Abstract
Abstract Process for forming a series of spaced, generally uniform, curved grooves of tapered configuration in a surface of a bar intended for use in a fluid bearing track structure or the like, and the grooved bar which results from utilizing such process. Material is cut or ground from the bar surface by a rotary cutter or cylindrical grinder, the axis of rotation of which is set at compound angles and is inclined in the direction of movement of the bar and also in a direction transverse to such direction of movement. Each of the curved grooves progressively decreases in depth and width from one end thereof towards its other end to define a nozzle configuration. In the preferred embodiment illustrated, the bar being grooved is moved continuously beneath a continuously rotating cutter.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
116 words
A fluid bearing track structure or the like, comprising A. a grooved bar having a generally planar surface, B. a series of spaced generally uniform grooves in said surface, 1. said grooves being curved and extending across said surface, 2. each said groove being larger at one end thereof than at its other end, whereby such groove is generally in the configuration of a curved nozzle, and C. a back up bar engaged with said grooved bar in contact with said surface and closing off said grooves therein except at said ends thereof, whereby fluid introduced into each of said grooves through said one end thereof may pass therethrough and emanate from said other end thereof.
Claim 2
Dependent Claim
116 words
A fluid bearing track structure or the like, comprising A. a grooved bar having a generally planar surface, B. a series of spaced generally uniform grooves in said surface, 1. said grooves being curved and extending across said surface, 2. each said groove being larger at one end thereof than at its other end, whereby such groove is generally in the configuration of a curved nozzle, and C. a back up bar engaged with said grooved bar in contact with said surface and closing off said grooves therein except at said ends thereof, whereby fluid introduced into each of said grooves through said one end thereof may pass therethrough and emanate from said other end thereof.
