Abstract: A tacker (1) with a power drive (3, 4) and a repeat-action control is provided. The repeat-action control comprises a device with a handle (33) for releasing a driving impact and with a feeler (15) which can be moved when the tacker (1) is applied to a workpiece. Connected to the feeler (15) is an impact repetition stop (59, 60) which forces the tacker to be lifted off from the workpiece before a new impact. This prevents operating faults resulting from the successive striking of fastenings, repeated impacts in the case of tackers being impossible without a new supply of fastenings. <IMAGE>

Abstract: The invention has a toothed rod (10) arranged axially displaceably in a steering gear housing (11), a toothed pinion (15) which can be driven by the steering wheel and actuates the toothed rod (10) and a pressure piece (20) which is supported in the steering gear housing (11) and acted upon by a spring, which pressure piece serves for generating a specific pressure force between toothed rod (10) and toothed pinion (15). Provided on one or more surfaces of the steering which are in frictional contact with one another during the steering process, are means, in each case only in the region corresponding to straight-ahead travel - which increase the coefficient of friction. By means of such means which increase the coefficient of friction at specific frictional points of the steering, which points are assigned to straight-ahead travel of the vehicle, a steering moment increase can be achieved in a simple manner in the centre region of the steering without geometric changes to the steering or an increase in the pressure force between toothed rod (10) and pinion (15) being required. The steering moment increase brought about by increased friction in the centre region of the steering compensates the known manifestations of wear occurring there after relatively long operation of the vehicle and avoids the sensations of danger, associated herewith, which the driver experiences. <IMAGE>

Abstract: In a sugar beet factory a rinsing stream frequently has to be pumped to a higher level either for reasons of space or to create potential energy. To do this pumps have in the past been used for hydraulic conveying but these were exposed to considerable wear and for this reason have not proved successful. The invention now proposes to use a bucket elevator 10 instead of pumps to raise the rinsing stream to a higher level. This is more reliable and resistant to wear, even wear caused by abrasive substances such as sand contained in the rinsing stream, particularly with a cantilever support for the (bottom) deflection sheaves 23. <IMAGE>

Abstract: Impact expansion dowels are known for insertion in undercut drilled holes in masonry, in which an expansion sleeve is pushed onto an expansion body supported on the base of the drilled hole when impacts are applied. The expansion region of the expansion sleeve in this case engages in the undercut of the drilled hole in a positively locking manner. In order that a tensile force applied to the expansion sleeve does not pull the expansion sleeve off the expansion body, the expansion body has a shank with a locking profile which engages into a corresponding locking profile of the inner hole of the expansion sleeve. In the region of the locking profile, the expansion sleeve is slotted and is thus designed to be elastic radially. <IMAGE>

Abstract: The invention provides a novel cleavage reagent for hydrolysing base-labile linking groups between a solid phase support and oligonucleotides. The cleavage reagent comprises a lower alkyl alcohol, water, and a non-nuccleophilic hindered alkylamine containing from 3 to 6 carbon atoms in a ratio of about 1:1:1 to about 1:3:1, respectively. An important property of the cleavage reagent is that it preserves the fluorescent characteristics of rhodamine dyes during cleavage, thereby making it possible to completely synthesize rhodamine-labeled oligonucleotides by solid phase methods. Rhodamine phosphoramidites are provided to further enhance the efficiency of synthesizing rhodamine-labeled oligonucleotides by such methods.
