Abstract: 1,050,898. Protecting fouling of underwater surfaces. DISTILLERS CO. Ltd. Oct 18, 1965 [Dec. 11, 1964], No. 50508/64. Heading E1H. A method of reducing or preventing fouling of underwater surfaces comprises subjecting a stream of anti-fouling liquid dispersed in a gas to conditions which cause sufficient turbulence at places along the stream to redisperse in the gas liquid separating from the stream and distributing the liquid dispersed in the gas against the underwater surface from a plurality of points along the stream. In the method according to the Figs. (not shown) the stream of gas flows along pipe 1 in the direction of the arrow and anti-fouling liquid setting from the stream is drawn along by the stream to a scoop 2 leading to the inlet 7 of a container 5 surrounding a trap 4 open ended at one end, 9, and containing a perforation 3 in the pipe wall at the other, the trap and container forming a dispersing device which produces sufficient turbulence to cause the settled liquid to redisperse in the gas and pass out of the perforation 3, excess liquid dispersed in the gas escaping from an outlet orifice 8 in the container 5 of the dispersing device.

A drawing device, in the nature of a toy, comprises a frame, power means for moving the frame over a drawing surface, interrupting means associated with the power means to cause the direction of movement of the device over the surface to change intermittently, and marking means on the frame the pattern of movement of which is drawn on the surface. As shown, the device has the form of a mechanical man comprising a head part 12, Fig. 1, a body 14 and arms 16, the arms 16 having sleeve parts 18, 18a to receive a pen or pencil 20. Other pen receiving bosses 24 may be provided on the body part 14. The device is supported on the drawing surface 22 by two wheels 34 at the sides of the front of the device and by a member 39, Fig. 4 (not shown), depending from the rear. A motor 30 working off dry batteries 32 drives the shaft 36 of the wheels 34 through a reduction gear 38. Another shaft 52 is also driven through the gear 38 and carries a replaceable cam 50 having raised and lowered parts, Fig. 1. The cam 50 co-operates with a follower 48 on a member 42 situated adjacent to one of the wheels 34 and pivoted at 44, Fig. 5, to the frame. A depending foot 46 on the member 42 rests on the surface 22. When a raised part of the cam 50 engages the follower 48, the foot 46 is moved downwardly relatively to the frame to raise the adjacent wheel 34 from the surface, so that the device is caused to rotate about the foot 46 by the drive of the other wheel 34 so that one or more patterns are marked on the surface by the pen or pens 20. The pattern may be changed by sliding the cam 50 axially off the shaft 52 and inserting a different cam.
