Patent CA-2470878-A1 (CA)
Inventor: WEAVER MARK
IPC: F16L19/02
Filed: 2004-06-14
Abstract: Un ensemble de robinet avec une colonne montante verticale qui est plus facile à installer pour une installation initiale et une installation après coup. L'ensemble de robinet est doté d'un corps de robinet principal qui définit une cavité se prolongeant de manière axiale. Un mécanisme de verrouillage positif sous forme d'une rondelle frein en étoile compressible de manière flexible est disposée pour reposer sur la partie inférieure de la cavité, qui est équipée d'une ouverture qui communique avec un service d'eau sous pression. Un manchon adaptateur creux est inséré dans la cavité sur la partie supérieure de la rondelle frein en étoile. Un joint torique entre l'extérieur du manchon adaptateur et la paroi latérale environnante qui définit la cavité entraîne un ajustement étanche entre le manchon adaptateur et la paroi latérale. L'extrémité filetée et effilée de la colonne montante est raccordée de manière amovible au manchon adaptateur en étant vissée dans l'ouverture filetée et effilée du manchon adaptateur. Un écrou de retenue qui est monté de manière coulissante par-dessus la colonne montante est vissé sur le corps du robinet principal pour confiner le manchon adaptateur dans la cavité et empêcher un déplacement axial du manchon adaptateur à l'extérieur de la cavité. Le resserrement de l'écrou de retenue au corps du robinet principal exerce une pression sur le manchon adaptateur qui comprime la rondelle frein en étoile, qui empêche la rotation du corps du robinet principal par rapport au manchon adaptateur et à la colonne montante.

Title: System and method for presentation of wireless application data using repetitive ui layouts
Inventor: FRITSCH BRINDUSA L
IPC: G06F9/44
Filed: 2005-02-25
Abstract: A Repetitive Layout scheme is provided that operates on a collection of data objects, such that each data object accords to the same data object definition (data model) expressed in a structured definition language. The Repetitive Layout consists of one UI  section repeated for every object in the collection. Each UI section is composed of a set of UI  controls or sub-layouts. The UI controls in each section are associated with the data fields of the corresponding data object. A user of a wireless application interacting with the data objects can select UI sections and edit the controls within them via the user interface of the wireless device executing the application. Any modifications are propagated to the data objects mapped to the respective UI sections. Similarly, all modifications (driven by the application logic or incoming server messages) to the data objects are reflected in the UI section mapped to these objects. The generation and application of the repetitive layout scheme can include the steps: dynamic data entity generation (Data Composer stage); determining the collection of data objects that need to be presented by the user interface (Rules Engine stage); sorting the collection of data objects (Sorting Processor stage); generating the UI Layout (Layout Generator stage);  propagating UI changes back to the Data Model having the definitions of the data objects (Data Dispatcher stage); propagating data changes to the Repetitive Layout; and propagating changes to nodes of the data model.

IPC: C12N15/11
Filed: 2003-10-17
Abstract: A polymerase protein originating from a eukaryotic cell and involved in the RNA silencing pathway is for the first time provided in a purified soluble form that possesses a detectable RNA polymerization activity. This polymeras e is useful in methods and kits for in vitro RNA synthesis. A polymerase of th e invention copies ssRNA templates to produce two types of reaction products: short and long RNA copies. It can also copy ssDNA templates. The polymerization does not require a primer for the initiation of RNA synthesis , although RNA synthesis can be also initiated in the presence of a primer. In addition to standard nucleotides polymerase of this invention also accepts a number of modified nucleotides. The polymerase is useful in many downstream applications such as production of labeled RNA probes or generation of trigg er RNA molecules to induce RNA interference effects in living cells or suitable in vitro systems.
