Title: A process for separating fractions of different properties from mixtures of hydrocarbons by crystallisation
IPC: C10G21/02
Filed: 1939-02-20
Abstract: 525,388. Resolving mixtures of paraffin and non-paraffin hydrocarbons. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Feb. 20, 1939, No. 5622. Convention date, March 11, 1938. [Class 91] Hydrocarbon mixtures are separated into relatively paraffinic and non-paraffinic fractions by cooling in presence alternately of good and poor solvents for paraffins, the temperature being reduced in each subsequent extraction with the same type of solvent. Specified solvents for paraffins are saturated hydrocarbons such as ethane, propane, butane, pentane, cyclohexane, decahydronaphthalene, and gasolines and kerosenes poor in aromatics. Solvents for non-paraffins are polar or readily polarizable compounds such as toluene, chloroform, dichlorethane, carbon disulphide, ethers, esters, ketones, alcohol, sulphur dioxide, pyridine, and furfural. In an example, petrolatum diluted with 2 vol. of chloroform and 2 vol. of dichlorethane is filtered at 20‹C., and the cake washed with the solvent mixture ; the filtrate is freed from solvent, dissolved in pentane and cooled to and filtered at 0‹C.; subsequent treatments of the solvent-free filtrates are with chloroform and dichlorethane mixture at 0‹C., pentane at -20‹C., and chloroform-dichlorethane mixture at -20‹C. When a hydrocarbon such as propane is used to precipitate non-paraffinic hydrocarbon the filtrate still containing propane may be treated with the polar solvent in the next stage, cooling being. effected by evaporating part of the propane. The Specification as open to inspection under Sect. 91 also describes separation by lixiviation instead of by precipitation ; it also includes an example in which the first precipitation treatment is applied at -20‹C. and the subsequent treatments at -30, -40, -50, -60, and -70‹C. This subject-matter does not appear in the Specification as accepted.

Abstract: 505,265. Calculating-apparatus. MAXSON CORPORATION, W. L. Nov. 4, 1937, No. 6486/39. Convention date, Nov. 30, 1936. Divided out of 505,114. [Class 106 (i)] A computing-apparatus comprises, in combination a rotary input member operable in proportion to a basic variable, a rotary output member, and mechanism, including a flat disc. like rotary member 9 having teeth 41 disposed at uniform inter. vals along a spiral path, interconnecting said input and output members for causing the total rotation of the output member throughout a plurality of rotations to be constantly proportional to a predetermined, non-linear function of the basic variable. The rotary output member is a crown gear 49 engaging with the teeth 41 and capable of sliding on its shaft 50 in order to maintain engagement with the teeth as the disc 9 is rotated. The apparatus may be used in the multiplying machine described in Specification 505,114 which case the spiral is formed so that the rotation of the output member is proportional to the square of the rotation of the input member. Owing to the finite spacing of the teeth the movements of the crown wheel do not conform entirely accurately with the desired function when engaging with the central teeth of the spiral. This error can be substantially corrected by disposing the axis 50 to one side of the centre of the disc 9. When the apparatus is used for squaring a counter is secured to the input member and when the indication of this passes through zero it-operates reversing gearing in the mechanism between the input and output members in order to maintain the movements of the output member positive.

Abstract: 418,976. Photographic papers and fabrics. HALDEN & CO., Ltd., J., and HOLDEN, J., Rowsley Works, Reddish, near Stockport, Cheshire. March 4, 1933, No. 6598. [Class 98 (ii).] Photographic blue-print and diazotype papers and fabrics are treated, after sensitizing, with a waterproofing substance which impregnates the fibres of the paper or fabric but leaves the sensitized surface in condition for subsequent development &c. The waterproofing substance is applied in solution, or in a highly fluid molten condition with or without solvents. Thus, a paper sensitized with a ferro-prussiate solution is dried and treated, on either side, with a 5 per cent solution of paraffin wax in benzene. The waterproofing solution may contain a developing or intensifying agent e.g. Dichloramine T. Papers or fabrics so treated are specially suitable for the ferro-prussiate-gelatine " true-to-scale " process. Papers coated with a sensitive diazo solution may also be treated with a solution of paraffin wax in benzene and the solution may, in addition, contain a developing agent e.g. #.naphthol. Such diazotype papers may be developed with steam or water. Gelatine or other colloid may be added to the sensitizing solution to facilitate development. Other specified waterproofing substances are paraffin wax dissolved in petroleum spirit, molten wax, and solutions of chlorinated rubber or a cellulose ester e.g. collodion. The Provisional Specification refers also to bromide papers. Specifications 391,970 and 418,369 are referred to.

