Abstract

Apparatus for detecting the presence or absence of the surface of a toughened glass sheet or windshield comprises inner and outer tubes 1, 2 defining an annular nozzle 3. Fluid under pressure is forced radially into the space between tubes 1, 2 by a pump 15 (Fig. 3, not shown) and the back pressure in tube 1, which varies with the position of the surface, is measured by a pressure sensitive device 16, e.g. a pressure switch, a pressure transducer or a manometer. The apparatus shown in Fig. 5 forms part of an apparatus for testing toughened glass 23 moving on a conveyer 21. The jet nozzle 26 of the device detects the leading and trailing ends of a sheet of glass 23, the change in pressure operating a pressure switch 30 with a central contact arms 31. A control device comprising a uniselector 32 responsive to the pressure switch 30 and connected to pulse generating means comprising an eccentric cam 33 driven at a speed proportional to the conveyer 21 carrying the sheet 23, controls a percussion impact means 25 and causes it to subject the central part of the glass sheet 23 to an impact to test that it has been sufficiently toughened. <PICT:1029826/C1/1> <PICT:1029826/C1/2>
