Abstract: A device for suspending a mower cutting deck that includes a retention member connected with the frame of a vehicle. The retention member receives a linkage bridging the cutting deck and the frame. To receive this linkage, the retention member includes a channel having a top end through which the linkage is inserted and a bottom end in which the linkage seats when the deck and the frame are connected. A throat portion is provided between the top and bottom ends.

Abstract: A hybrid rocket motor is provided with a precombustion chamber supplied with propellant from separate fuel and oxidizer sources. The propellant can be in the form of gas or liquid and injected substantially tangentially into the head end of the hybrid motor adjacent the oxidizer injector to form a propellant swirl. As the hybrid motor oxidizer is injected into the swirl, it is heated and gasified, and assumes a swirling motion which increases the oxidizer path length and thereby increases the dwell time of the oxidizer. The increased dwell time increases combustion efficiency and permits multiple restarts of the hybrid motor. The propellant may also be a combination of solid and fluid reactants. In one embodiment, the oxidizer injector is extended into the combustion chamber to form a toroidal precombustion chamber which has an annular nozzle adjacent a face of the oxidizer injector.

In this way, temperature rise of the front three-way catalyst (8) is suppressed, and the temperature of the rear three-way catalyst (9) rises.

Abstract: In a microactuator having substantially parallel beams, the free ends of the beams are detached from the substrate and rigidly interconnected with one another. Differential thermal expansion of the beams causes deflection of the free ends as a unit laterally away from the thermally expanded beam. Depending on the choice of thermally expanded beam, the deflection can be either in or out of the plane parallel to the substrate. Selective heating is achieved for example by passing electric current through a pair of beams in series. Each beam has an independent electrical contact pad at the base end, and all beams are connected together electrically at the free end. A voltage is applied across the selected beam pads, whereas the non-selected beam pads are disconnected. Multiple microactuators can be combined cooperatively, e.g., to move a stage in a plurality of directions.
