Fig. 15 Effect of single-shot-grade ethylene/vinylacetate (EVA-ss) on the yield stress of 4 wt % paraffin wax gels in decane at 0 as a function of wax modifier concentration the relative yield stress and symbols are as defined in the caption for Fig. 14...

Shot blasting room A ventilated room devoted to the cleaning of castings by the use of various grades of shot. 

A motorist fills his tank at a Union 76 service station where two out of three grades of gasoline cost more than 2 per gallon (March 7, 2000). West Coast fuel prices on the spot market shot up in reaction to the highest oil prices in nearly a decade. (Corbis-Bettmann)... 

Test samples have been prepared from a 3 mm hot-rolled steel sheet which showed an intact mill scale (Degree A of Swedish Standards, SIS-055900), Thereafter they were shot blasted with S-280 to reach the ASa3 standard, prior to the application of the paint coating. Surface preparation B St 2 was obtained by wire brushing a steel sheet of Grade B obtained in turn by oxidation of Grade A sheet in a contaminant free atmosphere. In "Table I.", the characteristics of the paints used in this study are shown. 

This paper takes the form of overhead slides which discuss the foaming of polyethylene in rotational moulding. Discussed are the characteristics of PE foam, its applications and processing, physical properties, one-shot foam, and a third generation rotational moulding grades with improved flow properties. 

Arsenic. As, at wt 74.91 exists in three modifications all corresponding to the formula As4i mw 299.64. The most common form is the crystalline or a-form, known also as metallic arsenic. Its mp is 814° at 36 atm press, sublimation point 615, d 5 = 72 at RT (5.6-5.9 for commercial grade) and hardness 3.5 Mohs. Prepn props are given in Refs 1-6 toxicity, fire expln hazards of As dust are discussed in Ref 7. Arsenic is used in some alloys and for hardening lead shot... 

The three main types of coke that are produced in a delayed coker are typically categorized as needle coke, sponge coke and shot coke. Needle coke is a premium grade coke, which is considered a specialty coke and is produced from specific aromatic feedstocks. 

The regular grades of coke are sponge coke and shot coke. A short description of each type of coke follows. 

Grade Electrolytic, ingot, pellets, shot, sponge, powder, high-purity strip, single crystals.
