Title: Improvements in and relating to the production of phenols
Inventor: PRESTON ROBERT WILLIAM GUNN
Filed: 1955-07-06
Abstract: Phenols of formula <FORM:0786106/IV (a)/1> wherein X and Y are tertiary alkyl groups and R is an alkyl or substituted alkyl group (e.g. benzyl), are prepared by reacting a 3:5-di-tert.-alkyl-4-hydroxy-benzaldehyde with hydrogen peroxide, in the presence of an aqueous solution of an alkali metal hydroxide and a gas containing free oxygen to give a 2:6-di-tert.-alkyl-parabenzoquinone, reducing this to the corresponding hydroquinone and finally alkylating the hydroquinone. The molar ratio of hydrogen peroxide to hydroxy aldehyde is preferably at least 1:1 and the aqueous alkali metal hydroxide solution is preferably in a stoichiometric excess over the hydroxy-aldehyde.  The reduction may be effected catalytically using a copper catalyst or with reagents which liberate nascent hydrogen such as zinc and an acid.  The alkylation is carried out in known manner using, for example, an alkyl halide or dialkyl sulphate.  In an example, air was blown into a mixture of hydrogen peroxide, 3:5 - di - tert. - butyl - 4 - hydroxy-benzaldehyde and aqueous sodium hydroxide to give 2:6-di-tert.-butyl-parabenzoquinone which was reduced with zinc and acetic acid to 2:6-di-tert.-butyl-hydroquinone which was alkylated with dimethyl sulphate to give 2:6-di-tert.-butyl-4-methoxy-phenol.

[Class 38 (v)] Interlocked switches.-In a pedestal-type power switch provided with two circuitbreakers, either of which is positively moved with the power-switch member, the circuitbreaker which is in the switched-out position is arranged to effect the positive coupling of the other breaker with the power-switch member. In the application to duplicate bus-bar systems, either breaker may be actuated to select the bus-bars desired. The shank 22 of the movable power-switch contact 21 has an aperture 23 containing a ball 24 adapted to co-operate with either of two recesses 25, 26 in driving members 13, 14. The latter have projections 30, 31 for engaging and driving the contact 21 against spring- action 29, and have pins 17, 18 taking in slots 19, 20 in switch arms 7, 8, which are pivoted at 5, 6 and co-operate with contacts 9, 10. In the position shown, the driver 14 is locking the contact 21 to driver 13 and by raising the rod 15, the pin 17 rotates 7 anti-clockwise to the open position and at the same time contact 21 is raised. By lowering the rod 15 from this position into the position shown, switch 7 is reclosed and 21 lowered, and further downward movement of 15 closes 21, the straight part of slot 19 permitting this. In this position the rod 16 can be lowered to close switch 8, and then either rod 15, 16 can be raised to open switch 7 or 8, the associated driver 13 or 14 leaving the contact 21 coupled to the other driver, so that its switch cannot be opened without first opening contact 21. A pedestal-type insulator 1 supports the entire structure. In a modification (not shown), height is saved by operating the switches by means of pins on the breakers engaging cam grooves in two driver discs rotatable about a common spindle. The contact 21 is operated by a disc located between the driver discs, which serve as stop surfaces to a ball located in a recess in the centre disc. Alternatively the cams may be formed on the breakers and the pins on the drivers.

Abstract: 1,130,831. Electromagnetic forming of coils. GENERAL ELECTRIC CO. 2 May, 1967 [28 July, 1966], No. 20226/67. Heading B3A. method of developing wound -electrical coils in slots of a magnetic core, the coils being developed directly in theslots a coil winding . machine, comprises disposing the core 10 at a winding station 12; winding a predetermined length of wire 28 in the core slots; injecting at least one surge of electrical energy, into the turns to develop the turns into part of the wound coils; winding additional turns in the slots and injecting additional surges of energy therein until the coils are fully developed. The core 10 is held by means 14 and a reciprocating wire gun 24 winds the turns, the predetermined length of wire 28 being taken from an accumulator 30. The accumulator 30 comprises an insulated drum 80 on which is mounted a slip ring 88 for rotation therewith. A lead 92 connects an electrical-energy surge source 40 to the slip ring via a brush 90 and one end of the wire 28 is connected to a terminal 98 on the slip ring. A first length of wire is connected to a lug 106 and as the drum revolves, it.is drawn through an opening 104 from a supply and wound on to the portion 96 of the drum. At the same time the length of wire 28, previously wrapped on the portion 94, is withdrawn through an opening 108 and fed to the gun 24. This length of wire is connected to the source 40 by a lead 112. The drum 80 may be divided into as many portions as may be required to develop the wound coils. The insulation on the drum is thicker at each end than at the slip ring to maintain the inductance across the output terminals of the source 40 substantially constant, Fig. 5 (not shown). The gun 24 is driven by means 58 and when a number of turns have been wound it is withdrawn from the stator bore. A non-magnetic insulated cylinder 46 is inserted in the bore and a surge of electrical energy is passed through the wire 28. The resulting interaction of the magnetic fields produced in the turns and in the cylinder 46 by the eddy currents generated therein compact the turns in the stator slots. The process of winding loose turns and compacting them is continued until the coil is fully wound. In an alternative form, the cylinder 46 carries a winding, into which the surge of energy is injected and the slip ring 88 short circuits the wound turns so that a current surge is induced therein. The method of the invention is also applicable to armatures and other similar electromagnetic devices.
