Abstract: C<sub>1</sub> to C<sub>3</sub> mono-carboxylic acids, including a substantial proportion of acetic acid, are produced by oxidising a paraffinic hydrocarbon feedstock with molecular oxygen at a temperature in the range 150 to 250°C and at an elevated pressure sufficient to maintain the reactants in the liquid phase in the presence as catalyst, of phosphoric acid and'or a phosphate of one or more metals of Groups I and II of the Periodic Table, in particular sodium or potassium. In an alternative embodiment of the invention a co-catalyst in the form of one or more metals of variable valency, particularly manganese, is incorporated in the reactants. The reaction products are recovered by distillation.

Abstract: A tape cassette includes an internal drive system which is engageable by a drive capstan of a tape cassette machine and which drives a recording tape of the cassette at a speed which is higher or lower than the speed at which the tape would be driven by the capstan alone. Where the tape speed is reduced, the playing time of the cassette is increased and the cassette is therefore less wasteful for speech recordings where a high tape speed is not necessary. The drive system can comprise a drive belt (34) which is driven by the capstan (20) and which passes around a pair of rollers (32 and 32'), the tape being driven by means of one of the rollers (32'). Alternatively, a rotatable member (such as a roller, a tubular sleeve or a gear) can be engaged by the capstan, and the tape is then driven by means of the rotatable member.

A reference signal generator (26) establishes an infinitely variable reference signal indicative of the desired temperature of the water in the container and a temperature sensor (30) senses the actual temperature of water in the container (12) and establishes a feedback signal indicative thereof. The control further includes a first comparator (34) responsive to the reference signal and the feedback signal for establishing an error signal indicative of the error between the desired temperature and the actual temperature of the water in the container. A periodic signal generator (40) is provided for establishing a periodic input signal and a second comparator (46) is responsive to the error signal and the periodic input signal and establishes a periodic output signal having on-time and off-time during each cycle. Switching means (58, 62) are provided responsive to the periodic output signal for energizing the first valve (18) during the on-time of the periodic output signal and energizing the second valve (22) during the off-time of the periodic output signal.
