Abstract:
A steel alloy for fabricating into chain links particularly for a mining chain having a composition including nickel in the range of 0.3 to 1.5%, particularly 1%, chromium in the range of 0.2 to 1.0%, particularly 0.5%, molybdenum in the range of 0.1 to 1.0%, particularly 0.75%, carbon in the range of 0.15 to 0.28%, particularly 0.23%, vanadium in the range of 0.05 to 0.2%, particularly 0.1%, and the balance iron. The steel alloy enables the fabrication of mining chain having an acceptable stress corrosion resistance to aggressive conditions likely to be encountered in mining without sacrificing hardness and strength in comparison with a conventional composition steel chain.
Abstract:
The present invention provides a pressure controlled wind turbine enhancement system which includes a two part conical shroud to be located directly upwind of a turbine in order to augment the natural flow of air past blades of the turbine in a manner which produces increased power output from the turbine.
Abstract:
The present invention is concerned with a system and method for enhancing the performance of a wind turbine, which involves injecting air from an array of nozzles into the airflow upstream of the turbine in order to reduce the turbulence and/or increase the velocity and/or control the pressure of the airflow, thereby improving the performance of the turbine.
Abstract:
A utilities pod (10) for a vehicle, especially a caravan. The pod is removably mounted underneath the cabin structure and contains utilities apparatus such as a water heater, space heater (62), battery and water tank (60). The pod is connected to the cabin of the vehicle by an interface unit having multiple ports (18) by which said respective utility services are provided to the cabin. The interface unit is configured for installation in the floor of said cabin such that the ports are exposed to the interior of the cabin structure.
Abstract:
A solar cell and alternating low voltage electrical transmission system assembly having a curved solar cell panel supported on the side of an electrical transmission pole partially wrapping around the pole, and held in a spaced apart relationship by having upper and lower spacing blocks which are also held to the pole by in each case a strap.
