Title: Improvements in modulation for instrument landing systems
IPC: H03C1/52
Filed: 1967-12-29
Abstract: 1,142,420. Amplitude modulation. CSFCOMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 29 Dec., 1967 [5 Jan., 1967], No. 59178/67. Heading H3R. A modulating system comprises two resistance networks Z 1  and Z 2 , Fig. 4, in series with respective resistances R 1  and R 2  and supplied with the carrier signal e at terminal 3, the reactances being varied by control signals applied to terminals 6 and 7 and the output being derived between points 1 and 2. Preferably, the resistance networks comprise a varactor diode (C 1  or C 2 ) arranged as shown with two inductances l and L and it is shown that if the two control signals are proportional to /sin # Ft/ and /sin (#/4 - # Ft)/ respectively, the output is equivalent to amplitude modulation by a signal sin 2 # Ft; signals equivalent to modulation by cos 2 # Ft are produced if the control signals are proportional to /cos # Ft/ and /cos (#/4 - # Ft)/, so that two circuits as in Fig. 4 supplied with these four control signals will produce the two pairs of sidebands required in an ILS system. The control signals may be derived by frequency division from a pulse generator (G, Fig. 6, not shown) to derive four square waves in correct phase and with an amplitude controlled by the carrier signal via a peak rectifier (X). Each square wave is filtered to produce a sine wave which is rectified to produce the required constant polarity signal. This signal may form one input to a difference amplifier (A, Fig. 5, not shown), the other input of which is the actual signal at the corresponding terminal 1 or 2, the output of the amplifier being combined with a D.C. bias and fed to its associated varactor diode.

Abstract: 1338422 Cooling pipe-lines KERNFORSCHUNGSANLAGE JULICH GmbH 14 Dec 1970 [15 Dec 1969 (2)] 59369/70 Headings H1A and A4D In an electric power transmission system one or more power input stations are linked to one or more output stations by lines each comprising an electrical conductor and a pipe through which is passed coolant for cooling the conductor, the transmission lines being connected so as to form a pathway for the coolant in the system, the pathway including a closed circuit e.g. B, E, G, H, C, B. The pathway may also include open-ended spurs e.g. F, J, K, coolant being pumped along the spur from a supply tank at one end to a tank at the other. The coolant may be returned to the supply tank by road or rail tankers or the flow may be periodically reversed. In the form of Fig. 1 the transmission line comprises conductors 7 mounted within a pipe 6 through which flows liquid helium. Another pipe 4 carries a coolant such as liquid nitrogen to cool radiation shield 2 surrounding the pipe 6. Shield 2 is surrounded by other radiation shields 3 of super-insulation material and the space between shield 2 and outer casing 1 is evacuated. In another form, Fig. 3, the pipe 4 surrounds the pipe 6 and, with shield 2, provides a concentric channel for coolant. The conductors 7 may be arranged in separate pipes 6 within the tube 4. The transmission line has refrigeration units 2, Fig. 6, at intervals, each comprising a compressor 5 and heat-exchangers 3 and 4. Coolant leaves the unit in two conduits 6 and 7 at different temperatures. The colder flows via conduits 7 to cool the conductors, while the warmer flows via conduits 7 to cool the shield 1. In a modification Fig. 7 (not shown) the coolant stream for the conductors is divided on leaving the refrigeration unit so that it flows in at least one of the conduits in a direction opposite to the flow in the other conduits. Similarly the shield may be cooled by coolant flowing in opposite directions in two conduits.

Title: Method of and means for generating hydro-electric power
IPC: F03B11/00
Filed: 1978-10-25
Abstract: A turbo-generating system in which the turbine and associated feed means are located beneath the surface of a body of water. Valve means operatively associated with such feed means provide metered flow of water to the turbine from the surrounding body of water which itself acts as a forebay for the system. A reservoir is disposed subjacent the exit port of the turbine in water-tight communication therewith. The reservoir is of sufficient capacity to permit free flow of water from the turbine while concurrently allowing for the build up within the reservoir of a head of water sufficient to effect discharge of water from the system through means disposed in flow communication with the reservoir. The discharge means is oriented in a plane generally parallel to the immediately overlying water surface and extends from the reservoir a distance sufficient to permit discharge of water from the system against a head less than that used to drive the turbine by utilizing the curvature of the earth to reduce the head against which the water must be discharged from the system. <IMAGE>
