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: A truck trailer door-activated air brake release lock system for use with spring-set air-release vehicle brakes.

Abstract: A system for sensing the flow of an electrically conductive liquid through a nozzle. The nozzle represents one side of an electrical sensing circuit. A conductive probe is positioned near the nozzle, so that it extends into the spray. The probe represents the second side of the electrical sensing circuit. The probe is mounted on a clamp positioned on the inside of a protective enclosure. The probe is the bottom of the enclosure. When liquid sprays from the nozzle, the sensing circuit is closed. A switch responds to this by illuminating an indicator lamp. If the liquid flow ceases, the signal circuit is opened, and the switch signals this occurrence. The switch is a transistor that operates a light emitting diode.
