摘要： A strip chart recorder has a chart dispenser, a platen, a writing table, and a chart advancing mechanism mounted in its base and a temperature-sensitive transducer having a bimetal coil mounted in its cover. The transducer is attached to a stylus that is mounted in the cover and marks the chart when the cover is closed as the chart that is being advanced across the platen. The cover includes a window and a lid for closing the window. The window is disposed over the writing table for enabling that portion of the chart that has been advanced over the writing table to be written upon after the cover has been closed. The cover is shaped for preventing access to the transducer and the marking means when the cover is closed with the window open. A detachable form is attached to the cover over the writing table and disposed in position for preventing closure of the lid prior to detachment of the form from the cover. The chart dispenser includes a chart chamber having a wall including an opening through which a tightly rolled chart may be inserted laterally. The chamber is dimensioned to enable the diameter of the rolled chart to expand to such extent that the inserted chart cannot be laterally removed from the chart chamber through the wall opening. Operation of the chart advancing mechanism is inhibited when it is sensed that there is no chart in the chart dispenser. The chassis is shaped to permit easy insertion and removal of a battery. A gear train of the chart advancing mechanism is mounted on a platform having a tab to facilitate assembly by insertion in a slot in the base. The cover defines a slot for receiving a tab on the bimetal coil of the transducer and a recess for axially receiving the coil and an attachment frame to facilitate assembly and permit precalibration of the bimetal coil.

摘要： A strip-chart recorder, including a stepper motor for advancing a recording medium from a roll by a predetermined distance upon each step of the motor; and a recording duration controller coupled to the motor for controlling the frequency at which the motor is stepped. The recording duration controller includes a selector system for selectively varying the frequency at which the motor is stepped.The selector system includes a timing circuit having a given number of outputs for providing timing pulses at different predetermined frequencies at different respective outputs; a like number of frequency selection circuits, each including a switch for selecting one of the predetermined frequencies, and a latch for providing an enabling signal in response to the actuation of the switch; and a logic circuit coupled to the timing means and the frequency selection circuits for providing a control signal for stepping the motor at the predetermined frequency associated with the enabling signal provided by the frequency selection circuit that includes the actuated switch. The latch continues to provide the enabling signal until the latch is reset. The frequency selection circuits are interconnected for causing a given one of the frequency selection circuits to provide its enabling signal whenever none of the switches of any of the frequency selection circuits has been selectively actuated.

摘要： A portable strip chart recorder includes a programmable electronic drive circuit to drive an electric motor and a means for identifying the strip chart as having been recorded on a specific recorder, said strip chart incorporating graphic means of identifying the time interval programmed by the electronic drive circuit with points for identifying which specific time interval has been selected. The case of the recorder consisting of a base and a top having a self-locking hatch. The hatch in the top provides access for the operator to actuate electric switches which program the drive circuit to move the strip chart at a selected rate versus time. The surface over which the strip chart moves has an identifying number, or symbol, which can be reproduced on the chart by applying friction or heat. The hatch in the top of the case in self-locking and when closed operates an electric switch to close the battery-operated circuit.
