Abstract: The invention relates to a device for polishing the edge of a glass sheet. The invention is of the type that comprises: a drive shaft for rotating around the axis of rotation thereof by means of a motor, and a grinding wheel which is connected to the drive shaft in order to polish the edge of a glass sheet. The grinding wheel comprising a groove formed in the outer periphery thereof, which contains a grinding material for polishing the edge of the glass sheet. The grinding wheel is also provided with a plurality of internal passages which extend radially from the centre of the wheel to the outer periphery thereof, in order to enable the passage of a cooling fluid for the cooling of the periphery of the wheel. In addition, a collecting chamber is formed at the centre of the grinding wheel in order to receive and supply the cooling fluid through the passages in the wheel.

Abstract: Coating apparatus for coating a cable with bitumen which is self-contained except for apparatus for supplying a heated fluid to the coating apparatus. The coating apparatus includes a tank for receiving bitumen and has pipes therein to which heated fluid at a temperature sufficient to melt solid bitumen is supplied by external fluid heating apparatus and in which the heated fluid circulates. The cable passes through the apparatus in a trough to which liquid bitumen is supplied by a rotating cylinder partially immersed in the liquid bitumen and connected, for liquid bitumen delivery, to the trough by a pivotable chute. A tiltable cradle receives solid bitumen and dumps it into the tank where it is melted. A wiper in the form of a tensioned, elongate elastic body is wrapped by at least one turn around the cable where it leaves the coating apparatus and an elastic tab engages the cable adjacent the cable inlet to divert liquid bitumen which may flow toward the inlet.
