Title: Multiple trace crt display
IPC: G09G1/16
Filed: 1971-06-21
Abstract: 1320992 Cathode-ray tube displays WESTINGHOUSE CANADA Ltd 21 June 1971 [23 July 1970] 28929/71 Heading H4T Analog values such as cardiograms and encephalograms are displayed on a cathode-ray tube by an arrangement in which voltage waveforms representative of such analog values are periodically sampled, the samples stored and then utilized to intensity modulate a line scanned raster and to prevent the displayed curves exhibiting a discontinuous character in cases where a rapid change occurs between sampling points the intensity modulation of the beam is maintained between adjacent sample points. The modulation preferably consists in darkening the trace although bright-up modulation may be employed and in response to faulty operation or deviation of the values beyond certain limits the information contained in the system preceeding such condition is permanently recorded by a pen recorder. In the described embodiment four analog values, which are displayed as shown in Fig. 1 are supplied via inputs 10-13 (Fig. 2) to a sampler and coder 14 which loads a delay line 17 in such manner that the display of Fig. 1 is produced when the sequentail output code words are employed to control the brightness modulation of the beam of the display tube 24 which is scanned with a vertical line television raster. When line 17 is full the bits are recirculated under the control of switches 16 which with switch 15 cause the oldest piece of information to be rejected from the memory and replaced by a new piece of information so that the latter is continuously up-dated. As the bits are circulated they are also supplied to a 48 bit register 18 which holds the bit information for two line scans (2X four six bit words) so that the bits which emerge at terminal 49 appertain to the same position on a particular line, say the first line of the raster, as the bits just entering register 18 do in respect of the next line of the raster to be scanned (the third line of the full interlaced raster). The input and output bits are fed to respective shift registers 19, 20 from which successive six bit words (representative of the analog value of a sample) are transferred to respective registers 21, 22 which control the video generator to produce beam modulation output pulses the durations of which are dependent on the difference between the analog values of successive sample. The delay line 17 may contain several cycles of information and as the bits are circulated they are also fed to a register 27 which in response to the fault conditions referred to above causes the information to be recorded by pen recorder 29. Details of the sampler coder 14, the switches 15 and 16 and the video generator 23, are described with references to Figs. 3, 4 and 5 (none shown).

Specified monovinyl aryl compounds are styrene alpha- and ar-methylstyrene, ar-dimethyl- and ar-chloro-styrene, ar-ethylvinylbenzene, vinyl naphthalene, ar-methylvinylnaphthalene, ar-sec.-butyl and ar-trimethyl-styrene and specified polyvinyl compounds are di- and trivinylbenzenes, divinylnaphthalene, ar-divinyl, toluene and -xylene, ar-divinylchlorobenzene, ar-divinylethyl benzene and divinylether, while specified polyolefinic compounds are butadiene, isoprene, dimethallyl, diallyl, and cyclopentadiene. It is preferred that the monovinyl aryl compound constitutes more than 10 per cent, and the polyvinyl aryl or polyolefinic compound less than 50 per cent of the solution while the polymepic product may be prepared by polymerizing 0.1 to 60 per cent of the monovinyl aryl compound.  A plasticizer, e.g. dimethyl phthalate, may be added at any time during the preparation of the matrix, which may also incorporate non-polymerizable reinforcing material, e.g. glass fibres.  The polymerization may take place in the presence of a catalyst, e.g. benzoyl, lauroyl or hydrogen peroxide, potassium or ammonium persulphate and sodium perborate, and in bulk or solution.  The sulphonating agent may be sulphuric acid, oleum, chlorosulphonic acid, anhydrous sulphuric acid or sulphur trioxide and the sulphonation may be preceded by a swelling operation using as a swelling agent benzene, toluene, xylene, isopropylbenzene, chlorbenzene, tetrachloroethane or trichloroethylene.

Title: Improvements in space discharge tube amplifying systems

Filed: 1925-11-21
Abstract: 244,442. Standard Telephones & Cables, Ltd., (Assignees of Betts, P. H.). Dec. 13, 1924, [Convention date]. Thermionic amplifiers and detectors. - A coupling between two high-frequency valve amplifiers comprises separate inductance elements combined with capacity elements to form a single resonant loop-circuit, thus eliminating resonance effects due to the individual components. The separate input and output circuits are adjustably matched with the internal valve impedances, and shunt paths are provided for neutralizing the effect of inter-electrode capacity coupling. As shown in Fig. 1, the coupling-circuit 18 between the valves 16, 17 comprises inductances 13, 21 which may be coupled together, a blacking-condenser 14 between the plate and grid batteries 22, 24, and a variable condenser 19 which tunes the circuit as a whole to the mean carrier-frequency. The output circuit of valve 16 includes a portion of the inductance 13 adjusted to match the impedance of that tube. Similarly the input to the valve 17 includes a portion of the inductance 21 matched with the input impedance of that tube, whilst at the same time a step-up voltage effect is secured between the output and input inductances. A portion of the inductance 13 equal to the input portion of the inductance 21 is connected in series with a condenser 23 in a shunt circuit between the plate and grid of the valve 17 for the purpose of balancing the interelectrode capacity of that valve. Similarly a balancing- condenser 11 regulates the feed-back between the plate and grid circuits of tubes 16 through the windings of the frame aerial 10. The tube 17 and detector 26 are coupled by a loop circuit 27 similar to the circuit 18. Fig. 3 shows a modified arrangement in which a balancing-condenser 36 neutralizes the internal capacity of the tube 16, and a switch 42 is arranged to insert a variable condenser 48 across the plates of the tubes 37, 16, thus introducing a feed-back between the output and input circuits of tube 37, in opposition to and in excess of the regenerative action across its internal electrodes. As the capacity 48 is brought into circuit, the bypassing- condenser 43 is cut out, the primary winding of the transformer 41 then serving as a choke to increase the feed-back action.

Abstract: 987,476. Circuits employing cryotrons. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 1, 1962 [Aug. 21, 1961], No. 29558/62. Heading H3B. A transformer particularly applicable to superconducting circuits comprises two conducting sheets 62, 72 each having an aperture in register with which are mounted primary and secondary conductors 38 and 42. The effect of each sheet 62, 12 is to reduce the inductance of the conductors 38 and 42 so that coupling between them exists only adjacent an aperture, thus providing transformer coupling at this point. The transformer is particularly applicable to superconducting circuits as in this case D.C. coupling is achieved but it may also be used in normal thin film microstrip circuits. The primary conductor 38 which is mounted on the conducting sheet 62 is separated therefrom by an insulating layer which may be "Teflon" (Registered Trade Mark) or lacquer. If a step-up or step-down transformer is required several transformers can be connected with one set of windings in series and the other set in parallel. The transformers may be used to perform logical functions of their inputs. Various physical arrangements are described (Figs. 3, 5, 6, not shown).
