Patent CA-2057652-A1 (CA)
Title: Process for preparing multi-colored dyed polyamide substrates
Inventor: KELLEY LARRY C
IPC: D06P3/87
Filed: 1991-12-13
Abstract: ABSTRACT This is a method for producing multi-colored polyamide dyeings which is particularly useful in the multi-colored dyeing of polyamide carpets.   In this method,  a three-component dyeing system is employed which comprises a fiber reactive dye, an anionic resist and an acid-type dye.  The anionic resist  is a water-soluble,  fiber substantative compound which displaces and/or prevents the fiber-reactive dye form fixing in that portion of the carpet which has been treated with the resist.  The anionic resist, however, will not displace the acid-type dye component nor does it prevent fixation of the acid-type dye component.   The invention may be practised by first printing the polyamide substrate in a predetermined pattern with a printing paste containing the acid-type dye and the anionic resist.  The substrate is then flooded or blotch printed with the fiber reactive dye and steamed to fix the dyes.  Alternatively, the substrate may be first flooded or blotch printed with the fiber reactive dye.   The acid-type dye and anionic resist are then printed on top of the fiber reactive dye. The anionic resist displaces the fiber-reactive dye and the dyes are  fixed by steaming.   The method produce fine distinct color patterns with essentially no blurring or mixing of the colors between the printed and unprinted portions of the substrate.

Patent CA-2061014-A1 (CA)
Title: Process for determining and controlling railroad rail's neutral temperature to prevent track buckling and rail fractures
Inventor: AUSTILL ROBERT J
IPC: G01K5/00
Filed: 1992-02-11
Abstract: ABSTRACT            In order to determine a rail's neutral temperature, the length of an unconstrained piece of steel (or "gage") is compared with a similar length of railroad track rail which is constrained and thereby deflected at most temperatures because of the track structure's tie-in to the earth's surface. The gage represents the length that the counterpart piece of rail would be if it were not constrained by the track's connection to the earth's surface. The difference in length is an analog of an associated rail characteristic, such as the number of degrees that the rail's instantaneous temperature (e.g., in degrees F) is above or below the rail's neutral temperature. Length comparisons are made with precision measuring devices configured to directly read out in conventional units the rail characteristic being considered, such as pounds of force or rail neutral temperature in degrees F.

Patent CA-2064565-A1 (CA)
Title: A device for connecting two tool sections
Inventor: MUNDLEIN WERNER
IPC: B23B31/107
Filed: 1990-08-02
Abstract: A device for connecting two tool parts having a common axis.

Title: Digital amplitude modulation with zero sidebands
Inventor: ANDERSON TERRY M
IPC: H03C1/62
Filed: 1990-09-11
Abstract: A communications method and apparatus for zero sideband amplitude modulation is described. Plural digital representations of sinewaves having different amplitudes but same periods are contained in a read-only memory. Selection between the digital representation of sinewaves having different amplitudes is based upon a digital modulation signal. Switching between the digital representations of sinewaves within the read-only memory is performed only at the zero crossing of the sinewave. The digital representations of the sinewaves are output to a digital to analog convertor to produce an RF amplitude modulated carrier signal with no sidebands.  Since the switching of amplitude occurs at the zero crossing of the carrier, no upper sideband or lower sideband information results. The carrier frequency without sidebands is extremely narrow allowing multiple carriers containing high quality information to be closely spaced within the available communications spectrum. A  many fold increase in the available use of the communications bandwidth is achieved.

Title: Reducing chips to fibers in continuous digesters to facilitate lignin extraction
Inventor: HENRICSON KAJ
IPC: C21C7/00
Filed: 1992-06-01
Abstract: ABSTRACT      A conventional continuous digester is modified to effect alkali extraction of lignin after washing. After washing at the bottom of the digester, the chips are reduced to fibers and then subjected to alkali extraction.  Reduction of fibers takes place by mechanically acting on the chips with a rotating element, and/or by causing the chips to flow through a high speed, turbulent zone for a short period of time.  The extraction zone is provided by an upright conduit within the digester vessel, concentric with it, and having an open bottom spaced above the closed bottom of the digester vessel, and above the rotating element.  The diameter of the lowermost portion of the upright conduit is significantly less than the diameter of the main body of the upright conduit. During alkali extraction, the fibers are maintained under the same pressure as in the digester, at a temperature of greater than about 100°C, and in an alkaline environment (normally just with alkali remaining from digesting).  After alkali extraction the pulp is cooled and then passed through a blow valve adjacent the top of the digester.
