Title: Data transmission
IPC: G06T9/00
Filed: 1970-06-02
Abstract: 1318114 Run-length encoding data transmissions; facsimile system DACOM Inc 2 June 1970 [2 July 1969] 26449/70 Headings H4F and H4P Binary data generated by line-by-line scanning of a document is run-length encoded by one or more code-words of different bit lengths. The use of more than one code word for a run causes a longer bit code word to start the coding of the next run of the same binary state. When a run is encoded by a word whose capacity is used by less than a certain amount, a shorter bit code word is used to start the coding of the next run of the same binary state. If say a 3-bit word is two small to code a run, the excess is coded by a 4-bit word and if necessary a 5-bit word and so on. If more than one code word is used then the longest bit-length code word used is used to start the coding on the next following run of the same binary state. On the other hand if a run is so short that the single code used only uses less than 25% of the capacity then a 6 code word shorter by 1-bit is used to start the coding of the next following run of the same binary state. The decoder of the remote receiver receiving the transmitted codes recognizes the end of a run by detecting a code word which is less than full, is that even if the run length exactly equals the capacity of one or more code words a further code word, one bit longer, but all zero must be transmitted. The encoded data is in blocks of from 256 to 267 bits of encoded data, according to the differing lengths of code words used. Each block includes at the beginning a synchronizing code and a leader lable consisting of the positions on the facsimile of the first 1 and 0 binary runs of of the block and a tag bit indicating the binary state of the first run. To avoid the synchronizing code being generated during the normal course of run-length encoding, odd length code words are complimented and certain code values are restricted. The start and stop commands of the facsimile reproducer are transmitted as modified header labels. Columns of two or three elemental areas, that is elemental areas imediately above one another in two or three adjacent rows, are similarly run-length encoded. A prefix word indicates whether the run-length relates to a column of white, black or white and black elemental areas. For a mixed white and black column the decoder arranges the elemental areas in accordance with the element area imediately above the column in question.

Title: Process for the production of aliphatic carboxylic acids and esters of the same
Inventor: REPPE WALTER
IPC: C07C51/12
Filed: 1951-11-16
Abstract: Aliphatic carboxylic acids and their esters are produced by the reaction of saturated alcohols with carbon monoxide at elevated temperature and superatmospheric pressure in the presence of catalysts consisting of metal carbonyls and a halogen or a halogen compound while having present during the whole course of the reaction an appreciable amount of an organic liquid solvent inert under reaction conditions and having a critical temperature above the reaction temperature.  The preferred temperature range for the process is 250-320 DEG  C. and the preferred pressure range is 200-300 atmospheres.  Suitable inert solvents are the aliphatic carboxylic acids which are formed in the reaction, carboxylic acid esters, higher paraffinic hydrocarbons, cyclohexane homologues and benzene and its next higher homologues. Non-aromatic saturated ketones or higher boiling tertiary amines, such as pyridine or dimethylaniline may also be used.  The catalyst should be either a metal carbonyl or capable of forming a metal carbonyl under the reaction conditions.  Halogen either in the form of a halogen compound, e.g. a halogenated hydrocarbon or free halogen, is also essential.  Iodine is the preferred halogen.  Bismuth may be used as an additional activator.  In the examples methyl alcohol is reacted with carbon monoxide in the presence of (a) nickel acetate and iodine; (b) nickel metal and iodine; (c) nickel carbonyl and iodine, and (3) nickel carbonyl, iodine and bismuth in the presence of various solvents to give acetic acid and methyl acetate.

Abstract: 727,785. Automatic frequency control. STANDARD TELEPHONES & CABLES, Ltd. Oct. 2, 1953 [Dec. 11, 1952], No. 27066/53. Class 38 (4). [Also in Group XL (c)] In a transmitter employing two carrier waves differing in frequency by a specified amount, the first is generated by means including a first oscillation source and the second by means comprising a second oscillation source, a source of reference waves, means for adding the frequencies of the two oscillation sources and subtracting from their sum the frequency of the reference waves and means for stabilizing the frequency of the second oscillation source with reference to that of the reference waves. In one embodiment, for transmitting video and audio signals on two carriers of 840 Mc/s. and 844.5 Mc/s. respectively, the output from the video carrier master oscillator 4, Fig. 1, at 3.889 Mc/s. is frequency multiplied by nine in circuit 5 and twenty-four in circuit 6 to give the 840 Mc/s. carrier, which is amplitude-modulated in circuit 8 by the video source 7 and passed through the vestigial side-band filter 11 and diplexer 9 to the aerial 10. The audio input to the thermionic reactance 12 frequency-modulates a 3 Mc/s. oscillator 13 the output from which is fed, through a buffer stage 14 to a mixer 15 which is supplied also with the 35 Mc/s. video carrier occurring at the output of multiplier 5. The 38 Mc/s. resultant is fed to a mixer 18 which also receives a 2.8125 Mc/s. input from the stable reference oscillator 16, operating at 0.1875 Mc/s., after frequency multiplication by fifteen in circuit 17. The 35.1875 Mc/s. output from the mixer 18 is multiplied by twenty-four in stage 19 to give the F.M. audio carrier at 844.5 Mc/s. which passes through amplifier 20 and diplexer 9 to the common aerial 10. The frequency of oscillator 13 is automatically maintained at sixteen times that of the reference source 16 by a control signal applied to the thermionic reactance 12 from a phase comparator 22. The latter is fed with two 11.719 Kc/s. waves derived from 3 Mc/s. source 13 after frequency division by two hundred and fifty-six in circuit 21 and 0.1875 Mc/s. source 16 after frequency division by sixteen in circuit 23. In a modification, Fig. 4 (not shown), the reference oscillator 16 operates at 2.8125 Mc/s. multiplier 17 is omitted and divider 23 reduces its input frequency in the ratio 1/240. Circuits for the 3 Mc/s. oscillator 13, control reactance 12 and phase comparator 22 are described. The comparator comprises a known diode bridge 34, 35, Fig. 3, control voltages being developed across the load resistances 30, 32, which are included in the grid circuit of the reactance valve 25. This grid circuit also includes, in series, the terminals of the audio modulating source. An adjustable capacity 28 connects the grid of valve 25 to a tapping on the tuned circuit 26 of the oscillator. 13, so that the desired frequency swing may be obtained.

Filed: 1920-09-24
Abstract: 172,757. Taggart, J. Scott-, and Radio- Communication Co., Ltd. Sept. 24, 1920. Thermionic relays.-A thermionic relay is arranged so that an input impulse applied in the grid, plate, or filament circuit causes a variation of the plate current, which acts by mechanical means to vary the grid potential in a gradual manner so as to produce further variation in the plate current. As shown in the drawing, the imput impulse is applied between the terminals I, N in the grid circuit, which also includes a sliding contact S movable over a potentiometer resistance R. The impulse causes a variation in the plate current through a milliameter A, the pointer of which moves the sliding contact S and applies potential to the grid in the same sense as the original impulse, thus giving a building-up effect. The resistance R is preferably liquid, and may comprise a trough of copper-sulphate solution or mercury. The valve may be used as a low-frequency oscillation-generator or calling- device by arranging an oscillatory circuit in the plate circuit.
