Abstract: Process for the recovery of fluorinated sulphonic acid catalyst from tar being formed during alkylation of hydrocarbons in the presence of the fluorinated sulphonic acid catalyst and containing spent fluorinated sulphonic acid catalyst in form of salts with basic components in the tar, which process comprises, 
   treating the tar with a proton donating acid by mixing of the acid and the tar, thereby, converting the spent catalyst to the fluorinated sulphonic acid; 
   separating the obtained fluorinated sulphonic acid from the tar-acid mixture by stripping off the acid from the mixture with an inert stripping agent at a temperature of 0-200 o C and pressure of 0.001-1 atm; and finally 
   recovering the separated fluorinated sulphonic acid from the stripping agent.

Abstract: The invention concerns welding of metal (esp. galvanised steel), sheets (1, 2), according to which clamping forces are applied by means of an accompanying clamping element (5), to the sheets in the immediate vicinity of welding spot of the laser beam used for joining these sheets. The focus (4) of the laser beam is preceded by directed deformation of the top sheet (1) until it makes line contact with the bottom sheet (2) for subsequent welding. An oscillatable piezoelement (8) is located between the clamping unit (6) and the clamping element (5) for producing an intermittent pressure on the latter during the clamping process. The directed deformation of the top sheet with plastic and elastic constituents is used to reduce the gap between the sheets. The intermittent line contact between sheets produced by the oscillating piezoelement leaves side pockets for escaping gas. The stroke of the piezoelement (8) is about 0.3 mm, while the forces exerted by it lie within the kN range. <IMAGE>

Abstract: The invention relates to a method for the better utilisation of the working width of a profiling block (1) in the inner profiling of heat exchanger tubes (5). The width of contact (7) of the revolving rolling elements (6) is significantly less than the profiled width of the profiling block, with the result that the profiling block wears rapidly in this region while the remaining region remains unworn and therefore unused. In order to avoid this, the invention proposes that the contact-pressure rollers and the profiling block should be moved backwards and forwards axially within the range of the working width of the profiling block, thereby allowing the entire profiling region of the profiling block to be used. <IMAGE>

Abstract: The vehicle roof folds into a compact storage behind the rear seat and occupies the forward part of the rear luggage space. A movable wall (6) separates the folded roof from the luggage. When the roof is erected the additional luggage space is available after the wall has been removed. A simple fitting for the wall has it hinged about a transverse axis. The wall either hinges down onto the floor of the luggage space or hinges about its top edge to swing up to cover the space between the normal boot lid and the rear seat. Interlocks prevent the roof from being folded while the wall is in the wrong position.

Abstract: A surveillance information recording system comprises a recording device loaded with a recording medium for recording video information concerning the object or place to be monitored, and a dummy device which can eject a recording medium in a manner similar to that in which a recording medium is ejected from an ordinary recording device. The recording device is located in an inconspicuous place, or concealed. The dummy device is located in a relatively conspicuous place. An intruder will mistakenly believe that if he carries out an ejecting operation on the dummy device and takes away the ejected recording medium, no evidence against him will be left behind. As an alternative, two loading sections may be provided in a single recording device, the recording of information being carried out in one of the loading sections, and the recording medium in the other loading section being ejected responsive to an ejecting operation.
