Abstract: An arrangement for an optical instrument comprises two mirrors (11, 12) which co-act in illuminating an object or detecting light rays reflected by or emitted from the ob­ject. One mirror (11) is positioned adjacent the pupil of the instrument and the other (12) of the two mirrors is located in a position for directing transmitted light di­rectly onto the first mentioned mirror (11) or a position for receiving directly light reflected by or emitted by the first mentioned mirror (11). 
     The arrangement may have the form of a scanning device, in which case the first mentioned mirror (11) rotates about an axis (13) which is perpendicular to the symmetry axis (15) of the instrument, and the other (12) of the mirrors is arranged to rotate about an axis (14) which is perpendicu­lar to the first mentioned axis. The distance (R) between the two mutually intersecting axes (13, 14) is equal to the mean distance between the centres of respective mirrors. 
     The first mentioned mirror (11) moves at a frequency within the range of 25-50 Hz, whereas the other mirror (12) moves at a frequency within the range of 0.1-0.3 Hz.

Abstract: The method of incinerating hazardous materials and fluidizable wastes, such as liquids, gases, entrained solid particles, fumes and slurries, utilizes an incinerator (10) in the form of a sudden expansion burner. The incinerator (10) has a relatively small diameter cylindri­cal inlet pipe (22) connected by a circular plate (16) to a rela­tively larger diameter elongated cylindrical combustion chamber (12). A waste injection line (30, 101) passes into the incinerator (10) adjacent the inlet pipe (22) for transfer of incineratable waste therethrough and into the upstream end of the combustion chamber (12). Air inlets (60) connected to a blower (38) also terminate adjacent the inlet pipe (22) for supplying air at a high flow rate to the combustion chamber (12). One or more fuel nozzles (40) extend through the plate (16) into the combustion chamber (12) to provide an overstoichiometric concentration of fuel adjacent the plate (16). The fuel is ignited through an electrically powered, fuel supplied igniter (46) extending into the combustion chamber (12) through the inlet pipe (22). The supply of fuel, waste, air and igniter fuel are monitored. Total combustion of hazardous waste materials is carried very rapidly out by utilizing the present method and incinerator.

Abstract: Switches with a metal case and a plastic base are used as reversing switches, transmission switches, temperature switches or the like, especially in the case of motor vehicles. However, the die-cast zinc of which the switch case normally consists becomes flexible at relatively high temperatures so that the smooth cylindrical plastic base, which is secured only by means of a circumferential lip on the end in the die-cast case, can be detached from its mounting on the die-cast case. According to the invention, this is avoided in a particularly simple manner in that the base (2) of the switch (1) has an outwardly projecting retaining flange (7), in that the circumferential lip (6) rests on an oblique surface (10) of the base, directed outwards from the base (2), and in that on the sleeve (5) surrounding the base (2) there are arranged at least two, preferably three or four, indentations or notches (8), distributed around the circumference of the retaining flange (7), which grip under the retaining flange (7) on the flange side facing the circumferential lip (6) in a securing manner. <IMAGE>

Abstract: A control system (10) for motor vehicle gear-changing transmissions (12) is provided having a manually operable device (28) and an automatic device (30, 34), in each case for generating gear-change control signals. The gear-change control signals are supplied to the force-driving devices for the plurality of windings of a stepping motor in order to switch selected windings on intermittently. When switching a winding on, a reverse current is also triggered which causes the automatically operating device (30, 34) to generate a fault signal if no reverse current is generated by the selected winding. If a fault signal occurs, the generation of further automatic gear-change control signals is suppressed so that transmission gear changes can be carried out only by the application of manually generated gear-change control signals.

Abstract: Waste gases from aluminium smelting processes having a melt phase and a chlorination phase in which chlorine gas is injected into the melt are purified by cooling them, subsequently neutralising them in a main waste gas circuit in a reactor using calcium hydroxide powder and then passing them through a filter for removal of solid components. To reduce the calcium hydroxide consumption and the production of solids unsuitable for landfill, it is arranged that the hot waste gases are passed directly from the chlorination phase into a bypass circuit and via at least one scrubbing step, in which chlorine and chloride residues are scrubbed from the waste gas, and that the purified waste gas is returned to the main waste gas circuit, while the acidic waste water from the scrubbing step is chemically neutralised, and the neutralised water is evaporated by introduction into the main waste gas circuit prior to the reactor, the resulting solids being separated from the waste gas at the filters.
