Title: Improved method of and apparatus for making glass
IPC: C03B5/04
Filed: 1932-07-27
Abstract: 405,012. Glass - melting tanks' SIMPLEX ENGINEERING CO., Washington Trust Building, Washington, U.S.A.- (Assignees of Amsler, W. O.; 1665, Watova Road, Toledo, Ohio, U.S.A.) July 27, 1932, No. 21194. Convention date, July 28, 1931. [Class 51 (ii).] Glass is melted and refined in a tank comprising melting and cooling compartments connected by a neck, by maintaining a " hot spot "of predetermined temperature, say 2650‹ F., at a point in the melting-compartment nearer the neck end than the charging-end, and a " cool spot " at a temperature of say 2300‹ F. at the discharge end of the cooling-compartment. The surface of the glass is continuous throughout the length of the tank, and free circulation of the glass is set up between the " hot spot " and the two ends of the tank. The furnace shown comprises a melting compartment M to which the batch is fed through dog houses 18, a cooling- compartment C connected to the melting compartment by a neck N defined by inwardlyextending bridges 11, 12, and a tempering compartment T from which the glass is drawn at the feeder F. The bridge walls preferably extend to the surface of the glass, and above this the two compartments are separate by a chequer work wall 14 of silica bricks, which may be laid without cement, so that the form of the wall can be changed to vary the amount of heat radiated from the melting to the cooling compartment. The walls of the latter compartment are of materials having good heat dissipating properties such as silica brick, and the floor is preferably raised above that of the melting-compartment, the raised portion extending a short distance through the neck. The furnace is fired from the feeding-end by a horse-shoe frame, and the firing is controlled to give a hot spot at a point not less than 60 per cent of the length of the melting-compartment from the feed end. The width of the neck is preferably about 20 per cent, but may be between 10 per cent and 35 per cent, of the width of the melting-compartment. A large output tank is described in which the glass is fed to a number of drawing-compartments.

Title: Ceramci pigments based on zirconium silicate
IPC: C03C1/10
Filed: 1973-05-04
Abstract: 1403470 Ceramic pigments DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 4 May 1973 [5 May 1972] 21271/73 Heading C1M A ceramic pigment comprises a sulphide, selenide or telluride of zinc, cadmium or mercury or a mixed crystal thereof, incorporated as a separate phase into transparent zirconium silicate crystals. The transparent zirconium silicate may be coloured, e.g. by doping with praseodymium or vandium. Particularly intense pigments are obtained when the sulphides, selenides and tellurides or their mixed crystals are formed during synthesis of the zirconium silicate. Zinc, cadmium, mercury and sulphur, in the form of their oxygen containing compounds, are preferably used as starting materials for this purpose. Sodium sulphite and sodium thiosulphate are particularly suitable sulphur donors. For example when a mixture of ZrO 2 , SiO 2 , CdO, S and Se is calcined under conditions which allow the formation of zirconium silicate (i.e. temperatures up to 600‹ C. in the presence of a mineralizer, e.g. LiF, or up to 1100‹ C. in the absence of a mineralizer) zirconium silicate and cadmium sulphide selenide are formed. Sodium zirconium silicate may also be used for the synthesis of the zirconium silicate. Numerous cadmium compounds, e.g. CdCO 3 , CdSO 4 , CdO, CdS, CdSe and sulphur/selenium containing compounds, e.g. Na 2 SO 4 , Na 2 SO 3 , Na 2 S 2 O 5 , Na 2 S 2 O 3 , Na 2 S 2 O 4 , Na 2 S or the corresponding selenium salts and their mixed crystals are specified. Reducing agents, e.g. sugar and starch, may be added and the colour of the Cd(S x Se 1-x ) inclusions may vary from yellow (x = 1) through orange, light red and dark red to black (x = 0). Light yellow pigments are formed when mixed crystals of CsS and ZnS with up to 50 mol per cent of Zn are incorporated into the zirconium silicate and orange coloured pigments are formed where mixed crystals of CdS and HgS with up to 100 mol per cent of Hg are incorporated.

