Patent GB-1120792-A (GB)
Title: System for recording information, e.g. a production monitoring system and sequencing control therefor
IPC: G07C3/10
Filed: 1965-08-23
Abstract: 1,120,792. Recording running-time and output of machines. WELTRRONIC CO. Aug.23, 1965 [Aug. 21, 1964], No.36118/65. Heading G1J. A system for recording information from a plurality of sets of sources e.g. separate work stations in a factory, in which the sets of sources are divided into families, comprises a memory for each family, a recording device for recording information in said memories, means coupling said recording device to the memory for one family to record information held in that memory and means for storing information from a set of sources of another family in the memory for that other family simultaneously with the operation of said recording device for said one family. A number of information sources supply information to a recording device in the form of a card punch. The information sources are multi-position tap switches or manually preset sources and solenoid actuated registers. These sources are grouped into sets at work stations in a factory and several sets form families or groups i.e. odd and even groups, each group having its associated memory 63, 64. As illustrated in Fig. 4 if an odd work station is subject to read-transfer; the driver applies a pulse train to the registers 61a through control 65a and contact TCR so that memory 63 is set by a signal through control 65b. Memory 63 then issues a signal through control 65e to emitter 66 which causes recorder 67 to operate. Information 61b which is set on tap switches is connected directly to the emitter subject to the control of odd-even selector 65f. The punched card produced at 67 is advanced to verifier 68 and if the card reads in accordance with the input signals from emitter 66 operation continues. With the verification of the card and the continuation of operation of the recorder, it issues a reset actuating signal on lead 70 to the driver. The sequencing of operations between odd and even groups is by a cam actuated contact on the punch card machine, as illustrated in Fig. 5 (not shown). In a first interval, the work station is selected, and the information at that station stored in the appropriate memory. In a second interval, said information is recorded while the registers for the opposite family are reset. The third interval may record the same information as was recorded in the second interval plus preset employee information. Following the verification of the last record made by a work station, the memory employed in that recording operation is reset to make it available for another work station of the group. This reset and final verification occur while the first recording operation for the next work station is accomplished.
