CS202121B1 - Magnetic field intensity sensor - Google Patents

Abstract

The transducer is intended for measuring the intensity of stationary and quasi-stationary magnetic fields, where it works as a converter of intensity to a time interval - a period and a change in the ratio of half-periods of rectangular oscillations of the napatium at the output terminals of the sensor. The sensor consists of a bridge, in the measuring branch of which the sensing winding of the ferroinduction probe is connected, and a comparator connected to the diagonal of this bridge. The sensor can be used in aviation, geological survey, mine surveying, high-current electrical engineering and when measuring non-electrical quantities — taking position and angle by rotation.

Description

It is an object of the invention to provide a process for the production of formed protein concentrates of the porous structure.

In the prior art production of molded protein concentrates of the porous structure, a thermoplastic extrusion is used in which, by the action of heat and pressure, the proteins are plasticized and, after extrusion under reduced pressure, a porous structure is obtained. This method of production is demanding on technological equipment, requiring the use of high temperatures and pressures. As a rule, extruded proteins are not formed into fibers.

These disadvantages are overcome by the process according to the invention, which consists in dissolving the proteins in an aqueous solution of sodium or potassium carbonate, respectively. of sodium carbonate and potassium carbonate and the solution is injected into water acidified with hydrochloric acid or other acids.

An advantage of the production method according to the invention is that it does not require the use of high temperatures and pressures and the production method allows the formation of protein fibers of different depths and porous structure.

Example 1

12.5 kg of sodium carbonate with water are added to a 1000 kg casein of 50% dry matter

202 121

202 121 so that the resulting dry weight of the mixture was 20%. After dissolution of the casein, the solution is injected into water acidified with hydrochloric acid to a pH of 4.6.

Example 2

The 40% dry milk protein mixture is dissolved by the addition of an aqueous potassium carbonate solution so that the dry matter solution is 23% and the active acidity p _H 7.0.

Example 3

Soy proteins, previously dissolved in an aqueous solution of sodium carbonate op _H 6.5 and 26% dry solution, are injected into water acidified with hydrochloric acid of active acidity close to the isoelectric point of soy protein.

Example 4

The milk protein mixture of 40% dry matter is dissolved by adding a solution of sodium carbonate and potassium so that the dry matter of the solution is active at 23% and active acidity P ij 7.0. The mixture of proteins was injected into water, made acidic with hydrochloric acid to L _H, 4.8.
