Title: Improvements in or relating to amplifying or detecting circuits employing a screenedvalve
IPC: H01J19/82
Filed: 1931-04-17
Abstract: 380,827. Thermionic valves. GRAMOPHONE CO., Ltd., Hayes,and BULL, C. S., 33, Micawber Avenue, Hillingdon, both in Middlesex. April 17, 1931, No. 11489. Drawings to Specification. [Class 39 (i).] In circuits for amplifying radio and audio frequencies or for detecting and particularly in power output stages, distortion due to secondary emission from the anode of a screenedgrid valve when the anode voltage swings below the screen-grid voltage is avoided by biasing this grid to a positive potential with respect to the cathode equal to or less than the critical anode-cathode potential, usually 30-40 volts, below which the liberation of secondary electrons from the anode is negligible. As normal screen-grid valves so operated have a very high impedance, the electrodes are constructed and arranged to give an impedance of 500,000 ohms or less, preferably 50000-100,000 ohms, under the operating conditions, details of a valve with control and screen grids of wider mesh than usual being specified. The anode-cathode impedance may be less than 200,000 ohms with positive potentials of 120 volts and 40 volts on the anode and screen grid respectively, and with 1 volt negative on the control grid. Resistance or transformer couplings may be used.

Title: Testing Equipment and method for Equalizing the Feed Rates at various parts of a Running Length or Lengths of Material
IPC: D04B15/48
Filed: 1967-03-13
Abstract: 1,172,158. Speed indicators. AMBASSADES. March 13, 1967 [March 11, 1966], No.11669/67. Heading G1K. [Also in Division D1] Apparatus for testing the speed of runs of the same or different materials in a knitting machine so that the feedrates can be equalized comprises a tachometer having a tensiometer on either side. The tachometer comprises a pulley clutched to a drive motor. In use the clutch is disengaged and the pulley brought into contact with the running yarn at an arbitrary first knitting station. The motor is then run at the same rate as the pulley and the rate and tensions noted. The apparatus is then applied to the remaining running yarns in turn with the pulley rotated by the motor at the rate first noted. If the feedrate at any station is not the same as at the first station, as evidenced by slippage of the yarn on the pulley and a corresponding difference in tension noted at the tensiometers, the stitch cam is adjusted so that tensiometer readings are equal. The feedrates are now at the desired value.
Patent GB-504156-A (GB)
Title: Improvements in or relating to communication systems particularly printing telegraph systems
IPC: H04L12/14
Filed: 1938-04-19
Abstract: 504,156. Type-printing telegraphy. STEVENS, A. H. (International Business Machines Corporation) April 19, 1938, No. 11740. [Class 40 (iii)] Apparatus for attachment to a printing telegraph transmitter comprises means for recording time indications, obtained, from a timing mechanism at the transmitter, at both the transmitter and receiver. In the case of a transmitter operated by a motor-running at known speed, this speed is used as a means of obtaining the time indications. Depression of a timing key TK, Fig. 1, completes a circuit through magnets 39 and 49. Energization of the magnet 49 attracts a T-shaped arm 46, against the action of returning springs 47a, 47b, which tilts a lever 44a carrying a detent 43 by engaging one or other of two pins 44b, 44c, Fig. 1a, carried by it. The arm 46 engages these pins alternately by being brought to a central position by a leaf spring 45b, Fig. 1b, as it returns. Raising of the detent 43 allows a clutch member 42, under the action of a spring 20d, to engage a member 41 on a shaft 20a driven by the constant speed motor. This rotation is communicated by reduction gearing 51a to mechanism 50, of the type used in revolution counters, which moves arms 61, 63 over a number of circularly arranged contacts to indicate minutes and tenths. Energization of the magnet 39, simultaneously with that of the magnet 49, moves a detent 36 which allows a friction driven cam 33a to make a single revolution. This cam has a single lobe which successively closes contacts 34, 35 to complete circuits through the moving arms 61, 63 to certain, 12, 15, of a number of magnets which cause the depression of numeral keys forming part of the telegraph transmitter proper appropriate to the position of the arms 61, 63. Thus, on initial depression of the timing key TK, figures representing minutes and tenths are printed at the transmitter and a corresponding signal is transmitted to the receiver. When the message is completed, the timing key is again depressed, energization of the magnet 49 throws the clutch out of operation, so stopping the timing device, and the cam 33a causes the time indication to be recorded at the transmitter and receiver. By subtraction of the appropriate time indications, the time taken for transmission of one or a number of messages is computed.
