Abstract: The invention relates to an appliance for heating an electroconductive material, preferably one which hardens as a result of this heating process, this material being in the form of a continuous strand which is guided inside a channel (14). In this appliance, a high-frequency generator (23) is provided, two capacitor-plates (30) being arranged on two oppositely-located sides of the channel (14), which sides are formed by walls (10 to 13) composed of an electrically insulating material, these capacitor-plates (30) being staggered by at least their length and being connected to a non-earthed terminal of the high-frequency generator (23), while two further capacitor-plates (31, 32) are arranged on each of the two sides, adjacent to the two capacitor-plates (30), these further capacitor-plates (31, 32) being connected to the earthed terminal of the high-frequency generator (23) and extending along the channel (14) for a distance such that the strand outside the heating zone is no longer at a potential. The appliance can be used, in particular, in a belt-type continuous-moulding unit for the manufacture of blanks for building materials, starting from a raw mixture having a high dielectric coefficient.

Abstract: A continuous process and apparatus for the analysis of a sample containing a peroxycompound in the presence of hydrogen peroxide using known colorimetric techniques, characterised in that a sample is taken continuously, is continuously mixed with a colorimetric reagent and is divided into two streams, and continuous differential colorimetric analysis of the two streams is effected to provide a differential signal, further characterised in that one such stream is heated to such a temperature that the peroxycompound reacts with the colorimetric reagent prior to effecting the differential colorimetric analysis, whereby the differential signal is a measure of the concentration of such peroxycompound.The process and apparatus may be modified in that a third stream is taken not containing any colorimetric reagent, and two differential colorimetric analyses are effected, whereby a further signal is obtained which is a measure of the concentration of the hydrogen peroxide.A control process using a differential signal produced by the process or apparatus may be used to control the addition of peroxycompound to the body from which the sample is taken.

Abstract: An atomizer wheel for use in a spray drying apparatus comprises an interior annular liquid supply chamber (4), from which a number of substantially radial ejection ducts (8) extends towards the external surface of the wheel through a length constituting a considerable portion of the radius of the wheel. The ducts (8) discharge into a downwardly open annular discharge slit (10) at a comparatively short distance from an external wall (12) connected with a wheel cover (2) and whose inner wall surface (13) forms an axial-symmetrical surface of revolution with a substantially linear generatrix forming an angle of not more than 15° with the axis of revolution.The comparatively steep slit wall (13) ensures together with the large length of the ejection ducts (8) that the liquid is atomized at the outlet of the discharge slit (10) with a considerable downwardly directed axial velocity component so that the spray characterstics resemble those of nozzle atomization but with preservation of the general advantages with respect to flexibility and reliability of operation associated with wheel atomization.

Abstract: This invention concerns a multiple loudspeaker with a piezo-electric "tweeter", held up by a means of support which allows the rear wave emitted by the ceramic disk and respective conical diaphragm to be fully exploited, using the main loudspeaker cone as a reflecting surface without overloading the moving coil of the latter. The invention is basically characterized by the fact that the piezoelectric "tweeter" is placed in front of the main loudspeaker cone, without the traditional protection and support basket, but using a different means of support which does not intercept or disturb the rear radiation from the piezoelectric "tweeter", or prevent the forward reflection of the radiation by the main loudspeaker diaphragm.

Abstract: The invention relates to a device for feeding with compressed gas a weapon of the type including a gas reserve, a valve that can move inside a valve housing and a valve seat located in this housing, holding and guiding a valve rod. This device includes an expansion unit interposed between the gas reserve and the valve, consisting of a first expansion chamber communicating with the gas reserve and a second chamber, the chambers being separated by a calibrated orifice. The volume of the second chamber is smaller than that of the first chamber. Both chambers are delimited by hollow cylindrical elements, the cylinder which constitutes the second chamber projecting into the valve housing, its end constituting the valve stop so that the distance between the stop of the seat and the valve stop determines the valve stroke. The motive power that closes the valve consists of the reaction force generated by the impact of the valve against the stop, on the one hand, and of the compressed gas pressure, on the other hand.

The connection piece (22) has an internal thread (23) in which an external thread of a thrust piece (26) engages. By turning the thrust piece (26), the clamping piece (30) is deformed, in order to press against the periphery of the catheter and fix the latter and seal it off relative to the capsule (10). The lateral dimensions of the capsule (10) are not increased by the connection piece (22). The catheter coupling can be easily tightened and released, and it affords satisfactory safety against the catheter being pulled out. <IMAGE>
