Patent GB-595138-A (GB)
Title: Improvements in television systems
IPC: H04N5/52
Filed: 1944-11-06
Abstract: 595,138. Television transmission systems; multiplex pulse signalling. GENERAL ELECTRIC CO., Ltd., ESPLEY, D. C., and WALTER, D. O. Nov. 6, 1944, No. 21756. [Classes 40 (iii) and 40 (v)] In a television transmission network comprising a carrier link, or a number of carrier links in cascade, and in which the carrier is positively modulated by the picture signals in one or more links, a control signal which is fixed in amplitude and independent of changes in the television signals is superimposed upon, and transmitted with, the television signals and is utilized to control automatically the gain at one or more points in the network. At a terminal station, the control signals are broadcast. The control signals are pulses P preferably exceeding the amplitude of the peak white signals and may be inserted in the synchronizing period S occurring in the blanking signal interval A. The control signals may be inserted at the video-frequency stage by a generator triggered by the leading edges of the synchronizing impulses or they may be inserted at carrier frequency by using a local oscillator operating at that frequency and the oscillations gated to pass to the mixing circuit only during the period of the pulses produced by the generator, or the latter may be employed to control the duration of the oscillations of the local oscillation generator. The pulses may be modulated, provided their amplitude is unaffected, for transmission of information between stations of the link system, for example by phase modulation at different frequencies associated with the various stations. Control of apparatus may be obtained by keying the characteristic frequency to operate a control circuit to produce an operating signal. As a modification, the pulse duration of the control signals may be modulated. The sound accompaniment of the television signals may be transmitted over the link network by modulating the control signals, the sound signals being extracted at the receiver of the terminal station and broadcast from its transmitter on the carrier employed for the picture signals or on a separate carrier. If more than one carrier link is employed, the signals may be transmitted from a repeater station on a frequency different from that on which they were received. Specification 587,498 is referred to.

Abstract: 1324044 Rolling mills KONINKLIJKE NEDERLANDSCHE HOOGOVENS EN STAALFABRIEKEN NV 19 April 1971 [17 Feb 1970] 22004/71 Heading B3M A cooling system for cooling a hot rolled metal strip includes a number of water boxes 1 positioned longitudinally above the strip, each box having a number of curved syphon tubes 2, 3, extending from its top, and having a stand pipe 4 at one end. The stand pipe communicates with atmosphere (or with a separate air supply) and is connected near the top 8 of the box to increase the response of the box to changes in its water supply. If the water supply to the box through a diffuser 7 is stopped, the stand pipe quickly allows air to enter the top 8 of the box and to prevent further flow of water to the tubes 2, 3. The small volume of air in the top 8 also permits the flow to be rapidly resumed. A further stand pipe (shown dotted) may be used. The box may be tilted very slightly to help air to spread evenly along the box from the stand pipe or pipes.

Title: Improvements in and relating to a nuclear installation

IPC: G21C15/12
Filed: 1967-05-16
Abstract: 1,137,298. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 16 May, 1967 [16 May, 1966], No. 22585/67. Heading G6C. A liquid metal cooled reactor is housed within a double-walled casing, small diameter conduits being disposed between the walls of the casing for circulating heating fluid. A primary coolant circuit between the casing and an intermediate heat exchanger consists of pipes which are also double-walled and inside which similar small diameter conduits are disposed. A secondary coolant circuit also of liquid metal extends between the intermediate heat exchanger and a steam generator, and the heating fluid for the casing and the pipes of the primary circuit is formed by steam taken from that raised by an auxiliary steam generator operated to start the steam generator of the secondary circuit. Small diameter conduits through which heating steam circulates are disposed against the walls of the pipes forming the secondary circuit inside a heat insulation enclosing the pipes. Instead of steam, a pressurized inert gas such as nitrogen may be used as the heating fluid, being circulated by a compressor and heated by exchange with steam raised by the auxiliary steam generator. The primary and secondary liquid metal (e.g. sodium) coolants are solid at ordinary temperatures and consequently it is necessary for the casing and coolant circuit pipes to be heated before they are filled. Similarly, it is desirable to keep the metal in the liquid state during the stoppage periods of the reactor.
