Abstract
Abstract An alarm for a milk cooler which sounds when the temperature of milk within the cooler exceeds a predetermined value. A switch permits the device to be turned off to prevent it from sounding when milk is being discharged from the cooler or when the cooler is being cleaned with hot cleaning solvent. However when fresh milk is being introduced into the cooler that switch is overridden and the alarm sounds should the milk not be cooled to the required temperature after a predetermined interval of time.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A temperature warning device for use in conjunction with a milking machine and a cooler in which the milking machine causes milk to flow from one or more cows to the cooler where the temperature of the milk is cooled to a predetermined value, said warning device comprising: temperature sensor means responsive to the temperature of milk within the cooler; alarm means activated by said sensor means when the temperature of the milk within the cooler is above a predetermined value; means for selectively deactivating said alarm means; and warning means responsive to activation of said milking machine and to de-activation of said alarm means for warning of de-activation of said alarm means.
Claim 2
Dependent Claim
113 words
A temperature warning device for use in conjunction with a milking machine and a cooler in which the milking machine causes milk to flow from one or more cows to the cooler where the temperature of the milk is cooled to a predetermined value, said warning device comprising: temperature sensor means responsive to the temperature of milk within the cooler; alarm means activated by said sensor means when the temperature of the milk within the cooler is above a predetermined value; means for selectively deactivating said alarm means; and warning means responsive to activation of said milking machine and to de-activation of said alarm means for warning of de-activation of said alarm means.
Claim 3
Dependent Claim
118 words
A temperature warning device for use in conjunction with a milking machine and a cooler in which the milking machine causes milk to flow from one or more cows to the cooler where the temperature of the milk is cooled to a predetermined value, said warning device comprising: temperature sensor means responsive to the temperature of milk within the cooler; alarm means activated by said sensor means when the temperature of the milk within the cooler is above a predetermined value; means for selectively deactivating said alarm means; and overriding means responsive to activation of said milking machine and to de-activation of said alarm means for overriding said de-activation means and for causing said alarm means to activate.
Claim 4
Dependent Claim
118 words
A temperature warning device for use in conjunction with a milking machine and a cooler in which the milking machine causes milk to flow from one or more cows to the cooler where the temperature of the milk is cooled to a predetermined value, said warning device comprising: temperature sensor means responsive to the temperature of milk within the cooler; alarm means activated by said sensor means when the temperature of the milk within the cooler is above a predetermined value; means for selectively deactivating said alarm means; and overriding means responsive to activation of said milking machine and to de-activation of said alarm means for overriding said de-activation means and for causing said alarm means to activate.
Claim 5
Dependent Claim
109 words
A temperature warning device for use in conjunction with a milking machine and a cooler in which the milking machine causes milk to flow from one or more cows to the cooler where the temperature of the milk is cooled to a predetermined value, said warning device comprising: temperature sensor means responsive to by said sensor means when the temperature of the milk within the cooler is above a predetermined value; switch means for deactivating said alarm means; and switch overriding means responsive to activation of said milking machine and to de-activation of said alarm means for overriding said de-activation means and for causing said alarm means to activate.
Claim 6
Dependent Claim
109 words
A temperature warning device for use in conjunction with a milking machine and a cooler in which the milking machine causes milk to flow from one or more cows to the cooler where the temperature of the milk is cooled to a predetermined value, said warning device comprising: temperature sensor means responsive to by said sensor means when the temperature of the milk within the cooler is above a predetermined value; switch means for deactivating said alarm means; and switch overriding means responsive to activation of said milking machine and to de-activation of said alarm means for overriding said de-activation means and for causing said alarm means to activate.
Claim 7
Dependent Claim
37 words
The warning device as claimed in claim 1 further including time delay means for delaying the operation of said alarm means for a predetermined interval of time after said deactivating means is moved to an activating position.
Claim 8
Dependent Claim
46 words
The warning device as claimed in claim 1, further including an agitator for agitating the milk within the cooler; stop motion detecting means for detecting the stoppage of the agitator; and second alarm means activated by said stop motion detecting means upon de-activation of said agitator.
Claim 9
Dependent Claim
32 words
The warning device as claimed in claim 1, further including: third alarm means; and flow detecting means for detecting the flow of liquid from said cooler and for activating said third alarm.
