Patent EP-0411204-A1 (EP)
Inventor: SCHMITZ GUENTER DR-ING
IPC: G01N33/28
Filed: 1989-09-27
Abstract: A method for the determination of the alcohol content and/or the calorific value of fuels by measuring electrically measurable quantities in a measurement cell, containing the fuel, for determining the relative permittivity of the mixture in the cell as the characteristic quantity of the alcohol content or of the calorific value is improved, in particular, for application in internal combustion engines. This is achieved by determining the relative permittivity by measuring the capacitance of a capacitor formed in the measurement cell, whose dielectric is formed by fuel in the measurement cell, the capacitance being determined by circuit techniques and/or by calculation independently of the effect of the conductivity of the fuel.

Abstract: A method for detecting a predetermined pointer position in a display device is specified, the pointer of which is moved by a rotating-field motor via a transmission. A display device is also specified. In display devices of this type, it is possible that the relationship of the driving system to the actual position of the pointer is not defined when the system is started from an arbitrary state. It is the object of the invention to restore the absolute relationship between the pointer position and the driving system without using external sensors. For this purpose, the pointer is moved against a stop and the blocking of the pointer movement is detected. The display device has a rotating-field motor (1), the rotor (2) of which has a magnet (3) and moves a pointer, and the stator of which has at least two coils (4, 5) which are offset in angle with respect to one another and which are electronically connected to a control device (6). At least one change-over switch (13) is provided which interrupts the connection of one of the coils (5) to the control device (6) and connects this coil (5) to an evaluating device (14). <IMAGE>

Abstract: A method is proposed for recovering high-temperature exhaust gases of high inflammability in terms of car­bonaceous concentration from the partial combustion, at atmospheric pressure or near atmospheric pressure, of a mixture of pulverized bituminous or subbituminous coal and air as oxidizer gas, enriched with oxygen gas, in a combustor apparatus (1) having a cylindrical combustion chamber with a tangential injection duct (2), through which the fuel mixture is introduced into the combustion chamber to develop into a rapidly swirling vortex opti­mizing burning over a short period of time. As a result, high-temperature, inflammable exhaust gases are generated, of which the heat is recovered to produce steam in a boiler (27). After losing portion of their heat to the boiler (27), the inflammable gases, follow­ing purification by a filter (37) and desulfurization unit (39), are recovered for subsequent thermal use in boilers metallurgical or other chemical processes. The ash and other non-combustible products present in the gases are caused to move out outwardly in the combustion chamber as molten slag, forming the outermost part of the vortex, and flow down along the inner wall of the combustor apparatus (1) into its bottom where the slag is collected through a tapping port (4) at the bottom.

Abstract: In order to check the snapping in of the pins of a multiple-pin connector, the latter is placed in an interchangeable support (19) mounted on the body (12) of a device furthermore comprising a member (20, 21) capable of being displaced towards the connector by means of a lever (26). The member (20, 21) supports checking pins (42a, 42b) which are thus brought into contact with some of the pins of the connector in order to verify the correct snapping in of the latter via calibrated springs (50). Since the number of the checking pins (42a, 42b) is considerably less than that of the pins of the connector, a plurality of checks are made, separated by rotations of a part (21) of the member (20, 21). The checking positions are fixed by indexing means (60, 64). <IMAGE>
