Title: Improvements in volume control circuit arrangements
IPC: H03G1/04
Filed: 1939-11-21
Abstract: 536,035. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and ZEPLER, E. E. Nov. 21, 1939, No. 30525. [Class 40 (v)] In a radio receiver comprising at least two valve amplifier stages, common control means are provided for subjecting said stages to volume control together with means whereby on operation of said volume control means in a sense to reduce gain, the gain of one stage is maintained substantially constant until the gain of the other stage is reduced to a predetermined extent. In Fig. 1 V1 and V2 are H.F. and I.F. amplifiers respectively. Negative bias from a potentiometer R2 is applied directly to the grid of V2, and through a dry-plate rectifier I to the grid of V1. As the slider of potentiometer R2 moves to the left, the gain of V2 is reduced linearly; while in the early stages the gain of V1 is substantially unaffected until the resistance I decreases to reduce the gain of V2 at an increasing rate. The manually controlled slider may be replaced by an automatically variable potential applied across R2.

Title: Improvements in or relating to time period devices
IPC: H03L1/02
Filed: 1928-10-22
Abstract: 324,343. Wright, G. M. Oct. 22, 1928. Vacuum apparatus, arrangements of. - An alternating current of constant frequency for use in picture telegraphy, transmitted radio wave lengths, frequency standards, &c., is obtained by means of two time period elements' whose frequencies at a given temperature are inversely proportional to their temperature coefficients so that their difference frequency is unaffected by changes in frequency of the individual time period elements due to changes in temperature. In applying the invention to the scanning mechanism of picture telegraph apparatus, two tuning forks are employed as time period elements each fork being maintained in vibration by a thermionic valve circuit and producing a pulsating or alternating current of its own frequency. The two currents are superimposed to produce a beat frequency which is unaffected by temperature variations and is used (after amplification) for energizing the synchronous motor of the scanning mechanism. In place of tuning forks, other time period elements such as balance wheels, vibratory rods, crystals, &c. may be used.

Filed: 1959-09-15
Abstract: 865,416. Photo-electric control systems. KLOCKNER-WERKE A.G. Sept. 15, 1959 [Sept. 16, 1958], No. 31463/59. Class 40(3) [Also in Group XXII] A device for winding strip under tension into coils includes a mandrel, driven by an electric motor, on to which the strip is to be wound, a plurality of guide rollers adapted to be applied to and withdrawn from the surface of the strip around the mandrel, guide roller moving means and means actuated from the load current of said motor for energizing said guide roller moving means to cause automatic withdrawal of said guide rollers on a predetermined value of load current being reached. Hot or warm steel strip B is fed by rollers U1, U2 to a rotated mandrel H on to which it is wound. Guide rollers F1, F2, F3, F4 are applied, at the commencement of the winding, to press the strip B on to the mandrel H. As soon as the strip is gripped by the mandrel H, the consequent sudden increase in load on its electric driving motor M causes a surge of current through a primary winding N of a transformer T and a consequent voltage surge in its secondary winding S to trigger an amplifier and thyratron V and energize a relay R1 to actuate means to withdraw the guide rollers F1-F4 from the strip being wound. As soon as the end of the hot strip passes a photo-electric cell P, sensitive to infra-red radiation, a relay R2 is de-energized and causes the rollers F1-F4 to be reapplied to the strip. The application of the guide rollers F1-F4 at the beginning of the winding operation can be controlled similarly by the same or another photo-electric cell which causes the guide rollers to be applied as soon as the leading edge of the strip passes underneath.
