Title: Improvements in or relating to levelling circuits
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H04N5/217
Filed: 1951-12-08
Abstract: 733,066. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 8, 1952 [Dec. 8, 1951], No. 28811/51. Class 40 (3). In a circuit for levelling television signals, Fig. 2, generated by a pick-up tube of the cathode potential stabilized type in which the line blanking signals 7 are subject to interference by spurious oscillatory signals 5, a first circuit in the form of a " clamp " operates throughout the interval 4 and a second circuit operates during the intervals 6 and/or 7 which are free from interference to correct for undesired variations introduced in the signal level due to changes which may occur in the amplitude of the spurious signals. Intervals 7 are part of the normal blanking interval, intervals 6 may be produced by interrupting the scanning beam for brief intervals prior to the line return periods. In a first embodiment, Fig. 1, the output from pick-up tube 1 is passed through amplifier 2 and the output levelled with reference to a potential established at point 10 by a " clamp " circuit 8, 9 operated throughout the interval 4. The switch 9 preferably consists of a 4-diode switch as described in Specification 512,109. The time constant of the levelling circuit is made sufficiently large to prevent random noise from disturbing the circuit operation; a preferred value is 10 microseconds. In order to correct for changes in level imparted by changes in the amplitude of the spurious signals there is provided a further switch 11 which may be similar to switch 9 and which is brought into operation throughout the intervals 6 and/or 7 and causes a condenser 12 to develop a potential proportional to the signal level during these intervals. This potential is then applied through a D.C. amplifier 13 to modify the potential at point 10 and oppose the variations due to the spurious signals. The time constant of circuit 11, 12 is preferably of the order of a frame period. A D.C. amplifier may be arranged in the signal channel between switches 9 and 11, and this amplifier may either be additional to or replace amplifier 13. In a further embodiment, Fig. 3 (not shown), the second circuit merely comprises a " clamp " circuit operating during the intervals 6 and/or 7 and having a time constant of the order of a frame period. Specifications 449,242, 696,386 and 732,907 also are referred to

Class 64(2) [Also in Group XXXVII] A Bourdon tube 6, tube 2 and pilot bulb 1 are entirely filled with liquid, such as acetone, in the liquid lock condition at 400 pounds per square inch at 70F., so that the pressure in the system varies solely with the thermal expansion of the liquid since no vapour is present, Excess pressure in the system is relieved by a stainless steel diaphragm 5 fitting against a base 4 into which the tube 2 and Bourdon tube 6 are secured for intercommunication by means of a bore 9 which is open to the upper surface of the diaphragm. A chamber 13 for containing gas is formed against the diaphragm 5 by a dome 11 secured with the diaphragm to the base 4 so that the gas, at a pressure of 930 pounds per square inch, holds the diaphragm against the base unless overheating causes that pressure to be exceeded in the system. Securement of the parts is by silver brazing. An outer housing 16 encloses the dome 11 and its sealed filling pipe 14. In a modification, Fig. 3 (not shown), the pressure-relieving device is a tube connected to the tube 2 at one end and closed at its other end and held flat by the pressure in a chamber in which it is contained until the pressure in the system exceeds the chamber pressure. The Bourdon tube, which carries an electric contact 21 for co-operation with a fixed contact 22, is filled with metal strips to reduce its volume and the volume of the pilot bulb 1 is 90 per cent of the total volume of the system.

Abstract: 1,046,268. Venetian blinds. J. AVERY & CO. (EST. 1834) Ltd. Oct. 16, 1964 [July 23, 1963; Sept. 27, 1963], Nos. 29049/63 and 38111/63. Heading E1J. In a venetian blind raised, lowered and tilted by a reversible electrical motor 17 driving directly cord drums 13 to raise or lower the slats and a driven wheel 25 in permanent engagement with a pinion 24 on the driving shaft 11, the driven wheel 25 is clutched to the tilt shaft 12 by means of two torsion spring type clutches one or the other of which is effective to raise or lower the blind according to direction of initial movement of the motor rendering the appropriate clutch operative to couple the tilt shaft to the wheel 25. The wheel 25 integral with lateral sleeve 251, 252 (Fig. 3, not shown) is freely rotatable on tilt shaft 12 and the sleeves 251, 252 are aligned with sleeves 261 secured to the shaft 12 and having thereon a settable tilt cam 30 which screens the teeth 281 on further sleeves 28 rotatable over the sleeves 251, 252, 261 with torsion springs 271, 272 Fig. 3 (not shown) sandwiched therebetween with an interference fit on the sleeves 251, 261 and 252, 261, one end 273 of each spring being fixed to the ratchet sleeve 28, and the other end left in frictional contact with the sleeve 261. When the motor is rotated (in the forward direction) to raise or lower the blind and in the absence of tilt control the initial movement of shaft 11 loosens the torsion springs and allows wheel 25 to rotate freely on the tilt shaft 12. In the lowered and closed condition of the blind, the cam 30 is so set to release the associated pawl 29 to engage the teeth 281 of the sleeve 28 and to exert pressure on the end 273 of the enclosed spring to cause this spring to resist further winding which then opens to disconnect the drive of the wheel 25 from the tilt shaft.
