Title: Improvements in or relating to coloured granules, composition roofing employing said granules and methods of making said granules
IPC: E04D7/00
Filed: 1948-11-05
Abstract: Coloured granular material comprises individual granules each of which is coloured by pigments bonded thereto by means of a substantially water insoluble metallic metaphosphate finder.  The material is prepared by mixing the granular material base in an aqueous solution of a mono-metallic orthophosphate and a pigment and then heating the product to convert the orthophosphate to the corresponding metaphosphate, this heating being sufficient to molecularly dehydrate the orthophosphate but preferably not sufficient for fusion.  Alternatively the aqueous solution of the orthophosphate is applied to the granular material and then the pigment adhesively bonded thereto by mixing the phosphate but preferably not sufficient for two materials together.  Specified orthophosphates are those of aluminium, iron magnesium and a mixture of those of sodium and potassium.  Specified pigments are oxides of iron, chromium, cobalt, titanium, manganese, red oxide of lead, amber and ultramarine.  Organic pigments which do not react with the orthophosphate may also be used.  Specified granular materials are calcium silicate slags, blast furnace slags, broken or crushed rock and shale, trap rock, quartzite, quartz, flint, granite, green stone, slate, argillite, burnt clay, and crushed brick.  When calcium silicate slag is used a pretreatment with phosphoric acid of at least 70 per cent strength or with an ammonium orthophosphate should be employed.

Title: Apparatus for stretching thermoplastic films
IPC: B29C55/16
Filed: 1962-07-27
Abstract: 1,012,171. Stretching films. GEVAERT PHOTO-PRODUCTEN N.V. July 27, 1962 [July 28, 1961], No. 29038/62. Heading B5B. Apparatus for stretching thermoplastic film at raised temperature comprises means for progressively transversely stretching a length of film in a stretching zone while such film is continuously conveyed therethrough, heating means in said zone for radiating heat towards the film over the whole of said zone, and means for regulating the heating to which the film is subjected by said heating means at different parts of said zone, said regulating means comprising a plurality of elongated heat absorbing and/or reflecting elements, and holders for holding such elements in said zone in laterally spaced relationship across the width of said zone so that their longitudinal axes mutually diverge in the general direction in which film travel through the said zone takes place, the said holders permitting the number and spatial distribution of such elements across the film path to be readily varied. Preferably, the elements are held in position in said zone so that the angle at which each element is inclined to the longitudinal axis of the film path through said zone is such that the lengthwise direction of said element corresponds with the direction in which the film portion immediately opposite the element moves when the apparatus is in use. The elements may be flat strips, and may be heat reflecting elements positioned between a heat source and the film. Alternatively, said means may comprise a heat source on one side of the film and a reflector on the other side for reflecting heat over the whole zone, and the heat-regulating means may comprise heatabsorbing elements located between such reflector and the film. The elements may be arranged in two or more groups disposed behind and/or one above the other in the stretching zone. In apparatus as shown, a melt is extruded on to roll 1 to form a film, with beaded edges, which is longitudinally stretched between feed rolls 1, 2, 3 and draw rolls 6, 7, 8 and simultaneously transversely stretched while passing between the guide members of the frames 4 and 5. While in the stretching zone II the film is heated by an infrared heater 9. Six pairs of transverse bars 11-16 arranged in three groups a, b and c and two planes x and y support a number of heatreflecting plates in the zone between the heater and the film. Each element is mounted by means of pins 12, according to an angle α corresponding to the stretching angle # formed by the centre-line of the film and the course of the film part passing under the respective reflecting element. The reflecting elements can thus easily be mounted and removed, the number and location of the reflecting elements being determined from observation of thickness variations in the stretched film. In this way films having better uniformity of thickness may be obtained. An example describes the treatment of polystyrene film. Specifications 585,164, 746,386, 959,449, 959,450 and U.S.A. 2,718,658 are referred to.
