Title: Improvements in or relating to the preparation of stomach powders comprising one or both of the carbonates of magnesium and calcium and aluminium hydroxide
Inventor: GORE DAVID NEVILLE
IPC: A61K33/10
Filed: 1953-11-13
Abstract: An antacid preparation in the form of a finely divided stomach powder is prepared by mixing an aqueous solution of a carbonate e.g. sodium carbonate, with an aqueous solution of salts of aluminium and one or both of the metals magnesium and calcium, recovering the precipitate of the carbonates of the magnesium and/or calcium and aluminium hydroxide, and drying the precipitate at a temperature of up to 60 DEG C.  The precipitate preferably comprises 42 to 50 parts by weight calcium carbonate, 13 to 30 parts by weight magnesium carbonate and 17 to 26 parts by weight aluminium hydroxide, and is capable of being dried at higher temperatures than is normally possible without loss of any antacid buffering activity of the hydroxide.  The solutions are heated to about 70 DEG C. prior to mixing, and after mixing, the solution may be heated to and maintained at about 90 DEG C. for about 20 minutes to eliminate carbon dioxide from the reaction mixture and to convert the precipitate to a filterable form. Specifications 532,300 and 539,157, [both in Group III], are referred to.

Title: Process and apparatus for automatic rolling and packaging of products in strip form
IPC: B65B63/04
Filed: 1964-08-04
Abstract: 1,011,281. Packaging by rolling. COMPAGNIE DE SAINT-GOBAIN. August 4, 1964 [August 5, 1963], No. 31671/64. Heading B8C. As a sheet 10 (Fig. 1) is wrapped around the rolled strip 40, it tears from the main web 5 along a line of weakness 27, and is then secured about the roll by glue provided adjacent the line 27. In the apparatus described, the strip 1 is rolled up by two conveyers 3, 4 whilst blades 21 and glue guns 24 provide stationary web 10 with firstly a line of weakness 27, and then adjacent to that a line of glue. Movement of the trailing edge of the strip 1 past a switch 28 releases a brake 6 on the roll of wrapping material 5 and activates the feed rollers 9 and 12. The leading edge of the sheet 10 is caught in the last convolution of the roll 40, and wrapped around the roll by the conveyers 3, 4. Movement of the sheet 10 is measured by the roller 15 and a ratchet system 17, which after the sheet has gone round the roll 40 at least once, operates the brake 6 on the roll 5. This causes the sheet 10 to tear from the main web 5 along the line of weakness 27. By this time the line of weakness is adjacent the roll 40, so that as it tears the leading edge of the next sheet 10 is held by spring blades 26. Further rotation of the belts 3, 4 causes the torn end of the sheet to be glued down and the entire belt 4 is then moved upwards and the wrapped roll ejected by an arm (not shown). The speed of rolling of the strip as well as the wrapping of the sheet about the rolled strip may be controlled by an electrical contact actuated by the element which cuts the strip. The invention is particularly applicable in the manufacture of mats made of glass fibres or similar mineral materials.

Title: Improvements in or relating to the preparation of d-tartaric acid

Abstract: 538,945. Tartaric acid. PFIZER & CO., C. Dec. 8, 1939, No. 31847. Convention date, Dec. 13, 1938. [Class 2 (iii)] d-Tartaric acid is produced by oxidizing 5-keto-d-gluconic acid or its salts by means of an oxidizing agent which may be selected from a soluble hypobromate selenium dioxide, mercuric and cupric oxides and mercuric and cupric oxides used alone or oxygencontaining gases or soluble chlorates alone or together with a catalyst consisting of an oxide of vanadium, cobalt, manganese, titanium, molybdenum, chromium, iron cerium, nickel, uranium or tungsten or a soluble salt of an acidic oxide of one of these metals. The reaction may be effected under acid or alkaline conditions, at pH 0.1 to 14, preferably below 80‹ C. Examples describe the oxidation by means of (1) potassium hypobromite (or anodic oxygen in the presence of a bromide and excess of alkali) ; (2) ammonium vanadate and potassium chlorate ; (3) finely-divided oxygen ; (4) and (5) finely-divided oxygen and vanadium pentoxide ; (6) manganese dioxide in the presence of nitric acid which is used to adjust the pH ; oxides of the other metals mentioned may be used instead of the manganese oxide.

Abstract: 1,112,015. Creasing &c. machines. HARRISINTERTYPE CORPORATION. 26 July, 1965 [15 Sept., 1964], No. 31875/65. Headings B6C and B6J. [Also in Divisions B4 and F2] In machines such as creasing or cutting machines, wherein during their operation, pressure between co-operating cylinders 10, 11 varies because of gaps in the cylinders or during the interval between the passage of one sheet and the next, means are provided inwardly of their bearings to load the cylinders away from one another so as to prevent undesirable movement of the cylinders due to the pressure variation. Impression adjustment and tripping.-A reduced part of the shaft 10a of cylinder 10 is mounted in roller bearings the inner race 30 of which is fixed to the shaft. The outer race 31 is mounted in an eccentric 24 so as to be capable of limited axial movement with respect thereto for permitting axial adjustment of the cylinder as described below. Rotation of the eccentric in the side frame 20 to move the cylinder 10 to and from operative position is effected by a fluid pressure device (26, Fig. 1) and linkage(27), one of the links being adjustable in length to adjust the operative position of the cylinder 10. The other cylinder 11 is mounted in fixed bearings 23. Cylinder loading.-Between the bearings and the cylinders, the shafts are encircled by members 49, 50 with interposed roller bearings 51, 52. The members 49, 50 have enlarged holes engaging bolts fixed to the side frames 20 so as to permit free radial movement of the members. Flat inner faces 49a, 50a on the members are engaged by similar faces on two members 64, 65 separated by springs 71. Bolts slidably connect the pressure members 64, 65 and are adjusted so that they take the pressure of the springs 71 before the cylinder 10 reaches its tripped position, thus permitting the devices 64, 65, 71 to be removed or inserted as a unit. Wedges, screws or fluid-pressure devices may be used instead of springs to provide the loading. Axial adjustment.-A bracket 40 fixed to the end of the shaft 10a has an annular rib 45 engaged by shoulders 43, 44 on a spindle 37 having threaded engagement with a cover member 47 fixed to the eccentric 24. Rotation of the spindle 37 by a knob 36 effects axial adjustment of the cylinder 10. Framing.-Each side frame 20 comprises three parts (20a, 20b, 20c, Fig. 1), connected by bolts and having abutting surfaces along horizontal planes through the centres of the openings in the frame which receive the eccentric 24 and the bearing for the cylinder 11 thus permitting easy assembling and dismantling of the machine.

In an electric analogue-to-digital converter an angular movement, for example the movement of the indicating needle 4, Fig. 1, of a voltmeter, is converted into a combination (either serial or parallel) of two-state markings, each marking being an A.C. signal either in phase or 180 degrees out of phase with a reference signal, by means of a ferromagnetic strip 8, Figs. 1 and 2, joined to the needle, which co-operates with 132 E-section transformers 10 which have one winding 27a, 27b which embraces every core and seven other windings 20-26 wound around the centre bar of the " E." The windings are so wound (see Figs. 3 and 4, not shown) that if A.C. current is applied in succession to the seven windings 20-26 then seven voltages are successively induced in the common winding 27a, 27b, by virtue of the inductive coupling produced by the strip 8, and these voltages, by their phases, indicate, in a monophylic binary code, the angular position of the strip 8. Alternatively an A.C. current can be applied to the common winding 27a, 27b to produce a combination of A.C. voltages in the seven windings 20-26.
