Patent CA-2098987-C (CA)
Inventor: HARPER JOHN
IPC: H04L45/18
Filed: 1992-01-08
Granted: 1999-07-13
Abstract: A technique for logically connecting local area networks (LANs) that may be separated by wide area networks containing routers and other network components. A logical link is formed between two bridge-like devices called tunnelers, such that, once a tunnel has been established between two LANs, other devices on the LANs can communicate as if the tunnel were a bridge. The tunneling mechanism of the invention requires that each LAN or extended LAN have only one active tunneler at any particular time, referred to      as the designated tunneler, and each of the tunnelers is configured to have knowledge of the identities of the other tunnelers. A tunnel is established after a successful exchange of messages between two tunnelers, and then traffic may be forwarded through the tunnel in a transparent manner. The tunneling mechanism permits messages to be forwarded between LANs separated by a wide area network containing routers. Moreover, the mechanism permits filtering of traffic, such that only selected types of traffic, or messages for selected destinations or from selected sources, are forwarded through tunnels. The tunneling mechanism inherently precludes the formation of closed communication loops. An alternate embodiment of the invention optimizes the configuration process for particular network topologies.

Title: Secure credit/debit card authorization
Inventor: COLBERT RAYMOND OTTO
IPC: G06Q20/34
Filed: 1993-07-08
Granted: 1999-06-22
Abstract: This invention relates to methods for making a credit/debit card purchase without revealing the card number to the vendor of services or goods. The card holder is connected to a data base and provides the card number, plus holder identity verification, to the data base. The data base then verifies whether the card holder is authorized to incur the expense of the purchase, and, if so, provides an authorization indication or code to the vendor, the card number cannot be derived from the authorization information, thus helping to preserve the secrecy of the card number.

Abstract: In  an  optical  amplification  system of  the present   invention,  an   ASE   (amplified  spontaneous emission)  light  included  in a  signal  light  band is removed  to  provide  low  noise  characteristics.   The signal  light is  amplified by  an optical amplification unit, and is supplied to an ASE  removal unit.  In  the ASE  unit, the signal light is transmitted therethrough, and  the  ASE  light  is  reflected  in  the  orthogonal direction   to the   light    propagation   direction. Consequently,  the  optical amplification  system having low noise characteristics is obtained.

Abstract: A photographic printer for printing negative images on a negative film onto photographic paper.  The printing direction can be changed over between "lateral" and "longitudinal" without changing the feed direction of the negative film.  A reflecting mirror is inclined by 45° with respect to the optical axis of the light emitted from a light source to the negative film and is supported to be rotatable about the optical axis.  A driving unit is provided to rotate the reflecting mirror by 90° about the optical axis between a reference position and a second position.  Exposure stages are provided on the optical axes of the light beams reflected by the reflecting mirror when the mirror is in its reference position and second position, respectively.  The photographic paper is guided through the exposure stages.  According to the position of the mirror, negative images are printed on the paper at one of the two exposure stages.  Thus, the printing position can be changed over between lateral and longitudinal by turning the mirror between its reference position and second position.

Abstract: Procédés de lavage de zéolites, de préférence d'une taille inférieure à environ 0,5 micron, avec un système de microfiltrage utilisant un liquide détergent, tel qu'une solution aqueuse d'eau (de préférence de l'eau désionisée), pour produire des cristaux de zéolites présentant un pH compris entre 9,4 et 10,0. Le pH est déterminé par une procédure spéciale. Les procédés de lavage préférés consistent à former une boue de cristaux de zéolites avec de l'eau (ou une solution détergente appropriée), à concentrer initialement la boue avec un microfiltre jusqu'à une concentration initiale prédéfinie, à laver les cristaux par adjonction d'eau d'appoint avec le même débit que la perte de fluide due à l'écoulement de perméat jusqu'à ce que le pH du perméat se trouve au-dessous d'une valeur prédéfinie, et à arrêter ensuite l'écoulement d'appoint et à concentrer la boue jusqu'à une concentration finale maximale prédéfinie. On sèche un échantillon de zéolites et on mesure son pH; si ce dernier se trouve dans la plage désirée, le lot de boue à concentration maximale est séché. On utilise ces procédés pour produire des cristaux de zéolites possédant un pH compris entre environ 9,3 et 10,0.

Abstract: A reed 28 for a loom is disclosed which includes a frame with upper and lower baulk mechanisms D, E that carry a front row B of dents 30 on the beat-up side of the frame and a back row C of dents 34 staggered in alignment with dents 30.  Lower baulk mechanism E includes a stepped clamping portion which is reduced in depth compared to the depth of the upper portion of the lower baulk mechanism E such that dents 34 are shorter in height in the lower baulk mechanism E than dents 30.  This renders one of the rows C of dents 34 able to be disposed farther from the other row B of dents 30 than if they were to extend into the clamping portion of the lower baulk mechanism E the same amount as dents 30.  In this way, the angle of attack between the dents and the warp yarn ends is reduced and offers less resistance to the yarn passage, reducing abrasion of the warp yarns, reducing the lint buildup between the dents, and increasing efficiency by reducing the incidence of friction between adjacent warp yarns.

Abstract: A stabilizing system for use with a vehicle suspension which employs a first and second strap or other flexible tension member associated with and extending between opposite control arm assemblies of the suspension.  A first end of each strap is anchored to a corresponding control arm assembly.  A second end, distal the first end, of each strap is anchored to the control arm assembly distal the first end.  Each strap, alternately, weaves over and under at least two guides associated with and positioned between the path of the straps.  The guides and/or bushings associated with the anchor points may be formed of a yieldable material to provide a yieldable biasing action on the straps.  An adjustment assembly is associated with each strap to preload the associated strap to a desired tension.  The stabilizing system occupies space between the control arm assemblies and is very lightweight due to the thin belt-like characteristics of the straps.  The stabilizing system of the present invention functions to transfer forces imposed on one control assembly to the opposite control arm assembly by alternately placing an associated strap in tension or allowing the other strap to go slack.  The flexible tension members or straps are preferrably connected to the control arms at locations tending to minimize the effect of single wheel impact loads.

Abstract: Methods and apparatus for the disposal of solid particulate material in subterranean formations are disclosed. The invention is not limited to the disposal of oil field waste and therefore provides means and methods for the disposal of virtually any type of waste slurry stream. A slurry is formed at the surface of the earth by mixing the solid waste in particulate form with liquid and viscosifier thereby forming a slurry. A borehole is drilled into a selected injection formation and the slurry is pumped from the surface through the borehole and into the injection formation. Some surface pretreating of the slurry may be required including sizing of the particulate solids, adding weighting material, removing excessive amounts of oil and grease and diluting to reduce the level of radioactivity. The injection formation is preferably dipping in angle with respect to the horizontal and highly fractured. The borehole is hydraulically isolated from intervening earth strata between the surface of the earth and the injection formation.
