An extendable frame jack assembly includes a securing member comprising a first section that slidably engages a second section. In this way the securing member has a telescopically adjustable length for extending across a variety of sizes of window frames. A pair of blocks is each coupled to opposing ends of the securing member to abut the window frame. A pair of cups is each positioned on the first side of the outer surface of a respective one of the blocks. Each of the cups is centrally positioned between the primary end and the secondary end of the respective block. Additionally, each of the cups insertably receives a respective one of the first end and the second end of the securing member.

A housing for a laser processing machine is described to treat work pieces. The housing comprises a dividing wall, which separates a first work space having a first length and a second work space having a second length from one another, a first entrance to allow access to the first work space, a second entrance to allow access to the second work space, a closing device, which is configured to selectively open and close the first entrance and the second entrance and a control unit, which is operatively connected to the closing device. The dividing wall is placeable in an operating position, which is variable among at least a first position, a second position and a third position. The control unit is configured to control the closing device as a function of the operating position of the dividing wall.

An apparatus and method for supporting an object. In one illustrative embodiment, an apparatus may comprise a support structure, a positioning system, and a retention system. The positioning system may be associated with the support structure and configured to position the support structure with respect to a number of linear axes. The retention system may be associated with the support structure. The retention system may be configured to retain a portion of an object and move the portion of the object towards a platform such that the portion of the object substantially conforms to a shape of the platform.
