Title: Tow rope shock absorbing device
Inventor: OSWELL ROBERT
IPC: B63B35/81
Filed: 1999-08-18
Abstract: A shock absorbing device for attaching a tow rope to a boat for the purposes of water sports comprising a bias element attached between a boat and the load end of a tow rope such that when a load sufficient to overcome the biassing force of the bias element is placed on the tow rope the separation between the boat and the load end of the tow rope is increased by a limited distance. The bias element can conveniently be located inside a tow rope pylon, with a cable emerging for attachment of the tow rope. In a simple form, the invention can be a spring in line with a tow rope, with a restricted extension. The invention greatly reduces shock to athletes, and is particularly suited to wakeboarding, as the bias element provides a sling-shot effect which allows for higher jumps than would normally be possible.

Abstract: L'invention concerne la déminéralisation d'une solution de sucre de betterave, cette déminéralisation étant effectuée avant la cuisson de cette solution, utilisée comme solution première, au moyen d'un séparateur en chromatographie à lit mobile simulé comprenant plusieurs colonnes garnies d'une résine échangeurs de cations fortement acide, sous forme saline. Cette résine présente une granulation moyenne variant entre 300 et 500  mu m, ainsi qu'un coefficient d'uniformité d'au moins 1,2 comme garnissage chromatographique (garnissage séparé). Chacune desdites colonnes garnies comprend un orifice d'alimentation pour solution première, un orifice d'alimentation pour éluant, un orifice d'évacuation pour une fraction de constituant présentant une forte affinité vis-à-vis du garnissage chromatographique (constituant "à forte affinité"), et un orifice d'évacuation pour une fraction de constituant présentant une affinité faible vis-à-vis du garnissage chromatographique (constituant "à faible affinité"). On utilise plusieurs pompes de circulation, dont la quantité est au moins égale à la moitié du nombre de colonnes garnies, la solution de sucre de betterave étant déminéralisée avant d'être cuite selon les conditions suivantes: le rapport volumétrique de la vitesse d'alimentation de la solution première à la vitesse d'alimentation de l'éluant varie entre 1/2,5 et 1/3,5; le rapport volumétrique de la vitesse d'évacuation de la fraction du constituant à forte affinité à la vitesse d'évacuation de la fraction du constituant à faible affinité se situe entre 0,5/1 et 1,2/1; et le taux de circulation atteint 25 à 80 vol. %/h., en fonction du garnissage chromatographique dans une zone du système de circulation dont la vitesse d'écoulement est inférieure. On peut ainsi obtenir une fraction de saccharose avec une concentration en saccharose élevée, grâce à une faible quantité d'éluant à débit élevé.

Abstract: La présente invention concerne un revêtement pour articles biodégradables comprenant un revêtement pouvant être hydraté ou un revêtement présentant une discontinuité chimique ou physique. Les imperfections du revêtement, qui peuvent comprendre des pores dans le revêtement, permettent à l'eau de pénétrer jusqu'à la surface sous-jacente de l'article hydrosoluble. La nature et l'étendue des imperfections permettent de réguler la vitesse de pénétration de l'eau dans le revêtement. Dans un autre mode de réalisation, le revêtement est un revêtement pouvant être hydraté qui gonfle et se déchire lorsqu'il est hydraté afin d'exposer l'article sous-jacent à l'humidité. La présente invention permet de protéger l'article d'une dissolution prématurée au cours de sa durée de vie normale, article qui se dégradera cependant lorsqu'il sera éliminé avec les déchets et que le revêtement de surface, en se dégradant, permettra à l'eau d'atteindre et de dissoudre l'article sous-jacent. En général, le corps de l'article comprend un poly(alcool de vinyle) ou un copolymère poly(alcool de vinyle)/poly(acétate de vinyle) hydrosoluble biodégradable. On peut former la discontinuité chimique/physique en recouvrant d'un revêtement pouvant être hydraté une surface déjà couverte d'un revêtement comportant des défectuosités physiques.

Abstract: Proactive robust threshold schemes are presented for general "homomorphictype" public key systems, as well as optimized systems for the RSA function. Proactive security employs dynamic memory refreshing and enables us to tolerate a "mobile adversary" that dynamically corrupts the components of the systems (perhaps all of them) as long as the number of corruptions (faults) is bounded within a time period. The systems are optimal-resilience. Namely they withstand any corruption of minority of servers at any time-period by an active (malicious) adversary (i.e., any subset less than half. Also disclosed are general optimal-resilience public key systems which are "robust threshold" schemes (against stationary adversary), and are extended to "proactive" systems (against the mobile one). The added advantage of proactivization in practical situations is the fact that, in a long-lived threshold system, an adversary has a long time (e.g., years) to break into any t out of the l servers. In contrast, the adversary in a proactive systems has only a short period of time (e.g., a week) to break into any t servers. The model of mobile adversary seems to be crucial to such "long-lived" systems that are expected to span the secure network and electronic commerce infrastructure.

Title: Air brakes for trucks
Inventor: HUNTER MARC
IPC: F16D65/14
Filed: 2000-06-08
Abstract: The present invention provides an improvement in an actuator system for use with a brake system of the type including a brake and a source of compressed air which is connected to an air chamber including a push rod for moving a transverse brake actuator bar between a brake applied position and a brake released position. The push rod operates the transverse brake actuator bar. The actuator system includes an asymmetric operator member which is relatively-rotatably-attached to a non-rotatable wheel support, and which is concentrically-disposed around an axle of a wheel. The asymmetric operator member includes an ear which is attached to the transverse brake actuator bar. A  brake arm assembly includes a pair of diametrically-opposed arcuate brake arms, each brake arm including an inner arcuate channel member, one end of the arcuate channel member terminating in a hollow cylindrical bushing, the other end of the channel member terminating in a pair of transversely-spaced-apart ears having aligned apertures therethrough. An inner anchor plate and an outer anchor plate sandwich the asymmetric operator member therebetween and also are relatively-rotatably-attached to the non-rotatable wheel support which is concentrically-disposed around the axle of the wheel. The anchor plates are non-rotatably-secured to the asymmetric operator member. A  first bifurcated link is rotatably-attached between the ears of a first channel member and the anchor plates, and a second bifurcated link is rotatably-attached between the ears of a second channel member and the anchor plates. A first hollow cylindrical bushing is rotatably-attached to the anchor plates opposite to the attachment of the second bifurcated link, and a second hollow cylindrical bushing is rotatably-attached to the anchor plates opposite to the attachment of the first bifurcated link. On activating the air pot, the push rod moves the transverse actuator bar to rotate the asymmetric operator member in a counter-clockwise direction, to urge the arcuate brake arm to move in a braking action radially-outwardly from an inactive position towards, and frictionally-engaging, radially-inwardly-facing brake pads, and on venting compressed air from the air pot, the push rod moves the transverse actuator bar to rotate the asymmetric operator member in a clockwise direction, to urge the arcuate brake arms to move in a brake releasing action radially-inwardly to inactive positions away from, and out of frictional engagement with, the radially-inwardly-facing brake pads.
