Abstract: A window spacer for integrated glass units is disclosed. The window spacer has an elongated housing with two distal ends. The housing is bent upon itself so that the distal ends are adjacent to each other. One end has an engaging slot, and the other end has an engaging member formed in it. When the engaging member is inserted into the engaging slot, a restraining portion of the engaging member prevents the engaging member from disengaging from the engaging slot.

Abstract: A rotary punch includes an upper die plate, a lower die plate, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway. The lower die plate is connected to the support frame for movement in a linear horizontal direction only. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods attached to the upper die plate that extend down through bushings provided in the lower die plate. In operation, the lower die plate horizontally follows the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper plate moves towards and away from the lower plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.
