The electrical condition of a gold surface during the absorption of gases and their catalytic combustion
Authors: Hartley Harold Brewer
Published: December 2006

In 1905 Bone and Wheeler, in their memoir upon "The Combination of Hydrogen and Oxygen in Contact with Hot Surface," drew attention to the possible connection between the electrical conditions of hot surfaces and their power of rendering "condensed" or "occluded" gases chemically active. Shortly afterwards Bone and Makower, in a series of unpublished experiments, observed that a gold surface becomes negatively electrified during the catalytic combination of hydrogen and oxygen at 300° or there abouts. The recent inventions, by Bone and his co-workers, of processes of "flameless incandescent surface combustion," whereby the constituents of an explosive gaseous mixture, in correct combinig proportions, are caused to combine at a highly accelerated rate, and without development of flame, in contact with (or within the pores or interstices of) an incandescent solid, have again called attention to the important
rôle
played by hot surfaces in accelerating combustion, and to the great economic advantages derivable thereform. The phenomenon is now known to depend upon a peculiar "activation" of the combustible gas, and probably of the oxygen also, by association with the surface. At relatively low temperatures the intensity of such action varies with the chemical characters and physical condition of the surface, but it rapidly increases with the temperature until at bright incandescence there is little to choose between the catalysing power of chemically different surfaces, porosity and refractoriness being now the dominant factors.
Stark effect in iron and the contrast with pole effect
Authors: Panter S. F. , Foster John Stuart
Published: December 2006

In the operating conditions of the iron arc there are a number of influences which may measurably affect the universally accepted standards of wave-lengths. Since this phenomenon appears to have some complexity, it is important to learn what part may be played by pure Stark effect. Already it is known that an increase of pressure within the source causes small shifts in the wave-lengths of most iron lines (pressure shift), which according to Babcock (1928) is always toward the red. This effect appears to be different from the so-called pole effect which consists of a relative change of wave-length at the pole as compared with that at the centre of the arc. For it is found that in the latter effect the shift is toward the red for some lines and toward the violet for others. In recent years the pole effect has been rather generally accepted as a pure Stark effect due to electric fields developed by the relatively large drop of potential near the pole. This view has indeed been taken as a result of earlier examinations of the Stark effect for iron in which the displacements of a few lines were reported to have the same sign as their pole effects.
Metallic reflexion and the surface photoelectric effect
Authors: Mankinson R. E. B.
Published: December 2006

1—The photoelectric effect at metal surfaces is of great importance and many attempts have been made to explain its main features, but an exact theory presents great difficulty. One of the best and most recent is that of Mitchell (1934, 1936), who considered an idealized model in which the potential barrier at the surface was a simple step; the field of the light wave was calculated by the classical optical theory, assuming that the optical constants change abruptly at the surface. The latter approximation is not a good one, even for the simple potential jump, sines the electron density does not tall sharply to zero, but decreases in a distance of about 3 × 10
-8
cm. from a high value inside the metal to a negligible value outside the jump. It is well known that a free electron gives no photoelectric effect, and so the photo-emission from a metal is almost entirely due to the surface-potential gradient; it is in this region that the light wave is least accurately given by the simple optical theory and fluctuates most.
The posterior probability distributions of the ordinary and intraclass correlation coefficients.
Authors: Jeffreys Harold
Published: December 2006

1. The accurate form of the probability distribution of an estimated correlation coefficient in a simple, the true correlation being taken as a datum, has been given by Fisher in two well-known papers (1915, 1921). Pearson and others (1917) have studied the adaptation of the formula, which is rather complicated, for numerical work, but a transformation suggested by Fisher in his earlier paper and applied in his late one offers great advantages. The present paper deals with the inverse problem: given the estimate from a sample, what is the probability distribution of the true value, the latter being supposed initially unknown? Much of the mathematics of correlation depends on the hypothesis of the normal correlation surface. As this is a generalization of the normal law of error for one variable, it is subject to similar criticisms. It can be derived from the hypothesis that the two variables considered are subject to a number of independent component disturbances,
m
of which effect both in the same sense and
n
in opposite senses (Jeffreys 1935, pp. 213-17). If they are all equal in amount, then even if
m
and
n
are fairly small they lead to a good approximation to the normal correlation surface with correlation (
m - n
)/(
m + n
). We could regard
m
/(
m + n
) as a frequency to be estimated from a sample, and such frequencies are taken, in the absence of special knowledge, as having their prior probabilities uniformly distributed. The idea of the normal correlation surface therefore suggests that we should take the prior probability of the correlation coefficient as uniformly distributed between - 1 and + 1.

