Abstract: An aerosol throat spray with a spray-counting mechanism including a lead screw driven in rotation by a rachet in which a follower on the lead screw moves from a starting location indicating the aerosol is "full" to an ending position indicating the aerosol is "empty", wherein the rachet is actuated by a pawl of springy construction material which, after each power stroke, returns to a ready position for the next power stroke in response to the spring urgency of its construction material.

Abstract: An improved tool tray support assembly comprises a center section, opposed extensible lateral support members and end support assemblies. The end support assemblies fit onto end sections of the lateral support members, and support the assembly on opposed edges of an engine compartment of a motor vehicle. The lateral support members slide within the center section and can be locked at any desired position to adjust the spacing of the end supports to accommodate various engine compartments. The angular orientation of the center section can be varied by adjustment of the position of the lateral support members with respect to the end supports. Tool trays of standard dimensions fit between the opposed lateral rails of the support member to enable convenient storage of small tools and parts. The tool tray assembly may also be supported beneath a vehicle service lift or the like, and the tool trays may be supported by brackets on wheeled stools for increased flexibility in their use.

Abstract: A toy vehicle comprises a chassis having a pair of rear wheels journaled for rotation about a rigid axle and a pair of front wheels mounted for being steered cooperatively. A steering mechanism is controlled by a steering wheel at the end of a steering column connected to the steering mechanism by a universal joint. A child playing with the vehicle can propel the vehicle forward by pushing on the steering wheel, but can only steer it in a desired direction of travel by turning the steering wheel.

Abstract: A spherical vehicle including a spherical shell having a drive shaft secured to the interior wall thereof. A drive motor is connected to the shaft for imparting a rolling motion to the spherical vehicle on a supporting surface. Continuous steering of the vehicle is accomplished by changing the position of a mass suspended from the drive shaft to thereby change the center of gravity of the vehicle.
