Abstract: A pressure limit valve for well tools where a valve member is moveable between a first closed portion, an open position and a second closed position. A spring for closing the valve is separated from a locking chamber which contains locking elements.      The locking elements are located in a locking chamber and are held deactivated by a release sleeve which separates from the valve member in an open position. When the valve moves to the second closed position it is locked by engagement of the locking elements with a stop shoulder. In use between closely coupled inflatable packers, the valve prevents trapped pressure between the packers from affecting operation of the packer valve.

Abstract: Un pistolet pour produit de calfeutrage, sans égouttage, possède un dispositif d'actionnement (40) sollicité par un ressort, et un plongeur (32) qui presse contre un piston interne (54) d'un tube (12) du pistolet pour distribuer le produit de calfeutrage. Le disque flexible (36) prévu autour de l'extrémité (62) du plongeur forme un joint d'étanchéité avec l'intérieur du tube (12), ceci permettant de créer un vide partiel lorsque le plongeur (32) est rétracté. Ce vide agit sur le piston (54) et provoque une rétraction partielle, et par conséquent l'élimination de la pression sur la matière de calfeutrage à l'intérieur du tube (12) ce qui arrête la distribution du produit de calfeutrage qui cesse de sortir du tube (12).

Granted: 2004-05-18
Abstract: A prediction-type medical thermometer (11) comprises a base housing (13) and an elongated probe (15) connected together by a flexible wire (16). The probe (15) includes an elongated base (21) and a special hollow probe tip (23) having a low heat capacity and which contains a thermistor (19) and a resistive heater (31) that is actuated only upon removal of the probe (15) from the base housing (13). The heater (31) regulates the temperature of the probe (15) to a value of about 93 °F. After the probe (15) is applied to the patient, a microprocessor repeatedly samples the thermistor (19) and estimates the patient's temperature based on the successive samples. For example, if a predetermined number of successive temperature estimates lie within a predetermined error range, the sampling is terminated and the most recent temperature estimate is displayed as the patient's temperature.

Granted: 2000-10-17
Abstract: Four stages of digital cellular architecture are presented which reuse much of the existing voice infrastructure while allowing graceful introduction of data and integrated voice/data services over industry standard, low cost platforms. First, a separate ATM-based infrastructure is introduced that supports data services. A new data call control is introduced on industry standard hardware platforms using object oriented and modular programming. Second, ATM is introduced at radio ports and call control functions are migrated to the new ATM-based call control platforms. Third, vocoders are introduced at the DCS. Fourth, the cellular functions of the legacy cellular switch are phased out and replaced by the ATM-based target architecture.

As the data are sent in trains of more than one ATM cell, the connection control (32) of the  core can be made to operate at a much slower speed. Electro-optical arrangements of the space switch core (Figure 8) are described as embodiment s.

Abstract: The invention relates to a terminal, isolating or connecting strip for telecommunications and data technology, having contact elements and having a mounting apparatus.  The object of the invention is to develop a terminal, isolating and connecting strip of the genetic type, by means of which very different circuit, protection and measurement tasks in telecommunications and data technology are ensured in a very small space, with an increased wiring density, reliably and with a high level of operator convenience and clarify, it being necessary to ensure reliable separation between the competence areas of network operators and subscribers.  This is achieved by introducing insulation-piercing terminal contact elements into two insulating bodies which are arranged at an angle with respect to one another.  The insulation-piercing terminal contact elements are formed continuously over two planes and form two rows of terminal strips which are at an angle with respect to one another.  The lower insulating body has latching elements for latching onto a profiled rail or the mounting bracket in two latching positions.

Granted: 2000-09-19
Abstract: An over-fire air control system for a pulverized fuel furnace, in which a burner assembly is provided for discharging a fuel/primary air mixture along with secondary air to combust the fuel. The amount of primary air and secondary air discharge is controlled to achieve incomplete combustion, and an overfire air port is provided through which additional air is discharged to complete the combustion. The overfire air port receives two streams of air, one high in volume and low in velocity and the other low in volume and high in velocity. Dampers are provided for controlling the air streams to achieve optimum quantities and velocities of the air. According to one embodiment, a source of one of the air streams is the primary air portion of the fuel/primary air mixture applied to the burner assembly. As a result, the formation of nitrous  oxides are reduced and fairly precise air fuel ratios can be maintained despite variations in the quality of the fuel and the pressure and amount of primary air.

Title: Credit status checking system for transaction processing system and checking method therefor
Inventor: UTSUMI KATSUNORI
IPC: G07F7/08
Filed: 1998-06-09
Granted: 2007-07-31
Abstract: A credit status checking system capable of examining credit status of a customer immediately and easily, by utilizing a telephone number recorded regarding the customer through a computer system performing the examining procedure automatically is disclosed. A telephone number examining apparatus connected with ISDN as a subscriber terminal processes circuit-switched call control procedures defined in the ITU-T recommendation Q.931 as a calling terminal. A database manager searches a customer file corresponding to a customer ID input by a customer through an automated transaction machine, retrieves a telephone number contained in the customer file,and transmits the number to the telephone number examining apparatus. The telephone number examining apparatus sends a SETUP message including an unrestricted or a restricted digital information in a bearer capability information element to the network where the telephone number received from the database manager defined as a called party number. When the network does not receive the SETUP message sent and transfers a DISCONNECT message, the examining apparatus performs a clear sequence immediately and obtains a cause in an information element of the DISCONNECT message from the network. When the cause indicates one of the predetermined set of causes, e.g., "Unallocated (Unassigned) number", the examining apparatus determines the number null, and notifies of the credit information manager that the telephone number is null.

Title: Process for silica and magnesium salts production from tailings coming from asbestos mining
Inventor: DELMAS MICHEL P B
IPC: C01B33/12
Filed: 1998-07-27
Granted: 2010-05-11
Abstract: There are numerous technologies to extract magnesium from tailings piles coming from asbestos mining. In the invention we have found that silica which is a component of the asbestos fibers with magnesium oxide can be extracted with magnesium in combining extraction of the asbestos fibers by flotation (wet-milling technologies), the treatment of the water-soaked fibers with an acid and, after reaction the separation of the solid silica from the magnesium salt solution which can then process. The silica shows a great surface area (400 -450 m2/g) which makes it a valuable product with many industrial applications. The extraction of these two products gives a good profitability to this new tailings processing technology.
