Abstract: A head assembly for a pultrusion process for pultruding pultrudable material is provided. The head assembly includes a floating adjustable assembly carrying a pultrusion die. The die has a center line disposed proximate the center line of the process and an entrance, and an exit. The material passing from the entrance to the exit of the die in forming an acceptable finished shape is maintained when formed with the center line of the exit of the die always remaining stationary and disposed proximate the center line of the process.

Abstract: A closure assembly is provided assembled from framing sections being fiberglass pultrusions having thin walls, sufficiently thin so as to require reinforcing of the pultrusion proximate the ends and at predetermined positions to allow for (i)joining adjacent pultrusions together and (ii) assembling hardware to the pultrusion, (iii) mounting the pultrusions when assembled in an opening.

Abstract: A sliding patio door assembly is disclosed of the kind in which the door, when it is being closed, moves bodily laterally with respect to the slide track; i.e., forwardly with respect to the closing door panel. When fully closed, the door is entered into a recess, and a weather seal is compressed between the door and a lip surrounding the recess. The door is controlled, as to its lateral movement relative to the slide track, upon crank arms, and it is a feature of the disclosure that the crank arms are constrained to pivot in unison but in opposite senses of rotation. Another feature is that the crank arms lie at 90 degrees to the line of the slide track when the door is fully closed.

Abstract: A sliding door panel is provided which moves bodily into and out of a recess so as to be closed or open, and when out of the recess it may be rolled sideways clear of the recess for ingress or egress therethrough. The moveable door panel is provided with a pair of crank shafts which carry crank arms, and one mounted so that rotation of a door handle causes rotation of the crank shafts and arms. The crank arms are each fixed at one end relative to the door, and at the other end relative to a track so as to cause the bodily movement of the door. The crank arms are also co-operatively associated with latch bars which enter latch slots at both the mullion and jamb sides of the door, so as to assure positive, intruder-proof latching of the door panel when closed.

Abstract: This sliding door as disclosed is of the kind where the door moves sideways relative to the slide-track and into a recess, upon closing. The door is mounted on crank-arms, which are turned by means of a door-handle. As disclosed, the door handle also includes a latch. A first part of the motion of the handle unlatches the latch, and subsequent part of the motion of the handle turns the crank-arms. This sequence makes it possible for a further latch to be provided on the mullion side, which can be also operated by the door handle.

Abstract: A moveable, rollaway door or window panel is provided in a structure having one moveable panel and one fixed panel. The moveable panel, when in its closed position, is substantially co-planar with the fixed panel; and when in its fully open position, it is substantially co-extensive with and on the interior side of the fixed panel. A pair of control rods, one at each side, is concealed within the sash structure of the moveable panel, and is secured at its top and bottom ends to a cam member. Each cam member has a guide member which co-operates with a guide track, and is rotatable with respect thereto. The cam members at the upper ends of the control rod are connected to each other by a tie rod or cable in such a way that rotation of one of the control rods causes an equal rotation in the same direction of rotation of the other of the control rods, thereby assuring planar movement of all four corners of the moveable panel.
