Title: Increasing the speed and thoroughness and economy of ultrasonic and other non-destructive testing of materials for detecting flaws or variances therein
IPC: G01N29/26
Filed: 1963-09-04
Abstract: An ultrasonic flaw detection apparatus comprises a plurality of piezo-electric crystals such as I, II and III, disposed in spaced relationship to each other and relative to the surface of a material specimen, e.g. tube K, to be tested, means for moving said specimen lengthwise past the crystals, a flaw detection instrument adapted to transmit electrical pulses to the crystals and to receive flaw-revealing echoes from said crystals, and sequencing cyclical switching means connected between said crystals and the detection instrument in such a manner that each crystal is connected individually to the instrument in sequential and cyclically repeated order. By using a plurality of crystals instead of only one the necessity to rotate the specimen is removed, thus increasing the tube testing speed, and as the flaw detection instrument transmits to and receives from only one of the plurality of crystals at any given instant the ratio of " noise level " to the flaw signal is kept at a minimum. The crystals I, II and III are positioned around the circumference of the tube K at equal 120 degrees spacings and each is respectively connected to segments 1, 2 and 3 of switch S. The rotating blade 25 of switch S is connected to a flip-flop unit which forms part of the flaw detection instrument. The flaw detection instrument contains a synchronizer, working in conjunction with the flip-flop unit, which times the spacing of the pulses sent out over conductor T from generator 16 (whose output has been adjusted to match the natural frequency of the crystals), and also provides the receiver 18 with a time sense. The crystals are inclined away from the specimen radius so that the probing sound therefrom enters the specimen surface at an angle indicated by the dotted lines. The tube K is moved lengthwise past the crystals by means of rollers (Fig. 3a, not shown). The Specification describes arrangements of the crystals for testing solid cylindrical, solid and tubular multi-sided, and flat specimens.

Title: Apparatus for Maintaining Tension in a Flexible Element.
IPC: B66C13/12
Filed: 1966-12-05
Abstract: An apparatus for maintaining tension in a flexible conductor 28 extending between fixed and moving junction boxes comprises a carriage 36 movable along a path parallel to that of the movable junction box, a cylindrical casing 105 mounted on the carriage for rotation relative thereto, and supporting a drum 106 around which the conductor is wrapped, and sprockets 116, 117 for rotating the casing 105 in response to movement of the carriage 36 along the path. A pair of series connected spiral springs 122, 123 coupled between the carriage and the casing oppose rotation of the latter in one rotational direction and urge rotation of the casing in the other rotational direction. The carriage 36 is supported by pairs of rollers 84, 85 engaging two tracks 67, 68 running the length of said path. A pair of chains 138, 148 extending the length of the tracks 67, 68 and anchored at both ends, pass over the sprockets 116, 117 and under another pair of sprockets mounted on the carriage. As the carriage 36 is pulled in one direction by the conductor 28, the chains 138, 148 cause sprockets 116, 117 to rotate and wind up the springs 122, 123. Upon release of this conductor pull, the springs drive the sprockets against the chains to move the carriage thereby taking up slack in the conductor. The initial spring tension is adjustable via helical wheel 91. The flanged drum 160 around which the conductor 28 is wrapped, is freely rotatably mounted via rollers 151, 152 supported on the casing 105. Wires 163, 164 are laid along the path of the conductor 28 to relieve the excessive tension in the latter. A channel 59 supports the portion of the conductor extending between the carrier 36 and the fixed junction box. The drum 160 may be provided with partition flanged to accommodate a plurality of flexible elements. In a further embodiment, Fig. 12 (not shown), the chain and sprocket device is replaced by a rack and pinion device. In another embodiment, Fig. 13 (not shown), only one chain and sprocket mechanism is used to drive the carrier and this is positioned in a recess intermediate the length of the cylindrical casing. In another embodiment, Figs. 22, 23, 24 (not shown), the carrier is mounted from one side by V-grooved rollers engaging V-shaped rails. The chain and sprocket drive mechanism is positioned between the two vertically spaced rails. The spring motor of any of the aforesaid embodiments may be replaced by an electric, hydraulic or pneumatic motor.

Title: Vapour phase oxidation of hydroxy compounds
IPC: C07D233/34
Filed: 1969-05-06
Abstract: Carbonyl compounds are prepared by the vapour phase oxidation of corresponding hydroxy compounds by contacting at elevated temperature a gaseous mixture containing oxygen and the hydroxy compound with a catalyst containing as essential constituents one or more of Cu and Ag with P as a promoter. Au, As, Sb and/or Sn may also be present. The catalyst may be a mixture of particulate ingredients or may be an alloy, the surface of which may be oxidized prior to use. It may be supported. The oxygen may be introduced at more than one point along the reaction. A diluent gas may be present. The reaction product after removal of readily condensable products may be recycled. Examples oxidize ethylene glycol to glyoxal with some glycollic aldehyde, glycollic acid and formaldehyde, propylene - 1,2 - glycol to methylglyoxal and acetol, butene-2,3-diol to diacetyl and acetoin, and cyclohexan - 1,2 - diol to cyclohexan - 1,2- dione. Reference is also made to the oxidation of C 1-6 aliphatic alcohols, cyclohexanol and benzyl alcohol. In the oxidation of ethylene glycol to glyoxal, unreacted glycol may be removed by cooling the reaction gases to a temperature below the condensation point of ethylene glycol but above that of glyoxal. The glycol reacts with some of the glyoxal to give 2,3-dihydroxydioxan. After separating the condensed material, which may be recycled, an aqueous solution of glyoxal may be formed from the remaining reaction gases. Formaldehyde may be removed from this solution by purging with a gas at elevated temperature and acidic impurities, mainly glycollic acid, by treatment with a weakly basic anion exchange resin in the free base form. Glyoxal prepared as above may be reacted with urea to give 4, 5-dihydroxy-2-ketoimidazolidine. If formaldehyde is also present the 1- and 1,3 - methylol - 4,5 - dihydroxy - 2 - ketoimidazolidines are formed or if an alkanol is also present the 0-alkylmethylol compounds.
