Patent DE-4314693-A1 (DE)
Inventor: EHLE FRIEDHELM
IPC: B08B9/02
Filed: 1993-05-04
Abstract: An apparatus (1) for cleaning lines (2), for example ducts, pipes or sewer ducts, which has an end-side inlet or a shaft or access location arranged laterally with respect to its line of progression, has a flushing head (3) and a feed line (4) to said flushing head (3), it being possible to introduce cleaning fluid or cleaning water at high pressure into the line to be cleaned, to be precise expediently from that side of the flushing head which is connected to the feed line (4) thereof. The apparatus (1) further exhibits a suction pipe (5) which is fixed in the pipe or duct to be cleaned and takes in the fluid, discharged by the flushing head (3), and the particles of dirt received therefrom and delivers them to a cleaning vehicle. In order, in this arrangement, to prevent flushing water or freed gases and vapours from being able to pass through between suction pipe and wall of the line (2) to be cleaned, the suction pipe (5) has an exterior seal (7) which can be pressed against the wall of the line (2) and can preferably be widened in order to carry out this press-on action. <IMAGE>

Patent DE-4321114-A1 (DE)
Title: Steering device for a bicycle
Inventor: BECK HUBERT
IPC: B62K21/14
Filed: 1993-06-25
Abstract: The invention relates to a steering device (1) for a bicycle with a handlebar stem (2) which can be connected by clamping to an extension tube of a bicycle fork of the bicycle, and with a handlebar support (5) which is arranged in an articulated manner on said stem and has, on its end opposite the joint (8), a clamping device (6) for attachment of handlebars. The proposal is for a spring element (10) which is connected in such a manner via an articulated bracket (4) to the handlebar support (5) that, within a spring deflection limited by stops, spring-mounting with simultaneous damping (shock-absorption) is possible. The advantages of this arrangement lie in the configuration of the spring element (10) which does not result in any changes with respect to the assembly ratios, unlike conventional handlebar attachments to front-ends. Furthermore of advantage is the fact that with the proposed spring element (10), by means of slight modifications, all of the requirements for the need of the handlebars to be spring-mounted can be fulfilled. <IMAGE>

Title: Process for setting up basins for sewage treatment
Inventor: LOSERIES HANS-GEORG
IPC: B01D21/00
Filed: 1993-06-29
Abstract: Tanks and basins which are to be installed underground, e.g. for collecting, storing, treating or monitoring sewage and the like are produced from reinforced concrete. The inner surfaces which come into contact with the hazardous sewage contents have to be coated in order to render them impermeable and resistant. For the production of such tanks or basins on site, it is proposed to form the inner coating as an inner-shuttering hollow body which is prefabricated in the factory, to fit the reinforcement around said hollow body and to introduce the concrete into the outer shuttering erected thereafter. All that need then be transported to the site of installation is the reinforcement and the hollow body which may, in some circumstances, still be in the subdivided state. Inlet fittings and other directional fittings already form a constituent part of the prefabricated inner-shuttering hollow body.

Inventor: STOELZLE ANTON DR ING
IPC: G10L15/12
Filed: 1994-05-19
Abstract: The invention relates to a voice recognition system operating in the following manner: In a training phase, reference voice signals corresponding to the voice signals to be recognised are processed as follows: From the reference voice signal available for processing are obtained first characteristic vectors which are then subjected to vector quantification in which the individual vectors are compared with a plurality of cluster vectors having an address and stored in a code book and a first cluster vector is found which corresponds most closely to the characteristic vector concerned in relation to a predetermined latitude. The address of the first cluster vector found is then stored in an address store. In the recognition phase the voice signals to be recognised are processed as follows: Two characteristic vectors are obtained from the voice signals available for processing and then subjected to classification in which the individual vectors are compared with the first cluster vectors characterised by the addresses in the address store. By means of the comparison, that reference voice signal is identified as the voice signal to be recognised, the cluster vectors of which correspond most closely to the second characteristic vectors in relation to the latitude.
