The cargo body can be the body of a trailer of a tractor-trailer vehicle or trailer towed behind a vehicle such as a truck. It can comprise a trailer body or other cargo body well-known in the art. A spoiler “flow keeper” mounted to a top surface of the rear of the cargo body, as additional aerodynamic structures or as a standalone spoiler for cargo bodies. The three- or four-sided rear-mounted aerodynamic structure can comprise any of a variety of illustrative embodiments shown and described herein.

A device case closing structure (1) has a shield connector (20) with a work opening (25) and is assembled with a device case (10) while holding terminal fittings (32). A seal cover (40) is assembled with the shield connector (20) for closing the work opening (25). Stud bolts (14) connect the terminal fittings (32) with terminal blocks (13) in the device case (10). The seal cover (40) includes a cover body (41) to be fit to the shield connector (20). The cover body (41) includes a vent hole (55) and a breathable film (57) having waterproofness and breathability is arranged to close the vent hole (55). A part of the vent hole (55) serves as a bolt receiving portion (51) for receiving a tip of the stud bolt (14) inside.

The invention discloses a peeling and cutting machine for sugarcane. The machine comprises a gear ring fixing frame perpendicularly fixed to a bottom plate, a step hole is formed in the center of thedisc surface of the gear ring fixing frame, and a gear ring is arranged in the step hole; the gear ring is an inner gear, a peeling mechanism is arranged on the gear ring, and a transmission disc is also in transmission connection with the peeling mechanism; conveying boxes are arranged on the portions, on the two sides of the disc surface of the gear ring fixing frame, of the bottom plate, a pairof transmission wheels are arranged at the top of each conveying box, and the adjacent sides of each pair of transmission wheels form an annular clamping form to clamp the sugarcane; one transmissionmechanism is arranged in each conveying box, the transmission mechanisms are in driving connection with the transmission wheels, a pair of transmission mechanisms and a motor A form a V-shaped layout, and the motor A rotates to drive the two transmission mechanisms to rotate at the same time. The machine solves the problems in the prior art that the labor intensity of sugarcane peeling is high, the peeling efficiency is low, the peeling quality, the safety and the hygiene cannot be ensured, and manual peeling causes waste.

An elongate capping is arranged to support cross-tensioned or pre-tensioned screening media at a screen deck. The capping includes a pair of arms to grip a carrier beam of the screen deck and a head attached to the arms via a neck. The head includes flexible widthwise extending flanges that are configured to bend and compress towards the arms to support the screening media when mounted on the head under tension.

The invention discloses a defoaming tank and belongs to the technical field of chemical equipment. The defoaming tank comprises an outer tank and an inner tank, wherein a cavity is formed inside the outer tank; the inner tank is at least partially arranged inside the outer tank; a cavity is formed inside the inner tank. The defoaming tank is characterized in that a feeding hole and an outer tank tail gas hole are respectively formed in two sides of the top of the outer tank; at least one gas foam pre-separation weir is arranged inside the cavity of the outer tank; an inner tank tail gas hole is formed in the top of the inner tank; at least one coalescence defoaming plate, a central tube and a liquid blending tube are arranged inside the cavity of the inner tank; a liquid outlet is formed in the bottom of the inner tank.

Disclosed is a novel ternary aliphatic polycarbonate blend derived from carbon dioxide, which is mainly composed of an aliphatic polycarbonate. Also disclosed is a process for producing the ternary aliphatic polycarbonate blend. A methacrylic resin or an aliphatic polyester is incorporated, as a second component, into an aliphatic polycarbonate to produce a blend, and a vinyl resin is added, as a third component, to the blend at a specified ratio, thereby producing a novel ternary aliphatic polycarbonate blend derived from carbon dioxide and having excellent mechanical properties that cannot be achieved by binary blends.

The invention relates to a sealant used for aqueous acrylic acid ester emulsion coating and an application method, the sealant is used for sealing the micropore of an acrylic acid ester film, and the anticorrosion performance of the coating can be enhanced. The aqueous sealant comprises an organic active component, a surfactant and water, the mass ratio of organic active component to surfactant to water is (10-40): (1-3): 100. The organic active component is diglycol (diglycol) or triglycol (triethylene glycol) or a mixture, and the surfactant is polyol ester or polyether or a mixture. A usage method is characterized in that the sealant is prepared by the above ratio, a spraying method or a dipping method is employed for uniformly coating the sealant on an acrylic acid ester moisture membrane surface, and fully filtered in a film aperture. The treated film is solidified for 1-5 hours at the temperature of 80-150 DEG C to obtain the acrylic acid ester coating with good sealing effect.
