Abstract: 1,235,344. Colour television. HARRIES ELECTRONICS CORP. 2 Dec., 1969 [10 Dec., 1968], No. 58580/68. Heading H4F. [Also in Division G2] In a colour television system, three tubes 2, 4 and one obscured, produce coloured component images at phosphor screens 10 and the images are projected by concave reflectors 12 through stops 14 to meniscus lenses 16 and are then superimposed on the viewing screen 8. The tubes are arranged symmetrically about the axis of the viewing screen and to prevent keystone distortion a transparent facetted composite corrector plate 6 is positioned as shown. The plate has three limbs and each limb intercepts a projected light beam. Each limb comprises a series of parallel strip facets arranged at right angles to the line which bisects the limb and passes through the central axis of the composite plate 6, and one surface of each strip varies in curvature from point to point in a continuous manner whilst there exist abrupt discontinuities of slope at the junctions between strips. The gradients of, and discontinuities between, the facets are carefully designed to eliminate keystone distortion. A four tube, four limbed corrector plate system is also described.

Title: Improvements in and relating to television receiving apparatus
Inventor: MUDD LIONEL THOMAS
IPC: H04N5/62
Filed: 1969-12-03
Abstract: 1,224,979. Radio receiving circuits. COMMUNICATIONS PATENTS Ltd. 3 Dec., 1969, No. 58993/69. Heading H3Q. The invention relates to television receivers of the intercarrier sound type, used for receiving wired broadcasts. Such a receiver may be of the type used for receiving radiated signals, comprising aerial socket 5, a frequencychanger 7, wideband I.F. amplifier 9 and video detector 10. The receiver is adapted for receiving wired television signals by means of an auxiliary frequency changer 1 connectible by means of ganged switches 6 to the alternative lines 2-4. This arrangement is unsuitable as it stands for receiving frequency-modulated sound signals unaccompanied by video signals, transmitted by wire, since the video carrier required for producing the intercarrier I.F. at detector 10 is then absent. According to the invention, to permit of reception of such sound signals, suitable I.F. carrier waves may be injected into the I.F. amplifier 9 from an oscillator 24, by means of switch 25. The oscillator 24 may be tuned for reception of a number of sound signals on different frequencies by means of presettable variable capacitors 26-28, or a single varactor diode may be used. The arrangement may also be used with receivers adapted to receive wired broadcasts directly, in which case the frequency changers 1, 7 are omitted and the wired signals are injected directly into the amplifier 9 from terminals 30.

Abstract: 1321393 Exhaust gas cleaner K AOI 29 Dec 1971 [29 Dec 1970 (3) 30 Jan 1971 (2) 1 April 1971] 60550/71 Heading BIT [Also in Division F1] I.C. engine exhaust gas cleaning apparatus comprises an exhaust gas inlet leading to a cylindrical expansion chamber of greater crosssectional area than the inlet and having an end face opposite the inlet formed with a plurality of apertures and a cleaning arrangement down stream of the expansion chamber, which consists of a plurality of axially-spaced cleaning stages each comprising a condensation chamber defined by a multi-apertured adiabatic expansion plate and a multi-apertured ventilating partition plate and a collecting chamber filled with a mass of filter material; a conduit means passing through the cleaning arrangement and communicating through a plurality of apertures with each cleaning stage so that gas passing through the said end face passes either to the first cleaning stage or into the conduit. Exhaust gas enters a separating chamber 3 by a tangential inlet pipe 2 and is swirled around the chamber. The expansion of the gases causes condensation of water vapour, in which noxious components of the gas become dissolved and the water droplets and carbon particles are centrifuged to the outside of the chamber. The partly purified gas flows through the divergent duct. 5 and again expands on entering the chamber 6. The end wall of the chamber is formed by a multi-apertured adiabatic expansion plate 7 through which the gas passes into a condensation chamber 10, and hence through a multi-apertured ventilating partition plate 9 into a collecting chamber 12 filled with a least resistant filter material 11. Some of the gas flows along the central conduit, and having passed through the plate 7a can then pass radially outwardly through apertures in the wall of the conduit. The gas passes through two further cleaning stages, under the last of which is a drip tray 19, from which drain holes 20 lead into a tank 21, having a draw-off valve 22. The cleaned gas impinges on a baffle plate 15 before leaving the apparatus by an outlet 17. In a modification Fig. 4 (not shown) the central conduit decreases in diameter at the beginning of each cleaning stage. In a second modification the outer casing is frusto-conical and increases in diameter in the direction of gas flow. In this embodiment the central conduit increases in diameter at the beginning of each cleaning stage. In a third modification the outer casing is frusto-conical and decreases in diameter in the direction of gas flow and the central conduit also decreases in diameter at the beginning of each cleaning stage.

Abstract: 1292125 Push-pull bulk effect oscillators WESTERN ELECTRIC CO Inc 16 Dec 1969 [20 Dec 1968] 61111/69 Heading H3T A push-pull oscillator has the cathode of one bulk effect semi-conductor device 10 connected to the anode of another bulk effect semi-conductor device 11 and to a tank circuit including in parallel a resistor 22, a capacitor 21 and an inductor 20 such that when a bias 12, 13 is applied to the other electrodes 18, 19 of the devices, the devices alternately nucleate a travelling domain. If each bias source 12, 13 is V T -V DS / 2 ,where V T  is the threshold voltage for producing a domain and V DS  is the domain sustaining voltage each device operates alternately to produce half-a-cycle of a sine-wave output (Fig. 2, not shown). If the bias sources 12, 13 are less or greater than the above voltage the domain in each device is nucleated for a less or greater time than above which results in distortion of the sine-wave output. When the bias voltages are greater the domain propagation in the two devices will overlap.

Abstract: 656,808. Control systems for discharge lamps. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Oct. 11, 1948, Nos. 26428 and 26429. Convention dates, Oct. 11, 1947 and Sept. 23, 1948. [Class 38 (iv)] Dimming of a discharge lamp is effected by two transductors, effectively in parallel with one other and providing for coarse and fine control of the lamp current, respectively. A common control member may act upon both transductors. Fig. 3 shows one such arrangement in which a lamp 1 is supplied from a source 3 through a transformer 7 and transductors 8, 9, the first of which provide for coarse control and the second for fine control. Control is effected by a single variable potentiometer 6 connected across a D.C. source 5 and having, in addition to the variable tap d, a fixed tap b. The excitation of the control winding 11 of transductor 8 is determined by tap d so long as the last lies between a and b, but rectifier 16<SP>1</SP> prevents energization of this winding when the tap is in the range b to c. In this range, however, a control winding 12 of the " fine " transductor is energized over rectifier 16 in accordance with the position of tap d and opposes a constantly energized D.C. winding 12a. In another arrangement the two transductors are controlled by ganged rheostats or potentiometers.
