Patent GB-816576-A (GB)
Title: Substituted tetrahydro-1,4-oxazine compounds
Inventor: SIEMER HARM
Filed: 1955-09-30
Abstract: Compounds of the formula <FORM:0816576/IV (b)/1> (wherein R is hydrogen, an alkyl radical of 1 to 5 carbon atoms or an aralkyl radical, R1 is aryl and R2 is alkyl), as free bases or as their acidaddition salts, are prepared by converting R1-alkyn-2-ols-(1) in methanolic solution containing BF3 and HgO as catalysts into intermediate addition products, splitting these products with acid to form R1-2-keto-alkanols-(1), converting these by reduction in the presence of ammonia, a monoalkylamine or a monoaralkylamine followed by reaction with ethylene chlorohydrin or ethylene oxide into R1-2-ethanolaminoalkanols-(1) or R1-2-(alkyl- or aralkyl-hydroxyethyl-amino)-alkanols-(1) and ring closing these with the splitting off of water.  In a modification of this process R1-2-ethanolamino-alkanols-(1) are produced directly from R1-2-ketoalkanols-(1) by reduction in the presence of amino-ethanol. The reduction in either case is preferably carried out by catalytic hydrogenation, for example with metals of Group 8 of the Periodic System, although electrolytic reduction is also referred to.  The cyclization stage may be carried out in the presence of a dehydrating agent such as sulphuric acid or zinc chloride.  The above process may be combined with the further step of alkylating or aralkylating N-unsubstituted products.  It is stated that the intermediate products referred to above are believed to be dioxan derivatives resulting from two molecules of the R1-alkyn-2-ols-(1).  In examples: (1) 1-phenyl-propyn-2-ol-(1) is stirred in methanol with BF3 and HgO to give 2 : 5-dimethyl - 2 : 5 - dimethoxy - 3 : 6 - diphenyl - 1 : 4-dioxan, this is boiled with aqueous methanolic hydrochloric acid to give 1-phenyl-2-keto-propanol-(1), this is hydrogenated in methanol in the presence of methylamine and Raney nickel at 80 DEG  C. and 100 atmospheres to give a methanolic solution of 1-phenyl-2-methylamino-propanol-(1), this solution is boiled with ethylene oxide to give 1-phenyl-2-(methylhydroxyethylamino)-propanol-(1) and this on heating to 100 DEG  C. with concentrated sulphuric acid gives, on working up, 2-phenyl-3 : 4-dimethyl-tetrahydro-1 : 4-oxazine; (2) a solution containing 1-phenyl-2-keto-propanol-(1), prepared as in Example (1), is hydrogenated in the presence of amino-ethanol and Raney nickel at 90 DEG  C. and 100 atmospheres to give 1-phenyl-2-(hydroxyethylamino)-propanol-(1) and this on heating to 95 DEG  C. with concentrated sulphuric acid gives, on working up, 2-phenyl-3-methyl-tetrahydro-1 : 4-oxazine; (3) the product of Example (2) is boiled with sodamide in toluene, ethyl bromide is added and the resulting mixture is heated under pressure at 150 DEG C. to give, on working up, 2 - phenyl - 3 - methyl - 4 - ethyl - tetrahydro - 1 : 4-oxazine.

Title: Improvements in and relating to the measurement of temperature
IPC: G01J5/28
Filed: 1936-10-15
Abstract: 483,312. Radiatioii pyrometers. GAMBRIDGE INSTRUMENT CO., Ltd., and MOSS, E. B. Oct. 15, 1936, No. 28003. [Class 40 (iii)] A method of measuring the temperature of a hot body consists in exposing known means for converting radiant energy into electrical energy to the radiation from the hot body for a short period of definite duration, and applying the total quantity of electrical energy thus obtained to. suitable indicating or recording device. In the apparatus shown, an image of the hot body is formed by a lens 1 on an energy converter or receiver 3, a shutter 2 being placed before the device 3, which is exposed for a definite period when the shutter is operated by a push-button 4. The shutter is wound up or set prior to each operation by means of a rod 5. A sighting telescope 22 is hinged at 23 and adjusted by a cam 24. The receiver 3 is connected as shown in Fig. 2 to a galvanometer 12 which is so constructed that it will remain deflected in accordance with a definite flow of current after the flow has ceased. Contacts 9, 10 are so operated by the shutter that 9 is open only when the shutter is open and 10 is closed when the shutter is set ready for use. Immediately after the shutter closes, the contact 9 closes a circuit through a small resistance. 11, and movement of the galvanometer is thus at once damped. At the next setting of the shutter, the contact 10 is closed and current flows from a battery 13. The small potential developed across the resistance 11, opposite to that from the cell 3, zeroizes the galvanometer pointer. Readings may be recorded by using a chopping- type galvanometer.

Filed: 1973-06-19
Abstract: 1471890 Ultrasonic thickness measurement BRITISH-STEEL CORP 14 June 1974 [19 June 1973]  29000/73 Heading G1G The thickness of an article is tested for deviations thereof from a nominal value by making several thickness measurements while scanning a measuring device over the article, combining the measurements into a composite value, comparing this with a desired range of value, and visually recording the comparison result as a symbol indicative of whether the composite value is greater or less than, or within the desired value range. For testing according to Fig. 2, the wall of a tube is helically scanned by one or more ultrasonic probes on a rotary carrier and the tube circumference is rotionally divided into twenty angular segments. The probe is pulsed at a rate to give thirty pulse-echo thickness measurements per segment at 25. The measurements are checked for validity at 26. Upper and lower tolerance limits for the measurement are set manually at 6 and 9. Whenever a valid measurement is made the limit values and the measurement value are entered in respective accumulators 8, 10 and 5. When all thirty measurements have been made for a segment and provided these have yielded a predetermined minimum number of valid measurements, comparators 11, 12 are enabled for comparison of the accumulator contents. Outputs on lines 15, 16, 17 indicate whether the thickness measurement, effectively averaged over the segment, is within, below or above tolerance respectively, and control pens of an electrostatic recorder so as to produce a square, -, or + sumbol respectively. Each symbol comprises a 5 x 5 dot matrix, details given. The recorder is synchronized with the probe scanning, details given, such that the symbols form a "map" of tube wall thickness variations. Indicator lamps, for monitoring system operation, are energized in response to the conditions "within tolerance", "above tolerance", "below tolerance" and "no valid result". The tube may be marked by paint markers according to the measurement results.
