Abstract: 1369539 Dispensing closures M B STULL 12 May 1972 [12 May 1971] 22542/72 Heading B8T A dispensing type closure for screw-threaded and non-screw-threaded squeeze bottles comprises a moulded one-piece plastics cap retained on a bottle neck but movable by twisting or pulling between a depressed sealing position and a raised dispensing position, the cap having one or more dispensing orifice and a spout in its top wall not projecting above the remainder of the top wall, wherein an annular bead on the cap engages the container neck at all times to prevent leakage of liquid past the exterior of the neck. In Fig. 1, the cap 54 is retained on the bottle neck 42 by a shoulder 48 on the neck 42 which engages with a bead 66 on the cap 54, and which seals against surface 50 of the neck. The cap 54 is moved from the sealing to the dispensing position by the co-operating screw-threads 44 and 56 on rotation of the cap 54. In the dispensing position, an inner sealing bead 74 on the cap 54 is disengaged from a sealing surface 52 of the neck and allows liquid to be discharged through an arcuate dispensing orifice 62 to a spout 60. Excess liquid is returned by drainback recess 72. The cap 54 is tapered, and the spout 60 falls within the described cylinder, so that normal automatic capping machines may be utilized. In Figs. 3 and 4 (not shown), four discharge orifices are provided in the top wall of the cap around the periphery of a circular drainback recess which has an upwardly convex projection at its centre. In Figs. 5 and 6 (not shown), the cap has a single discharge orifice and its drain back recess is only a small sector in plan. An arrow is indented into the top wall of the cap to indicate the discharge orifice. The cap is not screwthreaded, i.e. it is of push-pull type.  In Figs. 7, and 8 (not shown), the discharge openings 136 extend laterally of the cap, and the sealing plug 138 is supported by radial webs 140.  In Figs. 9 and 10 (not shown), the cap is similar to that of Fig. 1, but is of push-pull type. The drainback recess is semicircular in plan. In Figs. 11 and 12 (not shown), the rim of the cap is cut away on each side of the spout of a push-pull cap. In Figs. 13 and 14 (not shown), the tubular plug 68 of Fig. 1, is reduced to an annular conical bend on the top wall of the cap. In Figs 16, and 15 (not shown), the screwthreads on the bottle neck and cap are of undercut wedge-section, which permit the bottle to be closed by forcing the cap downwards and giving a final twist to it. In Figs. 17 and 18 (not shown), the tubular plug 68 of Fig. 1, has an outwardly projecting annular bead which engages a groove in the inner wall of the bottle neck to seal and retain the screw cap.

Abstract: The invention comprises compounds of the formula <FORM:0981827/C2/1> where R represents a hydrogen atom or a methyl group, R1 represents a hydrogen atom or an alkyl radical having 1 to 4 carbon atoms and R11 represents a hydrogen atom or a radical of an aliphatic, cycloaliphatic, aromatic- or heterocyclic carboxylic acid having from 1 to 10 carbon atoms, unsubstituted or substituted by halogen atoms, free or alkylated amino, nitro, hydroxy, alkyl, alkoxy or thioether groups, and the preparation thereof by the reduction of lumilysergic acid, 1-methyl-lumilysergic acid or a corresponding 8-ester-10-ether derivative thereof, to give lumilysergol, 1-methyl-lumilysergol or the appropriate 10-ether derivative; and, where necessary, esterifying to yield the corresponding acyl derivatives.  The carboxyl group is preferably protected prior to reduction by, for example, formation of an ester or a mixed anhydride.  The reduction is carried out with a reducing agent which is capable of reducing a carboxylic group into an alcohol group, e.g. lithium aluminium hydride, in a solvent stable towards the reducing agent, e.g. an ether.  It may be carried out at room temperature but is preferably completed by warming.  The 8-acyl derivative of the lumilysergol and 1-methyl-lumilysergol so produced may be made by reaction with an acylating agent e.g. the anhydride or chloride of the appropriate carboxylic or sulphonic acid, optionally in the presence of a tertiary amine.  Lumilysergic acid and 1-methyl-lumilysergic acid may be prepared by U.V. irradiation of the corresponding lysergic acid dissolved in a dilute mineral acid.  Methylation of the 1-nitrogen atom may be carried out before or after irradiation by reaction with a methyl halide in liquid ammonia in the presence of metallic potassium.  The 8 - ester - 10 - ether derivatives of lumilysergic or 1-methyl-lumilysergic acid may be prepared from the corresponding acids by simultaneous etherification and esterification by treatment of a solution thereof in the required alcohol with anhydrous hydrogen chloride.  Therapeutic compositions with oxytocic, anti-enterammic, adrenolytic, hypotensive, and sedative activity, which may be administered orally, intramuscularly, subcutaneously and intravenously and may take the form of tablets, powders, pills or liquids, comprise compounds of the general formula given above together with a therapeutically acceptable solid or liquid vehicle therefor.

Title: Improvements in or relating to silicas
IPC: C01B33/193
Filed: 1955-08-11
Abstract: <PICT:0800694/III/1> Finely divided silica is produced by treating the surface of an aqueous solution of an alkali metal silicate with an acid-reacting substance and drawing the treated surface into the body of the solution, and dispersing it therein, by means of a rotary stirrer 3 having arcuate blades 9, a fresh surface thereby being formed for treatment.  The reaction vessel may be provided with baffles 5.  The atmosphere above the silicate solution may be sprayed with a solution of the acid from a pipe 11 and the spray may strike the surface of the solution.  A conventional lawn soaker spray may be employed.  When using a solution of an acid gas or a readily volatile liquid acid, the solution may be sprayed at an elevated temperature, e.g. above 50 DEG  C., so as to saturate the atmosphere with the acid.  An acid gas may also be supplied as such to the atmosphere. Acidreacting substances specified are hydrochloric, sulphuric, nitric, sulphurous, phosphoric, hydrobromic and carbonic acid, aluminium chloride and sulphate, and ammonium chloride.  Sodium silicate of the formula Na2O(SiO2)x, where x is 2-4 is preferably employed, but sodium monosilicate and potassium silicates may also be employed.  The silicate solution may contain sodium chloride or sulphate and the aqueous acid calcium or aluminium chloride. One half of the silicate may be neutralized over a period of 100 minutes. Thereafter neutralization may be effected at a more rapid rate and by the use of other methods.  In the example a sodium silicate solution at a temperature of 149-152 DEG  F. was stirred by means of a turbo agitator rotating at 70 r.p.m. and was sprayed with 12.2 N hydrochloric acid at a temperature of 25 DEG  C. for a period of 329 minutes, after which time the resulting slurry had a pH of 7.  The slurry was then boiled for 1 hour giving a pH of 8.5, allowed to cool and further hydrochloric acid added, giving a pH of 8.2.  After decanting the mother liquor, the silica was treated with 0.225 per cent of a mixture of dimethyl dialkyl ammonium chlorides in aqueous solution, and the mother liquor again decanted.  The silica after drying has a surface area of 121 sq.m/gm.  Specification 745,822 is referred
