Abstract: A connector especially useful as a power connector in electronic equipment has a housing adapted to receive any of several different types of contacts. One type of contact has a generally plainer, rectangular contact frame with integrally formed cantilever beams adapted to engage a mating contact and with integrally formed termination elements adapted to seat in vias of a circuit board. The connector provides a layer of resistance, cool-running reliable power connection which can be manufactured in a wide variety of styles at low cost. Male contacts having protruding contact beams also have contact frames which can be engaged in the housing.

Abstract: A system for extracting samples from a stream in a conduit utilizing a probe, placed in the stream and having a channel for passing samples from the conduit stream. First and second pressure taps measure the pressure inside and outside the probe. A feedback signal, based on a pressure differential relative to the probe, is generated and controls a valve regulating sample velocity flow through the probe channel, that bears a fixed proportion to the velocity of flow in the conduit. The constant of proportionality between flow velocities in the conduit and the probe may be 1.0, resulting in an isokinetic sampling condition.
