A device is described for protecting a sensor window. The device includes a two-piece nozzle system and is configured for generating a first and a second fluid flow, a first piece of the two-piece nozzle system being fixedly situated with respect to the sensor window, and a second piece of the two-piece nozzle system being configured for assuming different positions with respect to the first piece of the two-piece nozzle system, and the two-piece nozzle system being aligned with respect to the sensor window to direct a predominant portion of the first fluid flow in parallel to the sensor window and to direct a predominant portion of the second fluid flow in the direction onto the sensor window.

A method of improving the performance of a powder dusting tip delivering powdered diatomaceous earth powder minimizing clogging in powder bulb duster tips through the use of tips with a more free flowing configuration and different spray patterns than the standard tip assembly and a flexible one piece powder dusting tube, which is attached to the tips which connects to reservoir of powder type insect repellents such as diatomaceous earth pesticides, boric acid pesticides, sevin based insecticides, deltamethrin based insecticides, and permethrin based insecticides as well as other powdered insecticides through threaded connections, made from flexible rubber tubing supported by memory wire that allows the powder duster tip to be positioned for hard to reach areas.

The invention relates to nozzle tips including a nozzle body and a tip portion, configured to minimize the accumulation of a resin on the nozzle tip as it is dispensed through the nozzle tip. The nozzle tip can contain a central flow channel and an internal portion that branches and guides the resin into multiple exiting flow channels that define tangential pathways to the outer surface of the nozzle tip. The nozzle tip can include grooves that define extended, sharply angled flow paths for the resin. Nozzle tips can have a neck portion separating a nozzle body and a tip end of the nozzle tip; here, a doughnut-shaped space located around the neck portion can be defined by the base of the nozzle, the crown of the nozzle, and the neck portion, for encouraging turbulent flow of the resin to scour the nozzle tip during dispensing.

Rapid cooling section of a continuous metal strip treatment line, where the strip is cooled with a spray of liquid or a mixture of gas and liquid using nozzles located on each side of the strip. Along the direction of movement of the strip, it includes at least one row of flat spray nozzles across the strip followed by at least one row of cone spray nozzles across the strip.

A fire protection system is provided for a space having a pitched roof constructed of structural members extending from a ridgeline to an eave, with respective channels therebetween. A first row of sprinklers is mounted to a first branch line extending generally parallel to the ridgeline. Each sprinkler is positioned within a respective channel, with consecutive sprinklers spaced apart having no less than one, and no more than five, channels therebetween. A second row of sprinklers, downslope from the first row, is mounted to a second branch line extending generally parallel to the first branch line. Each sprinkler thereof is positioned within a respective channel, with consecutive second row sprinklers spaced apart as in the first row. Each second row sprinkler is also placed within a different channel from each first row sprinkler. A farthest number of channels between a first row sprinkler and a second row sprinkler is three.

In accordance with embodiments of the invention, a portable face rinsing faucet attachment is provided. The portable face rinsing faucet attachment includes a body. An intake channel is operable for attachment to a faucet to receive pressurized water from the faucet. A flow path is defined by the body and is in fluid communication with the intake channel. The flow path is operable to receive pressurized water from the intake channel. A plurality of spray channels is defined by the body and are operable to receive and pressurize water from the flow path. A plurality of spray holes is defined by the spray channels and are operable to receive and spray water from said spray channels. A drain is defined by the body.
