Patent CA-2215754-C (CA)
Inventor: KOELMAN JOHANNES MARIA VIANNEY
IPC: G01N33/24

Granted: 2006-08-22
Abstract: A method of determining a parameter of a physical model representing the electrical behaviour of a composition is provided. The method comprises defining said model by a relationship between at least one electrical property of the composition, a plurality of physical variables of the composition and said parameter, and measuring a first electrical property of the composition. A sample which is representative for said composition is selected, and a second electrical property of the sample is measured for various magnitudes of at least one of said physical variables. An incoherence function is selected, defining a difference between the measured electrical properties and the electrical properties as calculated from said relationship, said incoherence function being such that independent measurements are weighted in dependence of their accuracy. Said parameter is determined by minimisation of the incoherence function. The first and second property can be the same property.

Abstract: Pertactin (formerly 69 kDa protein) is recovered in stable  biologically  pure  form  having  no  detectable adenylate cyclase activity from fermentation broth from the fermentation of Bordetella pertussis as well as from the cells.  The broth is processed to selectively remove pertussis  toxin  (PT)  and  filamentous  haemagglutinin (FHA),   the  pertactin  is  precipitated  by  ammonium sulphate and the precipitate is dissolved in buffer at pH  6.0  to  8.5,  the  solution  then  is  passed  through hydroxyapatite  and  Q-Sepharose chromatograph  columns before final ultrafiltration.  Cells are extracted with urea and the extract ultrafiltered and diafiltered.  The pertactin  is  precipitated  from  the  extract  and  the precipitate processed as above.   In a variation,  the broth is contacted with ammonium sulphate to precipitate pertactin, PT and FHA, the precipitate is dissolved and the PT and FHA selectively removed, before the solution is passed to the chromatograph columns.

Abstract: A two-part metallic ink composition for intaglio printing is provided which produces bright and shiny ink deposits when printed. The two parts of the ink are stored separately from each other and mixed together either immediately or within a predetermined time period prior to use. The first part comprises varnish in the amount of 60-85%, wax in the amount of 6-15% and solvent in the amount of 6-25%, by weight. These three constituents of the first part are heated together until the wax has just completely melted, stirred and cooled to room temperature. The resultant mixture, which appears physically as a gelled varnish (vehicle), advantageously permits the formulation of a bright metallic intaglio ink without the use of an extender. The second part comprises metallic pigment.      About 1 part by weight of the first part and about 0.5-2.0 parts by weight of the second part are mixed together to form the composition. Preferably, the metallic pigment is prewetted with about 2-4% solvent, so as to form a bread crumb-type consistency, before it is mixed with the first part to prevent dusting (i.e. the escape of pigment into the environment) and to assist in the mixing of the two components. The first part may comprise a drier in the amount of 0.4-2.0% by weight. The particle size of the pigment is preferably less than about 18 microns. To produce the brightest reflective appearance the printed ink composition deposit is heated, immediately following printing, to about 65-75 °C for a period of about one second.

Abstract: The invention concerns a connecting pin (3.2) with which two parts (1 and 2)-for instance, made of a porous material, particularly of wood or similar wood-like material-can be connected and anchored at predetermined anchoring positions (31, 33) in porous material. For this purpose, a bore (42) with a closed end (41) is placed in parts (1 and 2). The form of this bore (42) is adjuste d to the connecting pin (3.2) in such a way that the pin can be guided into the bore without effort and positioned in a first position so that pressure builds up at at least one predetermined anchoring position (31, 33) between the connecting p in (3.2) and the wall of the bore (4.2), if the connecting pin (3.2) is forced with a pressing force (F) into a second position deeper into the bore. Energy is directly focused onto the connecting pin so that the thermoplastic synthetic material of the connecting pin (3.2) is plasticized at the predetermined anchoring positions (31, 32). The locally plasticized synthetic material is pressed into the porous material of the parts by applying the local pressure and forms local, macroscopic anchorings (10, 20). The connecting pin (3.2) consists, f or instance, entirely of a thermoplastic synthetic material, and the energy for plasticizing is gained from the input of ultrasonic vibration .
