Appl. No.:

6/106673

International Classification:

E05D 700

US Classification:

49400

Abstract:

This invention relates to a thermal window construction which comprises a fixed frame member and a movable frame or operating sash member. The window is characterized in that the operating sash member includes an outwardly facing glazing surface to which a pane sub-assembly comprising two or more glass lites are connected, the bond between the pane sub-assembly and operating sash being provided by a bead or quantity of silicone interposed between an inwardly directed surface of the sub-assembly and the glazing surface through a laterally open channel, whereby complete filling of the said space may be assured. The overlapping areas of glass and metal bonded by the silicone rubber material are coordinated with the glass expanse and weight in such manner that the stress applied to the bonded areas will not exceed about 20 p. s. i. The fixed frame member includes a flange member which outwardly laps the outermost face of the sub-assembly, a deformable gasket or the like being disposed between these parts, to define a weather-tight seal with said outer face. The assembly includes, in addition, a resilient seal member extending between a thermally isolated portion of the outer frame assembly and engaging and outwardly lapping portions of the movable frame or sash assembly and also an insulating barrier member carried by the movable frame whereby, in the closed position, all portions of the movable frame are isolated from the exterior.

Abstract:

Flash-butt welder in which the piston rod of a pneumatic cylinder is connected to one end of a pivotable lever arm. A pneumatic system sequentially supplies air at two different pressures to the cylinder. Fixed and movable platens, each with a work piece clamping jaw, are fitted onto a unitary shaft which is mounted in laterally spaced and generally parallel relationship with the pneumatic cylinder. The movable platen is moved by the opposite end of the lever arm along the shaft toward the fixed platen. The movable platen includes a laterally extending arm portion for angular orientation of the platen on the shaft. A switch is disposed to be actuated by the lever arm as it advances to a predetermined position which energizes a solenoid valve to supply substantially higher pressure air to the cylinder. An hydraulic cylinder, disposed in spaced parallel relation to the shaft, includes a piston rod engaged with a pivotable linkage carried by the arm portion of the movable platen. The hydraulic cylinder controls the speed of movement of the movable platen toward the fixed platen during flash welding of the work piece.
