Abstract: The equipment includes a vertical guide tube (1) with an inlet (G) for the insertion of cups, and a waste bin in which they are received. The cup passes detection bars (IR1-3) to monitor its passage through the chute, which is used for collection of cups after vending of drinks. The collection equipment comprises a guide tube (1) which is mounted vertically, or nearly vertical with an inlet (G) for the insertion of cups, and a waste bin in which they are received. The tube is of a diameter to ensure that the cup is guided down in the upright position, falling into the waste bin at the bottom. The cup includes an invisible marking, formed with an ink which is not seen under normal white light, but may be detected under IR light. The cup passes a first detection bar (IR1) near to the inlet (G), and then passes a light transmitting source (LL) and a light detector (LD) so that its passage can be read. the cup finally reaches two further detectors (IR2 and IR3) near to the bottom of the chute. A pivoting finger (D) controls the access to the tube just beneath the inlet (G).

Abstract: On the premise that a target torque of an engine is equal to 0, that observed catalyst temperature is in a specified temperature range causing deterioration of the catalyst, and that the engine runs idle without a fuel cut regardless of fulfillment of preset fuel cut conditions, the control procedure of the invention determines whether a predetermined engine stop condition is fulfilled (step S 300 ). Upon fulfillment of the predetermined engine stop condition, the control procedure subsequently determines whether a high load is applied to an exhaust catalyst (step S 320 ). The engine runs idle (step S 310 ) when a high load is applied to the exhaust catalyst. The relatively low-temperature exhaust gas from the engine in the idling state forcibly cools down the exhaust catalyst. This prevents the exhaust catalyst from being kept at high temperature. When a low load is applied to the exhaust catalyst at step S 320 , on the other hand, the engine is stopped (step S 330 ). The stop of the engine cuts off the air flow through the exhaust catalyst. The exhaust catalyst is thus not exposed to the lean exhaust atmosphere and does not significantly deteriorate even at high temperature.
