Date Jun. 5, 1997In a mould-pressing machine, atomizing nozzles with a vortex chamber deliver atomized liquid mixed with air through outlet apertures. The atomizing air nozzle or nozzles are constantly supplied with compressed air through a pressure conduit while the liquid nozzle solely receives liquid under pressure through a liquid channel and a slave valve controlled by the liquid pressure in the periods during which injection of liquid mist is desired. A first (upstream) vortex chamber is provided upstream of a second (downstream) vortex chamber, and between these two vortex chambers a flow path is provided to interconnect the two vortex chambers, through which flow path the liquid mist having been formed in the first vortex chamber is forced to pass and change its direction and velocity of flow at least one, thus reducing the droplet size of the liquid mist.

Abstract: Reactive antioxidant compounds, able to stabilise organic polymers, contain in their molecule a sterically hindered phenolic group and a hydrolysable silyl function. 
<??>In stabilising organic polymers, said reactive antioxidant compounds can be hydrolysed at the silyl function with the formation of silanol groups, which are made to interact in order to form complex resinous stabilising structures. These latter are added in stabilising quantities to the polymer to be stablised. 
<??>According to one particular embodiment, the hydrolysis at the silyl function and the formation of the resinous structure take place spontaneously within the polymer to be stabilised. 
<??>According to a further embodiment, the reactive antioxidant compound is added to the polymer after being stably supported on a solid support by reaction with an inorganic solid having surface hydroxly groups. 
<??>According to a further embodiment, the reactive antioxidant compound is made to interact with the polymer so that the stabilising compound becomes chemically bonded to the polymer chains. 
<??>In all cases, stabilised polymers are obtained containing the antioxidant compound in a form which is not removable from the polymer. 
<??>The process for preparing the reactive antioxidant compounds and for preparing the stabilised polymer compositions are also described.

One of the clutch halves has substantially radially oriented projections (3) which consists of a rigid, wear-resistant material and are partly embedded in an elastically deformable carrier (2). Their projecting ends engage opposite recesses (6) in the other clutch half. Due to the elasticity of the carrier material the projections will, in response to the magnitude of the torque transmitted by the clutch, tend to deviate from their initial, radial positions and, when a predetermined torque limit value is exceeded, assume positions where the clutch starts skipping.

Abstract: A device for the transportation of air by means of so-called electric wind comprises at least one corona electrode K and at least one target electrode M located downstream and at a distance from the corona electrode. The device also comprises a DC voltage source 3 with two connections connected to the corona electrode and the target electrode respectively. The design of the corona electrode and the voltage of the voltage source are such that a corona discharge generating air ions takes place at the corona electrode. The creation of an ion flux which moves in a direction upstream from the corona electrode and thereby counteracts the required direction of the air transportation is prevented by means of effective screening of the corona electrode in such a way that the product of the strength of any ion flux moving upstream and the distance which the ion flux moves is practically zero or at any rate considerably less than the product of the strength of the ion flux and the movement in a direction downstream from the corona electrode. The distance from the corona electrode to that part of the target electrode which receives the predominant part of the ion flux is at least 50 mm and preferably at least 80 mm. <IMAGE>

Abstract: An assembled voltage controlled oscillator VCO in the oscillation circuit of which a strip conductor is used, must often be tuned to obtain the required frequency. Normally the active length of the resonator strip is changed. In known methods measurement of the frequency and shortening of the active length of the strip are carried out in turns. According to this invention the following procedure is carried out. Several holes are drilled in the end of the resonator strip 1, after which the oscillator is assembled. Then measurements are taken to find at which hole the earthing to the earthing strip 5 gives the correct frequency and a rivet 4 of conductive material is placed in the hole which earths the resonator strip 1 to the earthing strip 5. <IMAGE>
