Title: A method of producing a synthesis gas for use in the production of ammonia
Inventor: HEIDL HELLMUT
IPC: C01B3/02
Filed: 1965-09-23
Abstract: A method of producing an ammonia synthesis gas, comprising the steps of gasifying a sulphur-containing solid or liquid hydrocarbonaceous fuel with oxygen and steam; purifying the crude gas by cooling it to a temperature below 0 DEG  C. and removing the condensed substances; washing out the sulphur compounds from the gas at - 10 DEG  to - 20 DEG  C. with xylene; heating the sulphur free gas to about 350 DEG C.; mixing the sulphur-free gas with steam; conducting the mixture for the conversion of carbon monoxide contained therein to carbon dioxide and hydrogen by reaction with steam through two immediately consecutive catalyst stages, of which the first operates with a catalyst comprising iron oxide, or oxides of molybdenum and nickel or cobalt, and which is effective at temperatures of about 400 DEG  C.; whereas the second stage is operated at 200 DEG  to 220 DEG  C. with a copper oxide catalyst; washing out a proportion of the methane and argon together with the carbon dioxide with xylene at a temperature below - 15 DEG  C., conducting the gas over a methane-forming nickel catalyst at 200 DEG  to 220 DEG  C. for the purpose of removing the final traces of carbon monoxide and carbon dioxide, mixing the hydrogen enriched gas with nitrogen in the proportion N2 : 3H2 either before or after the methane forming step, and compressing the mixture to the pressure required for ammonia synthesis to take place. Intermediately between the two immediately consecutive stages for the conversion of the carbon monoxide, the carbon dioxide that is formed is washed out of a branch stream of the gas in a high-pressure wash and the residual gas returned to the main stream.

Title: Improvements in or relating to elastic and bulked yarns
IPC: D02G3/32
Filed: 1964-10-06
Abstract: An elastic and bulky yarn is produced by twisting at least one twisted or untwisted strand of elastomeric filamentary material such as segmented polyurethane held under high tension e.g. sufficient to cause an extension of four times the original length, with or around at least one twisted or untwisted yarn formed of continuous, man-made e.g. polyamide or polyester, filaments and previously textured e.g. crimped in a stuffer box or by twisting or false-twisting and setting, and held under normal tension.  The release of tension allows the elastomeric strand(s) to contract and increase the bulk and covering power of the textured component(s).  In a woven or knitted fabric, one of the yarns may be used for each two or three other yarns, optionally formed from the same material as the textured yarn(s).

Title: Gas shielded arc welding
IPC: H05B7/02
Filed: 1959-12-01
Abstract: 917,665. Arc welding systems. UNION CARBIDE CORPORATION. Dec. 1, 1959 [Dec. 12, 1958], No. 40841/59. Class 38 (4). [Also in Group XXII] In an arc welding system in which a pilot arc is transferred from an auxiliary electrode to the work prior to striking of the main arc, a relay serves after the welding current is disconnected, to transfer the pilot arc back to the auxiliary electrode when the pilot arc voltage between the main electrode and the work reaches a predetermined value. The auxiliary electrode is the gas nozzle or a probe electrode carried by the torch. In a gas-shielded spot welding torch, pilot arc current between the main and auxiliary electrodes 23, 29, Fig. 2, respectively, energizes a relay 31 to open contact 41 in the welding current control circuit. When the gas nozzle serving as the auxiliary electrode 29 contacts the work 25 the pilot arc transfers to the work and relay 31 releases so that actuation of the trigger closes contact 39 and the weld is made. After the welding current is switched off the torch is withdrawn from the work 25. When the pilot arc voltage increases to a certain value relay 33 operates to open contact 37 so that the pilot arc is transferred to the gas nozzle 29. In a modification, the voltage responsive relay 11, Fig. 1, is connected between the auxiliary electrode 9 and the main electrode 3. A resistance 15 in series with a contact 17 of the relay 11 decreases the potential -of the work 5 relative to the auxiliary electrode 9 after the welding current is disconnected.

