Abstract: A method for measuring particle size distributions of bulk materials such as cereals, cereal milling products, cereal products and the like, which is intended to enable the measurement of particle size distributions which vary by orders of magnitude. A sample of isolated particles is optically detected in an arrangement by at least two measurement methods. Preferably, detection of the contours of the particles and laser diffraction take place at the same time.

Abstract: Method for measuring particle size distributions, in particular for the optical measurement of wide particle size distributions of bulk materials such as cereals, cereal milling products, cereal products and the like, which is intended to enable the measurement of particle size distributions which vary by orders of magnitude. To address this problem, a sample of isolated particles is optically detected in an arrangement by means of at least two measurement methods, wherein preferably detection of the contours of the particles and laser diffraction take place at the same time.

Abstract: An apparatus and method for inserting a stopper into a medical syringe minimizing the amount of entrapped air between the stopper and the contained liquid. The apparatus in a first embodiment utilizes a vacuum to assist inserting the stopper within the syringe. In a second embodiment a vacuum is used to transport the stopper and cause the insertion into the syringe. This method eliminates a mechanical device that transports the stopper to the syringe.
