Title: System and method for providing anonymous personalized browsing in a network
Inventor: MATIAS YOSSI
IPC: H04L29/06
Filed: 1997-11-27
Granted: 2004-01-13
Abstract: For use with a network having server sites capable of being browsed by users based on identifiers received into the server sites and personal to the users, alternative proxy systems for providing substitute identifiers to the server sites that allow the users to browse the server sites anonymously via the proxy system.  A central proxy system includes computer-executable  routines that process site-specific substitute identifiers constructed from data specific to the users, that transmits the substitute identifiers to the server sites, that retransmits browsing commands received from the users to the server sites, and that removes portions of the browsing commands that would identify the users to the server sites.  The foregoing functionality is performed consistently by the central proxy system during subsequent visits to a given server site as the same site specific substitute identifiers are reused.  Consistent use of the site specific substitute identifiers enables the server site to recognize a returning user and, possibly, provide personalized service.

Title: Process for mobile subscriber identification card, and card capable of executing the said process
Inventor: MARTSCHITSCH ANDREAS
IPC: H04M17/02
Filed: 1998-01-20
Granted: 2006-03-21
Abstract: A SIM card to identify the mobile telephone subscriber (2) includes an ACM charge notice counter (23) indicating the amount corresponding to the communications carried out with the card.  An EEPROM memory (29) in the card includes an ACMmax file (24) indicating the maximum value of the charge notice counter, and at least one EF FDN file (26) indicating at least one no-charge telephone number.  The means to compare (20, 27) compares the amount indicated by the charge notice counter (23) with the maximum amount of the charge notice counter, and controls the means to block calls (20, 27) according to the result obtained.  The blocking means do not, however, block calls destined for one or more numbers stored on the card.  It is therefore possible to call an emergency number, for instance, or a server number to recharge the card, in the case of a prepaid card, even after the credit on the card has expired.

Title: Fuel injection internal combustion engine with sub-combustion chamber
Inventor: UEDA MINORU
IPC: F02M61/04
Filed: 1998-04-23
Granted: 2007-12-18
Abstract: A fuel injection internal combustion engine is provided with a sub-combustion chamber in communication with a main combustion chamber. A  mixture switching valve is provided for injecting the mixture of the fuel and compressed air, and a spark plug is arranged in the sub-combustion chamber.  The sub-combustion chamber is formed of a material having a thermal conductivity which is lower than that of the material forming the main combustion chamber.  The combustion efficiency is enhanced even when the fuel is injected to the sub-combustion chamber from the mixture switching valve with low pressure compressed air. An injecting device directly and intermittently injects mixture gas into the sub-combustion chamber. The injecting device is a mixture gas injection device including a pressure accumulating chamber adjacent to the sub-combustion chamber and to which pressure air is filled, an opening or closing valve to cause the pressure accumulating chamber to be communicated with the sub-combustion chamber in such a way that they may be opened or closed, and a fuel injecting valve for injecting fuel into the pressure accumulating chamber. Mixture gas with an air-fuel ratio adapted for an operating state of the engine over a wide operating range is supplied to the combustion chamber. A volumetric ratio of each of the sub-combustion chamber and the main combustion chamber is set within a range of 2:8 to 6:4. A discharging amount of hydrogen carbide is less and a high efficiency can be attained.

Abstract: A wheel arm assembly for an implement includes a common wheel arm for single wheel, straight tandem wheel, or walking beam configurations. In the straight tandem configuration, a pair of spindles are supported in corresponding bushings at the end of the wheel arm. The spindles are axially aligned, project outwardly from the arm, and support a pair of wheels in tandem. To convert to the optional walking beam configuration, the operator removes the spindles from the bushings and inserts a long pin through a selectively attachable walking beam casting and through the bushings in the arm. The same spindles that attach the wheels to the arm in the conventional tandem configuration are inserted in the offset ends of the walking beam to support the wheels from the walking beam casting.

Title: Method and apparatus for expanding and conferring a cup shape to the terminal junction segment of bi-axially oriented pipes made of thermoplastic material
Inventor: TABANELLI GIORGIO
IPC: B29C33/02
Filed: 1999-01-13
Granted: 2007-01-09
Abstract: The invention provides for conferring a cup shape to the terminal junction segment (2) of pipes that are bi-axially oriented longitudinally and circumferentially and hence very sensitive to diameter and length reduction through heat, by means of passage into a furnace (4) which heats the segment (2) to a differentiated temperature, increasing towards the end of the segment (2), whose inner diameter progressively drops down to a controlled value, as temperature increases (whilst length is simultaneously reduced, with a corresponding increase in thickness). Preferably then, in an appropriate station (33), an additional heating is executed to a plastic deformation temperature suited to obtain a correct preliminary dilation of the terminal segment (2), introducing a rigid element (34) which acts as inner contrast, thereby inhibiting any retraction thereof. Here the segment (2) undergoes a thickening of the dilated wall both during the introduction of the rigid element (34), and during its extraction therefrom. Such terminal segment (2), dilated and heated, is then easily and rapidly fitted onto a calibration expander (3), itself also heated to such a temperature as to limit heat absorption from said segment (2). Here too the terminal end (2) thickens yet again and takes its shape and, after the possible additional heating to force the terminal segment (2) to adhere spontaneously and perfectly to the underlying expander (3), at least the outer surface of the terminal segment (2), thus shaped, is cooled.

Dans un mode d'essai d'impédance de dérivation, le dispositif de terminaison d'une dérivation de défibrillation mesurée est relié à la masse du système, et une tension d'excitation est appliquée dans un chemin d'excitation à partir d'un dispositif de terminaison de dérivation de force sélectionné parmi les dérivations de stimulation. Une dérivation de mesure est sélectionnée parmi les autres dérivations de stimulation et dérivations de défibrillation, et la tension produite dans la dérivation soumise à un essai est mesurée au moyen de la dérivation de mesure, de l'interface électrode/tissu de la dérivation de mesure et de la dérivation de défibrillation soumise à un essai. Le courant appliqué dans le chemin d'excitation est également mesuré et une valeur d'impédance est dérivée des valeurs mesurées de courant et de tension. On continue l'essai avec d'autres sélections de chemins d'excitation et de mesure. On utilise également des comparaisons des impédances mesurées avec des valeurs maximales et minimales d'impédance pour déterminer des défaillances d'intégrité de dérivation. L'impédance de dérivation entre deux dérivations de défibrillation est déterminée comme une fonction de la somme des impédances de dérivation de défibrillation dérivées.
