Title: Method for selectively reducing subterranean water permeability
Inventor: HUTCHINS RICHARD D
IPC: C09K8/50
Filed: 1993-06-11
Abstract: Gels containing gas precursors and/or pathways are used to selectively reduce the flow of aqueous fluids with respect to the flow of nonaqueous fluids to enhance the recovery of the non aqueous fluids from subterranean formations. The gels, while stable at reservoir conditions, are also readily degraded by gel degrading agents such as acids and therefore are also employed as fail-safe gels in subterranean gel treatments. In another embodiment, selective permeability is restored to a previously treated well by injecting a gas into the previous treated portions of the subterranean formation to displace any aqueous fluid obstructing the passage of the nonaqueous fluid through the polymer-coated pores or gel.

Title: Ink ribbon economy strategy.
Inventor: BUCKBY STEVEN JOHN
IPC: B41J17/12
Filed: 1994-09-27
Abstract: A method of printing is described which utilises a printing head (11) having a plurality of printing elements each of which is operable to transfer a pixel of print medium from a carrier (12) on to an adjacent substrate. The method comprises the steps of:   a) causing relative movement between the substrate and carrier, and the print head, such that the print head moves relative to an area of the carrier from a start position to an end position whilst utilising some or all of the printing elements to transfer a first set of pixels of print medium from the area of the carrier on to the substrate; b) causing relative movement between the print head and the carrier to replace the print head at the start position; c) causing relative movement between the carrier and the substrate such that fresh substrate is presented adjacent to the area of the carrier, and d) causing relative movement between fresh substrate and the carrier, and the print head, such that the print head moves relative to the area of the carrier again from the start position to the end position whilst utilising some or all of the printing elements, to transfer a second set of pixels from the print medium from the area of the carrier, on to the adjacent fresh substrate.   Preferably a different sub-array of print elements is used for each pass over the same stretch of ribbon. A label printer of the kind in which an ink ribbon and a label strip are both moved in unison past a stationery print head is described, which printer uses the economy strategy. <IMAGE>
