Title: Improvements in counting mechanisms
IPC: G06M1/36
Filed: 1926-10-18
Abstract: 266,632. Mills. C. K., (Binns, E. H., and Binns, R. H.). Oct. 18, 1926. Counters actuated by reciprocating - mechanism; zeroizing - mechanism; transfer mechanism; stop-mechanism. - The numeral drums 16 are frictionally engaged by winding-drums 40 supporting weighted chains 41, or by spools encircled by anchored springs, so as to be zeroized when the transfer pinions and detent &c. devices are disengaged from the drums. Pinned to the hub 17 of each drum is a disc 21, Fig. 7, provided with a circular series of holes to enable the loose numeral drum 16 after being rotarily adjusted, to be secured to the disc by means of a spring bolt 23 provided with a manipulative head 25. The disc is provided with a notch 28, Fig. 5, to co-operate with a feeler 30 fixed to a spindle 31, so that when a predetermined count has been reached this spindle turns clockwise (Fig. 2) under spring action, the movement being permitted by the feelers entering the notches 28 of all the discs 21. The zeroizing winding drums are urged by springs 43 into frictional engagement with fibre discs 44 held by lock-nuts 45. The transfer mechanism comprises a combined star wheel 56 and broad pinion 57, the former engaging a notched locking disc 47 and the latter lying in the path of a transfer arm 55 and also meshing with a spur wheel 58 on the next higher drum unit. The transfer pinion and star wheel are mounted between pins 59 on a shaft 49 capable of endwise displacement to disconnect the pinions from the spur wheels. The units drum is actuated by a pawl 13 pivoted on a reciprocating bar 10 and reverse movement of the ratchet wheel 14 is prevented by a detent 38 having a lug overlying the adjacent feeler arm 30. When the number set has been counted and the spindle 31 consequently rocks, contacts 70, 71, Fig. 11, may be closed to energize a solenoid 75 to draw the shaft 49 to the right against the action of a spring 78. This through an inclined slot and pin connection 62 rocks the spindle 31 to raise the feeler arms 30 and detent 38 and, by means of a projection 80, closes contacts 79, 81 to complete a holding circuit through the solenoid. When the drums have all reached their zero positions as determined by abutment of the heads 25 with one-way dogs 35, Fig. 2, a series of contacts 84 controlled by the dogs is closed to short-circuit the solenoid and allow the shaft 49 to return to normal position. Zeroizing may also be effected at any time by manual rocking of the lever 51.

Title: Gain control circuit for radio receivers
IPC: H03G3/22
Filed: 1944-12-29
Abstract: 589,968. Wireless receiving apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 29, 1944, No. 26119. Convention date, Dec. 30, 1943. [Class 40 (v)] In a wireless receiver, the output of the A.V.C. rectifier is connected to ground through a discharge device which is biassed to conduct only on receipt of a signal above a predetermined value. The invention is described as applied to a receiver for interrupted carrier wave telegraph signals comprising a mixer 5 fed by local oscillator 25, I.F. amplifier 8 and second detector 11. The load for the second detector comprises a resistance 17 and triode 16 in series with secondary winding 10, the output being taken from the cathode of valve 16, or from a point on resistance 17 according to the setting of switch 18. A.V.C. voltage is ta'ken from the cathode of 16 by way of short time constant circuit 23, 24 to the grids of valves 5 and 8. A triode 22 is connected between the cathode of 16 and earth, and is biassed from potentiometer 26 so as not to conduct for normal signal amplitudes. Triode 16 is less biassed, and so conducts for all but very small signals. Thus, normal signal impulses cause valve 16 to conduct and the A.V.C. line is energized to set the gain to a value which is maintained during the succeeding space period. An excessive signal such as static causes valve 22 to conduct. This not only shunts away the excessive signal thus preventing its appearance in the output, but discharges the A.V.C. circuit, thus allowing the gain to rise. Otherwise, a loud signal would set the gain to a low value which might be inadequate to reproduce a weak subsequent marking signal. The arrangement is stated to be applicable to ordinary broadcast receivers.

Abstract: 1,210,166. Feeding webs. WITTON-JAMES Ltd. 21 Aug., 1969 [31 May, 1968], No. 26198/68. Heading B8R. A reel stand 1 comprises means for supporting two or more reels (17, 19, Fig. 2, not shown) for independent rotation, in a running position R2, about a common axis between a pair of supporting arms 5 to permit webs to be drawn from the reels simultaneously, all the webs passing over a common roller 22 mounted on spring or fluidpressure loaded arms 24 which are pivoted on a shaft 25 coupled to a monitoring unit M designed to produce an output dependent upon the combined tensions in the webs; the periphery of each reel is engaged by one or more straps 26 each of which has one end fixed to an anchoring point 27 and the other end fixed to a respective cam 28 in such a manner that rotation of the cam about its axis in one direction or the other wraps or unwraps the strap 26 on the cam surface. Movement of all the cams 28 is controlled by a pneumatic cylinder 35 responsive to the output from the unit M. The cams thus provide a variable ratio between the tension applied by the cylinder 35 and that imparted by the straps 26 at the reels whereby the tensions in. the straps 26 are varied in such a sense as to maintain the web tensions constant despite differences in the reel diameters. The reel stand 1 may include a two or more armed spider so that replacement reels R1 may be brought into the running position R2, and the stand 1 may be associated with means (not shown) for severing the expiring webs and joining the ends of the new webs to the severed ends of the expiring webs when the replacement reels have been run up to the appropriate speed. The shaft (8) which carries the reels (17), (19), Fig. 3 (not shown), may be provided with means for adjusting either reel relative to the complete assembly to ensure that lateral register is maintained.
