Title: Selective call signaling system and method with combined wide area paging and high data rate transmissions via radio telephone transceivers
Inventor: DAVIS WALTER LEE
IPC: H04B5/00
Filed: 1993-11-23
Abstract: A cooperative paging system (10) and radio telephone system (15) combine to provide conventional delivery of short paging messages to a combination pager/radio telephone (40) via a first communication path, while a radio telephone link operating at a higher data rate is used to deliver large data messages to the pager/radio telephone (40). The radio telephone link is formed by a transceiver section (205) of the pager/radio telephone (40) coupling to a radio telephone base station (50,52) and calling up a paging terminal (32) of the paging system (10). The paging terminal (32) retrieves the large data messages from a temporary message memory (42) to deliver to the pager/radio telephone (40).

Title: Wellbore sand control method
Inventor: JONASSON RALPH G
IPC: E21B33/138
Filed: 1995-07-10
Abstract: A slug of solution, comprising a linear polymer (e.g. polysulfone) dissolved in a "good" solvent (e.g. morpholine) is emplaced in the near-wellbore region of an unconsolidated sand reservoir. A second slug comprising a poor solvent for the polymer (e.g. water) is pumped into the region to contact the first slug. The linear polymer is precipitated and forms a three-dimensional network of interconnected strands extending through the fluid flow channels between the sand grains. The network functions to consolidate the sand.

Title: Method of applying veneer to a substrate
Inventor: EWASCHUK WILLIAM JOHN
IPC: B27D1/08
Filed: 1996-05-10
Abstract: The invention provides a method of applying a veneer to a substrate having edges with a compound curve. The invention includes the steps of trimming the veneer to provide a peripheral margin and applying a stretchable releasable adhesive tape to the margin, applying an adhesive to the surfaces of the substrate, positioning the veneer over the substrate and securing the veneer in position, and subjecting the veneer to a substantially uniform pressure over thesubstrate. An embodiment for convex edges provides the further steps of providing one or more v-shaped relief cuts converging where the curved edge surface meets the main surface and applying a releasable adhesive tape to retain a butt joint between the edges of each relief cut. An embodiment for concave edges provides the further steps of providing one or more slits extending into the margin of the veneer parallel to the direction of the grain and applying a releasable adhesive tape over the relief cuts. The invention thus permits a single sheet of veneer to be applied over the main and edge surfaces of furniture and the like having concave or convex rounded or bullnose edges.

Title: Apparatus for determining position of moving body
Inventor: MURAYAMA OSAMU
IPC: G05D1/02
Filed: 1994-12-06
Abstract: The first object is to correct deviation of a guided moving body by dead reckoning before and after a lap in order to precisely guide it.  A second object is to facilitate determination of initial position and initial bearing of a guided moving body by dead reckoning. When the moving body 1 travels on a lane L3, the positions of two reference points R11 and R12 located immediately forward of the start point on the lane L3 are calculated as positions on coordinate axes x-y. When the moving body 1 has completed a lap around lane L3, returned to the starting point Ps, and continues to travel, the positions of the two reference points R11 and R12 are recalculated as R'11 and R'12 on the coordinate axes x-y. Deviations of the position and traveling direction of the moving body 1 when it has completed a lap around the lane L3 are corrected on the basis of the positions of the two reference points so calculated and the estimated position and estimated direction Pe (xe, ye, .theta.e) when the moving body has completed a lap around lane L3 and returned to the starting point Ps.

Filed: 1995-12-27
Abstract: The present invention relates to coating methods and coating apparatus suitable for the stable production of coatings on the flat surface of sheet substrates, and methods for manufacturing coated sheet products such as color filters.      An embodiment of the coating method according to the present invention is a coating method wherein a coating liquid feeder supplies coating liquid to a coating liquid applicator having a coating liquid discharge slot, with at least either the coating liquid applicator or a substrate to be coated being moved relatively one to the other to form a coating with a predetermined thickness on the substrate, comprising the steps of: keeping at rest the substrate at a position where the start-of-coating line of the substrate is in register with the coating liquid discharge slot of the coating liquid applicator; commencing discharge of the coating liquid through the coating liquid discharge slot; forming a coating liquid bead which is in contact with both an exit aperture portion of the coating liquid discharge slot and the start-of-coating line of the substrate; and subsequently commencing movement of at least either the coating liquid feeder or the substrate relatively one to the other.      A coating method of this embodiment makes it possible to accurately determine the start-of-coating line and form a high accuracy coating, because by this method, after discharge of the coating liquid starts while the substrate to be coated is still at rest in register with the coating liquid discharge slot and the formation of the coating liquid bead is assured, the substrate is moved relatively to the coating liquid discharge slot while rendering the coating liquid bead stable.

Title: A method for preparing fine-granuled and modified starches
Inventor: MALKKI YRJOE
IPC: A23L29/30
Filed: 1995-05-30
Abstract: The subject of the invention is a method for preparing fine-granuled starch from kernels of oats or rice. In the method, the kernels are ground and the starch is separated from the starch containing fraction obtained by the milling. An essential feature of the invention is that a suspension of the said fraction or of starch separated from it is treated with a surface-active agent or a lipolytic enzyme for disintegrating compound granules or aggregates of starch granules. Except the particle size, also functional properties of starch are affected. Disintegration of compound granules is enhanced by alkaline conditions and by mixing of the suspension. The fine-granuled starch obtained can be applied in foods and, for instance, for biodegradable plastics and for surface treatment agents. The invention can be included as a part of an integrated fractionation process, in which, in addition to starch, an oil fraction, an enriched fibre fraction, and a surplus fraction suitable for feed, are obtained.
