(Corresponding to U.S. Patent No. 3,354,3201

A system for determining the position of a light source about two axes of a reference position. The system, originally developed for orienting antenna on the Mariner spacecraft, utilizes a single movable part, a vibrating reed shutter, for alternately blocking and passing light from the source projected onto a photosensitive detector at the position of reference.

(Corresponding to U.S. Patent No. 3,459,391)

Expanded metal, that is, a thin metal strip which has first had short longitudinal cuts made therein and then been pulled transverse to the cuts to open the cuts into diamond shaped holes, has been used as interconnectors in a solar cell matrix to provide a flexible, somewhat resilient array. The solar cell array can be compactly stored prior to deployment and then deployed into a variety of shapes through the use of a new expandable frame in which telescoping tubes are extended to a desired length and then cemented to form a rigid support structure.

BALANCED BELLOWS SPIROMETER

NASA Case No. XAC-01547

Canada

Address inquiries to:
Ames Research Center
Attn: Patent Counsel
Mail Code: 200-11A
Moffett Field, CA 94035
U.S.A.

(Corresponding to U.S. Patent No. 3,420,225)

A laboratory instrument for measuring total lung capacity, vital capacity, maximum breathing capacity, tidal volume, functional residual capacity and oxygen uptake of human subjects. The spirometer, which employs two mechanically interconnected bellows, is compact, retains calibration, and is unaffected by acceleration fields along all three coordinate axes.

SPIN-STABILIZED SATELLITE

NASA Case No. XGS-02607

| Corresponding to U.S. Patent No. 3,341,151) A satellite, adapted to spin about an axis, having antenna elements for communicating with a remote body and a beam collimator rotatable with respect to the spin axis. The beam collimator is rotated at the same rate and in the opposite direction as the spin of the satellite to provide a directional beam stationary in space. Ejection apparatus enables the collimator to be jettisoned in event of rotational malfunction so that an omnidirectional beam may be provided about the spin axis. Signal processing circuitry operating in conjunction with the antenna elements provides information concerning the attitude of the satellite.

MAGNETOMOTIVE METAL WORKING DEVICE

NASA Case No. XMF-03793

Canada

Address inquiries to:
Marshall Space Flight Center
Attn: Patent Counsel
Mail Code: A&PS-PAT
Huntsville, AL 35812
U.S.A.

(Corresponding to U.S. Patent No. 3,360,972)

A portable magnetic hammer, a metal working device developed in the course of the Saturn program, wherein energy for manipulating a metal workpiece is acquired by creating a high-intensity magnetic field from a controlled electrical discharge into a conductor coil. This compact, lightweight device performs sizing, blanking, and stress removal functions without surface marring of the metals. It is expected that the magnetic hammer would find use in many environments particularly in removing dents, deformed or depressed surfaces from vehicles, fenders and bodies, tanks, etc.
