Abstract: Method and apparatus for apportionment includes compressing a paste in an apportioning chamber and thereafter delivering the paste towards a nipple after opening of a blocking element, the volume apportioning of the amount of paste to be distributed being undertaken by measuring the displacement of a piston in the apportioning chamber during delivery. The method and apparatus ensure that the apportioning chamber is placed under low pressure so as to facilitate introduction of the paste and delivery of the paste at a fast speed and then at a slow speed.

Abstract: A control system for controlling a direct current powered motor in which the direct current voltage, which may not be constant, is reversibly commutated across the coil or winding of the motor during the predetermined commutation time intervals and chopped at high frequency during each commutation time interval by a variable duty cycle, pulse width modulated voltage, in which the width of each voltage pulse, determined by a reference voltage, is varied as an inverse function of the magnitude of the direct current voltage which exists during each voltage pulse interval.

Abstract: A fluid dispenser with a fluid pump for dispensing fluid on movement of an actuator, and an air pump for delivering a stream of air through at least one sound generator on movement of the actuator. The sound generator produces at least two sounds as the actuator is moved from a first position to a second position, with each sound produced in a different time period during a cycle of operation, or differing from the other sound in respect of one or more detectable sound characteristics, such as duration, frequency, temporal alignment, amplitude, and/or timbre. The time period of each sound is a function of the relative location of the actuator between the first and second positions.
