Filed: 1954-11-29
Abstract: The invention comprises 1-alkyl-5-dialkyl or -5-dialkenyl- or -5-alkyl-5-alkenyl-thiobarbituric acids (wherein the alkyl group in position 1 contains 3 to 5 carbon atoms and the alkyl or alkenyl groups in position 5, which may be the same or different, contain not more than 6 carbon atoms), their salts (e.g. sodium salts), and their preparation by condensing an appropriately disubstituted malonic acid di-(1-4C)-alkyl ester with an N-alkyl thiourea, or by condensing an appropriately disubstituted cyanacetic acid (1-4C)-alkyl ester with an N-alkyl thiourea with subsequent dilute mineral acid hydrolysis of the resultant 4-iminothiobarbituric acid.  The condensations may be effected by refluxing the reactants in a solution of a sodium alkoxide in a 1-4C aliphatic alcohol.  Examples describe the preparation by the first of the above methods of thiobarbituric acids in which the 1-substituent is selected from n- and iso-propyl, n-, iso- and sec.-butyl and isoamyl, and the 5-substituents are selected from 2-methyl-n-butyl, allyl, ethyl, sec.-butyl, n-propyl, iso-butyl and methyl, and by the second of the above methods of 5-(isobutyl)-5-allyl-1-n-propylthiobarbituric acid via the intermediate 5 - (isobutyl) - 5 - allyl - 1 - n - propyl - 4 - iminothiobarbituric acid.  In a further example, 5-isobutyl-5-methyl-1-n-propylthiobarbituric acid is converted into its sodium salt by the action of sodium ethoxide in ethanol. The products are useful as general an sthetics.  According to the Provisional Specification, the 1-substituent may be any alkyl group containing more than two carbon atoms.

Title: Process and apparatus for separating phosphorus from gases
IPC: B01D47/06
Filed: 1958-10-29
Abstract: <PICT:0865731/III/1> Gas containing phosphorus vapour from a phosphate-reduction furnace is sprayed with water in a first zone so as to cool the gas to a temperature of 55-65 DEG C., and precipitate not more than 99.5%, preferably 95-99.5%, of the phosphorus as a liquid, and in a second zone so as to cool the remaining gas to a temperature below the m.p. of phosphorus, and precipitate substantially all of the remaining phosphorus as a solid.  The phosphorus precipitated in the second zone may be recovered by melting with live steam. The water sprayed to each zone preferably has a temperature of below 15 DEG C., e.g. 5-10 DEG C.  As shown phosphorus-containing gas from the first zone, e.g. at a temperature of 55 or 60 DEG C., is injected from a line 21 into a second zone constituted by a tower 2, and is sprayed with water from nozzles 3. The resulting cooled gas, e.g. at a temperature of 10 DEG C., is passed through a pipe 9, the inlet of which is sprayed with water from a nozzle 22, a centrifugal separator 10 and a droplet separator 13, a phosphorus-water mixture being recycled to tower 2 via lines 24, 26 and 15.  An aqueous phosphorus sludge separates in a lower conical part 4 of tower 2 and passes through a valve 6 into a sump 5 provided with steam line 7, molten phosphorus line 8, and deaeration line 25. Steam may be injected into sump 5 for a period of 2-3 hours. At intervals of 2 or more days.  Supernatent water, e.g. at a temperature of 30 DEG C., is recycled via line 16, steam jet refrigeration plant 18, and line 19, together with make-up water from line 20, to nozzles 3 and 22.

Title: Improvements in or relating to continuous combustion heating apparatus adapted for operation with liquid fuels
IPC: F23C99/00
Filed: 1932-12-09
Abstract: 411,529. Vapour burning stoves. SVENSKA AKTIEBOLAGET GASACCUMULATOR, Lidingo, near Stockholm. Dec. 9, 1932, No. 34974. Convention date, Feb. 13. [Class 75 (i).] In a continuous combustion heating-apparatus liquid fuel falls freely into a carburetting chamber separate from the burner and is vaporized and mixed with a dilution gas or gas mixture entering the chamber in the same direction as the liquid fuel, which gas or mixture will not condense at the temperature inside the chamber and forms with the fuel vapour a mixture which is non-inflammable or is not subject to preignition as a whole within the range of temperatures in the chamber. Fig. 1 shows an oil-fired domestic cooker of the heataccumulating type in which the liquid fuel falls freely, preferably in drops, from a pipe 1 into a carburetting chamber 2 which is in good heat-conducting connection with, and may be partially formed in, the cast iron heat-accumulating block 3. The fuel is rapidly vaporized in the chamber 2 and is mixed with dilution gases poor in oxygen, which gases are drawn from the flue 9 through a duct 13 and after being cooled in a chamber 14 pass through a pipe 15 to a chamber 24 surrounding the fuel delivery nozzle on the pipe 1. The mixed gases then pass with air drawn through a pipe 5 from the atmosphere through a mixing passage 4 and a pipe 6 to a burner 7 arranged below the combustion chamber 8 in the heat-accumulating block 3. An injector nozzle may be provided in the mixing passage 4 to assist the flow of the gas mixture and the chamber 14 may be cooled by a waterjacket. The upper surface of the block 3 may form a hot plate and is provided with a heat-insulating cover 12. In a modification the mixing passage is formed with baffles and a throttling device is provided in the flue 9 to produce an excess pressure which causes the flue gas to pass to the carburetter chamber. A small quantity of oxygen may be supplied through the chamber 14 to prevent the formation of coke in the chamber 2. A ring of asbestos or other heat-insulating material may be interposed between the burner and the block 3. Fig. 5 shows a burner 31, 32 supplied with air through a pipe 34 and with fuel vapour mixed with a diluent gas from a carburetter chamber 30. The fuel is supplied through an upwardly inclined pipe 40 having a branch pipe 42 fitted with a pin 43 on which the oil collects in drops which fall into the chamber 30 and are immediately vaporized. The diluent gas which may be air is supplied through a pipe 25 surrounding the pipe 40 and enters the chamber 30 through a chamber 24.

