Abstract: Electronic displays and electronic devices including such electronic displays and antennas are provided for improved transmission of signals through circuitry of the electronic display. The electronic display may include multiple power supply tiles that are separated with non-conductive gaps to reduce circulation of eddy currents induced by the transmission signals. Moreover, voltage supply routing paths within the power supply tiles may be grouped to provide non-conductive gaps within the power supply tiles. Accordingly, the antenna may provide the transmission signals through the electronic display with improved efficiency based on reducing surface currents (e.g., eddy currents) on the electronic display.

Abstract: A gasket assembly is disclosed for use between adjacent flange surfaces which includes a reusable annular base plate having an inner periphery and opposed upper and lower surfaces, and replaceable a spring energized sealing ring releasably retained within the inner periphery of the base plate and including a resilient spring element surrounded by a deformable jacket that extends beyond the upper and lower surfaces of the base plate to conform to surface irregularities in the flange surfaces upon compression of the gasket between the flange surfaces.

Abstract: A block and tackle window balance includes an extension spring and two blocks of pulleys mounted within a rigid channel. A spring coupling connects a free end of the extension spring to the first block of pulleys. The pulleys of the first block are sized in width to center the spring coupling and the free end of the extension spring within the channel. The second block of pulleys are mounted on an axle that is received in slots formed in the channel. A center portion of the axle guides a pulley cord through the second block for exiting the balance.

Abstract: A jamb liner for a window assembly permits tilt-takeout sashes to be assembled to form a standard window assembly without tilt or takeout capabilities. The liner has an extruded body with a pair of channels for engaging the sashes. The channels are interconnected by two webs. One of the webs forms adjacent portions of sash runs, and the other web forms a bow-shaped spring for urging the channels against the sashes.

Abstract: A lock shoe system for a take-out window having take-out jamb liners (10) uses a pair of fins (22) extending laterally outward from opposite sides (18) of a sash pin slot (16) in the jamb liner for supporting lock shoes (30) that move vertically in lock shoe channels (13 and 14) within the jamb liners. The lock shoes have pivotally mounted ramp latches (60) that extend over locking devices and are inclined toward recesses (82) for receiving sash pins (25). When a sash (20) is returned to an operating position between jamb liners (10), its sash pins (250 are moved downward over ramp latches (60), pivoting these aside and releasing the lock mechanism, which snaps the pins into the receiving recesses. This produces an audible sound as each pin is latched in its respective shoe (30) so that the user can tell from the sounds made when the latching occurs that sash (20) is properly latched into each shoe, where its weight is counterbalanced.

Abstract: A lock shoe system for a take-out window having take-out jamb liners (10) uses a pair of fins (22) extending laterally outward from opposite sides (18) of a sash pin slot (16) in the jamb liner for supporting lock shoes (30) that move vertically in lock shoe channels (13 and 14) within the jamb liners. The lock shoes bear against and ride on sash sides (24) of the fins, and the lock shoes have pivotally mounted biter knives (40) that can pivot into biting engagement with a frame side (26) of the fins to lock the shoes vertically in place. Arms (45) of the biter knives are engaged by pins (25) extending from the sash (20) into the slots for holding the knives clear of the fins whenever the sash is in its run. When the sash is removed from jamb liners (10), springs (50) on the lock shoes (30) bias the biter knives (40) into locking position against the force of the counterbalance springs (33), which bias the lock shoes upward.
