Abstract: 809,595. Colour television. MULLARD RADIO VALVE CO. Ltd. Feb. 13, 1956 [Nov. 18, 1954], No. 33435/54. Class 40 (3). In a television system, such as a colour system, wherein the transmission consists of a main signal v, v<SP>1</SP> on a main carrier V, a pair of quadrature-modulated signals c on a sub-carrier C, and a sound signal on a carrier S, a phasereference signal for demodulating the subcarrier is derived at the receiver from the difference frequency between the sound and main carriers. With signals having frequencies according to example shown, the sound carrier S appears at 3.5 Mc. after demodulation at a frequency centred on the main carrier V and after suitable selection from the modulation components is divided by 4/3 to provide a signal of 2.625 Mc. corresponding to the frequency at which the sub-carrier appears. The frequencies indicated are approximate, since, at the transmitter, the sub-carrier is arranged to be an odd multiple of half the line frequency which in turn is locked to the mains frequency. Starting with the 2.625 Mc. signal, this is multiplied by 4/3 to obtain the 3.5 Mc. for the sound carrier, and then finally the 3.5 Mc. is mixed with a 45 Mc. signal to obtain the 41.5 Mc. sound carrier for transmission. Fig. 2 (not shown), illustrates an alternative transmission signal in which the sub-carrier is located outside the band of the main signal. Specification 741,278 is referred to. Reference has been directed by the Comptroller to Specification 776,554.

Filed: 1921-12-20
Abstract: 195,138. Fairweather, H. G. C., (Aktiebolaget Atlas Diesel). Dec. 20, 1921. Rotary and oscillating cylindrical valves. - In machines for loading ores &c. into mine trucks comprising a bucket mounted at the end of a pivoted arm which is movable in a vertical plane, the cylinder of the motor actuating the arms is vertical and is mounted to rotate about a vertical axis in the free end of an arm resting on the base of the machine, the other end of the arm being connected by a vertical pivot to the base. The arms 20 supporting the bucket 22 are mounted on the crank shaft 14 outside the crank casing 15 which is formed integral with a, cylinder 12 and a depending cylindrical member 11. The piston rod 17 is formed as a toothed rack and meshes with a toothed segment 18 on the shaft 14. The supply of pressure fluid to the motor is controlled by a rotary valve 33, Fig. 4, having an arm 34 projecting into the path of a cam 28 on the crankshaft 14 and a rope connection 42 with a handle 43. The casing 32 of the slide valve has an inlet 35, Fig. 6, for compressed air, an exhaust 36 and a passage 37 leading to the cylinder 12. The valve has two systems of passages, one comprising a narrow diametrical channel 39, Fig. 5, and the other comprising a wider diametrical channel 40 and a branch channel 41. A piston 44 is slidably but non-rotatablv mounted in an extension 33<1> of the valve 33 and is moved against the resistance of a spring 46 by compressed air admitted through the passage 45. The end of the piston rod 47 carries an angularly-shaped arm 51 which in conjunction with a spirally-shaped shoulder 54 on the casing 53 limits, the rotation of the valve, so that the position of the piston rod determines the area of the passage 40 uncovered and hence the quantity of air admitted to the cylinder 12. When the bucket 22 has been loaded, the handle 43 is moved in the direction of the arrow a, Fig. 1, until it encounters a stop 100. This action places the valve in the position shown in Fig. 4 and air is admitted through the narrow passage 39 to act on the pistons 13, 44. No movement of the piston 13 occurs but the piston 44 moves through a distance proportional to the load. The handle is now turned in the opposite direction as far as possible and air is admitted through the wider channel 40. The piston 13 moves down and the arms 20 swing upwards until the belt 57 strikes the projection 73, whereupon the material is thrown over the cylinder 12 into a truck.
