Title: Device for compacting refuse composed of packaging material
Inventor: BERGMANN HEINZ
IPC: B30B3/00
Filed: 1989-02-08
Abstract: A device for compacting refuse composed of packaging material and easily pressable waste in containers which are open at the top by means of a driven compaction roller which engages in the container, circulates around the refuse, executes a movement in relation to the container during compaction as the quantity contained by the container increases and is arranged on an arm, which overlaps the container, of a stand and on a shaft which extends vertically in that position, a lifting device being provided which allows the roller to be raised under its own weight, is to be designed in such a way that awkwardly shaped and bulky refuse can also be compressed without difficulty using said device. To achieve this, provision is made according to the invention for at least one connecting element to be displaceably arranged which extends within the roller in a guide provided there diagonally through the axis of the roller, penetrates the roller and is able to emerge from two diametrically opposite apertures in the outside surface of the roller, the collecting element being sufficiently long for it to emerge on the opposite side of the roller when it is pressed into one side of the outside surface of the roller.

Patent DE-3936186-A1 (DE)
Inventor: HAUF HORST
IPC: B42C5/04
Filed: 1989-10-31
Abstract: The use of types of paper which are difficult to process necessitates preparatory steps such as notching or roughing in order to ensure durable bonding. Conventional processes and devices generate unilateral forces transversely to the pile of sheets which affect the guiding of the pile of sheets, their subsequent gluing and the durability of the binding. These transverse forces can be compensated by the new process and the concrete device. A processing device uses at least two identical, counterrotating partial devices (I, II) with processing tools in such a manner that the components of force (QLi, QRi) produced transversely to the pile of sheets (10) by the two partial devices act in opposite directions and compensate the transverse forces.

Title: Automatic demoulding equipment - in which overall controller moves two arms longitudinally in different directions, grips injection moulding with one, and utilises motion
Inventor: SUHLING PETER ING GRAD
IPC: B29C45/42
Filed: 1989-10-31
Abstract: Automatic manipulating equipment, and particularly equipment for removing products from their productive machinery, and notably for demoulding injection mouldings, has at least one longitudinally moved arm with an end device to pick up the article concerned. The arm has a component and a secondary arm moving relative to it longitudinally which has a pick-up for the article; the position between this component and the second arm is recorded by an instrument which is linked to a controller for the drive of the arm. ADVANTAGE - The equipment utilises the force which grips the  article being demoulded to move the arm. It minimises the loads required even when using high accelerations or very heavy arms. The figure shows the first arm (18), toothed (20) for its drive mechanism (19); it (18) holds (23) a section (24) which has its own drive (26) for vertical motion. The bottom of this section (24) has a member (28) with a secondary arm (27) which moves, its position being recorded by the instrument (29). A signal from the instrument (29) is passed to the regulator (31) and there converted to a control action on the drive (19). Force (F) on a moulding moves the secondary arm (27), whereby its position is signalled to the regulator (31).
