Abstract: The disclosure embraces a method of and apparatus for processing bodies or tiles such as surfacing tiles fashioned of compressed mineral fibers bonded by a cured binder wherein the bodies or tiles are arranged in stacked or nested relation and the bodies or tiles individually and successively detached or separated from the bottom of the stack and advanced through processing stations at which the bodies or tiles are subjected to finishing operations whereby the bodies or tiles are configurated to substantially uniform size and shape.

Abstract: The disclosure embraces a charge forming apparatus or carburetor and method of operation thereof wherein the charge forming apparatus is of modular construction comprising a body construction and a fluid flow control system including a laminar means or member having perforate fuel conveying regions including a channel for conveying fuel from a fuel chamber to an engine idling and low speed orifice system in association with a passage arranged to receive pressure pulses from the engine crankcase under open throttle conditions for discharging fuel in the channel through an aperture means independent of the main and engine idling fuel delivery aperture means into the air induction system of the charge forming apparatus for engine acceleration purposes, the fuel conveying channel being of substantial length and of a cross sectional area to effect delayed fuel flow to the engine idling system to avoid formation of an overrich mixture which would result in stalling the engine.
