Patent GB-2106707-A (GB)
Title: Electrodes for thermionic valves
Inventor: WATSON VICTOR LESLIE
IPC: H01J1/48
Filed: 1981-09-24
Abstract: In a large high power valve the grid may be given a black, microscopically- rough surface of pyrolytic graphite to enhance the dissipation of heat therefrom. The present invention seeks to reduce, if not eliminate, the likelihood of the graphite layer separating from the grid material by forming on the grid an intermediate layer (between grid and graphite) which is itself tightly held by the grid surface, and which has an outer surface that is microscopically rough and forms a good bond to the pyrolytic graphite deposited thereon. In particular, it provides a pyrolytic-graphite- coated electrode for use in a thermionic valve, which electrode has, between the electrode metal (21) and the pyrolytic graphite coating (23), a separately- applied intermediate layer (22) of the carbide of one or more Group IVb, Vb or VIb metal, e.g. Ta, Mo, W but especially zirconium, which layer is conveniently from 0.01 to 0.05 mm thick. The carburised region 24 of the electrode metal 21, e.g. Ta, Mo or W, is shallower than it would be if there was no intermediate coating 22. <IMAGE>

Title: Scanned imaging systems
Inventor: LETTINGTON ALAN HAROLD
IPC: H04N3/08
Filed: 1982-03-09
Abstract: In a scanned imaging system operating in image space for high scan efficiency a lens system 3 focuses an image of a scene 1 in the vicinity of a primary facet of a rotating reflective polygon, and an optical system 11 directs radiation from the primary facet to focus on or adjacent a secondary facet and reflect thence to a detector 12. The radiation beam incident on the primary facet sweeps round therewith as the polygon rotates. The primary and secondary facets rotate together and may be (i) formed by the same facet 6, (ii) 27, 28 outwardly directed at an angle of 45Â° to the axis of rotation, the optical system being a lens 29,30 and roof reflector 31,32, and radiation being received parallel to the axis of rotation, or (iii) formed by a pair of inwardly directed reflecting surfaces forming a roof reflector 45,46, 49, 50 to displace radiation received perpendicular to the axis of rotation, parallel to that axis. A vertical scan is achieved by a flapping mirror, a further polygon, or by differing facet inclinations. For thermal imaging output from the radiation detector 42 modulates a light emitting diode 57 whose output is directed to an eye piece 58, or the detector is replaced by a light emitting diode for raster scanning.

Title: Method and apparatus for locking a phase locked loop onto a reference signal
IPC: H03L7/12
Filed: 1982-04-21
Abstract: A modulated carrier is fed to a balanced demodulator (18) which also receives a reference carrier from a voltage controlled oscillator (34) to produce an error signal representing phase and frequency error between the two carriers. The error signal is sampled in a sampler (22) and the sample integrated in an integrator (30). To prevent the loop locking onto a side-band of the modulated carrier an offset signal is fed by a frequency search system (36) to the integrator (30). The modulated carrier may be a television signal which is sampled by field and line banking pulses, the integrator having a short and long time constants associated with the field and line samples respectively. The offset (40, 42, 38, C150) is removed once locking is achieved. <IMAGE>

Patent GB-2108798-A (GB)
Title: Power source circuit
Inventor: RUSK GEORGE R
IPC: H02M3/315
Filed: 1982-10-22
Abstract: A power source for an electronic system re-uses a cyclically recurring event in the system as an on/off control for establishing a well- regulated series of rectified DC pulses which recur at a predictable and high frequency. The cycle of an SCR (20) is the regulating determinant of the system. In the preferred embodiment, the recurring event is a scan and retrace cycle of a CRT display. An SCR is switched off by the flyback transformer of the CRT horizontal deflection circuit. Therefore, since this turn-off time is determined by the flyback, the resulting conduction period is the net controlling regulation characteristic of the system. <IMAGE>
Patent GB-829302-A (GB)
Abstract: 829,302. Electric indicating systems. DE MONGE, G. March 26, 1956 [March 31, 1955], No. 9401/56. Class 40 (1). [Also in Group XXXVI] To determine the drift of an aircraft, i.e. movement normal to its longitudinal axis, the aircraft carries at its tail end two symmetrically located rectangular coils 15, 16 (Fig. 3) in perpendicular vertical planes, the lower horizontal arm 2 (Figs. 1, 2) of each coil being magnetically shielded by soft iron plates 4, 5, 9, 10 whereby movement of the aircraft along its axis causes equal voltages to be induced in the two upper horizontal arms 1 of the coils by cutting the vertical component 7 of the earth's field, but drift produces unequal induced voltages which are amplified and fed to a crossed coil indicator 19, 20 with a magnet pointer 21 whose displacement will indicate the resultant direction of movement of the aircraft. The amplifiers 17, 18 and indicator may be checked by feeding the same voltage from a battery 23 to both amplifiers simultaneously, or a single amplifier may be used and switched continuously from coils 15, 19 to coils 16, 20. The pointer 31 (Fig. 8) may be mounted coaxially with a compass needle 32 moving over a compass card 29. The combined output from the detector coils 15, 16 is also fed to two valves 90, 100 in push-pull whose combined anode current is therefore indicative of the speed of the aircraft, and is used to drive an integrator meter 104 indicating distance travelled. To correct the meter 104 for variations in the intensity of the vertical component of the earth's field, a flux meter (see Group XXXVI) produces a D.C. voltage proportional to this field component which is used to bias the valves 90, 100 automatically.
