Patent SE-8205582-L (SE)
Inventor: KORHONEN A S
IPC: C23C14/48
Filed: 1982-09-30
Abstract: A method for nitriding materials using a glow discharge in an atmosphere of nitrogen or gas mixture at a pressure between 1 . . . 100 mtorr (0.13 . . . 13.3 Pa). Nitriding treatment can be combined with a plasma aided coating process and the temperature control during both processes can be achieved with the aid of separate filament. Nitriding unit can be a separate rig or a part of the coating unit. The method can be used to increase the wear resistance of a work piece by increasing the hardness of its surface. Because of the low pressure used in the nitriding process the same equipment can be used to produce a separate hard and wear resistant compound or alloy coating on the nitrided surface to further increase the hardness of the uppermost surface. The main field of the method is in increasing the wear and corrosion resistance of machine parts and tools.

Abstract: Apparatus for measuring the temperatures of an IR radiation emissive object (12) comprises a housing (8) having an aperture at which is located a body (4) of IR- transmissive material. The body (4) is thermally controlled by a Peltier-effect device (6) and has a first portion (4A) which acts as a window for transmitting radiation from the object (12) to a detector (1) via an optical arrangement (2, 3). A second portion (4B) of body (4) has a covering (5) which prevents transmission of radiation from the object (12). Optical arrangement (2, 3) is arranged to switch the detector (1) alternately to receive radiation from portions (4A) and (4B) of body (4) and the detector output drives a closed loop temperature controller (10) coupled to device (6) in order to provide a zero differential detector output signal, whereupon the temperature of the body (4) is an accurate measure of the temperature of the object (12). The temperature of body (4) is measured by any suitable sensor. <IMAGE>

Abstract: The present invention concerns a method for differential sampling with a fixed sampling frequency fo. When sampling a signal varying between +Vmax and -Vmax, the dynamics of the sampled signal is large close to the ends of the interval but it is small close to zero. The present invention, however, gives a solution to the problem of measuring the fine structure of a signal, with constant resolution over a large amplitude interval. This is done by measuring an analogous signal and on every sampling occasion directly sampling the signal V and forming the difference, Vdiff, between the signal on this sampling occasion and the preceding. The difference is then amplified in order to increase the dynamics in the following sampling and the present signal value is reconstructed from the direct value V of the signal at a starting point, the initial value, and the sum up to the present time of the following differential values Udiff, (6), divided by their amplifications.

Abstract: When the target figure (1) is raised from the horizontal to the vertical position it can be exposed to thrusts and knocks. When it lies protected in a horizontal position a mercury switch (9) blocks an electrical component so that a pulse generator (7) cannot be activated by vibrations in the metal target figure when it knocks against bushes, branches and the like during the raising process. - One second after the target figure has reached the vertical position the blocking by the mercury switch (9) is stopped. When the projectile hits the target figure the pulse generator closes a circuit in the electrical component which starts an electric motor (14) turning an eccentric plate (15). This causes a rocker arm (11) with a hook (12) to release a pin (13) so that the target holder (10) with the metal target figure (1) drops by its wt. to the horizontal position. - (Dwg.1/3)
