In the apparatus shown for performing the method, the tar from the coal gasification retort passes through a decanter 10, for removal of water, into the centrifuge 16, a reheater 12 being provided to ensure that the tar is sufficiently fluid. The liquid phase separated passes through outlet G into a storage tank, and the solid phase is passed via a duct 18 into a heated screw mixer 24. Raw coal or coal dust is also fed into the mixer from hopper 20 to mix with the solid phase from the tar and the mixture thus obtained is discharged into receptacle 26. The product may be used for further treatments, or recycled into the retort, or briquetted.

Title: Improvements in or relating to phase-alternating-line colour television transmissionsystems
IPC: H04N11/16
Filed: 1965-01-12
Abstract: 1,049,316. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 12, 1965 [Jan. 15, 1964], No. 1367/65. Heading H4F. A phase-alternating line (PAL) colour television system, in which there is transmitted a luminance signal on a main carrier wave and two colour signals in phase quadrature on a sub-carrier wave with one of the signals subjected to phase reversal in the alternate lines, is characterized in that the two colour signals are red and blue colour difference signals with the red colour difference signal subjected to phase reversal and that the sub-carrier signal is transmitted with asymmetrical side-bands for both colour difference signals. It is demonstrated that it is particularly suitable for use with receivers employing one-gun cathoderay tubes since it is readily converted into dotsequential form by simple circuits (see below). A transmitter is described for producing the signal in which a first matrix produces I and Q signals in accordance with the N.T.S.C. standards which are limited in bandwidth to 1À5 and 0À5 mc./sec. respectively. A second matrix then forms the red and blue colour difference signals from the I and Q signals whereby they each include components up to 1À5 mc./sec. The sub-carrier, after modulation, is restricted by filter to a lower side-band of 1À5 mc./sec. and an upper side-band of 0À5 mc./ sec. In a receiver. Fig. 4, the sub-carrier signal is converted to dot-sequential form by modulation in stages 4 and 7 with signals at twice sub-carrier frequency, the sub-carrier being applied to stage 4 during odd lines, when the red colour difference signal is in one phase, and to stage 7 during even lines, when the signal is in the reverse phase, by means of a switch 2. It is shown that the phases of the signals at twice sub-carrier frequency may be selected so that the dot-sequential signals which are produced by the two stages are in phase and may be combined directly. Differences in amplitude are allowed for by potentiometer network 38, 39. The signals may be combined electrically by a circuit including a delay line 6 and adder 43, or optically in the cathode-ray tube display. Conversion of the luminance signal (Y) to a monochrome signal (M) is effected in the customary manner. A modified receiver, Fig. 5 (not shown), uses only a single modulator stage for production of the dot sequential signal. The sub-carrier is applied continuously to the stage whilst the two signals at twice sub-carrier frequency and different phase are applied to the stage alternately at line rate by a first diode switch. A second diode switch controls a potentiometer in the output to modify the amplitude of alternate signals. The transmitted signal is also suitable for use with threegun cathode-ray tube receivers where demodulation of the sub-carrier is desired to obtain R-Y and B-Y directly. With a signal according to the invention, switching of the sub-carrier phase is only required for one (R-Y) synchronous demodulators.

Title: Improvements in electric time switches
Inventor: HORSTMANN FREDERICK OTTO
IPC: G04C23/34
Filed: 1957-01-15
Abstract: 817,409. Time switches; switches held set and freed mechanically. HORSTMANN GEAR CO. Ltd. Jan. 1, 1958 [Jan. 15, 1957], No. 1497/57. Class 38 (5). A switch comprises a synchronous motor 5 driving through reduction gearing an eccentric 14<SP>1</SP> which reciprocates a pawl 16 to rotate a ratchet-wheel 20 anti-clockwise. Wheel 20 carries a planet gear 27 engaging sun-wheels 28, 29 having different numbers of teeth. The wheel 28 is fixed and clockwise motion thus imparted to wheel 29 rotates a dial plate 36 once in 24 hours. Tappet discs 40 are frictionally engaged with plate 36 by means of a pivotable clamping arm 41 and respectively carry an " off " pin 44 and an " on " pin 43<SP>1</SP> which rotate staggered three-pointed starwheels 51 and 52 respectively, alternately to open and close switch contacts 68, 69 by a geartrain 53, 58, 59 and cams 62, 63. Mounted in front of cams 62, 63 is a disc 65 carrying " ON " and " OFF " markings visible through a window in a plate 72, the cover 2 being wholly or partly transparent. Connection to the motor and switch contacts is made by pins such as 70<SP>1</SP>, 85, 86 at the rear of the case and provision is made for fuses, such as 92. A manual control 73<SP>1</SP> may be rotated to cause a cam 75 to engage spring blade 66 (carrying the contact 68) and close the switch. At the same time a signal arm 77 with an " on " indication covers the indicator disc 65. Should this manual control be left on, subsequent normal clockwise operation of the cams 62, 63 to the " on " condition causes an arm 64<SP>1</SP> to engage a lever 73<SP>11</SP> and return the manual control to the " off " position shown. In a modification (not shown) the manual control is replaced by over-riding automatic mechanism to set the switch to " on " or " off " on one or more days of the week. An extra tappet is provided behind dial plate 36 (at a greater radius than pins 43<SP>1</SP>, 44) to rotate a sevenpointed star-wheel through one revolution per week. Pegs may be inserted in selected holes of seven tapped holes in the star-wheel to engage a lever pivoted on pin 80 and turn an insulating plate pivoted on pin 74. This plate has two threaded holes so arranged that a peg inserted in one hole will move switch spring 66 to close the contacts 68, 69, or if inserted in the other hole will move spring 67 to hold the contacts open. Specifications 329,633, 331,083, [both in Class 38 (v)], 373,554 and 500,670 are referred to.

