Abstract: A heat exchanger assembly comprises a heat exchanger for heat exchange between at least a first heat exchange fluid and a second heat exchange fluid. The heat exchanger comprises at least one heat transfer element delimiting a first fluid path from a second fluid path, and a through connection for the first heat exchange fluid arranged at a first side portion of an outer structure of the heat exchanger. The assembly comprises a pressure pulse damping apparatus comprising an elastic element, and a first conduit leading to the elastic element. The first conduit comprises a first opening connected to the through connection of the heat exchanger such that the first conduit is fluidly connected with the first fluid path. The elastic element fluidly communicates with the first fluid path only via the first opening. There is further disclosed use of a pressure pulse damping apparatus comprising an elastic element.

Abstract: A contact lens mould for producing a contact lens. The mould comprises a first mould half having a convex moulding surface of predetermined curvature, and a second mould half having a concave moulding surface of predetermined curvature. The first mould half is provided with an annular abutment surface which circumferentially surrounds and is contiguous with the convex moulding surface, and the second mould half is provided with a flexible annular lip which circumferentially surrounds the concave moulding surface.

Abstract: The present invention is directed towards a window sill flashing comprising a base having a substantially rectangular shape. A front flange projects perpendicularly downward from a front edge of the base and at least one side flange extends vertically from a side edge of the base. The side flange includes a front surface. The window sill flashing is made from a rigid homopolymer vinyl film.

Abstract: A contact lens is provided that has visible inversion marks on the lens. The marks include a plurality of recessed spots having side walls, a substantially convex bottom surface, and a relatively shallow maximum depth of between about 7.5 microns and 12 microns. The recessed spots provide a highly visible marking indicia on a contact lens with maximum comfort to wear. A method is also provided to make the inversion marks. The method includes projecting one or more laser beam pulses through a laser beam mask to etch an array of recessed spots in a surface of a contact lens mold insert and then scanning the insert and mask synchronously with respect to the laser beam pulses thereby forming the inversion mark on the mold insert. The mold insert is used to make casting cups for cast-molding contact lenses, through which the inversion marks are reproduced on the contact lenses.
