Title: Decoding systems for colour television receivers
IPC: H04N11/16
Filed: 1971-12-03
Abstract: 1336920 Colour television SONY CORP 3 Dec 1971 [4 Dec 1970] 56268/71 Heading H4F A PAL colour television signal demodulator comprises a one-line delay line 5 and a switch 2 operated at the end of every line period by a flipflop 6 receiving horizontal sync. pulses. The signals at terminals 7 and 14 each have constant modulation axis phases and are fed to burst gates 15, 19, the separated bursts controlling oscillators 18, 21 to provide signals in phase with the respective separated bursts. These signals are added at 28 to provide a signal in phase with the negative B-Y axis which signal is passed via a phase inverter 29 to demodulator 9. A further adder 23 receives inputs from oscillator 18 and oscillator 21 via phase inverter 24 to provide a signal in phase with the R-Y modulation axis of the signal at terminal 7, which is passed to demodulator 8. Phase control is provided by gauged amplitude controllers 22, 25, 26, 27, controllers 22 and 27 operating in the same sense which is opposite to the sense of operation of controllers 25 and 26, to produce rotation of the demodulation axes relative to the modulation axes. In an alternative embodiment (Fig. 18, not shown) the separated bursts are added after amplitude control and phase inversion, where necessary, and the resulting signals control oscillators. Demodulator 9 may receive its input from terminal 14 of switch 2 in which case amplitude controllers 22 and 26 operate in the same sense, as do controllers 25 and 27 (Fig. 17, not shown). In a further embodiment (Fig. 19, not shown), switch 2 is provided with only one output, burst gate 15 receiving signals either from this output or from band-pass amplifier 1 via a switch operated by flip-flop 6 in phase with switch 2 to pass every second received line, and burst gate 19 receiving signals from band-pass amplifier 1 via a further switch operated by flip-flop 6 in antiphase with the other two switches.

Abstract: 1372176 Electrode boiler S A WILLIAMS 29 Nov 1971 [30 Nov 1970] 56759/70 Heading H5H [Also in Division F4] In an electrode steam boiler 1, waste water containing contentrated salts is removed during a period initiated with a frequency dependent on the frequency fresh water is supplied, the latter being supplied at intervals controlled by a timing device 11 responsive to the current flow in one of the electrodes 2, 3, 4, e.g. 2. As the water level falls due to conversion to steam, the reduction in current flow in electrode 2 is sensed by coil 13 of the controller 12. At a predetermined current level, the timer 11 is energized and opens valve 15 allowing waste fluid to escape along pipe 14. After a predetermined time the valve is closed and pump P started by energizing relay 17 to supply fresh water via pipe 9. As the water rises in the boiler the current flow increase in electrode 2 is monitored by unit 12 until a predetermined value is reached when the control unit signals the timer to stop the pump. The cycle thus continues. The pipe 14 may be extended to a position below the electrodes by pipe 14a. Alternatively it may be connected to the feed pipe as shown at 14b. Specification 1,326,359 is referred to for an alternative arrangement of pipe 9.

Abstract: 1377960 Brake valves COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE 30 Dec 1971 [7 Jan 1971 2 April 1971] 60766/71 Headings F2F and F2V A relay valve is connected between a distributer (not shown) and a brake cylinder 6 via inlet 4 and outlet 5 and comprises reaction and correction pistons 13, 14 a pressure reducing valve 19, and an action piston 7 connected to a stem 12 integral with pistons 13, 14 through a double arm lever 9, 10 the effective lengths of which may be adjusted according to vehicle load. A control pressure P is passed to pipe 4 and is transmitted to a chamber 32 to act on piston 7 which through arms 9, 10 exerts an upward force on stem 12. The pressure is also passed via a pipe 28 to act on pistons 13, 14 which are of different cross-sectional area. Stem 12 is moved upwardly causing a valve member 21 of pressure reducing valve to be unseated whereby braking pressure is passed to cylinder 6 from a pressure source such as a reservoir by way of pipe 35, chamber 18 and pipes 27, 5. The brake pressure increases until the downward pressure on piston 13 in a chamber 23 connected via a throttle 26 to brake pipe 5 balances the upward biasing forces whereby stem 12 moves downwardly to seat member 21. Subsequent increases in the control pressure P result in opening and closing of valve 19 to give a braking pressure constantly proportional to pressure P. The upward force exerted on stem 12 by piston 7 is varied according to load by means of a carriage 36 to which arms 9, 10 are pivoted, the carriage being movable by a piston 41 under changes of vehicle load transmitted by way of pipe 42 to change the effective lengths of arms 9, 10. A take up device, Fig. 2 (not shown) may be provided to over-ride the pressure control until the actual brake application pressure is reached. In a further embodiment the pistons 7, 13, 16 are integral and a further piston 62, Fig. 3 (not shown) is provided which varies the control according to load via a wedge member (64). A further construction provides the pressure reducing valve coaxially with piston 7. In place of the throttle 26, a valve opening at a calibrated pressure may be used.

