Control system, particularly for automatic manufacturing plants

Abstract: The control of the manufacturing process in manufacturing plants requires a multiplicity of sensors and actuators which are usually interrogated and controlled by a stored-programme control, and this requires an electrical connection of each input or output of the control circuit to each sensor or actuator.

The electrical distributor has multiple plug connection which is common to all connection sockets and is connected to the individual connection sockets via electrical conductors.

In addition, the valve is at the same time held by the mounting arrangement.

Axial lead tester/sorter

Abstract: A tester/sorter for performing electrical tests on axial lead devices such as diodes at a very high throughput rate carries the devices on the periphery of a rotating wheel. A contactor assembly periodically makes electrical connection with one or more of the axial lead devices. A flying arm assembly mounts the contactor assembly so that it travels through a closed loop path of motion with respect to the wheel. In a first path portion, mechanical controls acting on the flying arm assembly lower the contactor assembly into electrical contact with the leads of the device. Once in electrical connection, there is no relative motion between the contactor assembly and the leads. After the test is completed, the mechanical controls lift the contactor assembly away from the leads and return it to its starting position. This travel is substantially free of mechanical impacts that could produce vibrations and thereby degrade the accuracy of the testing.
