Title: Mechanism for separating flexible plies from a stack
IPC: B65H3/22
Filed: 1973-06-06
Abstract: A machine for picking up plies of flexible sheet material to be successively transferred from a stack includes an improved ply separating mechanism enabling an underply to remain undisturbed. The separating mechanism carries and actuates a pick-up device when it has seized an exposed, for instance the top ply, yieldably to rotate the device about an axis substantially normal to the stack while effecting lift-off. The separator and pick-up unit may cooperate with adjacent similar units, counter-rotatable or not, to impart stress in the intervening work piece portions for "peeling" apart and holding them during transfer. The ply separating mechanism is preferably automatically operable at the delivery position to cause work piece release by reason of inertia.

Patent ES-462854-A1 (ES)
Title: Fire resistant window glass
IPC: A62C2/06
Filed: 1977-10-03
Abstract: Fire resistant window consists of >=2 panes of silicate glass sepd. from each other by an air space. Specifically one of the glass panes is of tempered glass while the other(s) are of reinforced glass. The temp. is pref. carried out by ion exchange such that it presents compression stresses due to the tempering exclusively or preferentially in the peripheral regions. The reinforced glass pane is reinforced by a web or mesh of metal wires. By using common soda-lime silicate glass of conventional expansion coefft., the conventional supporting frames can be used without setting up undesired stresses in the tempered peripheral regions, which could lead to shattering during heating in the event of fire. The protections afforded by the special frames in which special glass is needed to match the expansion coefft. is afforded by use of wire reinforced glass.
