Improvements in frequency-dividing circuits
IPC: H03K5/00
Filed: 1949-02-10
Abstract: 660,675. Pulse generating circuits. MURPHY RADIO, Ltd., DAVIES, S. N., and HUMPHREY, K. G. Feb. 10, 1950 [Feb. 10, 1949], No. 3690/49. Class 40 (vi). The synchronizing pulses for a multivibrator are applied across a resistor which is connected in parallel with a cathode resistor in each valve of the multivibrator through a rectifier which conducts when the associated valve is passing current. The Figure shows a multivibrator used as a frequency divider, in which the positive-going pulses which are to be divided are applied across resistor 7. Diodes 8 conduct only when the associated valve is passing current when the synchronizing pulses appear across the anode load and are thus applied to the grid circuit of the other valve which is non-conducting at that instant. Both change-over points of the multivibrator are thus triggered, and the division ratio is unaffected by small drifts in the frequency of the incoming pulses. The diodes 8 only conduct when the amplitude of the input pulses is equal to or less than the value of cathode bias of the associated valve. The stability of the circuit is thus less affected by changes in amplitude of the input pulses or by changes in the H.T. supply or in the valve characteristic. If, for example, the H.T. supply voltage increases the reduction in frequency of the multivibrator which would normally occur is offset by the increased amplitude of synchronizing signal which is applied to each valve as a result of the increase in cathode bias voltage.

Filed: 1928-02-09
Abstract: 285,038. Metallbank und Metallurgische Ges. Akt.-Ges. Feb. 9, 1927, [Convention date]. Oils, recovering; fats and fatty oils, oxidized.- Gasolene is adsorbed from natural gas, and oils are oxidized by air or oxygen by a process in which the velocity of the ascending gas current is adjusted to retain the adsorbent or oil in suspension until the reaction is completed, and is them increased, in a pulsatory manner if desired, to drive the material out of the reaction chamber. The oil is separated from the gas in known manner. The tower in which the process is conducted may advantageously be flared or coned outwardly in the upward direction so that the velocity of a current of gas introduced at the lower end diminishes upwards. In this arrangement the particles need not be uniform in dimensions as they descend to points in the tower at which the gas velocity is sufficient to retain them in suspension. Two such towers may be used in conjunction, the gas being diverted from one to' the other when the action has been completed to allow the residual material to settle down and be withdrawn. A suitable construction of tower is shown in the figure combined with a cyclone separator E. According i,o the Specification as open to inspection under Sect. 91 (3) (a) the velocity of the gas current may be adjusted so that the transfer of material from the reaction chamber is continuous. This subject-matter does not appear in the Specification as accepted.
