Abstract: A magnetic brush development apparatus for applying pigmented marking particles to a latent image charge pattern on a dielectric member. The magnetic brush development apparatus comprises a housing defining, in a portion thereof, a sump for containing a mixture of magnetic carrier particles and pigmented marking particles. A mixer is located in the sump of the housing for mixing magnetic carrier particles and pigmented marking particles so as to effect a triboelectric attraction of the pigmented marking particles to the magnetic carrier particles. The mixed magnetic carrier particles and attracted pigmented marking particles are attracted to an intermediate member, transported by the intermediate member from the sump, and then separated by the intermediate member such that the magnetic carrier particles are returned to the sump.

Abstract: A hand cart comprises a truck and an upwardly open container mounted on the truck. The truck has an elongate frame provided at one end thereof with a handle and at the opposite end thereof with a nose, against which the container abuts with projections on the front of the container engaging in openings at the base of the nose, and a manually actuable clip or the like is provided for releasably securing the rear of the container to the frame. With the container attached to the frame, the cart can be used as a wheelbarrow and, with the container removed, the truck can be used by itself. A detachable nose extension and a detachable bag support are disclosed and the truck can be disassembled for flat packaging.