Title: ª+-carbolines and process for their manufacture
IPC: C07D471/04
Filed: 1958-07-03
Abstract: The invention comprises 1-hydroxy-g -carbolines which are 9-substituted by an alkyl or amino-substituted alkyl group having 1-5 carbon atoms or a benzyl group and quaternary compounds thereof and also pyrido-[2 : 1-b]-g -carbolinium compounds which are 11-substituted by an alkyl or amino-substituted alkyl group having 1-5 carbon atoms or a benzyl group, and 12-substituted by an alkyl group having 1-5 carbon atoms; and also a process for producing N-substituted g -carbolines in which an a -indolyl-lithium compound, which is N-substituted by an alkyl or amino alkyl group having 1-5 carbon atoms or a benzyl group and is otherwise unsubstituted or contains a tertiary aminomethyl group in b -position, is first reacted with an a -amino-aldehyde or -ketone, the nitrogen atom of which is tertiary, the indole compound so formed is reacted with formaldehyde and a secondary amine, the Mannich base produced is treated with a quaternating agent or a strong acid, and the resulting monoammonium compound is heated with the splitting off of an amine and formation of the g -carboline ring.  The reaction when 1-methyl-indolyl-(2)-lithium and diethylamino acetone are used as starting materials, takes place as follows <FORM:0892618/IV (b)/1> <FORM:0892618/IV (b)/2> <FORM:0892618/IV (b)/3> <FORM:0892618/IV (b)/4> <FORM:0892618/IV (b)/5> <FORM:0892618/IV (b)/6> The reaction between the indolyl-lithium compound and the amino-aldehyde or -ketone is preferably carried out in an inert solvent, e.g. ether, dioxane or benzene.  The basic nitrogen atom of the a -amino-ketones and -aldehydes may belong to a heterocyclic ring, e.g. a pyridine, piperidine, pyrrolidine, piperazine or morpholine ring.  The nitrogen may alternatively carry alkyl, aralkyl or cycloalkyl groups. Suitable quaternating agents for treating the Mannich bases are, for example, alkyl halides and sulphates, and suitable acids are, for example, hydrochloric acid, sulphuric acid or toluene sulphonic acid. The mono-ammonium compound may be boiled in a solvent, such as water or tetrahydronaphthalene, to bring about the formation of the g -carboline ring.  The ammonium salts may be converted by known methods into other ammonium salts.  Examples are given of the preparation of (a) 1 : 9-dimethyl-1-hydroxy-3 : 3-diethyl-1 : 2 : 3 : 4-tetrahydro-g -carbolinium iodide of formula <FORM:0892618/IV (b)/7> which on heating gives 1 : 9-dimethyl-3-ethyl-g -carbolinium iodide; (b) 5 : 5-diethyl-11-methyl-11b-hydroxy-1 : 2 : 3 : 4 : 4a : 5 : 6 : 11b-octahydro-benzo(a)-g -carbolinium iodide of formula <FORM:0892618/IV (b)/8> which on heating gives 5-ethyl-11-methyl-1 : 2 : 3 : 4-tetrahydro-benzo-[a]-g -carbolinium iodide of formula <FORM:0892618/IV (b)/9> (c) 1 : 9-dimethyl-1-hydroxy-3-benzyl-3-ethyl-1 : 2 : 3 : 4-tetrahydro-g -carbolinium iodide of formula <FORM:0892618/IV (b)/100> which on heating gives 1 : 9-dimethyl-3-ethyl-g -carboliniu iodide; and (d) 11 : 12-dimethylpyrido-[2 : 1-b-]g -carbolinium iodide of formula <FORM:0892618/IV (b)/111>

Abstract: 1,123,893. Friction clutches. SOC. ANON. FRANCAISE DU FERODO. 13 May, 1966 [14 May, 1965], No. 21440/66. Heading F2C. In a friction plate clutch, springs 18 acting between axially fixed cups 19 and an axially displaceable presser plate 13 are endowed, when at lest, each with a convex form towards the clutch axis by inclined spring seats cast on the presser plate, as shown and in Figs. 6, 7 (not shown), stamped or punched on the cups, Fig. 8 (not shown), or formed on both the presser-plate and the cups, Fig. 10 (not shown), so as to compensate for deformation due to centrifuging of the springs and thereby prevent contact between the springs and the cups at high driving speeds. The springs 18 are centred at one end by pegs 22 on the presser-plate, and at the other end by cup constrictions 23, as shown, or cup inturned flanges (27), Figs. 6, 7 (not shown). The cups have retaining flanges 25 and are engaged in holes 24 in a cover 20 bolted to the driving flywheel 10. In Figs. 8 10 (not shown), correct inclined seat cup orientation is maintained by peripheral cup projections (28) engaging cover notches 29. If, although not preferred, the endowed convexity is sufficient for spring and cup contact at rest, the cup insides may be surface hardened, as by cyaniding (e.g. in baths of salts), carbonitriding, gaseous annealing, or metal depositing (e.g. hard chromium or nickel tin, chrome plating or accelerated nitriding), and/or friction between spring and cup may be reduced, as by lubrication, phosphatation, sulphinuzation, soft nitriding, metal depositing (e.g. nickel tin), or application of MOS 2  in powder, grease or varnish form. The cups are formed, by folding, cutting or stamping, before treatment. In Fig. 7 (not shown), the spring turns are of square cross-section for better resistance to deformation. The presser-plate 13 is coupled for rotation with the flywheel 10 as by mortise and tenon, or tangential straps, and is moved for clutch release as by levers and a thrust bearing.
