Title: Machine tool for the grinding of cutting tools
Inventor: WITTE ANDREAS
IPC: B24B3/02
Filed: 1986-05-14
Granted: 1987-11-12
Abstract: The machine tood for the grinding of cutting tools has a machine stand 1 on which a holding fixture 2 for the cutting tool and a support 5 for the rotationally driven grinding element 9 are movably arranged. The support 5 bears a pivotable stand 6 and a grinding spindle head 7 movable thereon. The grinding spindle head 7 is pivotable on a circular guide face 10 of the stand 6, the mid-point M of the circular guide face 10 lying on the grinding-spindle axis 8. The stand 6 is pivotable about a vertical axis 11 which passes through the mid-point M of the circular guide face. Consequently, it is possible to move any desired point of the grinding element at a defined distance and angle with respect to the mid-point, i.e. the grinding element performs reproducible and determined grinding movements relative to the cutting tool. A numerical control of the individual movements is thus possible in practice. <IMAGE>

Abstract: A cardiac valve prosthesis in which each closing body has a skeleton line which is curved in the area of the swivel axis. The curved area is followed by a rectilinear area, thus causing a linear cross sectional enlargement in the outlet region of the passage formed by the closing bodies. The opening and closing behavior of the cardiac valve becomes more stable, deadwater ares and vortex formation are largely avoided and natural blood flow is substantially undeviated.
Patent DE-3720362-C1 (DE)

Filed: 1987-06-19
Granted: 1988-07-14
Abstract: In a device of the generic type, for improved control of the filling pressure above the path of movement of rotating dosing chambers (12), which pressure causes dosing errors and disadvantageous eddying in the filling material, a filling chamber (14) is arranged which is delimited, in the direction of movement of the dosing chambers, by an end wall (22) graduated in the form of steps, at the bottom edge of which a stripper (26) co-operating with the dosing chambers is arranged. In order to change, if required, the graduation ratio of the filling chamber and its shape in the region of the stripper, the steps lying closest to the stripper can preferably be designed to be vertically adjustable.

Patent DE-3730591-C1 (DE)
IPC: G09F13/20
Filed: 1987-09-11
Granted: 1988-07-07
Abstract: An illuminated display unit such as a house number, traffic sign, advertisement carrier and the like comprises a fluorescing or photoconductive plate adjacent an edge of which is fitted at least one light-emitting element, in particular a light-emitting diode. The edge is provided with a reflecting layer to prevent emergence of light. Display symbols or their negatives are arranged, as viewed by the onlooker, on the rear face of the photoconductive plate. As a result of the total reflection for a photoconductive plate on the front and back and on the reflecting layer at the edges, the light produced by the light-emitting diode can issue only at the contact surface with the display symbols, so that the light is concentrated very strongly there and a great display brightness is produced. This is even more effective when a contrast surface is arranged behind the plate. In this way great display brightness can be produced with very low electric power, permitting continuous operation or operation with a small number of solar cells.

Abstract: A vertebral-column device that is suitable to be received in an intervertebral space between two dorsal vertebrae, the prosthesis comprising a curved strip of biocompatible material. The width of the strip being such that after placement, the strip makes contact with the vertebrae. The strip is manufactured from a material that can undergo great deformations before permanent deformation arises. The strip is curved in a shape in which the extremities are situated apart from one another and the radius of the curved parts and the thickness of the strip are chosen in such a way that when the strip is bent out into an approximately straight strip, scarcely any permanent deformation arises. Thus, the strip which has been bent out into an approximately straight strip is capable of being introduced into an intervertebral space where the strip assumes its original curved shape.

Abstract: FIELD: rolling of sheet stock. SUBSTANCE: one of hexagon sides rests permanently on metal strip. As stock width is changed, particularly to a larger dimension, the hexagon turns one facet thus withdrawing the used facet and putting a new facet in contact with the strip. This eliminates gaps between the strip and revolving wall of water drain. As all the facets of the hexagon become worn, the latter is replaced. This is cheaper than each time changing or repairing the revolving wall. EFFECT: reduced operational expenses and higher quality of rolled stock due to constant contact of the revolving wall with said stock irrespective of its width. 2 dwg
