Patent CA-2436930-A1 (CA)
Title: Low energy consumption rf telemetry control for an implantable medical device
Inventor: HAUBRICH GREGORY J
IPC: A61N1/36
Filed: 2001-11-08
Abstract: A frequency synthesizer of an IMD functions in a PLL LOCK mode. The VCO frequency is governed by the PLL and an energy saving HOLD mode. The VCO generated carrier frequency can drift over time. The PLL is coupled with a control voltage of the VCO to develop a frequency control voltage during initial LOCK portions of telemetry transmission. The carrier frequency is modulated during uplink transmission of patient data. An AFC algorithm deriv es a frequency correction value from the difference in frequency of the constan t received carrier frequency and the drifting VCO generated carrier frequency. A frequency correction value is applied to the VCO FM input. A recharge curren t is also applied to the capacitive loop filter.

Inventor: MONEREAU CHRISTIAN
IPC: C01B32/40
Filed: 2002-11-20
Abstract: The gas mixture comprises at least a main constituent to be produced and impurities to be separated from said mixture. The treatment method consists in using at least two adsorbers which follow in offset manner a common cycle during which there are successively an adsorption phase and a regeneration phase using a regenerating gas. Furthermore, it consists in subjecting at the beginning of the adsorption phase (steps I or IV) and/or at the beginning of the use of regenerating gas (step VI), to only part of the gas mixture flow to be treated, respectively the regenerating gas flow, until said adsorber is saturated, respectively substantially discharged, in at least one of the main constituents to be produced, while maintaining at least another adsorber in adsorption phase. The invention is useful for treating a mixture rich in carbon monoxide and hydrogen.

Title: A method of monitoring the needling of fiber structures in real time, and needling apparatus for implementing the method
Inventor: JEAN ROBERT
IPC: D04H18/00
Filed: 2002-06-05
Abstract: A needled fiber structure (P) is made by stacking fiber plies on a platen (100), by needling the plies as the stack of plies is built up by means of needles (114) driven with reciprocating motion in a direction that extends transversely relative to the plies, and by varying the distance between the platen and an end-of--stroke position of the needles while building up the stack so as to obtain a desired distribution of needling characteristics through the thickness of the fiber structure. The instantaneous force (f) exerted during needle penetration is measured (sensors 108) and a magnitude representative of needling force (F) or penetration energy (E) is evaluated on the basis of the instantaneous force, and the evaluated magnitude (F; E) is verified for compliance with at least one predetermined condition to monitor proper operation of the process or to act on the way the distance between the platen and the end-of-stroke position of the needles is varied.

Title: Carton with overlapped base panels and blank therefor
Inventor: LE BRAS PHILIPPE
IPC: B65D71/00
Filed: 2003-02-07
Abstract: A carton of the wrap-around type has a pair of overlapped base panels (12,20).  One of the bases panels (12) which carries a locking tab (38) overlies a tongue (42) protruding from the end edge of the other base panel (20). The protruding tongue (42) is formed with a complementary locking aperture (40) engaged by the locking tab (38) to secure the overlapped panels (12, 20) together. On either side of the locking tab (38), the said one base panel (12) has a hinged tab (50, 52) protruding from the end edge of that panel. Each of the hinged tabs underlies the end edge (44,46) of the other base panel (20), one on each side of the protruding tongue (42). This 'over and under' arrangement presents less of an externally overlapped edge than is the case of a simple complete overlap and thus mitigates against the base panels being skewed or prized apart leading to tearing and/or dislodgment of the locking means.

Patent CA-2478837-A1 (CA)
Inventor: OLES MARKUS
IPC: B32B9/00
Filed: 2003-02-03
Abstract: The invention relates to calendered sheet articles having surfaces, which have self-cleaning properties, and to a simple method for producing self-cleaning surfaces of this type. The inventive method is very simple by virtue of the fact that it can involve the use of existing tools. Sheet articles made of polymers having a high melting viscosity or sheet articles having a woven fabric core are generally produced by using calenders. The inventive method involves the use of these calenders by applying microparticles to at least one roller of the calender. As the sheets are passed by, these microparticles are transferred thereto while being pressed into the surface of the sheet articles. The inventive method makes it possible to obtain self-cleaning surfaces comprising particles with a fissured structure without having to apply an additional embossed layer or foreign material supporting layer to the sheet articles. The inventive sheet articles can be used, for example, as automotive truck tarpaulins, covering tarpaulins, awnings, sunshading roofs or tent tarpaulins.
