Title: Locking mechanism for use with one-time access code
Inventor: KUCHARCZYK DAVID
IPC: A47G29/20
Filed: 2001-04-23
Abstract: A request for an access code for a locking mechanism is received; and a one-time use access code for the locking mechanism is subsequently issued. The one-time use access code may be issued from a list of currently available access codes for the locking mechanism in response to a request therefor, for example by a merchant or delivery service. Such a code may be issued by a server, which server is further responsible for updating the list of available access codes in response to an indication that a code has been used or has otherwise expired. The list of currently available access codes is preferably a subset of all access codes for the locking mechanism, which codes may be generated using a cryptographically strong random number generator.

Title: System and method for secure transactions over a network
Inventor: MUNSHI ANEES
IPC: H04L12/56
Filed: 2000-09-15
Abstract: The public Internet is the world's largest system of inter-net-worked computers. Adequate security means for protecting sensitive data com-municated over the Internet is not, however, provided. The present invention, therefore, provides a system and method for performing secure transactions over an insecure packet-switched communication network. This is achieved by inter-connecting a number of master nodes over the insecure communication network.  The master nodes are capable of transmitting encrypted data packets over the in-secure network via pseudo-random communication paths. The master nodes are further capable of returning to any state in a secure transaction in the event of a network failure. The master nodes are also capable of using new keys to encrypt each data packet.

Abstract: A graft copolymer comprising a polyamide to which is grafted a glycidyl grou p- containing acrylate copolymer. The graft copolymer can be prepared by dispersing in an organic solvent a polyamide and a material which will react  with the polyamide to form the graft copolymer of the polyamide and the acrylate copolymer and reacting the polyamide and the material so as to form  said graft copolymer. The graft copolymer can exhibit improved toughness and  reduced friability and can be used to form molded articles and in coating compositions, especially powder coating compositions. The coatings can exhib it transparency, reduced brittleness and increased chip resistance. The powder coatings can further exhibit high gloss and smoothness due to superior flow characteristics thereby enabling thinner coatings to be used that provide acceptable appearance.

Abstract: Un gaz d'atomisation, tel que de la vapeur, et un fluide chaud comprenant un liquide chaud à atomiser, passe sous pression dans des conduits de fluide séparés prévus dans un moyen d'échange thermique dans lequel le liquide chaud chauffe la vapeur de manière à la porter à une température de surchauffe, par échange thermique indirect. La vapeur surchauffée est ensuite injectées dans le fluide chaud constitué d'un fluide à deux phases, comprenant de la vapeur et un liquide chaud, consécutivement à l'injection de vapeur surchauffée. Le fluide à deux phases passe ensuite dans un moyen d'atomisation, tel qu'un orifice, puis dans une zone d'atomisation à pression inférieure, ce qui induit la détente de la vapeur et l'atomisation du liquide, si bien que ce dernier se transforme en brouillard de gouttelettes liquides. Le fluide à deux phases est formé avant l'injection de vapeur surchauffée ou consécutivement à celle-ci, et est de préférence continu en vapeur lorsqu'il passe dans le moyen d'atomisation. Le procédé de l'invention est utile pour l'atomisation d'une huile d'alimentation chaude, pour un procédé de craquage catalytique en lit fluidisé.

Title: T-slot milling cutter and insert therefor
Inventor: NORRIS DAVID
IPC: B23C5/28
Filed: 2002-01-22
Abstract: The T-slot milling cutter disclosed employs an indexable insert (29) hav-ing two alternative edge surfaces which serve alternatively as the rake face (31) and rear abutting face of the insert (29) which transfers the cutting force to the rear wall of the in-sert pocket (23) of the cutter. The alternative edge surfaces comprise three facets (45, 51, 45), one (51) central to the surface and the other two (45, 45) receding from the central facet (51) at equal angles thereto. They serve primarily to wedge the insert (29) into mating angular surfaces in the rear wall of the insert pocket (23) to secure the insert (29) against dislodgement when held in the pocket (23) by the customary attaching screw (37) and, by their obliquity to the cutting direction, improve the cutting action when serving as the rake face (31).

Abstract: Cette invention se rapporte à un transistor d'extraction (10), du type transistor à effet de champ (FET), qui comprend un canal conducteur s'étendant via un puits quantique InSb de type p (22) entre des couches InAlSb de type p (20, 24) à largeur de bande interdite étendue. L'une de ces couches InAlSb (24) contient une couche dopante .delta. de type n ultramince (28) en Si, qui fournit une source dominante de porteurs de charge pour le puits quantique. Elle sert de support à des électrodes de drain et de source de n?+¿ (30a, 30b) et à une grille isolée (30c). L'autre couche InAlSb (20) est contiguë à une couche barrière (19) de largeur de bande interdite plus étendue, sur une couche de substrat (14) et sur un substrat (16) avec électrode (18). La polarisation de l'une et/ou l'autre des électrodes de drain et de source (30a, 30b) de façon positive par rapport à l'électrode (18) du substrat, produit une extraction des porteurs minoritaires dans le puits quantique (22) réduisant sa contribution intrinsèque à la conductivité, lui conférant un régime saturé extrinsèque et réduisant le courant de fuite.
