Title: Improvements in or relating to television and like systems
IPC: H04N5/40
Filed: 1935-12-02
Abstract: 466,715. Valve modulating circuits. BAIRD TELEVISION, Ltd., and WHITE, G. W. Dec. 2, 1935, No. 33297. [Class 40 (v)] Two frequencies, such as picture and synchronizing signals, are modulated upon a carrier at the same stage of amplification by applying the signals to separate electrodes of a multigrid valve, or valves in push-pull. Two valves 1, connected in push-pull are supplied with carrier through the transformer 2. Picture signals are applied to the control grids from source 3 and synchronizing signals to the screen grids from source 4. A condenser 5, of low impedance at the carrier frequency but high impedance at the synchronizing frequency, connects the screen grids to the cathodes. The modulated carrier is passed by transformer 6 to the aerial 7 or further amplifiers. The arrangement shown in the Figure may be modified by the use of other multi-electrode valves and by the injection of one of the signals by anode modulation. Specification 460,222 is referred to.

Title: Improvements in staple driving machines
IPC: B25C5/02
Filed: 1933-07-03
Abstract: 421,717. Stapling. GOODMAN, L. L., and VANDERVIEREN, F. A. J., (trading as GOODMAN & VANDERVIEREN), 22a, Unwin Road, Peckham, London. July 3, 1933, No. 33321/34. Divided out of 421,344. [Class 89 (iii)] In a stapling-tool of the kind in which the driving stroke of the plunger is effected by a spring adapted to be stressed by a hand lever, the plunger f carries pins m which project through slots n in the head d of the tool and engage slots in bell-crank levers o pivoted to the head at p. The other limbs of the levers o carry shoulders q and studs u engaged in V-shaped slots t formed in the forked ends r<1> of a lever r pivoted at s. In the normal position with the body of the tool raised from the base as shown, the ends r<1> rest on the shoulders q and the studs u are in the vertical limbs of the slots t. When pressure is applied to the lever r, the body of the tool moves down to engage the work, and the levers o turn about their pivots p to raise the plunger f against its spring w. Finally, the ends r<1> slip off the shoulders q and the studs u ride into the horizontal portions of the slots t, releasing the plunger. In dealing with thick work, it may be impossible to depress the lever r far enough to release the trip device q, u. In such a case, a lever x is depressed while pressure on the lever r is main. tained. The nose x<2> of the lever then engages and raises the ends r<1> sufficiently to allow the studs u to enter the horizontal portions of the slots t.

Filed: 1959-10-01
Abstract: 970, 534. Sorting by gauging. ENGLISH ELECTRIC CO. Ltd. Sept. 30, 1960 [Oct. 1, 1959], No. 33371/59. Heading G1M. [Also in Division H3] Sheets of material cut from strip 10 by a flying shear 13 are sorted according to thickness and according to whether they possess any visible faults. A flying micrometer 11 measures the strip and if any is off-gauge a signal is sent to a transfer device 19 which stores the signal until that particular part of the strip has reached the shear 13. The signal is then passed through a bi-stable flip flop 20 to an AND gate 21, which also receives signals from a photo-electric device 22 when the trailing ends of newly cut sheets pass it. When two signals are received simultaneously by the gate 21 a signal is passed on to a second transfer device 25 which stores the signal until the trailing end of the corresponding sheet has almost reached a position 27, and then the signal is passed to the inputs of a number of AND gates 33. A further signal is produced whenever a photo-electric device 28 responds to the presence of a sheet, and this signal is passed to the input of one of the gates 33 by the connections A to J, these connections being energized in turn as successive sheets pass by the device 28. If at any time a signal indicating a fault in the strip is present at the input to the gates 33, produced either by the micrometer 11 or by a workman using a device 44, that one which is energized will pass a signal on to a further bistable flip-flop 35, which will energize a corresponding AND gate 36. This gate, however, will remain unresponsive until it receives a "sheet present" signal produced by a photo-electric device 41 situated just before the sorting unit 17. If one of these gates becomes responsive a signal is passed to a solenoid 18 operating a deflector 17. The photo-electric devices 28, 41 are spaced apart a distance greater than the length of the longest sheet to be cut, and the number of parallel paths between the units 33, 35 and 36 exceeds the largest number of sheets that may lie between the devices 28, 41. Means are described for resetting the flipflops.

