Title: Reducing internal pressures of sealed containers
IPC: B65B55/02
Filed: 1973-05-18
Abstract: 1427748 Reducing pressures within sealed containers; endless conveyers SWISS ALUMINIUM Ltd 18 May 1973 [19 May 1972] 23822/73 Headings B8C and B8A A method of reducing the internal pressure of a container 12 filled with contents such as cream and of the kind comprising a lid 14 which is hermetically-sealed to a body 16 which is formed with an inwardly-domed base 18 of resilient, but plastically deformable material, comprises the steps of partially encasing the container with one or more, rigid members in such a manner that at least the lid is covered, the or each of the rigid members lying substantially directly against the outer surface of the container, then heating the container so that the pressure acting therein increases to such an extent that the base of the container is caused to deform plastically by flexing outwardly, thereby increasing the internal volume of the container, and finally allowing the container to cool to ambient atmospheric temperature. The container base 18, which is preferably integrally formed with the body 12, is made, e.g. of relatively thick aluminium foil or, of a semi-hard plastics material. As shown, filled containers are fed successively from a lidsealing machine 26 into corresponding recesses 36 in blocks 34 which form the individual links 32 of an endless conveyer 24 each recess 36 having a peripheral groove 38 to receive the rim 20 of a container and the base of the block 34 being adapted to limit the outward movement of the container base 18 and having an exhaust opening 44. A flap 50, pivoted at 48 to each block 34, is moved downwardly against the bias of a coil spring 54 by spring-loaded rollers 66 to contact and completely cover the lid of the container as the respective block passes through a heating chamber 30. While being conveyed through the heating chamber 30, which has rubber end-curtains 68, 70, the containers are heated to a temperature of over 50‹ C. to deform the container bases 18 outwardly the bases 42 of the blocks 34 limiting the outward deformation of the bases 18 which assume substantially planar form. A single link 32 could be constructed to carry several containers 12 side-by-side. Due to the reduced pressure within the containers the lid 14 may flex inwardly slightly. In a modification, Fig. 4, not shown, each link comprises a base-plate (42) which is connected to a separate block (34) by adjustable distance pieces which each comprise sets of individually removable rings (56) and an associated bolt (58).

Title: Improvements in or relating to presses for making briquettes
IPC: B30B11/20
Filed: 1926-09-27
Abstract: 265,879. Apfelbeck, H. Sept. 27, 1926. Rolling-machines. - In briquetting-presses of the type in which material is compressed within a groove in a ring by an eccentrically-disposed disc, the ring is formed in two sections having the radial joint off-set from the compression zone. As shown in Figs. 1 and 2, the ring comprises sections 9, 10 with twin portions 20, 21 interengaging by a shoulder 7 forming the base of the compression groove 2. The sections are pressed together at the compression zone by flanged rollers 1, 16 which may be adjustable for wear and are separated by a wedge-shaped collar 18 on a ring 17. A scraper 14 detaches the moulded material which passes to a discharge shoot 15. To prevent accumulation of material in front of the compressing disc 3, a preliminary pressure is applied by a roll 5 located adjacent to the hopper 4. Fig. 4 shows a modification in which the rim portions 22, 23 of the ring sections 12, 13 are recessed to embrace an intermediate ring 11, the joints 24 being off-set from the compression groove 2. The ring may be disposed vertically or horizontally.

Title: Manufacture of derivatives of phenoxy-acetic acid
Inventor: HARTLEY GILBERT SPENCER
IPC: C07C51/487
Filed: 1949-09-19
Abstract: Water-soluble salts of a crude chloro-phenoxy-acetic acid or of a crude chloro-methyl-phenoxy-acetic acid containing odorous chlorinated phenols or cresols are purified by treating an alkaline, neutral or slightly acidic solution of the crude salt with sufficient of a water-soluble permanganate to remove the odour while leaving the salt of the phenoxy-acetic acid substantially unaffected. Preferably, before the permanganate treatment, the greater part of the odorous compound is extracted from a slightly acidified solution with a suitable water-immiscible solvent, e.g. trichlorethylene.  The term "slightly acid" refers to aqueous solutions in which the pH is not below 5.5.  Following the permanganate treatment, which is normally effected at room temperature, the precipitate of manganese dioxide formed may be removed by filtration, sedimentation or by centrifuging.  Alternatively, the purified phenoxy-acetic acids may be precipitated as such, e.g. with sulphuric or hydrochloric acid, there being added a suitable reducing agent, e.g. sodium sulphite or ferrous sulphate, to dissolve the manganese dioxide.  The precipitated phenoxy acetic acid may then be dissolved in alkali or subjected to further chemical processing.  Examples describe the purification of aqueous solutions of sodium 2-methyl-4-chloro-phenoxy-acetic acid (recovered as pure free acid), sodium chloro-cresoxyacetate obtained by reacting sodium-o-cresylate with sodium monochlor-acetate, and sodium 2 : 4-dichlorophenoxy-acetic acid which is recovered as a solution of the pure acid with dimethylamine in water.  2 : 4 : 5-Trichloro-phenoxy-acetic acid is also mentioned.  Specification 592,827 is referred to.

Title: Manufacture of finely subdivided pigment dyes
IPC: C09B63/00
Filed: 1925-10-01
Abstract: The fine subdivision of organic or inorganic dyes or pigments in aqueous suspension is retained on drying by intimately mixing with a resin or a solid fatty acid, for example by mixing an alkaline or other solution of the resin or fatty acid with the colour suspension and precipitating by acid or other precipitant, or alternatively by fusing the materials together or by grinding them in a colloid mill. The preparations may be used as such or the admixed body may be eliminated before use by means of solvents without destroying the subdivision.  In examples a 20 per cent aqueous paste of a dyestuff, such as that obtained by coupling diazotized m-nitro-p-toluidine with acetoacetic acid anilide, is well stirred with an alkaline solution of a fatty acid, colophony, copal or an alkali-soluble artificial resin obtained, for example, by condensation of an aldehyde with a phenol or carboxylic acid, and the resulting mixture is acidified with hydrochloric acid, filtered, washed and dried; and aqueous paste of the above dyestuff is well stirred with an alcoholic or other solution of colophony, shellac, artificial resin, fatty acid or the like and the precipitation assisted by salting out; the same dyestuff is fused with colophony.
