Title: Retro-reflecting sheet material and method of manufacture.
IPC: B32B15/08
Filed: 1979-09-20
Abstract: The specification relates to retro-reflectors of the type used for road signs and markers and vehicle license plates to make these objects more noticeable to road users after dark. In the invention, the surface of a metal substrate is made retro-reflective by applying a layer of an organic polymeric material and adhering glass beads thereto, and then passing the substrate through a roller mill or the like with the glass beads covered by a platen so that the beads form indentations in the metal surface. The presence of the platen allows the pressing (indentation) step to take place without damage to the glass beads or to the layer between the beads and the metal surface. By this means, a hard metal article can be made directly retro-reflective.

Title: Furnace for firing heavy ceramics
IPC: F27D3/00
Filed: 1983-03-29
Abstract: A furnace for baking heavy ceramic articles has a threshold attached to the chassis of the furnace by a series of curved, articulated connecting rods. A motor-driven eccentric moves the threshold in a downwards and backwards direction, with tilting of the connecting rods until their lower extremities meet an associated spring. The eccentric then produces a sudden release of the threshold, with recovery in an upwards and forward direction by the action of the springs, and this is of sufficient amplitude to cause a slight displacement of the articles w.r.t. the threshold and a resulting advance over it.
