Title: Slide valve controlled reciprocating piston engine of variable piston stroke
IPC: F01B17/04
Filed: 1942-06-19
Abstract: 554,487. Reciprocating pumps. SCINTILLA, Ltd. June 19, 1942, No. 8441. Convention date, July 29, 1941. [Class 102 (i)] [Also in Group XXIX] In a slide-valve controlled reciprocating pump, in which the piston - stroke is variable by means of a compound eccentric the adjustable outer eccentric is connected through epicyclic reducing-gear to another eccentric, that operates the slide-valve, in order to preserve the timed relation of the valve and the piston when the piston-stroke is adjusted. The inner eccentric 16, Fig. 1, of the compound eccentric that controls the working-piston 6, is fast on the engine-shaft 1 and supports the adjustable outer eccentric 17, which is embraced by a two-part collar 22, Fig. 2, slidable horizontally in a vertically sliding frame 23. A head 26 on the piston 6 is received in a boss 25 on the frame 23 and is retained by a spring and a screw-cap 28. The slide-valve 12 has a recess 14, which connects the working-cylinder 5 with admission and exhaust pipes 10, 11 alternately. The slide-valve is connected in the same manner as the piston 6 with an operating- eccentric 30 loosely mounted on the shaft 1. The eccentric carries epicyclic pinions 35, which gear with a toothed bush 31 fixed on the shaft, and with an internally toothed wheel 36 rotatable on the shaft. The outer eccentric 17 is connected to the toothed wheel 36 by pins 50, Fig. 3, supporting levers 51, which are connected at their adjacent ends by toothed segments 52, and have their outer ends connected by links 54 to the wheel 36. Since rotation of the outer upon the inner eccentric moves the total eccentricity through one-half the angle, the epicyclic pinions 35 are arranged to reduce the rotation imparted to the valveeccentric 30 to one-half that of the outer eccentric, so as to preserve the timing of the valve. The outer eccentric is adjusted by a disc 62 having a diametral groove 65, which is engaged by projections 66 on the eccentric. The disc 62 can be turned by means of a sleeve 59, which is rotatable on the shaft 1 and has a screw-thread of quick pitch engaged by a nut 60. The nut is slidable on guide-pins 57 by which it is constrained to turn with the shaft 1, and is moved axially by a lever 68 connected to a suitable operating-device.

Title: Process for the catalytic reforming of hydrocarbon mixtures of the gasoline type
IPC: B01J23/96
Filed: 1956-03-19
Abstract: 794,650. Reforming gasolines. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. March 19, 1956 [March 21, 1955], No. 8472/56. Class 2 (3). Hydrocarbon mixtures of the gasoline type containing less than 30 per cent by weight of naphthenes are catalytically reformed in the presence of at least an 8-fold molar proportion of hydrogen and a platinum catalyst on a carrier with acid properties at not less than 470‹ C. and not less than 10 atmospheres pressure, there being maintained in the reacting mixture a small proportion of water vapour not exceeding 0.03 per cent by volume, the degree of hydrocracking being such that at least 15 per cent by volume of the reformed product boils below the lower cutting point of the hydrocarbon feed. The proportion of water vapour is conveniently controlled by drying the recycle hydrogen-rich gas to the necessary extent before actually recycling or adding water or a water-producing compound, such as isopropyl alcohol or a butanol, the water vapour content being adjusted to be less than 200 mg. per normal cubic metre of recycle gas. Drying of the recycle gas can be performed with a glycol or derivative thereof such as diethylene glycol, and further drying if necessary with a solid desiccant such as bauxite, activated alumina or silica gel. Temperatures may be between 470‹ and 510‹ C., pressures between 10 and 100 atm., and L.H.S.V. between 2 and 5 litres/litre of catalyst/hour. With a pressure below 30 atm., a molar ratio of hydrogen to hydrocarbon of more than 10 : 1 is preferred with a water vapour content of less than 0.02 per cent by volume. The catalyst may be 0.1 to 1 per cent by weight of platinum on alumina, silica-alumina, or silica-magnesia and may be activated by the addition of up to 1 per cent by weight of fluorine or chlorine.

