US Patent:

40317536, Jun 28, 1977

Filed:

Aug 20, 1976

Appl. No.:

5/716304

Inventors:

Richard G. Hooper - La Crescenta CA

Assignee:

The United States of America as represented by the Secretary of the Air
Force - Washington DC

International Classification:

G01N 100

US Classification:

73170R

Abstract:

An instrument for sampling both solid and liquid water particles in the atmosphere and continuously producing an electrical output response directly equivalent to the total percentage water content of the atmosphere sampled. The solid and/or liquid water particles are collected by using a large funnel shaped scoop of 100 cm. sup. 2 to allow high volume collection at nominal aircraft speeds. The water is routed into the detection device which includes a concentric cylinder flow-through capacitor that varies in capacitance according to the dielectric of the fluid enclosed.

Abstract:

A robot end effector includes a stationary plate having at least one stabbing pin extending therefrom and an ejector plate, adjacent to the stationary plate, having a at least one aperture through which the at least one stabbing pin extends. An actuator assembly comprising an actuator coupled to an ejector post via a linkage assembly advances and retracts the ejector post through a support, the ejector post extending through an aperture in the stationary plate and having a distal end coupled to the ejector plate. The ejector post increases separation of the ejector plate from the stationary plate when the ejector post is advanced through the support.
