Abstract
Abstract Apparatus for verifying the operation of mechanisms electrically controlled by operator keyboards which includes delayed electrical sensing of the activation of the mechanisms and alternate printing of data corresponding to the keyboard output signals and to the signals transduced from the operation of the mechanisms. In one version of the verifier the actuation sensing is performed by switches to set a storage means which is then read out after a predetermined delay from the time that data signals are received from the keyboard for storage or printing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
Verifier apparatus for a signal-controlled mechanism comprising: controllable actuation sensing means adapted to be physically coupled to moveable elements of the signal-controlled mechanism for developing sense signals indicative of actuation of the mechanism, a source of input control signals coupled to said mechanism, means coupled to the actuation-sensing means for storing the sense signals developed by it, sequence control means coupled to the signal storage means and responsive to the signal-controlled mechanism for subsequently initiating readout of the contents of the signal storage means, and data comparison means adapted to receive said input control signals and coupled to the data storage means for comparing the sensed data with the input control signals under control of the sequence control means.
Claim 2
Dependent Claim
119 words
Verifier apparatus for a signal-controlled mechanism comprising: controllable actuation sensing means adapted to be physically coupled to moveable elements of the signal-controlled mechanism for developing sense signals indicative of actuation of the mechanism, a source of input control signals coupled to said mechanism, means coupled to the actuation-sensing means for storing the sense signals developed by it, sequence control means coupled to the signal storage means and responsive to the signal-controlled mechanism for subsequently initiating readout of the contents of the signal storage means, and data comparison means adapted to receive said input control signals and coupled to the data storage means for comparing the sensed data with the input control signals under control of the sequence control means.
Claim 3
Dependent Claim
55 words
Verifier apparatus according to claim 1 wherein: said input control signal source includes a keyboard coupled to said mechanism, said mechanism includes means to disable the keyboard each cycle of operation, and the sequence control means is responsive to the disabling of the keyboard for synchronizing the verifier apparatus with the operation of the mechanism.
Claim 4
Dependent Claim
33 words
The verifier apparatus of claim 2 further comprising second data storage means for storing the keyboard data signals and transmitting them to the data comparison means under control of the sequence control means.
Claim 5
Dependent Claim
47 words
The verifier apparatus of claim 2 wherein the data comparison means comprises a multiplexer unit for receiving the keyboard data signals and the sense data signals under control of the sequence control means and mEans coupled to the multiplexer unit for printing the data received from it.
Claim 6
Dependent Claim
32 words
The verifier apparatus of claim 4 further comprising second data storage means for storing the keyboard data signals and transmitting them to the multiplexer unit under control of the sequence control means.
Claim 7
Dependent Claim
32 words
The verifier apparatus of claim 4 wherein the printing means is a digital column printer which alternately prints the keyboard data signals and the sense data signals received from the multiplexer unit.
Claim 8
Dependent Claim
39 words
The verifier apparatus of claim 6 wherein the actuation sensing means develops binary-coded decimal signals in response to actuation of the mechanism and the printing means comprises a plurality of column printer elements for printing different binary-coded decimal digits.
Claim 9
Dependent Claim
26 words
The verifier apparatus of claim 4 wherein the actuation-sensing means comprises a plurality of switch elements coupled to be responsive to the actuation of the mechanism.
Claim 10
Dependent Claim
29 words
The verifier apparatus of claim 8 wherein the switch elements are lever-operated electrical switches carried by a supporting bracket which latches to the signal-controlled mechanism without affecting its operation.
Claim 11
Dependent Claim
35 words
The verifier apparatus of claim 8 wherein each switch element has an actuating arm which rests free of the mechanism and is contacted by a moveable element of the mechanism only when it is actuated.
