Abstract: 1,154,144. Sulphur-containing copolymers. SOC. NATIONALE DES PETROLES D' AQUITAINE. 8 June, 1966 [9 June, 1965], No. 25474/66. Heading C3P. A substantially linear, amorphous, unsaturated copolymer comprising monomeric units of one or more mono-olefines and units obtained from an unsaturated trithiane ring compound having three sulphur and three carbon atoms in its ring, with at least two alkylidene radicals linked to the ring, are made by polymerizing a mixture of the monomers in the presence of a Ziegler-type catalyst. The term "alkylidene radical" includes the methylidene radical. Specified trithianes are 2,4,6-triethylidene- 1 3,5-trithiane and 2,4,6-trimethylene- 1,3,5-trithiane. The mono-olefines may be ethylene and/or propylene. The catalyst may be preformed and if desired, "aged", or formed in situ. The copolymerization may be carried out batchwise or continuously, in bulk or in a hydrocarbon or halogenated hydrocarbon solvent or diluent The exemplified catalyst is VoCl 3  and (C 2 H 5 ) 2  AlCl. The copolymer is recovered by killing the catalyst in a conventional manner e.g. with water, steam distilling the reaction mixture in vacuo at a temperature of from 30 to 60 C., and finally drying the copolymer in vacuo, at a temperature of about 40 C. The copolymers may be vulcanized with sulphur or a free - radical producing agent. The copolymers may be used in the manufacture of electric cables, conveyer belts, tubes, and pneumatic tyres.

Filed: 1926-10-13
Abstract: 276,522. Synthetic Ammonia & Nitrates, Ltd., Slade, R. E., and Harrison, C. F. R. Oct. 13, 1926. Coking processes.-Carbonaceous materials are treated with superheated steam, the organic compounds separated from the steam at relatively high temperature and the steam re-circulated through the material. The powdered material preheated to above the temperature of condensation of steam is showered through steam entering at a temperature of 450‹ C., preferably in a horizontal rotary retort, the temperature of the steam at the exit end being 300‹ C., very little gas being evolved (1 to 2 per cent by weight of the fuel) and 10 to 15 per cent of volatile matter being left in the semi-coke. The mixed steam and distillates are reduced to 150‹ C. by injecting water which is vaporized and the gases are then scrubbed with oil to remove the condensible, constituents, the residual steam being heated and returned for use in the retort. The permanent gases evolved are periodically removed from the circuit. Increased' or reduced pressure may be employed and catalysts such as iron oxide with or without alkali may be added to the charge.

Title: Improvements in or relating to germicidal products or articles
IPC: A47J36/22
Filed: 1932-09-15
Abstract: Germicidal products or articles consisting of an oligodynamic metal, such as silver or copper, deposited on a carrier or on an instrument or vessel, are activated or rendered more rapid in their sterilizing action by corrosion of the metal surface by chemical or other means such as by insertion in an electrolytic circuit as the anode.  The metallized carriers may be in the form of shaped or shapeless masses or powder formed of ceramic material, bole, or silica gel, coated or impregnated with silver or copper as by moistening with a solution of a silver salt and treating with alkali and formaldehyde; or by coating or impregnating with a silver salt solution, drying and heating; or by heating with ammoniacal copper sulphate solution and hydrazine hydrate; or instruments, such as forceps, or vessels or other objects of base metal may be silver plated galvanically or otherwise.  For activation the metallized carrier may be treated with hydrogen peroxide solution and either filtered and dried or evaporated to dryness; or may be treated with a hypochlorite solution, or with wet or dry chlorine gas followed by exposure to a current of air; or may be mixed with a dry reagent, such as hydrogen-peroxide-urea or a per salt or a solid hypochlorite, so that corrosion takes place on adding water to the mixture; or may be electrically treated as referred to above.  The products may be used for sterilization of water, fruit juices, milk or medicinal solutions for injection, or may serve as ingredients of pharmaceutical or cosmetic products such as internally administered disinfectants, mouth washes and gargles, dentifrices, and ointments.  Corrosion by igniting or calcining the metallized carriers is excluded.  Reference has been directed by the Comptroller to Specifications 221,000, 282,112, 335,215, [all in Class 1 (i)], 350,451, [Group III], and 355,086.

