Title: Improvements in or relating to the production of niobium
Inventor: WILLIAMS ALBERT ETHERIDGE
IPC: C22B34/24
Filed: 1954-11-18
Abstract: 791,121. Producing niobium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 9, 1955 [Nov. 18, 1954], No. 33386/54. Class 82(1) Niobium is produced by reduction of potassium niobium fluoride by means of sodium which is used in a small excess, e.g. 10 per cent, of that stoichiometrically required. The reactants are heated in an inert atmosphere such as argon to bring about initiation of the reaction and the reaction products are maintained at a temperature above the boiling point of sodium to distil any excess of sodium and any potassium which has been formed. As shown, the reactants are contained in crucible 2 in which they are placed in alternate layers, each being rammed down before addition of the next layer. The crucible is contained in reactor vessel 5 which is surmounted by a cooled condenser 6 for collection of any distilled sodium and is connected through pipe 7, valves 10 and 11 to expansion chamber 13 and to tube 14 through which evacuation and charging with argon is effected. Electric furnace 1 is energized to heat the crucible to 420‹C. at which temperature the reaction commences. At the conclusion of reaction the temperature is raised to 1100‹C. to distil off any sodium remaining. The reactor is allowed to cool to 600-700‹C., valves 10 and 11 are closed and the connection between them broken and the reactor is removed and cooled to room temperature in air. The products of reaction are removed, crushed and leached two or more times in water, the first leaching being carried out in a short period, e.g. 3 minutes, to minimize loss of niobium as niobate. The niobium may be then washed with de-mineralized water and dried.

Title: Apparatus for processing photographic film or strip material
IPC: G03B17/00
Filed: 1975-08-12
Abstract: 1512103 Cutting film strip CX CORP 12 Aug 1975 [6 Feb 1975] 33560/75 Headings G2A and G2E [Also in Division B8] Apparatus for operating on film or like strip includes means for advancing the strip in either longitudinal direction, means for processing the strip at a station to which areas are successively advanced, the strip having locating apertures with leading and trailing edges along the length of the strip, either the leading or the trailing edges being subject to damage, an edge detector producing signals derived from the leading and trailing edges, means to suppress signals derived from edges subject to damage, and means to actuate the processing means in response to the remaining unsuppressed signals. Photographic film has rectangular holes evenly spaced along one margin, and the holes are engaged sequentially, when the film is used in a camera, by a detent to stop film winding when a new area of film is in position for exposure. The detent is not removed until the shutter has been operated. If undue force is used to wind the film while the detent is in position, the edge of the hole may be torn. After exposure the film is removed from the camera and spliced to other similar films and fed to a cutter 10, or a printer, marker, or notcher. The edges of the holes are sensed photo-electrically by a light source 22 and sensor 28. Light passes through a fibre optic 26, and is reflected from the film along a fibre optic 28 to sensor 24, which produces an electrical signal when either edge of a hole passes. The film is advanced, say 1/64 in. at a time, by a stepping motor 16, which drives a roller 14 pressed into frictional contact with the film by pressure roller 18. When a signal from sensor 24 is received by an actuation circuit 62, motor 16 starts again. Pulses from sensor 24 are fed through a delay gate 32 to a logic circuit, which may be alternatively connected, by operation of a switch 38, to deal with pulses generated by either the leading or the trailing edges of the holes. This circuit, together with delay gate 32, suppresses signals due to the damaged edges.

Abstract: 670,010. Code telegraphy. GENERAL ELECTRIC CO., Ltd., and BRYDEN, J. E. Dec. 30, 1949 [Dec. 31, 1948], No. 33667/48. Drawings to Specification. Class 40 (iii). [Also in Group XL (c)] Two oscillations of different frequencies, transmitted alternately, e.g. denoting marks and spaces in a telegraph receiving system, are respectively passed through two filters following a demodulator to two limiters or variable gain amplifiers having a common grid/cathode circuit comprising a resistor and capacitor in parallel, so that the receipt of oscillations by one limiter or variable gain amplifier, by grid current flow, reduces the gain of the other stage or renders it non-conducting. Noise due to ring- ing in a previously energized filter after switching to the other channel is therefore avoided. The arrangement may be applied to a diplex time-sharing system employing oscillations of different frequencies.

Title: Process for the cooling of alkali metal hydroxide solutions
IPC: C01D1/42
Filed: 1958-10-27
Abstract: Alkali metal hydroxide solutions are cooled by contact with a positive electrically charged heat transfer surface for removal of heat from the solution.  The electrically charged surface is formed by connecting the negative terminal of a direct current supply of 1 to 10 volts and 1 to 70 amperes to an electrode immersed in the solution and connecting the other positive terminal to the heat transfer surface.  The current density employed in the process is from 0.05 to 2.0 amperes/sq.ft. of heat transfer surface.  Alkali metal hydroxide solutions, e.g. sodium hydroxide, containing from 25-75% wt. of alkali metal hydroxide and which may also contain other salts, e.g. NaCl, NaHCO3 or Na2SO4 in proportion of at least 1% wt. usually 5 to 25% wt. are cooled from temperatures of 150-250 DEG F. to 70-100 DEG F. by contact with the heat transfer surface which may be the surface of a coil containing circulating coolant and made of nickel or nickel alloy to prevent corrosion.  The use of a plurality of series connected coolers is also referred to in which solutions are cooled by a counter-current stream of water passing through the series connected cooling coils of the coolers.  Each cooler of the series preferably contains a charged heat transfer plate but use is also made of a series of coolers in which only the first one or few coolers has a charged surface.  In an example, an alkali metal hydroxide solution at 200-250 DEG F. is cooled by passage through a plurality of series connected coolers in which the first or first and second coolers only contain charged heat transfer surfaces and in which the solution is cooled to about 170 DEG C., the uncharged heat transfer surfaces of the remaining coolers reducing the temperature finally to 70 to 100 DEG F.
