Title: Extrusion head
IPC: B29C48/09
Filed: 1989-11-28
Granted: 1992-03-11
Abstract: In the head body (11), the mandrel (15) is secured in a passage (13) by means of the legs (17). In the mandrel (15) there is a bore (29) for receiving an axially displaceable control rod (27). With this control rod (27), the core (21) can be axially adjusted with respect to the mouthpiece (35). This adjustment allows the wall thickness of the extruded parison to be set. The rate of extrusion can be controlled by the throttle screw (39). The melt is fed via the melt feed channel (37) to the various passages (13), of which only one is shown in the drawing. The melt stream is divided by the stream divider (43), part of the melt being deflected downwards into the passage (13), while the remaining melt can flow to the next passages (13). The melt flowing into the passage (13) is scarcely hindered by the legs (17) during its downward flow and exits through the die (33) for the purpose of forming a piece of parison. <IMAGE>

Abstract: Chaque ligne dans un bloc de données vidéo est organisée en morceaux continus de pixels blancs, et les morceaux ayant des longueurs inférieures à un seuil donné, sont transformées en pixels noirs. Les données sont ensuite organisées en morceaux de pixels noirs, et la position de départ du morceau de pixel le plus long est notée pour chaque ligne horizontale. L'angle d'obliquité est calculé à partir de la distance de décalage entre les positions de départ des morceaux de pixels noirs notées des lignes successives. L'angle de décalage est calculé à partir de la moyenne d'un ensemble de distance de décalage, l'ensemble étant assez grand pour réduire au minimum l'écart standard RMS de distances de décalage inférieures à une valeur prédéterminée. L'ensemble des morceaux successifs noirs correspond à une configuration en escalier à chaque fois que l'angle d'obliquité n'est pas nul.

Abstract: An angle of rotation detector has a drive unit which supplies 90 degree phase shifted signals to a pair of stator coils and measures an analog output from a rotor coil in a resolver. A calculating device calculates the rotational angle of the resolver using the output of an analog to digital converter receiving the analog output of the rotor. In one embodiment, the calculating device performs a Fourier transform to compute the phase of a fixed frequency component contained in the output of the rotor coil. In another embodiment, the drive unit supplies signals wherein f(T/2 + t) =-f(t) and the calculating device performs a Fourier transform using data from successive half periods of the drive waveform. In another embodiment, the output of the rotor is sampled at 1/4 period of an excitation signal from the drive unit and the calculating device determines the phase difference between the excitation signal and the rotor output. In still another embodiment, the calculating device compares the outputs at two or more points having a fixed time relationship and compares the result to stored reference data to arrive at the angle of rotation. <IMAGE>
