Granted: 1990-07-10
Abstract: CYCLONIC SEPARATOR WITH SCREEN AND BALL CHECK ABSTRACT A cyclonic device for separating entrained mat-ter from a fluid stream under pressure includes a vortex chamber having a longitudinally upright cylindrical part and a subjacent frusto-conical part. Inlet and outlet means are provided for causing the fluid stream to flow first in a downward spiral and then along an ascending vortex. The entrained matter is separated from the fluid stream by centrifugal and inertial forces acting thereon from the swirling fluid flow. A cylindrical filter screen is provided concentrically disposed within the chamber and defines an area through which the ascending vortex flows. The filter screen further separates rela-tively less dense matter from the fluid stream prior to the fluid flowing along the ascending vortex. A freely buoyant spherical ball is provided which acts as a check valve to close the chamber outlet means when a predeter-mined level of separated matter accumulates in the cham-ber. The filter screen encloses the ball and loosely constrains the ball to a direction of movement towards the chamber outlet.

Inventor: DUBBELDAM GERRIT C

Granted: 1992-03-10
Abstract: Abstract A process for determining the thickness and/or change in thickness of a thin layer applied to a carrier, with the carrier coated with the thin layer being radiated with a plane polarized light beam and the reflectance on carrier and layer being detected. The light reflected by the carrier and the thin layer is split into a p-polarized part and an s-polarized part, after which the respective reflection values Rp and Rs are measured simultane-ously for the two parts, and the quantity M =    is determined, in which formula m is a variable parameter and the quantity M is a function of the thickness of the thin layer. By measuring both the reflection of p-polarized radiation and that of s-polarized radiation,  and by adroitly combining the measuring data obtained, the resulting signal will be insensitive to the intensity of the radiation source. An additional advantage is that the process has a greater sensitivity to variations in layer thickness, and that it is possible for the process to be carried out within a wide linear measuring range. In determining the growth of a protein layer the measuring result is indepen-dent -within wide limits- of the thickness and the index of refraction of a layer previously applied to the carrier.

Abstract: Abstract A segment (hft) of bacteriophage FP43 DNA cloned into plasmids pIJ702 or pMT660 mediates high frequency transduction of these plasmids by FP43 in Streptomyces griseofuscus.  Lysates of FP43 prepared on S. griseofuscus containing the plasmids with the hft segment also transduce many other streptomyces species, including several species that restrict plaque-formation by FP43 and at least two species that produce restric-tion endonucleases that cut the plasmid DNA.  Trans-duction efficiencies in different species are influenced by the addition of anti-FP43 antiserum to the trans-duction plates, the temperature for cell growth before transduction, the multiplicity of infection, and the host on which the transducing lysate is prepared. Transducing lysates prepared on S. griseofuscus are also able to mediate plasmid transfer to species of Streptoverticillium, Chainia, and Saccharopolyspora.
