Title: An improved manufacture of organic oxides
IPC: C07D301/26
Filed: 1940-03-29
Abstract: 541,405. Organic oxides. STANDARD OIL DEVELOPMENT CO. March 29, 1940, No. 5671. Convention date, July 27, 1939. [Class 2 (iii)] Organic oxides are prepared by a process which comprises passing an olefin halohydrin into a rectification zone and contacting it with an alkali either just before or just after entering the tower. An additional supply of alkali is also injected from the top of the rectifying tower. The re-action products consisting of organic oxides and spent alkali are respectively withdrawn at the top and the bottom of the tower. It is preferred that a current of live steam be passed up the tower to carry upwards the vaporous products. It is also preferred that the alkali and the halohydrin should be mixed before entering the tower to avoid corrosion of the tower, and that the mixture should be heated by admixture of live steam to the re-action temperature. The preferred alkali is a slurry of calcium hydroxide, but other alkalies may also be used. Compounds mentioned include the oxides, hydroxides, carbonates and bicarbonates of the alkali and alkaline earth metals such as the carbonates and bicarbonates of sodium, potassium and calcium. In an example, ethylene chlorhydrin contained in the tank 1 passes to the tower 4 via the pipa 2 under pressure from the steam injector 3. Before entering the tower it is mixed with a stream of calcium hydroxide slurry from tank 7 fitted with stirrer 8, and supplied by pipe 11. The re-actants are distributed over the ceramic packing 5 in the tower by the distribution troughs 6. The alkali slurry is preferably preheated by admixture with steam from the line 12. The bottom section of the tower 4 is heated, and a hot inert gas is introduced to drive upwards all volatile products. Spent lime slurry is removed through line 14 to a settler 15 from which the supernatent liquor is withdrawn, and the unreacted lime is recycled. Additional slurry is supplied to the top of the column by the line 21. The vaporous re-action products are withdrawn by line 24 to condenser 25, and discharged into a hydration vessel 26 in which the olefin oxide is converted into glycol. Instead of pure ethylene chlorhydrin a mixture of chlorhydrins or other halohydrins may be used. It is stated that a particular advantage of the process of the present invention lies in the fact that the olefin oxide is quickly removed from the mixture of chlorhydrin and alkali, and polymerization and condensation re-actions are thereby avoided.

Title: Improved aiming apparatus for guns
IPC: F41G3/10
Filed: 1920-02-27
Abstract: 139,517. Schneider et Cie. Jan. 14, 1919, [Convention date]. Sights.-Relates to independent line of sight mechanism, having means for correcting for lateral and longitudinal inclinations of the gun carriage, of the kind in which a bracket carrying the sight is mounted on one of the gun trunnions and can be turned, for cross-levelling, about an axis parallel to the barrel bore. The invention consists in constructions wherein the tangent elevation drum, which is geared to one of the trunnions, is mounted directly upon the sight bracket, and is so arranged that it can be rotated from its zero position, while the gun remains horizontal, through an angle equal to the angle of sight, either by rotating the sight bracket to bring the sight on the target, or independently in indirect sighting, so that subsequent elevation of the gun by reference only to the tangent elevation drum elevates the gun to the algebraic sum of the angle of sight and tangent elevation, i.e. to the quadrant elevation. In the construction shown in Figs. 1 and 2, the bracket B is mounted to turn about a transverse axis on a bearing c formed on an arm C hinged to the trunnion E by an axle D parallel to the barrel bore. The bracket can be brought to the vertical position to correct for inolinations of the carriage by screws H and R. Within the bracket is the tangent elevation drum M, which is formed with a pinion m gearing with a toothed sector n carried by an arm N fixed to the arm C. After having been levelled, the bracket is rotated about the bearing c by means of the screw P through an angle equal to the angle of sight to bring the sight on the target, in direct sighting, or to bring a mark T, Fig. 1, against a predetermined division of a scale q, in indirect sighting. During this rotation of the bracket the drum M is rotated from its zero position by the pinion m rolling over the stationary sector n. When the gun is elevated, the axis L of the drum M remains stationary and the sector n moves, so the drum M is rotated, and the correct quadrant elevation is reached when the predetermined tangent elevation scale mark is opposite the mark O on the bracket B. In a modification, Figs. 7, 8, and 9, the sector n engages a pinion Q<1> fixed to a rotary plate Q carrying an angle of sight scale q. The drum M is frictionally held against the plate Q by Belleville washers X and normally rotates therewith, but can be independently rotated by an external handle M<2>. For indirect sighting, the tangent elevation drum is rotated relatively to the plate Q until the predetermined angle of sight division on the scale q is opposite a mark T on the drum. The gun is then elevated by reference to the drum M as before. For direct sighting, the bracket B is rotated to bring the sight on to the target by means of the screw R, the plate Q, and with it the drum M, being thereby rotated. Other modifications with different methods of gearing the arm C to the drum M or plate Q are described.

Abstract: 565,682. Etching. SNELLMAN, J. J. April 17, 1943, No. 6173. [Class 100 (ii)] [Also in Group XXII] A method of etching grooves consists in first etching a shallow groove 2, Fig. 2, coating the inside of the groove with an etching resist, removing the resist from the bottom of the groove to a predetermined width by a rotary needle 5 guided along the groove by the edges 4 of the groove, increasing the depth of the groove by further etching, and repeating the operations of coating, removing and etching until the desired depth is obtained. The method may be applied to the production of a punch 8 and co-operating die 10, Fig. 4, two grooves 7 and 9 offset from one another being etched from opposite sides of a piece of stock material. The parts are separated at the slightly overlapping part 11, and the ridges due to the etching removed and the two elements trimmed for correct co-operation. The angles at the bottoms of the grooves may have small fillets welded into them and spaced strips may be welded along the grooves to form guides for the elements. The first shallow groove may be formed by coating the surface with a resist, forming the design of the lines to be etched therein by a photographic method and etching. In a modification, a template is used to guide the needle for removing the resist, and at each stage a needle smaller in diameter than that used in the preceding stage is employed.
