436	Hot-box two-station core blower - suitable for longer cores	FR7219532	1972-05-31	FR2186308A1	1974-01-11
Hot-box core blower has two stations, and can be used for prodn. of relatively long cores which can be stripped without breakage. The water cooled nozzles have tapered ends and can be moved axially to seat in the mould aperture. In the stripping station, the core and top plate are lifted simultaneously by a piston underneath and, when clear of the bottom box, an upper cylinder lifts a cross beam which locates round the edge of the top plate, and lifts this clear of the core.

439	Sand core loosener - employing pressurisable diaphragm to loosen core without damage to core or core-moulding box	DE2304992	1973-02-01	DE2304992A1	1973-08-09	HOFSTETTER HANS-ULRICH
Pressure-actuated device for loosening fragile shaped bodies, esp., sand cores from core boxes, has an expandable member, pref. a flexible rubber diaphragm, at the base of the box. This constitutes a pressure area to which a pressure medium, e.g., compressed air, can be fed through a supply line to raise the diaphragm and loosen the core.
