Title: Improved automatic device for changing the weft for mechanical weaving looms
IPC: D03D45/20
Filed: 1923-03-17
Abstract: 197,304. Antoine, A. May 4, 1922, [Convention date]. Shuttles, changing weft carriers in, automatically.- The magazine 16, Fig. 1, provided with a passage 17 for the heads of the cop spindles &c. and with a supporting-plate for the bodies of the cops &c. 18, 18<a> oscillates about a spindle 15 during the replenishment, its lower part accompanying the lay, whilst the pusher or transferrer 22 is mounted on a spindle 24 on an arm 7 pivoted on a spindle 3, so as to move downwards in a slide channel 23 and act on the lowest cop &c. 18 in the magazine to transfer it into the shuttle. The cops &c. are introduced from an interchangeable reserve 19. In one form of the apparatus, a lever 11 on a shaft 12, oscillated by the weft-fork or feeler mechanism, raises a lever 8 pivoted on a vertical lever 4 into the path of the advancing lay. The lever 4 is thus oscillated and causes the arm 7 to be oscillated, whereby the magazine is oscillated so as to come into the path of the shuttle-box 25 on the lay. The magazine is thus oscillated by, and its bottom part accompanies, the advancing lay, the pusher 22 being gradually depressed to transfer the cop &c. In another form, a spring 33, Fig. 2, on a lever on the shaft 12 rocks a lever 32 pivoted on the spindle 15 whereby a lever 28 provided with a collar 30 loosely surrounding the magazine 16 is oscillated, so that a projection &c. 28 is moved into the path of a part 35 on the lay, and the magazine is thus oscillated. The lever connected to the pusher is in this latter modification mounted on the same pivot as before, but on the opposite side of the magazine, out of the path of the parts actuated by the weft-fork mechanism &c.

Title: Method of automatic manufacture of closed internally sterile hollow bodies and device for carrying out the said method
IPC: B29C49/00
Filed: 1975-02-25
Abstract: 1457099 Blow moulding sterilized containers E P REMY & CIE 25 Feb 1975 [22 March 1974] 7872/75 Heading B5A Internally sterile sealed containers are made by a process of extrusion blow moulding a tubular parison 3 while a predetermined pressure of sterile gas is applied to the interior of the parison and a vacuum is applied to the blow mould cavity 6 surrounding the parison, in which the extruded parison is sealed at one end and introduced into the blow mould 1 under an internal gas pressure p 1  of little more than atmospheric, the gas pressure is increased to a relatively high value p 2  to immediately blow the parison, whereupon the pressure is dropped to a holding pressure p 3 , and after closing the other open end of the blown parison the pressure p 1  is restored in the following parison from which the blown parison is separated before it is discharged from the mould. The ends of the parison are sealed by members 4 and severed by a knife 5. The three pressures of heat sterilized gas are applied from separate lines through valves 7a, 8a and 9a which are automatically controlled to give immediate change over from pressure p 1  to p 2  but to provide a delay between cutting off p 2  and applying p 3 . Thus if a container is pierced and gas at the higher pressure p 3  becomes contaminated by contact with the mould, it will have time to be drawn off through openings 11 of the vacuum line 10 and will not flow back into the sterile gas line 15 when the lower pressure p 2  is applied.
Patent GB-567114-A (GB)
Title: Improvements in and relating to the production of amines
Filed: 1943-05-18
Abstract: A process for the recovery of amines from aqueous solutions, obtained by the reaction of ammonia and one or more aliphatic monohydric alcohols containing up to eight carbon atoms, said solutions containing carbonates of ammonia and the amines in addition to the amines, comprises providing in the said aqueous solution an alkali metal hydroxide and almost immediately driving off part at least of the amines as vapour by applying heat and/or lower pressure to the solution.  The deposition of ammonium and amine carbonates in the apparatus used for separating the amines, particularly in the lines connecting it to the the vapour - producing apparatus, is thereby avoided.  The quantity of alkali metal hydroxide provided should be sufficient to fix the whole of the carbon dioxide present in the aqueous amine solution.  The recovered amines may be separated by known means.  In example (1), an aqueous amine solution prepared from methanol and ammonia, containing ammonia, methylamines, methanol, dimethyl ether and carbon dioxide is fed into the column of a still operating at 50 lbs. gauge pressure.  A solution of caustic soda is injected into the feed so that mixing occurs prior to the mixture entering the column.  The ammonia and amines distilled off are free from carbon dioxide, whilst the purge from the boiler is free of amines.  A similar solution distilled without addition of alkali hydroxide results in rapid choking of the still; (2) an aqueous amine solution comprising ammonia, ethylamines, ethanol, ethyl ether, ethylene and carbon dioxide, prepared by reacting ethanol and ammonia, is similarly treated; in a first stage ammonia, mono- and di-ethylamine, ether and ethylene are stripped off, and then the residue fractionated to obtain di- and tri-ethylamines; no choking of the still occurs.

