[Class 2 (ii)] [Also in Group XV] Nitrocellulose or cellulose acetate sheets, films, tubes, or other shapes are rendered plastic so that they may be used for covering or coating wood, metal, or other articles, or so that they may be moulded, by treating them with a liquid containing a mixture of a non-solvent with a halogenated hydrocarbon or halogenated ether converted to a solvent by addition of an agent such as alcohol, and also containing ethylene glycol phthalate. The coating of air screws is excluded. A mixture with alcohol of ethylene dichloride, methylene dichloride, dichlor - ethyl ether, or di - or tri-chloroethylene, may be used as solvent together with toluene, xylene, or petrol as non-solvent, and ethylene glycol phthalate as plasticizer. The plasticity imparted may be controlled by varying the proportion of alcohol, e.g. methylated spirit, in the treatment bath. A sheet of nitrocellulose is treated with the softening solution and then stretched on to a wood or other surface. The wood may be coated first with an adhesive consisting of dissolved nitrocellulose scrap, gum elemi, and acetone. A second layer of adhesive similar to the first but with the gum omitted may be applied, before application of the sheet material.

Title: Data storage apparatus
IPC: G05D13/62
Filed: 1973-01-31
Abstract: 1396834 Automatic control of movement INTERNATIONAL BUSINESS MACHINES CORP 31 Jan 1973 4865/73 Heading G3N A data transducer of a rotatable data store is controlled, when moving more than one data track away from a first data track, to accelerate over a first distance, then move at constant velocity over a second distance and decelerate and be located in a transducing position over the remaining distance. As shown a servo transducer 7, Fig. 6, detecting a pattern on a storage disc provides signals which are pre-amplified by an amplifier 23 and fed to a circuit 24 in which they are demodulated to produce a position-error dependent voltage. This voltage is fed through a compensator circuit 25, stabilizing the servo response, to a drive circuit 26 which energizes the appropriate half of a voice-coil winding 20 to move an arm 18 in a direction to reduce the position error of the transducer 7. Transfer between tracks on the storage disc is effected in accordance with a predetermined velocity profile, comprising an initial accelerating position, a steady velocity position and a deceleration to a velocity at which capture can be effected by the closed position servo loop. During the acceleration phase an accelerate signal is applied on line 70, Fig. 21, which is fed through OR gate 71 to the drive circuit 72 to energize coil-half 73, 74 for access direction as determined by gate 75, controlled by a direction signal on a line 76. During acceleration a store 78 is updated by the output of a comparator 81 so that the store-contents tracks the instantaneous velocity signal on a line 82. During the constant velocity phase the arm moves at the final velocity held in the store 78 when pulses are fed from access logic not shown, the output of the comparator controlling through AND gates 85, 86 the drive circuit 72. During retardation, the output of store 78 falls to zero and a capture velocity signal from a store 90 applied to the comparator 81 and the drive circuit 72 controlled accordingly.

Title: Catalytic composition for conversion of hydrocarbon distillates
IPC: B01J27/049
Filed: 1960-02-12
Abstract: The activity of a composite catalyst comprising an active siliceous cracking component together with a hydrogenating component consisting of nickel oxide and/or cobalt oxide, said catalyst having a nickel content (calculated as Ni) of from 0,5 to 25% by weight when nickel oxide is present and a cobalt content (calculated as Co) of from 3 to 25% by weight when cobalt oxide is present, is increased by heating the composite catalyst in contact with a stream of substantially dry, non-reducing gas at a temperature of from 1200 DEG -1600 DEG F. for a period of time sufficient to induce a substantial increase in catalytic activity as measured by the ability of the catalyst to convert hydrocarbon feed fractions to product fractions boiling below the initial boiling point of the feed.  In an example (No. 1), the catalyst is prepared by impregnating 15 litres of silica-alumina beads containing 90% by weight of silica with 12 litres of an aqueous solution of nickel acetate, after draining and heating to 250 DEG F. for 10 hours the beads are calcined at a temperature which finally reached 1000 DEG F., a stream of dry air being passed over, and the beads are then roasted at 1400 DEG C.  The catalyst is then reduced and sulphided using a hydrogen stream containing hydrocarbons and carbon disulphide using a pressure of 1200 psig. at 560 DEG F.  The catalyst may be used for hydrofining oils such as a naphtha fraction having a boiling point range of 220 DEG -440 DEG F. which is treated with 3500 SCF of hydrogen per barrel and passed over the catalyst at 700 DEG -750 DEG F. to produce a stock of boiling range 370 DEG -455 DEG F. which is further treated with 6500 SCF of hydrogen per barrel, preheated to 596 DEG F. and passed over the catalyst at 680 DEG -750 DEG F.  In Example 2, the catalyst was prepared by the decomposition of nickel nitrate.  The carrier may comprise silica-alumina, silica-magnesia, silica-zirconia, alumina, bentonite or kaolin and may also contain halides.

