Title: Improvements in methods of preparing methyl ethers of aromatic hydroxy compounds
IPC: C07C45/64
Filed: 1948-01-12
Abstract: A methyl ether of an aromatic hydroxy compound is prepared by the addition of a methyl sulphate to a hot aqueous solution of an alkali metal or ammonium salt of the hydroxy compound, the rate of addition being such that the methyl sulphate does not exceed its solubility in the solution, and the methyl ether is removed from the reaction mixture as fast as it is formed.  Resorcinol, phenol and naphthol are mentioned as hydroxy-compounds.  The methyl sulphate is preferably dimethyl sulphate, but may be methyl hydrogen sulphate, or contain a metal or ammonium group as in sodium and ammonium methyl sulphates. The reaction temperature is preferably about 80 DEG  C., or such that the product is steamdistilled off as it is formed.  The concentration of the salt of the hydroxy compound should be fairly high, e.g. 12-23 per cent.  Strong agitation should be used, particularly with dimethyl sulphate, which should be introduced at the bottom of the reaction vessel.  By-product sodium sulphate may be used to saltout the methyl ether from the aqueous part of the steam distillate.  The process may be operated continuously.  In the examples, (1-3) anisole is prepared by treatment of sodium phenate with dimethyl sulphate or methyl hydrogen sulphate, and (4) veratraldehyde is prepared from the sodium salt of vanillin and dimethyl sulphate.

Abstract: PURPOSE:To protect an induction motor, when there is a non-rotating induction motor, by taking a difference between a value obtained by equally dividing an inverter output current into a plurality of groups and the value of current flowing through a group of induction motors. CONSTITUTION:A bearing current detecting section 12 compares one phase current of one induction motor, detected through a current sensor 11, with 1/4th, for example, of same phase inverter 3 current detected through a current sensor 4. The bearing current detecting section 12 isolates a circuit breaker 2 when the absolute vate of thus detected difference exceeds a predetermined level. When an induction motor 5 provided with the current sensor 11 can not rotate, current concentrates to the induction motor 5 and the output of the current sensor 11 exceeds over 1/4th of the output current from the inverter 3. Consequently, the circuit is interrupted and the induction motor 5 is protected. The induction motor associated with the current sensor 11 or a group of induc tion motors can also be protected in a similar manner.

Therefore, even if the toner accumulated in the temperature detecting member 9 is dragged and about to drop at the starting time of the fixing roller 1, it is collected by the cleaning member of the downstream side or the releasing agent applying member 8. The cleaning member on the upper part of the fixing roller 1 or the releasing agent applying member 8 is in a position where the heat of the fixing roller 1 rises, so that the cleaning member or the releasing agent applying member 8 is easily warmed, the accumulated toner easily sticks to the cleaning member of the releasing agent applying member 8, and is surely collected. Thus, the coating or the releasing agent to the surface of the fixing roller is uniformed, and the toner is prevented from dropping from the temperature detecting member and cleaning member.
