Title: Improvements in the electrolytic treatment of metals and alloys for the removal of metal from the surface thereof
IPC: C25F3/00
Filed: 1955-09-01
Abstract: 810,475. Electro-polishing metals and padtype apparatus therefor. CHARLESWORTH, P. A. Nov. 29, 1956 [Sept. 1, 1955], No. 5972/55. Class 41. In a process for the electrolytic polishing or other electrolytic treatment for the anodic removal of metal from the surfaces of metals and alloys the cathode is located very close to the surface during treating, but is separated therefrom by a layer or layers of porous and non-conducting material, the said cathode and the porous and non-conducting material being located in a housing which can be moved over the surface or through which the surface can be traversed and which is provided with an inlet through which a sufficient quantity of electrolyte can be supplied to keep the surface bathed therewith, and a high degree of local turbulence of the electrolyte in the neighbourhood of the highs pots of the area of the surface being treated is caused by a sufficiently high relative movement between the cathode and the surface. Suitable non-conducting porous material is glass wool, fabric made from polyethylene terephthalate or similar synthetic fibres or a perforated sheet of rubber or plastic. As shown in Fig. 1 a perforated cathode C is located in a casing E<SP>1</SP>, open on the underside, to which electrolyte E is supplied through inlet e. A non- conducting blanket B is arranged between the cathode C and the workpiece (anode) A. In use the cathode assembly is moved over the surface of the workpiece the movement of the blanket B creating turbulence in the electrolyte in the neighbourhood of the high spots a. As shown in Fig. 2 the cathode is in the form of a roller having a central portion D of conducting material with an outer covering D<SP>1</SP> of non-conducting porous material. The roller is journalled in a casing E<SP>1</SP> to which electrolyte E is supplied through inlet e. In a further arrangement (not shown) the workpiece in the form of a sheet is pulled through a fixed pair of insulating blankets backed by cathodes in a stationary housing to which the electrolyte is supplied.

A process for the solvent extraction of a hydrocarbon mixture effecting separation of the mixture into a raffinate product of reduced aromaticity and an extract product of increased aromaticity comprises contacting the hydrocarbon mixture with a solvent comprising N- methyl-2-pyrrolidone in the presence of water in an amount of not more than 1À0 volume per cent in an extraction zone forming a raffinate phase comprising said raffinate product with a minor portion of solvent dissolved therein and an extract phase comprising solvent with extract product dissolved therein; separating the raffinate product from the raffinate phase and separating the extract product from the extract phase. The extract product may be separated from the solvent by extraction in a second zone with a second solvent selective for at least one constituent of the extract phase, e.g. water or a liquid hydrocarbon fraction boiling outside the boiling range of the hydrocarbon mixture and first solvent. The raffinate phase may also be separated into its components by extraction in a third zone with water.

In manufacturing a semi-conductor device comprising a semi-conductor body providing a plurality of circuit components, portions of a flat flexible metal foil are removed to provide a pattern of metal connections and joining portions holding the connections in place, the foil positioned in relation to the contacts of the body, the connections secured to the contacts and the joining portions removed. A patterned foil 3 is made from a flat flexible aluminium foil by providing a resist pattern on one side of the foil whilst leaving the central portion uncovered this portion being etched away to leave fingers 6. The foil 3 is placed over a semi-conductor body 1 being aligned with contacts 5 thereof using a microscope and bonded thereto using a laser, ultrasonics or multiple-head bonding machine. The foil and body are aligned over the pins 4 of a gold-plated header 2 with a gold foil therebetween, connections made to the pins 4 by spotwelding and the assembly heated at 410‹ C. to secure the body 1 to the header 2. The outer part of the foil 3 is removed along the line 7 using a hot wire cutter and the header secured in a can with a dry nitrogen atmosphere. The underside of the finger 6 may be provided with an insulating layer, e.g. by anodic oxidation. In another embodiment (Figs. 2 and 3, not shown) internal connections between various parts of the semi-conductor body are made using the patterned foil with subsequent removal of unwanted foil portions. In other embodiments two or more semi-conductor bodies are secured to the foil whilst connections are made to deposited contacts on a substrate rather than pins.

Title: Process for the purification and the decoloration of solutions containing colloidal impurities
IPC: C13B20/12
Filed: 1930-02-25
Abstract: Colloidal active charcoal is prepared in the state of a "sol," having an extreme fineness, maintained in its original moist state and utilized in the form of a paste having a water content of approximately 80-90 per cent, by finely pulverizing organic matters, hydrolyzing them with sulphuric or hydrochloric acid, preferably under pressure, until a complete or almost complete dissolution is obtained, after which the mass is heated first at atmospheric pressure and then under pressure of 3-5 atmospheres at a relatively low temperature (200-300 DEG  C.).  In an example, finely pulverized cellulose is added to a concentrated solution of zinc chloride, a little hydrochloric acid is added and the mixture is heated until excess water is evaporated. Subsequently the mass is heated under pressure to 200 DEG  C., cooled and freed from zinc chloride and acid.  If sulphuric acid is used for hydrolysing, a sulphate or bisulphate such as potassium bisulphate is dissolved in the sulphuric acid to retain the reacting mass in the liquid state.ALSO:Solutions containing colloidal impurities, particularly raw and intermediate products in the sugar industry are purified and decolorized by the use of a colloidal active charcoal in the state of a "sol," having an extreme fineness, maintained in its original moist state and utilized in the form of a paste having a water content of approximately 80-90 per cent.
