Title: Apparatus for making thin ceramic plates by extrusion
IPC: B28B11/16
Filed: 1952-12-05
Abstract: 722,981. Extruding thin flat ceramic plates. ERIE RESISTOR CORPORATION. Dec. 5, 1952 [March 19, 1952]. No. 30959/52. Class 87 (2). Relates to the production of plates about 1/100 inch thick from barium titanate or like ceramic material, for use in electrical devices, by extruding a ribbon which is cut while plastic into the desired lengths and which is of uniform density so that no strains are in the material which would cause it to warp during filling. The extrusion die is constructed so that all the particles flow through its orifice at the same speed with no tendency for faster or slower movement at its centre and edges respectively. The throat of the die tapers down from its entrance 2 to its orifice 1. At the centre Fig. 2 (section 2-2 in Fig. 1) the upper and lower sides of the die throat are built up, at 4, to provide a friction-increasing resistance, and at the edges, Fig. 4 (section 4-4 in Fig. 1) the throat is enlarged to provide friction-relieving .hollows 7a. On an intermediate section 3-3 the throat tapers evenly to the orifice. By thus varying the taper the throat is adjusted so that the friction in the throat upstream of the orifice plus the friction in the orifice is constant across the width of the orifice. The ceramic is discharged from the extruder 8, Fig. 6, in the form of a ribbon 9 onto a belt 10 which travels at the same speed as the ribbon. Guides 11 along opposite sides of the felt have diverging sides 12 defining slots 13 for cutter wires 14 carried by a rotating reel 15. The extruder is preferably provided with a vacuum connection for removing air.

Patent GB-311716-A (GB)
IPC: C09F9/00
Abstract: 311,716. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 14, 1928. Driers; paints.-Driers for paints, varnishes, &c. are obtained by treating crude or saponified oxidation products of waxes such as paraffin or montan wax, with one or more metallic compounds to form products insoluble or only sparingly soluble in water, and adding, if desired, metal salts of high molecular acids of natural origin. A fraction, such as one obtained by distillation, may be used instead of the crude oxidation products. The oxidation products consist mainly of organic acids of high molecular weight and some unsaponifiable matter &c. The unsaponifiable constituents are preferably removed by treating or saponifying the crude product with alkali such as caustic soda, ammonia &c., separating by settling and treating the alkali salts of the acids present, preferably at an elevated temperature with metal compounds such as oxides or salts of the alkaline earths, aluminium, zinc, manganese, copper, mercury, cobalt, lead &c. or mixtures thereof. The paste-like products, to be used as driers, are soluble in organic solvents such as turpentine, benzine, oils such as linseed oil &c. The products may be mixed with metal salts of high molecular organic acids of natural origin, such as resinates, oleates, stearates, naphthenates. Such mixtures may be prepared from their components by precipitating the metal salts of such acids conjointly with those of the oxidation products. Thus the saponified oxidation products may be mixed with saponified or saponifiable fats, oils, resins &c. and the whole treated with metal salts. The driers may be melted with resins, linseed oil, wood oil etc.; they may also be used for anti-corrosive purposes in paints &c.
