Title: Improvements in or relating to television relay systems
Inventor: FULLER DENNIS QUINTRELL
IPC: H04B3/04
Filed: 1953-05-05
Abstract: 759,023. Distributing television. PYE, Ltd. May 5, 1954 [May 5, 1953], No. 12453/53. Class 40 (4). [Also in Group XL (b)] In a television relay system the video signal is modulated at approximately equal amplitudes on two separate carrier frequencies, which are separated by a difference frequency which is greater than the highest modulation frequency, to produce an upper sideband on the lower frequency and a lower sideband on the higher, which have substantial portions occupying the same frequency band. The difference frequency is selected to be equal to an odd multiple of one half of the line scan frequency or such an odd multiple plus or minus one half the frame scan frequency in order that interference arising from the overlapping sidebands have a negligible effect on the received picture. Because of the inverse frequency distortion, effects, in the cable, on the video frequencies contained in the sidebands, as shown in Fig. 3, the addition of the two sidebands in detection renders the system attenuation substantially linear as shown in Fig. 5. The video signal, which is applied to modulators 2 and 3 via a splitter stage 1 is modulated by a 4 Mc/s. oscillation in modulator 2 and by a frequency (7.25 Mc/s.) which is obtained from a mixer 6, in modulator 3. The received signals, after amplification in an amplifier 11 are rectified in a common detector 12 and applied to modulate the electron beam of a cathode-ray tube 14 through a video amplifier 13. Specification 675,887, [Group XL (b)], is referred to.

Title: Improvements relating to circulatory fluid pressure power steering mechanisms for motor vehicles
IPC: B62D5/06
Filed: 1954-05-05
Abstract: 747,309. Fluid-pressure servomotor-control systems. GENERAL MOTORS CORPORATION. May 5, 1954 [June 1, 1953], No. 13040/54. Class 135. A fluid-pressure powerassisting mechanism for a vehicle steering system comprises a piston-and-cylinder servomotor with the piston fixed to the framing of the vehicle and the cylinder surrounded by a spaced concentric casing, a control valve consisting of a regulating member and a ported casing connected between the two parts of the mechanism through which a steering effort is transmitted, and a pair of conduits in the valve casing leading to the two ends of the servomotor cylinder, one directly to the adjacent end of the cylinder and the other through the space between the cylinder and its surrounding casing. In an embodiment, the steering column acts directly on the wheels through the usual steering box, rocker arm, drag link a bell-crank, and track rods. Interposed on the junction of the drag link and one arm of the bell-crank is the stem 44 of a piston-type valve 100. The latter works in a bore in a casing which is integral with the cylinder of the power device, the cylinder sliding over a piston 22 fixed to the framing of the vehicle. The outer lands of the valve are larger in diameter than the inner lands so that the fluid pressure acting on the outer lands will assist springs 142, 144 in centring the valve. The casing is provided with pressure fluid inlet ports 122, 124, a passage 134 leading by an annular passage 70 and ports 74 to the right-hand side of the piston, a port and a passage (not shown) leading to a chamber 96 on the left-hand side of the piston, and grooves 126, 128 leading to exhaust. Abutment rings 164, 166 prevent the spring- abutment washers 106, 108 from being distorted should an excessive force be applied to the valve. The piston stem passes out of the cylinder through a bushing and a low pressure seal 78. To protect the seal against the high pressures used, any fluid passing the bushing can flow into an annular chamber 72 surrounding the cylinder, through a passage (not shown) to a chamber 148 at the end of the valve, and, past a non-return valve 152, into the cylinder chamber to the left of the piston. In a modification, the track rods are directly pivoted on the cylinder. Specification 724,411 is referred to.
