摘要:
The invention provides a method of moulding a vision correction lens from a transparent resin. The resin is introduced into a mould cavity, the sides of which cavity which correspond to the front and rear surfaces of the lens being formed by two sheets, at least one of which is flexible. The amount of resin in the cavity is adjusted to deform the flexible sheet(s) so that the shape of the lens defined by the sheet(s) will provide a desired power, and the resin is then cured. The sheets can be transparent, and a user can look through them as the amount of resin is adjusted, to ensure that the lens is of the desired power. Further, the amount of resin in the cavity can be adjusted to accommodate changes in the refractive index of the resin as it cures.

A wicker repair tool lands on a casing hanger within a wellhead. The wicker repair tool engages cutters with the inner diameter of the wellhead and rotates to reform wickers in the wellhead. The wicker repair tool includes a tubular member having an upper end that couples to a tubing string. A tubular tool head is formed on a lower end of the tubular member. At least one cutter is coupled to the tool head and is radially moveable between an engaged and a disengaged position. The cutters are adapted to engage an inner diameter surface of a wellhead so that rotation of the tool head relative to the wellhead will reform the wickers.

The invention relates to a variable focus lens (10), comprising a rigid ring (22), a flexible membrane (20) attached to the front surface of the ring, a rigid transparent front cover (40), attached to the flexible membrane (50), and a rigid rear cover (20) on the rear surface of the ring (22). A cavity (60) is formed between the flexible membrane (50) and the rear cover (20), and the cavity is filled with a liquid. The amount of liquid in the cavity can be varied to vary the curvature of the flexible membrane and so vary the optical characteristics of the lens. The rear cover can be integral with the ring, or formed separately. Further, a second flexible membrane can be positioned between the rear cover and the ring. The various parts of the lens can be held together by adhesive.

The invention provides a variable focus lens, comprising a ring with a front surface and a rear surface. A flexible membrane is held between the front surface of the ring and a generally rigid transparent front cover, and a rear cover is attached to the rear surface of the ring (optionally with a second flexible membrane sandwiched between the rear cover and the ring). A cavity is formed between the flexible membrane and the rear cover (or the second flexible membrane) is filled with a liquid, and the amount of fluid in the cavity can be varied to vary the curvature of the flexible membrane and so vary the optical characteristics of the lens. The ring of the lens may be coloured, and may be transparent, translucent or opaque. Alternatively, a decorative cover may be attached to the front of the ring to give the appearance of a frame. The lenses may be used in variable focus spectacles.

A method and system of providing telephone service comprises associating a list of telephone numbers with a representative telephone number. A call to the representative telephone number is detected and a plurality of telephone numbers on the list are simultaneously signalled. Thereafter, signalling is terminated at at least one of the plurality of telephone numbers thereby allowing a connection to be established with one or more parties at telephone numbers among the plurality of telephone numbers. Each telephone number on the list may be a representative number which is associated with another list of telephone numbers.
