Method and Apparatus for fabricating a spacer frame for use in an insulating glass unit. One of a multiple number of possible spacer frame materials is chosen for the spacer frame. An elongated strip of the material is moved to a notching station where notches are formed at corner locations. The character of the notches is adjusted based on the selection of the metal strip material and more particularly to achieve bending of the material hi an repeatable, straightforward manner. Better control over the notching process is also achieved by exhaust row control of a double acting cylinder. A positioning spacer achieve very accurate side to side positioning of a die and anvil to precisely notch and deform the metal strip. Downstream from the notching station the metal strip is to bent into a channel shaped elongated frame member having side walls. Further downstream leading strip of channel shaped material is severed or separated from succeeding material still passing through the notching and bending station.

A method for producing a pattern of depressions in the friction surface of a friction component for a frictionally operating device, preferably a multiplate clutch or multiplate brake. After the preparation of the friction component, the pattern of depressions is produced by nontraditional material removal, removal of material preferably being accomplished in a contactless manner, particularly preferably with the aid of a laser beam.

An apparatus for forming a firtree slot in a disc of a bladed rotor assembly for a gas turbine engine may include a tip portion having the shape of the profile of one side of the firtree slot to be formed but smaller than the profile of the complete firtree slot so that the tool will only engage one side of the firtree slot.
摘要:
A method for producing a cellular wheel, wherein a tool having a cylindrical inner shell, the diameter of which corresponds to the inner diameter of the subsequent sleeve, is placed on the free end edges of the fins for fixing the angular orientation of the fins. A molding material mixture is applied in the cells bounded by the inner shell of the tool and the fins and cured. After removing the tool, the subsequent sleeve is placed on the free end edges of the fins fixed in place by the cured molding material mixture. The free end edges of the fins are joined to the subsequent sleeve to the cells. The cured molding material mixture is thermally treated and is removed from the cells.

A method of carving a contour surface on a composite core can include positioning a first edge of the composite core against a first tooled member; locating a first magnet within an outer cell member along the first edge of the composite core so that the first edge of the composite core is magnetically drawn to the first tooled member; locating a second magnet along a second edge of the composite core such that the second edge of the composite core is magnetically drawn to a second tooled member; and carving a first contour of the composite core.

A gas turbine engine preswirler (470) includes an outer ring (471) and an inner ring (472). The inner ring (472) includes a plurality of angled holes (490). Each angled hole (490) follows a vector which is angled in at least one plane. A component of the vector is located on a plane perpendicular a radial from an axis of the preswirler (470). The component of the angle is angled relative to an axial direction of the preswirler (470).
摘要:
A coupling for a molten metal processing system to provide coupling for rotor/shaft systems which has a heat break to prevent heat flow to a motor. A cross sectional area reduction provides a restriction which reduces heat transmission through a conductive material to restrict heat flow to a motor, which will ultimately extend the life of the motor.

Assemblies and methods for processing a workpiece in a ram-driven press employ an active tool contained by a housing that is interchangeable with a passive forming tool assembly in a mounting assembly of the press. The active tool includes a microprocessor and a functional head coupled to the microprocessor. Some assemblies including the active tool include a switch for activating the functional head; the switch may be mounted to the housing such that, when the housing is mounted in the mounting assembly of the press, the switch is triggered by movement of the housing in response to the ram stroke of the press.
