Title: Improvements in or relating to the manufacture of oxygenated organic compounds
IPC: B01J23/78
Filed: 1929-07-24
Abstract: 337,014. Dreyfus, H. July 24, 1929. Oxygenated organic compounds such as ethanol. acetic acid, acetaldehyde, methylacetate and higher homologues are produced from oxides of carbon and hydrogen in the presence of catalysts consisting of or comprising ferrites, ferrates, cobalites or cobaltates, especially of alkali and alkaline earth metals, and of aluminium, preferably at 200‹-600‹ C., and especially at 250‹- 350' C., and under 50-500 or more atmospheres. The reaction gases may be coke oven, producer or water gas, and may wholly or in part be replaced by oxygenated organic compounds synthesized therefrom, such as methanol or ethanol. In this modification, the methanol or other compound may be prepared in a preliminary operation by passing gases containing carbon monoxide or dioxide, or both, and hydrogen over zinc oxide or basic chromate, or other suitable catalyst. Alternatively, compounds capable of yielding methyl alcohol, such as methyl formate or acetate, or dimethyl ether may be used. Methane may wholly or in part replace the hydrogen, and nitrogen may also be present. The catalysts may be employed in admixture or association with zinc, magnesium, calcium, aluminium, chromium, molybdenum, vanadium, tungsten or uranium, or a mixture thereof, either as metals, oxides or other compounds. Copper may be present. Apparatus made of copper, of steel lined therewith, or of steel containing molybdenum, tungsten, cobalt or nickel may be employed.

Title: Improvements relating to the treatment of water
IPC: B01J39/04
Filed: 1949-09-02
Abstract: Hard water containing alkalinity is softened and its alkalinity reduced to a low value by passing it through a bed of organic cation-exchange material consisting of a mixture of a material in which the exchangeable cations are associated with sulphonic acid groups and a material in which the exchangeable cations are associated with carboxylic groups, the bed having been activated by treatment with both acid and salt.  The two materials are preferably present in quantities such that their total exchange capacities correspond respectively to the permanent and the temporary hardness of the water under treatment.  The carboxylic groups may be acetic acid groups.  In regenerating the bed periodically the amounts of salt and acid used may be as calculated to regenerate the sulphonic acid and carboxylic groups respectively.  Specifications 450,574, 498,251, [Group IV], 577,707, 588,380, [Group IV], 598,130, and U.S.A. Specification 2,340,111 are referred to.

Title: Improvements in tuning indicators for frequency shift telegraph systems
Inventor: TERLECKI RENAT
IPC: H04L27/16
Filed: 1950-09-21
Abstract: 732,102. Testing-apparatus for telegraph receivers. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Aug. 2, 1951 [Sept. 21, 1950], No. 23220/50. Class 40 (3). [Also in Group XL (c)] A tuning indicator for use in a frequencyshift telegraph system comprises a cathoderay tube having two pairs of deflecting plates, means for applying voltage from an input terminal to one pair of deflecting plates and further means for applying the voltage through oppositely-directed rectifiers to the plates of the other pair respectively. As shown, the received signals, after amplification and discrimination at 12, 13 respectively, are applied as positive or negative voltages to the telegraph apparatus 15 and via amplifier 16 to the plate 18 of the pair of plates 17, 18 of the tube 19. Positive-going voltages are also passed via rectifier 20 to the plate 22 and negativegoing voltages by rectifier 21 to the plate 23. The succession of positive and negative voltages from the output of the amplifier 16 produce a V-shaped trace on the screen of the cathoderay tube, the arms of the V being of equal length when the signals, i.e. marks and spaces, are correctly received. A saw-tooth generator 24 of a frequency high relative to that of the signal impulses, connected to the plate 17 expands the linear trace of the arms of the V into a series of spaced parallel lines, as indicated by Figs. 2, 3 (not shown). The tube may be used for normal oscillograph presentation of signals applied to terminals 29, 30 connected by switches 28<SP>11</SP>, 28<SP>111</SP> to the plates 22, 23 and the plate 18 may be earthed by a switch 281 preferably ganged with the switches 28<SP>11</SP>, 28<SP>111</SP>.

Title: Purification of alcohols
IPC: C07C29/74
Filed: 1947-08-25
Abstract: Aliphatic alcohols are purified and in particular the odour of aliphatic alcohols prepared by the treatment of the corresponding olefine with sulphuric acid is improved by contacting the alcohol in the liquid phase with cuprous oxide in preferred amounts of 0.5 to 1.5 per cent by weight of alcohol treated.  The alcohol may be substantially anhydrous or contain water and is preferably neutral. The mixture may be stirred or refluxed or the alcohol may be passed through a bed of the oxide.  In examples: (1) aqueous ethyl alcohol is stirred with 0.5 per cent cuprous oxide and (2) isopropyl alcohol is refluxed with 1.5 per cent cuprous oxide.

Title: Liquid film gate for an optical printer
IPC: G03D15/00
Filed: 1970-05-14
Abstract: 1312503 Liquid film gate EASTMAN KODAK CO 14 May 1970 [3 July 1969] 23422/70 Heading G2A A liquid film gate 11 for use in a photographic projection printer Fig. 8, (not shown) comprises a pair of opposed complementary gate halves 10 each having an optical window 12, there being rows of jet orifices 14 parallel to the transverse edges of each window 12 and rows of vacuum orifices 24 extending across the entrance 22 to and exit 23 from, the film gate beneath transverse slots 20. When film F enters the gate at the end 22, passing the slots 20 results in the film being swept by air moving from outside into the slots 20. As the film advances, it is further swept and coated by liquid moving upwardly from the upper orifices 14 to the slots 20. At the windows 12 the film is halted while an image of a frame thereof is projected on to a positive film (P). After the exposure is made, the film is advanced where it is further swept by liquid from the lower orifices 14 which moves towards the slots 20 adjacent the exit 23. As the film passes these lower slots, the liquid is substantially removed from the film surface. Each gate half is provided with a pair of ridges 68, 68' and a pair of depressions 70, 70' which so co-operate when the halves all resiliently held together, as to permit the passage of a spliced film through the gate with losing the vacuum in the gate. The liquid has a refractive index approximately the same as that of the film F, and this results in scratches on the film F not being projected onto the positive (P). The flow of liquid to the orifices 14 is pulsed in synchronism with the movement of film through the gate. The liquid is recycled after first being filtered, debubbled, and heated.
