A survey of the literature and the practice of detergency as applied to textiles has indicated that the manufacture of successful detergents has progressed further than has the fundamental science of detergency. Many of the basic factors in soiling of textile fibers and fabrics, and in cleaning of the soiled materials…
Abstract 1. Es werden die Zustandsdiagramme der Systeme Magnesium‐Calcium, Magnesium‐Strontium und Magnesium‐Barium aufgenommen. 2. Während Magnesium mit Calcium nur eine Verbindung Mg 2 Ca bildet, gibt es in den beiden anderen Systemen je zwei kongruent schmelzende Phasen: Mg 9 X und Mg 2 X sowie eine inkongruent sch…
A bstract Since glasses, which are high in silica or boric oxide content, have high absorption in the region of 2.7 to 3.0 microns, a study of the transmission characteristics of several simple glasses has been made. Measurements of a variety of commercially available samples (5 mm. thick) of fused silica showed absor…

The generation of electrical energy from thermal energy by thermoelectric means cannot be accomplished with thermocouples made of the available alloys generally used for temperature measurements, their efficiency being less than one percent. A review of the theoretical efficiency calculations shows that higher efficie…
This Subcommittee was organized in November 1941. It first selected the areas in which the terminology of sediments was confused and needed clarification, and drew up preliminary definitions to serve as a basis of discussion. These definitions were then distributed as widely as possible among the persons in this count…

The effective permittivity of samples of barium titanate with porosities up to 40% v/v. has been determined, and an explanation given in terms of Wiener's mixture law. It is shown that the values of the form factor in this law can only be predicted with certainty over the ranges 0-30% and 70-100% porosity, and takes u…
A study of the kinetics of the heterogeneous hydrolysis of cellulose indicates that there are two distinct rates which have been attributed to the rapid hydrolysis of the loose amorphous regions and to the slow hydrolysis of the dense crystalline portions of the fiber. Based on this interpretation, a simple method for…
Using the crystal structure determination of rochelle salt made by Beevers and Hughes, a theory of the ferro-electric effect and clamped dielectric constant has been worked out using the displacement of the hydrogen nucleus in the 1-10 hydrogen bond as the ferroelectric dipole. This theory has only one disposable cons…

Abstract : Firings of caliber .50, 20mm, and 37mm A.P. projectiles were made on 4' x 4' x 3' blocks of granite, diabase, quartzite, oolitic limestone, and sandstone. The results of firing major caliber projectiles on limestone at Fort Knox, Kentucky, were obtained from the Armored Board. From the results of the firing…

Abstract The chemical reactivity of vinyl and diene polymers manifested during aging and degradation is similar to the reactivity manifested during polymerization; namely, the activated intermediates are radicals and the reaction proceeds by a chain mechanism. A discussion of the possible types of aggregative and disa…