Title: Improvements relating to the catalytic desulphurisation of petroleum hydrocarbons
IPC: C10G67/06
Filed: 1951-03-20
Abstract: A petroleum fuel containing vanadium and/or sodium, particularly crude petroleum or petroleum residue, is contacted with bauxite at elevated temperature and pressure to remove vanadium and/or sodium, and then subjected to hydrofining in the presence of a cobalt molybdate catalyst consisting of the oxides of cobalt and molybdenum, preferably on a support, e.g. alumina. The full inactivity of the catalyst is thus reduced.  Preferably, the bauxite treatment is effected in two stages, first in the absence of hydrogen, when sodium is removed, and then with hydrogen to remove vanadium.  A tower containing a single bed of bauxite may be used, recycled hydrogen being admitted at an intermediate point to give optimum removal. Conditions may be those used in hydrofining, viz. 700-850 DEG  F. and 800-1,000 p.s.i.g. The spent bauxite may be used for a catalytic desulphurization, the finishing treatment of kerosines or for vanadium or sulphur recovery.  Figures are given showing the loss of activity of hydrofining catalyst by impregnating with vanadium and sodium, and the increase in life effected by pretreatment with bauxite. Specifications 710,342 and 729,301 are referred to.

Abstract: 730,276. Permutation locks. ROBINSON, H. H. June 19, 1952 [March 20, 1951], No. 6628/51. Class 44. A keyless lock comprises a bolt in the form of a rotatable disc A, Fig. 6, which is also mounted so as to be movable bodily in the plane of the disc and a keeper in the form of two co-axial and rotatable circular cup-like members D spaced apart, as at E, from each other and having their open ends facing one another, wherein the disc A is provided on each face adjacent its periphery with a series of laterally projecting cam portions B (see also Figs. 1 and 14) and the side walls of the cups D at their open ends are provided with a series of notches G, Fig. 2, each of dimensions to permit the passage of a cam portion B therethrough, the arrangement being such that when the disc A is moved towards the cups D, cam portions B in close proximity with each other engage unnotched portions of the cup side walls to urge the cups further apart against the action of springs until the cam portions are received within the cups, whereafter the springs return the cups to their original positions and thereby cause the cam portions to be locked within the cups. The locking action is effected by the flat rear faces C of the cam portions B, Figs. 1 and 14, engaging with the interior unnotched side wall portions of the cups. The springs are coaxial with the cups and urge them towards their positions of minimum separation. They also act torsionally so as to operate in conjunction with a ratchet for each cup, to rotate the cups to zero positions when the disc is retracted from therebetween. The ratchet normally engages in teeth around the periphery of the cups. A simple form of the invention is depicted in Fig. 3, wherein the keeper cups D are rotatably mounted in a fixed frame L and operable by an indexed knob (e.g. positioned on the outside of room) and the disc A is rotatably mounted in a frame H slidably mounted in a fixed frame J and is operable by an indexed knob (e.g. positioned on the inside of a room). A segment F of the bolt disc projects slightly from its frame H and this segment and its associated cam portions coact with the cups D when the frame H is slid towards the cups. The opening combinations of the knobs on the cups and disc are arranged to be the same. In the embodiment of Figs. 8 and 10 three discs A are arranged, one above another on parallel spindles in a slidable frame H and similarly three pairs of cups D are mounted one above another and rotatable spindles in a fixed frame L. Indexed knobs K and P are provided for the discs and cup pairs respectively. Springs M act both axially and torsionally in the cup pairs. The form of the invention shown in Figs. 8 and 10 may be modified by having three bolts and three cup pairs in each of the three lines depicted. In these circumstances the discs and cup pairs in each line are mounted on co-axial tubular spindles each provided with an indexed knob as described with reference to Figs. 11 and 12 (not shown).
