Synthesis of Mica
A synthetic fluorophlogopite mica (KMg3A1Si30 IO F 2), in which the (OR) ions that are normally found in normal micas were complet.ely replaced by fluorine, has been syn thesized. This material has essentially the same physical and electrical properties as natural phlogopite mica, except with somewhat lower flexibilit…
Free Radicals by Mass Spectrometry. I. The Measurement of Methyl Radical Concentrations
A method has been developed for measuring the partial pressure of methyl radicals in thermally decomposing gases, using a modified mass spectrometer. The sensitivity of the instrument to methyl radicals has been determined by decomposing known quantities of mercury dimethyl and di-t-butyl peroxide in a stream of carri…

Solubility and fractionation of polyvinylpyrrolidone
Abstract Polyvinylpyrrolidone (PVP) can be conveniently fractionated from water by successive precipitation with acetone, from chloroform with ether, or from ethanol with benzene. The major part (60–70%) of the common PVP has the intrinsic viscosity of 0.12–0.30. The fractions can be liberated from the low molecular c…

Nuevas técnicas para el estudio del fraguado de los aglomerantes hidráulicos
En el presente trabajo se trata de establecer experimentalmente las diferencias entre los comentos aluminosos y los portland en cuanto a su comportamiento frente a una nueva técnica que ya fue descrita (1) (2), para determinar el tiempo de fraguado (principio, fin e intervalo), basada en las variaciones de resistencia…

Theory of Jet Formation by Charges with Lined Conical Cavities
An article by Birkhoff, MacDougall, Pugh, and Taylor (see reference 1) presented hydrodynamic theories of jet formation and target penetration by explosives with lined conical cavities. However, it was unable to explain satisfactorily why the jets produced are several times as long and, therefore, several times as eff…
