Abstract: ABSTRACT OF THE DISCLOSURE               A furnace has a filling inlet normally closed by a removable cover.  An arrangement is disclosed which opens the filling inlet, then fills the interior of the furnace, and then recloses the inlet all in gas-tight and dust-tight manner in order to prevent the free escape of dust and gases to the ambient atmosphere when the cover is removed from the filling inlet. The arrangement in-cludes a housing surrounding the filling inlet and having a discharg ing port and a first opening separate from the discharging port, and a filling arrangement which is operative for conveying a charge from the discharging port throug- the interior of the housing and into the filling inlet when the latter is opened. A cover-extract-ing arrangement is operative for removing and subsequently reposi-tioning the cover. The cover-extracting arrangement includes a hood which has a second opening and which is movable relative to the housing to and from a position in which both of said openings are juxtaposed in sealing relationship so that the interior of the hood can communicate with the interior of the housing. The cover-extract-ing arrangement also includes an electromagnet which is movable from the interior of the hood through the juxtaposed openings to the interior of the housing at a location adjacent the cover for en-gaging the latter. The electromagnet is operative for opening and subsequently reclosing the filling inlet. Thus, in accordance with the invention, any dust and gas escaping from the filling inlet towards the ambient atmosphere when the cover is removed from the filling inlet are confined within the respective interiors of the housing and the hood. Advantageously, the arrangement is used in conjunction with a battery of furnaces having respective filling in-lets arranged in a row and the cover-extracting arrangement,as a whole is movable into sealing engagement with successive ones of the fillin inlets for filling successive ones of the furnaces.

Abstract: Title of the Invention "A Device for measuring at least one dimension of an object and a method of operating said device"     Abstract of the Disclosure A device for measuring at least one dimension of an object comprises two light channels of which one is intended to receive the object and the other serves as a reference channel.  Light from the two channels is conducted to res-pective photo-electric transducers the outputs of which are connected to a comparison circuit.  The relationship between the relative intensities of illumination of the transducers provides a measure of the dimension of the object.  In order to improve the response characteristics of the transducers they are connected in parallel with mutually reversed polarity and the difference between the electric currents passed by the two transducers is compensated by negative feedback via a resistor connected to the output of an amplifier at the input of which the said transducers are connected.
