Abstract: Sample cell devices and support assemblies are disclosed herein. The sample cell includes a novel concentric cylinder and coating design with a right-angle gear drive that enables enhanced rheological measurements in the 1-2 shear plane. The sample call can be used with a support assembly that enables efficient switching between the 2-3, 1-3 shear plane and the 1-2 shear plane without having to remove the sample and allowing for simultaneous imaging with, e.g., SANS or SAXS. Methods for using the sample cell and support assemblies in a 4D-SANS or 4D-SAXS sample environment are also disclosed.

Abstract: A liquid spray device particularly for agricultural and horticultural apparatuses is disclosed. A nozzle is provided through which liquid is emitted in a sheet, preferably a conical sheet. A source of heated air or gas, preferably a burner, is directed to interact with the liquid and is drawn through the liquid curtain to initiate the breakup into droplets of a liquid sheet, thus regulating the droplet size to minimize wastage of expensive agrochemicals or other materials. A shroud is provided to protect the gas in the vicinity of the nozzle from drafts. A thermal sensor is located in the shroud to interrupt the fuel supply to the flame or heated gas if the spray is interrupted.

Abstract: Liquid spray devices are known in which a liquid is emitted from an orifice in the form of a thin sheet of the liquid which subsequently breaks down to form droplets but normally the spray contains very many droplets of very small size which are subject to drifing in cross winds. In this invention means are provided to subject the spray sheet itself to atmospheric environmental conditions such that the sheet breaks down nearer its point of origin and the tendency is for droplets of greater size to be formed with consequent lower tendency to drift. In carrying out the invention hot gases can be released in the environment of the spray sheet and suitable gases can readily be obtained from combusted gases, possibly from the exhaust of the engine of a tractor towing the device.
