Accordingly, articles received on the present tranfer station from an incoming conveyor can be discharged therefrom at a right, acute or obtuse angle, in either a curved or straight path, and a control feature can be included with the transfer station whereby horizontal alignment of an article on its vertical axis can be maintained or altered according to preference.

Abstract: A fuel-air mixture regulator for multiple cylinder four-cycle internal combustion engines is positioned between the carburetor and the intake manifold whereby the fuel and air mixture flowing from the carburetor passes through the fuel-air mixture regulator and undergoes an increase in velocity and turbulence enroute to the cylinders for better combustion. The mixture regulator includes a housing having a plurality ports. A thin, resilient, flexible reed for each port is adapted to seat thereover when the engine is not operating and moves away from the port to variably open same for flow of fuel-air mixture therethrough in response to pressure differentials on the reeds during engine operation. The size of the port opening is reduced at lower engine speeds and assures optimum fuel-air mixing and high velocity air flow even at such lower speed.

Abstract: A drafting structure for a multi-section implement having a plurality of interconnected implement sections arranged abreast to a line of draft includes a pair of spaced draft beams extended generally parallel to the line of draft and a pair of spaced spreader beams extended transversely thereto and forming a generally rectangular rigid frame. The frame is mounted over implement center sections and connected to wing sections thereof by hinges that enable folding of the implement for travel and, which when the implement is unfolded and in its working configuration, disperses and distributes the drafting forces and pressures that tend to cause arching of the center sections. Hitch arms are extended from the frame for connection to a prime mover.

The magnets of each cluster are arranged in a radial pattern around a common longitudinal axis and are retained in place by spacers located in intervals along the axis. The maximum width of the clusters is greater than the maximum width of the spacers with which the magnets of the clusters are abutted.
