Title: Improvements in the manufacture and production of aromatic hydrocarbons of low boiling point by hydrogenating coal tar fractions
IPC: C10G47/00
Filed: 1933-12-09
Abstract: In obtaining low-boiling aromatic hydrocarbons from high-boiling hydrocarbon liquids consisting of or containing aromatic hydrocarbons and derived from mineral coal, such as coal tar fractions, or heavy benzene obtained by destructive hydrogenation of mineral coal, the liquids are first refined by a heat-treatment in presence of hydrogen under conditions to remove sulphur and oxygen compounds and to hydrogenate some of the double bonds without decomposition into lower molecular compounds.  The treatment is effected at pressures above atmospheric, e.g. 20 atmospheres or more, and at temperatures of 100--450 DEG  C. in presence of sulphurimmune catalysts.  The liquid may be heated to about 200 DEG  C., passed into a separator from which polymerized constituents are removed, and the remaining product be led with hydrogen over a heated catalyst.  The material may be passed at 100--300 DEG  C. under pressure over a hydrogenation catalyst such as the sulphides of metals of the 5th to 8th group, and then at 300--475 DEG  C. over a catalyst consisting of oxides or sulphides of metals of the 5th and 6th group, at pressures up to 500 atmospheres.  The refined product is led with hydrogen under 100--500 atmospheres pressure and at 500--700 DEG  C. over catalysts such as compounds of the metals of 2nd to 8th groups. Specification 328,618, [Class 32], is referred to.

Filed: 1935-12-14
Abstract: In making grained or veined articles having the appearance of marble, tortoise-shell, horn, wood, &c. from artificial resin by pressing, the usual tablets formed from the pressing powder are divided up according to the desired veining or graining, e.g. by a profiled cutter, and to the parts so obtained there is applied by spraying, powdering, &c. a pigment or pigments, the parts being then subjected to hot pressing to give the article or, more particularly in the case of small articles such as buttons, to form another tablet from which the article is pressed in a mould. In a modification, the pigment is applied to the undivided tablet from which the articles are then made.  In a further form, the pressing powder is formed into bars which are divided into small parts which are coated with the colour and formed into tablets which are subjected to hot pressing.

[Also in Division F1] In a butterfly valve 11, the closure 18, within a circular passage 13 of a cast iron housing 12 installed between the exhaust manifold and exhaust inlet pipe of an internal combustion engine, is mounted by welds 19 to an offset transverse pivot 16 and is formed as a central channel section 26, 28 with two circular segmental flange elements 27 which shield the bearings 15 from exhaust gases and enable the closure 18 to be rotated to the open position without contacting the wall of the passage 13. At low temperatures the butterfly valve is held in its closed position by a spring 22 and deflects exhaust gas along a conduit (not shown) to heat the inlet manifold and, at higher temperatures, the spring 22 is weakened to permit the closure member 18 to rotate to the open position under the action of a counter-weight 21. A coil spring 42 encircles the anchor pin 23 of the spring 22 and abuts the counter-weight 21 to absorb rotational energy of the butterfly valve.

In a reciprocable, cooled, continuous casting mouldhaving a plurality of adjacent mould cavities 13, 14 and 15, each cavity is separated by a partition 16 which has an interconnecting passage 18. The passages 18 are provided in replaceable inserts 17 formed of refractory material such as graphite positioned at the upper end of the mould and which form a continuation of the partitions 16. The lower portion 21 of the insert is provided with heating means 24 in the form of an electric element or induction coil so as to prevent freezing of the molten metal at the insert level. In use, molten metal is poured into one of the cavities and when the level reaches the passage 18 the metal overflows into and adjacent cavity so as to eventually fill all the cavities in the mould, whereupon the casting operation is initiated. The casting and pouring rates are so determined as to always maintain the meniscus 20 above the base level of the insert during the casting operation. In an alternative embodiment, the top of the mould which contains the interconnected passages is made as a separate part of refractory or graphitic material and the heating means may be provided in the form of an electro-conductive material located in grooves around the top of the mould cavities, Fig. 7 and 8 (not shown). In a further embodiment, Figs. 3 and 4, the partition between the mould cavities is formed entirely by a replaceable insert 30.
