Abstract: This invention relates to a system for maintaining a constant picture aspect ratio on a television display device. There is provided a television display device having a line scan circuit (10,12,14,20) and a field scan circuit (24,26,28,30,32) in which the amplitude of the line scan signal is selectively variable and the field scan circuit (24,26,28,30,32) is controlled in dependence upon the amplitude of the line scan signal such that the amplitude of the two scan signals remain in a predetermined ratio to one another. A respective detector (20,32) is included in each scan circuit in order to provide D.C. output signals proportional to the respective scan currents. The two D.C. signals are applied to a differential amplifier (22) which serves as a comparator and error signal amplifier. Output from the differential amplifier (22) is connected to a voltage controlled monostable (34) the duty ratio which is variable in dependence upon the error signal derived from the differential amplifier (22). The monostable multivibrator (34) controls a switchable attenuator (26) included in the field scan circuit (24,26,28,30,32) such that when the amplitude of the line scan signal is changed to vary the width of the picture, the field scan signal is automatically controlled so as to maintain the aspect ratio constant. A constant frequency signal having for example a frequency equal to eight times the line frequency is applied to the trigger input (36) of the monostable multivibrator (34). <IMAGE>

Abstract: A cooled rotor aerofoil blade (10) having a closed cycle cooling system containing sodium comprises an aerofoil cross-section portion (11) and a root portion (12) which are interconnected by a shank portion (13). The shank portion encloses two pairs of chambers (14) one chamber (16) of each pair being interconnected with the other chamber (17) via a heat exchanger (20) provided on the upstream face of the shank portion (13). The aerofoil cross-section portion (11) encloses a plurality of length-wise extending passages (26) which interconnect the two pairs of chambers (14) within the shank portion (13) with a further chamber (27) provided within the tip (28) of the aerofoil cross-section portion. A closed cycle cooling system is thus defined which contains sodium as the cooling medium. In operation, sodium contained within the passages (26) is vapourised, passes down a central passage into the chambers (17) and thence into the heat exchanger (20) where it condenses. The condensed sodium is then centrifugally pumped into the shank chambers (16) and back into the passages (26). Thus the aerofoil portion (11) is cooled, the waste heat being disposed of by way of the heat exchanger (20). <IMAGE>

Patent GB-2143403-A (GB)
Title: Telecommunication exchange
Inventor: KELLY MICHAEL BERNARD
IPC: H04Q3/545
Filed: 1983-07-15
Abstract: In a telecommunication system with a number of units (Ula-Una, Ulb-Unb) for control purposes and also for subscriber facilities, each such unit is duplicated, as is the system controller (SCa, Scb). There are two local area networks (1,3), each of which interconnects one system controller and one unit of each pair of units. When one network is to be isolated, e.g. for servicing or when a fault occurs, its controller detects that condition, and isolates that network by relay circuitry in the termination (T2, T3) of the bus. Another version of the system uses local area networks of the closed ring type. In certain cases the units, etc., may be triplicated.
