The energization circuit comprises a triac which is operated by the output stage in response to outputs from the microprocessor, a manual switch connected in parallel with the triac so that a given electrical load device can be manually activated and a multi-colored LED for indicating the conditions of the input and output circuits individually and in combination.

Abstract: A quick connector for connecting fluid lines includes a first connector having a housing for receiving a spool carrying conduit. The spool sealingly engages an endform on the conduit. At least one seal element and a retainer ring are pre-mounted in a bore in the housing and engage the spool to form a seal between the inner surface of the bore in the housing and the spool and to retain the spool in a fully inserted position in the housing. A method of assembling the quick connector is disclosed in which a stuffer pin is preassembled with the retainer ring mounted at a compressed diameter within a retaining collar on one end of the stuffer pin and the seal element mounted the stuffer pin. The stuffer pin is inserted into the bore in the housing until the seal element snaps into one groove in the bore and the retainer ring engages another groove in the bore in the housing.

Abstract: A two- or a one-step process and composition which coats metal workpiece surfaces (aluminum, copper, steel, stainless steel, etc.) with a thin lubricant film capable of allowing the metal to be deformed at room temperature. The lubricant consists essentially of polymers, dispersants, high molecular weight waxes and insoluble metallic stearates. With some ferrous surfaces, a separate coating layer is simultaneously formed (in the one-step process) or pre-formed (in the two-step process) at the metal interface, acting as a base for the lubricant. The process, after pickling in a mineral acid to remove scale and oxides, comprises the step(s) of immersing the workpiece either once or twice. The workpiece is then dried in a heated, forced air dryer.
