Patent EP-0495358-A2 (EP)
Inventor: JANNEMANN THEO DIPL-PHYS
IPC: F23D14/62
Filed: 1992-01-04
Abstract: The actuator for the two-stage power regulation of gas power burners is formed by a mixer which is connected upstream of the burner and contains a chamber, into which an air supply and a fuel gas supply open and from which mixing holes of a chamber wall, which is designed as a perforated mixer, lead to the mixture outlet of the mixer. The chamber contains a throttle member which is displaceable in relation to the perforated chamber wall and can be displaced from a full-load position which exposes the mixing holes of the perforated chamber wall into a part-load position, in which the mixing holes of the perforated chamber wall are partially covered by throttle member except for a predetermined smaller passage cross-section which is defined by throttle openings of the throttle member. In the part-load position of the throttle member, a shut-off member, which is displaceable together with the throttle member, closes an additional gas quantity outlet of a gas nozzle forming the opening of the gas supply into the chamber. <IMAGE>

Abstract: In a Bourdon pressure gauge with a circular Bourdon tube as a measuring member, a shaped bursting piece (9) with a sharp tip (10) remote from the sight glass (8) of the Bourdon pressure gauge is provided inside the end of the Bourdon tube in its cross-sectional longitudinal-axis plane, which tip (10) is formed at an angle of 90 DEG to the bending radius of the circular Bourdon tube (4). This tip pierces the wall of the Bourdon tube (4) before its bursting pressure is reached so that, at an energy level which is still relatively low, a limited quantity of the substance to be measured can escape and can be diverted in a safe direction. <IMAGE>

Abstract: Disclosed are a method and an apparatus for forming a specular protective film in which the intensity of reflected light is made even with a variation in the angle of incidence of the incident light. 
     In the anodic oxidation treatment, the current value applied to a plurality of specular parts is sampled at a predetermined interval (S301), and each sampled value is integrated over time (S302) and the average value is obtained. A comparison is made between an obtained average value and a preset value, and if the average value is greater, the application of current to all the specular parts is stopped (S303). The preset value is the amount of electricity conducted to form an anodic oxide film having a film thickness corresponding to a desired reflectance which is determined from the relation between the preset film thickness of anodic oxide film and the reflectance. Also, a process for checking to see whether or not the voltage produced by applying the current to each specular part at the start of anodic oxidation treatment is at a predetermined rise slope (S304 to S310), and a process for correcting the current applied to each specular part so as to be equal to the average value during the anodic oxidation treatment are provided (S311 to S315).

Abstract: At the location in a colour channel (2) at which a colour signal (Fe) is transmitted and a colour interference area forming a colour fringe with wrong colours exists at colour discontinuities, the colour channel (2) is split into a delayed channel section (10) and an undelayed channel section (11) and the outputs of these channel sections are connected via a channel switch (12) to the output (3) or to the continuation of the colour channel. The delayed channel section contains a delay line (13) having a delay time (TK) which is greater than the width of the colour interference locations in time. At a colour interference area detected by a colour discontinuity detector (15), the channel switch is switched over during a predetermined switching time (TS) in such a manner that it transmits, instead of the disturbed area of the delayed colour signal in the delayed channel section of the colour channel, an undisturbed area of the undelayed colour signal from the undelayed channel section. In the case of an additional luminance discontinuity, a luminance discontinuity detector (22) controls the control circuit for the channel switch (12) instead of the colour discontinuity detector. This reestablishes undisturbed colour discontinuities in the transmitted colour signal. <IMAGE>

Abstract: Apparatus for measuring the combustion characteristics of a gaseous fuel. Wobbe index and calorific value are measured with a fast response time by maintaining a stochiometric mixture in a mixer (10) supplied with the gaseous fuel at a constant pressure together with ambient air. The pressure of ambient air is controlled by measuring the residual oxygen from combustion of the mix and employing variations in that measured value to control the ambient air supplied to the mixer. The control signal for the ambient air is proportional to the Wobbe index. A separate measurement of the oxygen in the stochiometric mix provides a signal proportional to the calorific fuel value.
