Abstract: ABSTRACT OF THE DISCLOSURE   An improvement is provided in a syringe which is adapted to preclude reuse and which is prefilled with a drug solution.  The syringe has a hollow syringe barrel with an open distal end adapted to have a needle fixed thereto in fluid communication therewith for dispensing of the drug solution contained therein through the needle, the syringe having an open rear end adapted to be sealed by an elastomeric stopper in sliding engagement with the walls of the syringe barrel.  The improvement comprises a plunger assembly including a plunger-rod having a projection at one end, the projection comprising a reduced diameter portion terminating in a flanged tip.  The elastomeric stopper has a recess in one end thereof, the recess terminating in an enlarged flange-receiving portion.  The diameter of the flanged tip of the projection of the rod is less than the diameter of the flange-receiving portion of the recess of the stopper but is greater than the diameter of said recess of said stopper.  The interengaging surfaces of which are con-figured for releasably making engagement.  The functional relationship is such that (1)  the stopper is not released from the projection of the rod when limited manual withdrawal of the plunger is performed for a vein test prior to the administration of a solution of the drug to be administered due to a close approximation or equilibrium between the withdrawal force necessary to pull the piston back within the cylinder when taking the vein test and the blood pressure of a patient; and (ii)  the stopper is dis-connected from the rod, with the stopper remaining in the barrel, when, after the drug has been administered, the plunger is withdrawn within the barrel with a force equal to that necessary to aspirate a new solution into the syringe due to the friction between the plunger and the barrel being greater than the friction between the head of the piston rod and the mating recess in the plunger.  This renders the syringe useless for reuse.

Abstract: A METHOD AND AN APPARATUS FOR MANUFACTURE OF CYLINDRICAL ROTOR STRUCTURES FOR MOISTURE AND/OR HEAT EXCHANGERS.                Abstract of the Invention The invention relates to manufacture of a rotor mass for moisture and/or heat transferrers and composed of alter-nately plane and corrugated layers of thin sheet material with the corrugations forming axially extending fine channels. The layers are assembled in predetermined positions relative one another and joined together by gluing. As the glues hitherto used harden relatively slowly the layers, especially when consisting of very thin sheet material before solidifi-cation of the glue are exposed to displacement relative one another which may cause undesired deformations of the rotor and in particular the fine channels. To avoid this danger the invention suggests application of a second glue type in addition to the conventional glue type. Whereas the latter imparts to the rotor structure required mechanical strength, the additional glue is of a kind solidifying almost instant-aneously and thereby effecting a first direct sticking between the layers immediately upon assemblage and thus ensuring sufficient protection against displacement of the layers relative one another and deformation of the fine axial channels during subsequent assemblage, storage and transport of the rotor. The invention includes also an apparatus for carrying out the method in a simple and reliable manner.

Abstract: CURRENT SWITCH CIRCUIT HAVING AN ACTIVE LOAD                     ABSTRACT    An improved current switch circuit which has an active load is disclosed.  The active load comprises a current source at the collectors of switch transistors which generates a current which is less than the current generated by the current source at the emitters of the switch transistors.  The active load also includes a circuit for supplying the current difference between source cur-rents as a supplementary current to the current source at the emitters when the associated switch transistors are conductive and a circuit for diverting the source current at the collectors when the switch transistors are non-conduc-tive. Depending on the current generated by the current sources, the performance of the circuit can be selected to optimize power dissipation versus switching speed.  The circuit uses a minimum of resistors and a minimum amount of semiconductor area and thereby ensures low power dis-sipation.
