Abstract: A vehicle illumination system includes at least one electroluminescent light band arranged on the shell of the vehicle body. The electroluminescent light band is arranged in an indentation of the vehicle body shell such that, on its exterior, it extends essentially flush with respect to the adjoining shell area, continuously from a front head light to a rear light. It may be operated as a moving light during a certain driving maneuver, such that its moving direction corresponds to the driving direction of the vehicle.

Abstract: A viscosimeter for measuring the viscous and elastic properties of a visco-elastic substance continuously in or on a process flow comprises a measuring member which extends into the substance and which is displaced with a reciprocating oscillatory movement, whereby a defined constant shear flow occurs between the measuring member and the said substance. The viscosimeter further includes a connecting linkage connecting the measuring member to a drive, the end portion of the connecting linkage which carries the measuring member and which is enclosed by a bellows member being in the form of a carrier member extending normal to the axis of rotational symmetry of the measuring member. The measuring member is connected to the end of the carrier member in such a way that its geometrical axis coincides with the axis of rotational symmetry. The bellows member only performs pure angular movements which give rise to only very slight measuring errors and which enable it to enjoy a long service life.

Abstract: In a rotary viscometer comprising a variable speed drive motor including a speed indicator, such as a tachogenerator or a similar device, and a measuring shaft driven by an output shaft of a rotor of said motor and carrying a measuring member immersible in a medium of which the viscosity is to be measured, the motor stator is rotatably displaceable against the action of a spring, the displacement being a measure of the viscosity. The driving connection between said motor and measuring shaft comprises at least one pair of exchangeable gears or toothed belts and said spring is exchangeable for one having a different spring characteristic.

Abstract: A cover for lights, especially automobile lights, wherein at least a part of the cover which is located within a flat area of a reflector opening of the light when the cover is installed is provided with a number of individual sections. The sections are staggered in a stepwise fashion within a plane which is horizontal in the installed position and/or in a vertical plane with the sections extending in a direction opposite to an intended direction of travel of the atuomobile.

Abstract: A rapidly rotating shaft for a wire-rope-stranding machine or the like, comprising a plurality of tubular sections interconnected by flanged coupling sleeves, has a journal bearing for each coupling sleeve whose inner race is unitary with that sleeve while its outer race is a ring closely surrounded by a cylindrical housing. The ring and the housing are provided with aligned bores for the introduction of lubricant; an annular cage between the two races, having a multiplicity of peripherally spaced pockets engaged by respective bearing rollers, is provided with apertures between these pockets facilitating the passage of the lubricant to the inner race.

Abstract: A rotary viscometer is described in which the force measuring device for measuring the force acting on a measuring surface, normal to the surface thereof, is contained within a separate housing releasably connected to the remainder of the apparatus.The force measuring device comprises a beam and the force is communicated to the beam by an intermediate thrust member which is stiff and does not yield to axial loads but will move readily to other directions to accommodate misalignment.

Abstract: An improved apparatus is provided for measuring the viscosity of a liquid comprising a rotatable container means; means for rotating said container means at a desired speed; a freely rotatable member within said container means, said container means and said member defining a volume therebetween for receiving liquid to be measured; a third bath surrounding said container means for maintaining said container means at a desired constant temperature; means for measuring torque of said member when said volume is charged with liquid to be measured and said container means is rotated by said rotating means; and a bearing made from a material having a high thermal conductivity and located between and contacting said container means and said fluid bath to facilitate relative rotation therebetween.
