Abstract: A control apparatus for controlling the generators of a multiple steam generator or multiple hot water generator installation. The control apparatus includes burner command apparatus which limits each of the generators to one of at least two different maximum firing rate levels. The command apparatus is controlled by a data storage device, such as a microcomputer, which periodically adjusts the maximum firing rate level of the generators in accordance with the predicted loads of the installation. The firing rate of the generators is controlled by modulating apparatus which varies the firing rate within the maximum firing rate levels in accordance with the actual measured installation load. By controlling the actual firing rate in response to both the predicted and the actual installation loads, efficiency of operation may be optimized.

Abstract: An internal combustion engine analyzer is described which permits analysis to be performed by attaching one sensor to the engine circuit. Timing at idle, engine speed, plug firing parade, etc., can be performed with only one sensor connected to the engine. For more extensive testing wherein additional leads are used, for example, at both the primary and secondary of the engine ignition coil, circuitry is provided for automatically triggering from both primary and secondary input signals or either one if only one is present. The analyzer also contains circuitry that enhances its use with both standard and electronic ignition systems. This circuitry rejects the noise generated by ignition systems in the cylinder ignition signals representative of plug firing so as not to mistrigger, or fire more than once for each plug firing.

Abstract: An improved operator controlled system for a copying machine to minimize user error and to provide a compact control console. An information display member is capable of sequentially displaying an identification of discrete operating features, such as number of copies, etc. A memory is capable of storing a predetermined set of first command signals for each discrete operating feature. A common set of control members permits the user to selectively generate second input command signals relative to any specific operating feature. These same control members are capable of inputing signals for a number of different operating features. The copying machine is capable of discriminating between the input command signals and the particular operating feature. The resulting operation of the copying machine would be in accordance with the predetermined standard set of machine functions or any combination thereof of operator inputed command functions.

Abstract: An automatically adjusted equalizer circuit includes an operational amplifier having a parallel resonant circuit, a voltage controlled resistor, and an amplifier output signal monitoring circuit in a feedback path for the adjustable equalizer. The presence of the parallel resonant circuit in the feedback path causes the amplifier gain to vary with frequency. An input signal to the operational amplifier will be distorted depending upon the particular loss characteristic of a telephone wire to which the input is connected. Automatic adjustment of the voltage controlled resistor, and the presence of the resonant circuit, causes the slope of the gain of the amplifier to inversely compensate for the loss characteristic of the particular line in question. Within the variety of lines, each line will have different loss characteristics as a function of length and gauge of the different telephone lines.