Last evening (March 7) I succeeded in obtaining a photograph of the spectrum of the great nebula in Orion, extending from a little below F to beyond. M. in the ultra- violet. The same spectroscope and special arrangements, attached to the 18-inch Cassegrain telescope with metallic speculum belonging to the Royal Society, were employed which, have been described in my paper on “The Photographic Spectra of Stars.”
IV. A possible explanation of the two-fold spectra of oxygen and nitrogen
Authors: Baly Edward Charles Cyril , Ramsay William
Published: December 2006

The two spectra of oxygen are shown to be of a different nature. They behave differently, and reasons are given for their being in all probability the spectra of different gases. They may either be two spectra produced by different vibrations of the oxygen molecule, or they may be the spectra of two different modifications of oxygen, or the spectra of two distinct gases resulting from a dissociation of oxygen, a combination of which is called oxygen. It appeared worth while to undertake experiments with a view of testing the last of these.

On the general circulation of the atmosphere in middle and higher latitudes.
Authors: Shaw William Napier
Published: December 2006

In the course of an investigation into the trajectories, or actual paths of air, by means of synoptic charts, which is still in progress,* it became apparent that the paths of air taking part in cyclonic dis­turbances near the British Isles when traced backward did not always originate in anti-cylonic areas, but followed a track skirting the neighbouring high-pressure areas and traversing sometimes a very large part of a belt of the earth in a direction more or less parallel to a line of latitude, and, on the other hand, air moving in the neighbour­hood of a cyclonic depression did not invariably seek the nearest baro­metric minimum, but sometimes passed on, leaving the circulation of the depression on the left hand.

Authors: Caldwell Robert John , Armstrong Henry Edward
Published: December 2006

The study of the action of asymmetric hydrolytic agents on the sugars acquires interest from the fact that enzymes, which exhibit most remarkable activity as hydrolysts, are apparently all asymmetric in structure. The only experiments of the kind made hitherto are those by Emil Fischer, on the action of
d
- and
l
-camphoric acids on cane sugar, described in his memoir on the importance to Physiology of Stereochemistry. No difference was detected; but as the experiments were made at 90° C. in sealed tubes, it was desirable to extend the inquiry and to operate under conditions more nearly comparable with those under which enzymes act.

Authors: Armstrong Edward Frankland , Caldwell Robert John , Armstrong Henry Edward
Published: December 2006

In accordance with the theory put forward in our former paper, it was to be expected that on hydrolysing cane sugar with sufficiently dilute acids the course of the change would not follow the simple logarithmic law but that it would approximate, during the earlier period, to a linear function of the time. This supposition has been confirmed by experiments made very carefully to test this point.

Published: December 2006

In a paper on reaction-velocities in heterogeneous systems, Nernst has recently put forward the view that all chemical reactions taking place on the boundary of two phases proceed to equilibrium practically instantaneously, and that the velocities actually observed are simply those with which diffusion and convection renew the reacting material at the boundary. As a special instance of heterogeneous reactions, he mentions catalytic decompositions due to finely divided particles, such as colloidal metals, and he believes it probable that the kinetics of these reactions can be deduced from the assumption that chemical equilibrium remains permanently established on the surface of the particles.

The theory of symmetrical optical objectives.—Part II.
Authors: Chalmers S. D. , Larmor Joseph
Published: December 2006

As regards the defects which depend only on those terms in the characteristic function T, that were examined in Part I, the results of that paper would justify the practice of correcting a single component—the back one—for astigmatism and spherical aberration, provided due attention be paid to the securing, at least approximately, of the condition for no distortion. But for the values of aperture-ratio and angular field, that obtain in practical systems, the terms of higher orders in T introduce important aberrations, and it is interesting to examine how far the conclusions stated in Part I are justified in the case of practical systems.
On the modulus of torsional rigidity of quartz fibres and its temperature coefficient.
Authors: Horton Frank , Thomson Joseph John
Published: December 2006

The author recently had the honour of reading to the Society the (results of some experiments in which a new method of timing by means of “coincidences"—a method devised by Professor Poynting—was applied to an investigation of the effects of changes of temperature on the modulus of torsional rigidity of metal wires. It seemed desirable to repeat similar experiments with quartz fibres, seeing that now they are almost universally employed as suspensions in torsion instruments where accuracy is required. The fibres experimented on were prepared from different crystals of quartz, and care was taken in their manufacture so as as to obtain them free from air bubbles and of circular cross-section.
On the colouration of glass by natural solar and other radiations.
Authors: Crookes William
Published: December 2006

