Title: Process for the preparation of halogenated pyran compounds
Filed: 1945-07-11
Abstract: Compounds of the general formula <FORM:0598080/IV/1> wherein X represents chlorine or bromine and R is an aliphatic group, and substitution derivatives thereof, are prepared by reacting 2 : 3-dihydropyran, or substitution derivatives thereof, with bromine or chlorine or a compound which will yield halogen under the conditions of the reaction, e.g. tertiary butyl hypochlorite or bromonitromethane, and a monohydroxy compound of the general formula ROH, where R has the above significance, or the corresponding metal alcoholate in which case it is preferred to conduct the reaction in the presence of a solvent.  The reaction is preferably conducted in substantially anhydrous conditions, in the presence of a sufficient quantity of a basic substance to neutralize hydrogen halide formed and the temperature maintained below 100 DEG  C.  An organic solvent which is substantially inert to the action of chlorine and/or bromine and a pressure greater than atmospheric may be employed.  In examples: (1) 2-methoxy-3-chlorotetrahydropyran is prepared by reacting 2 : 3-dihydropyran, chlorine and methanol in the presence of calcium carbonate at a temperature below 10 DEG  C.; (2) similarly 5-chlor-2 : 3-dihydropyran is reacted in the presence of sodium carbonate to yield 2 - methoxy - 3 : 3 - dichlortetrahydropyran; (3) 2-methoxy-3-brom-3-carbmethoxytetrahydropyran is prepared by reacting methyl-2 : 3-dihydro-5-pyroate, bromine and methanol in the presence of calcium carbonate. 5-Methyl-2-methoxy-3-chlortetrahydropyran may also be prepared from 3-methyl-2 : 3-dihydropyran and methanol.

Patent GB-685326-A (GB)
Title: Improvements in or relating to process for making steel
IPC: C21C5/32
Filed: 1950-07-19
Abstract: In a process for making low phosphorus low nitrogen steel from pig irons of varying phosphorus content, molten pig iron, lime-containing slag-forming material in sufficient quantity to produce a slag having a lime/silica ratio of at least 1.5, and iron oxide are introduced into a basic-lined vesel and an oxidizing gas containing more than 21 per cent by volume of oxygen is blown in at the metal surface.  The turbulent mixing of slag, iron oxide, and metal produces rapid elimination of phosphorus and some of the carbon and the rapid solution of lime so that the lime/silica ratio is developed while the carbon content of the metal is above 1.0 per cent.  The carbon content of the metal is then reduced to the desired value by the continued injection of the oxidizing gas, substantially all the heat for the process being obtained by the exothermic reaction and the formation of the slag.  A lime/silica ratio of 2 may be developed while the carbon content of the metal is above 2.0 per cent.  The slag may be removed and replaced by a new slag at intermediate stages in the process particularly when the original pig-iron has a high phosphorus content.  Preheated lime and mill scale may be introduced into the vessel and then the molten pig-iron poured in. The oxidizing gas may be introduced through a lance and, if desired additional ground lime and mill scale may be added to the gas stream.  Good elimination of sulphur is also stated to be obtained.

Abstract: 932,902. Cutting variably groove-spaced gramophone records. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 11, 1962 [May 16, 1961], No. 18215/62. Drawings to Specification. Class 40 (2). In apparatus in which a pair of heads successively track a magnetic tape recording to control the drive to the stylus traversing means, groove-echo, due to recording a " loud " groove too closely on one or other side of a " soft groove is prevented by feeding the signals from both magnetic heads into means which measure the ratio of their relative strengths and control the groove spacing accordingly. For maximum effect, control is exercised only when the ratio exceeds 3 : 1, when the difference exceeds a given threshold value; the control signal is further fed through a weighting network to the traversing means which passes frequencies between 1 kc/s. and 3 kc/s. unattenuated, but attenuates higher and lower frequencies whose audible effects in respect of groove-echo are less significant.
