Patent DE-3904286-A1 (DE)
Title: Method and apparatus for burning waste material
Inventor: SCHOLL GERHARD
IPC: F23G5/12
Filed: 1989-02-14
Abstract: In a method and an apparatus for burning waste material in a firing system for fossil fuels with at least one burner, the proposal is that the waste material should be introduced in a predetermined ratio relative to the fossil fuel into the centre of the flame cone of the burner and burnt there. By means of this method, the flue gases from the waste arising in the centre of the flame cone are heated up as they pass through the outer flame cone to temperatures at which toxic dioxins and furans, for example, are destroyed with certainty. <IMAGE>

Title: Knife for processing a length of meat
Inventor: REIFENHAEUSER UWE
IPC: B26D1/29
Filed: 1989-03-02
Abstract: The knife (1) has blades (2) which rotate around a spindle (3). In order to increase the angular momentum of the knife (1), a mass segment is arranged at the ends (6) of the blades (2). To increase the stability of the blades (2), their ends (6) are connected to a ring (7), which is arranged concentrically with respect to the spindle (3) and to which additional mass segments (9) are fastened. A high rotational energy can be stored in the knife (1), even at a relatively low speed. The centrifugal force acting on the ring (7) and the additional mass segments (9) results in an additional stabilisation of the blades (2) of the knife (1). <IMAGE>

Title: Snap-on hinge mechanism
Inventor: BAREIN NORBERT
IPC: B65D47/08
Filed: 1989-03-22
Abstract: The snap-on hinge mechanism is provided, in particular, in conjunction with a closure or tamper-indicating closure, in particular for containers, and, according to a preferred embodiment, has two parts (41), (42) connected by a film hinge (1) in an articulated manner to one another and to two sections (B-A-B). The film hinge (1) deviates, at least in some sections, from the course of the geometrical pivot axis (S-S). At least one constituent of the lid part (4) is of resilient or flexible design here, at least in some sections. The lid part (4) is connected here to the closure bottom part (3) via a film hinge (5) and is folded over from the opened-up position (position of manufacture) into the closed position, the fixed part (41) of the lid part (4) being firmly connected to the closure bottom part (3). During pivoting, for the purpose of exposing a removal opening in the movable part (42) relative to the fixed part (41), about the geometrical pivot axis (S-S) from one of two stable end positions beyond a dead centre point into the other stable end position, a resilient snap-on effect is achieved. <IMAGE>
