Abstract: A muscle-powered machine has a frame, a drive wheel rotatably mounted on the frame and rotatable in a plane defining a normal straight-ahead travel direction, and a drive pedal engageable with a foot of a user of the machine and having one end pivoted on the frame forward of the user's foot. The pedal is pivotal through an acute angle on the frame between an upper position and a lower position with the pedal extending at an angle of 90° ±10° to a lower leg of the foot on the pedal. A quotient of the maximum vertical travel of the pedal measured perpendicular to the pedal in its lower end position and the sine of the angle is greater than the length of the pedal measured radially of its pivot. A drive connected between the pedal and the drive wheel converts oscillation of the pedal between its end positions into rotation of the wheel.

Abstract: The invention relates to a method for filling a horizontal flue coking oven. According to the invention, spinning cells are introduced into the furnace chamber for filling, which comprise a discharge element rotating about a vertical axis. The bulk material is charged onto the spinning cells and the bulk material distributed in the furnace chamber as a result of the rotation of the discharge element. The surface of the bulk material is subjected to a subsequent raking process.