Abstract: 579,410. Tricing gear. GRAY, W. T., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 25, 1940, No. 1552. [Classes 78 (iv) and 78 (v)] [Also in Group XXXII] Means for facilitating the connection of a lifting hook to a floating load which is subject to wave action comprises a spring drum 6 located in, and forming part of the mass of, a ponder ball. A tricing rope 7, fixed at 6g to the drum 6, winds on and off a helical groove 6b, and after passing through a transversely movable carriage 14 and over a guide pulley 15, is attached to a coupling member 9. This consists of a coneended bar 9 in slot 9b in which is pivoted a pair of arms 9d biassed outward by a spring 9g acting through a rod 9f carrying toggles 9e. A lanyard 23 reaching down to the floating load is attached to a lever 21 which, when pulled about its pivot, draws down the rod 9f and retracts the arms 9d to enable them to pass through a base ring 20. The operator standing on the load can then seize the hook, which has been lowered to his proximity by the crane driver, and attach it to the load while the driver raises the main part of the ponder ball thus unwinding the tricing rope 7 off the drum 6. A convenient opportunity is then seized for lowering the ponder ball and re-attaching the part 9. Alternatively an automatic retraction effected by the lifting load may be employed, and this is done by a pawl 12 biassed by a spring 12d toward the middle axis of the drum so as to bear on a smooth rim 11b. Toward the end of the unwinding of the rope 7 the carriage 14 strikes a finger 12h on the pawl 12 and forces the pawl on to a ratchet wheel 11a, where it locks the drum with every fall of the load and shortens the rope 7 with every rise, thus gradually bringing the drum casing and the coupler 9 together. When coupled the cone 9a forces up the ring 20 and through spring-pressed rods 17 lifts the pawl 12 to allow its spring 12d to shift it back on to the rim 11b. Four helical springs are provided side-by-side in the drum, the two outer having their centres attached to the drum and the two inner their centres attached to a fixed drum shaft. The outside ends of all springs are fixed to a floating cross-bar movable radially in the drum. The convolutions of the middle springs are reversed relative to the outer springs. In a modification the pawl 12 may be removed automatically from the teeth 11a when most of the rope 7 is off, and a further ratchet and pawl provided operating in the reverse direction, so that some of the rope may be pulled off the drum and the latter held until the lifting hook is grasped and engaged, a lanyard then releasing the second pawl which remains out of engagement until re-set by hand.

Abstract: 813,248. Thermal regenerators, GENERAL MOTORS CORPORATION. Jan. 16, 1957 [Jan. 16, 1956], No. 1629/57. Class 64(1) A thermal regenerator comprises an annular matrix 11 rotatably supported within a housing 10 and extending through on each side of a diaphragm 12 dividing the housing into chambers for the respective heat exchanging fluids one of which is at a higher pressure than the other, the matrix supports being so located that differential fluid pressure on the matrix urges it against the supports and at the same time relative expansion between the matrix and the housing may take place. In the form shown two similar matrices are rotatably mounted on a common axis, one on each side of a gas turbine engine 13. Air from the compressor 14 flows into a chamber 16 and is heated in passing radially through the matrix to a chamber 17 from which the heated air passes to combustion chambers 18. Exhaust gases from the turbine are directed through a diffuser 22 into a space 23 from whence they flow radially through the matrix to an exhaust outlet 26. Floatably mounted seals 77 extending across each matrix and resiliently mounted rim seals extending around the periphery of each matrix are provided to prevent co-mingling of the fluids, the seals being rubbing seals made e.g. of graphite. The seals 77 are held in proper alignment by means of rollers 110 which ride on tracks 32 on the periphery of the matrix. When the matrix is rotating the differential gas pressures act to urge it against supporting rollers 37, 38 mounted on the housing. When the matrix is stationary additional support is provided by the outer portion of seal 77. Specifications 813,247 [Group XII], 813,249 and 813,250 are referred to.
