Title: System for identifying objects and persons and for transmitting information
Inventor: VOGEL KLAUS DIPL ING
IPC: G08G1/017
Filed: 1981-07-15
Abstract: A system of this type comprises a read device (LG) and an information medium (identification arrangement KA) with a multiplicity of transit time branches which is provided on the object which is to be identified or at the information storage location. Electromagnetic read signals arriving from the read device (LG) with a multiplicity of echoes representing the information content are radiated back by the information medium (KA) via a radio field (F) to the read device (LG), in which they are evaluated. Transit time changes caused by temperature changes in the identification arrangement (KA) are intended to be compensated. For this purpose, the invention provides that two adjacent transit time paths with attenuation components ( pi R,  pi T) are used, of which the component of one transit time path forms a reference component ( pi R) while the component of the other transit time path is an attenuation component ( pi T). The change in the transit times of the individual bits which occurs in the event of temperature changes in the identification arrangement (KA) and which is proportional to its transit time length is compensated in the read device (LG) by a proportionally identical change in the clock frequency of a time window switch (12). <IMAGE>

Title: Process for the production of doped SiO2 glass
Inventor: SUTO SHOICHI
IPC: C03C13/00
Filed: 1981-09-14
Abstract: In order to produce doped SiO2 glass for glass fibres, quartz powder or fine particles of SiO2 glass are treated with a gas containing SiCl4, a gaseous additive and steam in order to add the dopant to the glass element. This glass element is melted at high temperature to produce transparent, doped SiO2 glass. The production of the glass particles, the addition of the dopant and the vitrification of the glass element are carried out in separate process steps, in each case under suitable conditions. The production rate is significantly increased due to the individual process steps. The dopant content is unlimited and can be adjusted to any desired value by changing the reaction time during dissolution. It is also possible to add dopants such as PbO2, SnO2 and ZnO which are otherwise extremely difficult to employ to the glass element. In order to produce the glass fibre preform, the doped SiO2 glass is precipitated and melted on a starting material which is tilted at an angle of from 5 to 90 DEG with respect to the beam direction of the doped SiO2 glass. This gives a transparent, doped SiO2 glass element of uniform external diameter and uniform boundary surface at a high synthesis rate. This enables the mass production of glass fibres at low cost. <IMAGE>

Title: Profile strips or the like having a profiled differently-coloured visible region
Inventor: MAYER GERT
IPC: B60R13/04
Filed: 1981-09-17
Abstract: The invention relates to a pressure filter for separating off residues from the wet ashing of Pu-containing wastes in a housing having a cover and a feed for the wastes, in which a separation of the wastes and the filtrate is carried out. The object underlying the invention is to design a pressure filter of this type in such a way that with it a rapid filtration can be carried out even under room temperature conditions without moving parts. This is achieved by a filter pot being arranged in the housing, into which filter pot a screen basket can be water-tightly inserted in such a way that, between the screen-like baseplate of the screen basket and the bottom of the filter pot, a collection space for the filtrate results, which can be conducted away via a filtrate outlet connection piece water-tightly through the bottom of the housing by pressurising the housing interior or generating a reduced pressure at the filtrate outlet connection piece. The particular advantages of the invention are that the filter cake is produced on a screen basket which can be rapidly and simply inserted and the separation of pressure zone and outlet zone is performed by a seal, having an axial effect, on the underneath of the screen basket. Furthermore, the compression pressure for the seal is effected by the operating pressure via the filter surface in the screen basket. Mechanical precompression proves to be unnecessary, but could be provided in the filter.