Title: Improvements in and relating to writing instruments
IPC: B43K24/16
Filed: 1970-08-26
Abstract: 1,269,580. Reservoir pens. NIKKO PEN K.K. 26 Aug., 1970 [18 Sept., 1969], No. 40980/70. Heading B6P. In a writing instrument of the kind comprising two or more writing elements such as ball-point pen cartridges which can be selectively moved to writing position, repeated depression of an operating member such as push button 7 causes the writing elements to be projected in turn to the writing position. As applied to a writing instrument containing two ball-point pen units, the pens 4 are slidably mounted in diametrically opposite bores of a member 2 fixed in the barrel 1, 1a, and are retracted by springs 3. The upper end of each pen has a head 5 with a radial nib 5a extending outwardly through a groove 2b in the member 2. The upper ends of the nibs 5a bear against cam surfaces 6e ... 6h at the lower part of a member 6 rotatably mounted in the barrel. The upper part 6a of the member 6 is tubular with internal cam surfaces (6b, Fig. 3) engaged by a radial projection (7a, Fig. 2) on the spring-retracted push button 7 such that for each depression of the button the member 6 is rotated through 180 degrees. The cam surface 6e extends over 180 degrees and is joined by a notch 6f, 6g to a part 6h extending in the axial direction. A circular flange is actuated between the upper and lower parts of the member 6. With the parts situated as shown in Fig. 6 (Fig. 6B being a view from the rear of Fig. 6A) both pens are in retracted position. Upon rotation of the member 6 by depression of the button 7, the pen whose projection 5a engages the surface 6e is depressed until the projection is opposite the notch 6f, 6g whereupon, the projection enters the notch and the pen is held in projected position. If now the button is slightly depressed and released, the projection 5a moves out of the notch and the pen returns to retracted position since its projection is now situated in line with the cam part 6h, the other pen remaining in retracted position with its projection 5a engaging the flange on the member 6. If, however, the button is fully depressed, the first pen returns to retracted position but cam part 6e engages the second pen to move it to projected position. The arrangement may be adapted for an instrument containing three or more pens.

Title: Method and apparatus for controlling the cooling of a continu ously cast strand
IPC: G05D23/19
Filed: 1973-09-05
Abstract: 1448383 Continuous casting CONCAST AG 5 Sept 1973 [6 Sept 1972] 41871/73 Heading B3F [Also in Division G3] In a continuous casting process, in order to minimize cooling water requirements and optimize product quality, the history of cooling received by sections of the cast strand is taken into account by a computer which integrates the velocity of the strand as it moves through successive cooling zones and which correspondingly controls the amount of water fed to succeeding zones or parts or zones as the section passes therethrough so as to change the cooling zone's effective length and keep constant the residence time of each section in the total cooling zone. The set cooling time for the strand is adjusted in accordance with several parameters including the strand cross-section and composition, and the influences of oxide layer and vapour film formation. As shown, the computer 1 receives inputs 4 which sot the specific water requirement as a function of time and strand surface area (Fig. 2, not shown), the desired casting speed, strand surface temperature and other parameters. Inputs 6, 7 receive feedback information from sensors 21 and 22 of strand temperature and cooling water pressure, and a farther input 5 receives a signal of the actual strand speed, which is integrated and used to calculate the time spent by strand sections in the cooling zones. Computer outputs 35-38 are fed to controllers such as 10, 15, 18 which accordingly adjust the water supply valves to succeeding zones. Controller 10, via adjuster 11, controls the valve 25 for a whole cooling zone 28 and receives feedback information from a measuring device 12. Other cooling zones such as 32 are subdivided so that controllers 18 govern the water fed to small nozzle groups 31 via valves 27.

