Abstract: A light weight wheel structure having a hub member of substantially an elongated configuration of constant cross section defining a plurality of openings therethrough, and including a pair of end plates which are held in recessed areas at opposite ends of the hub member by way of a plurality of fasteners extending through the plurality of openings in the hub member. The hub member is of a form capable of being formed of material, such as aluminum, by an extrusion process, whereby a continuous outer cylindrical surface is provided for the mounting of a tire formed of elastomeric material.

Abstract: An installation system for mounting outdoor lighting wherein there is provided a foundation member in the form of a mildly compressible pipe member which is mounted in the ground, and an adapter which may form an electrical connection box. A light standard can be mounted on the adapter which has a lower portion, at least a portion of the outer surface of the lower section being in the form of a section of a sphere for close reception in an open upper end of the pipe member. The adapter within the pipe member provides adjustment movement in a ball and socket fashion so that regardless of whether the pipe member is not accurately installed in the ground, the adapter can be moved to achieve vertical orientation of the light standard prior to clamping of the pipe member to prevent further relative movement between the standard and its foundation member.

Abstract: An apparatus and method for preparing sites for planting tree seedlings, and more particularly establishing mounds on the ground surface formed of soil scooped from the ground. The apparatus may be of the pull type having a pair of scoops and scoop operators for moving the scoop through a ground penetrating and mound depositing cycle. A control times the cycling of the operations so that the mounds formed during a constant movement in the forward direction are arranged in two lines and wherein the mounds in the two lines may be in a staggered relationship. The apparatus has rear wheels and a front towbar. Actuators are provided for moving the wheels up or down relating to the frame and also moving the towbar so that the height, as well as the fore and aft tilt, of the frame relative to the ground can be varied to control the depth of penetration of the scoops. The wheels also have actuators which allows adjustment of the tread of the wheels.

Abstract: A sprocket wheel for a tracked vehicle, the sprocket wheel being in the form of an annular body having teeth integrally moulded of elastomeric material, the teeth including metal inserts moulded therein and providing track engaging surfaces in the inter-tooth valleys about the sprocket wheel.
