    摘要: A transmission apparatus includes a large number of selectable gear ratios. The transmission apparatus includes first and second primary gears mounted on rotatable shafts having offset axes of rotation. A plurality of pairs of secondary gears, each including first and second secondary gears, selectively engage the first and second primary gears. The first and second secondary gears of one of the pairs of secondary gears are selectively coupled together and engage the first and second primary gears to transmit power from a power source at a predetermined gear ratio to drive a load.

    摘要: Corrosion inhibited alcohol compositions can be prepared which are suitable for use as anti-freeze compositions in the cooling systems of internal combustion engines. The alcohol is selected from at least one of the group consisting of methanol, ethanol, propanol, ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol and glycerol. The corrosion inhibitor comprises an effective amount of a conventional corrosion inhibitor selected from the group consisting of the alkali metal carbonates, borax, the alkali metal dichromates, the alkali metal silicates, phosphorous acid, phosphoric acid, an alkali metal tungstate, benzotriazole, tolyltriazole, an alkali metal salt of benzoic or toluic acid, an alkali metal salt of a phenol, an alkanolamine and an organo-silicone compound in addition to an alkanolamine phosphate and a heterocyclic nitrogen-containing compound. The phosphate is the reaction product of an alkanolamine and phosphoric acid. The heterocyclic nitrogen-containing compound has the formula: ##STR1##
