Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user's hand(s) in connection with an operation of the door handle to sanitize the user's hand(s).

The present disclosure provides a nozzle assembly including a unitary nozzle body having multiple flow channels therein. Spray nozzles are mounted to outlet ports of the flow channels, such as via a snap-fit connection. The spray nozzles can be keyed with the outlet ports to align them in a predetermined position and lock the spray nozzles and the nozzle body together radially. Vehicles and systems incorporating a nozzle assembly are also provided.

A sensor-cleaning apparatus includes an upper piece, a lower piece fixed to the upper piece, a plurality of inserts inserted into the upper piece, and a plurality of nozzles. The upper piece and the lower piece form a tubular segment that is elongated along an arc of a circle and encloses a chamber. Each nozzle is formed of the upper piece and one of the inserts. Each nozzle includes a deflection surface and a tunnel from the chamber to the deflection surface, and each tunnel is partially formed of the upper piece and partially formed of the respective insert.

The rotor of the invention has two legs fastened to a rotary base, wherein the legs are provided with asymmetrically arranged boreholes facing upwards and boreholes facing downwards, wherein the boreholes facing upwards have the shape of an ellipse, while the boreholes facing downwards have a circular shape. The boreholes facing upwards and the boreholes facing downwards are formed, such that the jets from the boreholes facing upwards act vertically upwards and the jets from the boreholes facing downwards act vertically downwards, i.e., in a direction 90° with respect to the axis of the legs.

A travelling agricultural irrigation installation is provided having multiple generally horizontal irrigation sprinklers each being a length of pipe closed at each end and having multiple outlet orifice sets along the length thereof. Each orifice is in the form of a hole through the pipe wall having an orifice diameter selected to provide, in use, a jet of water that breaks up into droplets. Each orifice set comprises multiple orifices having axes extending in different angular directions relative to the pipe axis to provide a generally rectangular spray pattern. The length of each sprinkler pipe or the number of orifice sets is dependent on the speed at which the sprinkler is to move over the ground. Typically the installation is a centre pivot installation; the sprinkler pipes are all connected to a common radial main supply pipe; and the water delivery increases with increased distance from the centre pivot.

A nozzle assembly, an evaporation plating apparatus, and a method of manufacturing an organic light emitting diode device is provided. A first heating element is arranged in the hollow cavity in the sidewall of the nozzle. When organic material is vapor deposited, the first heating element can perform heating to raise the temperature of the peripheral wall of the nozzle to be substantially the same as or slightly higher than the temperature of the evaporation plating chamber, thereby maintaining the temperature in the nozzle within a suitable range so that it is neither too low to cause the organic material to condense in the nozzle nor too high to carbonize the organic material.
