Patent CA-2197812-A1 (CA)
Title: Hydraulic temperature compensated cooler bypass control for an automatic transmission
Inventor: DROSTE TIMOTHY A
IPC: F16H59/72
Filed: 1997-02-18
Abstract: A cooler bypass valve, located in a hydraulic circuit between the discharge side of a torque converter and lubrication circuit, includes a valve spool urged by feedback pressure acting in opposition to the force of a compression spring to a bypass cooling mode position where the converter discharge fluid flow is connected to the lubrication circuit bypassing the oil cooler.  The bypass valve includes a viscosity-sensitive pressure divider, which includes a series arrangement of a laminar orifice and a sharp-edged orifice located between the converter discharge and an oil sump.  As oil temperature increases, flow through the laminar orifice produces a control pressure in opposition to the feedback pressure and additive to a spring force, which combine to move the valve spool to a cooling mode position where substantially all of the converter discharge is directed through the oil cooler.  In a predetermined temperature range, the valve maintains a position where a portion of the converter discharge is directed to the oil cooler, and the residual to the lubrication circuit.

Abstract: Une bande fibreuse se caractérisant par une longueur, une largeur et une épaisseur, contient au moins 50 pour cent environ de fibres alignées dans un sens globalement perpendiculaire à la longueur et à la largeur de la bande. La bande définit une pluralité de creux espacés possédant chacun des parties supérieure et inférieure, chaque creux s'étendant depuis une surface de la bande située au moins à 50 pour cent environ dans l'épaisseur de la bande. La densité d'une partie de la bande définissant la partie inférieure du creux est supérieure à la densité d'une partie de la bande définissant la partie supérieure du creux. La partie de la bande qui définit la partie supérieure du creux peut être sensiblement composée des extrémités terminales des fibres, la partie de la bande qui définit la partie inférieure du creux pouvant quant à elle être constituée sensiblement de fibres continues. La bande fibreuse peut être une bande de nontissé de fusion-soufflage ou une bande de nontissé de fusion-soufflage à bords élastiques. Cette bande fibreuse peut être utilisée comme constituant dans des produits absorbants tels que des couches, des produits pour incontinents et des produits d'hygiène féminine tels que des serviettes hygiéniques et des tampons; des éléments de filtration et autres. Cette bande assure une meilleure distribution du liquide dans le sens de l'alignement des fibres.

Title: Process for the preparation of arylamides of heteroaromatic carboxylic acids
Inventor: RODUIT JEAN-PAUL
IPC: C07B61/00
Filed: 1997-03-12
Abstract: A process is described for the preparation of arylamides of heteroaromatic carboxylic acids of the formula: (see formula I) in which each A n is nitrogen or CR n (n = 1-5), with the proviso that at least one of the ring members is nitrogen and that two nitrogen atoms are not bonded directly to one another; R1 to R5, if present, independently of one another are each hydrogen, C1-4-alkyl or aryl, it also being possible for one of the substituents R1 to R5 to be a group of the formula -OR, in which R is an optionally substituted aromatic or heteroaromatic radical; R6 is hydrogen or C1-4-alkyl; and R7 is an optionally substituted aromatic or heteroaromatic radical. The amides are obtained from the corresponding heteroaromatic halogen compounds, the corresponding aromatic amines and carbon monoxide in the presence of a palladium diphosphine complex as catalyst. Compounds of this class, especially those in which one of the substituents R1 to R5 is an aryloxy group, are important herbicides.

Title: A method to evaluate the hangover period in a speech decoder in discontinuous transmission, and a speech encoder and a transceiver
Inventor: KAPANEN PEKKA
IPC: G10L25/78
Filed: 1996-06-26
Abstract: The invention relates to a method for mutual synchronization of the transmitter's speech encoder and the receiver's speech decoder in a communication system utilizing discontinuous transmitter between the transmitter and the receiver. The discontinuous transmission comprises temporally sequential frame periods of which some periods will contain transmitted frames and some periods contain no transmission; whereby the method contains steps to generate information transmission periods (200) comprising at least one frame and containing information given by a user to said transmitter device, and silence periods (208, 209) having a length of at least one frame period and containing other information than that given by the user. The discontinuous transmission further comprises an irregularly occurring period (T) comprising at least one frame between the information transmission period (200) and the next silence period (208, 209), the irregular period forming a hangover period to determine the information relating to the silence period. In the method according to the invention the number of frame periods is counted in the receiver until a certain moment; the beginning of said silence period (208, 209) is detected; and based on said counted number of frame periods and the beginning of the silence period (208, 209) it is decided whether or not there is a hangover period (T) of said type between said information transmission period (200) and the silence period (208) following the information transmission period.
