Webb2 aug. 2013 · The fundamental electronic structure of the widely used battery material Li x CoO 2 still remains a mystery. Soft x-ray absorption spectroscopy of Li x CoO 2 reveals that holes with strong O 2 p character play an essential role in the electronic conductivity of the Co 3 + / Co 4 + mixed valence CoO 2 layer. The oxygen holes are bound to the Co 4 + … The Pin Index Safety System, or PISS, is a means of connecting high pressure cylinders containing medical gases to a regulator or other utilization equipment. It uses geometric features on the valve and yoke to prevent mistaken use of the wrong gas. This system is widely used worldwide for anesthesia … Visa mer The pin index safety system uses a face seal between the cylinder valve and the associated yoke clamp. There are two holes in specific positions on the cylinder valve body below the outlet port , in positions associated … Visa mer • International (ISO) and European (CEN) Standard EN ISO 407 : Small medical gas cylinders - Pin-index yoke-type valve connections The pin index system is a safety system (PISS) designed to ensure the correct gas is filled into the … Visa mer It is possible to bypass the pin-index system if the pins are removed, damaged or corroded, if extra washers are used, or on some valves with a short face above the orifice, by inverting the gas cylinder. There is one report of the cylinder being painted the wrong … Visa mer Blanking plugs (dummy cylinder heads) can be inserted into empty yokes to ensure that there is no leak out of the yoke when not in use. Visa mer Each gas cylinder has a pin configuration to fit its respective gas yoke. Refer to the diagram for pin numbers; dimensions are in millimeters. • O2: … Visa mer The Bodok seal is a specialised washer that ensures a gas-tight seal between the cylinder yoke or regulator of an anaesthetic machine or any medical device requiring a gas supply, and a Visa mer Medical gas cylinders larger than size E (679 liters) are more likely to be fitted with threaded connectors.
