Abstract: 790,346. Gas turbine plant. GENERAL MOTORS CORPORATION. May 23, 1956 [May 25, 1955], No. 15996/56. Class 110 (3). [Also in Group XXVII] A power plant comprising a free-piston engine feeding a gas turbine and one or more accessory pumps for the engine, has an electric motor operable independently of the engine and turbine and an over-running clutch arranged between the pumps and turbine the arrangement being such that the pumps are driven by the electric motor when its effective speed is greater than that of the turbine, and the clutch overruns. A free-piston engine 10 of the two-stroke diesel type supplies combustion gas to a useful power turbine 40. A by-pass valve 48 allows the engine to operate without the turbine. A fuel pump 49 supplies fuel to the engine injectors 36. A water pump 52 circulates cooling water through a water tank and cooler 53, the compressor inlet valve cooling chamber 54 and the cylinder cooling jacket 56. An oil pump 74 circulates cooling oil through the interior of the engine pistons 12 and oil tank 77. The pumps are driven by a common power shaft 102 which is connected to a constant speed electric motor 104 by gearing 100, 101 and an over-running clutch 106, and to turbine 40 by a shaft 108 and an over-running clutch 110. The shaft 102 is driven by the turbine 40 when the turbine has a higher effective speed than the motor 104 and is driven by the motor 104 when the motor has a higher effective speed than the turbine. To start the plant the motor 104 is energized and drives the pumps. When the turbine reaches its governed speed the clutch 110 engages and the clutch 106 overruns. The clutch 106 may be dispensed with in which case, the motor 104 acts as low power generator when the effective speed of the turbine is greater than that of the motor.

Abstract: 805,037. Colour television. CHROMATIC TELEVISION LABORATORIES Inc. June 7, 1955 [June 7, 1954], No. 16342/55. Class 40 (3). [Also in Group XL (a)] A colour-television cathode-ray receiving tube designed to work on the N.T.S.C. system comprises a single gun with a cathode 102, Fig. 1, to which the chrominance signal is applied, and a control grid 104 to which the luminance signal is applied, a multi-dot luminescent screen 114 and two sets of local deflecting wires 116, 1161 and 120, 120<SP>1</SP> designed to be fed in quadrature so as to rotate the beam in a circle during the time of one colour cycle. As shown in Fig. 2, alternate sets of wires 116, 1161 and 120, 1201 are connected together and rotate the beam in circles of opposite hand in successive mesh area. The disposition of luminescent sub-areas consisting of red, blue and green is such that the bisectors of the sub-areas are at angles substantially equal to the phase angles between the phases of the colour component at the moments when the amplitude of the component is proportional to the signals determining the primary colours to be produced. Preferably, as shown, the coated areas are of 60 degrees angle and non- coated white areas are left between to reduce colour contamination. In the circuit shown in Fig. 1, the demodulator 2 produces (1) the luminance component which is applied through low-pass filter 8, delay line 10 and amplifier 14 to the control grid 104 (2) the chrominance component, modulated on a sub-carrier, which is applied through band-pass filter 16, modulator 50 and amplifier 18 to the cathode 102. Modulator 50 is an amplifier of variable gain over the sub-carrier cycle, so as to present the colour amplitudes at their correct values. It is fed with a sub-carrier signal generated by generator 20 which also energizes wires 116, 116<SP>1</SP>, 120, 120<SP>1</SP>. A simple sine-wave variation of gain is stated to be adequate but a more correct law of variation involving a D.C. component and a phase-shifted sine-wave is discussed. Graphs are given of the variation of each colour component over the sub-carrier cycle. Specifications 721,523 and 757,071, [both in Group XL (a)], are referred to.
