Packaging foil comprising a flexible support foil, a top layer of a vinyl polymer and an adhesion promoter or primer between the support foil and top layer, wherein the primer is a mixture of a chlorine or fluorine-containing polymer and an organic compound with at least two isocyanate groups.

A foil cutter including first and second foil cutting means, said first and second cutting means being relatively movable towards each other for foil cutting engagement with the neck of a bottle, wherein, at least one of said cutting means including a pair of pivotally movable cutting members.

In a foil bearing (23) having a plurality of foils (26) disposed in a gap between a rotating member (12) and a stationary mount member (25), a circumferentially extending portion of each foil and a moveable member (27) rotatable with respect to the stationary mount member are provided with magnets (30, 31) so that a magnetic force between these magnets urges the foils toward the rotating member. By rotating the moveable member to vary the relative circumferential position of the moveable member ...

A journal bearing including a plurality of individual foils mounted to one of a pair of relatively rotatable members, and a plurality of undersprings which provide resilient support for the foils. The foils include a transition area defined for example by a step, adjacent the trailing edge of the preceding foil. The use of the stepped foil optimizes the geometry of the air gap profile, and thereby increases the load capacity of the journal foil bearing.

A foil package for polygonal objects having two opposite sides and a plurality of edge faces connecting the same. A first foil member overlies one of the opposite sides. A second foil member overlies the other of the opposite sides and at least one of the edge faces. A cup-shaped third foil member overlies the other side and all of the edge faces exteriorly of and in surface-to-surface contact with the second foil member. The second and third foil members are connected to one another.

A foil journal bearing comprising a housing having an opening to receive the journal of a shaft, and a plurality of foil supports extending longitudinally through the opening. The foil supports having arcuate inner and outer surfaces and are positioned to transversely surround the journal. An endless foil element encircles each foil support in a direction transverse the longitudinal axis of the element to engage and support the journal. Rods are positioned between the outer arcuate surface of ea...

This invention relates to compact, high efficiency foil regenerators for use in regenerative gas cycle (e.g. Stirling cycle, Ericsson cycle, Vuilleumier cycle, Gifford-McMahon cycle, Sibling Cycle and similar) cryocoolers, heat engines, refrigerators and heat pumps. Very thin foil us formed in patterns of slits and slots that produce highly efficient regenerators when the foil is stacked in layers as by rolling it upon itself.

The invention is directed to a shaving foil for a dry shaving apparatus, including a plurality of adjacent polygonal apertures. In the area of the nodal points of intersecting partitions which separate several contiguous apertures, knob-type protuberances are provided on the side of the shaving foil engaging the skin surface.

A pair of relief portions have been provided in a metal foil bearing so as to prevent the metal foil from contacting with the surface of the rotary shaft of the bearing during its high speed rotation. A relief portion is provided either at (1) both the axial ends of the metal foil, (2) on the outer surface of the rotary shaft at the position corresponding to the axial end of the metal foil, or (3) on the outer surface of the rotary shaft at a position further in than the portion corresponding to...

The invention relates to a foil bearing for high speed rotation such as a turbocharger, a high speed centrifugal separator or the like. The foil bearing according to the present invention can form at least three wedge-shaped spaces between the rotary shaft and the top foil along the direction of rotation of the rotary shaft. The rotary shaft can be supported by at least three portions of air sucked in the wedge-shaped spaces so that when the rotary shaft is rotated at a high speed, the axial cen...
