According to one embodiment, a cleaner head (2) includes a first rotor (15), a second rotor (16A,16B), and a contact surface (36A, 36B). The first rotor (15) can be rotationally driven in a state where an outer peripheral surface (21) of the first rotor (15) is in contact with a sheet (53) that includes organic fiber and is formed on a base (52), and can remove a part of the sheet (53) from the base (52). The second rotor (16A, 16B) is arranged next to the first rotor (15) in a direction along a rotation axis (R) of the first rotor (15), and is rotated together with the first rotor (15) in a state where the second rotor (16A,16B) is not in contact with the sheet (53). The contact surface (36A,36B) is in contact with an outer peripheral surface (22A,22B) of the second rotor (16A,16B) at a position away from the sheet (53) around the rotation axis (R).

A container rinsing system has a nozzle adapted to be positioned proximate an opening of the container and adapted to direct a supply of air in any orientation to the container. A vacuum member is positioned around the air nozzle and adapted to vacuum foreign particles away from the container. A system comprises an air source and a manifold having a manifold inlet, an ionization unit, and a plurality of manifold outlets along with a plurality of air nozzles. Each nozzle has a nozzle inlet, a nozzle outlet, and a nozzle passageway extending between the nozzle inlet and the nozzle outlet. The ionization unit is placed within the manifold, and the plurality of nozzles are located on the plurality of manifold outlets such that during operation air is ionized before entering the nozzles. The ionized air is used to clean containers.

This invention concerns an arrangement 1 intended to be used in a ventilation arrangement in order to hold and control an air channel 2. The arrangement 1 comprises a single arm construction 1.1 that is arranged along the outer surface 2A of the air channel. The arm construction 1.1 comprises two arm sections 3 and 4 arranged one after the other, a first joint 5 that unites a first arm part 3 with a fixture arrangement 6 that holds and maintains the basic position of the arm construction 1.1 and that makes possible different positioning, bending and stretching, of the arm construction 1.1 and the air channel 2, a second joint 7 that unites the first arm section 3 with the second arm section 4 and that makes possible different positioning, bending and stretching, of the arm construction 1.1 and the air channel 2. Each arm section 3 and 4 comprises an extended aluminum profile 8 and 9. The invention concerns also a ventilation arrangement comprising such an arrangement 1.

The invention relates to a prevention means characterised in that it is a collection and retention means for receiving fine and/or ultrafine particles at the source of emission of the fine and/or ultrafine particles, said collection and retention device being designed for a single or specific use for specific and localised standardisation, repair or maintenance work.
摘要:
The tilting device includes a driving mechanism and a power transmission mechanism. The driving mechanism includes a driving device including a drive shaft and a first engaging member. The drive shaft rotates around a first axis. The first engaging member is disposed on the first axis to rotate integrally with the drive shaft. The power transmission mechanism includes a second engaging member, a propeller shaft, a piston, and a reduction gear. The second engaging member is disposed on the first axis engageable with/disengageable from the first engaging member. The propeller shaft is disposed on the first axis. The propeller shaft is rotatable integrally with the second engaging member around the first axis. The piston reciprocates the second engaging member between a first position and a second position along a direction of the first axis. The reduction gear is joined to the other end side of the propeller shaft to decelerate the rotation of the propeller shaft. The reduction gear causes an output shaft joined to an object to rotate around a second axis.
摘要:
[Problem] Due to the low suction strength or an unsuitable positional relationship or distance between the suction feed and the oral cavity, conventional extra-oral intake devices exhibit the problem of not being able to fully suck particulate matter and droplets from teeth, shavings from repair products, saliva, bacteria, blood, rinse water, tooth surface cleaning agents, etc., that are dispersed to outside the oral cavity during practice. [Solution] In order to improve suction strength, the present invention provides an intake device that is equipped with a protruding airflow-regulating member, the top of which is oriented in the direction in which the fluid flows into the opening part of the suction feed, and that can efficiently suck dispersed particulate matter and droplets within a wide range.
