Abstract: Abstract of the Disclosure:     A manipulative skill game apparatus in the form of a generally upright game board on which are tiltably mounted (in a series extending from the top toward the bottom of the board) a plurality of tiltable, generally horizontally extending platforms.  Structure is also provided for controlling the tilting of the platforms.  The game includes a plurality of balls, and the platforms are in staggered positions from side to side so that a ball rolling off one end of a platform will land on an end of a platform below it.  The object of the game is to tilt the platforms so as to guide a ball from a higher platform successively to lower platforms.  A feeder mechanism automatically delivers the balls one at a time in timed sequence to the uppermost platform.  After a predetermined timed interval the next ball is delivered to that same uppermost platform.  Thus, the player must not only successfully manipulate the tilting of the platforms to guide the ball from higher to successively lower platforms, but he must also race against the clock, remove each ball as quickly as he can from platform to platform, before the next ball is delivered to the top platform.  The further along the path (i.e., the lower down the platform) from where the ball is finally lost, the higher score the player gets.  The feeder mechanism may be selectively pre-set to operate one of several different rates to thereby change the difficulty of the game.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention comprises a fluid distributor which? in a preferred embodiment, comprises an array of parallel rollers rotatably mounted at their ends.  All, or alternate, rollers have a number of peripheral grooves or slots which define, with adjacent  rollers, apertures for the passage of fluid through the distributor.  Suitable deposit-removing means (e.g. in the form of chisel-blades) are mounted either on rollers or separate support members so as to be opposite respective grooves or slots in the rollers and to be receivable in the grooves or slots, so that on relative movement of the grooved or slotted rollers and the deposit-removing means, the latter remove deposited material from the grooves or slots.  The invention is useful in passing deposit-forming fluids (e,g. tarry or dust gases) into fluidized beds supported on the distributor.
