Developing apparatus including rotary member for accommodating variable combinations of developing sleeves and balance weights

Abstract
A developing apparatus for developing an electrostatic image on an image bearing member includes a rotary member including a plurality of mounting portions, to which a plurality of developing devices and a plurality of balance weights are detachably mountable. The rotary member selectively shifts a mounted developing device to a developing position opposite to the image bearing member. A developing process is performed in a first mode in which developing devices are attached to all the mounting portions, and in a second mode in which a developing device is mounted to at least one of the mounting portions, and no developing devices are mounted to the remaining mounting parts, and wherein, in the second mode, balance weights are mounted to the remaining mounting portions. An image forming apparatus includes an image bearing member and the developing apparatus.

Method of and apparatus for counteracting the lack of balance of parts in a cuttoff for cigarettes and the like

Abstract
Lack of balance of a crank mechanism, which reciprocates a ledger having one or more guides for one or more cigarette rods or filter rods each issuing from a maker and being subdivided into a row of cigarettes or filter mouthpieces, is at least partially counteracted by at least two counterpoises one of which orbits about the axis of the crank mechanism in a first direction and the other of which orbits, in a second direction counter to the first direction, about a second axis laterally offset relative to the axis of the crank mechanism. A third counterpoise can be mounted for orbital movement about the axis of the crank mechanism and, if utilized, is angularly offset relative to the first counterpoise. The prime mover for the crank mechanism orbits the first and third counterpoises in the first direction, and the second counterpoise in the second direction.

Balance shoe

Abstract
An improved balance shoe is described. There is a balance shoe housing, wherein there is a pivot member. The pivot member forces at least one side support member against the interior surfaces of a window jamb channel when said window is tilted. The pivot member comprises a base section having a top surface and a bottom surface, said top surface having at least one pivot member extending therefrom, said pivot member being adapted to force said support member against the interior surface of said window jamb as said pivot member is rotated due to the tilting of the window sash.
