Title: Improvements in or relating to electric irons
IPC: D06F75/18
Filed: 1943-06-15
Abstract: 570,409. Hand irons. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 15. 1943, No. 9561. Convention date, May 22, 1942. Addition to 557,139. [Class 138 (ii)] [Also in Group XI] In this modification of the steam iron described in the parent Specification, a single manually adjusted means sets the sole plate temperature and the rate of flow of water to the steam generating chamber. A shaft 24 in bearings 25 fixed to the top of the body chamber 15 of the iron carries a cam 59 to lift an arm 58 secured to the stem 47 of the needle valve 46 against the action of a spring 52. A second cam 29 on the shaft bears against the end of a sliding rod 30, spring-biassed upwardly, which adjusts the thermostat. The rod 30 has a adjusting screw 32 to calibrate the thermostat. A knob 23 fast on the shaft has a scale 27 and projects through an opening in the cover so as to allow the heat and damping to be set for ironing different fabrics. To allow the iron to be used " dry as well as "with steam" the arm 58 has fast to it a lever 55, Fig. 2, extending through the cover laterally, and held in one or other, position by an over centre spring 56 against pins 57. In a modification the two cams are of disc form 82, 83, Fig. 5, on a vertical spindle, with adjusting knob 87, and press arms 76 and 81 on the valve stem 69 and thermostat spindle 78 respectively against the upward thrust of their springs 75, 78. The thermostat cam 83 is in two equal parts from highest to lowest point each half turn of the knob 87 but the steam cam 82 has one half level to hold the valve shut for dry ironing, and the other half from 'highest to lowest points to give steam appropriate to the thermostat setting. To allow the valve to be shut off when necessary as when warming up, the valve stem is carried up to an external knob 74, and a spring ball and groove detent 95 holds the valve in shut or cam controlled position. A double scale on the knob 87 gives the setting for steam or dry ironing.

Title: Improvements in and relating to clamping circuits for television video signals
Inventor: SAVAGE DAVID CHRISTOPHER
IPC: H04N5/18
Filed: 1959-03-19
Abstract: 883,694. Television. BRITISH BROADCASTING CORPORATION. Feb. 26, 1960 [March 19, 1959], No. 9616/59. Class 40(3). The D.C. component of a video signal which has been transmitted through a circuit having imperfect D.C. couplings or which introduces low frequency interference is restored by means of a circuit in which a sampling stage 4 examines the level of recurring elements (the back porch in the arrangement described) to produce pulses representing the deviations of the level from a reference potential. The pulses are applied through an amplifier and inventor 6 to a further sampling stage 7 which controls the application of the peaks of the pulses to a capacitor storage circuit having a time constant (100 microseconds) of the order of the video signal recurrence interval. The resulting varying potential is then combined with the original video signal at the input of a cathode follower 2 which feeds the sampling stage and is effective to restore the D.C. component. The sampling circuits in stages 4 and 7 comprise four-diode gates, Figs. 2 and 3 (not shown), which are operated by pulses from associated phase splitters 5 and 8 respectively. Pulses to operate the phase splitters are derived from the synchronizing pulses with the original signals which are separated by a stage 11 and applied to a 2 microsecond delay line made up of sections 12 and 13. Section 13 is short-circuited whereby the reflected pulse is reversed in polarity. In response to negative synchronizing pulses of 10 microsecond duration there is produced for phase splitter 5, 4 microsecond positive pulses commencing with the trailing edges of the synchronizing pulses, and for phase splitter 8, 3.4 microsecond pulses commencing 0.3 microseconds after and terminating 0.3 microseconds before the pulses for phase splitter 5. Where the invention is employed with an N.T.S.C. type colour signal sub-carrier, trap 10 and a further trap at the input of sampling stage 4 are included. Pulse amplifier 6 is A.C. coupled.

Abstract: 149,721. Stones, A. J. April 17, 1919. Air, treating; ventilating pipes, arrangements of.-In heating and ventilating systems of the type in which exterior air is heated by a chimney flue and distributed through a building, vitiated air being removed by the suction of the fire, the cold air is led into and up the chimney flue and then down to the bottom, either alongside the flue or by a separate conduit away from it. In the system shown in the Figure, the usual chimney flue 1 is closed at top and bottom and the gases from the fire or range 2 pass up a pipe 3 within the flue. Air enters the lower end of a pipe 5 which terminates near the top of the flue, the air being warmed on descending the flue. The heated air is distributed to the various rooms by a system of pipes 7, 9 with openings 10 controlled by dampers 8; it may be supplied through radiators or imitation stoves. Foul air is withdrawn through a system of piping 11 connected to the ash-pit of the stove 2. The pipe 3 may have external flanges to give greater heating surface, and baffles may be provided in the flue 1 to make the descending air take a circuitous course. An electric fan may be placed at the bottom of the pipe 5, or elsewhere, to assist the circulation The air may be passed through filtering and purifying means, such as moistened coke and slacked lime. The pipe 5 may be replaced by one of inverted U-form arranged in the flue 1.

Title: Improvements in or relating to cathode ray tube protective circuits
IPC: H04N3/20
Filed: 1961-03-17
Abstract: 982,773. Cathode-ray tube circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 17, 1961 [March 22, 1960], No. 9838/61. Heading H4T. In a circuit arrangement for diminishing beam current in a cathode-ray tube (C.R.T.) when the line and frame scanning fields collapse, thereby preventing burning of the screen, two gas discharge devices are used the circuit junction of which is connected to the C.R.T. cathode. In one embodiment neon, krypton or argon devices 23, 24 (which may be constructed in one envelope) are connected via brightness control 27 to normal television receiver H.T. supply V b , derived from a selenium rectifier, and to video output stage 19; to C.R.T. cathode 22; and to a D.C. voltage V c  derived by rectification and smoothing from positive-going flyback pulses 29 tapped off line output transformer 4. Under normal operating conditions the gas discharge devices are struck. Assume that the receiver is switched off; the time constant of network 30, 31 is made such that fall of V c  keeps step with the slow decrease of pulse 29 amplitude and after a time V c  falls to a value whereby tubes 23, 24 are extinguished. In the meantime supply V b  has almost collapsed, so that C.R.T. grid 20 is above earth potential and the ensuing gridcathode bias cuts off the C.R.T. beam. In a second embodiment, the video signal is applied to the C.R.T. cathode via a capacitor bridging tube 24 and voltage V c  is taken, without the need for additional rectifier 28, from the line output transformer circuit; and a voltage intermediate V c  and V b  is used to supply a first accelerating C.R.T. anode. To obviate screen burning when voltage V c  persists due to failure or removal of the line output valve, the supply voltage for the frame sawtooth generator is taken from the same point as the V c  source, Fig. 2 (not shown). To prevent screen burning if a normally-provided plug and socket connection between the deflection coils and their feed circuits is broken with the receiver " on," the supply voltage for the line output stage is taken via an additional connection on the plug and socket. To obviate screen burning due to the discharge of the stray capacitance of the C.R.T. cathode under abnormal operating conditions when the cathode pin is touched, an insulating hood may be provided on the C.R.T. base.
