Abstract: The invention relates to a parallel spacing guide that when attached to a hand-held marking device (spray gun), it enables the user to mark an accurate and consistent extended line one to four feet from a curb, wall, or other vertical surface; and one to four feet from a line or score mark along the ground in cases where a vertical surface is temporarily absent. This is achieved by having the parallel spacing guide soundly attached to a hand-held marking device. While holding the parallel spacing guide in one hand by the embodied handle and the attached marking device by it's handle in the other hand, the user pushes the invention along the street or highway with the end of the parallel spacing guide butted against the curb or wall while simultaneously using the marking device to mark the line by discharging paint or chalk.

Abstract: The invention relates to creating an optical illusion of fluid or water in a display device which shows a solid water stream with undulations that rises, levitates or falls slowly. The illusion can be viewed under certain circumstances in ordinary room lighting. Also, the solid water stream with undulations can simultaneously transform into a set of rising, levitating or falling water droplets. The entire illusion may be examined and even touched by the audience.

Abstract: A bicycle cushion seat cover with aerodynamic shaped bag is described which provides comfort and support to the bicyclist without chaffing and bruising. The bicycle cushion seat cover with aerodynamic shaped bag weighs less than 9 ounces and is composed of a foam with a density of 1.8 to 2.8 lbs. per cubic foot and an impression force deflection of between 75 and 95, a vinyl cover having a density of 2 ounces per square foot, 2 underside flaps and an underside lining with a density of 2 ounces per square yard which provides firm attachment means, and an aerodynamic shaped bag with maximum dimensions less than those of the maximum back dimensions of the bicycle cushion seat cover such that the bag creates minimal aerodynamic drag.

Abstract: The invention relates to creating the illusion in a beverage dispensing device of liquid droplets that fill a drinking glass despite their appearance of rising from the drinking glass. The illusion is accomplished by oscillating the liquid and then applying a flashing light source whose frequency is slightly greater than the liquid oscillations. The enclosure and curtains of the invention allow the illusion to be viewed under certain conditions in room lighting. Also, under certain conditions an optical surface is attached to the enclosure which visually masks the ambient light.
