Title: Heat exchanger
Inventor: YANAI HIDEYUKI
IPC: F28F9/00
Filed: 1997-10-17
Abstract: A heat exchanger which is constructed such that combustion gas passages (4) for passage of combustion gas and air passages (5) for passages of air are arranged alternately, and the heat exchanger is cut at one end side thereof in an unequal angle configuration to form combustion gas passage inlets (11) and air passage outlets (16), and cut at the other end side thereof in an unequal angle configuration to form combustion gas passage outlets (12) and air passage inlets (15). The combustion gas passage inlets (11) and combustion gas passage outlets (12), through which a combustion gas having a larger volume flow rate passes, are formed on a long side of an angle, and the air passage inlets (15) and air passage outlets (16), through which an air having a smaller volume flow rate passes, are formed on a short side of an angle. Accordingly, it is possible to avoid an increase in pressure loss caused by a volume flow rate difference between a high temperature fluid and a low temperature fluid to reduce pressure loss in the entire heat exchanger.

Title: System and method for changing subscriber service features in a radio telecommunications network
Inventor: FOTI GEORGE
IPC: H04W8/18
Filed: 1997-12-16
Abstract: A method and system for changing subscriber service features in a radio telecommunications network is disclosed. The method begins by a subscriber originating a call from a telephone (34) located in a telecommunications network to a roamer port (37) located within a Mobile Switching Center (MSC) (27) which may be located inside or outside the subscriber's home coverage area. The MSC sends a dial tone (49) to the telephone. Next, the subscriber sends a feature code (51) and Mobile Identification Number (MIN) through the telephone to the MSC requesting a service feature change. The MSC recognizes and verifies the feature code as a valid code. The MSC also associates a service feature change corresponding to the feature code and associates the MIN with a HLR (45). The MSC sends a feature request invoke message (53) to the associated HLR requesting a service feature change. Then, the HLR  implements the service feature change in the HLR. If the roamer port coverage encompasses more than a single MSC, and the subscriber is located in an MSC  (52) that does not include the roamer port, the HLR updates the subscriber's categories in the MSC in which the subscriber is currently registered.

Title: Method and system for connecting a caller to a content provider
Inventor: WALKER JAY S
IPC: G07F17/16
Filed: 1997-12-31
Abstract: The invention relates to methods and systems for connecting a caller (110) to a content provider (120) who provides a service to the caller over the telephone system. In accordance with the invention, a caller (110) establishes a prepaid account (300) with an intermediary, termed a transaction processor (200). When the caller (110) wishes to access a content provider (120), the caller (110) makes a telephone call to the transaction processor (200) providing access to a plurality of content providers (120) via a common access number. The caller (110) identifies his prepaid account (300) and the desired content provider (120). The transaction processor (200) connects the caller (110) to the content provider (120), monitors the connection between the caller (110) and the content provider (120), and debits the caller's prepaid account (300) according to the service provided by the content provider (120).

Title: Internal combustion engine exhaust treating apparatus and method
Inventor: SCAPPATURA EDWARD E
IPC: F01N3/00
Filed: 1999-08-30
Abstract: An apparatus and method for the removal of gases and particulate matter from the exhaust of an automobile. The method includes a heat exchanger connected to the automobile system for cooling and condensing a major portion of the exhaust into a liquid condensate. The condensate enters a first reactor which neutralizes any acids present in the condensate and passes through an automatic drain into a holding tank. The non-condensed gases flow into a second reactor connected to a holding tank. Gases are reacted in the second chemical reactor with a substance which absorbs carbon monoxide, carbon dioxide and nitrogen oxide. The two reactors remove a large quantity of nitrogen oxides and particular matter. The treated gases then are let into the atmosphere through an exhaust outlet.

Title: Systeme d'installation permanente des sondes de mesure a l'interieur d'un conduit par verrou amovible par pression de fluide
Inventor: MEYNIER PATRICK
IPC: E21B47/01
Filed: 1999-12-17
Abstract: - Système d'installation permanente des sondes de mesure contre la paroi intérieure d'un conduit tel qu'un puits ou un tube. - Les sondes de mesure sont associées respectivement à des dispositifs de couplage qui sont amenés jusqu'à leurs emplacements respectifs de couplage dans le conduit au moyen d'un tube positionné par des excentreurs, par exemple. Chaque dispositif de couplage comporte un élément flexible portant la sonde, que l'on déforme vers une position de retrait où on l' immobilise par un verrou, pour permettre son déplacement le long du conduit. Pour libérer les lames flexibles, on établit une surpression suffisante pour faire reculer le piston d'un vérin dont le cylindre communique à une extrémité avec l'intérieur du conduit. Dans cette position dilatée, elle immobilise le dispositif de couplage et plaque la sonde contre le conduit tout en la découplant mécaniquement du tube. Le tube peut éventuellement être retiré, s'il n'a pas d'autre usage. - Applications à la surveillance de longue durée (notamment sismique) d'une zone souterraine en cours d'exploitation, le tube de mise en place des sondes pouvant être un tubing d'exploitation.

Title: Plastic structural element with inserts
Inventor: REIF GEORG
IPC: B29C70/86
Filed: 2000-03-29
Abstract: Inserts of metal 13 in the plastic 11 of the plastic structural element 57 are coated with a coupling layer 12 of fibre-reinforced plastic, which reduces the abrupt change in stiffness and/or coefficient of thermal expansion at the joining interfaces in the metal-plastic composite. By altering the volume fraction of fibres and/or by means of different orientation of the fibre layers within the coupling layer (12), a gradual change in the E-modulus and the thermal expansion coefficient are produced, as a result of which abrupt changes in these values at the composite interfaces can be avoided. The sudden change in stiffness between the plastic material 11 and the metal insert 13 is also reduced by reducing the stiffness of the insert 13, which again is achieved by specific choice of shape. Preferred, in particular, is a finger-shaped fanning out of the insert 13 in the plastic material 11.
