Abstract: The radial press is for work with symmetrical outer faces, having a number of jaws (18) in a circle round the axis (A) of the outer surface and movable radially  in relation to it. The jaws have flat external control faces (19, 20) in a V-shape and inclined to this axis, and running between two parallel lateral guide faces on the jaws. The line bisecting the angle of the V extends in the radial direction, while the perpendiculars to the control faces passing through their centres of gravity intersect the axis. Control bodies (1,2) with faces (14,15) on the inside working against the jaw control faces are slid in relation to each other in the axial direction by a drive mechanism. The faces (14,15) are on two plates forming the bodies and which have radial grooves (12,13) of the same number as the jaws and whose sides (16,17) are parallel and guide the jaws. The bottom of each groove is smooth and at the same angles as the mating face on the jaw (19,20). The pairs of control faces are in a mirror-image pattern in relation to a radial plane (E) between the bodies, and there are plates (23,24) of bearing material between them.

Abstract: Described is a method for performing the amplification of nucleic acids by incubating in a vessel, in order to perform polymerization, a reaction mixture which contains in a suitable buffer solution one or several single-stranded target nucleic acids, suitable primers, deoxynucleoside triphosphates and a polymerase, whereafter the reaction mixture is transferred, by a procedure suitable in the given case, into another vessel for the denaturation of the nucleic acids, from which vessel, after denaturation, the reaction mixture is transferred back into the original vessel, by using a suitable procedure. The apparatus for performing this method includes one or several, preferably parallel, pairs of vessels. A vessel pair is made up of two vessels (1 and 2) which are interconnected or capable of being interconnected by means of one or several tubes (3). The apparatus may be provided with a separate heat exchanger (4) via which at least one of the tubes (3) passes, or a tube may as such serve as a heat exchanger. Each of the vessels is provided with a thermoregulator (11, 12), for example a heat block provided with a thermostat. Furthermore, the apparatus includes a fluid-transfer system (5-8, 10) for transferring the reaction fluid from one vessel to another. The vessel in which the polymerization occurs may be equipped with a suitable dosing device (9) for the adding of the polymerase and/or reagents. By using this apparatus it is possible fully automatically, without separate steps requiring an operator, to perform the amplification of nucleic acids on one or several samples simultaneously, under standardized reaction conditions.

Abstract: A system for subband coding of a digital audio signal x(k) includes in the coder (1) a filter bank (3) for splitting the audio signal band, with sampling rate reduction, into subbands (p = 1, ....P) of approximately critical bandwidth and in the decoder (2) a filter bank (5) for merging these subbands, with sampling rate increase. For each subband (p) the coder (1) comprises a detector (7(p)) for determining a parameter G(p;m) representative of the signal level in a block (p;m) of M samples of the subband signal xp(k) as well as a quantizer (8(p)) for adaptively block quantizing this subband signal in response to parameter G(p;m), and the decoder (2) comprises a dequantizer (9(p)) for adaptively block dequantizing the quantized subband signal sp(k)in response to parameter G(p;m). The quantizing characteristics are related to the noise-masking curve of the human auditory system, owing to which a high-quality of the replica x/< ANd >(k) of audio signal x(k) is attained with an average number of approximately 2.5 bits per sample for representing the output signals of the coder (1). The occasional audibility of quantizing noise in this replica x/< ANd >(k) is reduced effectively in that the coder (1) and decoder (2) contain identical bit allocation means (23, 24) responsive to a set of parameters G(p;m) for the higher group of subbands (pim</=p</=P) within an allocation window (Fig. 5) for allocating a number of B(p;m) bits per sample from a fixed predetermined number of B bits for this allocation window to the quantizer (8(p)) and the dequantizer (9(p)) for the block (p;m) of subband signal xp(k) and sp(k), respectively.

Abstract: The quantity of oil used as a heat transfer medium, is controlled continuously. It can be varied between minimum and maximum flowrates An Independent claim is included for corresponding equipment with a conventional cooling spiral (1) and pump (2) for the oil, and an electrical heating element. In the new design, a variable-speed motor (3) drives the pump and/or a proportional valve alters the quantity of oil through a cooling zone. Preferred features: A similar variant based on the foregoing method is claimed. Temperature of the circulating oil is held approximately constant by regulation of coolant quantity. The quantity of coolant for the oil used for heat transfer, is controlled as a function of oil temperature. The oil temperature is raised above the coolant temperature for the minimal flowrate during heating phases. The quantity of oil is varied by changing the speed of the pump drive, and/or by using a proportional valve. The cross section of the extruder cylinder in at least one of the heating zones, is approximately elliptical or oval.