Abstract: 613,616. Calculating-apparatus. PRECISA AKT. - GES. RECHENMASCHINEFABRIK. June 20, 1946, No. 18508. Convention date, June 20, 1945. [Class 106 (i)] A total-taking mechanism for incorporation in a calculating machine or cash register having separate sets of totalizer wheels for positive and negative totals includes means which, if a total-taking or sub-total-taking key is depressed when the total is negative, disengage the positive totalizer wheels from racks which engage type bars and place the negative totalizer wheels in engagement therewith, and which replace the positive totalizer wheels if a key is subsequently depressed to show a positive total. A bar 4 is pivotally connected at one end 7 with a larger bar 8, at its other end 9 with a bar 10 and intermediately 6 with a bar 3 connected with total and sub-total keys. If a key is pressed and there is a positive total, the bar 3 moves to the right causing a pin 11 on the bar to move in a slot 12. If the total is nega. tive, changing of the highest denomination totalizer wheel from 0 to 9 causes a disc 20 to pivot clockwise about a pivot 21 and cover the slot 12 so that the pin 11 cannot move to the right. If a key is then pressed, the bar 3 pivots the bar 8 clockwise about a pivot 13, rotating an angle lever 24 against the action of a spring 23 and pulling down an anchor 26 so that its lower cross-arm 27 can engage a peg 38 on a lever 29. By means, not shown, a lever 30 then swings to the left pulling the anchor and rotating the lever 29 which, via a bar 34, rotates a frame 17 about axes 18 and 19, thus disengaging the positive totalizer wheels 14 from the racks 16 which operate the type bars and putting the negative totalizer wheels 15 in engagement therewith. Changing of the highest denomination totalizer wheel from 9 to 0 rotates the disc 20 to its original position so that the spring 23 rotates the bar 8 to its original position and, on pressing a key, the anchor 26 pulls the peg 33 to the left and swings the positive totalizer wheels into contact with the racks 16.

Abstract: 1,259,699. Openers; feeding fibres. CURLATOR CORP. 23 Dec., 1969 [3 Feb., 1969], No. 62586/69. Heading D1N. [Also in Divisions G3 and G4] Fibres carried by an air stream are distributed to a plurality of machines from a main trunkline 101 via a plurality of branch ducts, such as 102, the fibres being diverted into the branch duct 102 by means of a gas jet 128 disposed upstream of the branch duct and arranged to direct a jet of air against one wall of the trunkline 101. The fibres can be fed to opening, blending, cleaning, carding and random web-forming machines. As shown, an adjustable air jet 128 is arranged at an interaction chamber 120 of enlarged cross section in the trunkline 101. The fibres diverted into the branch duct 102 are collected in the trumpet shaped area between adjustable metering roll 107 and plate 108, then fed to foraminous condenser drum 100 and then to a web forming machine via roll 119, 121. The fan 105 used to generate the suction in condenser drum 100 is used to feed the air jet 128. As the fibres collect in the duct above the metering roll 107 the output of the fan 105 is reduced and less fibres are diverted into the duct 102, thereby automatically maintaining duct 102 full. The metering roll may be omitted with the trumpet shaped area being formed by the condenser drum (Fig. 11). The wall of the branch duct may be flexible to assist control of the fibre flow (Fig. 12). The fibre stream diverting jet can be arranged to divert the fibre stream into either of two secondary branch ducts upon passing a single air pulse through one of two control jets (Fig. 3). Alternatively, two fibre streams can be passed to one of two respective branch ducts depending upon whether control pulses are present at one or both of the respective control jets. (Fig. 4). The outlets can be combined to blend the output fibres. Alternatively, one fibre stream diverting jet (80 or 84) can also control a second diverting jet. The second diverting jet has a further independent control port 88, (Fig. 5).  The fibre feed to the main trunkline can be via a pneumatic conveyor (126) feeding a spiked opener (138) via a tapering hopper having vertical wall (133) moving downwardly over a section box. The fibres are blown off the opener into the main trunkline by fan (139). The return duct 140 from the main trunkline feeds into a similar hopper and brush wall opener which passes surplus fibre back to the trunkline. An electrical metering device (158) positioned upstream of both opener outlets determines the rate of feed of new fibres from the hopper feeding the opener (138).
