In a gas turbine combustion system, liner stops mount a combustion liner within a flow sleeve. The liner stops are mounted on the outer surface of the combustion liner and the inner surface of the flow sleeve in a symmentrical array of liner stops. The liner stops have inclined contacting surfaces that support the liner within the sleeve, and provide rubbing contact between the two. These inclined surfaces are on a post of a male liner stop that fits into a channel of a female liner stop.

A piano key cover having a body of synthetic material pigmented to resemble natural ivory defines a top playing surface having a random orientation of peak-to-valley texture and a multiplicity of fine pores to replicate a surface of natural ivory. A multiplicity of the pores have diameters generally in the range of 0.0002 to 0.0012 inch (0.005 to 0.030 mm). The synthetic material is selected from the group consisting of acrylic polymer, polyurethane, epoxy and the like. A method for forming such a piano key cover and a piano having key covers of the invention are also described.

A piano key cover is formed of synthetic material pigmented to resemble natural ivory and having a top playing surface with a random orientation of peak-to-valley texture and a multiplicity of fine pores replicating natural ivory. The key cover is formed by providing a mold, engraving a surface of the mold with a randomly-oriented pattern of peak-to-valley texture replicating natural ivory, placing in the mold a composition of suitable synthetic material pigmented to resemble natural ivory and filler, the filler having the characteristic of being removable from a molded article by further treatment, forming the piano key cover within the mold, and treating the piano key cover to remove the filler thereby causing the surface of the paino key cover to define a plurality of fine pores replicating the surface of natural ivory. A piano including the key cover of the invention, and formed by the above method, is also described.
