1.WO/2001/077021PRODUCTION OF STRONTIUM CARBONATE FROM CELESTITE

WO - 18.10.2001

Класс МПК C01F 11/18 № заявки PCT/TR2000/000020 Заявитель TÜBITAK-MARMARA RESEARCH CENTER Изобретатель KOCAKUŞAK, Sidika

The main and commercial minerals of strontium are celestite and strontiyanite. The most common of these two minerals is celestite, which is strontium sulfate. The other mineral is mainly strontium carbonate and its occurrence is rare. Therefore pure strontium is mostly produced from celestite which is then used in production of glass suitable for production of color television tubes, in electro ceramic industry and in production of electrolytic metals. There are two main processes for economical production of strontium carbonate from celestite in industrial scale. These processes are reduction process (Black Ash). BA and direct conversion to carbonate and/or double decomposition process, DD. Although there are some processes using ammonium carbonate for double decomposition, the majority of the DD processes use sodium carbonate for conversion to carbonate. In the novel process developed, celestite is converted to strontium carbonate via double decomposition with ammonium carbonate. The obtained strontium carbonate contains some impurities and is called as raw strontium carbonate. To purify the raw strontium carbonate is then calcinated to obtain strontuim oxide, which is then converted to strontium hydroxide solution by reaction with water. Strontium hydroxide solution is filtered to get rid of the insoluble impurities. From the filtered and purified strontium hydroxide solution, pure strontium is precipitated out by reacting the solution with carbondioxide. The precipitated strontium carbonate is then separated and dried as powder form. The solution obtained from double decomposition contains both ammonium carbonate and ammonium sulfate. By increasing the temperature of this solution to a suitable value, ammonium carbonate is decomposed to ammonia and carbondioxide to be recycled to the process. Since the remaining solution is ammonium carbonate free, ammonium sulfate is crystallized from it as a commercial product or is reacted with milk of lime to recover ammonia.

WO - 26.10.2023

Класс МПК A61C 7/02 № заявки PCT/SY2022/050001 Заявитель RAGHIS, Tuqa Rashad Изобретатель RAGHIS, Tuqa Rashad

A custom-made appliance designed for total distalization of the upper dental arch. It consists of a Vitallium bar with two posterior holes for mini-screws' insertion localized at the para-median area, and two extended lever arms with two posterior hooks. The palatal plate should be applied with a stainless steel anterior trans-palatal arch, which is inserted in the palatal tubes of the maxillary first molars' bands and provided with two anterior soldered hooks. Distalization of the upper arch can be accomplished by applying an elastic chain or closed coil spring from the anterior hooks of the trans-palatal arch to the posterior hooks of the palatal plate.

4.WO/2002/089559APPARATUS FOR ASSIMILATION LIGHTING AS WELL AS FIXING SYSTEM AND METHOD FOR INSTALLATION THEREOF IN A GREENHOUSE

WO - 14.11.2002

Класс МПК A01G 9/26 № заявки PCT/NL2002/000304 Заявитель MICHIEL VASTGOED EN MANAGEMENT B.V. Изобретатель DOOL, VAN DEN TEUNIS, Cornelis

The invention relates to an apparatus for assimilation illumination for installation in a greenhouse to cultivate light sensitive plants. The invention also relates to a mounting system and method upon which the illumination armature (6) will be installed. Illumination armature (6) with light source will be installed up in the ceiling section of a greenhouse structure. The accessory starter unit (14) will be located lower, in the proximity of the plant(s). By the application of this unique separated configuration there will be substantially less light interception as well as improved balanced temperature profile in the greenhouse space will be achieved. These are due to the heat generated by starter units that is now being utilized on a much lower level in a greenhouse. Supporting suspension elements, like steel wires, are mounted in the ceiling section (1) of a greenhouse structure. Illumination armature (6) is provided with special L-shaped holding means (7) and accessory connection piece (8). Illumination armature (6) is by means of a pair of metal- or synthetics made braces supported (hanged) upon a pair of parallelly running supporting steel wires. Fixing of the illumination armature (6) upon a pair of steel wires is obtained by fastening of a single brace. Undesired warping of illumination armature (6) at operating and non-operating times will be avoided accordingly. A chance for theft will be also reduced.
