    Abstract: A nozzle arrangement comprising concentric inner and outer cylinders and a jacket fitting tightly around the outer cylinder. The inner and outer cylinders have longitudinal fluid exits and are relatively rotatable. A knob located outside the outer cylinder is connected by a shaft to the inner cylinder to permit it to be rotatably adjusted relative to the outer cylinder. The jacket has an elongated slot that serves to regulate the flow through the exit of the outer cylinder.

    Abstract: A machine and method are disclosed for inserting the leads of electrical components through holes in a printed circuit board. Included in the machine are assemblies for selecting one of a variety of different kinds of components and selecting the location on the circuit board at which the selected component leads are to be inserted. Preparatory to insertion, the leads of the selected component are straightened, cut, and chamfered on a component block assembly. The circuit board is mounted on a backplate having longitudinal grooves with inwardly sloping sidewalls that bend the leads after insertion through the circuit board.
