Title: Stabilized polyalkylene oxides and process for preparing them
IPC: C08K5/132
Filed: 1965-04-12
Abstract: Polyalkylene oxides are stabilized by a mixture of the following compounds:  (a) 1 to 5% of a compound of Formula (I) <FORM:1102253/C3/1> in which R represents an alkyl group of 1 to 18 carbon atoms; (b) 0.1 to 2% by weight of bis-(4 - hydroxy - 3 - t - butyl - 6 - methyl - phenyl)-sulphide; and (c) 0.1 to 2% by weight of a compound of Formula (II) R1-Sn-R2, in which n is 1 to 4, R1 and R2 are alkyl radicals of 8 to 20 carbon atoms or a group of formula -(CH2)mCOOR3, in which m is 1 to 4, and R3\t is an alkyl group of 8 to 20 carbon atoms; each percentage being based on the weight of the polyalkylene oxide.  Suitable polyalkylene oxides are those obtained by polymerizing saturated alkylene oxides, halo-substituted epoxides, including epichlorohydrin, cycloaliphatic epoxides or epoxy ethers, including glycidyl ethers, or by copolymerizing saturated epoxides with unsaturated epoxides, e.g. glycidylacrylate. Typical examples of compounds of Formula (I) are 2,4,5-trihydroxyacetophenone, 2,4,5-trihydroxy caprophenone, and 2,4,5 - trihydroxy - phenyl - decyl - ketone. Typical examples of compounds of Formula (II) are di(dodecyl)sulphide, di(octadecyl) trisulphide, thiodipropionic acid octadecyl ether and tetrasulphide (diacetic acid octadecyl ether). The stabilizer may be added as a solid or in a solution. The stabilized polymers may be dissolved or caused to swell, and may be cross-linked.  Swelling agents or solvents include: dimethyl formamide, tetramethylene sulphone, dioxan, methanol, benzene, and chlorinated hydrocarbons.  Soots, fillers, dyes or pigments, extender oils or lubricants may also be added.  The example describes the stabilization of a methanolic solution of a propylene oxide-allylglycidyl ether copolymer, thiourea, silicic acid, zinc oxide, dipentamethylene thiuram tetrasulphide, 2-mercaptobenzothiazole and titanium dioxide with a mixture of 3% of 2,4,5 - trihydroxybutyrophenone, 0.5% of bis (4 - hydroxy - 3 - t - butyl - 6 - methyl - phenyl) sulphide and 0.5% of di (octadecyl) disulphide, the percentages being based on the weight of copolymer. The resulting copolymer was spun and the filaments cross-linked.

Abstract: 1,194,413. Coating apparatus. DUNLOP CO. Ltd. 2 April, 1968 [5 April, 1967], No. 15513/ 67. Heading B2L. Collapsible, e.g. textile, tubes are coated by being drawn over a supporting member which extends through two opposed holes in the walls of a reservoir containing coating material. As shown, the supporting member 1 comprises cylindrical supporting portions 2, 3 provided on a tubular mandrel 12 which terminates in a spatular portion 4. Member 1 is adjustably supported by a roller 8 located adjacent cylinder 2 and rollers 9 located adjacent cylinder 3. Cylinder 2 passes through opposed holes 11 in the walls of a reservoir 5 containing coating material such as a polyurethane composition or a rubber latex. Annular seals 6 surround the holes 11 to prevent seepage of the coating material. The end of a collapsed tube is opened and drawn around and along cylinder 2 until it passes completely through reservoir 5 and is then attached to traction means which draws the tube progressively through reservoir 5, through an oven 14 where the coating is dried or vulcanized and over cylinder 3, after which the tube is nipped between rollers 9 assumes elliptical form, the tube finally passing in flattened form over the spatular end 4 to a batch-up roller 13. In modifications cylinder 2 is tapered, or is provided at each end with a flange and the recess formed between the flanges contains a hollow inflatable sleeve, or is provided with end plates supporting a tube of plastics material, the end plates being adapted to be secured towards each other a supporting member for altering the diameter of cylinder 2.

Title: Improvements in or relating to brewing of beer
Inventor: HALL RONALD DAVID
IPC: C12M1/02
Filed: 1960-05-03
Abstract: <PICT:0979491/C6-C7/1> <PICT:0979491/C6-C7/2> In a continuous fermentation process involving fermentation of a fermentable liquid (brewers wort) by yeast, the liquid is caused to flow along an ascending path through a liquid-permeable plug of yeast which is substantially unobstructed over its cross-sectional area and yeast which rises in the liquid is caused or permitted to flocculate within the flow path without being re-circulated externally thereof whereby the yeast is retained within the flow path. A strain of yeast capable of spontaneous flocculation should be employed.  Wort from an inlet 25, Fig. 1, is fermented by a plug 32 of yeast in a fermenter 10 and fermented wort passes along an outlet pipe 26 to a collecting vessel 27.  The fermenter, which may be inclined, for example at an angle between 9 degrees and 45 degrees to the horizontal, arranged vertically, or in the form of a helix having 3 1/2 turns or zig-zags composed of 3 or 5 straight lengths, is temperature controlled by the flow of water or air through a jacket 15 or by tape containing a resistive heating element (not shown). The outlet line 26 for the fermented wort has a branch feeding a removable sampling vessel 31. The rate of fermentation may be automatically adjusted by valves 23 and 24 in response to a detection of the quantity of carbon dioxide from the fermenter tube. Gas, such as carbon dioxide gas released from the vessel 27, is admitted through a line 22 to the fermenter wherein the bubbles 35 produced (for examples 1 - 10 ml. size for a fermenter 1 inch in diameter) serve to release gas bubbles from the yeast cells or clumps, thereby aiding flocculation. Alternatively, these bubbles may be released by applying a vibrating member to the liquid or by establishing pressure vibrations of gas adjoining the liquid in the flow path at its upper or lower ends.  A substantial quantity of oxygen is admitted to the liquid when it is desired to establish aerobic fermentation promoting yeast growth; the yeast obtained may be removed continuously or periodically from either the upper or the lower end of the flow path. In a further embodiment, fermenter tubes 11. Fig. 2 and Fig. 3 (not shown), are arranged vertically in a circle and communicate with inlet and outlet chambers 43 and 44.  Individual tubes may be cut out by valves 40, 41, for cleaning and sterilizing with steam. Operational examples are given.

Apparatus for loading or unloading crates with bottles &c. includes endless conveyer belts having means to grip groups of bottles for release in a crate or on to a discharge conveyer. The embodiments shown are unloading but may be run in reverse for loading and in one, filled crates are forwarded by a conveyer 3 so that opened gripper elements on belts 5 engage the bottle necks. Each crate arrives on a support 16, 16a, one of a pair mounted on arms 18 pivoting at 19. The arms rotate so that the crate is lowered leaving the bottles hanging from the belts. The supports 16, 16a have rollers 20 mounted cantilever fashion which, as the support descends, pass between similarly mounted rollers 21. The crate is taken off the support by the latter and rolls on to a discharge conveyer 4. The bottle grippers are opened successively by means 11 to deposit them on a conveyer 3. The supports are locked resiliently in their upper and lower positions and are released by the crates. Conveyers and grippers.-The belts themselves may be of continuous gripper section, Fig. 2, or groups 5 separated by distances between crates may be secured to chains. Rails 13 may support the lower run. Individual grippers 5c may be used. The grippers may be opened by rotary means 10 to receive the bottle necks, be held closed by the rails 13, and re-opened by the member 11 which is of plough form with flanking rollers (Fig. 3 not shown) and also acts as a stripper with its under surface. The machine is adjustable for handling various sizes of article.
