Abstract: A passive needle guard includes a body having proximal and distal ends and a cavity therein for receiving a medicine cartridge, and a shield slidable on the body between retracted and extended positions for exposing and covering, respectively, a needle extending from the body, the shield being biased towards the extended position. Deflectable latch members extend from the shield that include catches for engaging catches on the body for holding the shield in the retracted position. A syringe is inserted into the needle guard, and a needle of the syringe inserted into a patient. A plunger of the syringe is depressed to inject medication and to deflect the latch members to disengage the catches and release the shield, whereupon the shield automatically advances to the extended position. In the extended position, cooperating detents on the shield and body engage one another, thereby preventing subsequent retraction of the shield.

Abstract: The present invention provides a process for detecting the presence or absence of at least one specific nucleic acid sequence in a sample or distinguishing between two different nucleic acid sequences in said sample, wherein each nucleic acid sequence to be detected consists of two separate strands, which process comprises amplifying the specific sequence or sequences (if present) by   (a) treating the sample with one oligonucleotide primer for each of the two strands of each different specific nucleic acid sequence being detected under hybridizing conditions such that for each strand of each different sequence being detected an extension product of each primer is synthesized which is complementary to each nucleic acid strand, wherein said primers are selected so as to be substantially complementary to each strand of each specific sequence such that the extension product synthesized from one primer, when it is separated from its complement, serves as a template for synthesis of an extension product of the other primer; (b) treating the product of step (a) under denaturing conditions to separate the primer extension products from their templates; (c) treating the product of step (b) with oligonucleotide primers such that a primer extension product is synthesized using each of the single strands produced in step (b) as a template; and detecting the thus amplified sequence or sequences (if present).

IPC: G01R19/20

Abstract: For the measurement of large currents, d.c. as well as a.c., a so called zero-flux current transformer may be used. It comprises two identically wound toroidal cores (11,12), in which the magnetic flux induced by a main or primary current (I1) is neutralized by a counter-flux induced by a compensation current (I2), which by means of an amplifier circuit (40) is passed through a compensation winding (14) common for both cores (11,12) and having many turns. The compensation current (I2) is adjusted by means of the amplifier (40) to such a value, that the mean flux in the cores (11,12) is zero. The intensity of the compensation current (I2) is measured by the voltage drop across a measuring resistor (15). Any unbalances between the primary and secondary ampere-turns are sensed by a detecting circuit comprising a sensing winding (21,22) wound on each core (11,12) and divided into two subwindings which carries a magnetizing current (I3) from a current source (23) in such a way, that the odd-harmonic components contained in the magnetizing current are outbalanced, whilst the even-harmonic components contained therein are added and conducted to a synchronous rectifier (32) to provide a control signal to the amplifier (40) for the adjusting of the compensation current (I2). 
<??>Hereby is obtained a largely improved signal-to-noise ratio for the signal applied to the synchronous rectifier (32), and the need for a complex and expensive active 2nd-harmonic filter is eliminated.
