Abstract: 531,051. Delivering cigarettes from hoppers. MULLER, J. C. July 11, 1939, No. 20149. Convention date, Aug. 9, 1938. [Class 78 (i)] In apparatus for delivering cigarettes from hoppers, of the kind in which a support at the point of emergence imparts a forwardly - inclined position to the cigarettes as they emerge, this inclination is imparted by a flexibly-yielding pivoted bar. Figs. 2 and 3 show cigarettes escaping from the lower part of a multi-column hopper c and being forwardly-tilted by the spring-pivoted member h. As the delivery chain d moves forward, the next spur e depresses the member h prior to engaging the ends of the cigarettes and pushing them along to the grooved shoot f. This arrangement is said to prevent fouling of the forward ends of the cigarettes with the adjacent side of the hopper at the time of delivery.
Patent GB-427386-A (GB)
Title: Refined ethers of polysaccharides and processes of making same
IPC: C08B11/22
Filed: 1933-07-17
Abstract: Carbohydrate ethers are refined by treating a solution of the ether with a precipitating or coagulating agent so as to cause precipitation of a part of the ether and separating the precipitate from the solution of the refined ether which remains. The precipitation may be effected by adding a salt such as sodium chloride or sodium sulphate, or by heating the solution.  In an example, sodium sulphate is added to an aqueous solution of ethyl, methyl, or propyl cellulose, the precipitate obtained is separated by filtration or centrifuging, and the refined ether separated from the clear solution by heating.  In another example, a combination of heating and addition of sodium sulphate is used to precipitate the ether from the unrefined solution.  Other examples are included in which the sodium sulphate is replaced by sodium chloride.  In a further example, to a solution of cellulose ether is added a small amount of egg albumen and the solution is partially precipitated by heating.  In other examples, the carbohydrate ethers subjected to the refining process are the ethyl, methyl, or propyl ethers of an ethylene glycol or propylene glycol ether of cellulose, and a simple or mixed starch ether.  In another example, a water-insoluble ethyl cellulose is partially precipitated from solution in aqueous alcohol by the addtion of a solution of sodium chloride, and the refined ether separated from the clear solution by precipitation.

Title: Improvements in operating gear for sluice gates
IPC: E02B7/36
Filed: 1919-08-16
Abstract: 149,840. Glenfield & Kennedy, and Borland, J. H. T. Aug. 16, 1918. Slwice-gates of the free-roller type are operated by a rope passing over a helically-grooved doubleconed pulley to a balance-weight in such a manner that when the gate is closed, the part of the rope attached to the weight leads from a groove of greater radius than that from which the part of the rope attached to the gate leads, and when the gate is open, the reverse is the case. A pulley B driven by spur-gearing G from a shaft H has a helical groove C round which the rope connected to the gate and a balance-weight passes, slipping being prevented by clips K. When the gate M, Fig. 2, is closed the rope L leads from the small part of the pulley up one cone to the balance weight N, so that opening is facilitated. On opening the gate, the part of the rope attached to it runs up one cone, while the part attached to the weight runs down the other cone, checking the movement of the gate, and facilitating closing. The balance-weight may be slightly heavier than the gate.

Abstract: 716,255. Gas turbine plant. ROLLS-ROYCE, Ltd. Aug. 14, 1952 [Aug. 28, 1951], No. 20320/51. Class 110(3) [Also in Group XXIX] The supply of fuel to a gas turbine engine is controlled in accordance with engine speed or ambient atmospheric pressure by a control mechanism comprising a nozzle adapted to direct a jet of pressure fluid into a receiving chamber and an obturator movable into the path of the jet to control the pressure in the receiving chamber, the nozzle and the receiving chamber being formed as a unit, and the obturator or the nozzle being rotatable about an axis so that relative rotational movement between the parts varies the extent to which the obturator obstructs the jet. In Fig. 3, the delivery pressure of a multicylinder swash-plate pump 52, supplying fuel to a gas turbine engine through a conduit 19 is maintained at a predetermined value which is proportional to the ambient atmospheric pressure. The conduit 19 contains a manually-operated throttle valve 50 and the fuel pressure upstream of this valve is regulated by adjusting the obliquity of the swash-plate 57 of the fuel pump by a spring-loaded servo-piston 59 the chamber 60b on one side of which acts as the receiving chamber of the control mechanism. The chamber 60b is connected by a conduit 60c to a divergent inlet 62 in a fixed part 63 also having a converging nozzle 66 fed from the conduit 19. Between the nozzle 66 and the inlet 62 passes the skirt of a cup 68 statically balanced about the axis of a spindle 70 on which it is mounted. The skirt has an axial slot 69 controlling the degree of obturation of the jet from the nozzle 66. Torques are applied to the spindle 70 by Bourdon tubes 71, 72 the coils of which grow in the same direction and the outer ends of which are anchored to a fixed part 65. The tube 71 is evacuated and subject externally to ambient atmospheric pressure through a passage 74. The tube 72 is subject internally to pump delivery pressure through a passage 78 and externally to pump inlet pressure through a passage 76 the latter passage also being connected through a further passage 77 with a chamber 64 containing the nozzle 66 and obturator cup 68. The invention is also shown applied to a gas turbine engine speed governor and such application is described with reference to Fig. 2 of Specification 716,254.