Title: Production of silica hydro-organosols and aerogels
IPC: C01B33/145
Filed: 1958-02-18
Abstract: A process for preparing an acidic, silica hydro-organosol of extremely low salt-content comprises contacting an acidic hydro-organosol containing silica, water, a water-miscible organic liquid, mineral acid in an amount to give a pH between 1.8 and 4.5 and at least 0.1% by weight of a salt of such mineral acid with the hydrogen-form of a water-insoluble, strong, cation-exchange material and with the sulphate-form of a water-insoluble, anion-exchange material containing salt-forming nitrogen atoms, either simultaneously or successively, and at a temperature below 30 DEG C. until the hydro-organosol contains less than 0.01% by weight of said salt, contact with the anion-exchange material ceasing before pH exceeds 4.5.  If the hydro-organosol is first contacted with the strong cation-exchange material and then with the sulphate form of the anion-exchange material, the initial sol has a pH of 3-4.5 and is maintained in contact with the cation-exchange material until the pH is between 1.8 and 2.5 and then is contacted with an anion-exchange material until the pH is between 3 and 4.  If the sol is first treated with an anion-exchange material the hydro-organosol has a pH between 1.8 and 3.5 and the pH is not allowed to exceed 4.5.  The sol is then contacted with a cation-exchange material until the pH is between 1.8 and 3.3 The resulting sol may be further treated with an anion-exchange material until the pH is between 3.5 and 4.5 and may be further treated with each kind of ion-exchange resin.  If the hydro-organosol is simultaneously contacted with a mixture of the anion-exchange and cation-exchange material the initial sol generally has a pH of 2.5-4.5 and is maintained in contact with the mixture of resins at a pH between 2.5 and 4.  A silica aerogel can be obtained by a process of U.S.A. Specification 2,093,454.  Specifications 649,896, 654,850, and U.S.A.

Title: Process for the production of press-moulding materials, by condensation of phenols with formaldehyde or substances that yield formaldehyde
IPC: C08G8/08
Filed: 1933-02-21
Abstract: Press-moulding materials are manufactured by condensing phenols with formaldehyde or substances yielding it, in the proportion of more than 1\ba1/2\be molecular proportions of methylene groups to one of phenol, to produce a fusible resin, hardening this at about 50--70 DEG  C. until a Vikat needle with a cross-sectional area of about 2 sq. mms., loaded with a weight of about 5 kgs., penetrates through 1 cm. in 5--20 minutes, or until a sample of the resin freed from volatile constituents shows a rising power, as determined by Krahl's method, of 100-200 mms. at a pressure of 300 kgs. per sq. cm. (the solidified resin at this stage giving a powder that does not sinter at 70--100 DEG  C.), powdering the resin and freeing it from volatile substances, preferably by heating at 80--100 DEG  C. in vacuo.  The initial fusible resin may be prepared by combining phenol with the necessary quantity of formaldehyde, or by first preparing a resole from equimolecular proportions of phenol and formaldehyde and treating this with more formaldehyde, or by combining a novolak with hexamethylenetetramine or formaldehyde or both.  The hardening may be carried out by heating the resin in flat moulds, the thickness of which should not exceed 10 cms., in a liquid bath, preferably a water bath.  In examples: (1) a resole prepared from phenol and formaldehyde in the presence of hexamethylenetetramine is treated with a solution of hexamethylenetetramine, the water is distilled off and the resin is heated in moulds 6--10 cms. thick in a water bath at 60 DEG  C. until the hardness or rising power reaches the value specified, whereupon it is cooled, powdered and heated in vacuo to 70--100 DEG  C.; the product yields transparent yellow moulded articles; (2) a novolak is treated with hexamethylenetetramine and the product is worked up as in (1); (3) phenol is condensed with formaldehyde and hexamethylenetetramine, the water is distilled off and the product is kept at 60 DEG  C. for 2--3 hours and then worked up as in (1).  In any of the examples the phenol may be replaced by cresols or other phenols.  There may be added to the resin, at any stage of the manufacture, 1--5 per cent of stearic acid or other flowing agents to increase the rising power, or up to 10 per cent of salicylic acid or other aromatic carboxylic acids to prevent turbidity.  Organic or inorganic dyestuffs may also be added.  The p products may be employed for the production of pressed articles for electrotechnical, household, ornamental and fancy purposes.
