Abstract: A tank having a sealing plate and a tank body and lifting mechanism for separating the sealing plate from the tank body of a tank are provided. The lifting mechanism includes a pin inserted into a flange of the tank body extending through the sealing plate, and a threaded device coupled to the sealing plate and selectively contacting the pin to apply a pushing force in response to the threaded device being inserted into the sealing plate.

Abstract: A separator tank and a gas compressor having a separator tank are provided. The separator tank includes a tank body defining an inner volume, a tank inlet pipe providing fluid communication with the inner volume of the tank body, wherein the tank inlet pipe tangentially penetrates the tank body and is oriented to direct fluid entering the tank body in a spiral fluid flow pathway, and a sump tube positioned to collect fluid flowing within the tank body, the sump tube comprising a vertically oriented opening oriented to align and capture fluid flowing along the spiral fluid flow pathway.

Abstract: A lift-off door for an equipment enclosure is provided which comprises tabs on the bottom end of the door that align with slots at the bottom edge of an access window in an equipment housing frame. The tabs extend from a vertical panel on the door through two acute bend angles which are opposite in direction.

Abstract: Pressurized air pick device with variable control that comprises a cylinder and piston assembly for actuating a picking member, and a distribution portion with variable control of the pressurized air to said cylinder and piston assembly, the distribution portion including an upper body, a lower ring and a movable fluid-distribution slider capable of sliding between the body and the ring, characterized in that the distribution portion is housed in the cylinder of the cylinder and piston assembly at the upper portion thereof and coaxially therewith, the variable control for the fluid is housed in the head of the cylinder closing the upper portion of the cylinder connected to a fluid-supply section, and said upper portion of the cylinder includes two channels for conveying pressurized air in tight communication with the distribution portion through the radial channels thereof.
