Abstract
Abstract An improved gage in combination with an amplifier which will respond more rapidly to a change of signal in one direction than to a change of signal in the opposite direction and where the ratio of the response rate in one direction to the response rate in the other direction is adjustable.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
A gaging device for gaging a dimension of work to be checked while the latter is in motion, comprising, in combination, sensing means past which the work is moved, electrical means responsive to said sensing means for producing an electrical signal which varies in accordance with the dimension of the work as sensed by Said sensing means, readout means for displaying a reading which is indicative of the dimension of the work, said readout means being controlled by said electrical means, and amplifier means interposed between said electrical means and said readout means for receiving electrical signals from said electrical means and controlling the input to said readout means, said amplifier means having two response rates to electrical signals supplied thereto, there being one response rate to a signal change which indicates an increase in the dimension of the work and a second response rate to a signal change which indicates a decrease in the dimension of the work, said two response rates being substantially different from one another.
Claim 2
Dependent Claim
169 words
A gaging device for gaging a dimension of work to be checked while the latter is in motion, comprising, in combination, sensing means past which the work is moved, electrical means responsive to said sensing means for producing an electrical signal which varies in accordance with the dimension of the work as sensed by Said sensing means, readout means for displaying a reading which is indicative of the dimension of the work, said readout means being controlled by said electrical means, and amplifier means interposed between said electrical means and said readout means for receiving electrical signals from said electrical means and controlling the input to said readout means, said amplifier means having two response rates to electrical signals supplied thereto, there being one response rate to a signal change which indicates an increase in the dimension of the work and a second response rate to a signal change which indicates a decrease in the dimension of the work, said two response rates being substantially different from one another.
Claim 3
Dependent Claim
17 words
The device of claim 1 including means for varying at least one of the two response rates.
Claim 4
Dependent Claim
89 words
The device of claim 1 where the response rate to a signal change which indicates an increase in the dimension of the work is very slow in comparison to the response rate to a signal change which indicates a decrease in the dimension of the work whereby said device will tend to read a minimum dimension of the work while ignoring apparent increases in such dimension unless the increase occurs gradually or is maintained for a time sufficient for the slowest of the two response rates to respond thereto.
Claim 5
Dependent Claim
89 words
The device of claim 1 where the response rate to a signal change which indicates a decrease in the dimension of the work is very slow in comparison to the response rate to a signal change which indicates an increase in the dimension of the work whereby said device will tend to read a maximum dimension of the work while ignoring apparent decreases in such dimension unless the decrease occurs gradually or is maintained for a time sufficient for the slowest of the two response rates to respond thereto.
Claim 6
Dependent Claim
43 words
The device of claim 2 where said means for varying at least one of the two response rates permits adjustment of the ratio of the faster response rate to the slower response rate to a ratio factor of at least 100 to 1.
Claim 7
Dependent Claim
52 words
The device of claim 1 where said amplifier means includes a readout meter and where an electrical delay circuit is interposed prior to said readout meter for delaying a change in the meter reading in one direction while permitting a substantially more rapid change in the meter reading in the opposite direction.
Claim 8
Dependent Claim
90 words
The device of claim 6 where said delay circuit includes capacitor means which is charged when a signal is supplied to said meter and which is connected with said meter to temporarily delay change in a meter reading in one direction while permitting a more rapid change in the opposite direction, and means for adjusting the rate of discharge of said capacitor means in order to control the magnitude of said delay and thereby control the rate of response of said device to a signal change in said one direction.
Claim 9
Dependent Claim
19 words
The device of claim 7 including variable resistor means for controlling the rate of discharge of said capacitor means.
