Abstract: A reservoir assembly for retaining a fluid includes a body having a base and external side walls defining a cavity. A baffle has a top surface spanning the cavity and includes a peripheral wall substantially conforming to the external side walls and extending to the base. A lid is connected to the body. The cavity is divided into a first, second and third compartment by a cooperation between the top surface of the baffle, a plurality of walls of the baffle, the base of the body and the external side walls of the body. The first and second compartments are in fluid communication with each other through the third compartment. An inlet port and an outlet port for allowing fluid to enter and exit the cavity are fluidly connected to the body and are fluidly connected to each other by the first compartment to direct a flow of the fluid.

Abstract: A balance assembly (15) is provided for a sash window assembly (10). The sash window assembly (10) has a sash window (12) slidable within a master frame (14). The balance assembly (15) has an elastomer balance member (30) having one end adapted to be connected to the master frame (14) and another end adapted to be connected to the sash window (12) to provide an upward biasing force to the sash window (12). A system (50) is provided for custom-manufacturing the balance member (30) and for custom-manufacturing a sash window assembly (10) incorporating the balance member (30).

Abstract: A muntin clip has a bar support adapted to be connected to a muntin bar end and a base member adapted to be connected to a spacer frame. The bar support has a plurality of flexible support members attached thereto, which are adapted to contact the opposed interior walls of the muntin bar end and deform in response to such contact. The base member has two flexible members forming a flexible latching structure which is adapted to deform when inserted into the spacer frame. The muntin clip to be used with muntin bars and spacer frames having a range of different dimensions and configurations.

Abstract: The present invention provides a spring balance assembly for use with a sash window assembly slidable within a master frame. The spring balance assembly generally includes a plurality of stacked spring assemblies and pivot brake assembly. The spring assemblies include a coil spring and a support plate that rotatably supports the coil spring. Each coil spring has a free end, an intermediate portion, and a coiled portion, wherein the free ends are operably connected to the pivot brake assembly. The coil springs are configured to prevent a portion of the spring from excessive bowing and making prolonged contact with the wall of the mounting channel to which the balance assembly is affixed. In addition, the coil springs are wound in a manner that significantly reduces the occurrence of severe bowing of the coiled portion and engagement with the channel walls. The spring balance assembly of the present invention reduces contact with the channel walls and thereby reduces any friction and the operating force.

Abstract: A radar antenna for a guided missile is calibrated in flight using a point source of microwave radiation and a lens to emulate a far field source. The microwave source and lens fit behind a metal cap at the leading end of the radome and so do not adversely affect the radar.
