Title: Controlled release potassium dosage form
Inventor: CHEN CHIH-MING
IPC: A61K9/50
Filed: 1994-09-23
Abstract: A pharmaceutical composition for oral administration of potassium salt in a form not irritating to the gastrointestinal mucosa comprises tablets or capsules of micropellets of a potassium salt, such as potassium chloride. The micropellets are coated with a permeable polymer comprising a low viscosity (10cp,) ethylcellulose in combination with triacetin. This coating provides a strong film resistant to breakage during formation of tablets and filling of capsules. The protective coating of the micropellets prevents the early release of potassium ions, while the tablet or capsule disintegrates and the micropellets are dispersed within the lumen of the gastrointestinal tract. As water passes through the permeable but insoluble coating, potassium ions are gradually eluted into the fluid of the tract over a period of many hours, thereby allowing time for the ions to be absorbed from the tract before high, irritating ion concentrations can form.

Title: Connector for Circuit Boards
Inventor: ARAMIZU TATSUO
IPC: H01R13/71
Filed: 1996-04-26
Abstract: The invention provides a multi-terminal connector for connecting a circuit board to another circuit board. The connector body consists of a first body having a bar-like base part and an uprightly and linearly projecting part and a second body having a slot into which the projecting part of the first body fits.  The first body is to be attached to a circuit board and the second body to another.  The first body has cavities at intervals in the lengthwise direction, and each cavity provides openings in side faces of the projecting part. A shaft extends through the projecting part of the first body, and contact blades are fixed to the shaft in the respective cavities in the first body.  The slot of the second body is laterally enlarged in sections corresponding to the cavities in the first body to provide cross-sectionally circular spaces in the assembled two bodies to allow rotation of the contact blades by turning the shaft.  The second body is coupled with the first body while the contact blades are kept in the vertically extending position.  Connecting terminals are provided in both the first and second bodies, and each contact blade makes contact with at least one terminal in the first body and at least one terminal in the second body when the blade is turned to the horizontally extending position.  Using this connector, a circuit board which is held upright can be attached to another circuit board placed horizontally by laterally moving the upright circuit board.

IPC: B60T8/18
Filed: 1996-04-30
Abstract: A railway freight brake system for operating vehicles in a train wherein each vehicle responds in braking situations as if its effective net braking ratio was a desired train net braking ratio. Embodiments include vehicles receiving a brake signal and utilizing either a received train net braking ratio or utilizing a stored on-board train net braking ratio to control pneumatic equipment on-board the vehicle to produce brake forces on the vehicle generally corresponding to the net braking ratio of the train. Some embodiments use a common train line control to communicate both train net braking ratio and brake signals to the individual vehicle. Individual vehicles can receive periodic or initial train net brake ratio values.

Title: Facet classification neural network
Inventor: BRADY MARK J
IPC: G06N3/00
Filed: 1994-11-23
Abstract: A classification neural network (160) for piecewise linearly separating an input space to classify input patterns is described. The multilayered neural network (160) comprises an input node (162), a plurality of difference nodes (164) in a first layer, a minimum node (170), a plurality of perceptron nodes (166) in a second layer and an output node (168). In operation, the input node (162) broadcasts the input pattern to all of the difference nodes (164). The difference nodes (164), along with the minimum node (170), identify in which vomoi cell of the piecewise linear separation the input pattern lies. The difference node defining the vomoi cell localizes input pattern to a local coordinate space and sends it to a corresponding perceptron, which produces a class designator for the input pattern.

Abstract: An adhesive binding strip (10) for binding pages in the form of a book. The adhesive binding strip includes an elongated substrate (12) made of a formable material. A band (14) of heat-activated adhesive runs down the central portion of the substrate A matrix of heat-activated adhesive is placed on the substrate around all edges of the adhesive band. The adhesive band, which has a low viscosity under activation conditions, binds the pages of the book to each other and to the substrate The adhesive matrix which has a viscosity under activation conditions, serves to bind the entire substrate to the book, while preventing the adhesive band from running out from under the substrate during the binding process. The adhesive matrix also increases overall strength of the binding, especially with respect to the front and back cover pages of the book.

Title: Diversity path co-channel interference reduction
Inventor: ABU-DAYYA ADNAN
IPC: H04L1/06
Filed: 1996-07-10
Abstract: Diversity path signals, each comprising time division multiplexed symbols in a time slot including known symbols, are combined with respective weights to reduce co-channel interference. Initial weights are determined, using a window on the known symbols, to optimize signal to interference plus noise ratio. These weights are used to determine symbols adjacent the window, and the window is changed to include determined symbols and the weights redetermined. This process is repeated with the window being moved progressively, preferably with successive positions overlapping, throughout the time slot. The initially known symbols can comprise synchronization symbols and/or CDVCC (coded digital verification colour code) symbols. Desirably, both can be used with respective windows being moved in opposite directions through symbols between them to provide two results for each such symbol, the better one of which is selected in dependence upon a monitoring of possibly averaged errors for the symbols.

Title: Electro-optic ice detection
Inventor: GREGORIS DENNIS JOHN
IPC: G01N21/35
Filed: 1995-10-31
Abstract: To determine whether ice is present on an aircraft wing, the intensity of light in a band between 1.16 and 1.20 microns is determined as is the intensity in a band between 1.24 and 1.28 microns. The contrast, defined as the difference between the intensities over the sum of these intensities, is determined. Because of the peculiar characteristics of the reflectivity of ice, water, Type I de-icing fluid, and Type II anti-icing fluid, if the contrast is positive, it is an indication of ice on the wing whereas if it is negative it is an indication there is no ice present.

IPC: F22B37/00
Filed: 1995-10-02
Abstract: Procédé et appareil de positionnement à distance d'une sonde, telle qu'une sonde d'examen ou de réparation, dans un élément tubulaire. L'élément tubulaire peut être un tube de transfert thermique d'un générateur de vapeur nucléaire destiné à être examiné ou réparé par la sonde. La sonde est raccordée à un tuyau qui porte celle-ci au fur et à mesure qu'elle avance le long du diamètre interne du tube et se dirige vers le point du tube à examiner ou à réparer. Une partie du tuyau est enroulée autour d'une bobine réceptrice. Lorsque la sonde et le tuyau avancent dans le tube, le tuyau se déroule de la bobine réceptrice. Toutefois, lorsque le tuyau se déroule de la bobine réceptrice, il peut avoir tendance à se "nouer", s'entortiller ou se déformer à un endroit, induisant une contrainte de torsion dans le tuyau. Cette contrainte de torsion peut être suffisamment sérieuse au point de provoquer la rupture du tuyau. L'appareil de l'invention comprend un dispositif de préhension pouvant saisir le tuyau, ainsi qu'un élément de rotation raccordé au dispositif de préhension et faisant tourner à la fois le dispositif de préhension et le tuyau saisi. Lorsque l'élément de rotation fait tourner le dispositif de préhension, ce dernier et une partie du tuyau tournent simultanément afin de détordre la partie tordue et relâcher de cette façon la contrainte de torsion induite dans le tuyau.
