Patent CA-2181028-C (CA)
Inventor: SCHAPIRA JOSEPH
IPC: A01N25/14
Filed: 1996-07-11
Granted: 2003-10-28
Abstract: The invention relates to a new solid storage and marketing presentation for phytosanitary compositions based on any active substance which is little soluble in water or insoluble in water and solid at ambient temperature, these active substances are especially selected from herbicides presenting the said features: these herbicides comprise bromoxynil, ioxynil and their esters as well as dinitroanilines, especially butraline, pendimethaline, flumetraline and oryzalin.           It is in the form of flake based on a film-forming material which is water-soluble and brittle after drying, and throughout which are dispersed especially the particles of active material.           This solid storage and marketing presentation may be prepared by means of an installation comprising a rotating drying drum (1) on which a thin layer of a dispersion solution of particles of active substance in an aqueous solution of a film-forming material which is brittle at the dry state is applied.            The parties of the surface of the drum on which is applied the dispersion (D) travel through the heated part or zone of the chamber (2) at a speed such that the dispersion is dried, shrinks and becomes detached fromthe surface of the drum (1) in forming flakes (P).

Title: Reseau polyedre de transducteurs directionnels
Inventor: KUHN PHILIP MORITZ
IPC: G10K11/00
Filed: 1995-01-23
Granted: 2000-03-28
Abstract: Chacun des (éléments) transducteurs acoustiques d'un réseau possède une dimension maximale inférieure à .lambda.. Ils sont situés aux sommets (4, 6) d'un polyèdre régulier (14), qui peut être un icosaèdre (12 éléments), ou un dodécaèdre (20 éléments). Ce placement permet de positionner les éléments sur la surface d'une sphère dont le diamètre a été choisi pour obtenir un espacement entre les éléments compris entre .lambda./3 et 2.lambda./3. Les signaux sont retardés pour la mise en phase afin de former des "faisceaux" directeurs. Un second réseau comprend des éléments placés aux sommets (6, 34) d'un polyèdre (600A) plus petit centré au même point et inclus dans le premier réseau, et dont la fréquence de fonctionnement est supérieure à celle du réseau extérieur. Afin de réduire les effets d'ombrage, les emplacements des transducteurs du réseau (600A) plus petit incorporé sont choisis de sorte qu'ils se trouvent sur des radiales (630) passant par les centroïdes (614) des faces du polygone définissant le grand réseau (14).

Abstract: A  brake monitoring device for railroad cars is provided with a first comparison means which compares the electrical brake power equivalent signal with a first standard value, judges whether or not electrical brake power is generated and closes the locomotive brake deficit check circuit with an interlock means when such electrical brake power equivalent signal is smaller than such first standard value and which opens the locomotive brake deficit check circuit when it is larger.  Such brake monitoring device also includes a second comparison means which compares the electrical brake power equivalent signal with a second standard value which judges whether or not electrical brake power is supplied to the brake power of the trailer car.  Such device closes the trailer car brake deficit check circuit with such interlock means when the electrical brake power equivalent signal is smaller than the second standard value and opens the trailer car brake deficit check circuit when it is larger.  Thus, in cases where brake power is not supplied to the trailer car, even if brake power is generated, it is still possible to greatly improve the safety and simplicity of the delayed-action control brake device.

Granted: 2009-01-27
Abstract: Filtering means include a non-adaptive feedback filter (12) generating active framework vibration control without generating instability in a first frequency band, as well as an adaptive feedforward filter (130). The feedforward filtering coefficients (140) are adapted in real time according to an algorithm selected in order to minimise the energy of the vibration sensed by sensor means (8), depending on the energy of the vibration sensed by the sensor means (100) and the previously measured transfer function in the presence of the feedback filter means and in the absence of the feedforward filter means, between actuating means (10) and the first sensor means (8). The device is used to linearise feedback control throughout a second frequency band broader than the first, to accelerate the convergence of the minimising algorithm, and to improve the strength of the feedforward filter.

Abstract: L'invention concerne une cavité glénoïde artificielle vissable de l'articulation de la hanche (16) pourvue d'un filet spécial (22-26) et destinée à être implantée chez un être humain. Les cavités glénoïdes de ce type sont normalement pourvues d'un filet rectangulaire à dents à flancs parallèles ou d'un filet triangulaire à dents ayant une position neutre, le pas axial étant généralement constant. Ces modes de réalisation sont toutefois défavorables car ils ne tiennent pas suffisamment compte des forces qui s'exercent aussi bien pendant l'implantation que pendant l'utilisation, ou provoquent une destruction inutilement étendue du lit osseux au cas où l'implant devrait être extrait. L'invention optimise le filet (22-26) de la cavité glénoïde vissable, mettant en oeuvre le profil du filet, la position angulaire des dents du filet (22-26) et un pas non linéaire pour assurer un vissage sans effort, une assise stable à long terme et une extraction sans problèmes.

Abstract: A  fuel  burning  system  comprises  a  burner  in communication with a burner supply pipe having an automatic two-stage regulator valve for controlling the pressure of fuel gas delivered to the burner.  The burner supply pipe is  normally  fed by a primary supply pipe delivering collected digester or landfill gas through an automatic three-way valve, however a secondary supply pipe carrying natural gas may be selected by the three-way valve for communication with the burner supply pipe.  The regulator valve and three-way valve are electrically connected to a standard ignition module by a pressure-sensitive switch to detect the presence of digester or landfill gas in the primary supply pipe.  When sufficient gas pressure exists in the primary supply pipe, the three-way valve is operated to permit delivery of the digester or landfill gas to the burner supply pipe and the regulator valve is held in its high stage setting for burning this primary fuel.  When sufficient gas pressure is not present in the primary supply pipe, the three-way valve enables communication of natural gas between the secondary supply pipe and the burner supply pipe, and the regulator valve is held in its low stage setting for burning this secondary fuel.   An alternative embodiment is disclosed wherein the three-way valve is replaced by a pair of automatic gas valves in the primary and secondary supply pipes, respectively.
