Title: Improvements in or relating to the synthesis of oxygenated organic compounds
IPC: B01J27/051
Filed: 1949-08-03
Abstract: Alcohols are made by reacting olefines with CO and H2 in an oxygenation stage at elevated temperatures and pressures in the presence of an oxygenation catalyst with liquid phase hydrogenation of the product in the presence of a catalyst consisting essentially of a major proportion of charcoal supporting a minor proportion of molybdenum sulphide.  The process is of particular use when the oxygenated products contain sulphur.  The preferred catalyst contains 5-15 per cent of weight of molybdenum calculated as M0O3.  For details of catalyst preparation see Group III Abridgment. Conventional conditions are used for both stages although preferred for hydrogenation are temperatures of 425-500 DEG  F., pressures of 2,500-3,000 p.s.i., oxygenated product feed rates of 0.2-1.0 v/v/hrs. and hydrogen feed rates of 5,000-15,000 cu. ft. per barrel of feed. C8 oxygenated compounds are preferred for hydrogenation.  An illustration is given of the hydrogenation of oxygenated products obtained from C6-C8 olefines using the above conditions, and examples are provided of the hydrogenation of oxygenated compounds derived from C7 olefines in which greater activity, strength and alcohol selectivity is shown when the above catalyst is used as compared with known hydrogenation catalysts.  Specification 629,915 is referred to.ALSO:A catalyst used in the hydrogenation stage of the oxo synthesis consists essentially of a major proportion of charcoal supporting a minor proportion of molybdenum sulphide, e.g. 5-15 per cent by weight of molybdenum calculated as MoO3.  It may be made by impregnating charcoal pellets with ammonium molybdenate, drying as by heating at about 200-400 DEG F. and sulphiding with hydrogen sulphide at 800-900 DEG F. or by impregnating charcoal pellets with molybdenum oxide in ammonium sulphide drying and heating.  An example is given of a preparation by the first of the above methods.

Feb. 2, 1934, No. 20825. Divided out of and addition to 422,990. [Class 109] [See also Group IX] The process of the parent Specification by which threads, strings, bands, films, and the like are formed from a suspension of elastin-containing and /or collagenous animal fibres by pressing through a nozzle and then spinning, is modified by incorporating vegetable, animal or artificial fibres with the products, before or after the extrusion. Flax, ramie, wool, artificial silk, and like fibres may be used. The additional fibres may be mixed in the apparatus in which the suspension is made. If the fibres are long, they are cut up into lengths of 2-5 cms. If the textile fibres are incorporated after extrusion of the suspension, they are preferably arranged in fleece form between successive layers of the extruded suspension, thus giving bands or films which may be twisted or spun; when this method is adopted, the textile fibres are preferably first thoroughly moistened, and the combined mass is allowed to travel a certain distance before being introduced into the shrinking bath.

Title: Improvements in and relating to record controlled printing devices
Filed: 1961-06-09
Abstract: 910,580. Record controlled printing-machines. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 9, 1961 [June 22, 1960], No. 20837/61. Class 106 (1). In a record card controlled printing- machine of the kind having a type wheel 1, Fig. 1, moved in synchronism with the record card which is arrested at the correct time by a pawl 3 to print the sensed digit, the pawl 3 being normally held by a latch 4 connected by link 2 to the control magnet, there is a looking lever 6, normally held raised by a bail 5 but allowed to fall just before zero time to suppress printing of unwanted zeros by preventing anticlockwise rotation of latch 4. This prevents the type wheel being arrested at zero position, allowing it instead to complete its rotation to bring a blank portion to the printing station. If a digit is sensed latch 4 rotates and a lever 7 is turned to position a shoulder 8 under the looking lever as shown in Fig. 2 so that the latch can move to allow the pawl 3 to arrest the type wheel in the corresponding position. The levers 6 have lugs 9, Fig. 4, engaging the lever to the left. Where a significant digit is sensed the latch 4 is displaced before the bail 5 drops and the locking lever is held up by lever 7. The lugs 9 cause all levers to the right to be held up and rendered inoperative so that zeros are printed to the right of a significant digit. All zeros to the left of the highest significant digit are suppressed by operation of looking levers 6 as described.
