Method and apparatus for temperature regulating and dispensing flowable material
First Claim
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.

Abstract
The present invention is an apparatus for dispensing flowable material which comprises a holding vessel for holding a supply of flowable material, a dispensing device for releasing an amount of flowable material from the holding vessel, a first heating element for heating the flowable material in the holding vessel, a second heating element, in operative association with the first heating element for heating the dispensing device such that the latter can be activated by the former, a unified control system for sensing the condition of the second heating element and of the flowable material in the holding vessel, and coordinating the operation of the first and second heating elements such that the second heating element intermittently activates the first heating element in response to a preselected sensed condition of the flowable composition, and such that the first and second heating element are disabled in response to a preselected sensed condition of the second heating element.

2. Apparatus for dispensing flowable material comprising:
-
holding means for holding a supply of flowable material;
dispensing means for releasing variable amounts of the flowable material from said holding means;first burner means for heating said flowable material in said holding means; second burner means for heating said dispensing means, said second burner means being in operative association with said first burner means such that the latter can be activated by the second burner means; unified control means for;
(a) sensing the temperature of the flowable material in the holding means; and
(b) regulating a supply of fuel to the first burner means such thati) in response to the sensing of a temperature below a preselected minimum, fuel is supplied to said first burner element such that the fuel can be ignited by flame emitted by the second burner element, and ii) in response to the sensing of a temperature at or above a preselected maximum, the supply of fuel to said first burner means is interrupted and the flame is extinguished. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 35)
