Abstract: ABSTRACT                 STIMULATED EMISSION APPARATUS      Described is a high gain, soft x-ray pumped, inner-shell, photoionization amplifier/laser in Cd or Zn vapors (28).  The soft x-rays (40), generated by a laser-produced plasma or other high intensity x-ray source, preferentially remove inner-shell d-electrons from neutral atoms leaving them ionized in a 2D state and producing a population inversion with respect to a lower lying 2p state.  Also described are techniques for achieving inversions with respect to the ion ground state of Cd, Zn or Hg by optically pumping from the inner-shell ionized state to a higher energy level.  Iso-electronic scaling of Cd, Zn and Hg suggests similar lasing phenomena exist, for example, in Ga, In and Tl ions, respectively, and also higher iso-electronic sequences.

Abstract: Abstract of the Disclosure An intermediate connector assembly for establishing electrical connection between a header pin conductor and a remote female connector includes an outer insulating housing having slots defined in a wall, and a cavity adapted to receive a carrier.  The cavity includes an interior outer housing surface sloped toward the cavity in a direction of the slotted outer housing wall.  The carrier is movably received within the cavity, and carries at least one electrical terminal, the terminal having a male portion extending outwardly from the carrier and the outer housing, and a female portion disposed within the cavity of the outer insulating housing.  A wafer adapted to enclose the cavity of the outer housing carries at least one pin conductor for termination to the female terminal portion.  The wafer includes drive surfaces for contacting the carrier to force the carrier toward the conductor-receiving outer housing wall to an extent sufficient to establish electrical connection between the female terminal portion and the pin conductor.  The female portion, disposed within the cavity, is cammed onto the pin conductor to provide weak or zero insertion force termination.

Abstract: (Case No. 8222) ABSTRACT OF THE DISCLOSURE      A compact pneumatic brake unit having an output shaft arranged to operate transversely of a pneumatic service brake piston, with force amplification provided by a bellcrank member.  The pneumatic piston push rod is interconnected with a spring-actuated, air-released emergency/parking brake piston through a lost-motion connection, which provides for movement of the service brake piston independently of the emergency/ parking brake piston when the service brake piston is actuated, but which actuates the service brake piston jointly with the emergency/parking brake piston when the latter is actuated.          A slack adjuster mechanism is arranged on the output shaft to maintain the proper axial relationship between the service piston push rod and emergency/parking brake piston, whereby the emergency/parking brake spring force is maintained constant with brake shoe wear.

Abstract: MAGNETIC BASE MACHINE TOOL                ABSTRACT OF THE DISCLOSURE           A magnetic base drilling machine includes a base having a magnet coil therein and a motor assembly mounted on the base for driving a rotary cutting tool.  Electrical circuitry, including switches for applying power to the magnet coil, for reversing the direction of current to the magnet coil, and for controlling the current to the motor are provided for controlling the magnet coil and motor.  A user-manipulatable control handle includes a multi-function control cam having cam surfaces that selectively control the switch that applies power to the magnet coil and which physically blocks operation of the motor switch until the magnet coil is energized.  Conversely, the magnet coil cannot be de-energized until the motor switch is moved to its off position.  If desired, the direction of the electrical current applied to the magnet coil can be reversed to assist in removing the base from a magnetized work surface.  A pointed stabilizer pin is controlled by the control cam to mechanically engage and disengage a work surface as the magnet coil is energized and de-energized.

Abstract: BOOM EXTENSION STORAGE MEANS AND MECHANISMS     Abstract of the Disclosure A mobile crane comprises a multi-section telescopic main boom and a boom extension pivotally connected to the point end of the main boom.  The boom extension can be manually swung horizontally between an in-use position extending axially from the point end of the main boom and a stored position parallel to and alongside the main boom.  Front and rear boom extension storage mechanisms releasably secure the boom extension in stored position.  The front mechanism comprises two vertically spaced-apart storage pins which are slidable in tubular pin guides mounted on one lateral side of the main boom.  The storage pins are slidably movable fore and aft by a swingable lever to which they are pivotally connected.  The storage pins move into and out of engagement with a pair of vertically spaced-apart aligned pin-engaging holes in a member attached to a confronting side of the boom extension when the latter is in stored position.  The lever is not only pivotable but is axially shiftable into and out of latched positions and is biased into latched position to prevent unlatching due to "bounce".  The rear storage mechanism comprises a ramp on the side of the main boom which engages and supports a roller on a member attached to a confronting side of the boom extension and a removable pin secures the member to the ramp.
