SU13265A1 - Device for determining the average weight of various objects by class weighting them - Google Patents

Description

Often, YABL is necessary to weigh a large number of individual objects in order to determine their average weight and mathematical characteristics of its change. / Usually, these individual weights are produced with great accuracy, are time consuming and require the participation of highly-skilled workers.

Meanwhile, in many cases, changes in the average weight are constructed according to laws close to the theoretical law of mass distribution, which is characterized by a number of symmetries about the arithmetic average J. It follows that definition. You can keep with sufficient accuracy not the exact individual values of individual variations, but the classes of the latter, and the class gap can be arbitrarily large for a correct row, if only the number of observations is sufficiently large.

With significant class intervals, there is no need for precise tools, and determining not the exact weight, but only the belonging of an object to one or another class, simplifies the observation technique without affecting the accuracy of their results.

To determine the average weight of various objects by class weighting them, the proposed device is intended, which is based on the fact that on the box in which weights are placed, the number of which is equal to the number of classes, and the difference in weights corresponds to the value of the class weight and the buttons , including electromagnetic meters, used to determine the number of objects to be blasted.

In FIG. 1 schematically depicts the proposed device; FIG. 2, 3 - its modifications; FIG. 4 is a detail of the device, but FIG. 3

Janschka A (fig. 1), instead of the usual weights, supply weights 1,2 ..., the difference between the weights of which is equal to the value of the selected class and the weight of the smallest weights 1, whose number of all weights equals the number of classes. On the same box, J., there are buttons a, b, .., designed to close the circuits of the system of parallel electromagnetic counters aj .... a2, serving to count the number of objects to be weighed, belonging to each given class, each with a counter attached to it, and corresponds to a certain class of weight.

If we place a weight equal to or closest to the minimum object weight on one of the ordinary scales and the other object itself, then the weighing operation. will be reduced to the retrieval of two adjacent weights, between the weights of which are the weight of the objects pressed to the corresponding button.

As a result of sequential weighing of the t & objects, the counters will punish a ready variational series that can be used for non-direct mathematical processing.

In the modification of the device shown in FIG. 2, the "1 a ......" trigger elements are automatically activated by double closure of the current source value. The first closure occurs through contact with the spring d when the corresponding weights are removed from the socket,: and the second through the contact with weights, as soon as the class weights are collected, in order of sequence, giving in total to the main weight Q equal to or greater than the weight of the object V. Takyi in the image of the counter a, switched on by the weight, will count repetition.

weights corresponding to the class gap between the weight of this weight and the nearest smaller one.

The modification shown in FIG. 3 and 4, consists of a balance arm E on unequal-arm weights on a prism D, a sia-transgenerate movable balance weights q JL F and a scutter H serving as the ball Q, which is moved by the fork W, but connected to the carriage t Sliding along the guide bar L The latter is made up of a series of conductive plates separated by insulating gaps of plates G, connected each by a conductor through a winding of a corresponding electromagnetic meter and one of the pov btary of the chVG. The carriage w (Fig. 4) is equipped with two SLIDING contacts s and 4, of which the first connects to the {) start of the carriage with one or the other plate r, and the second slides as the carriage moves along the copper plate c connected through the plate электром electrically electrically unplugged w with a different lolyuyami. battery K. Winding edektroiagntstov uncoupled w attached to battery K through disconnecting g, acting simultaneously with the counter, and in the common circuit of battery K includes contacts y and z, closing the circuit through the housing of the arm and rocker when lowering the right shoulder on the last one.

If we balance the yoke with the cup, oh without the ball, with the help of the load and with the load with the help of the load and balance the weight put on the weighing pan and corresponding to the minimum weight g of the object, then all other weights can be obtained with the weight of the ball Q, at which the displacement of the latter along the rocker to the right for some length will be equalized by an increase in the load on the cup by the value of one class gap. Selecting further the width of each of the contact plates r equal to this length, having them appropriately relative to the zero position of the ball Q, can be achieved by moving the closure ball of one of the chains a, at the equilibrium moments of the rocker arm and, therefore, turning on the counter corresponding to the defined a class within which the object lies on the cup.

In order to achieve automatic operation of the device through the common conductor 6 of the circuit, the counters are opened immediately after the action of any ps of the latter with the help of an electromagnet w, the winding of which is closed; Kachts on the battery By swinging gami counters.