Title: Improvements in or relating to the production of pigmented compositions in organic vehicles
IPC: C09C3/00
Filed: 1937-07-22
Abstract: The transfer of pigments from aqueous to organic vehicles is promoted by the application of certain cationic surface-acting compounds, all of which have an aliphatic group of 8 or more carbon atoms attached to the positive radical of the compound. The said compounds are: (1) aliphatic quaternary ammonium or phosphonium hydroxides and water-soluble salts thereof; (2) water-soluble ternary sulphonium salts; (3) betaines; (4) inorganic acid salts of primary, secondary, or tertiary amines; (5) primary, secondary, or tertiary amines rendered water-soluble by the introduction of hydroxy or carboxyl groups other than by salt-formation with fatty or resin acids. Numerous examples of these classes are specified.  The substances are added to the pigments in small proportions at any stage after precipitation and before drying.  According to a typical example, 10 lb. of chrome orange pigment consisting essentially of basic lead chromate in the form of a washed press cake is mixed with 1 lb. of mineral spirits and 0,05 lb. of hexadecyl pyridinium bromide in the form of 10 per cent aqueous solution is added.  The pigment is immediately transferred to the mineral spirits with liberation of water.

Patent GB-589350-A (GB)
Title: Improvements in or relating to the manufacture of acetylenic alcohols
IPC: C07C29/42
Filed: 1944-10-23
Abstract: Acetylenic alcohols are produced by reacting acetylene under substantially anhydrous conditions and in the substantial absence of alkali metal hydroxides, with a ketone in the presence of an alkali metal alcoholate of a primary or secondary, saturated alcohol, containing only one oxygen atom in the molecule and which is not soluble in water in all proportions at room temperature. The reaction temperature is preferably between -15 DEG  C. and +10 DEG  C. Such alcohols are, e.g. sec-butyl-, n-butyl- and isoamyl alcohol and cyclohexanol, commercial amyl alcohol consisting mainly of 2-methyl-and 3-methyl-butan-1-ol being very suitable.  It is preferable to remove excess alcohol from the alcoholate, e.g. by heating in the presence of an inert organic liquid such as cumene, n-butyl formal, diisopropyl benzene and the dialkyl ethers of ethylene and polyalkylene glycols which has a boiling point at atmospheric pressure at least 50 DEG  C. higher than the alcohol of the alcoholate.  The process can be carried out cyclically, acetylene being passed into the substantially anhydrous solution of alcoholate in the high boiling inert liquid.  The alkali metal alcoholates may be prepared in a continuous manner by feeding the aqueous hydroxide and alcohol to the top of a fractionating column, removing water azeotropically and continuously removing the alcoholate solution in excess alcohol from the bottom of the tower.  The excess alcohol may be removed by feeding the solution with the inert solvent to the top of a fractionating column and distilling.  In examples: (a) acetylene is passed into a solution of potassium amylate free of excess amyl alcohol, in the ethyl butyl ethers of diethylene glycol at 0 DEG  C., acetone is then added whilst continuing the passage of acetylene until absorption ceases.  Water is added to hydrolyse the potassium alcoholate of the acetylenic alcohol, the latter being extracted with amyl alcohol.  The potassium hydroxide solution is recovered and used together with the residue of amyl alcohol and the inert liquid remaining after distilling off the acetylenic alcohol, to prepare a fresh batch of potassium amylate; (2) potassium amylate in diethylaniline is saturated with acetylene and acetone vapour mixed with acetylene introduced; the product as in (1) is 3-methyl-but-1-yn-3-ol.  Methylethyl-, methyl propyl-, diethyl-, methyl-amyl-and di-isopropyl-ketone and cyclohexanone may also be employed.  Specification 304,585, [Class 2 (iii)], U.S.A. Specification 2,161,191 and German Specification 291,185 are referred to.
