Patent DE-4125876-A1 (DE)
Title: Gas supply system for excimer laser - involves using crystalline noble gas-halogen cpd. as halogen source avoiding use of externally supplied gaseous components
Inventor: STREIT INGOLF
IPC: H01S3/036
Filed: 1991-08-05
Abstract: In a system for supplying an excimer laser with a laser gas comprising a halogen gas, a noble gas and a buffer gas, the laser has several gas entry openings, at least one entry opening ensuring laser gas introduction into the laser. The laser is connected to a piping network in which transport of the individual gas components in the pipelines is regulated by valves, one pipeline supplying the noble gas and the buffer gas and a vacuum pump being connected to the network. All the pipelines are solid connection pipes and/or plastic hoses and all the connections are gastight. The halogen gas supply pipeline of the network is connected to a container (5) filled with a crystalline cpd. of halogen and noble gas, pref. XeF2, XeF4 or KrF2. ADVANTAGE - The system avoids use of an externally supplied gaseous halogen component (thus improving safety e.g. in medical applications), provides simple and safe gas-filling of the laser, extends the lifetime of the gas-filling and ensures simple and safe operation of the laser.

Title: Pyrolysis treatment of hazardous waste in rotary furnace - involves using fuel gas obtd. by thermal treatment of raw materials with organic structure
IPC: F23G5/00
Filed: 1991-11-01
Abstract: Thermal control of rotating tube combustion units, involves producing controllable energy sources from any materials with an organic structure, e.g., hydrocarbon-contg. waste, esp. growable raw materials or other energy-contg. substances with an organic structure, a fuel gas, oily combustible condensates. More or less combustible residues are produced by a controlled thermal conversion, pref. by pyrolysis between 500-1000 deg.C, esp. 650-800 deg.C and these are worked up in closed circuits so that the individual streams of material after removal of useful substances are together used to enable a controlled, environmentally compatible rotary furnace combustion of low energy waste materials requiring supervision which are in themselves non-combustible, in order to provide optimum redn. in vol. and a sufficiently extensive mineralisation to allow environmentally compatible dumping of the residual material, whereby the gases evolved upon the pyrolysis of organic substances are subjected to a controlled rectification by quenching and multistage condensn. washing to give a fuel gas largely free from harmful substances, esp. free of organic harmful materials such as dibenzodioxines and dibenzofurans, which can be stored and is compressible with conventional units and has a heating value of 12500-34000 KJ/Nm3, esp. 16000-21000 KJ/Nm3, and this fuel gas is used pref. and burned to satisfy the heat requirement of the thermal decomposition, pref. for the indirect heating of the pyrolysis, and as supplementary energy for controlling the post combustion chamber temp. of the rotary furnace combustion. USE/ADVANTAGE - The process allows thermal treatment of a wide range of hazardous waste in rotary furnaces with minimal emission of environmentally harmful materials and reduced consumption of prim. energy sources. The thermal treatment can be combined with a recycling requirement to recover, e.g., metals, pyrolysis coke fractions, salts and organic condensate fractions for reprocessing. The process can be used, e.g., to treat hydrocarbon-contg. waste prods., plastics, circuit boards, contaminated oils, plasticisers, metal-laminated plastics packaging film, mixed waste from scrap automobiles, etc

Title: Unwinding awning with spring arms and ballast-pipe - has device opposing torque on winding shaft generated by extension movement
Inventor: WESSELS BERNHARD
IPC: E04F10/06
Filed: 1992-02-15
Abstract: The arms between the awning mounting and the ballast-pipe are spring-loaded in the extension direction.

The spring can be coupled directly between the mounting(4) and the shaft, or to the latter via a gear train, being wound up by the extension movement. Alternatively a linear spring can be used, acting on the shaft via a rope, belt or chain. The opposing torques exerted can have approximately the same characteristic curves. USE/ADVANTAGE - Easy winding and unwinding without affecting tautness of awning cloth.

Abstract: The insulator has an earthed casing with an insulator body supporting an HV electrode with a curved surface. The insulator body is made from partly homogeneous dielectric material and the casing is made from flanged tubular sections bolted together with a mounting ring. During operation of the plant, outside the insulator body, the electric field lines pass across the insulating gas from an electrode to the earthed casing. Within the insulator body, they pass from the electrode to the mounting ring. The insulator body may be made of two different homogeneous dielectric materials. ADVANTAGE - Avoids dielectric weak points irrespective of use to which insulator is put.

Inventor: BAUER BERND
IPC: C08J5/22
Filed: 1992-04-03
Abstract: The invention relates to a bipolar membrane comprising an anion-selective layer and a cation-selective layer, and to a process for the production thereof by producing a first ion-selective layer from the liquid phase and applying thereto a second ion-selective layer of opposite charge from the liquid phase. To this end, a first ion-selective layer is produced from a polymer solution L1 by spreading the solution L1 to form a film of a certain thickness, exposing the resultant polymer film, during the spreading, to an inert gas or gas mixture containing steam or saturated with steam, employing a gas or gas mixture having such a high content of steam that, on the one hand, condensation of the water is prevented and, on the other hand, the miscibility gap in the polymer/solvent/water phase diagram is reached, removing the solvent, and producing on the side of the resultant ion-selective layer which had been exposed to the steam-containing gas or gas mixture, a second ion-selective layer of opposite charge from a polymer solution L2.

Title: Measurement circuit representing measured frequency values - contains clock pulse generator, edge detector, gate circuit, digital filter and corrects for display equipment scatter
Inventor: ITO AKIO
IPC: G01R7/06
Filed: 1992-08-05
Abstract: A measurement circuit for use in representing measured frequency values converts the frequency of an input signal into a corresp. digital signal. A clock pulse signal is generated (303) at a higher pulse frequency than the input signal frequency. An edge detector (304) produces edge detection signals in synchronism with the clock pulses after sensing the input signal using the clock pulses. A gate (306) outputs a first factor signal when the edge detector senses an edge. A digital filter (308), connected to the gate and clock generator, produces a signal with digital values corresp. to the input signal frequencies and defined by the first factor whilst a cycle of the clock signal is used for time control of its sampling process. USE/ADVANTAGE - E.g. for vehicle speed indicator. Frequency measurement and display with simple correction of scatter or dispersion of display equipment.

Title: Large-area concrete slab for covering track installations
Inventor: GLAESER WOLFGANG DR
IPC: E01C9/06
Filed: 1993-02-04
Abstract: The invention relates to a large-area concrete slab for specialised covering of tramway tracks having grooved rails, preferably in the roadway situation. The object of the invention is to provide a precast-part covering which combines the advantages, in terms of dynamics of vehicle movement, of a uniform paving type in the entire road region with the desire bituminously to cover the track region as well. According to the invention, this is achieved in that a large-area slab, of the type which has been customary per se for a long time, is provided on the surface with a bituminous covering and wearing course (mastic asphalt). The longitudinal sides of the frame of the large-area slab serve as a template for the mastic-asphalt placement; in addition, they demarcate the mastic asphalt functionally from the rail and from the road surfacing. The longitudinal sides of the frame project, to this end, preferably 25 mm over the surface of the concrete base structure; at the transverse sides, the frame reaches only flush up to the surface of the concrete structure. The mastic-asphalt proportion of the entire slab thickness preferably amounts to 20 %.
