Abstract: Disclosed is a warm window system that utilizes individual buss bars that are placed within the space between an inside window pane and an outside window pane and creates sufficient physical force to create an electrical contact on the tin oxide layer on the inside surface of the inside pane of glass. The buss bars have a modulus of elasticity to ensure sufficient electrical contact with the tin oxide layer to prevent the formation of hot spots and securely hold the buss bars in place. Both a z buss bar and c buss bar are also disclosed that are capable of generating a sufficient amount of reactive force to create a secure contact with a tin oxide layer on the interior surface of an interior pane of glass in a warm window system to hold the buss bar in place and provide a large contact surface area to provide sufficient electrical contact with the tin oxide layer to prevent hot spots.

Abstract: Disclosed is a multi-coil spring assembly that is mounted in the weight pocket of a vertically operating window. The multi-coil spring assembly allows the user to attach a desired number of multi-coil springs having chosen constant forces to the counterbalance connector to provide the desired amount of counterbalance force to the sash of a vertically operating window. The multi-coil spring assembly may be rotated into an interior portion of the window to permit straightforward attachment to the counterbalance connector and then retracted into the weight pocket in a recessed position for normal window operation.

Abstract: Disclosed is a two part hook and loop weatherstripping system in which one portion, such as the hook portion that is attached to a window frame and another portion such as the loop portion that is attached to the hook portion and includes a flexible material that may be compressible to provide a seal between a window sash and the window frame. The removable portion can be easily removed and cleaned or replaced with a new portion. Different thicknesses of the removable portion of the hook and loop weatherstripping allows various size gaps between a window frame and a sash to be easily filled. The use of two part hook and loop components incorporating a weatherstripping system provides for the components to be utilized in such a way so as to provide an overlap joint at all corners that restricts linear shrinkage and eliminates the holes that commonly materialize at the corners from shrinkage of single part weatherstripping systems.

Abstract: Disclosed is a multi-coil spring assembly that is mounted in the weight pocket of a vertically operating window. The multi-coil spring assembly allows the user to connect any desired number of coil springs to the counterbalance connector to provide the desired amount of counterbalance force to the sash of a vertically operating window. The multi-coil spring assembly rotates into an interior portion of the window to allow simple and easy connection to the counterbalance connector and then retracts into the weight pocket in a recessed position for normal operation.
