Abstract: A conference circuit in a digital telephone switching system includes a first code converter (CCL), which converts nonlinearly coded speech samples into linearly coded speech samples, and adder (ADD), which sums the converted speech samples originating from the participants in the conference, and a second code converter (LCC), which reconverts the sum values into nonlinearly coded speech samples. To avoid distortion without increasing the insertion loss, the speech samples of the individual participants are integrated with respect to time and compared in an evaluation circuit (EVC). The speech samples of the loudest participant are fed to the adder unattenuated, while those of all other participants are attenuated by a predetermined value before being added.

Abstract: In a process for producing wooden building components acted upon by flexural forces in the built-in condition, and made up of at least two members that are bonded together, the load capacity is increased by stressing at least one part of the component in the direction of its length by a linear force and is then bonded to another part of the component while still being acted upon by said force. In a preferred form of the invention at least one part of the component is acted upon by a pulling force and another part is acted upon by a compression force with a pre-stressing effect. The use of the process makes possible the production of bonded wooden structural members free of transverse forces.

Abstract: In a process for dyeing silicic acid glass fibres or textiles made from these fibres, with organic pigments, the glass is desized, if necessary, subjected to an acid treatment, dyed, and if necessary coated with a finish preferably impermeable to steam. The acid treatment is applied until an extraction yield of 2 % maximum, preferably 1 %, is attained and, after intermediate drying if necessary, the fibres are dyed with basic acrylic dyes having a K-value of  </=  3.5 and high stability to light in a pH range of 0 to 3 by a single-bath technique for mordants and dyes, if necessary with addition of wetting agents and complexing agents at a bath ratio of 1:4 to 1:15 and a temperature between ambient temperature and 130 DEG C. After dyeing, the fibres are rinsed, neutralized and subjected to further treatment in the usual manner or dried, mordanted at pH 0 to 3, and dyed at a pH corresponding to that of a 0.5 to 2 g/l aqueous solution of acetic acid. The invention also concerns the products so obtained.

Abstract: The binding of a nucleic acid probe with its complementary sequence in a targeted, single stranded nucleic acid is affected by the secondary and tertiary structure of the target nucleic acid. The rate and extent of hybridization of the probe with the targeted nucleic acid can be increased by the use of "helper" oligonucleotides. Helper oligonucleotides are selected to bind to the target nucleic acid and impose a different secondary and tertiary structure on the target to facilitate the binding of the probe to the target. The resulting hybrid of probe and target nucleic acid also exhibits a higher Tm than the hybrid which results from addition of the probe alone.

Abstract: The invention relates to a method, a device and a method for installing a cable in a tubular cable duct. In the method, the foremost end (3) of the cable (1) in the duct (10) and subsequent portions of the cable are first accelerated in a short time with continuous supply of further portions of cable from a torsion-free store. Then, from the instant a certain speed v is reached, the cable is maintained at a tension such that, at said speed and tension, centrifugal forces in bends and inwardly pulling components of tensioning forces in the cable compensate for one another at the position of said bends, the further portions of the cable being supplied at a supply speed such that the part of the cable already fed into the duct can continue to slide on the basis of its mass moment of inertia. The acceleration can be achieved by causing propelling forces to act on the cable upstream of the inlet end (10a) of the duct in conjunction with pulling forces which act at least on the foremost end (3) of the cable (1) in the duct. The magnitude of at least the propelling forces is controlled by adjusting to zero the net transverse force on the cable, in a bend (8; 51) in the cable located beyond the position where the propelling forces act upon the cable in the direction of movement of the cable. Advantages are that much higher installation speeds and/or greater installation lengths in one go are possible. <IMAGE>
