Abstract: A method for compressing and cutting random loaded scrap metal comprises the steps of gravity advancing scrap metal to a cutting zone, applying a first transversal compression to the scrap metal being advanced, guillotine cutting a portion of the scrap metal and concurrently applying a further transversal compression. The machine comprises a scrap metal conveying trough, a transversally movable pressing plunger adapted for traversing the conveying trough and compacting the conveyed scrap metal, a guillotine block for cutting the compacted scrap metal and a guillotine driven compacting block movable perpendicularly to the pressing plunger and cooperating therewith.

Abstract: Metering device for metering a fluid into a liquid to obtain a treatment liquid having variable physical parameters depending on the concentration of the fluid to be metered into the treatment liquid. The device comprises a container having an inlet for the liquid, an outlet for the treatment liquid and an inlet for the fluid to be metered. First valve means provided at the inlet for the liquid are effective to control the flow of the liquid into the container according to the level of the liquid in the container. Second valve means provided at the inlet for the fluid to be metered control the admittance of the fluid to the container.

Abstract: A dispensing device for toothpaste or other paste-like material, comprising an elastically deformable duct arranged within a housing and connected at one end to a container of the material to be dispensed and at the other end to a delivery mouth. Parallel to the duct there is movable a carriage having a member capable of engaging the duct to squeeze it in a given direction, thus causing dispensing of a controlled amount of the material contained in the duct, while simultaneously sucking up therein a substantially equal amount of material. The carriage is operable by a toothbrush or other receiving member which is insertable into the housing below the delivery mouth. The material is dispensed directly on the bristles of the toothbrush or other receiving member while the same travels below the delivery mouth during return of the carriage and toothbrush under the action of a return spring.
