An arrangement for testing a photomask (2) for defects, includes two identical lens systems which produce respective images of portions of the photomask on rows of photosensors (15, 16). Signals from the photosensors are compared to indicate defects in the photomask. Two further rows of photodetectors (13, 14) are provided for determining positional errors of the image formed on the photosensor ro...

1. Aerosol packaging with an upper chamber (9) receiving a first component (A) substantially free of pressure as well as with a lower chamber (10) receiving a second component (B) together with a quantity of propulsion gas under pressure and substantially sufficient for the expulsion of the component mixture (A, B), with a connecting channel (16) between the chambers, which is to be opened with th...

The non-invasive instrument for measuring the rate of blood flow in capillary blood vessels incorporates a laser generator 16 which transmits blue light to a beam splitter 20 and to a single optical fibre 32 with a small diameter core (50 mu m). The small penetration depth of the light and the small diameter of the fibre enable a measurement to be made on a small number of capillary loops so that...

A digging wheel for a suction dredger vessel which digging wheel rotates about a horizontal axis and has at its circumference a plurality of closely spaced partly overlapping scoops while the suction mouth in the interior of the wheel has an extension which extends into the scoops and fits through the outlet of the scoops. The effective passage between the leading edge of a scoop and the outlet ed...
