Abstract: 1,130,186. Oxymethylene polymer-glass fibre compositions. CELANESE CORP. 18 May, 1966 [24 May, 1965], No. 22016/66. Heading C3P. A composition comprises (1) an oxymethylene polymer, (2) glass fibre, up to the weight of the polymer, and (3) 0À001 to 0À1% of the polymer of a hydrohalide acid or of a compound which decomposes to yield a hydrohalide acid when the composition is subjected to an elevated temperature, if necessary in the presence of traces of water. The polymer may contain a minor proportion of groups containing adjacent carbon atoms, e.g. derived from ethylene oxide or dioxolane, the polymer used in the examples containing 2 mole per cent of oxyethylene units. The preferred method of forming the composition comprises blending the hydrohalide-yielding compound with the polymer and heating the mixture to the melting-point of the polymer before incorporating the glass fibre. The exemplified components (3) are (1) HCl, (2), (3), (4) AlCl 3 , (5) AlBr 3 , (6), (7) chloroacetic acid, (8) NH 4 Cl, (9) polyvinyl chloride, (10) dihexylamine.HCl, (11) ethylamine.HCl, (12) undecylamine.HBr, (13) trioctylamine.HCl, (14) aniline- HCl, (15) 13-methylphenylamine.HCl, (16) cyclohexylamine.HCl, (17) naphthylamine.HBr, (18) pyridine.HCl, (19) piperidine.HCl, (20) TiCl 4 , (21) PCl 5 , (22) chlorosulphonated polyethylene, (23) chlorinated polyethylene, (24) chlorinated hydrocarbon wax, and (25) chloroisoprene rubber.

Title: Method of and detector for detecting an earth fault in a poly-phase electrical transmission system
IPC: G01R27/18
Filed: 1958-07-09
Abstract: 897,241. Protective arrangements. DOTZENRATH, W. July 9, 1958 [July 9, 1957], No. 22075/58. Class 38 (5). [Also in Group XXXVI] A polyphase A.C. transmission system is tested for earth faults by measuring the summation currents of the individual line or cable sections by means of a current transformer and determining the phase relationship of the transformer output with a reference. The Specification explains that where a fault exists on one phase T (Fig. 1) of a polyphase system capacitive currents leaving the phases RS return by the earth point in phase T. Thus a resultant capacitive current JCo (Fig. 2) flows in the system. Accordingly in the system shown in Fig. 6, where an earth fault exists in phase T on branch IV a current transformer is placed in turn round each of cables II to 15 in branch I. Cable II which connects ultimately to the fault shows an appreciably higher net current than cable 12 to 15. This current is in addition phase reversed with respect to that in cables 12 to 15. Determination of the differing current directions indicates that II leads to the earth fault. At distribution point II it is similarly indicated that cable II4 leads to the earth fault. A similar test indicates cable III, at distribution point III and III3 at distribution point IV. At distribution point V no cable can be found having a high net current indicating that these cables are beyond the earth point. The current in each cable may be measured by ring-type transformers which may be permanently mounted on the cable or may be constructed as shown in Fig. 4, when a part 3 of the yoke E is pivoted by a lever 4 operated through a handle 1. Fig. 5 shows a circuit in which the phase and magnitude of the transformer current is measured. Transformer output is applied by divider 5 to amplifier 7, a current proportional to the cathode current of which is fed through a phase adjuster 10 to amplifier 9, transformer 13 and ring modulator circuit 14 also fed with a reference from low-voltage transformer 12. Centre zero meter 16 connected between the centre tap of transformer 13 and that supplying the reference to the ring modulator indicates a change in phase of the current transformer output. The phase adjuster 10 is so set that maximum deflection of the meter on one cable is achieved when a change in direction of the current is immediately indicated. A transformer may be provided permanently for each cable. On the response of an earth signalling relay a rotary selector is started which successively explores the various transformers. A polarized relay connected in the meter circuit responds on reversal of the current direction and switches on an indicating device through an auxiliary relay. This device may comprise a series of bulbs, one of which is lit up when a fault is present.

