A device for transferring air from the upper region of a room through an open doorway to the exterior of that room, such as to an adjacent room. The device includes an open-ended casing or conduit (15) mounted upright to a wall of the room just above a doorway (12), an electric fan (21) mounted in the casing or conduit (15) to draw air downwardly into and through the casing or conduit (15), and a hinged chute (16) positioned at the bottom of the casing or conduit (15) which, when declined downwardly, deflects such downwardly moving air out through the open doorway (12) to the exterior of the room.

Air transfer device

A method and machine for making wire beads for tires wherein the beads comprise one or more wire filaments helically wrapped around a solid metal core ring. The metal core ring is of circular cross section and is supported in a transport mechanism that revolves it about its axis of symmetry while a reel of filaform material is orbited about an axis tangent to a fixed reference line perpendicular to the orbit axis. Thus, the filaform material is wrapped around the core ring in a helical path about the circular axis defined by the center of the core ring cross section. The pitch of the helical wrap is adjusted to place each convolution of the filament in a predetermined spaced relation to the next preceding convolution.
