Abstract: A boot with studs built into the sole and heel sections to afford the wearer maximum traction in snow, sleet and ice thereby preventing slippage and possible injury to the wearer during execution of required duties.

Abstract: This invention relates to apparatus for conveying bulk materials, such as minerals, down a vertical or steeply inclined path of descent. An endless conveyor carries the material downwards by gravity, and at the same time drives an energy transformation unit, such as an electrical generator. The conveyor also drives an air compressor, which feeds compressed air to a reservoir. Air from the reservoir can drive a turbine for maintaining the speed of rotation of the generator in the event of a decrease in the conveyor speed. The speed may be monitored by a govenor. The compressed air may also drive apparatus for excavating the minerals. The material may be delivered to the conveyor by a succession of trucks on a circular track layout, which is inclined to the horizontal, the trucks moving towards the conveyor under gravity.
