Abstract: Apparatus and process for simultaneously milling, dehydrating and/or sterilizing a material by introducing the material into a chamber comprising rotating instruments while substantially simultaneously introducing a hot gas into the chamber. Gas and material are introduced tangentially to the chamber at points opposed from each other, and the gas and material both enter the chamber in the same direction as the rotating instruments.

Abstract: A vehicle wheel anti-skid apparatus is provided which senses and measures the torque applied to a vehicle wheel, by the road, when the brakes are applied. It uses the wheel torque to power and control the brake thereby limiting the brake friction torque so that it cannot exceed the friction torque capacity of the wheel-road contact, thus maintaining maximum friction coefficients between the wheel and the road and prevent skidding and loss of control of the vehicle.
