Patent CA-2094119-A1 (CA)
Title: Surfaces polymeriques fluorees
Inventor: PATON DUNCAN M
IPC: C08J7/04
Filed: 1991-12-09
Abstract: Des surfaces de polymères, en particulier de polyesters, peuvent être fluorées au moyen du dépôt d'un fluorocarbone sous forme de solution. Le fluorocarbone peut se composer d'un fluoropolymère amorphe, tel que le copolymère de tétrafluoréthylène et de bis-2,2-trifluorométhyle-4,5-difluoro-1,2-dioxyde commercialisé sous la marque déposée TEFLON AF R, soluble dans des alcanes fluorés et d'autres liquides fluorés tels que ceux commercialisés sous la marque déposée FLUORINERT R. Des polyesters à surface fluorées, en particulier sous forme de tissus tricotés, sont utiles comme greffes vasculaires: la surface fluorée réduit les effets thrombogènes et l'activation du système complémentaire. Les inconvénients des procédés de fluoration de surfaces connus, tels que les procédés à plasma froid ou à décharge luminescente, sont ainsi évités.
Patent CA-2094228-A1 (CA)
Inventor: HIRASHIMA MASAYOSHI
IPC: H04N7/169
Filed: 1993-04-16
Abstract: A scramble codec comprises a nonvolatile key data memory which holds a key data varying from one video recorder to another, a pair of line memories in which input picture signals are alternatively written for each horizontal scan line, a nonlinear feedback shift register which is initialized with the output of the key data memory to output dissimilar pseudorandum pulse signals for respective horizontal scan lines, an address setting circuit which sets, as the initial value for scrambling, a value corresponding to the output of the nonlinear feedback shift register and, as the initial value for descrambling, a value obtained by subtracting the output of the nonlinear feedback shift register from the maximum address value of each line memory and an address counter which generates a consecutive series of addresses beginning with the address set by the above address setting circuit and applies a signal for each horizontal scan line alternately to the pair of line memories.

Title: Bead calculator educational toy
Inventor: TAN DARAVUTH
IPC: G06C1/00
Filed: 1993-05-04
Abstract: ABSTRACT OF THE DISCLOSURE    An educational toy useable to teach elementary mathematics to children includes a spaced series of mutually aligned parallel rods secured in a side-by-side relationship at their opposite ends to a base portion of the toy.  Series of counting beads are captively and slidably mounted on all but two of the rods for movement between their opposite end portions.  The remaining two rods, each of which has at least one counting bead rod on each of its opposite sides, slidably carry two operational sign beads having convex polygonal  cross-sections.    Different  equation  operation  sign indicia are suitably positioned on the flat exterior side surfaces of the sign beads such that they can be rotated about their rods to display  selected operational  signs  to  the  user  of  the  toy.          Opposite end faces on each of the sign beads are recessed to nonrotatably receive projecting boss portions of the base at the opposite ends of the sign bead rods, thereby permitting the sign beads to be releasably locked against rotation away from their selected sign display orientations.  By sliding the two sign beads and appropriate groups of the counting beads onto the same end portions of their associated rods, and rotatably adjusting the sign beads, a variety of simple mathematical equations can quickly and easily be represented by the beads in a form easily understood by a child.

Title: Method of brazing metal surfaces
Inventor: TIMSIT ROLAND S
IPC: B23K35/363
Filed: 1992-01-24
Abstract: A novel method is described for joining aluminum to metal surfaces by brazing. The method comprises (a) applying as a coating to at least one of the metal surfaces to be joined a mixture of a metal (e.g. Si, Cu or Ge) and a brazing flux, the metal of the mixture being adapted to form a brazable eutectic with one or both of the surface metals, (b) heating the surfaces and the coating in juxtaposed relation to a temperature above the brazing alloy melting point to thereby dissolve oxide film on the surfaces to be joined, cause the metal of the coating to dissolve into the oxide-free aluminum surface and form therewith a brazing alloy layer and form a brazed assembly and (c) cooling the brazed assembly to form a solidified joint between the surfaces. This has the advantage of providing for the joining of metal surfaces, such as aluminum, to aluminium, cooper, brass or steel surfaces, by brazing without the prior formation of a brazing alloy cladding on the surfaces to be brazed.

Patent CA-2100746-A1 (CA)
Title: Method and facility for time/voltage conversion
Inventor: MAIER MICHAEL
IPC: H03K9/08
Filed: 1992-02-01
Abstract: A more accurate voltage-to-time and then time-to-voltage conversion is accomplished by tailoring the amplitude versus time characteristics of the pulses generated in the voltage-to-time conversion. One embodiment includes applying a ramped voltage supply to an amplifier coupled between the voltage/time converter and the time/voltage converter. The ramped supply is arranged to condition the amplitude of a portion of respective pulses to include a slope similar to the ramped voltage applied to the time/voltage converter. This tends to effect a more accurate response in the time/voltage converter.
Patent CA-2101766-A1 (CA)
Inventor: GERBER ARTHUR H
IPC: C08L61/06
Filed: 1993-08-02
Abstract: Compositions containing aryl phosphites and water to hydrolyze the aryl phosphite provide controlled and extended work time when used as hardening agents for the ambient temperature hardening of phenolic resins and for rapid hardening of such resins at modestly elevated temperatures.   Pre-solvolysis with small quantities of water, alkanols of 1 to 4 carbon atoms or alkylene glycols of 2 to 4 carbon atoms improve compatibility of trisubstituted phosphites with the resin.   Pre-hydrolysis of the phosphites as well as addition of furfuryl alcohol or alkylene glycols of 2 to 4 carbon atoms accelerate the hardening (curing) of the resin.   Various compounds such as: carboxylic acid amides, urea, dicyandiamide, N-methylolated amides, N-alkyl 2-pyrrolidinones having 1 to 4 carbon atoms in the alkyl group, those having an internal epoxide group, alkanols, and Schiff bases retard the ambient temperature hardening of the resin with the aryl phosphite hardening agents.
