Title: Color-image-reproducing apparatus
IPC: H04N11/14
Filed: 1955-07-07
Abstract: 782,868. Television. HAZELTINE CORPORATION. July 7, 1955 [July 28, 1954], No. 19636/55. Class 40 (3). In a colour television receiver utilizing a constant luminance type of colour signal undesired luminance response to the chrominance components (due to the non-linear characteristic of the picture-reproducing tube) is minimized by converting the chrominance components into pulses which are time modulated in accordance with the variations of such components and applying these pulses to the picture-reproducing tube. As shown, the R (red), G (green) and B (blue) components, which are derived in a combining circuit 19 to which the colour difference signals from detector 20 and the 0-1 Mc/s. components of the luminance signal Y from the gamma amplifier 50 are supplied, are fed to the anodes of diodes 22, 23 and 24 respectively, the cathodes of which are driven by sawtooth signals derived from generator 25 and which have amplitudes extending over those of the R., G. and B. signals. During intervals when the amplitudes of the latter exceed that of the sawtooth signals pulses of current flow through resistors 26, 27 and 28 and the resulting voltage pulses are supplied to the cathodes of the picture reproducing tube 16 via respective limiter amplifiers 29, 30 and 31. With this arrangement modulation of the beam of tube 16 by the chrominance signals is effected at a constant amplitude level and consequently the latter signals do not contribute to the resultant luminance of the reproduced image, the highfrequency <SP>1</SP>/γ (1-3.6 Mc/s.), components of which are derived from video amplifier 15 and fed to the control grid of tube 16 in conventional manner. In addition to modulating the cathodes of tube 16 by constant amplitude timemodulated pulses representative of the chrominance components, the low-frequency (0-1 Mc/s.) components of the luminance signals which are present in the chrominance signals applied to diodes 22, 23, 24 and uncorrected for gamma (because of gamma amplifier 50) are effective to reproduce the correct low-frequency detail in the reproduced image, it being assumed that the received composite signal comprises a luminance signal which is corrected for gamma and two chrominance signals uncorrected for gamma. Specification 689,356 is referred to.

Title: Improvements in and relating to apparatus for the control of electric circuit breakers
Inventor: HEWINES EDWIN JAMES
IPC: H02H7/22
Filed: 1954-07-06
Abstract: 761,923. Protective cut-out arrangements. ENGLISH ELECTRIC CO., Ltd. July 1. 1955 [July 6, 1954], No. 19723/54. Class 38(5) In a control arrangement for an electric circuit-breaker of the type having tripping mechanism which if the circuitbreaker is closed on to a fault overrides the closing mechanism and allows the circuit-breaker to open, an electrically-aotuable means C for initiating a circuitbreaker closing operation is connected in series with a pair of normally open contacts B-3 of an "anti-hunting" relay B and with contacts A-3 of a control relay A. In Fig. 1, when a control switch CS is moved to its "close" position the control relay A is energized over contacts B-1, LS and closes contacts A-1, A-2, A-3. Relay B is now energized and opens contacts B-1 and closes contacts B-2, B-3, the last completing the circuit for the means C which may be the coil of a contactor, a closing solenoid or electrically operated blast valve. As the circuit-breaker closes, the contacts LS of a limit switch are opened to de-energize the control relay A to open contacts A-1, A-2, A-3, the coil C being de-energized but the relay B remaining energized over its contacts B-2 so long as the control switch is maintained closed. Hence if the circuitbreaker trips out before the control switch is restored, the open contacts B-1 prevent the re-energizing of the relay A when the contacts LS reclose and so prevent any further attempt at reclosing, i.e. "hunting." In a modified arrangement, Fig. 2 (not shown) the opening of the contacts of the relay A are delayed, the relay A being deenergized on the closing of the relay B. Fig. 3 (not shown) illustrates an arrangement for a circuit-breaker having independently-operated closing mechanisms for each pole. The limit switch may be provided with additional contacts to maintain the relay B energized when the circuitbreaker is closed and the control switch is restored to its "neutral" position (Figs. 4 and 5, not shown). A warning device may be controlled through further contacts on relay B and through contacts on the circuit-breaker to give warning of faulty closing or tripping.

