Abstract: Disclosed are growth media that can be applied to soil surfaces and utilized to protect, feed, and encourage growth and development of plants, such as grass. Growth media can include a hygroscopic particulate material as well as a hygroscopic fibrous component. Media can include an adhesive as may be used to bind fibers to one another and encourage stability of the medium following application to a ground surface. Growth media can include additional materials such as seeds, fertilizers, pesticides, soil conditioners, and the like. Growth media can be completely organic and can retain moisture and structure so as to provide long term protection and nutrient deliver to developing plants.

Abstract: A two stage toilet tank bowl control system includes a tank ball selectively positioned on the valve seat in the water tank. The tank ball is linked to a lifting lever so as to raise the tank ball from the seat when the lifting lever is rotated in its flushing direction. An air outlet tube communicates with the interior of the tank ball to permit air to be exhausted from the interior of the tank ball. The air tube communicates with a passageway in a air flow block mounted to the wall of the water tank. The passageway has a full flush branch and a partial flush branch. A partial flush valve maintains the partial flush branch closed during conditions of full flush. A full flush handle moves the lifting lever in its flushing direction with the partial flush valve maintained in a closing condition against the outlet of the partial flush branch.

Abstract: Disclosed is a process for forming images which comprises (a) generating an electrostatic latent image; (b) contacting the latent image with a developer comprising a colorant and a substantial amount of a vehicle with a melting point of at least about 25° C., said developer having a melting point of at least about 25° C., said contact occurring while the developer is maintained at a temperature at or above its melting point, said developer having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 108 ohm-cm at the temperature maintained while the developer is in contact with the latent image; and (c) cooling the developed image to a temperature below its melting point subsequent to development. Specific processes disclosed include electrophoretic development processes, polarizable liquid development processes, and photoelectrophoretic development processes. Optionally, the developed image is transferred to a substrate subsequent to development.
