The invention is low-noise, low-pressure torpedo launching system having cially designed ports connecting a water cylinder to an impulse tank and to a method for designing such ports. The invention uses specially designed C-shaped water cylinder discharge ports to provide a continuous and minimized pressure gradient as the ports are closed by the water piston. The resulting controlled deceleration of the water piston reduces operational noise, reduces mechanical stresses and eliminates the need for auxiliary dashpot components.

Apparatus and method for designing a specially ported torpedo launching

A device for applying a film of liquid adhesive to the inside lip surface a cylindrical cap includes a vessel containing a body of liquid adhesive, a means, e.g., a drive plate, for rotating the cylindrical cap and one or more rotatable knurled wheels or discs which touch the liquid adhesive and resiliently contact the inside cap surface, whereby the wheel is rotated by rotation of the cap and applies the adhesive to the cap. Magnets in the drive plate attract magnets in the knurled wheels sufficient to constantly turn the wheels when they are not being resiliently pressed against the inner surface of the cap.
