Abstract: A method for video image color shading and recreation uses already compressed video data so that another video compression scheme is not further needed to compress the final shaded or recreated image to fit a specific storage medium.

Abstract: An aperture covering including track-guided interconnectable panels that are compactly stored in a storage area containing weight counterbalancing mechanisms, such as a compressed spring, is described. When the panels are stacked in the storage area and removed one at a time, the first panel is removed from the storage area and enters the track. As the first panel moves through the track, it interlocks with the second panel and forces the second panel out of the storage area and into the track. Interlocking and removal of the panels continues until all of the panels are removed or the first panel reaches the end of the track. Weight counterbalancing can be assisted by track-contained toothed belts, cable and ball drive mechanisms, or other counterbalancing methods. The resulting aperture covering requires minimal storage space for the open aperture position, minimizes exposure to potentially hazardous counterbalancing mechanisms, and allows for heavy-weight panel construction.

Abstract: Infestation of cockroaches in buildings and houses are treated and effectively eliminated by determining the location of the eggs or the young, immature insects and treating them with a suitable insecticide before the insects emerge and begin to migrate to other areas. The treatment can also be applied to mature roaches in these areas before they lay their eggs. Frequently the places where the young roaches develop or hatch is in the foundations and walls of buildings and under concrete slabs where sewer or water lines occur and other damp or humid areas. A particularly effective insecticide has been found to be a dilute solution of O, O-diethyl-O- (2-isopropyl-6- methyl-4 pyrimidinyl phosphorothioate which is used to saturate the area being treated.
