SU133976A1 - Chronogram - Google Patents

Description

Instruments are known for recording and measuring directly in units of force (grams) the magnitude of the motor response in the study of higher nervous activity of a person, made in the form of a diaphragm mercury manometer with a recording device. Also known are electrical ergographs with a summing mechanism and recording indications on a conventional kymograph and electric chronoscopes.

The proposed chronoerograph differs from the known similar devices in that, in order to simultaneously register the health and determine the magnitude of the latent period and time of the conditioned reflex, it is made in the form of a chronoscope and ergograph combined into one design equipped with a contact device ensuring its automatic operation from a perforated tape. -job.

FIG. Figure 1 shows the mechanical layout of the instrument; in fig. 2 - his electrical circuit.

Chronogram consists of two main devices: finger ergograf and chronograph. A finger ergograph is adapted to work with weights or springs. The carriage / ergograph, by means of which the spring 2 is raised or the spring is compressed, is included in the chronograph electrical circuit. In order to determine the work performed, the ergograph 3 has a meter 3.

The chronograph consists of a signaling device, a zmoz belt with bellows with drums 4 and 5, moving contacts 6, a signal supply time marker 7 and a reaction time marker 8.

The perforated task tape 9, previously prepared using a special perforator, is pulled by a tape drum 4. When the holes on the task tape 9 hit the contacts 6, an electrical circuit closes through the drum 4 case and lasts 133976-2. one of the multi-colored light bulbs 11, 12, 13 (Fig. 2) and the timer 7 of the signal. In the case of a positive signal, the finger, the bend, is not examined, the carriage / ergograph is lifted with the help of a cable 14 and lifts the weight 2. At the same time, the self-supporting machine 15 of the carriage 1 draws an ergogram on a millimeter paper tape 16 driven by the engine 17 using a drum 5. Lentoprot The ergograph and chronograph mechanisms work synchronously. When the carriage moves, the protrusion 18 moves off and the contact 19 closes, thereby turning on the reaction time marker 8. A serrated rake 20 of the carriage actuates the curvimeter counter 3.

The device is designed to supply three light signals: two exciters, different in intensity, and one brake. At the request of the experimenter, one, two, and three signals can be reproduced in any sequence and possible combinations (desired stereotype). The duration of the signals and the intervals between the individual signals can vary within wide limits.

Subject invention

Chronogram; designed to register muscular performance in the study of human higher nervous activity, consisting of devices for working with weights and springs, an odometer-counter, a signaling device, a tape mechanism, two recorders, a timer and a perforator, characterized in that simultaneous registration of working capacity and determining the magnitude of the latent period and the time of the conditioned reflex, it is made in the form of a chronoscope and an ergograph combined into one design equipped with contact a device ensuring its automatic operation from a perforated tape-task.
