Abstract: The present invention is a portable two-way awning for use with recreational type trailer vehicles. The awning is comprised of a number of roof panels made with two sheets of aluminum surrounding a polystrene core. A hanger mechanism is bonded to each of the panels, and suspends them on an adapter rail that slidingly engages with a standard awning attachment rail. The roof panels mate together via a number of interlocking members disposed on theirmating sides. The outer periphery of the roof assembly is surrounded with a number of extrusion members. Once the roof assembly is pivoted to a nearly horizontal position, it is supported at its front end by a number of adjustable height poles, two of which swing freely into n vertical position when the roof is initially erected. The awning requires no tools or caulking to set-up, and takesless than thirty minutes to either erect or dismantle. The awning is relatively light in weight, yet strong enough to withstand the harshest of weather conditions.

Abstract: The invention is a method of ordering plant embryos so that a specified end of the embryo is always oriented in a predetermined direction. The embryos are preferably first fairly rapidly descciated to about 15 % moisture content. They are then suspended in a benign liquid flotation medium having a density in the range of about 1.059-1.104 g/cm3. The density must be adjusted empirically so that a predominant number of viable embryos will float and nonviable embryos will sink. In at least the case of conifer somatic embryos, they will float with the end bearing the latent cotyledons upward.  After sufficient separation time in the flotation medium the oriented embryos are swept by a flowing liquid stream into a conduit. They enter cotyledon end first and are then carried to a delivery point without losing that orientation. Here they are separated from the transporting medium. The embryos, still positioned cotyledon end first, may then be picked up by robotic or other means for further processing, such as insertion into an artificial seed.
