IPC: C25F3/12
Filed: 1956-06-19
Abstract: 834,821. Electrolytic jet-etching. PHILCO CORPORATION. June 19, 1956 [June 23, 1955; Jan. 17, 1956], No. 18921/56. Class 41. A method of treating a body of semi-conductive material by directing on to the said body a jet of liquid electrolyte carrying an electrical current which method includes maintaining a pressure gradient in the atmosphere region overlying the area of impingement of the liquid column of the electrolyte on the body in such a manner as to prevent the accumulation of electrolyte at said area which would otherwise form a coherent liquid body surrounding the end of the liquid column. The electrolyte may be such as to cause electroplating of the surface or such as to cause etching thereof. A jet of very fine diameter may be used. Aqueous or non-aqueous electrolytes may be used. Specified electrolytes are aqueous solutions of sodium nitrate, sodium chloride, potassium nitrate, sodium potassium sulphate or nitric acid. The workpiece may be of germanium. As shown, a workpiece 10 is positioned between opposing jets of electrolyte 19 and 20 issuing from nozzles 21 and 22, having apertures of extremely small diameter. Electric current is supplied to the jets and to the workpiece by means not shown. Suction nozzles 35 and 36 are positioned close to each side edge of the workpiece 10 for producing an area of reduced pressure in the region of the periphery of the areas of impingement of jets 19 and 20 upon the workpiece. The low-pressure area causes a flow of air in a direction generally parallel to the jets and then across the faces of the workpiece 10 carrying a smooth thin flow of electrolyte across the faces of the workpiece and into nozzles 35 and 36. Electromagnetic waves may be transmitted during etching through that surface portion of the semi-conductor body which is being etched and the waves may be used for measuring the remaining thickness of the body at the part being etched, in the manner disclosed in Specification 817,953. Specifications 814,364 and 824,484 also are referred to.

July 2, 1931, No. 19041. Convention date, Feb. 11. [Class 125 (ii).] In an apparatus for vacuumizing and sealing cans, the cans are first passed through a chamber 19 with the covers loosely attached, and thence to the sealing chamber 2, both chambers being under vacuum, but the higher degree of vacuum being maintained in the chamber 19. The cans are fed to the machine on a conveyer 11 through a rotary-valve 12 to the chamber 19, and they pass on a conveyer 17 therein into pockets 7 in a rotary valve 6, which in turn delivers them to the sealing chamber 2 whence they are delivered in a sealed condition to a conveyer 25. The sealing chamber 2 may alternatively be filled with inert gas, such as CO2. In sealing powdered substances the degree of vacuum is greater in the chamber 19 so that in the sealing chamber 2 the tendency is for air to enter the cans and prevent clogging the machinery with powder.
