Filed: 1974-02-21
Abstract: 1467661 Peristatic pumps BELLCO SpA 21 Feb 1974 [21 Feb 1973 3 Aug 1973] 7975/74 Heading F1U [Also in Divisions A5 and H2]  A pumping unit for extra-corporcal haematic circulation comprises a pair of pumps of the peristaltic type 1, 2 which are driven alternately by a variable speed electric motor 30 via a transmission system incorporating a coupling for each pump by which one pump is driven whilst the other is stationary and vice versa. Each pump comprises a shaft 9, a bi-furcated member 8 and rollers 3, 4 which roll along and squeeze flexible tubes 5, 6. Transmission systems. In a first embodiment Fig. 1 the respective couplings 14, 33 are electromagnetically operated clutches, each comprising an annular member 15 connected to the pump casing and in corporating a solenoid 16, a plate 19 keyed to the pump's shaft and carrying a friction ring 22 and a disc 26 of ferromagnetic material which rotates with a pulley 23 but is also axially moveable to engage the ring 22 upon energizing the solenoid 16. Each pulley is connected to an associated pulley, by a belt 25 or 31, mounted on an output shaft of a speed reduction gear box 29 associated with the motor 30. In a second embodiment (not shown) a unidirectional coupling is mounted on each pump shaft and the output shaft of a speed reduction gear box associated with a reversible electric motor either drives each pump by a respective belt and pulley transmission or one of the uni-directional couplings is directly connected to this output shaft and the other coupling is driven either solely by a belt and pulley transmission or by a belt and pulleys together with a pair of meshing pinions. Finally in a third embodiment (not shown) the output shaft of a reversible motor carries a worm which meshes with two opposing worm gears, each mounted on respective shafts by way of a uni-directional coupling. These two shafts may either be the pumpshafts or are connected to the pumpshafts by way of respective belt and pulley transmissions. Control. In the first embodiment Fig. 1, a manual changeover switch is provided to alternately energize the couplings 14, 33 which can also be alternated by a switch controlled by a maximum and minimum pressure manometer in the associated haematic circuit. The speed of the motor 30 is continuously adjustable by a pair of potentiometers, one of which supplies a feed voltage to the motor when it drives pump 1 and the other feed a further voltage when the motor drives pump 2. The changeover from one feed voltage to the other occurs simultaneously with the changeover between couplings 14, 33. In the second and third embodiments the motor is reversed by a manual changeover switch on maximum and minimum pressure manometers.

Polymerization may be effected in the vapour phase but is preferably carried out by passing substantially anhydrous monomeric formaldehyde into a liquid hydrocarbon containing the carbonyl catalyst and agitating the liquid. Monomeric formaldehyde may be obtained from commercial paraformaldehyde, alpha-polyoxymethylene, formaldehyde solutions, and hemiformals, by pyrolysis. Specified carbonyls are of iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium and platinum. The carbonyl may be added to the polymerization mix dissolved in a solvent, e.g. ethyl ether. The hydrocarbon may be propane, butane, pentane, hexane, heptane, octane, nonane, decane, cyclohexane, decahydronaphthalene, benzene, toluene, or xylene. Other catalysts mentioned are triphenylphosphine, aliphatic amines and polymeric tertiary amines. The polymers may be made into films, fibres and filaments. Specification 753,299 is referred to.
