Title: Internal combustion engines with fluid fuel reforming ceramic catalyst and transporting and power-generating means employing them
Inventor: ICHIMURA SHOJI
IPC: B01J23/89
Filed: 1997-03-04
Abstract: Internal combustion engines decrease environmental pol-lution and increase energy efficiency by using a fluid fuel reforming ceramic catalyst comprising a core 2 of a complex oxide ceramic of transition metals, an intermediate layer 3 of an alumina-based silicate ceramic covering the core 2 and an outer layer 4 of a ceramic containing noble metals.          Transporting and power-generating means using such internal combustion engines increase the combustion efficiency and decrease the noxious substances in exhaust gases by convert-ing the incombustible and environment polluting substances contained in fluid fuels to combustible substances and acti-vating the oxygen in the air contained in fluid fuels.

Title: Microwave antenna feed structure
Inventor: COX GARY A
IPC: H01Q3/18
Filed: 1997-05-30
Abstract: A feed structure for transmitting or receiving microwave energy to or from a reflector includes a waveguide having an input section, intermediate section, and output section. The waveguide has an inner surface of generally rectangular cross section and an outer surface of generally circular cross section. The outer surface includes unique opposing convex surfaces which enables the waveguide to be bent with minimal resulting deformation of the internal rectangular surface. At least one locating surface is provided on the outer surface of the waveguide for determining the orientation of the waveguide. The input section of the waveguide has a threaded cylindrical surface adapted to be connected to a hub having a threaded interior bore which is connected to the reflector. A feed horn integral with the output section of the waveguide and having a circular output aperture is formed by machining the inner surface of the waveguide into a rectangular to circular transition. The intermediate section of the waveguide is curved so that the output aperture of the horn is directed toward the reflecting surface of the reflector, enabling waves transmitted from the aperture toward the reflecting surface to be reflected into space in the form of plane waves.

Inventor: MCKENNA MARTIN KALANI
IPC: G16H30/20
Filed: 1997-07-24
Abstract: A programmable, medical imaging system (250) which incorporates algorithms for enhancing the usability of the system for clinicians is described. With respect to programmability, and in one aspect, the present invention relates to a programmable system which includes a learn mode usable for script generation. In the learn mode, a user can rehearse a sequence of actions and save those actions to be replayed later. In another aspect, the present invention is directed to an algorithm (300) which provides a non-blocking, synchronous interface to an underlying asynchronous architecture. Generally, the algorithm decouples the client-server portion of the application from the synchronous development environment. Using this algorithm (300), a programmer can develop a non-blocking, highly interactive, client-server application without having to resort to asynchronous programming techniques. In yet another aspect, the present invention is directed to an overlap detection and correction algorithm (400) which, in one form is integrated into a review template editor for creating review templates. The overlap detection and correction algorithm (400), in one embodiment, is a one or two boundary rectangular cell overlap detection and correction algorithm (400).
Patent CA-2213926-A1 (CA)
Inventor: AHGHAR MASSOUD
IPC: C01F7/762
Filed: 1997-08-26
Abstract: A process in which a leach liquor of Al2(SO4)3 + K2SO4 + Fe2SO4 and other sulphates is introduced to a surface-cooled crystallizer that drops the Al2(SO4)3 + 18H2O.  The leach liquor is pumped through a heat exchanger that keeps a temperature of 160°F and the surface temperature of the surface-cooled crystallizer is maintained at 60°F. The temperature gradient within the leach liquor promotes crystal formation.  These crystals are then supplied to mixture which includes K2SO4 in a simple crystallization and evaporation step that uses a vacuum of twenty inches of mercury and heat to drop Al2(SO4)3 + K2SO4 + 24H2O.  A pressure of 250 PSI and a temperature of 200°C are then applied in a discrete continuous process that yield a basic sodium or potassium aluminum sulphate and excess sodium sulphate or potassium.  The excess sodium sulphate or potassium sulphate is returned to the simple crystallization and evaporation step.  The basic sodium aluminum sulphate comprises particles that are at least forty percent below two micron. This is then applied to a delaminator that converts eighty-five percent of the particles to under two micron.  The BKAS and/or BNaAS is used as a filler in the making of paper.

The identification of the actual recipient is encrypted (308) and sent (312) along with the message to the service provider. Upon receipt, the service provider decrypts (408) the actual recipient information to determine the identification of the actual recipient. The service provider reformats (412) the delivery information to indicate that the actual recipient is the recipient of the message and that the service provider is the sender of the message. The identification of the actual sender is encrypted (416) and sent (420) along with the message to the actual recipient. The recipient receives the message from the service provider. The recipient may decrypt the encrypted identification of the actual sender to learn who sent the message. The message contents may optionally be encrypted as well to ensure message privacy as well as user privacy.

Abstract: A communication terminal (MT) is equipped with a first communication unit (KOM1) for communicating with radio network base stations (DECTS) via a first radio interface (RI1), and with a second communication unit (KOM2) for communicating with a mobile radio network (MN) via a second radio interface (RI2).  The terminal (MT) determines whether it has moved into the range covered by the radio network base stations.  If it has moved into the range (RADECT) covered by a selected radio network base station (DECTS), it initiates a switch-over of the network-side routing of connection requests which are directed to the terminal (MT), and routes them via the selected radio network base station (DECTS).  The initiation of the switch-over takes place by signalling the mobile radio network (MN).
