The Heat Sensitivity of Hevea Latex. I. The Action of Zinc-Ammonium Complexes

Paul Cassagne1952-06-01Rubber Chemistry and Technology

Abstract Among the different processes for heat-sensitizing latex by the more or less direct action of zinc-ammonium complexes, one has the choice of inorganic and organic complexes. Among the inorganic complexes, zinc-ammonium nitrate seems to be the most effective. Prepared from a 5 N solution of zinc nitrate and 5…

On the thermal decomposition of dolomite. IV.thermogravimetric investigation of the dolomite decomposition

R. Haul、Josua Markus1952-06-01Journal of Applied Chemistry

Abstract The thermal decomposition of dolomite at various constant temperatures and carbon dioxide pressures has been investigated by the ‘loss‐of‐weight method.’ Depending on these conditions, dolomite can be decomposed either stepwise to magnesium oxide and calcium carbonate (‘half‐burnt dolomite’) with subsequent d…

On the use of antibiotics for isolating bacteria-free cultures of marine phytoplankton organisms

C. P. Spencer1952-06-01Journal of the Marine Biological Association of the United Kingdom

In the course of some studies on the kinetics of growth and the biochemical activities of a marine diatom it became desirable to obtain bacteria-free cultures. The classical method of obtaining such pure algal cultures involves either repeatedly washing single cells in sterile medium or obtaining discrete bacteria-fre…

Radiation effects in solids

Frederick Seitz1952-06-01Physics Today

As far as I am aware, this is the first invited session of the American Physical Society devoted to the topic of radiation effects in solids—a field that has been an active one for nearly a decade. I believe it is safe to say that it will not be the last such session. The long delay in this event arises, of course, fr…

Neutron Diffraction Study of the Crystal Structure of Ammonium Chloride

Henri A. Lévy、S. W. Peterson1952-06-01Physical Review

The crystal structure of the room-temperature phase of ammonium chloride has been determined by powder and single crystal neutron diffraction methods. The N---H links are directed essentially toward four of the eight surrounding chloride ions, and, contrary to a recent report, the two orientations fulfilling this cond…

The System Alumina‐Gallia‐Water

V. G. Hill、Rustum Roy、E. F. Osborn1952-06-01Journal of the American Ceramic Society

A study of the system Al 2 O 3 –Ga 2 O 3 –H 2 O has resulted in the determination of equilibrium diagrams for the systems Al 2 O 3 –Ga 2 O 3 and Al 2 O 3 .‐H 2 O–Ga 2 O 3 .H 2 O. Extensive solid solution characterizes the α ‐Al 2 O 3 and β ‐Ga 2 O 3 structures at high temperatures, but it is shown that below 810°C. a…

Density, Expansivity, and Viscosity of Molten Alkali Silicates

L. Shartsis、S. Spinner、W. Capps1952-06-01Journal of the American Ceramic Society

The densities nd vi cositie of melts in the systems Li 2 O–SiO 2 , Na 2 O–SiO 2 , and K 2 O–SiO 2 were measured with a restrained sphere apparatus over the temperature range 1000° to 1400°C. At the higher temperatures in this range the density in each system decreased with increasing alkali content. On a mole basis th…

LX. The formation of immobile dislocations during slip

Alan Cottrell1952-06-01The London Edinburgh and Dublin Philosophical Magazine and Journal of Science

Summary Lomer has pointed out that certain dislocations on intersecting slip planes in the face centred cubic lattice can join to form new dislocations. It is now proposed that these new dislocations dissociate into groups of imperfect dislocations which cannot move because of the arrangement of their associated stack…

Friction between single fibres

Nils Gralén1952-05-22Proceedings of the Royal Society of London A Mathematical and Physical Sciences

Abstract Single textile fibres are of the order of magnitude of 10 to 50μ in thickness. The measurement of friction between them in a longitudinal direction therefore offers some experimental difficulties. Two forms of apparatus have been designed. One measures the friction between two fibres crossed at a small angle.…

The crystal structure of β dicalcium silicate

C. M. Midgley1952-05-02Acta Crystallographica

The crystal structure of fl dicaleium silicate (Cap SiO4) has been determined from X-ray oscillation, rotation and Weissenberg photographs. The mineral is monoclinic, space group P21/n, with cell dimensions a = 5-480.02, b ----6.76-b0.02, c ----9"28-}-0-02 A; fl --94 33'. There are four molecules in the unit cell. The…

Aeration and Foaming in Lubricating Oil Systems

R. Tourret、Norman A. White1952-05-01Aircraft Engineering and Aerospace Technology

DESPITE the quite extensive literature on foam, the mechanism of its formation and decay does not appear to be widely appreciated. Most fundamental research has been orientated towards maximum foam in aqueous solutions, whereas the desire in aircraft engines is for minimum foam in oil ‘solutions’. Further, the numeric…

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…
