Abstract: A method for determining one or more characteristics of particles using multiple fluorescence analysis comprises directing an incident light beam at the particles under analysis. The particles include at least three fluorescent markers each having different emission spectra. The incident light beam causes the excitation of the markers by light at a single wavelength whereby different wavelengths of fluorescence are emitted from the particles. Different fluorescence emissions associated with the particles under analysis are simultaneously detected. This method further includes associating the detected fluorescence with one or more characteristics of the particles. An apparatus is also part of the present invention for carrying out the aforementioned method.

Abstract: In a process for the production of a 'water-in-fuel' or 'melt-in-fuel' emulsion explosive a density-reducing agent is introduced and dispersed in the emulsion at an elevated temperature whereat the emulsion is essentially liquid, the explosive is cartridged and then subsequently cooled by means of a refrigerated fluid so that the continuous phase solidifies and stabilises the dispersion of the density-reducing agent in the explosive. Preferably, when the density-reducing agent comprises gas bubbles the explosive is subjected to an elevated pressure before it is cartridged in order to ensure that the sensitivity of the explosive will not be impaired by disturbance of gas bubbles by any pressure drop which might occur during cartridging. 
     The invention also extends to a cartridging machine for cartridging emulsion explosive, the machine comprising a container defining a sealed pressurizable explosives chamber which has an explosives inlet and at least one explosives outlet provided with a positive displacement pump for pumping explosive from the chamber into a cartridge.

Abstract: A transmission is disclosed for rotating the work supporting chuck assembly of a power driven threa­ding machine at low and high speeds. The transmission includes a sun gear (24), a ring gear (56) coaxial with the sun gear (24) and axially shiftable between first and second positions relative to the sun gear (24) and to a fixed clutch component (68), and a plurality of planet gears (40) between the sun gear (24) and ring gear (56). The sun gear (24) is motor driven to provide the transmission input, and the planet gears (40) are connected to and drive an output sprocket wheel (5w) drivingly connected to the chuck assembly. The first position of the ring gear (56) provides clutched in­terengagement thereof with the sun gear (24) for rota­tion therewith, whereby the planet gears (40) rotate therewith to rotate the output sprocket wheel (5w) at a first speed equal to the speed of rotation of the sun gear (24). The second position of the ring gear (56) provides for clutched engagement thereof with the fixed clutch component (68) such that the sun gear (24) ro­tates the planet gears (40) relative to the ring gear (56), whereby the output sprocket wheel (5w) is driven at a second speed which is less than the speed of rota­tion of the sun gear (24). The ring gear (56) is axially shifted between its first and second positions through a yoke mechanism (74) which includes high speed and low speed springs (114,116) by which the clutched enga­gement of the ring gear (56) with the sun gear (24) is achieved with a first biasing force and the clutched engagement between the ring gear (56) and fixed clutch component (68) is achieved with a second biasing force which is greater than the first force.

Abstract: In a device (1) for controlling the quantity of a medium flowing out of a nozzle (14), having a delivery pump (2) and a delivery chamber (10), installed in said delivery chamber there is a control sheath (31) and a control piston (32) cooperating with it, which are displaceably driven with the valve body (13) of the outlet valve assigned to the pump (2) and counter to the force of a restoring spring (38). In addition, the control sheath (31) and/or the control piston (32) is provided with throttle orifices (33), the through-hole cross-sectional surface of which can be adjusted in order to adjust the respective quantity of the medium flowing off through the nozzle (14) and can be automatically changed by relative displacements of the control piston (32) with respect to the control sheath (31) as a function of the position of the valve body (13) of the outlet valve (11). 
<??>As a result, it is possible to set the discharge quantity infinitely over a large range, without the delivery performance of the pump (2) and/or the degree of atomization being adversely affected. In this process, the excess medium delivered by the pump (2) is not fed back into the reservoir, but rather the medium remains in the pumping and/or delivery chamber (6 or 10).
