Patent GB-886164-A (GB)
Title: Improvements in the production of epoxides
Filed: 1959-03-09
Abstract: Epoxides, produced by reaction of monoolefines with 7-12 carbon atoms with peracetic acid, are separated from the reaction mixture by distillation in the presence of an excess of olefine which is at least sufficient to form an azeotropic mixture with the acetic acid formed.  Preferably 25 to 100% excess of olefine is used.  The excess of olefine may be added before the epoxidation reaction, or after the reaction and prior to the distillation.  There may also be added an inert vehicle which boils above the boiling point of the epoxide, such as di-isopropylbenzene, diethylbenzene, or paraffin hydrocarbons before the distillation.  The distillation is preferably carried out at temperatures below 100 DEG C., especially between 60 DEG  and 80 DEG C., by appropriate reduction in pressure.  The rise in temperature during distillation may be compensated for by reducing the pressure in stages.  The first fraction is the diluent used in epoxidation, then the azeotrope of olefine and acetic acid.  The acetic acid may be washed out or extracted with water and the olefine re-used, for example directly returned to the distillation column when working continuously.  The last fraction is the pure epoxide.ALSO:Epoxides are produced by reaction of mono-olefines with 7 to 12 carbon atoms with peracetic acid and separation of the reaction mixture by distillation, wherein the distillation is carried out in the presence of an excess of olefine which is at least sufficient to form an azeotrope mixture with the acetic acid formed. Suitable olefines are heptene, n-octene, 2-ethylhexene, tripropylene, tetrapropylene, styrene, vinyl-cyclohexane, indene, 1-phenyl-1-propene, ethylcyclopentene and methylenecyclohexane. Mixtures of such olefines with one another or with saturated hydrocarbons may also be used.  The peracetic acid may be used with diluents such as acetone, methyl ethyl ketone, ethyl acetate or butyl acetate.  The epoxidation is preferably effected between 40 DEG C. and 50 DEG C.  It is preferable to use an excess of 25% to 100% of olefine.  The excess of olefine may be added after the reaction, if desired.  An inert diluent which boils above the boiling point of the epoxide, such as di-isopropylbenzene, diethyl benzene or paraffin hydrocarbons, may be added for the distillation.  The distillation is preferably effected at temperatures below 100 DEG C.

Title: Improvements in current regulator control arrangement for motor control systems
IPC: G05D3/14
Filed: 1966-02-24
Abstract: 1,130,591. Automatic current control. GENERAL ELECTRIC CO. Feb.24, 1966 [Feb.26, 1965], No. 8097/66. Heading G3R. [Also in Division H2]. A current regulator for a motor control system, e.g. of the type described in Specification 1, 073, 180, wherein motor current regulated at a given level by control of a voltage supply source 15 whose voltage limits are changed as a step function comprises means such as 50 or 55 responsive to the occurrence of an event for developing an open-loop signal; means 20 for summing said signal with a current-responsive signal derived from a feedback loop 35 to provide a feedback signal of preselected magnitude, and for comparing said feedback signal with a reference signal to derive an error signal of apreselected magnitude regardless of the magnitude of the motor current signal at the time of said event; and means for reducing the magnitude of said open loop signal at a controlled rate. The means 50 may be associated with the contactor controlling the step-function changes of the supply source 15, and the means 55 with a device responsive to wheel slip. Thus, if a large change in motor current is called for by a step-function change or by wheel slip for example, the open loop signal modifies the error signal applied to the source 15 so that the motor current builds up from one regulated value to another at a controlled rate, the motor current increasing as the open loop signal decreases. The rate at which the open loop signal decreases is determined by an R-C circuit associated with transistor circuitry, and a suitable arrangement is described with reference to Fig. 2 (not shown).
