Title: Apparatus for removing liquid substances floating on the surface of water
IPC: E02B15/04
Filed: 1971-05-07
Abstract: 1343648 Removing oil slicks from open water RHEINWERFT GmbH 7 May 1971 [19 June 1970] 13702/71 Heading B1D An open vessel whose upper edge is defined by a vertically adjustable ring 1 floats on the water at such a level that oil and some water flows over ring 1, oil and water being withdrawn from the vessel by pumps attached to respective conduits 11, 9. Floats 3 hold the vessel at a suitable level in the water, and ring 1 extends above the surface until the pumps reduce the internal levels and cause it to submerge. Float 5 is attached to valves 7, 17 so that the vessel is cut off from conduit 9 when the oil layer in the vessel gets too thick, water being then drawn through inlet 16 to induce a general flow of floating oil towards the vessel. In Fig. 1, ring 1 is buoyant, slidably connected to vessel wall 2 by means 19, and has a gas inlet 12 and steam heater inlet 13. In Fig. 2 (not shown) a toroidal ring is connected to wall 2 by bellows. In Fig. 3 (not shown) the ring is replaced by a rubber sleeve attached to wall 2 and adapted to bend inwards of the vessel in response to a relatively lower liquid level inside.

Title: Visibility measuring means

Filed: 1975-04-07
Abstract: 1497214 Measuring visibility photoelectrically ASEA AB 7 April 1975 [8 April 1974] 14134/75 Heading G1A To measure visibility, radiation from a source is scanned across a set of angularly spaced reflectors placed at different distances from the source, and the reflected radiation is detected and thresholded to determine which reflectors are visible. In Fig. la radiation from source 10, e.g. a laser, is scanned over reflectors 11; the source includes a beamsplitter 14, Fig. 2a, so that reflected radiation can pass to a detector 15 via mirror 16, lens 17 and filter 18. The source 12 in Fig. 2 emits pulses under control of a clock 24 and a unit 23 which steps the optical transmitter/receiver unit 21 to perform the scan. When the unit 21 has been stepped to a position where it points towards one of the reflectors, a train of pulses is emitted by the source; the detector signal is also a series of pulses which are integrated and compared with a pre-set threshold at 19 to determine whether the reflector is visible or not. The number of the reflectors which are classified as visible is a measure of the visibility.
