Abstract: A propellant-free composition for lustering and protecting a surface such as a rubber sidewall of a vehicle tire or a vinyl or similar surface. The composition has (1) from about 10 wt. % to 100 wt. % of a high molecular weight liquid linear polysiloxane having a molecular weight above about 550, and (2) from 0 wt. % to about 90 wt. % of a low molecular weight liquid linear and/or cyclic polysiloxane having a molecular weight below about 550. Surface activity of the silicone component of the composition is such that the high molecular weight polysiloxane functions to produce a high luster, while the low molecular weight polysiloxane functions as an evaporative carrier-solvent diluent medium for delivery of the silicone component to the surface and to produce an even distribution on that surface.

Abstract: A composition for lustering and protecting a surface such as a rubber sidewall of a vehicle tire or a vinyl or similar surface. The composition has as one ingredient thereof from about 5 wt. % to about 95 wt. % of a silicone component. This silicone component has (1) from about 10 wt. % to 100 wt. % of a high molecular weight liquid linear polysiloxane having a molecular weight above about 550, and (2) from 0 wt. % to about 90 wt. % of a low molecular weight liquid linear and/or cyclic polysiloxane having a molecular weight below about 550. The composition includes a second ingredient being from about 5 wt. % to about 95 wt. % of a propellant component, and contains no petroleum distillate solvents.

Abstract: A large screen display apparatus comprising a display unit composed of a plurality of modules and a housing accommodating the display unit. Each of the modules includes a plurality of units arranged in a matrix form, a power source and a control unit. Further, each of the units includes a plurality of light emitting elements arranged in a matrix form and a drive circuit for the light emitting elements. Due to this arrangement, it is possible to provide a large screen display apparatus being economical, small in weight and volume and high in usability.