Title: Improvements relating to centrifuges
IPC: B04B11/08
Filed: 1957-11-12
Abstract: 872,605. Centrifugal strainer separators. GUTEHOFFNUNGSHUTTE STERKRADE A.G. Nov. 12, 1957 [Dec. 6, 1956], No.35291/57. Class 46. A spindle 7, Fig. 1, carrying a plough 8, Fig. 2, is lowered by a rack on the spindle engaged by a pinion 6 connected to a bevel wheel 5a driven by a bevel wheel 5 loose on the driven shaft of a clutch 2 but engaged for the time being, Fig. 1, by a grooved control collar 3 which has bevel-engaging pins 4a (see Fig. 2), and is slidably secured to the driven shaft. When a notch 13 on the shaft comes opposite a locking pin 12 articulated to a forked lever 11, (the plough 8 having just entered the drum 9), the lever 11 is rotated slightly about a pivot 11a by a spring 14, whereupon the control collar 3 is disengaged by the forked end of the lever from bevel wheel 5 to prevent any further downward movement of the spindle 7 and the locking pin 12 engages the notch 13 to hold the spindle, Fig. 2. The control collar 3 is now in engagement with a clutch consisting of dogs 15-17, loosely mounted on the driven shaft, the lowermost being secured to a bush 18 in turn secured to a fixed bracket 19. The clutch 15-17 now acts to hold the rotor of the motor 1 fixed, whereupon the stator, (not shown), revolves, and with it the housing 21, (carrying spindle 7), about a bronze bushing 20 which is coaxial with the motor. The plough 8 is thus swung into contact with the drum 9, Fig. 2. When the housing 21 is prevented from further movement by engagement of a lug 22 on the housing 21 with one of two stops 23 on bracket 19, the frictional force between the top and middle dogs 15, 16 is overcome, and dog 15 in riding up on dog 16 lifts the control ring 3 to the Fig. 1 position, whereupon the locking pin 12 is withdrawn from notch 13, and the control ring 3 engages with the bevel wheel 5 to cause the spindle 7 to be lowered further. The ring 3 is held up by spindle 7 and lever 11, and dog 15 drops back. The plough now empties the drum from top to bottom until a limit switch reverses the motor, whereupon the plough completes emptying from bottom to top until notch 13 reaches pin 12 again. Housing 21 now swings back to its former position until lug 22 reaches a second stop 23, whereupon dogs 15 and 16 ride up on dog 17 to withdraw pin 12 from notch 13 and permit upward movement of the spindle 7 to be continued to the Fig. 1 position.

An axially-acting expander adapted to cooperate with at least one thin flat piston ring 6, is of sinuous outline and has areas 4, Fig. 1, engaging the ring 6 and separated by gaps 5, the sinuous outline being formed by bending the expander around radial lines and the ratio between the arc length corresponding to the boaring areas and the arc length of the gaps being greater than one. As shown in Figs. 5 and 27, the expander, which may be made of steel strip or wire, cast iron, copper, brass or an elastic material, is arranged to act on several rings 6. disposed in a groove 9 of a piston 10, a radially-acting expander 7 also being provided. As shown in Figs. 9 and 13, the expander may be made of a number of separate parts 21 and assembled on the rings 6 by various types of hook arrangements 22 and 25. If desired, the gaps may be closed as shown in Fig. 23. Collapse of the expander is restrained by the provision of enlarged loops 33, 34 or by projections 36, Fig. 25, which are arranged to engage the loops 3 or a ring 6. The expander may be provided with apertures, preferably on its base, so as to facilitate flow of oil into the piston groove. The rings 6, in their unstressed condition, may be frusto-conical and have concave or convex faces; furthermore, the edges may be straight or rounded off or, alternatively, provided with serrations to facilitate flow of oil during the running-in period of the piston.

Title: Improvements in or relating to arrangements for correcting deflection errors in a cathode-ray tube
IPC: H01J29/74
Filed: 1966-08-10
Abstract: 1,141,624. Cathode ray tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 10 Aug., 1966 [13 Aug., 1965], No. 35801/66. Heading H1D. Orthogonality errors of the electrostatic deflecting system of a cathode ray tube are corrected by means of a quadrupolar magnetic field. The invention is applied to tubes having electrostatic systems for providing deflections in orthogonal directions CC, DD. A quadrupolar field produced e.g. by four permanent magnets 9, 10 is aligned so that the asymptotes of the field coincide with the directions CC, DD. Except at the centre, where there is zero intensity, the field may be represented by vectors 11 and the consequent deflections by vectors 12. The effect of the field is to rotate the original deflection directions to the non- orthogonal directions C<SP>1</SP>C<SP>1</SP>, D<SP>1</SP>D<SP>1</SP>. Conversely, non-orthogonal deflections may be made orthogonal. Two diametrically - opposed magnets suffice to produce the necessary field. Saddleshaped coils may be used instead of magnets. If a pair of diametrically-opposed poles are unequal in strength a bi-polar field is superimposed upon the quadrupolar field. The strength of this field may be used for centring the image in one or both orthogonal directions.
