Abstract: A combined float bowl carburetor and fuel pump for small engines has a lateral extension on its carburetor body that terminates at a flat exterior surface to which open certain cavities and a passageway leading to the float valve inlet. A block-like pump body having flat inner and outer surfaces overlies said exterior surface and has cavities opening to its inner surface that cooperate with those in the carburetor body. A resilient pump membrane, providing a pump diaphragm and valves, is confined between the pump body and said exterior surface. Two cavities open to the outer face of the pump body, which is overlain by an imperforate resilient membrane to define inlet and outlet surge chambers that are respectively communicated with the pump by way of the inlet and outlet valves. All cavities, inlets and outlets are arranged to ensure maintenance of a consistent head of fuel at every inlet.

Abstract: The actual temperature of the extrudate issuing from a long land die extruder is measured and a measurement signal representative thereof is established. The measurement signal is then compared with a setpoint signal representing the desired extrudate temperature to produce a control signal which is responsive to the difference between the measurement signal and the setpoint signal. The cooling fluid being circulated in heat exchange relationship with the extrudate in the long land die is manipulated responsive to the control signal to maintain the actual temperature of the extrudate substantially at the desired extrudate temperature. When the magnitude of the difference between the measurement signal and the setpoint signal exceeds a predetermined value, the rate of heat input to the plasticization section of the extruder and/or the rate of extrusion of the extrudate can be varied to reduce said difference to less than said predetermined value.
