Abstract: An exhaust system of an internal combustion engine includes a slip joint with a female section having an opening with an inner diameter, a male section having an outer diameter smaller than the inner diameter of the opening of the female section, the male section being at least partially received in the female section, a wear sleeve disposed between the female section and the male section, and at least one seal contacting the wear sleeve and at least one of the female section and the male section, to seal the slip joint.

Abstract: An ion exchange membrane fuel cell is described and which includes a module enclosing a membrane electrode diffusion assembly which has an active area defined by a surface area, and which produces an average current density of at least about 350 mA per square centimeter of surface area when supplied with a dilute fuel at a nominal voltage of about 0.5 volts.

Abstract: An improvement for effecting rapid warm-up of the thermionic cathode means in a color CRT display device utilizing a degaussing circuit including a temperature responsive resistive element in series with the primary winding of an inductive means. A direct operational relationship is established between the degaussing and cathode heater circuits by having the secondary winding of the inductor series coupled therein. Upon simultaneous activation of both circuits, through a common switching means, a transitory surge of current is supplied by the degaussing circuit to the heater circuit, via the common inductor, to effect an accelerated temperature response in the heater.
