Abstract: Aspects herein are directed to a washable and reusable face mask that provides effective filtration of small-sized particulate matter while providing a large surface area for gas exchange. The face mask is formed from knit materials and polyurethane materials and includes a plurality of molded pleats that extend from a right side edge to a left side edge of the face mask.

Abstract: Some examples described herein include a flexible hopper for a conveyor system. The flexible hopper may include a hopper weldment attached to a frame of the conveyor, wherein the hopper weldment surrounds a charge end of the conveyor, a flexible frame configured to enable an opening of the flexible hopper to expand or contract, and/or a skirt attached to the flexible frame and configured to form an enclosure between the flexible frame and the hopper weldment.

Abstract: An operator station is provided. The operator station may include a platform. The platform may at least partially extend along a plane. The operator station may include a first linkage member attached to a first portion of the platform and a second linkage member attached to a second portion of the platform. The first linkage member may be pivotal with respect to a first pivot axis, and the second linkage member may be pivotal with respect to a second pivot axis. The operator station may include an actuating member attached to the first linkage member. The actuating member may actuate the first linkage member for pivoting the first linkage member in a first direction and pivoting the second linkage member in the first direction. The platform may linearly translate in the plane during pivoting of the first linkage member and the second linkage member.

Abstract: A milling machine includes a frame, a ground engaging rotor assembly, a moldboard, and a hydraulic cylinder including a piston rod and a piston barrel. The ground engaging rotor assembly is at least partially enclosed by the moldboard. The moldboard is vertically movable via the hydraulic cylinder, and the hydraulic cylinder is coupled to the frame via a dual-trunnion assembly.

Abstract: An enhanced circuit-switched media transmission over packet-switched, or Internet Protocol, access networks. Access legs of calls between terminal devices are monitored at a gateway positioned at the interface between packet-switched and circuit-switched networks. Access legs are identified which connect terminal devices residing in the same access network through monitoring of media data transmission. Terminal devices with identified connections are instructed to communicate directly while the gateway maintains the connection on the circuit-switched network.
