Title: Method of and apparatus for monitoring an arc atmosphere
IPC: B23K9/16
Filed: 1975-12-29
Abstract: 1512850 Automatic control of concentration OSAKA DENKI CO Ltd 29 Dec 1975 [28 Dec 1974(4)] 53054/75 Heading G3R [Also in Divisions B3 and G1] In gas-shielded (with e.g. A, He) arc welding, particularly non-consumable (with filler wire) or, as shown, consumable electrode arc welding, the extent of the shielding function of the arc zone atmosphere is determined by measuring the proportion of nitrogen oxide in said atmosphere. The arc zone atmosphere may be influenced by gas nozzle spatter build up, gas nozzle/workpiece distance and angle, and workpiece shape and disposition, and by variation of gas flow. As shown, shielding gas is fed to the arc zone via a pipe 19, a gas flow adjuster 92 and a nozzle 18. The arc zone atmosphere is collected via a nozzle 27 by a pump 29 and supplied to a nitrogen oxide measuring device 23. In the latter, arc zone atmosphere is reacted, under reduced pressure, at 32 with ozone, from a generator 33, and a photo-electric device 34 detects, by way of an optical filter and multiplier, an infrared ray, radiated with a light emitting intensity proportional to mass flow-rate of NO, to provide an electric output signal which, amplified at 35, is fed to a differential amplifier 91, to be compared with a reference signal which may be set to represent the desired proportion of nitrogen oxide. The output from the differential amplifier may operate an alarm (e.g. buzzer) and may stop the welding power and wire feed device, and automatically controls the shielding gas flow adjuster 92 (e.g. valve). In Fig.9 (not shown), the arrangement is similar to that of Fig.8 but the measuring device output signal is fed to a differential amplifier the output of which acts to vary fume extraction flow, as by varying suction pump rotational speed. The above nitrogen oxide measuring device may be replaced by devices based on NO analysis methods including infrared ray gas analysis and ultraviolet light absorption comparison; NO 2 -proportion measuring methods including methods suitable for NO and constant potential electrolysis, NO + NO 2  analysis methods including naphthylethyldiamine (absorptiometric), constant potential electrolysis, ozone oxide heat analysis and oxygen oxidation; and total-nitrogen analysis methods including phenoldisulphonic acid (absorptiometric) and ozone oxidation-ion electrode.

Abstract: 1,223,499. Data processing. BURROUGHS CORP. 11 Nov., 1968 [4 Dec., 1967], No. 53384/68. Heading G4A. Stored - programme - controlled electronic accounting apparatus has a keyboard with alphabetic and numeric sections and means responsive to programme instructions to control or monitor information entry from the keyboard. An instruction counter driven by carry from a syllable counter accesses successive instruction words from memory, each word having four syllables which are selected in turn by the syllable counter for decoding to control the apparatus. An alphabetic or numeric keyboard entry instruction (syllable) enables the corresponding section of the keyboard, lights a lamp to indicate the section, and presets a key entry monitor counter. Successive characters entered are accepted if they are of the right type and the maximum number of alphabetic characters or the maximum numbers of numeric characters before and after the decimal point (this point is also entered by the operator) are not exceeded. If the type is wrong or the numbers are exceeded, an error indication is given and the operator may " backspace " the apparatus by means of a first reset key to permit the last character to be entered again correctly (if appropriate). The first reset key may be used repetitively to "backspace" " by more than one character, or a second reset key may be used and return the apparatus to the start of the execution of the current instruction. The monitor counter is decremented for each character accepted to indicate if the maximum numbers have been reached. A motor bar, if pressed, increments the syllable counter to select the next instruction.
Patent GB-539154-A (GB)
Abstract: 539,154. Melamine. SOC. OF CHEMICAL INDUSTRY IN BASLE. Feb. 28, 1940, No. 3697. Convention date, March 30, 1939. [Class 2 (iii)] Melamine is purified by heating the crude material in thin layers to a temperature above the melting point and removing the resulting smoke by means of a current of gas for collection in a suitable receiver. Preferably, the crude melamine is continuously brought on to a rotating electrically-heated plate maintained at a temperature between 350-450‹C. Thus, crude melamine is continuously supplied in a thin stream from a hopper A by means of a conveyer B and funnel C on to a plate D which is heated electrically to about 400‹C. and is rotated by a transmission K. The melamine melts and evolves a white micro-crystalline smoke which is removed by means of a current of air and is collected in the filter bag G having a receiver H at its lower end. The current of air is produced by maintaining a small under-pressure in the closed space J in which the filter bag is arranged. The residue on the plate, consisting chiefly of deamidation products such as melane, melene and mellon, is continuously removed by the scraper E. The melamine smoke may alternatively be removed by closing the apparatus on the charging side and operating with a small excess pressure of air or other gas such as nitrogen or hydrogen.
