Abstract: An improved character reading system that utilizes two separate read devices: a first read device and a second read device in combination with a random access memory for storing each character read by the first read device, a memory control circuit for writing each character into the random access memory, and a comparison logic circuit for comparing each character as read by the second read device with the corresponding character stored in the random access memory. The system also includes a time-out counter for indicating when the last character has been read and a comparison logic timing circuit for controlling the comparison logic and triggering the random access memory read control circuit so as to provide the corresponding character to the comparison logic.

Abstract: A method is described for determining and indicating the time mean of a measured quantity as a function of its period of operation. A signal is generated responsive to the exceeding of a predetermined pair of values or coordinates of mean and period of operation of the quantity being measured. The measured quantity is integrated, and an extinguishing quantity is superimposed on the measured quantity. The value of the extinguishing quantity as a function of the instantaneous value of the quantity being measured is chosen so that a uniform storage state of the integrator corresponds with the pairs of values of mean of the quantity being measured and its period of operation.

Abstract: A digital frequency generator for producing a pulse output at a specified frequency is disclosed. The circuit is designed to operate in either of two modes in order to obtain high accuracy over a wide range of frequency operation. In a first mode, the circuit merely acts as a frequency scaler producing an output when a counter overflows. In a second mode, a comparator is employed for deciding whether an additional clock pulse delay is necessary to obtain the required degree of accuracy.

Abstract: Apparatus for utilizing a logical, record oriented move instruction is disclosed. By utilizing separately maintained data field descriptors which define the attributes of the data, the move instruction is able to transfer a multitude of different data types. From a source operand the logical instruction transfers data field by field to the destination. At the time of transfer, the logical move instruction reformats the data to meet the destination's description. The move instruction is applicable both to removing data from a data file and to restoring data into the data file.

Abstract: Logs which are to be divided into standard length blocks are first measured and their total length is displayed visually on an electronic readout device. Based on this length measurement, an operator selects one of several standard lengths and causes the log to advance relative to a cutoff saw where it is then cut. Total length measurement is determined by presetting a counter with a count representing maximum possible log length, down counting the counter when the trailing edge is detected and stopping the count when the leading edge reaches a reference position. Movement of the log is obtained from a tachometer generator mounted to rotate with a conveyor drive and an electronic circuit converts the output of the tachometer generator into pulses each representing a predetermined and convenient unit of length measurement.

Abstract: An apparatus for counting and indicating the number of bowling games played in a bowling establishment having a plurality of lanes, each equipped with an automatic pinsetter. A count of eleven feedback counter provides a single output signal in response to eleven frame input signals each of which may be taken from the various automatic pinsetters each time a frame is played on any one of the lanes to convert frame signals to game signals. The output signal from the counter is then fed to a totalizer indicator which indicates the number of output pulses received as indicative of the number of games played in the bowling establishment.
