Title: Improvements in sealing devices for rotating members
IPC: F16J15/34
Filed: 1940-02-28
Abstract: 537,932. Stuffing-box substitutes. SEALOL CO. Feb. 28, 1940, No. 3723. Convention date, Oct. 3, 1939. Addition to 513,748. [Class 122 (v)] In the device of the parent Specification, in which a sealing-member has surfaces acted on in opposite directions by the pressure of the fluid, and the effective pressure is determined by the relative area of the surfaces, the fluid is arranged to act in opposite directions on a sealing-ring, which can slide without rotation on the shaft to be sealed, and also on a sleeve, which can slide on and turn with the shaft and presses the ring against an abutment. The sealing ring 12, Figs. 1 and 4, slides on a collar 15, which is fixed to the shaft 14 and serves as an abutment for the ring. A sleeve 16, rotatable with the shaft, slides on a tubular member 17 splined on the shaft, and is pressed by springs 27 against the ring. Sealing-surfaces are thus formed between the sleeve and the ring, and between the ring and the collar 15. Oil may creep between the ring and the collar to annular grooves 74, 78 between the collar and the ring and between the ring and the sleeve respectively. Oil also reaches a radial surface 83, Fig. 4, on a flanged part of the sleeve. The effective sealing-pressure depends on the relative areas of the radial walls of the grooves 74, 78 and the radial surface 83. If the walls of the groove 78 are larger than those of the groove 74, and the surface 83 still larger, there will be a progressive application of pressure on the abutting surfaces. If the surfaces are of equal area, the fluid pressures will be balanced, and the sealing-pressure will be that of the springs 27. The tubular shaft 14 may have low and high pressure sides 31, 32 separated by a partition 30, and oil may be withdrawn from the low-pressure side and returned to the high-pressure side by a pump. The oil passes to the pump through a bore 38, Fig. 1, in the shaft, passages 35, 48 in the sleeve 16 and the sealing-ring and a bore 50 in the shaft-casing 11. The bores 38, 50 contain spring- pressed sleeves 41, 54, which effect seals with the sleeve 16 and the sealing-ring 12. The sleeve 54 has a flanged portion of such dimensions that the fluid pressures acting on the sleeve are balanced, and the sleeve is seated only by its spring 55.

Abstract: 285,642. Abbott, G. J. Feb. 10, 1927. Milling-machines.-In a milling-machine for cutting radial grooves in plane or conical discs -such as are used for the opposing faces of expanding pulleys, the work is oscillated relatively to the cutter about its centre and is simultaneously reciprocated perpendicularly to the length of the groove being cut and fed parallel to the groove. The cutter C is carried by a stationary shaft C<1> and the work B is mounted on a rotary table A which is inclined so as to make one generator of the cone horizontal, the table being rotatable on a transverse slide E traversable in guides E<1> on a slide F movable perpendicularly to the slide E. In operation, the cutter is rotated by a chain T which passes over sprockets U, V and also engages a wheel M' which rotates a crank L driving connecting rods J<1>, K<1>, the former serving to oscillate, through an adjustablethrow crank J, a screw H engaging a nut on the slide E and the latter being connected at an adjustable radius to a toothed sector K engaging a pinion on a shaft P carrying a worm S meshing with a worm-wheel S<1> attached, to the work-table A. The oscillation of the table caused by the worm S is adjusted to the width of groove required in the work and the reciprocation of the slide E by the screw H is made equal to the thickness of the cutter in order to ensure both sides of the groove being truly radial, the movements of oscillation and reciprocation taking place in opposite directions. Springs E<2> serve to assist in returning the slide E and to take up backlash in the screw and nut H. The pinion on the shaft P is connected thereto by a plunger R<1> on an arm R and an index plate O to provide for spacing the grooves on the work, and the slide F is fed (by means not shown) to traverse the cutter along the groove. The cutter has a projecting part 6<2> for producing the groove and side portions for machining the surface of the work between the grooves, the profile of the part C<2> being adapted to the shape of groove required. According to the Provisional Specification one connecting rod only is employed and is attached at a fixed radius to the crank L and at an adjustable radius to the sector K.

Title: Improvements in the catalytic conversion of mixtures of carbon monoxide and hydrogeninto valuable organic compounds containing more than one carbon atom in the molecule
IPC: C07C29/151
Filed: 1928-02-09
Abstract: 313,467. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 9. 1928. Addition to 266,405. Alcohols; acids; esters ; ketones; hydrocarbons. -In the production of hydrocarbons and oxygencontaining organic compounds having more than one carbon atom by catalytic interaction of carbon monoxide and hydrogen under pressure, the operation is effected in a circulatory system using a gas mixture containing only the reactants in the requisite proportions for the reaction, and extraneous gases are introduced into the system to the extent of at least 40 per cent by volume. The extraneous gases, of which methane, ethane, nitrogen and rare gases are specified, may be introduced prior to, at the commencement of, or during the reaction. By the use of the said gases, superheating with consequent deposition of carbon on the catalyst is minimized. Other measures for eliminating the excess of reaction heat, e.g. cooling the catalyst tubes by means of the cold reaction mixture, may also be employed. The process is particularly applicable to the production of liquid hydrocarbons using catalysts containing iron and cobalt, and to the manufacture of acids, esters, alcohols, ketones, &c. by the aid of catalysts containing iron, cadmium and copper, or potassium, zinc and chromium, or zinc, chromium and manganese. The reacting gases are preferably freed from carbon dioxide. sulphur compounds and iron carbonyl. According to the examples, (1) a mixture of carbon monoxide and hydrogen containing 65 per cent methane and 10 per cent nitrogen is circulated under pressure over a catalyst comprising iron, copper and potassium carbonate, and yields a mixture of liquid and gaseous hydrocarbons; the reactants consumed are replaced by the continuous introduction of water gas ; (2) a carbon monoxidehydrogen mixture containing 55 per cent methane and 5 per cent nitrogen is circulated under pressure through a tube, lined with manganesecopper and mounted in a metal bath, which contains a catalyst prepared by precipitating mixed iron, copper and cadmium nitrates with potassium carbonate, washing, drying and granulating: the entering gases are preheated by passage through a tube within the catalyst tube; fresh gas consisting only of carbon monoxide and hydrogen is continuously introduced; the product consists of liquid hydrocarbons together with ethyl and higher alcohols, and esters; (3) a carbon monoxidehydrogen mixture containing 40 per cent methane and 10 per cent nitrogen is circulated under pressure over a catalyst prepared by fusing potassium bichromate with manganese and zinc oxides; water gas is used as replenishment gas; the product consists of methyl, isobutyl and higher alcohols, and cyclic ketones.
