    摘要: Soft quartz glass having low viscosity and a low thermal coefficient of expansion, high electrical insulation capability and free from release of contaminants, when used as a bulb of an incandescent lamp or as an envelope in an arc vessel of a discharge lamp, is a quartz glass made of ultra-pure quartz (SiO.sub.2), for example having a purity of 99.99 mol-%, doped with stoichiometric compounds of alkaline earth oxides with boron oxide, optionally also with a small quantity of Al.sub.2 O.sub.3 in an overall quantity of the doping substance of between about 0.05% to 0.8%, by weight.

    摘要: An arrangement for use on a vehicle, especially truck for transporting portable bridges, with the sections of a portable bridge being adapted to be arranged one above the other on support frames, and being adapted to be received on the support frames, by means of a bridge placing apparatus. The support frames are distributed over the effective length, behind the cab of the particular truck, and secured to the frame or the like thereof. The support frames are provided as independent components, releasably securable to the vehicle frame or to a loading platform, and the support frame immediately adjacent the cab is provided with a pivot drive arrangement for moving the sections of the portable bridge in the longitudinal direction of the vehicle.
