Abstract: A pet treat holder includes an outer body shell, treat and actuator openings penetrating therethrough, and an adjustment unit having an internal body situated within the shell, and an actuator joined to the internal body for rotation thereof from outside the shell. The internal body has a non-uniform profile, different areas of which are selectively movable into registration with the treat opening by rotation of the actuator to adjust the effective size of an open passageway through said treat opening. In one mode of use, kibble treats are placed inside the hollow interior space the size of the passageway is adjusted to control an ease by which said kibble treats escape through the passageway. In another mode of use, a chew treat is partially inserted through the treat opening, and wedged into a gripped position between the edge of the treat opening and the adjustment unit by rotation thereof.

Abstract: A rear castor wheel for a tractor includes a beam carried on a fork which connects to a castor mounting assembly attached to a rear pivotal beam of the tractor. A suspension system connects the fork to the mounting assembly to provide suspension movement and includes a first transverse plate assembly attached to the mounting assembly intersected by a second plate assembly attached across the two sides of the fork. The plates are connected by a single elastomeric block located on a first side of the axis remote from the beam and two elastomeric blocks located between the first and second plate assemblies on a side of the axis closer to the beam so that upward movement of the beam causes compression of the first and second elastomeric blocks which are shaped such that the internal strain of the block as the beam moves upwardly is substantially uniform through the block.

Abstract: A public transit vehicle is driven by a hybrid drive system including a diesel engine, a generator driven by the engine, two battery packs for storing energy from the generator and from re-generated braking energy and a transmission in the form of a motor driven by the electrical energy from the generator and/or the batteries. The drive components are mounted on a sub-frame for carrying which is arranged for readily releasable attachment to the main longitudinal beams of the vehicle body so as to be carried on the vehicle body during operation of the vehicle. The sub-frame itself is designed simply and avoiding duplication of support elements so that it is incapable of supporting by itself the radiator and the transmission which are partially supported in use by elements of the vehicle body.
