    摘要: A method and an apparatus for the production of industrial lead oxide involving mixing molten lead and air in a reactor. A particularly advantageous, having a desired particle size can be obtained with a PbO content of considerably more than 99%. The lead flow is introduced at a constant and even rate and the air flow is altered very slightly in order to maintain the pre-determined reaction temperature having fluctuations of a maximum of .+-.5.degree. C.The constant and steady infeed of the lead flow is achieved by using an apparatus according to the invention. The apparatus, which is situated above the reactor, includes a supply vessel charged with molten lead from a melt container, the supply vessel having an exchangeable nozzle which is provided with a control-operated cleaning pin. The nozzle extends into a reaction space and the supply vessel is connected to the melt container via a feed line and an overflow. The nozzle can also be of a known spray nozzle type which is fed with heated compressed air via a line running through the said melt container.

    摘要: In a process and a device for manufacturing partially oxidized lead dust from lead pieces, the natural pile of dissociated coarse and fine material formed in a rotating drum is mechanically disturbed by radially extending guide plates in the interior of a drum which plates are arranged in pairs and displaced toward each other by 180.degree. in the direction of the circumference of the drum and the individual plates of each pair of plates are spaced axially apart, by which arrangement the efficiency of the process and the product quality are greatly improved.

    摘要: An electric motor with attached tachogenerator wherein the tachogenerator may be attached to electric motors of varying types without significantly changing the housing or motor shaft bearing plate configuration and while maintaining the required environmental protection. The rpm signal generator of the tachogenerator is placed onto a motor shaft end portion which extends out of the motor housing through the shaft bearing plate and is enclosed by a closable housing accommodating a detector, e.g. a coil. The housing is latchable, for example by means of detent hooks, to the bearing plate or motor housing. The arrangement is particularly useful for electric motors where dust free and liquid tight protection is required.
