Abstract: A mateable pair of Ethernet connector assemblies for propagating data at Gigabit rates is disclosed. The pair of electrical connector assemblies includes a male Ethernet plug and a female Ethernet receptacle. The male Ethernet plug includes a substantially cylindrical hollow-body shell, an insulator body positioned within the shell, and a plurality of cylindrical pins positioned within respective apertures formed in the insulator body. One end of each pin extends beyond the mating surface of the insulator body for insertion into a respective socket of the female receptacle. The female Ethernet receptacle includes a substantially cylindrical hollow-body shell, an insulator body positioned within the receptacle shell, and a plurality of hollow-body cylindrical sockets positioned within respective apertures formed in the receptacle insulator body. One end of each socket is substantially flush with a mating surface of the receptacle insulator body for receiving a pin of the male Ethernet plug.

Abstract: A low pressure gas regulator which includes a ball valve which is surrounded by a soft rubber seat which has two different thicknesses with one of the thicknesses being greater in the region which contacts the valve seat and being thinner on the portion of the ball valve which does not engage the valve seat. The ball valve is connected to a valve stem which is connected to a moveable diaphragm which the controls the position of the valve in response to pressure variations.
