Abstract: 795,457. Flaw detecting. SWITZER BROS., Inc. Dec. 9, 1955 [Sept. 21, 1955], No. 29421/57. Divided out of 795,451). Class 106 (2). [Also in Group XL (a)] A penetrant composition for locating flaws in test bodies comprises a flaw penetrating watermiscible liquid vehicle and a plurality of fluorescent dyes one of which has an emission peak in the visible light range and one or more of the other has an emission peak or peaks lying in the range of maximum absorption of light of the first dyes. The second dye or other dyes should be substantially non-absorptive and reflective in the emission ranges of the first dye or other dyes. This cascading relationship is obtained with such dyes as Rhodamines and Cumarins, specific examples being 4 N, butylamino 1, 8 naphthal N-butylimide; 4 methyl-7 diethyl amino-cumarin, Rhodamine base; 4 amino sulpho 1, 8 naphthal 4<SP>1</SP> methyl phenyl-imide; Uranine Yellow; Beta methyl umbelliferone; and Fluorescein in twin or triplet relationship. The preferred vehicle may use sulphonated castor oil, polyoxyethylene sorbitol monoleate in water, dodecyl benzine sodium, sulphonate in water with or without diethylene glycol, and the iso-octyl phenyl ether of polyethylene glycol. The fluorescent penetrants are applied to the test bodies by coating or immersion, the bodies being scrubbed or sprayed with water and the cracks developed with talc and viewed by light rich in ultra violet, but deficient in green and longer wavelengths. A filter may exclude light reflected by the test body. The methods are applicable to flaws in metal plastic, glass and porcelain.

Patent GB-893423-A (GB)
Title: Improvements in or relating to the removal of carbon dioxide from gaseous mixtures
IPC: B01D53/14
Filed: 1959-09-01
Abstract: <PICT:0893423/III/1> CO2 is recovered from gaseous mixtures containing it together with one or more other components including H2S, carbonyl sulphide, SO2, hydrocarbons, H2, N2, O2, moisture or air by absorption at super atmospheric pressure in a countercurrent stream of propylene carbonate, reduction of the pressure to flash off the CO2 and subsequent recycling of the lean carbonate solution for further CO2 absorption.  A gaseous mixture containing CO2 p  under a partial pressure of CO2 of between 40-600 p.s.i.a. and a temperature of 40 DEG -90 DEG F. enters the base of a packed or tray-filled absorption tower 11 through line 10 and flows in counter-current to a descending stream of propylene carbonate cycling in the system and entering the tower through line 12. Undissolved gases are vented through line 13 to a suitable receiver 14.  Rich carbonate solution containing absorbed CO2 leaves the base of the absorption tower through line 15 and passes either directly through line 16 valve 19 and line 171 to flash-off chamber 20 or indirectly through line 17 and cooler 18 which reverses the excess heat of solution.  Solution passing through valve 19, which may be a turbine, into chamber 20 undergoes controlled pressure reduction, usually to atmospheric pressure, to effect dissolution of absorbed CO2 which is vented through 21.  Lean carbonate solution may be recycled direct to the absorption tower by pump 22 through lines 23 and 12 or some or all may be subjected to gas stripping in tower 24 to remove final traces of absorbed CO2.  Tower 24 receives stripping gas, e.g. air or other inert gas, through line 27 usually at the rate of 1-4 SCF/gallon of carbonate solution, and vents stripping gas and desorbed CO2 through line 28, carbonate solution passing out through line 26 back to the absorption tower.  Tower the gaseous mixture contains moisture, the gas and absorption solution feed rates and absorption temperature and pressure are so controlled that the rich carbonate solution preferably does not contain more than 2% moisture.  The absorbed moisture is desorbed in the flash off chamber 20 and is vented in the CO2 stream. In a modification of the above process (not shown) wherein CO2 is removed from gases comprising hydrocarbons which normally cause problems by solution in the propylene carbonate, the rich carbonate solution is removed from the absorption zone of the tower and passed into a tower medium pressure flash-off chamber forming the bottom of the tower where the pressure is reduced to between that existing in the absorption zone and the vapour pressure of the CO2 in the rich carbonate solution at the temperature of operation.  Flash-off gas comprising mainly hydrocarbon is removed from the chamber and may be compressed and cooled and recycled to the absorption tower for recovery with the other undissolved gas or be used independently as a fuel.  The remaining partially regenerated solution is passed to the final flash-off chamber 20 as before.

Filed: 1956-10-02
Abstract: 812,085. Converting. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 2, 1956 [Oct. 5, 1955], No. 29990/56. Class 38 (2). High direct voltage is derived from a lowvoltage source such as battery 8 by smoothing by LC circuit 4, 5, 6 the output, rectified at 3 of a transistor oscillator 1 fed from source 8. To prevent capacitors 4, 5 from prohibiting the building up of oscillations when switch 7 is closed to energize the oscillator 1, switch 7 is so arranged that when it is open, capacitor 5 is charged by battery 8 through resistor 9. The voltage developed across capacitor 5 blocks rectifier 3 until it is exceeded by that produced by the oscillator. Resistor 9 has a sufficiently high value to draw negligible power from the source when switch 7 is closed. The doublepole switch 7 of Fig. 1 may be replaced by a single-pole two-way switch, Fig. 2 (not shown).

Abstract: 164,388. Marks, E. C. R., (Pratt & Whitney Co.). Dec. 3, 1919. Milling-cutters; backing-off lathes.-Backed-off milling cutters of non-rectilinear contour are finished in a backing-off lathe by a narrow-pointed tool which is fed laterally through a distance less than its width for each rotation of the cutter blank. The relation between the backing-off action and the rotation of the blank is varied in accordance either with the longitudinal inclination of the teeth by utilizing the longitudinal feed of the tool carriage, or in accordance with the undercutting of the teeth, or both. Fig. 23 shows the apparatus diagrammatically. The backing- off cam 45 driven by worm gearing 51 and bevelgearing 52 from a shaft 48 operates a slide 40 carried on the main cross slide 39; the alteration in phase of the reciprocation is produced by means of a cam-slot connection 60 between the driving- sleeve 56 and the mandrel 55 under the control of an arm 58 attached to the carriage 38. In the case of undercut teeth the backing-off action is retarded by arranging the bevel-wheel 52 to slide on its shaft in unison with the main slide 39 and those driven by the shaft 50 through longitudinal cam-slots (not shown). Fig. 18 shows diagrammatically an apparatus for cutting radial teeth, the backing-off action of the tool S being effected by a cam 20 and the tool held parallel to itself as it follows the former 18. The position of the cam 20 is adjusted as the carriage moves along by a helical keyway 24 in the cam-shaft corresponding to the helical form of the teeth. Specification 164,387 is referred to.
