Abstract
Abstract A counter system including a magnetically actuatable switch housed in a protective case. The case is secured to a frame supporting a rotatable mixing drum. A magnetic actuator is resiliently mounted on the drum and is moved past and close to the switch at each drum revolution. The switch is connected through an electrical circuit to a counter so that total revolutions of the drum are measured. A second counter system measures both total and mixing speed revolutions of the drum. In this second system one counter is actuable only if the drum is turning at a preselected speed. Two switches are used and they are connected to an electrical circuit which provides a signal to the mixing counter only if the drum is turning at mixing speed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
In combination with rotatable structure mounted on supporting frame means, the improvements for recording conditions with respect to said rotatable structure comprising: a. switch means mounted on said supporting frame means adjacent said rotatable structure, said switch means being encased in a shock and weather resistant housing, a tubular housing and fill material therein in which said switch means is embedded; b. at least one electrically operated counter for recording revolutions of said rotatable structure; c. nontiming circuit means connecting said switch means and said counter; and d. switch actuator means flexibly mounted on said rotatable structure for movement past and in close proximity to said switch means upon rotation of said rotatable structure, so that if said actuator means contacts said housing the actuator will flex and continue to move with said rotatable structure.
Claim 2
Dependent Claim
135 words
In combination with rotatable structure mounted on supporting frame means, the improvements for recording conditions with respect to said rotatable structure comprising: a. switch means mounted on said supporting frame means adjacent said rotatable structure, said switch means being encased in a shock and weather resistant housing, a tubular housing and fill material therein in which said switch means is embedded; b. at least one electrically operated counter for recording revolutions of said rotatable structure; c. nontiming circuit means connecting said switch means and said counter; and d. switch actuator means flexibly mounted on said rotatable structure for movement past and in close proximity to said switch means upon rotation of said rotatable structure, so that if said actuator means contacts said housing the actuator will flex and continue to move with said rotatable structure.
Claim 3
Dependent Claim
32 words
The combination according to claim 1, wherein said switch means is magnetically actuatable and wherein said switch actuator means includes a magnet secured to said flexible mounting for actuating said switch means.
Claim 4
Dependent Claim
16 words
The combination according to claim 2, wherein said switch means is a magnetically operated reed switch.
Claim 5
Dependent Claim
157 words
In combination with rotatable structure mounted on supporting frame means, the improvements for recording conditions with respect to said rotatable structure comprising: a. first and second switch means mounted on said supporting frame means adjacent said rotatable structure and being encased in shock and weather resistant housings; b. first electrically actuated means for counting total rotatable structure revolutions; c. second electrically actuated means for counting rotatable structure revolutions at preselected speeds within a predetermined speed range; d. at least one actuator means flexibly secured to said rotatable structure for movement past said first and second switch means and closely adjacent thereto for independent preselected time interval actuation of said switch means upon rotation of said rotatable structure; and e. circuit means electrically interposed between said first and second switch means and said first and second counting means, wherein said circuit means energized said second switch means upon movement of said rotatable structure within said predetermined speed range.
Claim 6
Dependent Claim
157 words
In combination with rotatable structure mounted on supporting frame means, the improvements for recording conditions with respect to said rotatable structure comprising: a. first and second switch means mounted on said supporting frame means adjacent said rotatable structure and being encased in shock and weather resistant housings; b. first electrically actuated means for counting total rotatable structure revolutions; c. second electrically actuated means for counting rotatable structure revolutions at preselected speeds within a predetermined speed range; d. at least one actuator means flexibly secured to said rotatable structure for movement past said first and second switch means and closely adjacent thereto for independent preselected time interval actuation of said switch means upon rotation of said rotatable structure; and e. circuit means electrically interposed between said first and second switch means and said first and second counting means, wherein said circuit means energized said second switch means upon movement of said rotatable structure within said predetermined speed range.
Claim 7
Dependent Claim
21 words
The combination according to claim 4, wherein said first and second switch means are in circumferentially spaced relation to one another.
Claim 8
Dependent Claim
22 words
The combination according to claim 5, wherein said second counting means is actuatable only above a preset voltage in said circuit means.
Claim 9
Dependent Claim
64 words
The combination according to claim 5, wherein said circuit means includes a capacitance and variable resistance, said capacitance being charged upon actuation of said first switch means and slowly discharged by said variable resistance, so that the time interval between actuation of said first switch means and said second switch means will determine the amount of voltage remaining to actuate said second counting means.
Claim 10
Dependent Claim
18 words
The combination according to claim 4, wherein said first and second switch means are magnetically operated reed switches.
Claim 11
Dependent Claim
21 words
The combination according to claim 4 and wherein said at least one actuator means is flexibly mounted on said rotatable structure.
Claim 12
Dependent Claim
23 words
The combination according to claim 9 and wherein there are two spaced-apart switch actuating means for actuating said first and second switch means.
Claim 13
Dependent Claim
25 words
The combination according to claim 10, wherein said first and second switch means are in close proximity to each other on said supporting frame means.
