1. Apparatus for dispensing flowable material comprising:

  • holding means for holding a supply of flowable material;

    dispensing means for releasing an amount of flowable material from said holding means;

    first heating means for heating said flowable material in said hold means;

    second heating means for heating said dispensing means, said second heating means being in operative association with the first heating means such that the first heating means can be activated by the second heating means;

    unified control means for;

    (a) sensing the condition of the second heating means; and

    (b) sensing the condition of said flowable material in the holding means, wherein said unified control means coordinates the operation of the first and second heating means;

    such that the second heating means intermittently activates the first heating means in response to a preselected sensed condition of the flowable material of said holding means; and

    such that the first and second heating means are disabled in response to the sensing of a temperature at or below a preselected temperature of the second heating means.