Title: Concentration of solutions

Filed: 1976-06-02
Abstract: 1525078 Freeze crystallisation of solutions K ZONDEK 2 June 1976 22704/76 Heading B1G A process for concentrating solutions comprises cooling in at least two stages a solution, containing a crystallisable solvent and/or a crystallisable or amorphous solution, by injecting and expanding therein a low boiling, high vapour pressure liquid refrigerant. A first stage crop of substantially pure crystals which form are separated from the mother liquor, and the mother liquor is then further cooled and crystallised in further stages. Any crystals from the further stages are returned to the first or preceeding stages. The mother liquor from the final stage is stripped of refrigerant and recovered as a concentrate. The process is particularly applicable to the freeze concentration of juices, coffee or tea extracts and beers wherein concentration is achieved by removal of ice crystals in a pure form so that essential ingredients of the solution being concentrated are not lost. Suitable apparatus, as shown in Fig. 1, comprises a first contact vessel R 1 , to which is pumped a fish feed of juice FJ, connected to a crystal separating centrifuge C,. The temperature within the contact vessel R 1  is continuously reduced by the direct injection of refrigerant through valves CV 1 . The mother liquor from the centrifuge is continuously returned to vessel R, and the crystals collected are washed. A portion of the first stage concentrated mother liquor is pumped into a second stage contact vessel R 1  which operates in a manner similar to that of the first stage, but is cooled to a lower temperature. Refrigerant is stripped from the concentrated mother liquor from the second stage in vacuum column 4 to yield the final concentrate.

Abstract: 1,062,485. Dehydrated food stuffs. J. CORDING. June 3, 1964 [June 3, 1963], No. 23082/64. Headings A2B, A2D and A2Q. In a process and apparatus, Figs 1 and 2, for producing deyhdrated pieces of food, e.g. fruits or vegetables, which can be rapidly rehydrated, partially dehydrated pieces of food are fed, by gravity, through an inlet opening 3 and an air-lock valve 4, on to a conveyer 2 in a pressure chamber 1, and are heated therein, as by live steam or radiant heat, to raise their temperature to at least 100‹C. The chamber 1 has an outlet passage leading into the downwardly directed, smaller chamber of a puffing gun 7, whose muzzle is closed by a gas-tight closure 8, which can be opened quickly. The conveyer 2 conveys the heated pieces of food into the gun 7. The pressure, in the chamber 1 and the gun, is raised to a desired value by introducing, into the chamber 1, air, carbon dioxide or nitrogen, or a mixture of any of these gases, preferably of low oxygen content. When the gun is substantially filled with pieces of food, the passage between it and the chamber 1 is closed by an air-tight closure 6, and the closure 8 is then quickly opened to discharge the pieces into the normal atmosphere, so that they become puffed and porous. In order to maintain the pressure in the chamber 1, it is essential that one of the closures 6 or 8 should be closed before the other is opened. The conveyer 2 may be a vibrating conveyer, e.g. comprising a stainless steel platen. Alternatively, this conveyer may be an endless belt, e.g. of stainles steel. There may be a plurality of guns 7, Fig. 2, and the pieces of food may be directed into different guns by baffles or helical conveyers 9. Each gun may be heated externally, by a steam jacket or an electric heater 10. The discharged pieces of food are finally dried to a stable moisture content.

The ethers so obtained, preferably after being dehydrated and purified, are employed dissolved in a solvent as lacquers and coating compositions; The' expression similar solvents to acetone includes dioxane, ethyl acetate, butyl acetate diacetone, mesityl oxide and chloroform. A coating of the benzyl ethers of dextran may be applied by, brushing or roller coating, but preferably by spraying, and is stated to be substantially non-inflammable, and to possess sufficient flexibility not to require the addition of plasticisers. Numerous examples are given employing varying amounts of dextran, benzyl halides, alkali, and water under varying conditions of temperature and pressure. The products are purified by steam distillation, followed by maceration in water and drying.Specifications 517,397 and 517,398 are referred to.
