Abstract: The method and apparatus for forming an encapsulation or encasement about a structural member that is particularly well suited for use in a marine environment is disclosed. A two component polymer system for protective and repair encapsulation is pumpable in two separate streams to the location of the structural member to be encapsulated. The two reactive components are combined in a static mixer immediately prior to being injected within the surrounding translucent jacket. By combining the reactive components immediately prior to use, premature set up is avoided and the resulting grout may be directed to flow upwardly in the jacket for enhancing final properties. By suitable coloring of the components, visual monitoring of the final mixing and distribution in the translucent form or jacket of the encapsulation material may be monitored. A field test for determining bond strength of the encapsulation polymer to the structural member is also disclosed.

Abstract: A method and apparatus for pitting olives and then slicing the pitted olives. In a preferred embodiment, each olive is carried in a cup positioned between a coring knife and a pitting knife in a manner so that the longitudinal axes of the cup and the knives coincide. As the cup and knives rotate around a drive shaft along parallel circular paths, a system of cams extends and retracts the knives relative to the cup, in order to pit the olive. After the pitting operation, the cup (containing a pitted olive) continues to rotate along its circular path past a set of slicing knives. The slicing knives are oriented substantially parallel to the plane of the cup's circular path, so that the slicing knives act as wedges to sever the olive cleanly into slices as the cup translates past the slicing knives. In the inventive method and apparatus, both the pitting and slicing operations are performed on each olive while the olive is held in a known orientation.

Abstract: A textured, contoured toilet anti-splash and silencer device for adjustable mounting on a toilet at the rear, or the front, of the bowl. The device, a contoured, textured maze, disperses urine into the water of the toilet bowl by breaking, without splash, the velocity of the urine stream, containing the urine within the contour, and then directionally draining the urine noiselessly into the water of the toilet. Depending solely upon the needs of the user the maze device can be suspended within the bowl on either adjustable mounts at the back of the toilet or on fixed mounts at the front of the toilet bowl, thereby ensuring that it is able to be positioned out of the way when the seat is lowered. The device is preferably made of molded plastics to ensure contours and for corrosion resistance. A flange on the device induces self-cleaning during toilet flushing in order to keep the device hygienically clean and odor free.
