Abstract: A synchrocrusher for making a material collide in which the rotor is designed with a symmetric configuration; that is, the rotor contains equal numbers of respectively forward and backward directed guide members and co-rotating impact members which are arrranged, as associated (synchronized) pairs, in each direction of rotation; which pairs are circumferentially disposed uniformly at equal angular distances around the axis of rotation with the forward and backward directed configurations mirror imaged (symmetrically) to each other. By combining or joining together pairs of respective forward and backward directed guide and co-rotating impact members, in respective guide and impact combinations and guide and impacts units, a supersymmetry configuration is achieved, which is very effective and allows for many interesting synchrorotor configurations.

IPC: G01N33/34
Filed: 2000-12-20
Abstract: A rapid method is provided for the on-line spectroscopic determination of lignin content and/or kappa number in wood pulps. Unlike currently available commercial instrumentation, the method enables one to measure lignin content independently of species variations and pulp consistency.      The method includes the steps of: (1) withdrawing high-consistency samples of wood pulp from a chemical pulp manufacturing process; (2) subjecting these samples to a monochromatic visible-light source; (3) recording the resulting scattered light and its Raman spectrum over a predetermined range of wave numbers so as to produce Raman-scattered light intensity measurements; (4) determining either the uncorrected, baseline-corrected and/or integrated Raman-scattered light intensity of the samples over a predetermined range of wavenumbers shown by different combinations of lignin content, cellulose content, and consistency; (5) correlating by either univariate or multivariate calibration the relationships between the Raman-scattered light intensity measurements of unknown samples and the Raman-scattered light intensity shown by known combinations of lignin content, cellulose content, and consistency so that the lignin content and/or kappa number in wood pulps can be accurately determined over a Kappa range of 5 to 110 and preferably 5 to 20, for any levels of sample cellulose content or pulp consistency.

IPC: B01F29/62
Filed: 2001-02-12
Abstract: Mixing of components, e.g. pharmaceutical actives and excipients, is carried out while monitoring the spectroscopic profile of the mixture during the mixing process so that the spectroscopic profile may be used to determine the point at which mixing is terminated. In one embodiment of the invention, the spectroscopic data is collected by means of a monitoring unit mounted on the mixing vessel. the mixing vessel being mounted and driven so as to rotate or oscillate mounted and thereby effect mixing of its contents and the monitoring unit being mounted for rotation or oscillation with the vessel. When the spectroscopic data indicates that mixing has progressed to a desired state, e.g. the production of a homogeneous blend, the monitoring unit transmits a signal to the drive source to terminate rotation or oscillation of the vessel.

Title: Segmented rolled food item
Inventor: DRUMMOND WILLIAM R
IPC: B65D75/58
Filed: 2002-10-07
Abstract: A segmented rolled food item is continuously produced using a rotating segmenting roller having a plurality of parallel circumferential lanes each of which contains a series of circumferentially spaced knife edges that are disposed at least substantially parallel to the axis of rotation of the roller and that project radially outward from the surface of the roller. The surface of the roller may also include a plurality of embossing cups or imprinting cups having a knife edge that protrudes radially outward from the surface to form at least one definite shape in each of the multiple strips of food. The segmented rolled food item is produced by feeding multiple continuous at least substantially parallel strips of a flowable food product, each of which are deposited on pre-slit parallel strips of support material, between the nip of an upper anvil surface and the lower surface of the rotating segmenting roller to segment the food. The segmentation may be by a complete, straight cut or by a perforated cut at least substantially or completely across the width of the food strip. The segmentation and embossing of the food strip occurs without segmentation or embossing of the support strip. After segmenting the food, both the strip of food and the support material are cut into lengths to form leading and trailing ends. Then each strip of food is rolled around a leading end of the support material to obtain a segmented, rolled food item.
