Title: Method for manufacturing flexible disks
Inventor: ANDRA RAINER
IPC: F16C7/00
Filed: 1995-10-18
Abstract: Flexible disks contain annular loop packets (10) for the purpose of transmitting traction forces between fastening means (32) . The loop packets (10) and the fastening means (32) are combined to a ring and subsequently embedded in rubber-elastic material. In a preparatory operation the loop packets (10) are injection-coated either individually or in groups by a coating (20, 22) of elastomer material, which defines and stabilizes their outer contour. The elastomer material is only partially vulcanized before the ring is completely embedded in the rubber-elastic material. Injection coating renders the loop packets or groups of loop packets to components which are true to shape and size with defined wall thicknesses. Consequently, the characteristics and the life of the flexible disks are standardized for mass production and the material consumption is reduced.

Title: Stable, reduced permeability papermaker's fabrics containing fibers withfins designed to distort at lower force levels by having a reduced crosssectional area within the fin
Inventor: BOWEN DAVID JR
IPC: D21F7/08
Filed: 1995-09-11
Abstract: A woven or spiral papermaker's or industrial fabric characterized in that at least a portion of its fibers have two or more thin fins, some of which fins are designed for ease of flexing or compression by incorporation of a reduced cross section "hinge" area or by a variation in thickness of more than 20 per cent as a function of distance from the fiber center. This will achieve interlocking between crossing fibers at significantly reduced "beat-up" force in weaving or less shrinkage force in spiral fabrics. By remaining extended where there is no fiber to fiber crushing action, the fins fill the fabric interstitial spaces and control fabric porosity. Significant cost and quality benefits are achieved.

Title: Stabilisateur de temperature de carburant pour moteurs refroidis a l'eau
Inventor: BEAUDOIN LUC
IPC: F02M31/14
Filed: 1997-12-09
Abstract: Dans le domaine de l'automobile, il existe présentement aucun appareil et/ou mécanisme intégré, standard ou non, permettant, en toutes saisons, d'assurer au carburant une température relativement élevée, sécuritaire et constante durant les périodes de fonctionnement du moteur, en vue d'une explosion interne idéale assurant à la fois une combustion plus complète du carburant ainsi qu'une forte et constante puissance. Dans la présente invention, un tel appareil/mécanisme est possible et ce, en modifiant/adaptant simplement un accessoire depuis longtemps en "équipement standard" pour tous les moteurs refroidis à l'eau, le boyau de relais, en caoutchouc ou polymères, servant à acheminer l'eau de refroidissement du moteur vers le radiateur, appelé communément "hose à radiateur" et, précisément celui de la partie supérieure du moteur. Il s'agit donc de joindre audit boyau, sur + ou - 85% de sa longueur, un capteur d'énergie calorifique, en l'occurence une tubulure cuivrée non rigide, disposé en spirale dans les interstices d' un boyau de relais en caoutchouc ou polymères de type "accordéon". L'ensemble est recouvert et protégé par deux matériaux isolants appropriés et, en sus, une enveloppe hermétique en polymères flexibles. Les deux extrémités du capteur de chaleur constituent l'entrée et la sortie du carburant et sont solidement raccordées respectivement, à la sortie de la pompe à carburant et à l'entrée au carburateur. La section d'entrée du carburant comporte un double filtreur de particules amovible ainsi qu'une valve spéciale; elle se reconnait aussi au diamètre plus grand de sa tubulure que celui de la sortie. (Dans le cas des systèmes à injection un adapteur spécial relié à la ligne principale d'approvisionnement en carburant ainsi qu'une tuyauterie appropriée sont nécessaires.)

Title: Method for extending pigments
Inventor: BAUER CARL J
IPC: C09D7/61
Filed: 1996-09-27
Abstract: Unusually high loading levels of smectite minerals are found to provide excellent pigment spacing in aqueous-based coatings, as will enable desired improved hiding, thereby extending the pigment. The level of smectite used in accordance with the invention is sufficiently high that the high gelling efficiency smectites previously used as thixotropes would be inappropriate, and would yield viscosities so high as to render the aqueous coating composition lacking in desired flowability properties. Thus in accordance with the present invention, there is mixed with the aqueous carrier and pigment at least 0.5 % by weight of the total composition, of a particulate water swellable smectite which has a gelling efficiency such as to display a 20 rpm Brookfield viscosity of less than 900 cps when subjected to the standard gelling test herein, with the amount of the smectite in the composition not exceeding that which would raise the viscosity of the composition above 110 Krebs Units (KU).