Title: Improvements in and relating to ultrasonic scanning cell
IPC: G02F1/33
Filed: 1965-10-08
Abstract: 1,127,238. Television; light deflectors. UNITED AIRCRAFT CORP. 8 Oct., 1965 [28 Oct., 1964], No. 42717/65. Heading H4F. A light beam 14, preferably a laser beam, is deflected by means of an ultrasonic deflection or scanning cell comprising a transducer 10 and a transparent medium 12, the transducer being actuated to establish a standing acoustical wave within the medium thereby producing a time varying density gradient and thus a time varying refractive index gradient within the medium normal to the direction of light propagation which causes the light beam to be deflected back and forth at the ultrasonic driving frequency. The curves T 1 -T 3  in Fig. 3, represent the acoustical pressure gradient within the cell, the portions of the curve to the right of the centre-line illustrating regions of higher density and those to the left regions of lower density. The magnitude of the angle of deflection of the light or laser beam is primarily determined by the wavelength of the sound wave, the index of refraction of the cell medium which is preferably a liquid, i.e. tetrachloroethylene, and the peak pressures. The cell medium may alternatively comprise crystalline quartz, water or luuite. As the light beam diameter is smaller than the sonic wavelength, the divergence or distortion of the light beam is not significantly affected and if it is directed through a pressure nodal plane of a sinusoidal standing wave the light beam deflection is sinusoidal. To obtain a more linear pressure gradient a triangular instead of a sinusoidal wave may be used, and to improve the performance of the cell a mosaic or segmented transducer is used. Cavitation of the cell liquid is inhibited by operating the cell under pressure, and fine tuning for adjusting the resonant frequency of the cell is achieved by increasing or decreasing this pressure, major tuning adjustments being accomplished by means of spacers and screws. By employing two deflection cells, one horizontal and the other vertical, Fig. 1, not shown, the cells being driven from the same ultrasonic power oscillator with a 90 degrees phase shift between them, a circular scan is generated. This scan may be made to spiral by amplitude modulating the driving power at a lower frequency than the ultrasonic frequency to provide a two-dimensional area coverage. An optical imaging system using this arrangement is described with reference to Fig. 5, not shown, in which the scattered radiation from a target area is received and used to modulate a cathoderay tube electron beam in accordance with the reflectivity of the target area.

Abstract: 1516658 Photometric gas analysis E I DU PONT DE NEMOURS & CO 17 Oct 1975 [17 Oct 1974] 42804/75 Heading G1A In a photometric method for determining NO x  concentrations, a known volume of a sample gas 15, Fig. 1 is mixed in a gas-tight cell 11 with an oxygen-containing gas 17 at controlled temperature and pressure to maintain a partial 02 pressure of at least two atmospheres, and the absorbance of radiation 22, and simultaneously the time derivative of the absorbance, are measured, 23, at a wavelength in the range 410-600 nm. Preferably the absorbance, indicative of NO 2  concentration, is combined with the square root of the time derivative, which is a function of the concentration of any NO which is undergoing conversion to NO 2 , the combination being indicative of the total NO x  concentration. Measurements are made 0À5-1À0 minute after the introduction of the oxygen-containing gas, to allow the apparatus to settle down. A photometer Fig. 2 comprises a light source 25 (e.g. Hg lamp) providing a beam 22 which is filtered, 26, to contain wavelengths in the range 410-600 nm. Part of the light emerging from the cell 11 is deflected by a partial mirror 27 into a measuring beam 30 and filtered at 35 to provide light, at a wavelength strongly absorbed by NO 2 , to a measuring photo-detector 36. Another part 28 is filtered at 29 to form a reference beam at a wavelength weakly absorbed by NO 2  but equally sensitive to other effects such as scattering by mist and dust in the cell 11. The difference between the outputs of logarithmic amplifiers 37, 33, responsive to detectors 36, 31 respectively, is applied to a control station 39 which includes differentiating and summing circuits (101, 105) Fig. 5, (not shown) and a recorder. The apparatus may first be zeroed by filling with clean air, and calibrated by measurements made on known gas samples.
