Title: Process for the production of heavy water
IPC: C01B5/02
Filed: 1958-11-27
Abstract: In the production of water enriched in heavy water, the water condensed from the products obtained by the gasification of coal (or other solid material containing more than 50% carbon) at elevated temperature is used as the water supply to a known heavy water enriching process, since it is found that this condensed water is already enriched in D.  Processes of heavy water enrichment, are distillation, electrolysis, electrolysis combined with steam/H2 exchange, or dual temperature exchange, e.g. water/water, steam/H2, and water/H2S.  Pulverized and/or lump, hard or soft coal, coke, or peat, may be gasified at atmospheric, or elevated, e.g. above 5 kg./sq. cm., pressure and 800 DEG -1,300 DEG C. in the presence of O2, or air, and, preferably, of steam.

Abstract: Polyester fibres or fabrics are treated in an aqueous medium at a temperature not exceeding 75 DEG  C. with a brightening agent which is free from water-solubilizing groups and contains at least one heterocyclic ring fused on to a benzene ring, and are then subjected to a dry heat treatment at a temperature above 100 DEG  C. Specified brightening agents include the compound <FORM:0827992/IV(c)/1> and a : b -di-[N-methyl-benzimidazolyl-(2)]-ethylene.  The compounds may be dispersed with the aid of ethylene oxide addition products with alkyl phenols or alkyl-aryl sulphonates or other suitable agents, or may be dissolved in a watermiscible organic solvent and then added to water. The impregnation may be effected at room temperature and the fibres may then be dried at a moderate temperature (60-100 DEG  C.) and heated to between 120 DEG  and 225 DEG  C., in a drying chamber, by ironing, or with dry superheated steam. In Example 2 the treatment bath also includes ammonia.

Title: Method of purifying crotyl alcohol
Inventor: KUDO SHIRO
IPC: C07C33/02
Filed: 1964-09-29
Abstract: Crotyl alcohol and butanol are separated from butanol-containing crotyl alcohol by a distillation process wherein the butanol-containing crotyl alcohol is fed to an intermediate part of a distillation zone, water is introduced into the zone at a higher level than the alcohol mixture and the concentration of the water in the internal reflux below the water feed point is maintained at more than 70% mol, whereby butanol and water are obtained as an overhead distillate and aqueous crotyl alcohol is withdrawn from the bottom of the distillation zone. Anhydrous crotyl alcohol can be obtained by subjecting the aqueous mixture to an azetropic distillation step using, e.g., benzene. The process is illustrated by reference to drawings (not shown).

Title: High speed smelting in vertical furnace
IPC: C21B13/00
Filed: 1964-10-02
Abstract: Ores of iron or other metals are charged into a shaft furnace together with dense briquettes of coal which has sufficient volatile matter to produce hydrogen in the furnace and which on high temperature distillation forms dense rigid coke without cracking or binding.  After the briquettes have been initially charged the amount of oxygen per ton of metal supplied by the blast is reduced to less than the amount contained in 1000 m3 of air under normal conditions. The charging rate of carbonaceous material per ton of metal produced may also be reduced as compared with that conventionally used; the blast may consist of oxygen-enriched air, or of substantially pure oxygen, when the furnace top gas may be subsequently used in chemical synthesis.

Title: Isomerisation of butene-1 to butene-2
Inventor: TURNER LEONARD
IPC: C07C5/25
Filed: 1965-09-22
Abstract: Butene-1 is isomerized to butene-2 in the presence of isobutylene by passage over a supported nickel catalyst, the nickel being present under operating conditions in major proportion as elemental nickel, and the catalyst having previously been modified by treatment with one or more of (a) elemental sulphur, (b) an organic sulphur compound, (c) H2S or (d) CS2, the treatment being so conducted as to give a sulphur : nickel atomic ratio in the treated catalyst in the range 0.01-0.4.  Suitable compounds (b) are thiophenes, thiacycloalkanes, dialkyl monosulphides, mercaptans, and di-alkyl disulphides.  The catalyst support may be sepiolite, kieselguhr or chalk.  The isomerization is preferably carried out in the presence of hydrogen, and any acetylenes and/or dienes in the feed are then selectively hydrogenated to the corresponding mono-olefins.  In an Example, a C4 stream containing inter alia butene-1, butene-2, isobutylene and butadiene was isomerized as above, the butene-1 being converted to butene-2, the isobutylene remaining unchanged, and the butadiene being selectively hydrogenated to n-butene.

This reduces "cross-view" in multipair transmissions. Preferably the chrominance bands do not overlap to a significant extent. Further pairs of programmes may be transmitted on further cable pairs in a similar manner but with the respective luminance carriers separated by line and/or frame frequency offsets (e.g. 1/3 line plus 1/3 frame) from the 7 MHz difference illustrated. The pilot frequency in one pair is used to synchronize demodulation of the corresponding programme in the other pair as detailed in the Specification 1,474,633.

Abstract: 411,736. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hathaway, C. M. ; 40, Irving Road, Scotia, New York, U.S.A.) Oct. 16, 1933, No. 28613. Convention date, Oct. 15, 1932. [Class 38 (v).] A thermal switch suitable for controlling an electric iron or similar apparatus, comprises a movable contact 14 mounted on a spring arm 16 connected to a strip 17 having a curved transverse section, and mounted with its concave surface upwards. The fixed contact 15 is carried by a spring 18 fixed by rivets 19 to a rigid arm 20, a stop 21 limiting the movement of the spring 18. A bimetal strip 11 is mounted on an adjustable post 12 on the base 10 and its free end 13 is adjacent the contact 14. On a rise of temperature the bimetal strip bends and moves contact 14 upwards causing the curved strip 17 to bend. After a while the strip 17 buckles and its resistance to bending is suddenly decreased, and the contacts 14, 15 engage rapidly. The reverse action occurs on cooling, the strip 18 having a follow up action to prevent a slow separation of the contacts.

In apparatus for digitally determining a measured value as in the parent Specification 1,076,266, a binary counter comprising trigger circuits 115, 116, 117 (Fig. 1) primed by a measuring command on conductor 100 starts counting clock pulses from one unit below its zero position on receipt of either a reference pulse enabling gate 113 via trigger circuit A or a measuring pulse enabling gate 114 via trigger circuit B depending on which pulse occurs first. The count is then stopped on receipt of either the next measuring pulse (which sets trigger circuit B to block gate 113) or a reference pulse (which sets trigger A to block gate 114) respectively. In the first case the count represents one unit less than the measured value and a supplementary counting pulse is supplied via gate 112 enabled when trigger circuit B sets trigger circuit C via gate 111. In the second case the count represents one unit less than the complement of the required value (since the maximum count possible represents the time interval between two pulses on the same conductor 101 or 102) and either the trigger circuits 115, 116 ... are switched to their complementary state before read out by a pulse via AND gate 110 or the reset sides of the circuits are read out (Fig. 4, not shown).
