Title: Textile treatment
Inventor: LEWIS DAVID
IPC: D06P1/642
Filed: 1998-02-19
Abstract: A compound of formula (I) wherein: R1 and R2 each independently represents arylamino, diphenylamino, benzylamino or dibenzylamino, and Z represents a leaving group. In general the group -SO2-CH2-CH2-Z is a blocked vinylsulphone and in some cases it is advantageous to use the free vinylsulphone. The leaving group Z may comprise, for example, sulphato (-OSO3-), S-thiosulphato (SSO3-), Sarcosine, N-methyltaurine, N,N-dialkyl acetate (-O-CO-CH3), acyloxy (O-CO-R, where R is alkyl e,g, C1-C5), phosphato (-OPO-3), or a halogen. Activation of the leaving group is usually by means of heating in slightly acidic baths to produce the fibre reactive vinylsulphone. Alternatively the free reactive vinylsulphone may be pre-formed and applied to the fabric as a dispersion. The compounds of the invention contain more aromatic rings which are not substituted with vinylsulphone groups which has been found to improve pi-bonding. In addition the pi system of the present invention is planar, which has been found to be crucial to increasing the affinity of the fibres to disperse dyes as well as imparting shrink resistance and other properties to the fabric.

Patent CA-2302995-A1 (CA)
IPC: G01V3/38
Filed: 2000-03-24
Abstract: A novel method for measuring fracture porosity in coal seams is disclosed.  Knowledge of fracture porosity is critical to methane production from coal seams as fractures form the main permeable pathways for gas migration. The disclosed invention can be used to determine likely locations where commercially significant amounts of fracturing have occurred in the coals. These locations pose prime targets for methane exploration, and the disclosed invention comprises a significant new tool in methane exploration. The disclosed invention uses existing geophysical well log data, a screening process and calculations based on the characteristics of the fluid used to drill the hole.  Using these data, the volume of invaded coal is determined, as well as the volume of drilling fluid available to create this invasion. The volume fraction of the invading drilling fluid divided by the volume of the invaded rock produces a measure of the fracture porosity of the coal. Locations that exhibit higher values of fracture porosity are more commercially attractive as methane exploration targets.
