Abstract: A sill drainage member for a window assembly which can include at least one sash. The sash includes a window pane in a frame which can be a single or double glazed window. The sill drainage member has an elongate body with an upper surface and lower surface. The upper surface includes drainage means which is adapted to drain moisture from a window sash. The sill drainage member is adapted to be located and fixed underneath a window sash. A method of installing the sill drainage member with slope blocks and double glazing units is also included and a method of retro fitting double glazed units in wooden sashes.

Abstract: Embodiments of a system and method for distributing network data to multiple nodes in a data communications network is described. Two data communication channels are provided for each node in the network. While one of the communication channels carries routing and flow control protocol messages, as well as data, in both directions between network nodes, the other communication channel is configured to transmit data traffic—and only data traffic—in a single direction from the network data server toward all of the other nodes in the network. By using 100% of the available bandwidth for data traffic only, the speed at which data may be distributed throughout the network is maximized and the performance degradation caused by the congestion, collisions or packet loss that typically occurs in two-way data communication channels is avoided.

Abstract: To prevent seal failure in internal combustion engines, blow-by gasses leaking past the piston rings require venting. However, moving engine components cause airborne oil particles to be mixed in with the gasses. Depending on breather system and engine type, oil carry-over can cause increased operating costs, reduced engine performance and emissions issues. The present invention provides a simple and inexpensive barrier device fitted in a cylinder block. The device is positioned such that oil particles impact on the device and coagulate to form droplets which subsequently run back to the crankcase. Some advantages provided by the present invention are that the engine envelope is unaffected, the barrier device is the only additional part, and the cylinder block requires no or minimal adaptation.

Abstract: A hollow air filled flexible horizontal endless plastic waterproof loop floats on top of the water in a swimming pool and is shaped to conform with and bear continuously against the inner periphery of the pool. The loop has an open central region. A thin flat flexible horizontal plastic waterproof sheet is disposed in the region to close same and is sealed at its periphery to the loop.
