Title: Procede servant a commander une chaine de nettoyage chimique de bande d'aluminium
Inventor: SIMPSON STEPHEN D
IPC: C23G3/02
Filed: 2002-03-26
Abstract: On utilise un système automatique afin de commander l'étape de nettoyage d'une chaîne de nettoyage de bande, par exemple, d'une chaîne de nettoyage de bande d'aluminium. Cette chaîne de nettoyage comprend une section de nettoyage chimique et au moins une section de rinçage, une solution de nettoyage étant pulvérisée sur les faces supérieure et inférieure de la bande d'aluminium simultanément à son passage à travers la section de nettoyage. Un contrôleur à logique programmable possède un point de réglage de durée de résidence pour chaque rouleau de feuillard d'aluminium, ce qui permet d'obtenir les conditions normalisées de concentration chimique et de température, ainsi que la durée optimum d'exposition de la bande à la pulvérisation. Le contrôleur reçoit des signaux d'entrée en fonction de la température mesurée et de la concentration de la solution de nettoyage et règle en conséquence la durée de pulvérisation de la solution de nettoyage sur la bande d'aluminium.

Title: Pattern diversity in a microwave digital radio system utilizing a single horn reflector antenna
Inventor: NOERPEL ANTHONY R
IPC: H01Q25/04
Filed: 1989-11-28
Abstract: Abstract of the Disclosure During multipath fading in a terrestrial digital radio system, off-axis arrival of signals excites higher-order modes in a horn reflector antenna. In the disclosed system, specified ones of these higher-order modes and the fundamental mode are allowed to propagate in a main waveguide connected to the antenna. At least one of the higher-order modes is abstracted from the main waveguide and fed to a standby receiver while the fundamental mode is propagated intact to a main receiver. Error occurrences in the fundamental and higher-order modes due to multipath fading are substantially uncorrelated. Hence, upon detecting an error in the signals delivered to the main receiver, the system switches to the standby receiver thereby to provide in a single-antenna system a significant improvement in performance against multipath fading.
Patent CA-2007100-A1 (CA)
IPC: F16B2/20
Filed: 1990-01-04
Abstract: An expandible annular elastic strap has a circumferentially slotted first end portion, a tongue-like second end portion which extends into the slot of the first end portion, and an intermediate portion composed of an outwardly projecting circumferentially extending median section and two marginal sections which flank the median section.  The width of each marginal section need not exceed and can be less than half the width of the second end portion, and the three sections of the intcermediate portion of the strap extend all the way from the first to the second end portion.  The median section of the intermediate portion can be provided with one or more circumferentially extending slots which taper in opposite directions.  The median section reduces the area of contact between the external surface of a clamped hose and the intermediate portion of the strap.  In addition, the median section increases the moment of resistance of the intermediate portion and thus contributes to more uniform distribution of clamping force all the way around the clamped portion of a hose which is to be maintained in sealing engagement with the external surface of a nipple or pipe.

Title: Induction coil driver
Inventor: DOANY ZIYAD H
IPC: H04B5/00
Filed: 1990-01-24
Abstract: F.N. 43870 CAN 1A     Abstract of the Disclosure An amplifier which has special application as an induction coil driver.  A multi-frequency signal is used to modulate the pulse width of a square wave, resulting in a pulse modulated signal.  The pulse modulated signal is divided into two delay signals.  The falling edge of each pulse is delayed in one of the delay signals, while the rising edge of each pulse is delayed in the other delay signal.  This creates a "dead band" between the two signals for each pulse.  The signals are used to drive two metal oxide semiconducting field-effect transistors, which are connected to positive and negative power supplies.  The switching of the MOSFETs occurs during the dead band which, when combined with a novel inductor-diode circuit, results in high-efficiency power transfer.  The amplified modulated signal is then subjected to a low-pass filter which cancels out the square wave carrier and switching noise.  The amplified analog signal may then be applied to a non-tuned induction coil.

Title: Projectile empennage deployant system
Inventor: BAUBRY BERNARD H
IPC: F42B10/20
Filed: 1990-03-23
Abstract: According to the invention, the system should reliably provide for the complete and irreversible unfolding of the fins of the tail unit, after the departure of the projectile, and should enable the triggering, after the locking of the fins, of an ignition device for the propulsion unit contained in the projectile. A system for opening an unfolding tail unit for projectiles provided with a propulsion unit, formed by a plurality of fins hinged on shafts and distributed around the projectile, comprises a part capable of sliding imperviously from a first position to a second position in a first bore, so as to drive means for pivoting the fins. With the first bore, this part defines a first chamber and can be shifted by gas pressure in this chamber, generated by a gas generator, the fins being completely unfolded during the shifting of the part towards the second position. The opening system also includes a closing means fixed to the sliding part making it possible, before it has reached the second position, to isolate the first chamber from a second chamber and prevent the triggering of an ignition device for the propulsion unit under the effect of a pressure.

Patent CA-2029312-A1 (CA)
Inventor: CULLICK ALVIN S
IPC: E21B43/243
Filed: 1990-11-05
Abstract: A process is described to direct heat towards a productive interval of a reservoir during a thermal enhanced oil recovery (EOR) operation.  A chemical composition suitable for producing a rigid polymer foam is injected above or below the productive interval.  Once in place the temperature of the composition is increased and it reacts to produce a foamed polymer thermal barrier.  The temperature can be increased by steam injection or in-situ combustion.  After a rigid foam is formed, thermal efficiency is increased by reducing heat losses to non-producing zones during a thermal stimulation.
