Title: Improvements relating to pick-up devices for colour television
Inventor: TROTT FRANK RUNCORN
IPC: H04N9/07
Filed: 1957-03-15
Abstract: 884,362. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 10, 1958 [March 15, 1957], No. 8549/57. Class 40(3). A colour television-signal generating system employs a pick-up tube 2 the target electrode of which, on the image side, is provided with two mutually insulated comblike electrodes 22, 23 (Fig. 2) which, in addition to serving as signal electrodes also function as, or are arranged to support optical filter elements which transmit green plus red and green plus blue light respectively. The scene to be transmitted is imaged on this target in a further filter 5 rotated at frame frequency and comprising segments 24, 25 (Fig. 3) which transmit green plus red and green plus blue light respectively. The output signals developed at the signal electrodes 22, 23 then consist of green representative signals during all field scans together with red representative signals during alternate fields of electrode 22 and blue representative signals during intervening fields at electrode 23. These signals are then supplied, via amplifiers 8 and 9, directly to one input of difference amplifiers 11 and 12 respectively and, via a switch 10 operating at field frequency to the other respective inputs of these amplifiers. In this manner, with the correct phase relationship between the rotation of filter 5 and the operation of switch 10, green representative signals are continuously supplied to the output line 17 whilst red representative signals are supplied to output line 16 during alternate fields with zero signal during intervening fields and blue representative supplied to output line 18 during the latter intervening fields with zero signals during the (alternate) fields when red signals are supplied to 16. In order to filter out H.F. components due to the interleaved signal electrode elements 22, 23 the bandwidths of amplifiers 8 and 9 are suitably restricted. Instead of this, however, the widths of the interleaved elements may be made sufficiently narrow so that the scanning spot always covers two elements. Due to the continuous production of the green signals no flicker occurs in the latter and due to the usually low brightness of the blue signals such flicker as does occur in these signals is not unduly noticeable. In the case of red signals flicker may be noticeable in bright areas and to reduce this the red signals may be stored on the target of a storage tube during the fields when they are available and then "read-out" during the intervening fields. Filters 13 and 14 reduce the bandwidths of the red and blue signals respectively relative to the green signals and additionally remove some of the noise signals from the two signal plates of the tube. Delay device 15 is arranged to have the same delay as that produced by the filters 13, 14. Specifications 657,634 and 743,156 are referred to.

Title: Electrostatic recording of information
IPC: G03G15/32
Filed: 1958-03-19
Abstract: 888,438. Selective printing processes. KOLB, O. K. (Haloid Co.). March 19, 1958, No. 8760/58. Classes 100(2) and 100(4) [Also in Group XIX] An electrostatic computor output printer comprises a first charging station 19 which charges a dielectric web 25 up to a level just below break-down and a second station 20 which selectively applies a low amplitude pulse through electronic coincident circuit means to a series of aligned electrodes, e.g. 55 spaced from a counter-electrode 53. As shown in Fig. 4, alphabetical information is printed, the character elements are on a continuously rotating drum and by the use of digital computor techniques incorporating a marker 51, a counter 59, a matrix 60, and a character marker 62 controlling a character counter 65, and a comparison circuit 66, the appropriate gates 61 are operated at the correct moment for an image to be formed between electrodes 55 and the rotating drum forming the counter-electrode. In this arrangement the drum may be placed at a slight angle relative to the web, or the character rings may be displaced relative to one another to compensate for slanting effect due to the time required to step the matrix 60. In a form described with reference to Fig. 5, not shown, simultaneous printing in all columns is achieved by the use of a register which stores all the characters for a line and in a single revolution of the drum, characters are transferred to the paper in random fashion, i.e. irrespective of digit position, until all images in one line are made. The printer may also (see Group XIX) form a binary record by selectively energizing "1" or "0" electrodes or forming dots as the web is fed so that a curve, representing voltages &c. is made. Inking. After the electrostatic image is made at the second station 20, Fig. 2 the web 25 goes through a development mechanism 28, where the images are rendered visible by depositing a liquid ink on a finely divided material such as an electroscopic pigmented resin powder, which adhers to the charged parts of the web. The visible images are subsequently heated in an oven to dry the ink or fuse the resin in a fuser 30.

Title: Improvements in or relating to electrical hybrids
Inventor: SOSIN BOLESLAW MARIAN
IPC: H01P5/04
Filed: 1954-03-25
Abstract: 770,406. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 8, 1955 [March 25, 1954], No. 8779/54. Class 40 (8). [Also in Group XL (c)] A hybrid bridge network, which may be made adjustable so that it can be operated as a switch for high-frequency electrical energy, is constructed by associating together a number of coaxial line elements. The type of bridge on which the hybrid is based is one in which the arms are of the same impedance and are resistive, capacitive, resistive, and inductive, in sequence round the bridge. In deriving a hybrid network from this bridge the diagonals of the bridge are used for the input connections and the resistive arms for outputs. The input and output connections can, of course, be interchanged without altering the nature of the hybrid. As shown diagrammatically in Fig. 3, the resultant hybrid has input connections at 15 and 16, output connections at 7 and 10, and a capacitive impedance 8 in the arm opposite the inductive impedance comprising units 11 and 12. The construction of the hybrid from coaxial line elements is shown in Fig. 2. The input and output connections are indicated by the same references as in Fig. 3 and the capacitive reactance 8 is formed by the length l1 of coaxial line 8A, 8B. The inductive reactances 11 and 12 comprise the two coaxial lines of lengths l2 and l3 which have the same references and are shorted at 13 and 14. For equal power balance conditions the length l1 is found to be approximately #/8 and the lengths l2 and l3 slightly greater. If the hybrid is to be used as a switch the length l3 may be made #/4 so as to render the line 12 inactive and the coaxial structure so constructed that the termination 13 is a slidable shorting ring and the length of inner conductor 8A may be adjusted by sliding it into a housing in conductor 15A. In one limiting position of the adjustments where l1=l2=0 input 15 is connected to output 7 and input 16 to output 10. If the lengths l1 and l2 are then gradually increased a gradual change-over is effected until when these lengths are #/4 input 15 is connected to output 10 and input 16 to output 7. In any position of the adjustment the two inputs are isolated because of the balance conditions in the hybrid. The adjustment of the lengths l1 and l2 may be effected simultaneously by a mechanical ganging arrangement. If two radio transmitters are coupled one to each of the input 15 and 16, a common aerial to output 10 and a balancing dummy load to output 7, the phase of the transmitters can be adjusted so that under balanced operating conditions substantially all the power is dissipated in the aerial and a negligible amount in the balancing load. The switch may be operated as necessary to connect either one of the transmitters to the aerial and the other to the dummy load so that repairs and tests may be carried out on either transmitter without interrupting the transmission.
