In the case of a data transmission system for the exchange of digital data between a central processor unit and several peripheral control modules which are connected to the former by a bus system such that communication is enabled and which are provided for the purpose of activating one each, respectively, out of several safety devices such as airbags or belt tensioning systems, or similar devices, in a motor vehicle, and wherein these peripheral control modules are each provided with one buffer capacitor whose energy content is sufficient for operating the respective module, and the device driven by this module, within specifications over a limited period of time, the bus system is designed as a single wire system for the purpose of achieving a simple setup and reducing installation and fitting costs. In this single wire system the control modules are supplied with electrical operating energy, and digital data are transmintted, by the same line sections. In the data communications mode of the central processor unit and the control modules, the energy supply of the modules is effected by their buffer capacitors. The transmission of the digital data from the central processor unit to the control modules as well as the passing on of such data is effected by modulating a direct voltage whose maximum level U.sub.S is significantly lower than the maximum voltage level U.sub.B up to which the buffer capacitors can be recharged. The recharging of the buffer capacitors is effected in charge mode periods nested in between transmission operation phases of the central processor unit and the peripheral control modules.

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:
A method and arrangement controls a regulating variable which determines the rotational speed difference of a clutch by selecting a phase with a curve of the regulating variable specified by a time function during a transient clutch condition. The beginning and the end of this phase are fixed by one or two influencing variables which are specific to the vehicle. One of the influencing variables is determined by the accelerator pedal actuation and another variable is determined by the clutch temperature.

The present invention provides a process for the production of polymers with an optical position in diagram where refraction index n.sub.D is plotted against optical dispension v.sub.D expedient for an optical use by metathetic counterion exchange, wherein, in a polymer of the general formula: ##STR1## R.sub.1 and R.sub.2, which can be the same or different, are divalent organic radicals, R.sub.3 and R.sub.4, which can be the same or different, are monovalent organic radicals, n is a whole number greater than 2 and y is 0 or 1. R.sub.1, R.sub.2, R.sub.3, R.sub.4, y and n are so chosen that together they form a polymeric basic structure which promotes glass formation and prevents crystallisation, and X.sup.- is a halogen atom. The halogen ion is replaced by an equivalent of a mono- or polyvalent organic or inorganic counterion different from the halogen ion and suitable for the adjustment of the desired solid body properties.Because of their outstanding optical properties (high refractive index in conjunction with low optical dispersion), these polymers are very suitable for a great variety of uses in optics, for example for optical construction parts, such as Fresnel lenses and lightwave conductors, and as optical coatings.
摘要:
A method of accurate friend-foe recognition on the basis of secondary radar through the provision additional special information in both the interrogation device and the responsor device during the formation of their respective signals. This additional information is solely practical and valid for the respective responsor device undergoing interrogation so that the answering signals provided are valued as answers coming from a friend-responsor device. Additional steps of utilizing the time position of the additional information and the uniqueness of such information with respect to a simultaneously available great number of responses makes it still more difficult for a foe-responsor to pass itself off as a counterfeit friend-responsor.

An ink for a recording device, particularly for an ink recording device in which the ink is given off by means of pressure in a direction towards the recording carrier by a recorder head, which is spaced from the record member, and in which a vacuum is formed in the ejecting chamber.
摘要:
Uranium hexafluoride having a high U-235 content is driven out of a transportation container by heating in a correspondingly heated container using a halogenated hydrogen free organic liquid as the heating medium. There is also provided an apparatus for carrying out the process comprising a container having a reflux condenser and an insert for holding the transportation container closed at the bottom by condensate outlet.
摘要:
A self-propelled crossing and floating bridge implement with a main floating body and a plurality of auxiliary floating bodies which when the vehicle is used as a land vehicle are arranged above the main floating body on the deck surface thereof. The auxiliary floating bodies are together pivotable toward one longitudinal side of the implement alongside the main floating body. When the vehicle is used as land vehicle, the auxiliary floating bodies are covered up by a buoyancy body which when the vehicle is to be used as crossing and floating implement is pivotable to a position alongside the other longitudinal side of the implement. In this last mentioned position of the main floating body the latter is covered by a roadway plate pivotally connected to the main floating body.
