Title: Medium consistency pulp ozone bleaching
Inventor: PHILLIPS JOSEPH R
IPC: D21C9/153
Filed: 1991-12-13
Abstract: Medium consistency (e.g. about 6-15%) paper pulp (from 38) is effectively bleached with ozone (from 16) in a carrier gas (typically oxygen) by effecting efficient separation of carrier gas from the pulp after reaction with the ozone, and introducing the ozone into the pulp at a pressure of about 10-13 bar. Ozone in oxygen and medium consistency paper pulp are fed to a fluidizing mixer (12); the intimate uniform mixture produced is then passed upwardly in a reaction vessel (17) until about 99% of the ozone has been consumed, and then separation of gas from the pulp is initiated by moving the pulp mixture into a generally horizontal tube (21) leading to a gas zone in a large diameter retention vessel (22). A pressurized gas pad (26) is maintained at and above the introduction of the pulp into the retention vessel, while the level (29) of pulp in the retention vessel is maintained below the point of introduction. The pulp may be withdrawn from the retention vessel with a fluidizing degassing pump (32), and the pressurized gas removed from the top of the vessel (through 35) may be fed to an apparatus (61) using oxygen gas under pressure. <IMAGE>   <IMAGE>

Abstract: In the technical field of known cardholders for devices such as cards with magnetic stripes on which is encoded informa-tion and/or data in the form of patterns of magnetism, the known cardholders offer no method of 'keeping' (in magnetism ter-minology) the magnetic patterns. The present invention is characterised by incorporating into the cardholders, keepers (1) in the form of sheets of magnetically soft ferromagnetic material with high resistance. The benefit of the invention is obtained when de-vices are placed with the reading surface of their magnetized stripes in close contact with the surface of the ferromagnetic materi-al which, making use of known properties of the material, then acts as keeper of the magnetic patterns.

Title: Sample Collection and Inlet Systems for Gas Chromatography Apparatus
Inventor: SACKS RICHARD D
IPC: G01N1/40
Filed: 1992-06-05
Abstract: A gas chromatography system of the type incorporating a thermal focusing chamber for introducing a sample into a column for separation and analysis.  The system of the present invention provides benefits in terms of reducing memory effect of one analysis being influenced by prior experiments, a reduction in system dead volume which leads to broadening of peaks produced on the chromatogram and artifacts caused by sample decomposition. These advantages are achieved principally through a novel fluid circuit in which the sample is trapped onto the column by trapping it at the end of the thermal focusing chamber closest to the column.  This feature has the effect of eliminating the necessity of the sample residing in the heated focusing chamber for a period giving rise to sample decomposition.  This system further avoids the necessity of passing the inlet flow through mechanical valves which also contributes to memory effect.  This system further has the benefit of enabling sampling of sources at various pressures including ambient pressure as an air quality sensing probe.  An alternative embodiment is a simplified system for  enabling  ambient  pressure  source  monitoring  without mechanical valves in the sample flow path.
