IPC: F02M1/16
Filed: 1924-02-26
Abstract: 213,235. Ducamp, A. J. March 23, 1923, [Convention date]. Addition to 210,995 and 212,246. Spray carburettors. -The parent Specification describes a carburettor comprising a main jet of comparatively large bore opening freely into the choke tube and having a single calibrated constriction or nozzle at a point below the fuel level, and a tube of larger diameter than said jet arranged coaxially therewith, said tube being freely open to the atmosphere at one end but closed at the other end with the exception of a calibrated aperture or compensating passage piercing the wall of said jet at a point below the calibrated constriction or nozzle and one or more small apertures piercing the wall of said jet above said constriction. The invention consists (1) in forming the calibrated aperture h in a member v separate from and below the tube c in which the constriction a is formed, such member v containing also a passage w in line with the constriction a; (2) in extending the main jet tube c by an integral or separate part x to such an extent that it touches the cone formed by the axes of the air passages t described in Specification 212,246. The effect of these modifications is that air is admitted through passage h to the entrance of passage w only at high speeds, overflow from the nozzle is prevented and the emulsion issuing from the tube c is brought more effectively under the action of the air through passages t.

Abstract: 853,834. Tea extracts. UNILEVER Ltd. Feb. 13, 1957 [Feb. 13, 1956], No. 4999/57. Class 129 An aqueous tea extract containing at least 3 % by weight of tea solids is evaporated under a controlled vacuum at a temperature of 65 ‹C. or less to remove 5 to 30 % by weight as dilute aroma, the dearomatized extract being concentrated while the dilute aroma vapours are fed to an intermediate point of a fractionating column at least atmospheric pressure, the base of the column being heated to strip aroma from liquid flowing down the column and force it out through the top as vapour which is returned as reflux to the column to maintain a high concentrate of the aroma in the condensate, a minor proportion of the condensate being removed as concentrated aroma which is mixed with the concentrated extract. Black, green or semifermented teas may be used and the leaves may be whole, comminuted or powder. As shown tea leaves are contracted with water in a counter current extractor 10 at an elevated temperature for sufficient time to produce an extract of at least 3 % and generally 3À5 to 5 % soluble tea solids. Liquid from extractor 10 passes through pipe 16 and strainer 21 or a centrifuge and then through either down flow heater 22<1> or upflow heater 22 into the chamber 25<1> of vacuum flash evaporator 25. In chamber 25<1> where the pressure is not greater than about 125 mm. of mercury and the temperature is 40 to 65 C., 5 to 30 % of the dilute extract is removed. The aromatic constituents leave the chamber through pipe 26, are condensed in condenser 27 and collected in vessel 28 connected through a valve 29 to a vacuum source, valve 29<1> only being opened if the vacuum diminishes. The unevaporated liquid is collected in a tank 31 or is withdrawn at a constant rate with a pump and contains about 4 to 6 % solids. The dearomatised extract is fed through a pipe 36 to the vaccum concentrator 37, through either upflow heater 38<1> or down flow heater 38 and may operate at a pressure of 625 to 725 m.m. of mercury and 40 to 65 C. The extract leaving concentrator 37 contains about 25 to 45 % solids and flows through pipe 40 to vessel 41. The aromatic constituents flowing through pipe 30 are pumped through pre-heater or vaporizer 46 to an intermediate point of fractionating column 47 which is heated at the base. The liquid flowing down the lower section of the column is stripped by using vapours from the reboiler. The vapours are condensed at 50 and collected in vessel 54 and most is returned to the column through pipe 51, the remainder flowing through pipe 52 to vessel 41 where it is mixed with the concentrate of the dearomatized extract. Specific examples are given using different types of tea. Specification 575,118 is referred to.

Title: Improvements in or relating to the production of dichlorbutenes
Inventor: CAUDLE PETER GRAINGER
IPC: C07C21/09
Filed: 1963-02-09
Abstract: Dichlorobutenes are produced by reacting chlorine with excess butadiene at elevated temperatures in the vapour phase, the reaction product is cooled and fed to an intermediate point of a distillation column in which unreacted butadiene and hydrogen chloride are separated as an overhead fraction, most of which is recycled, the remainder is contacted with cooled dichlorobutenes to extract the butadiene and the solution thus obtained is fed to an intermediate point in the distillation column.  The amount of overhead fraction contacted with dichlorobutenes varies inversely with the amount of hydrogen chloride in the fraction.  The liquid dichlorobutenes are obtained from the base product of the distillation column, and are cooled to - 30 DEG  to 0 DEG  C. Specification 798,028 is referred to.

Title: Manufacture of condensation products from urea or its derivatives and formaldehyde
IPC: C08G12/12
Filed: 1926-03-01
Abstract: 249,101. Soc. of Chemical Industry in Basle. March 10, 1925, [Convention date]. Condensation products from formaldehyde and urea &c.-In the manufacture of condensation products from urea or its derivatives and formaldehyde, the first water-soluble condensation product made in the usual manner from one molecular proportion of urea to at least two molecular proportions of formaldehyde is mixed with a quantity of urea sufficient to bring the proportion of urea to formaldehyde to a value greater than 1.05: 2 the mixture is then concentrated and either allowed to stand for some time or is greatly heated in order to harden. Prior to the hardening a small amount of an acid substance such as sulphuric or phosphoric acid and ammonium chloride or sulphate is added. The urea and acid substance may be added to the soluble condensation product before or after or at any stage of the concentration: moreover, the addition of the urea permits of the ready separation of the greater part of the water. When the molecular proportion of urea to formaldehyde in the product is small, e.g. 1.1 to 2, the products are clean; as the proportion of urea increases, the products become milky and finally like porcelain. Before hardening, the mass may be incorporated with fibrous, pulverulent or liquid filling materials, colouring matters, or agents conferring elasticity; pyridine is mentioned. Examples are given of the production of condensation products from formaldehyde and urea.

Abstract: 692,470. Spray guns. SCHONHOLZER, W. March, 7. 1952 [March 13, 1951], No. 6038/52. Class 69(iii) In a spray gun for spraying semi-fluid material such as paint, varnish or oil, with or without mixtures of fibres &c. supplied under pressure to a bore 12, while compressed air is supplied from a duct 33 the nozzle has three concentric discharge openings, an inner opening 50, an intermediate opening between 9 and 10 and an outer opening 45. The air supply is regulated by a trigger 18 which retracts a hollow needle 11 and also by a cock plug 21 which can be adjusted to one of three positions 120 degrees apart whereby the air is controllably delivered to one or other of the discharge openings, to give the desired kind of coating without formation of a mist. The compressed air may thus be directed to flow either through the inner opening 50, or through the outer annular discharge opening 45 or through both 45 and 50, the paint &c. coming from a third opening between 9 and 10 when 10 is retracted. When the cock plug 21 is rotated by its handwheel 29 to the position Fig. 4a to discharge air through 45 only, normal spraying is obtained, if positioned to discharge air through both 45 and 50 a fine atomization of paint &c. is produced and if through 50 only the atomization is only slight and is used for painting e.g. buildings without dispersion. The nozzle 6, its mouthpiece 9 and the insert 4 can be exchanged for similar parts to suit other material to be sprayed. The quantity of paint &c. delivered from between 9 and 10 is regulated as desired by the trigger retraction of the needle 11. A slide valve or rotary valve could be provided instead of the rotatable cock 21.
