Patent FI-82538-B (FI)
Title: Shut-off element of hard material with low coefficient of friction
Inventor: KNAPP ALFONS
IPC: C04B41/87
Filed: 1986-09-22
Granted: 1990-11-30
Abstract: A process for manufacturing a pair of seal members (10 and 12) such as a pair of disks which control the fluid flow of a faucet. The two seals are formed of a moderately hard material (14), such as stellite, ceramic materials, metal materials or synthetic materials, which can be precisely ground to a particular finish. At least one of the seal members (10) is coated with a thin layer (16) of very hard material such as silicon carbides, metal carbides, metal nitrides, or cubic crystallographic lattice carbons. The coating layer is applied through either physical or chemical vapor deposition. This process provides seal disks with low friction coefficients thereby eliminating the need to provide a lubricant between the cooperating surfaces of the disks. In addition, adhesion between the seals is eliminated despite the smooth surface finish of the disks. Thus, the disks formed through the process improve operation of the faucet or valve utilizing cooperating seal disks.

Abstract: Methods and device in X-ray diagnostics, in particular in mammography, for regulation of the exposure of a film (F) or equivalent to an optimal level. In the method the radiation that has passed through the object (2) of photography is measured by means of an arrangement of detectors (4a...4n) and, based on this measurement, the time of exposure regulated. The measurement signals are passed from the detector (4a) or from different detectors (4a...4n) to the amplifier (5a...5n) of each detector's own. By means of the control system, which has been brought into a particular calibration state, the amplifications of the amplifiers (5a...5n) are regulated to the levels required by the exposure of different objects of photography. In the method a reference signal (VS) variable in relation to time is employed, said reference signal being defined by means of an initial value (BV) and of angle points (A1...An) and of angle coefficients between said angle points. When new apparatus settings and/or means are being taken to use, said initial value (BV) and/or one or several of said angle coefficients (A1...An) is/are changed.