Title: An improved process of distilling tar with the production of a greatly increased amount of liquid distillates
IPC: C10C1/04
Filed: 1937-07-16
Abstract: Tar is distilled by circulating an oxygen free gas, e.g nitrogen, carbon dioxide, coke oven gas, coal gas, supersaturated with the tar vapours, through a still, containing the tar, and a large air condenser, which is maintained at such temperature that the amount of vapours condensed therein does not relieve the supersaturation of the circulating gas.  Air may be used as the gas and is freed from oxygen by circulating the air through a charge of tar until all the oxygen is removed by oxidation of the tar, the still being then filled with a fresh charge and the circulation continued.  Fresh gas is continually pumped into and concentrated pitch removed from <PICT:0469514/III/1> <PICT:0469514/III/2> the still.  The gas may be circulated by a totally enclosed blower, fan, or compressor and a pressure is built up in the circuit.  Tar containing up to 5 per cent water may be treated by the process the water combining with constituents of the raw material.  The air condenser may be replaced by a number of smaller condensers in series.  Coke oven or gas works tar is distilled in a still S of 3000--4000 galls. capacity by circulating air therethrough and through a condenser E, divided by a partition P, by a fan F capable of circulating 2000 cubic feet of air per minute.  The condenser may be replaced by a series of condensers 1, 2, 3, 4, provided with valved conduits a, b, c, d, and with down-take pipes which cause the gas to bubble through the condensates collecting therein.

Filed: 1924-08-26
Abstract: 233,952. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). Aug. 26, 1924. Supplying consuming devices.-The current in an electric circuit such as a theatre lighting circuit is arranged to be varied at will by tapping it from a potentiometer resistance 19 which is itself tapped from another potentiometer resistance 14 connected across constant potential mains. By shifting the taps of the last mentioned resistance 14 which may be regarded as the primary potentiometer, the upper and lower limits of variation are set or preselected, and by shifting a tap of the first mentioned or secondary potentiometer 19, smooth variation is obtained between the limits. The secondary potentiometer mav be composed of two separated resistances 31<a>, 31<b> traversed by a movable bridging member 23 which moves out of contact with one resistance when approaching one of the limits. Two or more circuits, for example the circuits 5 - - 8 shown in Fig. 1, may be simultaneously controlled by simultaneously operating several secondary potentiometer taps, one in each circuit, by means of a common handle 25; separate preselection may be retained by separately operating the taps 15 - - 18 and 27 - - 30 of the primary potentiometer. In a modification shown in Fig. 2 a number of preselected variations of a single circuit is obtained by providing a corresponding number of sliding taps 34<a> - - 34f on a primary potentiometer resistance 33, and connecting them in sequence with a secondary potentiometer resistance through a group of switches 38<a> - - 38f actuated by a cam shaft; this shaft and the secondary slider 36 being driven simultaneously by a motor 39. In a further modification for use with alternating current circuits, the primary potentiometer is an autotransformer winding. The secondary potentiometer resistances may be in the form of concentric rings. In the arrangement shown the tapped off circuits are used to vary the saturation of inductive choking devices of known kind 9, Fig. 1, and 35, Fig. 2, whereby variations of current are obtained in the lighting circuits 5, 6, &c. fed from alternating current mains L<1>, L<2>.

Abstract: 816,875. Centrifugal compressors. BUCHI, A. J. July 12, 1955 [July 13, 1954], No. 20189/55. Class 110 (1). A delivery guide duct for a centrifugal compressor comprises an inlet part which receives fluid from an annular clearance around the impeller and leads directly into a straight-sided diffuser, the inlet part comprising an open channel-like section followed immediately by an enclosed section, both the open and enclosed sections being formed with a widening angle in the flow direction to transform some fluid velocity into pressure, additional to the widening of the open section necessary to allow for the increasing afflux of fluid in the direction of impeller rotation, and the widening angle being equivalent to a cone angle of 2 to 5 degrees of an equivalent truncated cone. There may be three to six delivery guide ducts. In the compressor shown, there are five delivery guide ducts 6, each comprising a curved inlet part 11, a straight-sided diffuser 13 and a curved diffuser 14, each duct discharging into a space 15 leading to a common volute 8. Each inlet part 11 comprises an open section subtending an angle # equal to 72 degrees (or 360/n degrees if there are n ducts 6), followed by a closed section 11<SP>1</SP> subtending an angle 8, which is not less than 12 degrees and in the compressor shown is equal to 28 degrees. An initial part of the inlet part 11, up to a section a<SP>1</SP>-a<SP>1</SP> and subtending an angle # of 28 degrees, widens in the radial direction only with, it may be, no diffusion, and thereafter the inlet part 11 widens in both the radial and axial directions, the cross-section gradually changing from a rectangular to a circular shape. Alternatively, the inlet part 11 widens in both directions over its entire length. The diffusion effect of the inlet part 11 is equivalent to that of a conical frustum of a height equal to that of the arcuate length of the inlet part and having a circular outlet equal in area to the circular outlet F<SP>11</SP> of the inlet part and a circular inlet equal in area to the effective inlet area Fl of the inlet part, the included angle of the conical frustum being 2 to 5 degrees.
