    摘要： The roller exhibits a support body which is provided with a plurality of support disks. Insulating layers are arranged between the support disks. A heat-resistant cable surrounding the support body in several coils is embedded in each insulating layer. The insulating layer consists of fiber material which is sprayed on at the same time as the cable is wound around the support body. The cable provides a firm and lasting connection of the insulating layer to the support body.

    摘要： The invention relates to an emergency running ring for pneumatic tires mounted on vehicle rims. A lubricant is contained in cavities formed by virtue of the shape of the ring, or is contained in auxiliary members mounted in openings in the ring or mounted on the surface of the ring. In all instances, the loss of tire pressure due to emergency conditions causes the lubricant to be released so as to reduce the friction between the inner face of the tire cover and the ring.

    摘要： An emergency operation ring for tubeless pneumatic tires on motor vehicles made of an elastomeric material and mounted on a rim by means of axial clamping pressure. Two support sections extend diagonally upwards and outwards from the base section and define a circumferential channel. The support sections have step shaped outer flanks set back with respect to the base section. At least one circumferential groove is provided contiguous the circumferential channel, and slipping agent is positioned in the groove or grooves. Sealing lips close off the groove and slipping agent when the tire is intact. The wheel load working on the support sections at the beginning of an emergency operation brings the sealing lips into an open position, whereby the slipping agent is released and lubricates the surfaces of the pneumatic tire and the emergency operation ring in contact with each other.

    摘要翻译： 机动车辆上的无内胎充气轮胎的紧急操作环，由弹性体材料制成并通过轴向夹紧压力安装在轮辋上。 两个支撑部分从基部向对角地向上和向外延伸并且限定圆周通道。 支撑部分具有相对于基部部分设置的阶梯形外侧面。 至少一个圆周槽邻近圆周通道设置，滑动剂定位在槽或凹槽中。 当轮胎完好无损时，密封嘴唇会关闭凹槽和滑动剂。 在紧急操作开始时在支撑部分上工作的车轮负载使得密封唇处于打开位置，由此滑动剂被释放并润滑充气轮胎和紧急操作环的表面彼此接触。

    摘要： A process for the preparation of a pulverous preparation having a finely divided carotenoid, retinoid or natural colorant is provided, which process comprises the steps of: a) forming a suspension of the active ingredient in a water-immiscible organic solvent optionally containing an antioxidant and/or an oil; b) feeding the suspension of step a) to a heat exchanger; c) heating the suspension to 100-250° C., whereby the residence time in the heat exchanger is less than 5 sec to provide a solution; d) rapidly mixing the solution of step c) with an aqueous solution of a swellable colloid and optionally a stabilizer such that the resulting mixture is at a temperature in the range of 20-100° C.; e) removing the organic solvent; and f) converting the dispersion of step e) into a pulverous preparation; where steps b) to f) are carried out continuously and in sequence.
