Patent number: 8425657Abstract: A method, and an apparatus to reduce and remove liquid droplets in air, such as fog, mist, haze, spray or steam. The mist and/or air borne water or other liquid droplets catching and collection apparatus creates an “electric wind”, especially enforced by charged needle points or line arranged constructions and/or wires of the first electrode and an electric charging of mist and/or air borne water or other liquid droplets, which will be directed by the “electric wind” and the electric field between the electric source and the opposite grounded or opposite charged counter electrode (second electrode) of fine gauze or something comparable.Type: GrantFiled: December 17, 2008Date of Patent: April 23, 2013Assignee: Technische Universiteit DelftInventors: Willibrordus Nicolaas Johannes Ursem, Johannes Cornelis Maria Marijnissen, Rein André Roos

Patent number: 6011621Abstract: Described is an improved method for measuring the particle size of ultrasmall particles (111) which are suspended in a fluid. Laser light (121) is scattered by the particles, and the scattered light (122) is received by a light detector (131) which provides an electrical measuring signal (S.sub.m) which is representative of the intensity of the scattered light (122). According to the present invention, signal components with a relatively low characteristic frequency are removed from the electrical measuring signal (S.sub.m), and the particle size is calculated on the basis of the thus corrected measuring signal (S.sub.c), so that also at a very low concentration of the particles (111) reliable results are achieved.Type: GrantFiled: September 14, 1998Date of Patent: January 4, 2000Assignee: Technische Universiteit DelftInventors: Johannes Cornelis Maria Marijnissen, Alexander Willem Willemse, Rein Andre Roos
