Abstract: The invention relates to a process and device for detecting foreign bodies in a liquid, wherein the image of the apparent surface of the liquid in rotation in the immobilized recipients is formed, by reflection, diffraction, refraction or attenuation of the light coming from a source, on a matrix of reception and read cells. In the matrix each cell is perfectly delimited and its position is identified by numerization. A series of images is produced, of which a certain number are taken as reference and memorized. Each image is digitized and those images following the last memorized image is compared therewith cell by cell by a subtractor. The results of such a subtraction are compared with a threshold and results overstepping the threshold involve delivering a signal to a processor which controls a sort device arranged to eliminate undesirable units.

Title: Method for the monitoring and control of microbial populations
Inventor: BLACKBURN JAMES W
IPC: C12Q1/68
Filed: 1986-03-04
Granted: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE         A method is disclosed for the monitoring and control of a microbial population in a biotechnological  system.   The method involves the  identification of at least one critical subpopulation  and  determining  the  optimal  level  for  said subpopulation.   A controlled variable is determined which can be  adjusted  to  alter  the  level  of the subpopulation.   The method employs nucleic acid hybridization with a labelled probe to determine the level of the subpopulation in the microbial population.   This involves the preparation of a labelled probe from nucleic acid having a nucleotide sequence substantially complementary to a nucleotide sequence in the nucleic acid in the  subpopulation.   A representative sample of the microbial population is obtained and treated to free nucleic acids and to denature double-stranded nucleic acids.   The resulting sample nucleic  acids  are  contacted  with  the  labelled probe under appropriate conditions to form duplexes.  The labelled probe in the duplexes is monitored to determine the amount of duplexes and  the  level  of  the  subpopulation  is  calculated  from the determined duplexes.  The controlled variable is adjusted based on the calculated level of the subpopulation to bring the level toward the optimal level.   The method is used to monitor and control  the  microbial  population without  reliance  upon  the phenotypical  expression  of  the  genetic  information  of  the organisms.

Title: Bitumen - polyolefin compositions
Inventor: WOODHAMS RAYMOND T
IPC: C08L95/00
Filed: 1986-03-04
Granted: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE          Bitumen - polyolefin compositions, e.g. for use as binders in paving compositions, are stabilized by an emulsifier system comprising a polyolefin wax with terminal functional groups and a polymeric main chain structure which is compatible with the polyolefin of the dispersed phase of the binder.  In a preferred embodiment, the emmulsifier system also includes a metal oxide compound which will chemically react with the terminal functional groups.  Especially preferred is maleated polyethylene wax and ferric oxide.  The emulsifier system forms a sheath of inorganic material around the dispersed polyolefin droplets, to stabilize them and to hinder their floatation to the surface of the binder composition.

Abstract: ABSTRACT OF THE DISCLOSURE         The conventional earpiece for a telephone handset includes a raised outer periphery surrounding a depression, the bottom of which is perforated for facilitating the transmission of sound from a receiver to the ear of the user.  During normal usage, the raised periphery of the earpiece presses against the earlobe of a user.  If the user is wearing an earring, use of the handset even for a short period of time can be uncomfortable.  Often the user removes the earring prior to placing the handset against the ear.  A simple solution to this problem is to provide a radially extending notch in the raised periphery of the earpiece for accommodating the earlobe and the earring of the user.  Pre-ferably the position of the notch can be changed to suit the particular user.
