Abstract: A progressive former and method of producing progressive formers is disclosed in which the bed frame is formed of two side frame members and a spacer member. The two side frame members and the spacer member are substantially fully machined before the side frame members are assembled on opposite sides of the spacer member. Within a given machine size, the side frame members are identical and the width of the spacer member is adjusted to provide the proper spacing between the side frame members for the particular number of work stations in a given machine. By utilizing component parts to produce the machine bed frame rather than a one-piece casting, substantial cost savings are achieved. Further, since the side frame members are identical in machines of a given size having different numbers of work stations, it is economically feasible to produce side frame members for inventory and then assemble them with an appropriate spacer member to provide the desired number of work stations.

Abstract: A detection or safety system is disclosed for preventing leakage of harmful gases when fragile ampoules break during heating of components in crystal growth experiments. In the preferred embodiment, the system includes an inner silica ampoule to house the components and reaction product; an outer silica ampoule that encases the inner ampoule, leaving a gap between them; an inert gas (preferably neon) that is normally trapped in the gap; and a metal canister that houses or contains the ampoules. If the pressure becomes too great within the inner ampoule, during heating by the crystal growth furnace, both ampoules may break. If that occurs, the neon is released, where upon its presence is sensed by a thermal conductivity detector ("TCD"). The TCD then sends off a signal to a controller which shuts off the furnace power. The resulting decrease in temperature releases the pressure and prevents the canister from being breached.