Patent GB-816299-A (GB)
Title: A process for the production of 1-(ª‰-hydroxypropyl)-theobromine
Filed: 1956-08-23
Abstract: In a process for the production of 1-(b -hydroxy - propyl) - theobromine, 1 - allyl-theobromine is reacted with a substance which facilitates the adding-on of water to the 1-allyl theobromine and, either simultaneously or subsequently, with water.  It is preferred to facilitate the adding-on by using sulphuric acid of 50-100 per cent by weight concentration at 50-100 DEG  C., borontrifluoride at above 100 DEG  C., or phosphoric acid of 50-100 per cent by weight concentration at 100-160 DEG  C.  In an example 1-allyl theobromine is dissolved in concentrated (96-98 per cent) sulphuric acid, without cooling, allowed to cool to room temperature, reheated to 70-80 DEG C., stirred into water and refluxed.  The resulting solution is neutralized with sodium hydroxide solution evaporated to dryness and recrystallized from isopropanol to give 1-(b -hydroxy-propyl) theobromine.  In a second example, the temperature during the solution of 1-allyltheobromine in sulphuric acid is kept below 30 DEG C., thereafter raised to 50-65 DEG  C. and finally heated to 75-80 DEG  C. In a third example, boron trifluoride dihydrate is used in place of sulphuric acid, and the mixture heated to 120 DEG  C., before refluxing with water.

Title: Improvements in the depolymerisation of mono-olefine polymers
IPC: C07C4/22
Filed: 1938-09-05
Abstract: 518,558. Depolymerizing olefine polymers. I. G. FARBENINDUSTRIE AKT.-GES. Sept. 5, 1938, No. 25930. Convention date, Sept. 7, 1937. [Class 2 (iii)] The catalytic depolymerization of polymers of low boiling mono-olefines is effected in the presence of appreciable amounts, usually more than 20 per cent. by volume of the vaporized polymers, of steam. The life of the catalyst is thereby prolonged. Temperatures are usually 200-400‹ C., preferably 230-330‹ C. and pressure atmospheric but it may be reduced or increased. Surface-acting catalysts such as bleaching earths which may be pre-treated with acids, e.g., hydrofluoric or hydrochloric acid, are specified. Polymers - boiling above 170‹ C. of olefines boiling below 100‹ C., e.g., trimer, tetramer and higher polymers of isobutene or isohexene, and higher polymers of propene, pentenes, hexenes, and heptenes are suitable initial materials. In an example, tri-isobutene is vaporized and mixed with steam to form a mixture containing 42 per cent. of steam ; this is led at 230‹ C. over " tonsil" to produce isobutene and diisobutene. The Specification as open to inspection under Sect. 91 also states that the amount of steam is usually not more than 80 per cent. and is. preferably from 40 to 60 per cent. In addition, it includes two further examples which describe the passage of a mixture of (1) di-isoheptene vapour and steam over "Frankonit H" to give isoheptene, and (2) tetra-isobutene and steam over "Frankonit H" to yield a mixture of isobutene, di-isobutene and. tri-isobutene. This subject-matter does not appear in the Specification as accepted.

[Class 38(v)] [Also in Group XXXIX] In an electromagnetic relay, a hairpinshaped member 4, the shanks of which form selecting fingers, is associated with each pair of spring contact sets. The members 4 are supported by studs 3 on a frame 2: fixed to the armature 1 and the ends of the shanks extend into holes in a holding bar 5 and embrace studs 6 between the holes, as shown. If the armature is attracted with the fingers in the position shown, the bar 5 moves upwards into cutouts 10 in devices 9, none of the contacts being actuated.
