  • Coating material and application methods therefor
    Patent number: 6395345
    Abstract: A coating material of a modified, climate resistant wax substance, which is applicable in melted condition, has been found to be perfectly applicable not only from an already melted wax bath, but still better if it is used in the form of a powder that can be injected into a blowlamp flame or a flow of hot air. A possible technique for making the powder is disclosed. Smaller articles may be “wax painted” by receiving, in heated condition, a surface layer of the powder.

  • Device for controlling the peripheral speed in rotating objects
    Patent number: 4097787
    Abstract: In order to control the peripheral speed of a rotating object, such as a grinding wheel, the current of the motor driving the grinding wheel is periodically integrated during a deceleration and an acceleration to obtain a composite signal from the integrator which reflects the necessary change in speed due to the decrease in diameter of the grinding wheel, which correction signal is combined with a signal representing a control input for a maximum size and supplied to the controller for the grinding wheel motor.
