  • Patent number: 6428708
    Abstract: A filtering apparatus including a fluid monitoring head and a replaceable filter cartridge removably fastened to the head. The fluid monitoring head includes a shut off mechanism for interrupting fluid flow through the cartridge when a predetermined quantity of fluid has been treated by the filter. The filter cartridge is releasably coupled to the shutoff mechanism when the filter is installed. The shut off mechanism includes a valve element carried by a shaft that forms part of a driven member forming part of the monitoring head. A biasing element exerts a force on the valve element carrying shaft tending to move the valve to a flow blocking position. The shaft engages a keeper or hold off element threadly retained in the filter cartridge. As the driven member rotates, the keeper element is gradually unthreaded until it separates from the filter cartridge, allowing the force of the biasing element to move the valve member into a flow interrupting position.

  • Patent number: 6390916
    Abstract: A seal card game system providing multiple levels of non-progressive play. The game system awards a master case award to a winning ticket not among the population of individual deal winning tickets. A winning ticket of each deal set does not qualify for the master case award level. The game features segregated deal sets, each set containing break-open tickets. Each deal set is segregated by deal identifier indicia. In one exemplary embodiment, the deal identifier indicia is a selected color which is imprinted on each of the playing tickets comprising a deal set. The play tickets may be serialized by deal or by case for security. A seal card may includes the serialization of each ticket associated with the case. The non-progression scheme benefits the game operator in retaining the interest and participation of a higher population of players throughout the multiple deal play.

  • Patent number: 6388668
    Abstract: The invention provides a device for converting data types corresponding to functional animations into a form that is amenable to fast renderings of the animation by using of a presentation library. It therefore bridges a gap between the high level flexibility needed to formulate animations with the low level rigid structuring imposed by presentation software that directly interfaces with image rendering and sound presenting hardware. A spite engine interprets a list of sprites which is created and updated by a normalizer software component. The sprite engine must interpret its list at a refresh rate suitable for rendering video images. The normalizer must deal with the functional data types built by the functional animation software and convert those data types into lists of sprites.

  • Patent number: 6378241
    Abstract: The invention relates to a fishing rod accessory having simple design which is connected to a traditional float (1). As a result, a cast bait can be lifted or lowered, as if by remote control, by corresponding movements of the fishing rod. The inventive accessory consists of a hollow body (4) which can be rapidly flooded via the two end openings (for the fishing line (3) to be passed through), and a (submersible) ball (6) lodged inside the hollow body (4). Said ball (6) frees the passage of the line (3), when the hollow body (4) is in horizontal position, by rolling into a trough-shaped hollow, whereas it blocks this passage after swinging around an axis (5a) (i.e. in vertical position) by jamming, together with the line, in the circular and funnel-shaped outlet opening, when the position in question is stabilized (until the next fishing rod) manoeuvre).

  • Patent number: 6374251
    Abstract: A data mining system for use in finding clusters of data items in a database or any other data storage medium. The clusters are used in categorizing the data in the database into K different clusters within each of M models. An initial set of estimates (or guesses) of the parameters of each model to be explored (e.g. centriods in K-means), of each cluster are provided from some source. Then a portion of the data in the database is read from a storage medium and brought into a rapid access memory buffer whose size is determined by the user or operating system depending on available memory resources. Data contained in the data buffer is used to update the original guesses at the parameters of the model in each of the K clusters over all M models. Some of the data belonging to a cluster is summarized or compressed and stored as a reduced form of the data representing sufficient statistics of the data. More data is accessed from the database and the models are updated.
