An adjustable inlet assembly for a separator includes a nozzle positioned in an inlet of a cyclone housing, an inlet housing coupled to the cyclone housing and sealing therewith around the inlet, and a movable rod disposed at least partially in the inlet housing. The movable rod is configured to move between a first position in which the movable rod at least partially obstructs fluid flow in the nozzle, and a second position in which the movable rod does not obstruct fluid flow in the nozzle.

A device collects material from air. The device swirls air within a fluid housing so as to deposit the material, such as viruses, bacteria, fungi and other particles, from the air in a way that the material can later be analyzed. The device can be used to provide for detection of airborne organisms or properties of material in the air.

A separation apparatus for separating hydrocarbons and water, comprising a vessel (1) and an insert (5, 6) within said vessel (1). The has a bottom (7), a conical wall (8) and a quiecer (10) at the top of the wall (8), which enclose a separation chamber (11). The insert (5, 6) has an inlet pipe (12) for a mixture of water and hydrocarbons and a spreader arrangement (13, 14) arranged inside the separation chamber (11), which directs an inflow of fluids in a tangential direction, setting the fluids into a tangential laminar swirl. The vessel (1) has at least one manhole (3, 4), and said insert bottom (7), wall (8) and quiecer (10) are assembled by a plurality of generally wedge shaped segments (7a-l, 8a-l, 10a-l) having a size that allows the segments (7a-l, 8a-l, 10a-l) to be brought through the manhole (3, 4).

A method and washer head assembly for washing a surface of a solar panel, includes lowering a washer head frame onto a solar panel. The washer head frame includes a washer frame cross member having a swivel mounted thereon. The swivel is mounted below a center of gravity. The frame includes a upper frame rail and a lower frame rail. A plurality of lath brushes together extend, generally, the length of the washer head frame. The lath brushes are made up to include a plurality of bristles being of sufficient number to support the washer head frame against the surface of the solar panel without damage to the solar panel. The lightness of the frame and the resilience of the brush bristles assure that the washer head frame will not come into damaging contact with the solar panel.

An oil separator of an outdoor unit of an air conditioner includes a tank body, an inlet pipe, a gas outlet pipe and a separating member, the lower end of the tank body being provided with an oil outlet, the inlet pipe being connected to the tank body, the central line of the inlet pipe being parallel to a horizontal direction, the gas outlet pipe being connected to the upper end of the tank body. A mixture has a tangential speed and rotates in the tank body, and oil-gas separation is realized by a centrifugal force, and kinetic energy loss is reduced. The inlet pipe is parallel to the horizontal direction so as to reduce unnecessary collisions between the mixture and the upper end of the tank body, and to allow sufficient time for the mixture to be separated.
