Abstract: A frame section for a window frame or a door frame structure includes at least one roll-formed frame member of substantially L-shape in cross-section which may be combined with other identically shaped and sized frame members to form Z- and T-shaped configurations. Each section has an open dovetail channel capable of receiving a glass molding member for supporting a window pane or door pane against an opposing abutment wall formed on each section. When sections are combined into the Z- and T-shapes, confronting lips of the sections define grooves for the reception of sealing strips, and weep hole inserts for channeling rain water and condensation from the window unit to the outside may be provided at the corner or corners of the window frames.

Abstract: An apparatus for making transmission belts by assembling a belt sleeve or belt body in the conventional manner and placing them in a vulcanizing chamber. The belt body or sleeve is sandwiched between radially expansible and radially contractable members of the vulanizing chamber. Outward radial pressure is first applied to the belt body or sleeve and then a radial inward pressure is applied. Heat is simultaneously added to cure the body or sleeve.
