Abstract: The novelty comprises a process for amplifying and detecting any target nucleic acid sequence (I) contd. in a nucleic acid or mixt. and for distinguishing between two different sequences in a nucleic acid. The process comprises treating separate complementary strands of the nucleic acid with a molar excess of two oligonucleotide primers, extending the primers to form complementary primer extension prods. which act as templates for synthesising (I), and detecting (I) so amplified. In an embodiment (also claimed), the synthesis of (I) is effected opt. in the presence of DMSO or at up to 45 deg.C, restriction enzymes are added for each of restriction sites present on the 5' end of the primers used, and after cleavage, the prod. is ligated into a cloning vector. The process may also be used (claimed) to synthesise a nucleic acid fragment from an existing nucleic acid fragment (II) having fewer nucleotides than the fragment being synthesised and two oligonucleotide primers. The prod. comprises a core segment, which is (II), and right and left segments representing the nucleotide sequence present in the 5' ends of the two primers, the 3' ends of which are complementary to the 3' ends of the single strands produced by sepg. the strands of (II).

Abstract: An agricultural spreader comprises distribution members (11, 12) which rotate to eject material such as fertilizer. The spreader can tilt to one side or the other so as to reduce the spreading distance on one side. This facility enables the spreader to be driven on a field along the same tracks as other agricultural machinery while avoiding waste of material at the edges of fields. Other embodiments utilize braking members which are movable into the path of ejected material to reduce its kinetic energy and consequently its spreading distance.

Granted: 1999-06-30
Abstract: A spacer for use in a disposable absorbent article. The spacer is symmetric about a longitudinal axis and has two transversely oriented springs generally orthogonal to the longitudinal axis. The transversely oriented springs have different spring rates, so that transverse compression caused by the wearer's thighs may be readily accommodated, yet the spacer remain open to receive fecal material. The spacer may be advantageously used in a disposable absorbent article having a void space between the topsheet and the core, and maintain this void space under the weight of the wearer.

Title: Improvements in the guiding and liquid treatment of threads
IPC: D01D10/04
Filed: 1943-01-04
Abstract: <PICT:0563296/IV/1> <PICT:0563296/IV/2> A device for guiding and supporting threads or filaments during treatment with liquids comprises a roller over which the thread is guided in a number of turns with progressive movement from one end to the other and upon which it is treated with liquids, and the roller is provided with one or more interrupted ribs or grooves for the purpose of confining each liquid treatment to a definite zone on the roller.  The device may be used in the manufacture of artificial silk threads or filaments which are treated with acid and then with wash water and finally dried. The gaps in the ribs or grooves facilitate the passage of the thread from one side to the other, particularly during the initial leading of the thread round the roller.  The ribs or grooves may be arranged in pairs and there may be more than one gap in each.  The ribs or grooves may be formed in the manufacture of the roller or ribs may be attached subsequently.  A split ring of springy material may be caused to grip the cylindrical roller by elastic contraction.  As shown in Fig. 1, two gapped flanges 1, 2 are provided on roller 3 with their gaps arranged in a line inclined to the axis of the roller.  The rib or ribs may be convex or prismatic in section and may be chamfered on one or both sides so that the thread is led smoothly through the gap.  As shown in Fig. 3, two ribs are provided with the gaps at opposite sides of the roller.  One rib may be placed at the end of the acid zone and the other may be placed two-thirds of the distance along the wash water zone.  The flanges may lie in a plane at right angles to the axis of the roller or they may be arranged helically.  To effect the forwarding of the thread, the latter may be passed around two rollers set askew relatively to one another, or around a pair of rollers and a bar.

Abstract: 1469391 Ultrasonic inspection devices COMMISSARIAT A L'ENERGIE ATOMIQUE 2 Jan 1975 [10 Jan 1974] 151/75 Heading G1G [Also in Division H4] A device for use in an ultrasonic inspection system for use in e.g. a liquid sodium environment in a fast nuclear reactor, comprises means for refracting the emitted or received wave from or to a focal point at the surface of an ultrasonic transducer at the interface of a 1st liquid medium e.g. tetrahydronapthalene and a 2nd liquid medium e.g. Nak which is contained in a tubular waveguide through which the acoustic waves pass as a parallel beam. Transducer E, fig. 2, is fed by cable 4 and is positioned a distance Z from transparent partition element D which as embodied, has its centre of curvature G in medium A such that Z#a<SP>2</SP>/# where a is the transducer radius and # is the wavelength in the medium A so that the Fraunhofer conditions prevail and a parallel beam 12 propagates through cylindrical waveguide T filled with medium B. The beam 12 is deflected by mirror 10 through spherical acoustic window D' to be focused e.g. on an object 9 within the medium C which is e.g. the sodium coolant of the reactor. The beam may be scanned and reflections 13 are detected by an identical unit 2. It is stated that the production of a parallel beam in the waveguide T improves ultrasonic transmission therethrough and that the separation of the transducer E from the Nak alloy B by tube T and inert medium A, reduces the possibility of radio-active contamination of the transducer. In a further embodiment (not shown) the waveguide and transducer are of rectangular cross-section and the partition element D is cylindrical, the axis of revolution of which being parallel to the greatest dimension of the transducer.

Abstract: 971,004. Moulding machines. R. W. TACCONE. Jan. 3, 1962 [Jan. 3, 1961; July 10, 1961; July 14, 1961], No. 292/62. Heading B3F. A device for compacting sand for casting moulds comprises a vertically sided flask 11 into which is telescopically located a pressure head 10. A membrane 17 of thick resilient materal (e.g. rubber) is clamped around its peripheral edges to the pressure head by a frame 18. The pressure head has a back-up plate 20 which positively engages the membrane 17 when the pressure head reaches its final compacting position. With the compacting force of the pressure head, air from cavity 21 passes into a cavity 22 within the head itself and is compressed, some air, as at 25 may be trapped between the membrane and pressure head. An inlet 26 in the head is provided to admit air into and out of the cavities as required. The movement of the pressure head into the flask effects a compacting action provided by two portions of the pressure head, a rigid area formed by the frame 18 and an elastic area formed by the membrane. The vertical pressure of the head in co-operation with the varying compressive actions of the two areas results in a uniform compacting of the sand throughout. Alternative embodiments include pressure heads with a number of separate or combined resilient members and also a balloon-shaped membrane within the pressure head which may be air pressure controlled.
