It was previously thought that brewers' yeast, Saccharomyces cerevisiae, was incapable of employing mannitol or sorbitol as a source of carbon during propagation in a catabolite derepressive mode. However many strains of S. cerevisiae can in fact employ mannitol and/or sorbitol in this way. Simple tests reveal those strains that are suitable. Positive action is preferably taken to introduce oxygen...

A method of detecting flaws in the neck finish 1 of a glass container 2, especially "line overfinishes", comprises illuminating the neck finish 1 by means of a light source 3, via a half-silvered mirror 4 mounted at an angle to the axis of the container, and reflecting the image of the neck finish via a rotating dove prism 7 to an image detector 10. The detector 10 may comprise two detector cells ...

A visual display panel suitable for use at high altitude comprises two confronting glass plates 1, 2 sealed at their periphery, the plates carrying electrically conductive tracks such that a luminous electric discharge can be formed between said plates, the discharge taking place through a low pressure gaseous atmosphere confined therebetween, in which the panel is supported in a sealed enclosure ...

A process is provided for manufacturing a composite of a sheet of expanded, porous polytetrafluoroethylene (PTFE) impregnated with another resin, the other resin being impregnated within the pores of the expanded PTFE. The other resin imparts desired characteristics to the composite such as high thermal resistance and low dielectric constant which make it useful as substrates for printed circuit b...
