Title: System and method for eliminating unsolicited e-mail
Inventor: IVEY CHRISTOPHER LIAM
IPC: H04L9/32
Filed: 2003-11-13
Granted: 2009-08-04
Abstract: The invention is a system and method for eliminating unsolicited e-mail. The invention employs the simple approach of limiting correspondence to known correspondents through a system of authentication, while allowing persons who are not authenticated correspondents to petition correspondence by means of an extremely restrictive message format that is useless for marketing purposes. The system uses a Header Parser [102] to sort all incoming electronic mail into solicited and unsolicited messages without parsing the message body. It allows unauthenticated correspondents to solicit correspondence by means of a specially tagged message format called a Request Correspondence Message, and makes use of a Format Inspector [103] to ensure that all such solicitations meet strict format requirements which make it impraticable to use such messages for the purposes of marketing or solicitation. Authenticated Correspondents are managed for each user with an Authentication Key Database [106]. The integrity of the system is maintained by means of a transactional exchange of authentication keys, which are transformed with each exchange to prevent keys from being intercepted and reused. This method allows users to maintain absolutely unique key signatures, which can be attached to message headers and sent in, clear without fear of interception or spoofing. This safeguard makes it impossible to share, sell, or compromise users' correspondent lists, and makes this approach to eliminating unsolicited e-mail unique from any similar method that employs correspondent lists.

Abstract: L'invention concerne un procédé thérapeutique consistant à construire un vecteur d'expression/réplication de cellule spécifique destiné à traiter, en particulier, une tumeur maligne, pouvant exprimer et répliquer un gène dans des cellules spécifiques, notamment dans celles d'une tumeur maligne, sans porter préjudice aux cellules normales (un vecteur capable, en particulier, de réguler l'expression/réplication à un point recherché après l'expression/réplication) et à transférer ce vecteur dans des cellules spécifiques telles que celles d'une tumeur maligne in vivo, suivie de l'expression du vecteur. Le domaine régulant l'initiation de transcription d'un gène calponine humain, exprimé spécifiquement dans une cellule, est acquis et lié en amont d'un gène associé à la réplication virale tel que ICP4. Puis, un ADN codant une protéine, telle qu'un régulateur de l'angiogénèse ou un facteur associé à l'apoptose, est lié au gène associé à la réplication virale, comme décrit ci-dessus, via IRES, alors qu'un gène thymidine kinase, dans un état intact, est intégré dans un ADN viral. On obtient ainsi une construction de vecteur d'expression/régulation de cellule spécifique qui n'agit pas sur des cellules adultes normales. Ce vecteur construit est transfecté dans des cellules de tumeur maligne de façon à faire éclater les cellules de tumeur maligne.

Title: Footwear sole component with a single sealed chamber
Inventor: SWIGART JOHN F
IPC: A43B13/20
Filed: 2003-05-08
Granted: 2009-02-17
Abstract: A sole component for footwear combining the desirable response characteristics of a fluid filled chamber and an elastomeric material. The chamber (14, 14') can be formed as a single bladder chamber (14, 16) in contact with an elastomeric midsole (12), or a single chamber formed by a sealing (19) a void in elastomeric material. The interface between the chamber and elastomeric material is sloped and gradual so that the shape of the chamber and its placement in a midsole determine the combination of response characteristics in the sole component. The chamber (14, 14') has a relatively simple shape with one axis of symmetry with a rounded portion (27) and a narrow portion (29). Varying the placement of the chamber in the elastomeric material can simulate the impact response of more complex and expensive systems with only a single chamber shape that needs to be stocked. The chamber has a relatively large volume, is devoid of internal connections, and has an internal pressure within 5 psi if ambient pressure, and preferably at ambient pressure. Since air is used as the fluid, no specialized gases are required. No specialized films or bladder materials are required where the chamber is formed as a bladder, since the bladder is not highly pressurized. Manufacture is simplified and design flexibility enhanced with only one type of air chamber.

Granted: 2008-09-16
Abstract: In a fuel cell, a porous portion (32) is formed in a separator. At a surface of the porous portion opposite to a surface where a reactant gas passage is formed, a cooling gas passage (33) is formed. The cooling gas passage (33) may be fluidly connected to a reacta nt gas supply passage for supplying reactant gas to the fuel cell. The cooling gas passage (33) is controllable in flow amount. The porous portion (32) is formed only in a separator portio n where a downstream portion of the reactant gas passage (27, 28) is located. At a separator portion where an upstream portion of the reactant gas passage (27, 28) is located, a coolant passage (26) is formed. A rib and a rib-bottom portion have a great porosity. A groove ma y be filled with porous material (49). The porous portion may be replaced by a water exchange portion (32'). A portion of the separator other than the region of the porous portion may b e made by porous material (51). Due to these, a fuel cell can be obtained where removal of product water is improved, product water can be utilized for humidifying gas, and product wat er can be uniformly removed.

Abstract: Disclosed is a preferred mold design for producing plastic, injection molded preforms, which may be blow-molded into a container of a final, desired shape. A preferred mold (500) includes a combination of hardened material components (530a) and high heat transfer material components (530b) to provide a mold (500) having good wear characteristics, for a sufficiently long useful life, and to enable rapid cooling of the injected preform, in order to reduce the cycle time of an injection and cooling cycle. In some arrangements, the hardened materials may form a portion of the preform cavity thereby slowing the rate of cooling in those areas and inducing a semi-crystalline or crystalline structure in the cooled preform.

Abstract: The present invention stably provides a high-strength hot-dip galvanized steel sheet having a high tensile strength and no non-plated portions and being excellent in workability and surface properties even when the employed equipment has only a reduction annealing furnace and a steel sheet containing relatively large amounts of Si, Mn and Al that are regarded as likely to cause non-plated portions is used as the substrate. The present invention: secures good plating performance even when the steel sheet contains Si, Mn and Al by adding Ni to a steel sheet, thus forming oxides at some portions in the steel sheet surface layer, and resultantly suppressing the surface incrassation of Si, Mn and Al at the portions where oxides are not formed; enhances the effect of Ni and accelerates the formation of oxides by further adding Mo, Cu and Sn;  and moreover, in the case of a TRIP steel sheet, secures austenite by determining the ranges of Si and Al strictly, avoiding the deterioration of plating performance caused by the addition of Ni, and further adding Mo in a balanced manner. In addition, the present invention, in a TRIP steel sheet, improves press formability by regulating a retained austenite ratio and accelerates the formation of oxides by regulating a hydrogen concentration and a dew point in annealing before plating.

Abstract: A catalytic hydrocracking process for the production of ultra low sulfur diesel wherein a hydrocarbonaceous feedstock is hydrocracked at elevated temperature and pressure to obtain conversion to diesel boiling range hydrocarbons. The resulting hydrocracking zone effluent is hydrogen stripped in a stripping zone maintained at essentially the same pressure as the hydrocracking zone to produce a first gaseous hydrocarbonaceous stream and a first liquid hydrocarbonaceous stream. The first gaseous hydrocarbonaceous stream containing diesel boiling range hydrocarbons is introduced into a desulfurization zone and subsequently partially condensed to produce a hydrogen-rich gaseous stream and a second liquid hydrocarbonaceous stream containing diesel boiling range hydrocarbons. The first liquid stream is separated to produce a third liquid hydrocarbonaceous stream containing diesel boiling range hydrocarbons which is also introduced into the desulfurization zone. An ultra low sulfur diesel product stream is recovered.
