Abstract: The invention provides a method and system for providing unique ATM End System Addresses, in which each new device is assigned a unique address in an ATM network while allowing all new devices performing the PNNI protocol in a selected set (such as all those from a single manufacturer) to be assigned by default to the same peer group.

Abstract: There is described a single use disposable hypodermic syringe and a manner for its manufacture. The syringe has a polystyrene barrel and a plunger assembly snuggly mounted for reciprocation therein. A plunger movement-limiting means is provided and comprises a first ratchet-like track section extending longitudinally of the barrel on its inside wall, a second ratchet-like track section parallel to and spaced from the first track section and oriented in a direction opposite to the first track, and a cross-over ratchet-like track section connecting the first and second track sections, and track engaging click means on the plunger assembly. The plunger assembly may be, moved outwardly of the barrel unidirectionally along the first track section to perform a syringe priming stroke; relocated within the barrel unidirectionally along the cross-over track section to the second track; and moved inwardly of the barrel unidirectionally along the second track section, to perform a delivery stroke.

Abstract: There is described a single use disposable hypodermic syringe which has a hollow cylindrical body closed at its front end and open at its rear end. A hypodermic needle is mounted in the closed end of the barrel eccentrically of the longitudinal axis thereof. Inside the barrel there is an inwardly directed lip extending around the inner circumference of the barrel and spaced from the closed end of the barrel and forming with the closed end, a pocket. A plunger is housed in the barrel and is freely reciprocal therein outside the pocket. The plunger has a resilient piston made of a medical rubber compound at its leading end and a plunger rod extends rearwardly of the piston through, and beyond, the end of the barrel and terminates in a flange to which thumb pressure is applied when administering medication with the syringe. The plunger piston is attached to the plunger rod by means of a breakable connection.
