Abstract: An infeed conveyor is provided with high pivot capability. High pivot capability is the capability to raise the elevation of at least one end of an infeed conveyor belt to an elevation higher than regular horizontal operation if the belt placer is operating lower than the surrounding grade. High pivot capability prevents the infeed conveyor from bottoming out on the grade of the haul road or adjacent pavement; and in some instances, high pivot capability allows use of the belt placer under conditions that belt placers without high pivot capability could not operate. Also disclosed is the ability for belt placers to be used to pave in both forward and reverse directions, whereas former belt placers could only pave in the forward direction. This is accomplished by the ability to rotate the discharge conveyor under one side of the belt placer, and changing the direction in which the belt placer travels.

Abstract: A tennis ball retrieving apparatus comprises a wheeled vehicle having a front end and a rear end. The vehicle has a ball storage container disposed at a level enabling ready removal of balls therefrom by a person next to the vehicle while the person is in a standing position. There are a pair of horizontal ball gathering arms at the front of the vehicle arranged in V formation to provide an apex portion to which gathered balls are fed. A pair of the wheels of the wheeled vehicle are in traction contact with the surface on which the vehicle is supported to be driven thereby in rotary fashion as the vehicle is moved over the supporting surface. The wheels are supported with the lower portions of the tires spaced from one another less than the diameter of a tennis ball so as to grip the same when a ball is fed thereto. A chute extends from the area just rearwardly of the lower portions of the tires upwardly to the storage container.

Abstract: An exercise machine having a frame supporting a seat in an off-the-floor position. A pair of arm levers are mounted on the frame and provide resistance to movement in two directions, with the resistance to pushing from rest positions being less than the resistance to pulling to return the arms to the rest positions. The machine has a pair of leg levers wherein resistance to movement in a pushing direction is greater than in a pulling direction. The resistance to movement of the exercising levers is provided by friction mechanisms and springs, with the frictional force being greater than the spring force. The friction mechanisms offer the same resistance in either direction of movement, but the springs aid movement of the arm levers in push, when returning them to rest positions, while aiding the foot levers in a pulling direction. The arm levers have grips rearwardly inclined from the main portions thereof for better in-line application of force by the user.
