Title: Preparation of 3:3', 5:5'-tetraalkyldiphenoquinones
IPC: C07C46/06
Filed: 1957-10-17
Abstract: 3:31:5:51 - Tetra - alkyldiphenoquinones are prepared by treating, in a substantially homogeneous liquid system, a 4-halo-2:6-dialkyl phenol with at least an equimolar amount of a basic compound having a dissociation constant of at least 1.6 x 10-3 at 25 DEG  C.  The halogen atom on the ring is one having an atomic weight of at least 30 and preferably at least one of the substituent alkyl groups has a branched chain at the a  carbon atom.  In a preferred process the 4-halo-2 : 6 dialkyl phenol is formed in situ by treating a 2 : 6-dialkyl phenol with elementary halogen.  The preferred phenols are those where all the alkyl groups are secondary or tertiary and each containing up to about 12 carbon atoms.  The basic compound may be any strong organic or inorganic base, for example guanidine, piperidine, tetramethyl ammonium hydroxide, tetraethyl ammonium hydroxide, alkali metal alcoholates or alkali metal hydroxides.  When an aqueous inorganic base, e.g. aqueous sodium hydroxide, is used an inert organic solvent may be added to maintain the homogeneity of the reaction mixture.  Examples of suitable solvents are alcohols, particularly lower monohydric alcohols, dioxane, tetrahydrofuran, acetone, methyl ethyl ketone, dibutyl ketone, ethylene glycol dibutyl ether, diethylene glycol dibutyl ether or diethylene glycol diethyl ether.  The glycol ethers are particularly suitable as they readily dissolve the reactants but do not readily dissolve the substituted diphenoquinones.  When an organic base of strength similar to that of piperidine is used the oxidation-coupling reaction may be accelerated by heating the reactants and high boiling solvents such as liquid hydrocarbons with b.p. above 150 DEG  C., nitrobenzene, o-dichlorbenzene, diethylene glycol diethyl ether or dibutyl ether, stearyl alcohol or cetyl alcohol may be used.  When strong organic bases are used addition of further solvent is often unnecessary. When strong bases e.g. sodium hydroxide, are used the reaction temperature may be in the range 0-110 DEG C.; when weaker bases, e.g. of piperidine, are used higher temperatures, e.g. 60-200 DEG C., are required.  In the examples 3 :31 : 5 : 51 - tetra - tert. butyl diphenoquinone is prepared by (1) refluxing 4-bromo-2 : 6-ditert. butyl phenol with aqueous sodium hydroxide in dioxane; (2) refluxing 4-chloro-2 : 6-di-tert. butyl phenol with piperidine in nitrobenzene; (3) refluxing 4-chloro-2 : 6-di-tert. butyl phenol with sodium methoxide in methanol. Specifications 686,261 and 687,293 are referred to.

Title: Improvements in or relating to coin-freed mechanism for gas and like meters
IPC: G07F15/06
Filed: 1937-11-30
Abstract: 506,738. Prepayment mechanism for meters. CLOVER & CO., Ltd., T., and GLOVER, W. R. Nov. 30, 1937, No. 33050. [Glass 27] in a prepayment meter mechanism, a change-speed gear having slidable clutch members 15, 18, Fig. 2, is interposed between the meter drive and the ordinary prepayment mechanism, the clutch' members being actuated by a separate prepayment mechanism after the insertion therein of a coin of higher value, so that the amount of commodity passed by the meter, for the normal coin is increased, the separate prepayment mechanism remaining at the higher value until reset by hand. The quantity-mechanism is set forward in the usual way by a coin, e.g. a penny, inserted, through a price change disc 6, Fig. 1, and returned during consumption bv the meter drive shaft 1 on which is a sleeve 12 provided with a worm 2 meshing with a worm-wheel 3 on the prepayment mechanism. The shaft 1 is geared by wheels 10, 11 to a secondary shaft 9, the shafts 1, 9 having mounted thereon respectively rotatable but non-slidable clutch members 14, 17 geared together by wheels 13, 16 and slidable but non-rotatable clutch members 15, 18. The clutch member 14 is rigid with the sleeve 12. Normally for ordinary prepayment, the shaft 1 drives the sleeve 12 through the clutch members 14, 15, which are engaged, the shaft 9 and the clutch member 17 being driven idly through the gears 10, 11 and 13, 16 respectively. If consumption is desired with prepayment of a flat-rate for rent &c., a higher value coin, e.g. a two shilling piece, is inserted in the coin pocket 25 of the separate prepayment mechanism and the handle 30 thereof is turned. The coin lifts, against the action of a spring 39, a plate 36 in the pocket, a pin 37 projecting from the plate 36 being moved so that, when the pocket is rotated, it will engage a projection 44a, on a lever 44 and rock this lever. The lever is pivoted at 42 and has an arm 43 provided with a pin 49 to engage and rock a lever 45 having pins engaging the slidable clutch members 15, 18. The member 15. is thereby disengaged from and the member 18 engaged with its corresponding clutch member 14, 17, so that now the drive from the shaft 1 to the sleeve 12 is through the gears 10, 11, shaft 9, clutch 18, 17, and gears 16, 13. The lever 44 is held rocked by a nose 50a on a gravity controlled lever 50 engaging a shoulder 44d. A nose 44b acts as a stop for the projection 37 and prevents the coin pocket 25 from being returned to its initial position after the discharge of the higher value coin to a money-box 35a, positioned within the main money-box 35. When the collector withdraws the money-box 35, a cam plate 52 thereon engages a nose 50b of the lever 50 and rocks this to release the lever 44 allowing it, the lever 43 and clutch members 15, 18 to return to normal position ready for the insertion of a fresh higher value coin.
