An apparatus for supplying chemical liquid may include a chemical liquid supply head, a receiving member, a removing member and a supplying member. The chemical liquid supply head may provide a chemical liquid onto a substrate. The receiving member may receive a recycle chemical liquid discharged from the chemical liquid supply head, and the removing member may remove impurities remaining in the recycle chemical liquid received in the receiving member. The supplying member may provide the recycle chemical liquid from which the impurities are removed to the chemical liquid supply head.

Described herein is a sidewall suitable for use in a metallurgical furnace, and metallurgical furnace having the same. The sidewall has an upper wall, an outer wall coupled to an outer side of the upper wall, and extending downward from the outer wall. A sloped wall is coupled to an inner side of the upper wall. The sloped wall extends downward and inward from the upper wall. The sloped wall has a first surface facing the outer wall and a second surface facing a centerline of the sidewall. A spray cooling assembly is disposed between the sloped wall and the outer wall. The spray cooling assembly is configured to spray coolant on the first surface of the sloped wall.

A product system for an agricultural sprayer includes a product tank configured to store an agricultural product. A reclaim system can be configured to provide the agricultural product within a flow assembly to a product tank. A computing system can be communicatively coupled to the reclaim system. The computing system can be configured to receive information indicative of one or more characteristics of the agricultural product inputted into the fill station during a fill mode; detect termination of the fill mode; and activate a reclaim mode to move the agricultural product from the flow assembly to the product tank through activation of the reclaim system, wherein one or more operating conditions of the reclaim mode are based on the one or more characteristics of the agricultural product.

An agricultural method for preventing roll-back of an agricultural vehicle may include receiving a roll-back prevention input from a speed setting device indicative of a command to increase the transmission speed of the hydrostatic transmission while a service brake of the agricultural vehicle is engaged. Further, the method may include adjusting a speed mapping for the speed setting device from a predetermined speed mapping to a roll-back speed mapping in response to the roll-back prevention input, with the roll-back speed mapping being associated with a reduced speed range. Additionally, the method may include determining a transmission control command associated with a current position of the speed setting device based on the roll-back speed mapping and controlling an operation of the hydrostatic transmission to adjust the transmission speed based at least in part on the transmission control command.

The invention relates to a device including a nanoaerosol nozzle for releasing an aerosol with very fine particles.

A liquid discharge apparatus includes a liquid discharge head that discharges a liquid from multiple nozzle holes to apply the liquid to an object and circuitry that causes the liquid discharge head to discharge the liquid from a first number of the multiple nozzle holes to a first area at a start of an application of the liquid to the object as a first discharge, discharge a first total amount of the liquid to a receptacle different from the object before the first discharge as a first dummy discharge, discharge the liquid from a second number of the multiple nozzle holes to a second area at the start of the application as a second discharge, discharge a second total amount of the liquid larger than the first total amount to the receptacle before the second discharge as a second dummy discharge. The second number is larger than the first number.

An essential oil reflux-type atomizer comprising the following structures: chassis (10), housing (30), atomization chamber (310), gas pump (21), gas tube (22), gas nozzle (23), oil nozzle (24), filter atomization mechanism (40). The filter atomization mechanism (40) is installed in the housing (30) and has a plurality of filter housings (41). A lower end of each of the filter housings (40) has one or more through holes (411). When the gas nozzle (23) ejects an airflow, the airflow draws out the essential oil through the oil nozzle (24) to form a mixed airflow which passes through each of the filter housings (41) successively. Larger essential oil droplets in the airflow are filtered by each of the filter housings (41) to be recycled, while the atomized essential oil gas will pass through the through holes (411) of each of the filter housings to be dispensed. At the same time, the essential oil droplets in the through holes (411) are re-atomized by the airflow to improve the atomization performance. The atomization chamber (310) comprises a guide board guiding the airflow from the gas nozzle (23) upwards towards the filter atomization mechanism (40).
