Abstract: 1,265,788. Oxazoiinylamino compounds. E. I. DU PONT DE NEMOURS & CO. 1 April, 1970 [24 March, 1970], No. 14344/70. Heading C2C. The invention comprises compounds of formula and their acid addition salts, wherein R, R<SP>1</SP> are each H, Cl or C 1-3  alkyl, or R-R<SP>1</SP> form a fused ring (when the oxazolinylamino group is attached to either ring in the bicyclic system), Q is 0 or S, m is 1 or 2, and A, X, D, Z are each H or C 1-4  alkyl but total less than 9 C atoms. These compounds are prepared by reacting together, in an inert solvent, an aminofuran or aminothiophene with a C1CA(X)CD(Z)NCO to give the corresponding 3-(2-chloroethylureido)- furan or -thiophene, refluxing the latter with water to give the HCl-salt of the desired base, and obtaining the latter by adding NH 4 OH. Alternatively (e.g.) 3 - chlorocarbonyl - 2,5 - dimethylfuran is reacted with NaN 3  to give the corresponding azide, which is heated in toluene to give 3-isocyanato-2,5-dimethylfuran and this is reacted with 2-chloroethylamine to give the corresponding ureide which is converted to the desired product as above. Pharmaceutical and veterinary compositions for administration orally, parenterally, or by means of vapour or spray, comprise compounds of the above formula, which have antihypertensive and C.N.S. depressant activity.

Form mamide may be decomposed at 80-100 mm. Hg and 400-450‹C., cooled to 25‹C., and scrubbed with H 2 SO 4 . The gases may be compressed at 150-200‹C. to give a gas containing HCN and 15-25 vol. per cent steam. A gaseous stabilizer, e.g. HCI, may be injected downstream of the compressor. The condenser may be made of Cr-Ni steel or carbon. 3-5 vol. per cent of the aqueous HCN may be recycled 40-120 times per hour, and may be filtered in the circuit.

When the ester solvent forms an azeotrope with the isopropyl alcohol the azeotrope must have a lower boiling point than the ester solvent and when the ester does not form an azeotrope with isopropyl alcohol the ester must have a higher boiling point than isopropyl alcohol. The process is carried out in the absence of heavy metal ions. There may be formed propylene glycol and propylene glycol ester in addition to the propylene oxide. The preferred ester solvent is n-propyl acetate and the preferred acid is acetic acid.

Abstract: 1346059 Casting gypsum box-like units TSG INTERNATIONAL Inc 26 Oct 1971 [17 Nov 1970] 54650/70 Heading B5A [Also in Divisions E1-E2] A unit is cast from gypsum or a gypsum mixture between a core and an external mould, the external mould being removed when the gypsum is self-supporting, and the core being removed after a further time interval that is greater than the time between casting and external mould removal. The core is formed from or coated with a material having a higher coefficient of expansion than the interior surfaces of the external mould. The Cast Unit.-Rectangular packing cases, prefabricated tunnel or culvert sections, or prefabricated rooms are cast, having at least one open side. The rooms are fitted side-by-side and in layers as described in Specification 985,338. As described for casting a room, the walls 2-5 (Fig. 1) include strengthening ribs 7, door and window spaces 9, 10, and the corners are reinforced with steel angles. The floor is ribbed and surrounded by a steel frame (16) (Fig. 5, not reproduced), and the roof includes strengthening diagonals 11 having a hollow core and reinforcing rods. Mould and Core.-The mould comprises four walls 21 (Fig. 6c) and a top 23 movable by hydraulic rams. The walls are made from grillages of steel beams, metal plates and formers for the ribs, door, windows, &c. The core 19 is movable by rams 20 and comprises side walls 31 (Fig. 8), a top 32 and bottom 33 that are cast separately from super-gypsum (high strength) and water, joined by casting on corner junctions, and incorporate steel mesh 34. Gunite (dry cement and sand) is sprayed through a base hole 35 to form a layer and ribs 36; base recesses 37 receive air lift pads. The core is coated with a sheeting or spray of polyethylene or PTFE. Material.-The material for the unit comprises gypsum or gypsum and a cementitious material such as portland or aluminous cement, and includes sand, plasticisers, wetting agents, foaming agents and fibrous reinforcement such as sisal, glass fibre or polypropylene. Several examples are described. Method.-As described for casting a room, the core 19 (Fig. 6c) is positioned above a bed 17, and the reinforcements positioned before moving together the side walls 21. Gypsum and water are cast through a movable pipe until level with the top of core 19. The mould top 23 is lowered, and a stronger gypsum mix fed through an aperture in the top to form the roof. When the room side walls are self-supporting, the mould top 23 and walls of the mould 21 are removed ; the core 19 is lowered when the room roof is self-supporting. The room is lifted on to a further mould, and more gypsum and water cast through the room door to form the floor, within the steel frame (16) (Fig. 5). Internal fittings are applied. In an alternative embodiment, one wall of the mould is pivoted after casting (see Fig. 7, not reproduced), and the core moved horizontally while still supporting the room, a new core being then placed in the mould.
