Abstract: A header connector apparatus (10) is configured to receive an electronic card (11). The apparatus (10) includes a body (12) having first and second spaced apart side arms (14, 16) formed integrally with the body (12) and configured to receive the card (11) therebetween. The first side arm (14) has a longitudinally extending first dovetail member (52). The apparatus (10) also includes an actuator button (48, 70) having a longitudinally extending second dovetail member (54, 74) configured to mate with the first dovetail member (52) to allow the button (48, 70) to move longitudinally relative to the body (12), and an ejector mechanism (36) coupled to the body (12) and the button (48, 70). The ejector mechanism (36) is configured to eject the card (11) from the body (12) upon longitudinal movement of the button (48, 70) relative to the body (12).

Abstract: This device projects slow moving light beams on the shadowed regions of a windowed room when the sun shines through the window. It includes a crystal-set (9) directly suspended from the bottom of a vertical rotor (14) of a motor (2) by a thread-like member (12). A small box (1), with attachment means to the window, supports the following interconnected electrical components: the motor (2) discussed above, a solar panel array (5), a capacitor (4), and a circuit (3). The capacitor is repeatedly charged slowly when the solar panel is exposed to sunlight, and discharged quickly by the circuit through the motor windings to occasionally pulse rotate the motor rotor about one turn. This occasional quick rotation activates and sustains the smooth and slow meandering rotation of the crystal-set about a vertical axis because of the loose thread-like member coupling between the motor rotor and crystal-set.

Abstract: An ion source which generates hydrogen ions having high atomic purity incorporates a solenoidal permanent magnets to increase the electron path length. In a sealed envelope, electrons emitted from a cathode traverse the magnetic field lines of a solenoid and a monocusp magnet between the cathode and a reflector at the monocusp. As electrons collide with gas, the molecular gas forms a plasma. An anode grazes the outer boundary of the plasma. Molecular ions and high energy electrons remain substantially on the cathode side of the cusp, but as the ions and electrons are scattered to the aperture side of the cusp, additional collisions create atomic ions. The increased electron path length allows for smaller diameters and lower operating pressures.
