Title: Chopping knife
Inventor: GRUEMMER ANTJE
IPC: B25G1/06
Filed: 1988-08-03
Abstract: The invention relates to a chopping knife for comminuting greens and other vegetables. A very great variety of chopping knives are already known. Known chopping knives of this type are not suitable for preliminary cutting which must precede any comminution process. A second knife is therefore necessary for this. It is difficult to clean chopping knives, especially double-bladed knives, and it is very easy to injure oneself in so doing. Their size makes it difficult to deposit them in conventional cutlery boxes. The chopping knife according to the invention is characterized in that it has a blade (1) with a straight non-cutting edge (1a), a mounting element (3), a guiding element (4) and a tube (2) which acts as a handle. The mounting element (3) is fixedly mounted to one end of the blade (1), while the guiding element (4) can be displaced longitudinally on the blade (1). The tube (2), which is guided in the mounting element (3), is fixedly connected to the guiding element (4). The distance (2b) between the tube (2) and the non-cutting edge (1a) corresponds to the thickness of the back of a human hand. <IMAGE>
Patent DE-3828830-A1 (DE)
Inventor: KNOCH MARTIN DR ING
IPC: A61F2/24
Filed: 1988-08-25
Abstract: In a heart valve prosthesis in which the inner surface (10a) of the valve ring (10) narrows continuously in the direction of flow, there is provided a special mounting of the closing elements (11). Sector-shaped recesses (18) are located in the valve ring (10), and into each of them an elongate mounting peg of the closing element (11) projects.
