Title: Improvements in or relating to the dehydration of tetrahydropyran
IPC: C07D309/04
Filed: 1946-08-14
Abstract: Water is removed from tetrahydropyran/water mixtures by submitting the mixture to a distillation which is continued until the vapours therefrom give a condensate which, on cooling and standing, ceases to separate into two layers; tetrahydropyran being added to the mixture if the latter contains more water than the azeotrope, in an amount sufficient to ensure that, in a batch process, the proportion of tetrahydropyran in the still increases as the distillation proceeds, or that, in a continuous process, dry tetrahydropyran can be withdrawn continuously from the base of the distillation column.  In the example, 500 parts by weight of tetrahydropyran containing 15 parts of water were boiled in a still fitted with a fractionating column, condenser and decanter. The condensate was passed to the decanter and the top, tetrahydropyran-rich, layer which separated was returned to the top of the column.  Fifteen parts of the lower aqueous layer were collected at a still-head temperature of 71-75 DEG C.  The distillation was then continued at a reflux ratio of 5 : 1 and about 27 parts of a wet fraction removed at a temperature of 75-88 DEG  C.  The remainder of the tetrahydropyran was then distilled off in a dry condition.  The aqueous layer was submitted to redistillation and approximately 1 part of wet tetrahydropyran obtained.  This and the moist intermediate fraction may be recycled to the initial distillation process.  Specification 592,919 is referred to. p

Title: Purification of methyl isobutylcarbinol
IPC: C07C29/17
Filed: 1966-05-31
Abstract: Methyl-isobutyl carbinol containing mesityl oxide as impurity is purified by fractionally distilling the crude carbinol with introduction of water into the distillation system so that the mesityl oxide is distilled off.  Preferably the distillation is carried out in a fractionating column the impure carbinol being introduced near the top of the column and the water being introduced in the upper half of the column. Depending on the amount of water introduced in the column the carbinol obtained is either anhydrous or mixed with water.  In the latter case the carbinol may be dehydrated, e.g. by fractional distillation.  If desired the anhydrous carbinol obtained may be distilled to remove high-boiling impurities.

Abstract: 1,147,354. Circuit testing. GENERAL ELECTRIC CO. June 1, 1966 [June 3, 1965], No.24445/66. Heading G1U. [Also in Division H3] An arrangement for monitoring the condition of the circuit established by a subject 19 together with the leads 11, 12, 13 of an electro-cardiograph 10 connected thereto, e. g. for detecting failure in the leads, includes an oscillator 30 having a feedback circuit 20, the feedback circuit being required to have a predetermined impedance to enable the oscillator to operate to produce an output. The feedback circuit includes terminals to which are connected the leads being monitored, so that when the impedance of the test circuit changes, the feedback condition changes and the oscillator stops oscillating. The terminal connection of the leads, 11, 13 with the ECG 10 are connected via resistors to the feedback network, while lead 12 is connected to earth. The system is such that very little voltage is impressed on the subject by the test circuit, but to afford further protection, pairs of diodes 45, 46 are connected between the feedback circuit and earth. The output from the oscillator 30 is fed via a Darlington amplifier 47, 48 whose output, which is connected to a unijunction transistor 58, is normally low. When the oscillator stops oscillating, the input to the unijunction transistor rises, the transistor is actuated and an SCR 63 is fired. This operates a relay 65 to actuate warning indicators such as a flashing lamp and horn. Also the heart rate alarm circuits and pacemaker associated with the cardiograph are disabled.
