Title: Dispositifs electriques
Inventor: ZHANG MICHAEL
IPC: H01C1/14
Filed: 1995-06-09
Abstract: Des dispositifs électriques, en particulier des dispositifs de protection de circuits, contiennent des éléments de polymères conducteurs dont les arêtes sont constituées par fracture de l'élément de polymère conducteur, selon un tracé voulu, sans introduction de corps solide dans l'élément. La rupture cohésive du polymère conducteur produit une surface fracturée distinctive. L'un des procédés de réalisation de ces dispositifs consiste à corroder des canaux de fracture dans les électrodes d'une plaque contenant un élément de polymère conducteur à coefficient de température positif, inséré entre des électrodes à film métallique, puis à briser la plaque le long des canaux de fracture afin de former des dispositifs individuels. La figure montre un dispositif de protection de circuits réalisé selon ce procédé.

Patent CA-2211968-A1 (CA)
Inventor: PARKER JEFF P
IPC: A01H5/10
Filed: 1995-12-26
Abstract: L'invention présente un moyen amélioré permettant de produire des semences capables de donner des plantes hybrides F¿1? à partir d'une culture susceptible de connaître une pollinisation croisée tout en faisant appel à l'autostérilité. On utilise une population de pied-mères, mélangée, dans une large mesure, au hasard, se trouvant pratiquement incapable de connaître une auto-pollinisation dans des conditions classiques de croissance et chez qui cette incapacité peut être attribuée, pour chaque pied-mère, à la présence d'au moins un déterminant génétique dominant à l'état hétérozygote pour une autostérilité sporophytique différente chez chacun d'eux. Tous les plants sont en mesure de servir (1) de mères par la semence qui, à la suite d'une pollinisation croisée avec un pollen de l'autre pied-mère, portent des semences capables de donner des plantes hybrides F¿1? d'un cultivar prédéterminé et (2), de mères par le pollen pour d'autres pied-mères. La récolte simultanée non sélective par des procédés classiques chez les deux pied-mères d'une semence capable de donner un unique cultivar prédéterminé d'une plante hybride F¿1? est ainsi rendue possible. Le produit qui en est issu présente une vigueur hybride, ce qui permet au planteur d'obtenir des rendements accrus. Dans un mode de réalisation préféré, la culture en question est le Brassica napus de la variété Canola du colza.

Title: Method and apparatus for treating a video signal
Inventor: FRANKLIN TREVOR
IPC: H04N5/76
Filed: 1996-04-04
Abstract: A method of treating a video signal to allow playing on a video cassette recorder (VCR) but not to allow copying using a VCR having an automatic gain control (AGC) when recording. The method involves inserting one or more pulses (22) into the back porch (45) during the horizontal blanking interval and attenuating the last lines (24) of the picture information portion (16) and horizontal synchronisation information (18) at the end of each alternate frame. The pulses (22) comprise a pulse signal (44) inserted into the colour burst information portion (34), an opposing pulse signal (45) having a magnitude sufficient to offset the change in the dc level of the colour burst portion (34), caused by the pulse signal (44), and a further pulse (50) inserted somewhere from the last half of the remainder of the back porch (45) to the end of the start of the picture information portion (16). Consequently, the dc level of the colour burst information portion (34) is always maintained at the same level as it was prior to the insertion of the pulses (20). A  particular encoder (52) is also disclosed together with a method and apparatus (101) for decoding a video signal treated in the aforementioned manner so as to recover the original video signal.

Abstract: The invention provides a process for gas separation wherein a selected gas in a mixed gas stream is contacted by an enzyme having an active site directly contacted by the mixed gas stream, and the selected gas is at least partially removed from the mixed gas stream. In one embodiment a selected gas in a gas phase is contacted by a solvated enzyme wherein the enzyme active site is in direct contact with the gas phase, and the selected gas is converted to a first product in a condensed phase by contact with the solvated enzyme. The invention also provides a bioreactor which comprises a vessel having at least one first wall enclosing an inlet zone, and at least one second wall enclosing a second phase zone, a portion of the second wall is permeable to at least one selected gas in the inlet zone, and retains the second phase in the second phase zone; a portion of the second wall also comprises a support surface with at least one enzyme fixed thereon, such that a mixed gas stream entering the inlet zone contacts enzyme which removes a selected gas from the mixed gas stream and passes the selected gas to the second phase zone. The invention also provides an alternative bioreactor which comprises buoyant beads coated with enzyme, floating on the surface of a condensed fluid phase, in contact with a gas phase such that the active site of the enzyme is in direct contact with the gas phase, and the beads are free to rotate in response to motion in either phase, and means for producing motion in at least one phase such that portions of the beads alternately contact the gas phase and the fluid phase, bringing a selected gas into the condensed fluid phase.
