Description

According to the invention, there is a device for determining iolproductiveness and sensitivity IIIMii o | ir; iH of which, the key 1 of the Gritsch scheme is device-like, ne (1me1c across the irides of ccmoi tissue.

The essence of the proposed device is the fact that in it as a smart Ojiraiia primer with an electric current, consisting of a light .1 p photocell with; Ilelevo11 diaf | ) agmus, ostaionlepous end pa on GN11ZhN01.O kraoboobraznogo crown and located on opposite sides of the fabric.

fl.i fng. 1 shows the layout of the device; na g |) pg. 2- electric circuit.

Device mounted on a rejection table / having a guide 2 for a movable bracket of a bracket 3. K) it can move on rollers 4 from one to the other edge of the test tissue 3.

At the ends of the bracket are ukrenlei, 1 are located the lg) azkie sides of tklnn-5 lighter b and photo camera zm 7 with a shaved diaphragm.

Photocell 7 and |) gadfly mn 8 is connected to an electronic b.yuk 9.

In view of the fact that the change in the photocurrent at k) nt |) ole of the keodnoric chios I and the tissue, nan | ime |: according to the degree of its banding, sravptel1, but “1” (1 m wide from one edge dg) flows another1 | sun) zniklet 1) 14 deviations), then L) n the total duration of measurement of the entire width of the fabric in 5 seconds. it turns out about 2-- 3 oscillations in 1 sec.

Such relatively slow oscillations of the photocurrent are not recorded by a conventional amplifier, used to amplify sound frequencies, therefore, the so-called amplifier of a constant current, the cocky amplifier, is used in all electronic cxeML devices regardless of their frequency over time.

Photocell 7 is connected to the load, a state of four identical resistances R, R, Ra, R, R, and is powered by an independent power source.

The load diagonal of photo-eleptic 7 includes an in-voltage “d” 1 lamna JO (GH9).

Since there are no potential differences on the apodes of the lamp 10, there is also no potential difference on the resistances R (, and RK. The potential difference is also absent. Therefore, the pointer / 4 and the self-registering recorder 15 connected to the output of the amplifier are at rest.

This situation is true for the case when the sensitive organomermep1, which is relative to the tissue when it is interleaved, lacks the heterogeneity of the tissue in terms of its degree of fullness (banding).

The resistance R "of the photocell load is shunted by a large capacitor Ci, while capacitor C has a small capacitance. As a result of this change in the photocurrent or the displacement of the sensitive organ, arising due to the presence of tissue heterogeneity in the degree of its fullness, the average point of the resistances RI and R is removed, relative to the average point of the resistances RJ and Ki, to negative

or a positive region (since k () pdenzato |) C | retains its charge, depending on the size of the tkapi strip with a large i.-1I mepigy, under the opi-sensitive, degree of completeness.

(Supposedly, a potential difference is applied to the input of the amplifier, which arises when there is a heterogeneity of the TCU according to the degree of its filling.

This circumstance causes a change in the output voltage, which (|) is indexed by the pointer 14 and the registrar / 5, reflecting the heterogeneity of the tissue and its degree of filling (;

The sensitivity adjustment of the device is made by a rheostat / 6 in the lamp circuit / 7 of the illuminator 6 according to the standard.

The recorder / 5 consists of a magnetoelectric device, on the movable system of which the pen 18, 11 of the tape-drive mechanism / V, P | P1 is fixed, which is activated by the movement of the bracket 3.

Subject invention

A device for determining tissue heterogeneity, the Hbiii sensory organ of which, included in the electrical circuit of the ycTpoii community, is mixed across the test tissue, characterized in that, in order to determine tissue inhomogeneity according to its sensitivity, a photovoltaic unit is used, consisting of from the illuminator and photocell with a slit diaphragm mounted on the ends of the movable bracket bracket and located on opposite sides of the fabric.
