Description

A device is proposed for measuring the areas and lengths of the diagrams of recording devices and for calculating the average ordinate of the diagram over them. A reel is driven from the reel with a diagram, which transmits the length of the diagram to the dial by means of a worm gear. The said roller is provided at the end with a number segment, which is pressed with a compression spring against another roller, carrying a counting drum at one end, and a vernier, at the other - a rev counter. This roller is placed in a rotating frame, the lever of which is intended for connection with a writing device of a recording device. FIG. 1 shows a schematic side view of a device for measuring areas and lengths of diagrams; FIG. 2 - its top view; FIG. 3 is a section along the line AB in FIG. 2. The specified device is arranged as follows. In plank 26, all the mechanisms of the chart area counter and the chart length counter are attached. The square meter of the diagrams has a rotatable vertical frame / 4 planimeter inside which the planimeter roller 22 is placed, has a counting drum 17 and a vernier 20 on the right side. On the left side of the roller 22 there is a 2J worm gear placed on the counter // speed numbers. The roller 22 is adjusted by the set screws 19. The planimeter frame 14 rotates on the axes 13 of the planimeter set screws or on the axes 5 of the frame set screws 14. The numeric segment is pressed tightly to the roller 22 by means of a pressure spring 8. The roller 27 of the segment / also has a worm gear, the worm to and the gear are matched so that the length of the chart is calculated, the length of the chart is measured in centimeters and is indicated by the arrow 2 fixed by a nut 2 on the dial J. 25, a splicer engaging on a notched tooth, on which the diagram is wound. The gear ratio is 1:10. A roller of a segment / worm, etc. is placed in a box that is fastened to the bar 25. The principle of operation of the device is as follows. The roller 27 of the segment 7 is rotated by means of a toothed wheel, which is engaged with the roller gear, on which the diagram is wound. The speed of the roller is 27 segments / is equal to the speed of the roller of the diagram. The segment /, rotating, tightly presses against the roller 22 of the area counter of the diagram and rotates it, at the same time rotating the counter drum / 7, the vernier 20 and the counter // number of revolutions. The frame / can be deflected to the right horn near its axis or set screws with the aid of the lever P, which has a slide and is intended for connection with a writing device of a chart recorder. During the operation of the recorder (boron domer, dynamometer, etc.), the writing device deviates, and therefore the lever 9, which in its turn deflects the frame M, is deflected, so that the roller 22 makes different angles of inclination relative to the segment /. When the axes are large 22 and the segments / are perpendicular, then, although the segment / is rotated, the rotation 22 does not transmit the rotation, since the segment / is in contact with the roller only at one point.

But when the roller 22 deviates, segment 1 rotates it, and the length of the arc of the rollers will be equal to the length of the arc of the point of the segment with which the roller 22 is in contact. The rev counter // with ten divisions shows the total number of revolutions of the counting drum 17. The latter is divided into one hundred parts, and the ten are signed with the numbers 1, 2, 3 ... 10, counting from the stroke signed by zero. The vernier 20 reads one thousand fractions of the total revolution of the counting drum / 7. Each full turn of the counting drum 17 is marked with a pointer / 2 on the dial, by moving it from one stroke to the next, since one division of the dial corresponds to one full turn of the counter. The zero stroke of the vernier 20 marks the tenth and hundredths of a complete revolution of the drum circumference, and the countdown on the vernier gives thousandths of the same drum circumference. Considering the thousandth part of the drum circumference per unit, it can be written that the full rotation of the dial corresponds to ten times the divisions (10 X XO X X100).

at the beginning of the work, four digits on the drum, two on the first | 5y and dial are written; at the end of the work, the second reading is recorded in the same order; then the first is subtracted from the second reading and the difference is divided by the indication indicated by arrow 2 on the dial, i.e. on the length of the chart. This gives the average ordinate of the diagram. The difference in readings gives the area of the diagram; Chart length — The length of the base of the chart area.

This device greatly accelerates the processing of diagrams, which are not always accurately and extremely slowly processed by a hand planometer. This device not only accelerates, but also refines the processing of diagrams.

The present invention.

An apparatus for measuring areas and lengths of diagrams, characterized in that a roller driven by a gear from a drum with a chart and by means of a gear / gear drives an arrow 2 indicating the dial B a length of a diagram, provided with a segment / pressed by a spring 8 to the roller 22, which has a counting drum 17 for counting the areas and a worm gear 23 to the rev counter, and located in the rotary axle 5.5 of the frame 14, the lever P of which is intended to be connected to a recording device of a recording device.
