Abstract A rapid method for the separation of light filth from a variety of high bran flours consists of a defatting procedure in a Soxhlet extractor, followed by separation of the filth elements with mineral oil in a HCl-ethyl alcohol medium. The proposed method gives clean papers and good recoveries and has no critically timed steps.

Abstract A rapid method based on product defatting in a Soxhlet extractor, hydrolysis in acid-alcohol, water washing, and, finally, separation of light filth in mineral oil has been developed for the separation of light filth from white and yellow corn meal, cracked wheat, rye, pumpernickel, and buckwheat flour. Collaborative results are satisfactory for all products tested; the method has been adopted as official first action.

Abstract A rapid method, based on acid hydrolysis in the presence of mineral oil, has been developed to separate extraneous materials from whole and degerminated corn meal, prepared mustard, and soy flour. Corn meal may be first examined for rodent excreta by method 36.032 and then examined for light filth, or it may be analyzed directly for light filth by the acid hydrolysis method. Soy flour is prepared for analysis by solubilizing the protein in dilute sodium chloride solution in the presence of mineral oil. The Kilborn separatory funnel is used with all 3 products. The proposed method improves recoveries of insect fragments by 13—34% and rodent hair recoveries hy 25—54%. Analyst time required for actual assay is reduced by at least onethird. The method will be subjected to collaborative study

The first appearance of tungsten-free hard alloys (TFHA) was noted in the early 30s of the last century, but they did not receive due attention and, accordingly, spread due to insufficient strength and were replaced by tungsten-containing alloys of such groups as VK, TC and TTK. However, the rapidly developing shortage of expensive tungsten pushed in the late 50s to return to the search for hard alloys, the composition of which does not include tungsten. Due to the growing demand for tungsten-free hard alloys, the problem of recycling their waste with the possibility of reuse is acute in the industry. The purpose of this work was to conduct x-ray spectral microanalysis (RSMA) of powder material (PM) obtained by electroerosive dispersion (EED) in ethyl alcohol from waste of a non-tungsten hard alloy of the KNT16 brand. The resulting powder material was examined using an energy-dispersion x-ray analyzer from EDAX, built into a scanning electron microscope "QUANTA 600 FEG". In the course of scientific research, the spectra of characteristic x-ray radiation on the surface of the experimentally obtained sample were obtained. The results obtained in the course of scientific research can be used to create environmentally friendly resource-saving processes for processing waste of tungsten-free hard alloys into powder materials.

A study was undertaken to determine if the time elapsed, i.e., settling time, after homogenizing grain flours and meals in a primary diluent and withdrawing samples for serially diluting and plating has an effect on populations of yeasts and molds detected. Sixty samples of flour and meal were analyzed. Samples were withdrawn from the top, middle, and bottom areas of graduated cylinders containing homogenates after settling times of 0, 2, 6, and 10 min and plated on dichloran 18% glycerol agar and dichloran rose bengal chloramphenicol agar. As the settling time between homogenizing plain and self-rising wheat flours and rye flour increased, the population of fungi detected in the top area of primary homogenates decreased significantly (P ≤ 0.05), whereas the population detected in the bottom area increased significantly. Dichloran 18% glycerol agar was clearly superior to dichloran rose bengal chloramphenicol agar for recovering fungi from wheat and rye flours, regardless of settling time. Populations detected in buckwheat flour and in plain and self-rising corn meal were largely unaffected by settling time, sampling location, and recovery medium.

Although detection thresholds for odors are commonly measured in academic and medical settings, the influences of procedural factors on threshold values are poorly understood. The present study evaluated the influences of (i) trial sequence position and (ii) diluent type on the threshold value for the rose-like odorant phenyl ethyl alcohol. In Exp. 1, detection thresholds were measured in 24 subjects on two occasions in which different diluents were used in the concentration series, propylene glycol and light mineral oil. The thresholds were estimated using a 7-reversal initially ascending single-staircase procedure. Threshold values were significantly influenced by the type of diluent (lower for mineral oil) and trial sequence (lower for later threshold reversals). In Exp. 2, 24 subjects were administered a staircase threshold test which continued through 15 staircase reversals. Continued testing resulted in a significant lowering of the threshold measure. These findings demonstrate the importance of both diluent and test length on detection threshold values measured by a single staircase procedure and emphasize the need for standardization of procedures for threshold testing.

Backscattered Electron

The study of preferred crystallographic orientation (texture) in ceramics is assuming greater importance as their anisotropic crystal properties are being used to advantage in an increasing number of applications. The quantification of texture by a reliable and rapid method is required. Analysis of backscattered electron Kikuchi patterns (BEKPs) can be used to provide the crystallographic orientation of as many grains as time and resources allow. The technique is relatively slow, particularly for noncubic materials, but the data are more accurate than any comparable technique when a sufficient number of grains are analyzed. Thus, BEKP is well-suited as a verification method for data obtained in faster ways, such as x-ray or neutron diffraction. We have compared texture data obtained using BEKP, x-ray diffraction and neutron diffraction. Alumina specimens displaying differing levels of axisymmetric (0001) texture normal to the specimen surface were investigated.BEKP patterns were obtained from about a hundred grains selected at random in each specimen.

The Matrix

Some butterfly martensite nuclei were observed in an Fe-27.6Ni-0.89V-0.05C alloy. The alloy was austenitized at 1200°C for 1 hour. Some samples were aged at 850° C for 40 minutes and quenched in 10% brine at room temperature. All the samples were cooled in ethyl alcohol for martensite transformation.A nucleus in an unaged specimen is shown in Fig.1. The nucleus has certain contrast different from the matrix and is shaped like one wing of a butter fly martensite. The SADP of the circled region is measured to be: da=dh, and approximate to dγ(111) and dm(110) with ∠AOB = 55° . It is similar to [011]f.c.c and b patterns in the anglez ∠AOB and the ratio ra/rb, respectively. The SADP shows that the structure of the nucleus is between f.c.c and b.c.c. The dislocation structure within the nucleus is shown in Fig.2. Their Burgers vectors and line directions are also given in it. There are many long dislocations near it without dislocations piled up as shown in Fig.3.Long dislocations are closed at one end as an envelope.