Title: Improvements relating to carbonisation processes
Inventor: WILLIAMS FRANK ARCHER
IPC: C10B7/06
Filed: 1954-03-18
Abstract: 783,179. Carbonizing solid fuel. MINISTER OF FUEL & POWER. March 7, 1955 [March 18, 1954], No. 7886/54. Class 55 (1). In a process in which material is carbonized by being passed continuously in the form of a thin layer through a chamber, the material is densified by being subjected, during its passage through the chamber to pressure from a reciprocating ram. As shown, coal is fed from a hopper 2 on to a plate 7 supplied with hot air through duct 6 and apertures 7a. The travelling grate 3 carries at intervals a series of hinged plates 9 which are spring biased to a position normal to the grate surface. A reciprocating ram 10 operated from an hydraulic cylinder (not shown) acting through a ramrod 11, is correlated with the movement of the grate 3 so that the ram 10 is withdrawn, as shown, as each plate 9 travels around the roller 4a at the intake end of the chamber 1. The working stroke of the ram 10 gives a succession of short pushes to the coal on plate 7 and when a fresh plate 9 is about to emerge from under plate 7 the ram clears the coal from plate 7 and compresses it into the space between two plates 9. The coal is carried by grate 3 over the open-topped channels 8 supplied with air through ducts 8a each of which is controlled independently by means not shown. The carbonized mass is finally ejected into a hopper 5. The ram 10 may have a projecting top plate 10a and side plates 10b. Alternatively these plates may be omitted or the plates 9 may have hinged parts which are swung over the coal on the grate. The pressure exerted by the ram is generally between 10 and 100 1b. per sq. inch and the speed of travel of the coal is 50 to 100 feet per hour which gives a heating time of 10 to 15 minutes. In a modification a vertically reciprocating ram is used. A small quantity of an oily, pitch-like or bituminous material may be mixed with the coal prior to the feeding of the latter on to the grate 3.

Title: Process for obtaining alumina in the manufacture of portland cement
Inventor: THILO ERICH
IPC: C04B7/02
Filed: 1956-03-14
Abstract: Sodium aluminate, from which alumina can be recovered conventionally, is obtained in the manufacture of Portland cement by proportioning the starting materials so that the content of Al2O3, CaO and SiO2 are within the range of primary crystallization of calcium disilicate as defined by a phase diagram (not illustrated) and after calcination separating the calcine into a finer and a coarser portion, the latter of which is leached with sodium carbonate solution to form sodium aluminate solution and a residue which is mixed with the finer portion; the mixture is calcined to form Portland cement, if desired after addition of clay.  Suitable starting materials are clay and other materials containing alumina, and fluxes such as lime, coke, and gypsum.  In the examples, there are employed (1) lime and clay only and (2) anhydrite, aluminium sulphate, clay, coke and sand; in each case a further quantity of clay is added before the second calcination.  Lime may be added later, also. The first calcination may be performed, e.g. in a rotary furnace, and in the examples temperatures of 1250-1280 DEG  C. and 1300-1350 DEG  C. are used. After calcination the mixture may be annealed at 100-150 DEG  C. lower than the temperature at which sintering begins. On cooling, the clinkers disintegrate and are separated, e.g. by sieving or air classification, into finer and coarser portions, preferably in the ratio 1 : 3; the fine portion may have a particle size below 25m . If desired the coarse material may be crushed before leaching.ALSO:In the manufacture of Portland cement sodium aluminate is obtained by proportioning the starting materials so that the content of Al2O3, CaO and SiO2 are within the range of primary crystallisation of calcium disilicate as defined by a phase diagram (not illustrated) and after calcination separating the calcine into a finer and a coarser portion, the latter of which is leached with sodium carbonate solution to form sodium aluminate solution and a residue which is mixed with the finer portion; the mixture is calcined to form Portland cement, if desired after addition of clay.
