Abstract: ABSTRACT    An antigenic protein, termed antigen A, present on the cell walls and in cultures of Streptococcus mutans, especially genetic group I (serotypes c, e and f) is separated from other antigenic proteins, notable those which cross-react with heart tissue, to give an antigenic preparation which may be used as a vaccine or to raise antibodies for use in protecting against dental caries.      Antigen A is one of two major antigenic proteins remaining on cell walls of S. mutans genetic group I after extraction with a boiling 10 litre aqueous solution of sodium dodecyl sulphate for 20 minutes.  It has a molecular weight of about 29,000, an isoelectric point of 4.1 to 4.5.  Its amino-acid analysis is also given.      The antigen also occurs in the culture filtrate and/or cell extract and may be readily purified from these sources by, for example fractional ammonium sulphate precipitation and/or affinity chromatography on immobilised antibody.

Abstract: Perfectionnement aux procédés et dispositifs d'extrusion hydrostatique continue.  En vue de diminuer les fuites de fluide visqueux par les jeux entre rotor et stator nécessaires au fonctionnement de l'appareil, on utilise dans la saignée du rotor, pour faire avancer l'ébauche, un fluide moteur ayant une viscosité supérieure à celle du fluide situé dans la chambre isostatique où règne la pression d'extrusion. La puissance de pompage est, ce de fait, fortement diminuée, et on peut éviter l'emploi de multiplicateurs de pression coûteux et fragiles.  L'invention est applicable à l'extrusion hydrostatique continue de métaux.

Abstract: ABSTRACT OF THE DISCLOSURE      An improvement to the basic concept of storing sludge (i.e., fines) in the interstices between the sand grains of a dike associated with a tailings pond is disclosed.  The sludge is first treated with hydrolyzed starch flocculant to obtain improved permeability and shear strength characteristics. Thereafter, the treated sludge is mixed with sand to obtain the fines-containing dike building material which is stronger than that obtained by mixing untreated sludge with sand and thus permits a higher dike in which to store increased quan-tities of fines.

Abstract: ABSTRACT OF THE DISCLOSURE This  invention describes  a double wall  step-liner construction for a combustion chamber of a combus-tion  turbine.   The  chamber  is  a  series of concentric cylindrical  segments  stacked  in overlapping arrangement such that the leading edge of each outer segment and the terminal edge of each inner segment are in general axial alignment so as to form a continuous double wall through-out  the  axial  length of  the  step-liner configuration. Each cylindrical segment is attached at its inlet end and at its outlet end to the adjacent cylindrical segment by an annular transition member formed of a wire mesh secured to each respective cylindrical segment with high tempera-ture brazing.  The relative thermal expansion between the inner  and outer cylindrical segments  (both axially and radially) is accommodated by deflection and distortion of the wire mesh transition members which also permits cool-ing air to enter between the overlapping segments and to be discharged therefrom into the combustion chamber with minimum interference.

Abstract: Abstract of the Disclosure The invention provides optical measuring apparatus including a laser which is arranged to have an output of electromagnetic radiation including at least two different simultaneously-generated frequencies.  This output is fed to a detector, such as an optical diode, which produces a corresponding electric signal at the difference (beat) frequency.  The beat frequency, any change in the beat frequency, or any rate of change of the beat frequency can now be examined electrically to the degree of accuracy generally available in that art, usually to a much higher degree than is available in the optical or mechanical arts.  The parameter to be examined may be that of an element causing the production of the beat frequency such as a birefringent material, or may be that of an element which changes the frequency in some way, such as an angular orientation of two quarter-wave plates.

Abstract: ABSTRACT             A rotary expansion power unit, such as a steam engine, which has a planetating rotor in a housing having an epitrochoidal cavity.  In known engines, hot expansion fluid is directed through a hollow interior in the rotor and surrounds the rotor journal bearing.  This leads to excessive expansion of the rotor and requires an excessive flow of cooling oil to the bearing.  The invention isolates the expansion fluid from the interior of the rotor by having a valve disc fastened to the rotor crankshaft with a first seal means between the valve disc and housing end wall and a second seal means between the valve disc and rotor.
