  • Patent number: 11512017
    Abstract: In known methods for producing a glass component, a void-containing intermediate product containing doped or non-doped SiO2 is inserted into a sheath tube composed of glass, which has a longitudinal axis and an inner bore, and is thermally treated therein. In order to subject the intermediate product to a thermal and/or reactive treatment that is reproducible and uniform in its effect from this starting point, it is proposed in one embodiment that into the sheath tube's inner bore a first gas-permeable gas diffuser is inserted which is displaceable along the sheath tube's longitudinal axis and is pressed against the intermediate product during the thermal treatment.

  • Publication number: 20170252584
    Abstract: An assembly includes first and second ropes and a suspension element. The first rope is securable to a first attachment in a work area. A person can be coupled to the first rope. The second rope is available for lowering the person. The suspension element is secured in a securing region. A force-transmitting coupling is creatable between the second rope and the suspension element. The first and second ropes are coupled to each other over a first lowering region. The second rope is decoupleable non-destructively from the first rope from an end of the first lowering region. A person can be lowered in a second lowering region by the second rope. The weight of the person in the second lowering region is transferable from the second rope via the suspension element to the securing region.

  • Publication number: 20060107693
    Abstract: The invention relates to a previously known method for producing synthetic silica glass, comprising the following steps: a gas stream containing a vaporizable initial substance, which can be converted into SiO2 by means of oxidation or flame hydrolysis, is formed; the gas stream is delivered to a reaction zone in which the initial substance is converted so as to form amorphous SiO2 particles; the amorphous SiO2 particles are deposited on a support so as to form an SiO2 layer; and the SiO2 is vitrified during or following deposition of the SiO2 particles in order to obtain the silica glass. The aim of the invention is to create an economical method for producing synthetic silica glass, which is characterized by a favorable damaging behavior towards short-wave UV radiation while being particularly suitable for producing an optical component used for transmitting high-energy ultraviolet radiation having a wavelength of 250 nm or less.
