Patent GB-852825-A (GB)
Title: A process for the manufacture of gypsum
IPC: C01F11/46
Filed: 1957-02-15
Abstract: <PICT:0852825/III/1> Gypsum is produced by reacting phosphate rock with sulphuric acid, and then charging the calcium sulphate hemihydrate sludge thus produced into the top of an upright conversion tank in which hydration to gypsum takes place, the sludge descending through the tank without stirring, the height of the tank being so related to the flow rate of the sludge that the hydration is completed by the time the calcium sulphate reaches the bottom of the tank.  No stirring or agitation is effected in the tank.  In an example (see the Figure), powdered phosphate rock is charged into tank 1, where it is opened up with phosphoric acid recycled from separator 9.  The resulting material is reacted with sulphuric acid at 80 DEG C. to 90 DEG C. in tank 2, and the resulting sludge, containing calcium sulphate hemihydrate and phosphoric acid, is passed to the top of tower 5 via tank 3, in which its temperature is adjusted to about 65 DEG C.  The sludge is allowed to sink under its own weight, and from the bottom of the tower 5 is withdrawn gypsum and phosphoric acid, at a temperature of about 40 DEG C.; these are separated in centrifugal separator 7, the gypsum washed in tank 8 and again separated in centrifugal separator 9, from which the liquid phase, containing phosphoric acid, is recycled to tank 1.

Filed: 1964-02-07
Abstract: 1, 042, 563. Filters; magnetic separators. D. BOTSTIBER. Feb. 7, 1964, No. 5336/64. Headings B1D and B2J. A liquid filtering device comprises a perforated metallic screen 68 through which all liquid passes between inlet 64 and outlet 66, and magnetic elements 76 which establish a magnetic field between them and a sleeve 72 of paramagnetic material so causing magnetizable particles to build up on the sleeve and screen. An electrical circuit, in which the magnetic elements are included has an indicating device 86 actuated whenever a large electrically conducting particle or an accumulation of such particles completes a conducting path for the current between the sleeve 72 and any one of the magnetic elements 76. The magnetic elements have spaced arms 76 with openings therebetween for liquid flow, and adjacent plates are oppositely polarized. They are held apart by metal spacers on a metal rod 78 which is connected through the indicator 86 and an electric current source 88 to earth, the metal housing 60 being earthed at 92. The indicating device 86 may also be actuated in response to a flow failure within the filter by means of a valve unit 89 earthed at 102. Normally in response to liquid pressure a check valve 98 is urged away from the unit 89, but whenever liquid pressure ceases the check valve is closed under the action of a spring 100 so providing a conducting path for flow of current and causing the actuator of the indicating device. The valve unit 89 also has a pressure responsive valve 104 which normally closes ports 106 under action of a spring 108 but moves under excessive pressure due to clogging to open ports 106. This movement causes valve 104 to engage a contact element 110 or rod 78 and complete a circuit through the indicator 86.

Title: Improvements in derivatives of stilbazoline
IPC: C07D211/26
Filed: 1952-02-29
Abstract: The invention comprises bis-quaternary stilbazolinium salts of the formula <FORM:0703961/IV(b)/1> where R and R1 are alkyl of 1-4 carbon atoms, one being methyl, S denotes saturation of the ring and X is the anion of an acid.  These are made from N-alkyl-41-dimethylamino-g -stil - bazoline hydriodides by (1) conversion to free base and treatment with 2 mols. of methyl iodide to give the product (R1 = methyl); or (2) addition of one mol. of R1, conversion to free base and treatment with one mol. of methyl iodide.  Alternatively N-alkyl-41-methylethylamino-stilbazoline hydriodide may be used as starting material; this is obtained from an alkyl-g -picolinium iodide and p-methylethylaminobenzaldehyde followed by catalytic hydrogenation.  The above processes yield products where X is iodide; other salts may be obtained by using a different quaternating agent (e.g. a bromide or sulphate) or by subsequent conversion, e.g. into chlorides and nitrates.  Examples show the production of compounds (1) R = R1 = methyl, X = iodide, converted into chloride, (2) R = ethyl, R1 = methyl, X = iodide, (3) R = methyl, R1 = ethyl, X = iodide.  R or R1 may also be n-propyl or n-butyl.

Title: Improvements in or relating to the production of concrete
IPC: E01C19/02
Filed: 1943-04-09
Abstract: Concrete roads are made by laying stone on a bed to a height slightly greater than that finally required and applying grout to a level below the surface of the stone, but sufficient to rise to the surface of the stone and form a surface dressing when the stone is consolidated by rolling on tamping.  The amount of grout used is sufficient to fill the voids in the stone if they amounted to 30 per cent instead of the usual 45 per cent.  When only small stones are to be used, these are built up into ridges across the base surface, grout is placed in the intermediate sections, and the stones are spread over the grout until the desired height is obtained. Specification 412,556 is referred to.  According to the Provisional Specification, a base of large stones is laid to a lower level than the desired finished surface, grout is applied to fill the voids, and smaller stone is then scattered over the surface and tamped in.
