Title: Matieres ligno-cellulosiques stables au traitement et a la lumiere et leur production
Inventor: WILLIAMS TREVOR
IPC: D21C9/16
Filed: 2003-10-21
Abstract: L'invention concerne un nouveau procédé destiné à la production de matières ligno-cellulosiques stables au traitement et à la lumière, et notamment à la production de pâtes de bois mécaniques présentant une stabilité au traitement et à la lumière accrue. L'invention concerne également des pâtes résultantes présentant une stabilité au traitement et à la lumière accrue ainsi que des papiers contenant ces pâtes. Ce nouveau procédé consiste à faire réagir des matières ligno-cellulosiques, telles que des pâtes chimio-thermomécaniques blanchies (BCTMP) avec (a) un inhibiteur de jaunissement réactif aux fibres et soluble dans l'eau possédant deux ou plusieurs groupes fonctionnels amino ou ammonium secondaire (-NHR' ou  HN+HR'), amino ou ammonium tertiaire (-NR'R'' ou -HN+R'R''), et/ou ammonium quaternaire (-N+R'R''R''') dans un milieu aqueux, ou (b) un photostabilisant à amine encombrée réactif aux fibres et soluble dans l'eau possédant lesdits groupes fonctionnels amino ou ammonium dans un milieu de blanchiment au peroxyde alcalin ou dans un milieu aqueux avec blanchiment subséquent des matières dans un milieu de blanchiment au peroxyde alcalin. Par exemple, les inhibiteurs de jaunissement réactifs aux fibres et solubles dans l'eau peuvent se présenter sous la forme d'une nouvelle N-(2,2,6,6-tétraméthyl-1-oxyl-pipéridin-4-yl)-N'-{2-[2-(2,2,6,6-tétraméthyl-1-oxyl-pipéridin-4-ylamino)-éthylamino]-éthyl}-éthane-1,2-diamine (dont l'abréviation est TETA-2TAMPO) et de son dérivé hydrochlorure d'hydroxylamine, soit l'hexahydrochlorure de N-(2,2,6,6-tétraméthyl-1-hydroxyl-pipéridin-4-yl)-N'-{2-[2-(2,2,6,6-tétraméthyl-1-hydroxyl-pipéridin-4-ylamino)-éthylamino]-éthyl}-éthane-1,2-diamine (dont l'abréviation est TETA-2TEMPOH-6HCl).

Patent CA-2007165-A1 (CA)
Inventor: SCHERER RICHARD J
IPC: H01R4/24
Filed: 1990-01-04
Abstract: In electrical terminals it is sometimes necessary to insert two wires into a contact adapted for insulation displacement connection and to do so successfully the wires must enter the wire receiving slot sequentially. A wire receiving opening aligned with the wire receiving slot should have a generally circular opening to readily receive the wires but when the wires are forced in the direction of the wire receiving slot a semi-circular concavity communicating with the opening and positioned on the side of the opening opposite the slot will receive one wire to feed the wires sequentially.

Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a method for crimping an open end of a can body.   A male die is inserted into the can body through the open end in such a manner as to be coaxial therewith.   Then, the female die is caused to fit on the opening end, and the female die is kept moving along the outer peripheral surface of the male die while moving the male die,  inserted into the can body,  in a releasing direction from the can body.  Thus, the opening end is crimped by the relative movement of the male and female dies.          There is also disclosed a crimping apparatus which includes at least one crimping mechanism, a holder for holding the can body at a prescribed position, a complex cam and a drive mechanism.  The crimping mechanism includes male and female dies, follower members connected to the male and female dies, respectively.   The cam includes first and second cam faces with which the first and second  follower members  are respectively held in engagement.  The drive mechanism is operable to move the first and second followers along the first and second cam faces to move the first and second follower members axially of the male and female dies in a prescribed manner.

Filed: 1990-03-30
Abstract: A clock extractor which generates a clock signal for sampling of a data signal received from a digital line on the basis of a separation clock having a period corresponding to a data communication rate of a data to be separated from the received data signal.  The clock extractor always generates a plurality of clock signals which have respectively an identical period corresponding to a data communication rate of the received data signal and which phases are slightly shifted mutually, and each time selects one of the plurality of clock signals as a clock signal for sampling of the received data signal.  In the selecting operation of the clock extractor, a change in the logical level of the separation clock to a specific level is detected with resolution power corresponding to the slightly mutually shifted phases of the plurality of clock signals, and any one of the plurality of clock signals is specified according to the detection timing.  The clock signal thus specified can be used to most faithfully reproduce the phase of the separation clock and the continuity of the separation clock as a clock signal.
