Title: Apparatus and method for assessing the geophysical characteristics of a core sample
Inventor: JACKSON PETER D
IPC: G01N27/04
Filed: 1991-05-07
Abstract: Apparatus for assessing geophysical characteristics by measuring resistivity of a core sample comprises a first array (C1) of current electrodes, a second array (C2) of current electrodes, a constant current source and sink to pass constant current between the electrodes in the arrays (C1, C2), control means supplying substantially equal currents at each of the electrodes and second control means to ensure that the current received by the electrodes (C2) is substantially equally distributed between them. The illustrative apparatus further comprises a third array (P1-64) of potential electrodes adapted to be positioned at spaced intervals on a sample to be assessed. Computer records the results and controls operation of the illustrative apparatus.
Patent CA-2083106-A1 (CA)
Inventor: MEIER JACQUES
IPC: B42B4/02
Filed: 1992-11-17
Abstract: The stitching or stapling heads, which act together in a stitching zone (C) with the supports that carry printed products to be wire-stitched, have a circular orbit.  The stitching heads are guided so as to maintain their more or less vertical position during their orbit.  Within the stitching zone  (C),   each   stitching   head  is  thus approximately aligned with its respective support and is therefore in  the   preferred   position for driving the staples into the printed products.   When the stitching heads encounter the supports, they   are pushed back radially inward against the resistance of  compression springs.   This causes a slight flattening in the orbit of the stitching heads in the stitching zone (C) and slightly prolongs the time available for the stitching heads to act together with the  supports in the stitching process.

Title: Flocked fabric printing
Inventor: BLANTON G KELLY
IPC: D06P1/54
Filed: 1992-05-20
Abstract: A flocked fabric has colors with long wearing capabilities and includes a textile substrate and raised disperse-dyeable fib-ers adhered to the substrate, an opaque particulate colorant adhering to the raised fibers and arrayed on the fabric in a printed pattern. A dye other than the opaque particulate colorant is also arrayed on the fabric in other portions of the printed pattern, such as in a blotch. A melamine-latex binder system causes the opaque particulate material to adhere to the fibers, and a resist causes the other dye not to dye the fibers in the area of the malamine-latex binder system. The opaque particulate colorant is ad-hered to the fibers strongly enough to show only very little wear after 15,000 cycles on a Wyzenbeek abrasion test.