It is well known that many samples of colourless glass containing manganese slowly assume a violet tint when exposed to sunlight. This effect is frequently seen in plate-glass windows having a southern aspect; watched from year to year they assume a more and more pronounced amethystine hue. The introduction of manganese into glass is to neutralise the colour caused by the presence of iron. Iron gives the glass a greenish tint, and the addition of manganese binoxide performs the double object of oxidising the green proto-salt of iron to the per-salt, and also of imparting a purple shade which neutralises the green-yellow tint of the silicate of peroxide of iron.
The origin and growth of ripple-mark.
Authors: Ayrton Hertha , Ayrton William Edward
Published: December 2006

The object of the investigation was to determine how ripple-mark started in perfectly smooth sand, apart from accidental variations of surface friction; how the ripples grew; how the amplitude and depth of the water affected them; and whether there was any connection between ripple-mark and kindred phenomena, such as the dust figures in a Kundt’s tube. In the course of the investigation the causes, form, and mode of action of “ripple vortices” in the water were determined, and the fact that no vortices of this kind can form in a current flowing steadily in one direction
over
an obstacle was demonstrated, both theoretically and practically. Also many minor details came to light, such as the fact that each ripple is continually travelling, as a whole, and why it does so.

Symmetry concepts for the geometric analysis of mixing flows
Authors: Franjione J. G. , Ottino J. M. , Smith F. T.
Published: December 2006

Much of the recent analysis of chaotic mixing has focused on utilizing tools and techniques imported from dynamical systems theory. However, most techniques require detailed information about the velocity field or fluid motion and are restricted to conditions where the ‘degree of chaos’ is small. Symmetries provide a method of analysis without specific reference to exact mathematical expressions. Symmetry concepts are illustrated in terms of a prototypical system called the eggbeater flow. Although a family of 32 different eggbeater flows can be constructed, symmetry arguments reveal that only four of these are independent. These flows serve to illustrate the role of islands in mixing. If a flow possesses symmetry, islands are found in symmetric arrangements, the simplest cases being reflections and rotational symmetries. A knowledge of symmetries provides the basis for systematic methods for destroying islands. These ideas are developed in terms of the eggbeater flows, and are subsequently extended to a class of three-dimensional continuous throughput flows - duct flows - which are of a more practical interest from an engineering viewpoint. Three such duct flows are studied. Using symmetries, we show that these flows are topologically identical to the eggbeater flows, even though their geometries and flow mechanisms are quite different from the eggbeater flows. Lastly, we demonstrate how the same methodology for destroying islands and enhancing mixing in the eggbeater flows can be applied to duct flows.
Flame stretch rate as a determinant of turbulent burning velocity
Authors: Bradley D. , Lau A. K. C. , Lawes M. , Smith F. T.
Published: December 2006

A rational basis for correlating turbulent burning velocities is shown to involve the product of the Karlovitz stretch factor and the Lewis number. A generalized expression is derived to show how flame stretch is related to the velocity field. A new dimensionless correlation of experimental values of turbulent burning velocities is presented. Dimensionless groups also are used in correlations of laminar and turbulent flame extinction stretch rates. A distribution function of stretch rates in turbulent flames, based on an earlier one of Yeung
et al
., is proposed and the experimental data are well predicted by a theory based on flamelet extinction by flame stretch with this distribution. Uncertainties arise concerning the role of negative stretch rate. Laminar flamelet modelling of complex combustion appears to have a broader validity than might be expected and some explanation for this is offered.
Proposed experimental tests of a theory of fine microstructure and the two-well problem
Authors: Ball J. M. , James R. D.
Published: December 2006

Predictions are made based on an analysis of a new nonlinear theory of martensitic transformations introduced by the authors. The crystal is modelled as a nonlinear elastic material, with a free-energy function that is invariant with respect to both rigid-body rotations and the appropriate crystallographic symmetries. The predictions concern primarily thetwo-well problem, that of determining all possible energy-minimizing deformations that can be obtained with two coherent and macroscopically unstressed variants of martensite. The set of possible macroscopic deformations obtained is completely determined by the lattice parameters of the material. For certain boundary conditions the total free energy does not attain a minimum , and the finer and finer oscillations of minimizing sequences are interpreted as corresponding to microstructure. The predictions are am enable to experimental tests. The proposed tests involve the comparison of the theoretical predictions with the mechanical response of properly oriented plates subject to simple shear.
