Abstract: PHOTOIMMUNE DETECTION OF DNA AND RNA      Abstract of the Invention A photoimmune method for detecting a particular polynucleotide sequence in a nucleic acid-containing sample is provided.  A single-stranded polynucleotide probe substan-tially complementary to the polynucleotide sequence to be detected is irradiated with ultraviolet light to induce formation of UV-photoproducts, principally pyrimidine dimers. The UV-labelled probe is contacted with denatured nucleic acid from the test sample under hybridizing conditions. Duplex formation is detected with anti-UV-nucleic acid antibodies which bind the irradiated probe. The antibodies are labelled with a signalling means.  A method for detect-ing/quantifying total DNA or RNA in a sample is also provided, as are kits for detecting particular nucleotide sequences, or for detecting total nucleic acid.

Abstract: Abstract:        A star coupler for optical fibres is suspended in a protection tube.  An optical fibre bundle is inserted into the tube, such as a hollow glass tube.  Then the bundle is twisted and stretched while it is indirectly heated through the tube, whereby to form a twisted, fused and stretched portion. Then both ends of the tube are sealed with an adhesive agent to fix the bundle in the tube.  This coupler can be constructed so as to be connected in tandem without any splicing.  The coupler can use multi-mode optical fibres or single-mode optical fibres.  It affords low insertion loss, reduced power deviation and a low manufacturing cost.

Abstract: ABSTRACT     A liquid sensor system particularly suitable for commercial washing machines for drinking glasses and soft drink dispensers employs a capacitive detector providing a tortuous path through which the liquid passes and constituting part of the dielectric of the resultant capacitor.  The pumps supplying the liquid through the capacitor to the dispensing means are controlled in accordance with the capacitance, as measured by a circuit.  A preferred measuring circuit comprises a pulse generator; one series of pulses split from the generator output is delayed by a fixed period and fed to a flip-flop, while the second series also from the generator output are delayed by a period dependent upon the sensor capacitance and are also fed to the flip-flop, the output of which is dependent upon which series of pulses is in advance of the other.  The circuit also provides for automatic adjustment of its sensitivity upon start-up or reset to adjust for differences in the sensors and the liquids.

Abstract: ABSTRACT OF THE DISCLOSURE         N-acetyl-D(L)-.alpha.-carboxylic acids are thermally racemized by melting them down, by adding a small amount of acetic anhydride to the melt and then heating them to a temperature being between the melting temperature and approximately 210°C until the race-mization is practically complete, whereupon the melt is chilled with an aqueous alkali metal hydroxide or ammonia solution.  The residence time required for the complete racemization depends on the heating temperature of the melt such that the higher the heating temperature the shorter will be the residence time.

Abstract: ABSTRACT      APPARATUS FOR COOLING A TUBULAR PLASTIC FILMS           Apparatus for cooling tubular plastic films extruded from a film blowing head comprises air cooling means consisting of co-axial pipes extending axially through the film blowing head to supply the cooling and inflating air and to withdraw the same from the inflated parison and vertically spaced apart inner cooling rings disposed substantially concentrically to the axis of the parison downstream of the annular extrusion die orifice of the blowing head.  The inner cooling rings together with annular members define nozzle gaps and have air guiding surfaces, which face the wall of the parison and are convexly curved in a longitudinal section of the inner cooling rings and during the operation of the apparatus are swept by the cooling air blown out of said nozzle gaps.  The cooling air blown out of said nozzle gaps flows approximately parallel or at an acute angle to the direction of travel of the parison.  Said cooling means also comprise outer cooling means, which concentrically surround the extruded parison and comprise an outer cooling ring defining an annular nozzle gap, which is adjacent to and downstream of the annular extrusion die orifice and serves to blow air in a direction which is approximately parallel to the direction of travel of the parison.  An apertured baffle plate or shield is provided, which surrounds the parison below its expanding portion adjacent to the downstream end of the cooling path defined by the inner cooling rings.  In an axial projection on the inflated parison, said baffle plate or shield covers at least the inner part of the inflated parison.  The baffle plate or shield has an annular inner edge, which together with the wall of the parison defines an annular gap.  The inner cooling rings concentrically surround the tube serving to withdraw the cooling and inflating air.  The inside diameter of the lowermost internal cooling ring is substantially as large as the diameter of the annular extrusion die orifice.  The diameters of the inner cooling rings above said lowermost inner cooling ring progressively decrease in an upward direction so that the parison will assume an upwardly tapering, frustoconical shape having a small included angle before it is inflated.

Abstract: LOW VOLTAGE RAILGUN ARC FORMATION     ABSTRACT OF THE DISCLOSURE     A low voltage plasma arc is first established across the rails behind the projectile by switching a low voltage high current source across the rails to establish a plasma arc by vaporizing a fuse mounted on the back of the projectile, maintaining the voltage across the rails below the railgun breakdown voltage to prevent arc formation ahead of the projectile.  After the plasma arc has been formed behind the projectile a discriminator switches the full energy bank across the rails to accelerate the projectile.  A gas gun injector may be utilized to inject a projectile into the breech of a railgun.  The invention permits the use of a gas gun or gun powder injector and an evacuated barrel with-out the risk of spurious arc formation in front of the projectile.

Abstract: ABSTRACT INDUCTIVE CIRCUIT ARRANGEMENTS A switched coil arrangement is connected in a bridge configuration of four switches S1, S2, S3 and S4 which are each shunted by diodes D1, D2, D3 and D4 so that current can flow in either direction through a coil L depending on the setting of the switches.  A capacitor C is connected across the bridge through a switch S5 to receive the inductive energy stored in coil L on breaking the current flow path through the coil.  The electro-static energy stored in capacitor C can then be used to supply current through the coil in the reverse direction either immediately or after a time delay.  Coil L may be a super-conductive coil.  Losses in the circuit can be made up by a trickle charge of capacitor C from a separate supply V2.