Title: Vitamin k derivatives
IPC: C07F9/12
Filed: 1958-03-18
Abstract: The invention comprises compounds of the formula: <FORM:0850352/IV(b)/1> where R* is a hydrogen atom or an acyl group and R\s2 is a halogen atom, a hydroxyl group, or a hydroxyl group in which the hydrogen p  atom is replaced by an alkali metal, and the process which comprises reacting a 1-monocarboxylic acid ester of 2-methyl-3-phytyl-1,4-naphthohydroquinone with phosphorus oxychloride to form the 1-monocarboxylic ester of 2-methyl-3-phytyl-1, 4-naphthohydroquinone-4-(dichloro) phosphate, reacting the latter compound with alkali to form a mixture of the mono-and-di-alkali metal salt of 1-monocarboxylic acid ester of 2-methyl-3-phytyl-1, 4-naphthohydroquinone-4-phosphate, reacting the latter compound with an inorganic acid to form 1-monocarboxylic acid ester of 2-methyl-3-phytyl-1,4-naphthohydroquinone-4-phosphate, reacting the latter compound with a concentrated aqueous alcoholic metal hydroxide to form a mixture of the mono,-di-, and tri-alkali metal salt of 2-methyl-3-phytyl-, 1, 4-naphtholydroquinone - 4 - phosphate and reacting the latter compound with acid to form 2-methyl-3-phytyl-1, 4-naphthohydroquinone 4-phosphate. Alternatively the 1-monocarboxylic acid ester of 2-methyl-3-phytyl-1, 4-naphthohydroquine-4-phosphate may be reacted with an alcoholic solution in the presence of an acid catalyst to form 2-methyl-3-phytyl-1, 4-naphthohydroquinone-4-phosphate.  Reaction with POCl3 may be effected in pyridine, triethylamine and other tertiary amines. Dilute aqueous alkali is utilised to form the alkali and dialkali metal salts.  Acidification with dilute acid produces the monocarboxylic acid ester of 2-methyl-3-phytyl-1, 4-naphthohydroquinone-4-phosphate. Claisen's alkali is then used to produce a mono-, di- or tri alkali metal salt thereof from which 2-methyl- 3 - phytyl-1,4-naphthohydroquinone-4-phosphate is obtained with aqueous acid.  Examples describe the preparation of 2-methyl-3-phytyl-1, 4-naphthohydroquinone-1-acetate-4-phosphate, 2-methyl-1, 4-naphthohydroquinone-4-phosphate, 2-methyl-1,4-naphthohydroquin-one-1-propionate-4-phosphate, and the corresponding 4-(dichloro) phosphates.  2-Methyl-3-phytyl-1, 4-naphthohydroquinone-1-acetate is obtained by condensing phytol with 2-methyl-1, 4-naphthohydroquinone-1-acetate in the presence of boron trifluoride etherate.

Title: Method and apparatus for removing solid impurities from fluid suspensions
IPC: D21D5/06
Filed: 1958-03-19
Abstract: 832,945. Presses for separating liquids from solids. OWENS, T. M. March 19, 1958 [March 28, 1957], No. 8771/58. Class 46. A method for removing solid impurities from fluid suspensions containing in addition to the impurities other useful solids is characterized in that the solids of the suspension are squeezed against a screen, having openings generally smaller than the impurities, with such force as to adhere the impurities relatively firmly to the screen, the useful solids remaining on the outer surface of the screen and being relatively non-adherent thereto, separating the useful solids from the screen in fluid suspension while leaving the impurities adhering to the screen, and separately removing the impurities from the screen. Incoming pulp 1, Fig. 1, flows from right to left towards a cylindrical screen 5 driven clockwise by contact with a rubber or like roller 10. Water and fine fibres pass through the screen perforations to the screen interior at A. The solids (of which the impurities from a small proportion) form a layer against the screen 5 which is squeezed at the nip of the screen and roller, and the remaining water is forced through the screen to the inner pool 15. The small head of water provided by the pool 15 is chosen to be sufficient to wash away the useful fibres on the discharge side at B, but insufficient to wash away the impurities, which have become adhered to, or embedded in the meshes of, the screen 5. The effluent level can be changed by an adjustable dam 22. Impurities are removed from the screen 5 to a channel 21 by high-pressure fluid from jets 20. In Fig. 3 (not shown), a screen belt runs over two pulleys vertically aligned, the lower one being an open framework occupying the position of the screen 5 in Fig. 1. Four jets (20), for water, steam or chemical cleaning agents are provided. In Fig. 4, the screen belt 5<SP>1</SP> passes over four pulleys. In Fig. 5 (not shown), the roller 10 is replaced by a horizontally-arranged belt while in Fig. 6, such a belt 10<SP>11</SP> is used with a screen belt 5<SP>11</SP>, the dam 22 in both these cases being dispensed with.
