Patent CA-2455737-A1 (CA)
Title: Suppressed cycle based carrier modulation using amplitude modulation
Inventor: BOBIER JOSEPH
IPC: H04L27/06
Filed: 2001-10-04
Abstract: A sinusoidal RF carrier is modulated for the transmission of digital binary data streams through the amplitude supression of carrier wavelets, which are defined between zero crossover positions representing zero energy locations. This modulation is accomplished when the carrier is slightly amplitude modulated with a modulation signal that is equal in frequency to the carrier itself and the modulation always begins or ends upon the exact zero voltage crossing point of the RF cycle phase. The modulation is applied as a slight shift of the amplitude of any single cycle, each cycle representing a single bit of data. A single cycle of RF will either represent a "1" or "0" dependi ng upon the amplitude of the cycle, relative to other adjacent cycles in the sa me carrier.

Title: Procede d'augmentation de la souplesse de bandes de base et de produits fabriques a partir de ces dernieres
Inventor: DREW ROBERT A
IPC: D21H27/38
Filed: 2002-11-26
Abstract: L'invention concerne un procédé permettant d'augmenter les propriétés tactiles d'une bande de base sans modifier la résistance de cette dernière. Dans un mode de réalisation, le procédé consiste à placer une bande de base en reliefs entre un premier tapis transporteur mobile et un second tapis transporteur mobile. Les tapis transporteurs sont alors enveloppés autour d'un rouleau à cisaillement qui crée des forces de cisaillement et des forces de compression agissant sur la bande de base. Les forces de cisaillement disloquent la bande, ce qui augmente la souplesse et diminue la rigidité de la bande. Les forces de compression se situent au niveau des zones où les charnières de tissu sont en contact avec la bande de base, ce qui permet de fournir à la bande un motif unique imprimé en tissu à réduction d'épaisseur limitée. Le rouleau à cisaillement présente généralement un petit diamètre. Dans certains modes de réalisation, plusieurs rouleaux à cisaillement peuvent être intégrés au système.

Abstract: Anthrax toxin, comprising of protective antigen (PA), lethal factor (LF) and edema factor (EF) is a major virulent factor of B.anthracis. Protective antigen, PA is the main component of all the vaccines against anthrax. The protective efficacy of PA is greatly increased if small quantities of LF or EF  are incorporated into the vaccines. An ideal vaccine against anthrax should contain PA, LF and EF together, but this combination would be toxic.  Therefore, the biologically inactive mutant preparations of PA, LF and EF may be used together for better immunoprotection. The present invention describes the method for generation of recombinant vaccine against anthrax, comprising of non-toxic, mutant anthrax toxin proteins. The procedure involves site-directed mutagenesis of the native genes of the toxin proteins, the expression and purification of the mutant proteins and finally characterization of these proteins.
