Title: Apparatus for processing television signals
Inventor: MONTEATH GEORGE DEWAR
IPC: H04N5/208
Filed: 1965-05-03
Abstract: 1,110,319. Television. BRITISH BROADCASTING CORPORATION. 13 April, 1966 [3 May, 1965], No. 18576/65. Heading H4F. An apparatus for processing an input television signal for the purpose of providing vertical aperture correction comprises a delay device for delaying the input signal by one or more line periods, and a correction circuit the effect of which is to subtract from the signal entering the delay device a proportion of the signal leaving the delay device, and to subtract from the signal leaving the delay device a proportion of the input signal. The overall operation of the apparatus is to provide an output signal in which the signal due to any one line has subtracted from it (where a one-line delay is used) a proportion of the signals due to the immediately preceding and following lines. An embodiment is illustrated in Fig. 3 where one line delay 23 is preceded and followed by adders 22 and 24 for introducing the correction signals. The signals for three successive lines are denoted by e n-2 , e n-1  and e n , the line for which correction is applied at the instant considered in the Figure being e n-1 . The subtraction of the line output signal from the input signal is effected by way of the path including inverter 26, adder 30, attenuator 27 and adder 22. The subtraction of the input signal from the line output signal is effected by way of the path including adder 30, attenuator 27, inverter 28 and adder 24. In addition to causing the main line e n-1  to be reduced by the proportions ke n  and ke n-2  of the adjacent lines, a proportion 2ke n-1  of the main line is added back to the main line. This has the effect of maintaining the signal amplitude constant (and hence also the brightness) as the correction factor K is adjusted. Another embodiment, Fig. 2 (not shown), does not introduce the signal 2ke n-1  into the output and hence F does not stabilize the brightness. According to modifications the inputs for adder 30 are taken from positions in the main path after adders 22, and 24. Furthermore, the circuit may be arranged so that the difference signal from adder 30 is of the form e n-1 -e n . This signal is then applied to adder 24 directly and inverted for application to adder 22. A modification of Fig. 3 is described with reference to Fig. 4 (not shown) in which a low-pass or band-stop filter is inserted at point X to aviod modifying a chrominance signal when applying correction to a colour signal. Alternatively a non-linear network may be inserted arranged to suppress weak signals so as to avoid accentuating noise by the correction. To allow for a delay T introduced by the inserted device, the main delay device 23 is reduced in value by T and auxiliary delays of T are inserted in the main signal path before adders 22 and 24.

Abstract: 313,926. Kolster - Brandes, Ltd., (Assignees of Kolster, F. A.). June 19, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Bearings and distance, determining.- A method of navigation for aeroplanes, ships, &c. utilises a plurality of intersecting beams of characteristically different radiant energy. By directing from the ground two beams 4, 5, Fig. 1, of radiation from sources 11, 12, having axes 1, 2 intersecting at 3 (the two beams being of different wavelength or modulated either by coding or a characteristic tone - frequency) an aeroplane, by noting which beam it passes first, or whether the two are superposed, is aware of its approximate altitude. In another arrangement, Fig. 3, three beams 4, 5, 6, of radiation are employed from sources 11, 12, 10 and having axes 1, 2, 3, the two former being inclined to the horizontal and the latter being vertical and passing through the intersection of the first two. All three fields are characterized differently. This arrangement gives an indication of direction and altitude, and radiation from beam 6 may guide the aeroplane to a landing field 27. The beams are produced by a transmitting aerial 14, Fig. 5, coupled at its centre to an oscillator and modulator 18, 19, and situated at the focus of a paraboloidal reflector 13, of wire mesh or sheet metal. The reflector is mounted on an horizontal bearing 24, on a pillar mounted on a turntable 26. The wavelength of the radiation is preferably four times the focal length of the reflector. The code signals from two transmitters may be synchronized to produce a third characteristic code when the two beams overlap.

[Also in Group XL (c)] Voltages of equal frequency are applied in push-pull and co-phasally respectively to corresponding pairs of grids of a pair of multigrid valves so that a differential D.C. voltage E representing the relative phase of the voltages B-B and A-A is derived across anode resistors 46, 47, shunted by smoothing capacitors 48, 49. This voltage E after chopping at mains frequency by a synchronous converter 33 and amplifying at 34 may then be applied to a two-phase motor 36 to which a reference mains phase is also applied so that the motor 31 is driven in correct sense to adjust a phase shifter 21 in the input of one voltage, e.g. B-B to the phase discriminator to restore the inputs to the valves to normal phase quadrature relation and to drive an indicator 29 representing in magnitude and sign the relative phase of the voltages. As shown, the voltage A-A may be derived from a direction finding antenna rotated in azimuth by a motor 12 at mains frequency so that the output after amplifying detection and limiting is a constant amplitude low frequency of phase representing the direction of a received signal. Further, a two-phase generator 14 also rotated by the motor 12 may apply equal outputs to the stationary field coils of a continuous phase shifter (resolver) so that the voltage derived from an adjustable rotor 22 is constant but variable in phase and forms the reference phase for the discriminator.

Abstract: 1286722 Sterilising apparatus M FROLICH 21 April 1970 [28 April 1969] 19098/70 Heading A2D A method of sterilising apparatus used for the heat treatment of liquid products comprising at least one closed vessel, heat exchanger and connecting pipes with valves, comprises displacing air from the apparatus by steam conducted into the vessel, a major part of the pipes being filled with hot water, and circulating the water whilst supplying steam, the water being sprayed into the vessel arid thereby heated by the steam fed into the vessel so as to reach the sterilisation temperature. The supply of steam is regulated to permit sterilisation of the apparatus, the supply after a sterilising time being terminated, the recirculating water being cooled by use of the heat exchanger, and pressurised sterile air being then supplied to the apparatus to maintain an excess pressure until the temperature of operation of the heat treatment apparatus is reached. The water is then discharged from the apparatus. A suitable apparatus is shown in the figure. This apparatus is sterilised by opening the valve 18 and passing steam into the closed vessels 1 and 2 thus displacing air which is discharged through outlet pipe 16. During this step only the valves 21 and 5a are closed and three-way valve 25 is positioned to connect pipe 13 to heat exchanger 7. After displacement of air, valve 28 is closed, valve 27 is opened and the connecting pipes filled with hot water which water is further circulated by pump 14. During this step, hot water is sprayed from nozzles 11 and 12 into the closed vessels. The temperature of the circulating water is registered at 29. Sterile air may be admitted to the closed vessels when the sterilisation is complete, by opening valve 21.
