Patent CA-2131510-A1 (CA)
Inventor: MANDELBAUM RICHARD
IPC: H04W12/06
Filed: 1994-09-06
Abstract: Une carte intelligente qui permet à différents fournisseurs de service de coexister sur la carte intelligente sans que les fournisseurs de service, le propriétaire de la carte intelligente aient accès aux fichiers créés pour, ou par, chacun des fournisseurs de service présents. Le système d'exploitation de la carte intelligente comprend un répertoire racine qui appartient à l'émetteur/propriétaire de la carte intelligente et chaque fournisseur de service est un « utilisateur » qui est installé par l'émetteur/titulaire. Chaque tel utilisateur a un sous-répertoire du répertoire racine et, dans le sous-répertoire, l'utilisateur crée des fichiers et des sous-répertoires comportant des fichiers, selon les besoins de l'utilisateur. Le système d'exploitation empêche tous les utilisateurs de la carte intelligente, y compris l'émetteur/titulaire de la carte intelligente et le détenteur de la carte intelligente, d'accéder à tout fichier qui appartient à un autre utilisateur, lorsque l'utilisateur choisit d'empêcher un tel accès. Ce pouvoir d'exclusion est régi par un mot de passe qui appartient à l'utilisateur et qui ne peut pas être modifié par un autre utilisateur, y compris l'émetteur/propriétaire de la carte intelligente. Facultativement, l'émetteur/propriétaire de la carte intelligente a le pouvoir d'effacer tous les fichiers d'un utilisateur donné. La connexion est établie à l'aide d'un protocole qui authentifie toutes les parties de la connexion. Ainsi, dans une connexion entre la carte intelligente et un utilisateur, la carte intelligente détermine si l'utilisateur peut obtenir l'accès et l'utilisateur détermine si la carte intelligente est une carte intelligente valide. L'authentification du traitement de la carte intelligente peut également être établie.

Title: Track-belt for track driven vehicles
Inventor: COURTEMANCHE DENIS
IPC: B62D55/24
Filed: 1994-09-23
Abstract: The invention relates to an improvement in an endless track belt of the type comprising, a body made of an elastomeric material, an outer surface for contact with the ground and an inner surface provided with lugs or openings for engagement with the driving system and at least one endless pathway having a sliding surface contacting a corresponding slide rail of a slide rail suspension. This pathway is devoid of the lugs or openings for engagement with the driving system. The endless sliding surface is provided with a plurality of slide clips that are spaced apart from each other by a segment of the endless sliding surface. This segment is divided in at least a first and a second distinct part. The first part is made of elastomeric material and the second part defines at least one cavity through the body. The improvement is characterized in that the cavity through the body is to allow the introduction of snow between the slide rail and the first part and in that the first part is of such size that friction with the slide rail will generate heat in a sufficient amount to melt the snow and maintain a lubricating film of water therebetween. Such track belts are of a reduced weight but as efficient as common track belts.
Patent CA-2133854-A1 (CA)
Title: Method for cyclic operation of reactors
Inventor: HEISEL MICHEAL
IPC: B01J8/02
Filed: 1994-10-07
Abstract: Method for Cyclic Operation of Reactors Abstract The invention relates to a method for cyclic operation of at least two reactors, with at least one catalytic reaction taking place in reactors traversed by a raw gas stream, in which reactors a liquid and/or solid reaction product is deposited.  The reactors are traversed sequentially in the flow direction and operated at different temperatures. Following a shift to a subsequent cycle, the reactor that was traversed first in the previous cycle is traversed last in this subsequent cycle.  Each reactor is operated at a temperature at which the other reactor was operated in the previous cycle.  According to the invention, in the end phase of a cycle, precooling of one reactor and/or preheating of the second reactor is performed before the sequence in which the reactors are traversed is reversed to change the cycle.  Precooling or preheating prior to changing the cycle in the reactors can be accomplished by mixing a cooling/heating medium into the raw gas stream (especially in adiabatically-operated catalyst beds) and/or by means of cooling/heating coils in the reactors (especially in quasi-isothermally operated reactors).  The method according to the invention offers special advantages for desulfuration of raw gas stream containing at least H2S and possibly SO2, COS, and/or CS2, by catalytic conversion of H2S with SO2 and/or O2 into elementary sulfur and water, and possibly by hydrolysis of COS and/or CS2.

Title: Filter device for the filtration of fluids
Inventor: VAN ROSSEN LEONARD M
IPC: B01D29/03
Filed: 1994-02-22
Abstract: The filter device (10), provided for the filtration of fluids, comprises two interconnected material structures (14, 16) forming a filter unit (12). The two material structures (14, 16) are mechanically stable, at least one of the two material structures (14, 16) being elastically deformable. The two material structures (14, 16) an connected to each other at opposite connecting sites, with one (16) of the material structures forming an arch between the connecting sites. This arch has been generated by elastic deformation of the respective material structure (16) so that this material structure (16) is mechanically biased. A stretching movement of this material structure (16) is prevented by the connection of this material structure (16) to the other material structure (14) which in turn is of substantially plane configuration and is tensioned. Each thus constructed filter unit (12) offers high stability against the forces generated by the fluid flow so that a filter element (10) comprising such filter units can be inserted without additional constructions or elements which maintain the arched structure of the curved one material structure (16).

Title: Bicycle wheel travel path for selectively applying chainstay lengthening effect and apparatus for providing same
Inventor: KLASSEN JAMES B
IPC: B62M9/00
Filed: 1996-01-25
Abstract: A rear suspension system for a bicycle.  The system   directs   the   rear   wheel   along   a predetermined, S-shaped path as the suspension is compressed.   The path is configured to provide a chainstay lengthening effect only at those points where this is needed to counterbalance the pedal inputs of the rider; at those points in the wheel travel path where there is a chainstay lengthening effect, the chain tension which results from the pedal inputs exerts a downward force on the rear wheel,  preventing  unwanted  compression  of  the suspension.   The system employs a dual eccentric crank  mechanism  mounted  adjacent  the  bottom bracket  shell  to  provide  the  desired  control characteristics.
