Title: Process for the separation of beryllium compounds from minerals or substances containing beryllium by chlorination
IPC: C22B1/08
Filed: 1930-07-14
Abstract: Ores or other substances containing beryllium are treated at say 1,000 DEG  C. with chlorinating gases in the absence of any reducing agent to form and volatilize beryllium chloride or oxychloride.  If other metals present are chlorinated separation is effected by fractional volatilization; for instance, iron, if present, is removed by preliminary treatment with chlorine at 800-900 DEG  C.  Substances treated may comprise oxides, silicates, and aluminosilicates of beryllium, or oxidized alloys containing beryllium, and chlorine or hydrochloric acid may be used for the chlorination, which may be effected under increased or reduced pressure.  By introducing air or oxygen into the issuing gases, preferably in countercurrent thereto, preheated, and under pressure, beryllium oxide is directly obtained. Otherwise the chloride or oxychloride formed may be dissolved in water, and beryllium hydroxide be then precipitated out.  Internal or external heating of the reaction chamber, comprising clay, alumina, or quartz sand, may be effected, or the chlorine &c. may be preheated, for instance electrically.

Title: Improvements in supporting devices for electrical conductors
IPC: H02G7/05
Filed: 1928-07-26
Abstract: 294,881. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Wahlberg, N. A.). July 30, 1927, [Convention date]. Clips and holders for cables and conductors.- A clamp for an overhead electric conductor comprises means which, on the breaking of the conductor between spans, will release the conductor. In the embodiment, the clamp comprises a channel piece 2 for supporting the conductor 3, a clamp shoe 4 carrying a leaf-spring 5, a cam mounted between arms 8 on the piece 2, a yoke 10, trunnions 12 on the piece 2, and a structure 14 for mounting the trunnions 12 relative to the yoke 10 and the piece 2. A pin 37 projects from a socketmounting part 36 of the yoke 10, and fits between arms 30 on the cam 7. The structure 14 consists of links 39, preferably integral with the trunnions 12, and connected together by a bolt 40 passing through an apertured portion 19 of the piece 2. In mounting the conductor, it is passed between the sides of the piece 2 to the position shown, and the shoe 4 with the spring 5 is passed into position between the arms 8. The cam 7 is inserted and centred by arcuate portions 44 on the arms 8. After the cam-securing pin 31 has been placed in position, the cam is turned so that the portion 29 depresses the spring 5 to clamp the shoe 4 against the conductor. The trunnionbearing links 39 are then assembled with the yoke 10 and passed over the sides of the channel so that the pin 37 lies between the cam-arms 30, and the bolt 40 is placed in position. In operation, play between the pin 37 and arms 30 allows the piece 2 and yoke 10 to oscillate relatively in response to ordinary line movements, but if the conductor breaks, causing the insulator string which carries the clamp to swing through a large angle, the pin 37 engages an arm 30 to release the shoe 4. The conductor 3 then slips through the member 2 until the deflecting force on the insulator is reduced, the clamp then tending to resume the normal operative position.

Title: Process for the catalytic hydrogenation of aromatic hydrocarbons
IPC: B01J23/74
Filed: 1966-05-17
Abstract: Aromatic hydrocarbons or aromatic-containing hydrocarbon fractions are hydrogenated at elevated temperature and hydrogen pressure in the presence of a catalyst comprising as the carrier silica/magnesia and as the hydrogenation component at least one sulphide of tungsten, molybdenum or rhenium and/or at least one sulphide of a Group VIII metal.  The catalyst may also contain a minor amount of a corresponding oxide of one of the said metals. A particularly suitable catalyst comprises both tungsten sulphide and nickel sulphide on silica/magnesia. When the starting material contains sulphur-impurities these need not be initially removed, since desulphurization takes place simultaneously with the hydrogenation without affecting the product yield.  The process may be used to hydrogenate benzene or to lower the aromatic content in hydrocarbon fractions such as gasoline, kerosene, gas oil or lubricating oil.
