Inventor: NICKEL HARALD P
IPC: B60B3/02
Filed: 1996-11-27
Abstract: An improved method for fabricating a vehicle wheel from a one-piece sheet metal blank involves a nine station transfer die. In a first station, a sheet metal blank is drawn into a dish-shaped wall, a cylindrical outside wall, a first contour, and a first side wall. In the second station, the dish-shaped wall is reverse drawn to form a hub and an inside wall, and a valve hole is punched into the first contour. In the third station, the hub is flattened to be substantially perpendicular to an axial centerline of the partially fabricated wheel, and an outer peripheral edge of the first side wall is trimmed. In the fourth station, the inside wall is laterally formed so as to be in contact with the outside wall, and an outer peripheral edge of the first side wall is wiped over to form a flange. In the fifth station, a second contour is laterally formed. In the sixth station, a first offset and inner and outer hub-stiffening embosses are drawn into the hub. In the seventh station, a second offset is drawn in the hub, and a second side wall is laterally formed to complete a tire engaging rim. In the eighth station a center aperture and a plurality of wheel mounting holes are punched in the hub. Finally, in the ninth station, the center aperture and the wheel mounting holes are extruded, and a plurality of rim-stiffening embosses are laterally formed in the rim.

Abstract: A simulation method for imaging of an underwater object is
performed by simulating the object with a test panel having several strips
of different brightness, and irradiating the test panel with a pulsed laser
beam having three primary colors. From the reflected beam pulses,
contrast values of the test stripes are computed for reflected pulses of each
color in relation to the turbidity and visibility distance. The method may
be used in conjunction with an imaging apparatus having a laser
generation device which produces three primary colors of three different
wavelengths; a laser beam detection device to receive the reflected beam
pulses of respective primary colors, to determine intensities of the
reflected beam pulses of respective primary colors, and to output three
primary color signals to an image monitoring device. The imaging system
may also be arranged so that a laser irradiation device, a laser beam
detection device and an image monitoring device are all placed underwater
in a submersible vessel with appropriate provisions for hydrostatic
pressure and unmanned operation.

Abstract: On prépare des polyols catalysés au moyen d'un catalyseur double métal au cyanure (DMC) selon un procédé amélioré consistant à effectuer l'apport en continu d'un initiateur pendant la polymérisa tion de l'époxyde. Ce procédé implique l'addition en continu d'un initiateur (Sc) et, éventuellement, l'utilisation d'un initiateur chargé initialement (Si). Ce dernier représente au moins environ 2 % en équivalence de la totalité de l'initiateur utilisé. Ce procédé permet d'utiliser de l'eau et des initiateurs de poly ols à poids moléculaire bas dans la synthèse de polyols catalysés par DMC. De plus, ce procédé permet d'obtenir des polyols de polyéther possédant des teneurs limitées en queue de polyol à poids moléculaire élevé, laquelle pourrait autrement avoir un effet négatif sur le traitement de la mousse de polyuréthane.
