摘要:
Glass composition ranges are described which permit the introduction of laser activators into fluorphosphate glass with exceptionally high fluorine content while forming glasses of high crystallization stability and permitting the realization of large melt volumes. The high fluorine content imparts to the glasses an exceptionally low nonlinear refractive index n.sub.2 down to O,4 .times.10.sup.-13 esu.

摘要:
In a belt roller for a safety belt system, a rod assembly has a torsion rod as well as at least one torsion sleeve which surrounds it coaxially. A stopping mechanism is provided with at least two axially offset stopping element sections, which can be adjusted either individually or jointly to the at least one torsion sleeve and to the torsion rod through the use of a control mechanism depending on the energy absorption capacity to be applied.

A motor vehicle is disclosed having a safety belt assigned to a seat and having an airbag system which is assigned to the same seat and has a pressure gas source which can be actuated by means of a deceleration sensor. In order to optimize protection for the seat user in the event of an accident, the invention proposes that at least two pressure gas sources which can be actuated independently of one another are provided, and in that in the event of an accident only one pressure gas source can be actuated by means of the deceleration sensor when the safety belt is being worn, while when the safety belt is not being worn all the pressure gas sources can be actuated so that it is only in this case that the maximum airbag internal pressure is available.

A guide device for a safety belt of a safety belt system for a motor vehicle. A delivery roll is provided from which and onto which the safety belt is wound in a region of the downstream deflector fitting, whereby the guide device, as viewed in a pull out or withdrawal direction of the safety belt, is upstream of a deflector crosspiece of the deflector fitting and is fastened together with the deflector fitting. A guide slot is provided that is narrower than a doubled thickness of the safety belt with a free end of the guide device presenting a runner for the safety belt which runner defines the guide slot with the free end of the guide device. The safety belt passes through the guide slot without deflection and the guide slot or through passage through which the safety belt extends is shifted, with reference to a longitudinal center axis of the deflector crosspiece, by an amount of a radius of curvature of the safety belt that is attainable as a function of a stiffness of the safety belt and retraction force in a wind-up direction in a region of deflection of the safety belt at the deflection crosspiece.

A guide installation for a belt-band adapted to be wound-on and wound-off a magazine roll of a safety belt system which is arranged within the area of an after-connected deflection fitting; the guide installation is claw-shaped and thereby surrounds the deflection web of the deflection fitting with a spacing for passage of the belt-band over a portion of the circumference of the deflection web, whereby the spacing is smaller than twice the thickness of the belt band; at least the inlet portion of the guide installation pointing in the direction toward the magazine roll also includes a section that extends essentially parallel to the extension direction of the associated belt-band.

An electrostatic powder coating system that comprises a booth, the lower part of which is designed in the shape of a V, and a collecting channel (13), connected to a suction device (2) underneath, the booth having two ends, each of which has a pass-through opening for the workpieces. The collecting channel (13) is covered by floor plates (17), which can be walked upon or swung up into a vertical position, and which are provided with exhaust slots (18, 19, 20) extending in the longitudinal and transverse directions, it being advantageous for the total area of the slots be a function of the discharge of exhaust air and the velocity of the exhaust air. The floor plates, which can be swung upward, improve the ability of the booth to be walked on and thus increase the ease with which the system can be serviced and operated. As a result of the way in which the exhaust slots are arranged, the powder residues can be extracted more homogeneously and uniformly and thus in optimum fashion over the entire length of the booth.
摘要:
In a vertically displaceable safety belt fitting, to ensure that, even when high displacement forces occur, a first catch element of the slideably displaceable anchoring element received by a guide rail fixed to the vehicle body executes a downwardly directed movement after it has run up against an associated pawl and after an actuating button has been released, whereby, when the button is depressed again, the first catch element becomes capable of moving the associated pawl away, it is proposed to equip a release element carrying the first catch element with an upwardly directed slot on the same side as the bearing and to provide the release element with a spring which engages on the top side of the release element.
