Title: Removal of oil from the surface of a body of water
IPC: E02B15/10
Filed: 1979-05-15
Abstract: Oil is removed from the surface of a body of water by directing a fluid downwardly on to the surface to force oil to a position below the surface where it is entrained by current flow into a duct. A device for effecting the removal of oil from the surface of water includes a water-powered eductor whose inlet is suspended below the surface of the water from a floating frame; an annular array of nozzles directing water jets downwards to force floating oil towards the inlet; and a conduit whereby an oil-water mixture is conveyed from the outlet side of the eductor. The conduit may carry the oil-water mixture to a gravity separator tank which may be on shore or in a conventional oil tanker floating on the body of the water or to a discharge line which can deliver the oil to a substantial depth below the surface or to a preselected tidal stream. An oil dispersant material may be mixed with the water supplied to the eductor and jets in cases where the oil is to be dispersed in the body of water either at depth or in a tidal stream. The water supplied to the eductor and jets may be recycled from the separator tank and may be heated. <IMAGE>

Patent GB-2063133-A (GB)
Title: A pneumatically operated welding machine control system
IPC: B23K11/31
Filed: 1979-09-06
Abstract: The control system causes the electrodes to approach the workpiece under low pressure until the electrodes have reached a position too close to the workpiece for an operator's finger or hand to be trapped therebetween. This is achieved by having a throttled discharge to the atmosphere during the initial advancing stroke of the electrode actuator. In one embodiment pressure is initially applied to the drive side (12a) of the actuator (11) via pressure reducing valves (23,27) and the delivery line is open to the atmosphere via a high pressure valve (19) muffler; when the electrodes have advanced to a safe position, a limit switch (16) is tripped to energize the high pressure valve (19) which then communicates full welding pressure to the actuator (11). In another embodiment the actuator is caused to move initially by the weight of the electrode and associated equipment and this movement is resisted by a throttled discharge of air from the lower chamber of the actuator, the discharge is controlled by restrictor valves in a circuit which ensures that there is always some pressure resisting movement of the actuator even in the event of leaky seals. <IMAGE>

Title: Single mode fibre
IPC: C03B37/025
Filed: 1980-09-25
Abstract: Single mode optical fibre for operation in the wavelength range 1.5 to 1.7 microns is made by depositing a cladding glass layer (51) and then a core glass layer (52) upon the bore of a silica substrate tube (50).
