Title: Contact sulphuric acid process
IPC: C01B17/79
Filed: 1927-02-14
Abstract: 266,007. Monsanto Chemical Works, (Assignees of Jaegar, A. 0., and Bertsch, J. A.). Feb. 15, 1926, [Convention date]. Catalytic agents, preparation and treatment of; sulphur trioxide, catalytic production of. - The oxidation of sulphur dioxide is effected with the use as catalysts of artificial zeolites containing vanadium in non-exchangeable form. Such zeolites may be used alone or in admixture with inert materials, such as pumice, magnesia, and metal alloys, and in the latter event the admixtures, which may be finely powdered or coarse, and preferably added before the zeolites have set. Binders such as alkali or alkali-earth sulphates, phosphates, chlorides, or nitrates, or sodium silicate, may be added if the amount of zeolite is insufficient to unite the inert materials into a homogenous structure, and such a structure, when formed, may be washed with sodium silicate solution to cause surface silicification. Alternatively, the set zeolites may be finely ground and applied as a thin layer to coarse granular carriers, and as carriers there may be used other substances acting catalytically in the reaction, such as titanium dioxide, ilmenite, titaniferous iron ore, bauxite, the oxides of chromium, copper, nickel, cobalt, and barium, and metals and metal alloys such as manganese, chromium, ferro- .chromium, ferro-vanadium, silicon-manganeseiron, aluminium-manganese-iron alloys, ferromanganese, ferro-titanium, ferro-tungsten, and ferro-nickel. In one axample, ammonium vanadate is heated with caustic soda solution and the solution is neutralized with hydrochloric acid and diluted. Sodium silicate solution is then added and the mixture is stirred and gradually warmed, small amounts of dilute hydrochloric acid being added from time to time. The mixture gradually yields a granular precipitate which is separated and dried at a temperature below 100‹ C. It may be used in the production of sulphur trioxide at temperatures of 430-450‹ C., and retains its activity up to 600‹ C. In another example, finelypowdered vanadium pentoxide is dissolved in caustic potash solution, it may be with the aid of a small amount of chlorine, and the solution is neutralized with hydrochloric acid and diluted. Potassium silicate, kieselguhr, and asbestos fibres are then added, and the mixture treated as described above. The product is prepared for use by treatment at 300-400‹ C. with a stream of air and then at 400-450‹ C. with dilute burner gases. In a further example, a mixture of vanadium pentoxide, silica, titanium dioxide, caustic potash, potassium carbonate, and borax is melted until carbon dioxide ceases to be evolved, whereupon the melt is poured into water and leached until the leaching water is free from boric acid. The product is prepared for use by a preliminary treatment with dilute sulphur dioxide. Other catalytically acting elements may be introduced into the zeolites by base-exchange.

Title: Drill Point Grinding Machines
Inventor: MEE JOHN KENNETH
IPC: B24B3/26
Filed: 1969-01-25
Abstract: 1,193,415. Grinding drills. Z. BRIERLEY Ltd. 25 Jan., 1969, No. 4337/69. Heading B3D. A drill point grinding machine comprises a motor-driven grinding wheel 11 and a workhead including a main housing 16 pivotally arranged on a support 14 and carrying a chuck 20 for a drill to be ground, the housing embodying a mechanism 21 which effects rotation of the chuck, axial reciprocation of the chuck, and swivelling of the housing, the axial reciprocation being effected by pivotal movement of a push bar 26 which extends chordally relative to a thrust ring 32 rotatably arranged on the spindle 18 of the chuck and engages a stylus 40 carried by the ring for ransmitting thrust from the push bar to the thrust ring. The support 14 can be adjusted about a pivot 15 along an aromatic track 13 and locked in position according to the taper to be ground on the drill's point. The main housing swivels relative to the support 14 also about the pivot 15 upon actuation of the mechanism 21 by a handle 22, the mechanism also rotating and axially reciprocating the chuck. The reciprocation is effected by rotation of a face cam 25 which is engaged by a follower 29 on one end of the push-bar 26 which has its other end mounted on a pivot 30 adjacent a bearing 17 for the spindle 18 of the chuck 20. The thrust ring 32 is rotatably adjustable on the spindle and bears by way of a thrust bearing against an end disc 19 on the spindle. The stylus 40 is located without a hole in the thrust ring and bears against the push bar so that as the face cam is rotated, the rocking of the bar 26 is imparted by the stylus to the thrust ring and, hence, the chuck. The amplitude of the reciprocation of the chucks is varied by rotating the ring 32 to positions determined by engagement of a spring-pressed plunger 35 with one or other of detents 38 formed in the ring to vary the distance between the stylus and pivot 30.

Patent GB-877230-A (GB)
Title: Process for dyeing mixed fabrics of cotton and superpolyester fibres
IPC: D06P3/84
Filed: 1958-02-12
Abstract: Mixed fabrics of cotton and polyester fibres are foularded or printed using a foularding solution or printing paste which contains a finely divided non-reactive pigment dyestuff, urea and a reactive organic dyestuff which, owing to the presence of one or more labile substituents easily capable of splitting up with the taking over of the electron pair of the bond, is capable of being fixed on cotton with the formation of a chemical bond, and the material is subjected, if desired after it has been partially dried, to the action of dry heat.  Preferred labile substituents are aliphatically bound sulphonyloxy groups (i.e. hydroxyl groups esterified by an organic sulphonic acid ester group), sulphuric ester groups and halogen atoms, especially chlorine atoms aliphatically bound or bound to a heterocyclic ring (e.g. pyrimidine, phthalazine or, especially, triazine).  Preferred reactive dyestuffs include those containing a 2-phenyl-4-chloro-1 : 3 : 5-triazine nucleus, and especially azo and anthraquinone dyestuffs containing a monochloro-1 : 3 : 5-triazine residue. Advantageously, the reactive dyestuff contains also at least one acid group, preferably one imparting solubility in water, e.g. an acylated sulphonic acid amide group, a carboxylic acid group or more especially a sulphonic acid group.  The foularding solution or printing paste preferably contains an acidbinding agent (e.g. alkali metal carbonate, phosphate, borate or perborate), and a more or less neutral salt (e.g. alkali metal chloride or sulphate), and the proportion of urea should be 1-5-% by weight, 1-10% being generally sufficient.  The dry heat treatment may be effected in a current of hot air at or above 100 DEG C., e.g. above 140 DEG C.  Where dyestuffs containing metallizable groups are used, the dyeing or print may be after-treated with an agent yielding a heavy metal, especially copper.  An example is given.
