Title: A process for the preparation of 2,6-dialkyl phenols
Filed: 1960-11-21
Abstract: A process for the preparation of a 2,6-di-alkyl phenol unsubstituted in the 4 position comprises mixing an aluminium halide catalyst with a phenol having a replaceable hydrogen atom on the ring carbon atoms in the para and at least one of the ortho positions relative to the hydroxyl group, at a temperature of at least 130 DEG C., mixing the resulting mixture with a molar excess of a mono-olefin, heating the mixture of phenol, mono-olefin and catalyst under pressure and separaing the 2,6-dialkyl phenol from the reaction mixture.  The product is preferably separated from the reaction mixture between the time at which the ratio of the molar concentration of the 2,6-dialkyl phenol to the sum of the molar concentrations of 2,6-dialkyl phenol, 4-alkyl phenol, 2,4-dialkyl phenol and 2,4,6-trialkyl phenol is a maximum and the time at which the concentration of the 2,6-dialkyl phenol in the reaction mixture is a maximum.  The preferred reactants are phenol itself or phenol substituted by alkyl, halogen, amino or nitro groups and alkenes containing up to 10 carbon atoms or aryl olefins.  The reaction is preferably carried out at 100 DEG C.-150 DEG C. in the absence of a molecular oxygen, water and iron and using a catalyst promotor, e.g. a halogen compound.  In the example phenol is alkylated with isobutylene in the presence of aluminium chloride and tert. butyl chloride as promotor using various temperatures for the catalyst addition and the alkylation.  Reference has been directed by the Comptroller to Specification 843,745.

Abstract: 1,182,228. Regulating; dual fuel engines. SEA BIRD (CLEAN AIR FUEL SYSTEMS) Ltd. Aug.21, 1968, No.39989/68. Heading F1B. In a dual fuel compression ignition engine, a valve 5 on the end of a liquid fuel injection pump control rod 3 controls the supply of gaseous fuel (or petrol) either directly or indirectly, the supply of gaseous fuel increasing as the supply of liquid fuel increases. In Fig. 1 gaseous fuel is fed through pipe 8 to a chamber 7a connected by pipe 9 to a Venturi in the air induction system and the valve 5 varies the suction in the chamber 7a, and hence the gaseous fuel supply, by controlling the admission of air from ports 10 into the chamber 7a. As the control rod 3 moves to the left to increase the liquid fuel supply from the injection pump, valve 5 closes an orifice in a plate 11 to increase the suction in chamber 7a and thereby increase the gaseous fuel supply. Plate 11 is free to move laterally so as to be self-centering. In Fig.5 the valve 56 on the pump control rod directly controls the supply of gaseous fuel flowing from pipe 60 to the pipe 50 leading to the induction system.

As shown, a U-section comprises side limbs 2 and 3 having spaced from the edges thereof tongues or ridges 4, 5 which are for engagement in corresponding grooves in the material constituting the panel. The tongues or ridges are arranged at different distances from the edges and they can be straight or corrugated.

The workpiece 10 (Fig. 3), is magnetically retained by the combined reinforcing flux of the magnets when the latter are oppositely polarized and released when they are similarly polarized so that their fluxes cancel. The first flux 11 due to magnet 3 is reinforced for retention by flux 12 of core 4 when the latter is permanently energized in the appropriate sense by a current pulse in the solenoid, and is counterbalanced by flux 12 of core 4 when a reverse current pulse demagnetizes it and remagnetizes it in the opposite direction. In a modification (Fig. 4, not shown) the polepiece having the underlying reversible permanent magnet is centrally interposed between two outer polepieces, and dual non- reversible permanent magnets are interposed in the gaps between the polepieces. In other modifications (Figs. 5, 6, not shown) the reversible and irreversible magnets are interposed between parallel ferromagnetic polepieces, or are alignedly interposed between a central polepiece and outer flanking polepieces, to present opposed working surfaces. In a preferred embodiment (Fig. 7) a magnetic holding device comprises a ferromagnetic base 8 to which alternate polepieces 6, 7 are anchored by screws 18, 19. Between the polepieces are disposed irreversible permanent magnets 3, and reversible permanent magnets underlying the alternate polepieces 6 are surrounded by solenoids 5 pulses by reversible D.C.
