Abstract: In an automatic-faucet system, the control circuit that operates the system's valve (18) causes an indicator lamp (32) to start blinking when it first opens the valve. It keeps the lamp blinking for a predetermined duration to indicate to the user that a time interval prescribed as necessary for effective hand washing has not yet expired. When the interval does expire, the user is thereby assured that he has complied with the relevant duration regulation.

Abstract: A recess attachment with preset quick change tooling for use on a multiple spindle automatic machine includes a base formed and adapted to be mounted at a work station on an automatic machine. The base is movable in a defined direction during a machining operation and has a slide mounting surface in a plane forming a small acute angle with the direction of movement. A slide is positioned on the slide mounting surface and there are springs attached to the base and the slide inhibiting relative movement therebetween. A tool holder is removably mounted on the slide and there is an adjustment member positioned on the tool holder and a cooperating stop on the slide. The tool holder has a tool receiving opening and there are means for fastening a cutting tool in the opening. The base and slide move in unison to a precutting position.
