Abstract

1,145,483. Piston burette. LABORTECHNIK ILMENAU VEB. 18 March, 1966, No. 12005/66. Heading B1X. A piston burette which may be driven either manually or 'by motor 1 by means of shaft 6 comprises at least one pair of piston and cylinder units with cylinders 7, 8 of equal volume, pistons 9, 10 being connected to shaft 6 so that when the shaft rotates the pistons move in opposite directions to one another, valve means 29, 30 associated with each cylinder for flow of fluid out of and into the cylinder, mechanism 35 coupled to drive shaft 6 for indicating the total change in fluid volume in each cylinder, and adjustable to allow for the use of other pairs of cylinders of different volume, means controlling the rate of rotation of shaft 6 to give a desired rate of feed, and means comprising for example one or more magnets 32 carried by stepping wheel 31 mounted on shaft 6, and making contact with element or elements 33, and an associated stepping mechanism (not shown) to enable division of the piston movement corresponding to one complete rotation of shaft 6 into smaller units. Cylinders 7, 8 may be hollow-walled and the annular space may accommodate a heating element (39). The pistons may also be hollow or have double walls (Fig. 2 not shown).
