Abstract: The present invention relates to a cutter bit assembly of the type for use utilized in excavating machines such as in mining, road scarifying, concrete cutting and the like. More specifically, the invention relates to such assembly including a mounting block member having an axial bore extending therethrough adapted to rotatably receive a cutter bit member, and with a polymeric retainer member for preventing axial dislodgment of the cutter bit member during use thereof.

Abstract: A method for controlling the idling speed of an internal combustion engine supplied with a lean air/fuel ratio includes generating a speed error signal. The speed error signal is used to generate a fuel pulse width command signal to control fuel mass charge as a function of the speed error signal. A throttle command signal is generated as a function of the fuel mass charge to maintain a desired air mass charge which in turn maintains a desired air to fuel ratio.

Abstract: A case having two relatively pivotable, open ended case sections that abut at the open ends when the case is in an open position to form a walled, open-positioned to form a walled, open-topped enclosure, the case having a closed position in which the floors in the two sections are disposed parallel and the walls of the case sections extend about three sides of the region between the floors of the case sections. The case further includes a closure panel having a laminar central portion which is moved into recesses in the floors of the case sections when the case is opened so as to avoid forming a blockage between the floors of the two case sections in the open position and which is moved to a position to close the fourth side of the case in the closed position.

Abstract: A method for controlling the idling speed of an internal combustion engine includes generating a constant time delay to determine the delay from the occurrence of top dead center until the next spark plug firing. A speed error signal is applied to the parallel combination of a phase compensator and an integrator to generate a signal for controlling airflow through the throttle of the internal combustion engine.

Abstract: To a breader conveyor there is added a plurality of restrained flow cascading tumbling conveyors positioned to produce roughness of the breading. Slip plates at the terminal portions of the conveyors act to restrain the free flow of the battered and flour breaded chicken until pushed off onto a following conveyor. The breaded chicken in excess flour tumbles from one conveyor to another to produce a rough, flaky breading texture. The breaded chicken is then separated from the excess flour by an output wire conveyor and is fried or cooked in the conventional manner.