Abstract: 521,560. Printing telegraph apparatus. CREED & CO., Ltd., THOMPSON, A. E., and SALMON, R. D. Nov. 18, 1938, No. 33586. [Class 40 (iii)] A combined transmitting and receiving step-by-step printing telegraph apparatus is provided with a send-receive switch which automatically connects the transmitting apparatus to a line at the expiry of a delay period after the commencement of the actuation oi said transmitter, and automatically changes the switch over to the receiving apparatus when the transmission is concluded. As shown, the transmitting apparatus is of the kind described in Specifications 490,404 and 502,521 and comprises keys K with bell cranks KA, KB which when depressed set projections SP to determine the signal and depress a bar LB for locking the keyboard and transmitting a deflection to a lever DL serving to rock a detent DLL off an intermediate shaft DCS. The shaft DCS then rotates and after a predetermined degree of rotation releases a signal transmitting shaft TCS. Now according to the invention, a send-receive switch MC is controlled by a four-armed lever FAL co-operating with cams SRC, TRC on the shafts DCS, TCS and with a delay device of the kind described in Specification 490,413, comprising a ratchet DRW geared to an escapement DEW. Normally switch MC is against "receive" contact RC. When a transmitter key K is depressed, the shafts DCS, TCS rotate, and after a given delay cam SRC throws switch MC over to "send" contact SC, cam TRC holds switch in that position, and delay device DRW retards the return of the switch after the completion of the transmitted signal.

Abstract: 1362913 Feeding webs M KURODA 20 July 1972 [21 July 1971 5 Feb 1972] 33969/72 Heading B8R An apparatus for laterally stretching and registering a moving web 11, Fig. 1, of a textile fabric comprises a pair of stretching devices 10R, 10L disposed slidably and adjustably on a carriage 16 and controlled as regards deflection of rollers 12R, 13R and 12L, 13L about an axis Z with respect to an axis X speed and of rotation to effect lateral displacement of the web for transfer registering, by a respective feeler ring 91 pivoting between three effective positions to close electrical contacts which connect the roller drive motor 64, Fig. 5, to high, normal and slow speed voltage supplies to effect the necessary degree of stretching and/or registering. Each device 10R, 10L consists of a pair of stretching rollers 70, 71 driven by a motor 81 and a pair of nip rollers 12R, 13R and 12L, 13L driven by the motor 64 of a speed predetermined by the feeler rings 91. The feeler rings 91 can occupy nine different permutatable positions and produce a corresponding permutation of closed contacts in an electric control circuit the permutation permitting the devices 10R, 10L to be moved relative to each other when driven by a motor 120 in consequence of variation of web width and fast deflection of the devices 10R, 10L between the indicated angular (theta 1, theta 2) positions by a respective pneumatic cylinder 42 on actuation of an electromagnetic valve 103 connected to the control circuit whose contacts are operated by the pivotable feeler ring 91. The latter deflection of the devices 10R, 10L is brought about when, e.g. the device 10L cannot restore the web to its mean registering path and its lateral pull on the web is assisted by deflecting the device 10R from its extremely effective angular position (theta 1) to the lesser effective angular position (theta 2).

Abstract: 1283305 Threading prior to piecing up MAREMONT CORP 14 July 1970 [1 Aug 1969] 34070/70 Heading DID When an ends-down occurs in a spinning frame a carriage (20) Fig. 1 (not shown) stops adjacent the appropriate delivery and a sliding sub-carriage 30 mounted thereon is lowered until an arm 29 engages the ring rail (17) and supports the sub-carriage 30 thereon. A disc (24) then engages the spindle (11) and frictionally drives it in a reverse direction to unwind a length of yarn which is drawn into a suction head 22 until it activates a photoelectric cell to cease the drive to the disc (24) and allow a winding rotation of the spindle (11) and hence the bobbin (11') of from to 2 to 5 turns which brings the yarn to a horizontal disposition. Meanwhile a slidable plate 32 is moved leftwardly by a spring 41, when allowed by an actuator 53, which also raises lever 45 by engagement with cam means 36. A wire like member 50 engages the spinning ring (16) and an air blast through nozzle 48 propels the traveller (15) into engagement with member 50. Spindle (11) is now held stationary and the plate 32 is retracted by actuator 53. This lowers lever 45 and thus a yarn depressor 47 which draws the yarn down over the spinning ring (16) giving the yam an inclination to the horizontal of 10‹-20‹. Also member 50 disengages the traveller. Plate 32 is now moved slightly to the left to nip the yarn against the ring (16) by means of depressor 47 and bring a member 49 into engagement with ring (16). Another air blast from nozzle 48 propels the traveller around the ring and onto the thread, a double rotation being prevented by the traveller engaging the member 49. Plate 32 is again retracted and the subcarriage 30 is elevated to transport the yarn to a piecing head (28) which rejoins the yarn ends, at which moment the disc (24) is retracted to allow the spindle (11) to again rotate freely. The disc (24), Fig. 12 (not shown) is belt driven and carries a collar (80) on its shaft (78). The collar contains a one way clutch (92) and carries an arm (70) which operates in a slot (74) to limit its movement to about 90‹. This mechanism is utilized to achieve the 2-5 winding turns of the spindle (11) mentioned above.
