A flexible auxiliary handle having an elongate member having a hand grip portion associated with a first end and an attaching portion associated with a second end wherein the elongate member provides for torsion or bending or both in response to motions and forces applied to the grip portion. The elongate member is typically advantageously comprised of one or more segments having characteristics enabling such action. The flexible handle ergonomically allows the gripping hand to move freely while the implement's tool maintains orientation to the ground without undue need for balancing, or for avoiding or performing certain undesirable movements customary with auxiliary handles. Such auxiliary handle is attractive, lightweight, cost effective to manufacture, has many configurations, conserves implement storage and retail space, installs and adjusts without tools, fits a wide variety of implements, enables conventional implement use, remains within easy grasp of the user, and is pleasurable to own.

A connecting assembly consisting of a hub and a plurality of U shaped connecting members for joining the framework of geodesic domes is provided. The hub is formed from a hollow member containing a plurality of radial grooves designed to accept the rectangular end of framing members. The rectangular ends are secured in the grooves by the U shaped connecting members that wrap around the bottom of the grooves of the internal side of the hub and thereafter lie adjacent to the flat end of the framing members. Further, nails, screws or bolts can be used to secure the U shape connecting members to the rectangular ends of the framing members. The frame members extend radially from the center of the hub and are so arranged that the angle between the adjacent framing members is at least 40.degree.. The grooves are so designed that the attached framing members form an angle from 1.degree. to 14.degree. with a plane perpendicular to the central axis of the hub.

Method and apparatus for electrical excitation of a laser gas by application of a pulsed voltage across the gas, followed by passage of a pulsed, high energy electron beam through the gas to initiate a discharge suitable for laser excitation. This method improves upon current power conditioning techniques and is especially useful for driving rare gas halide lasers at high repetition rates.

Electron beam switched discharge for rapidly pulsed lasers

An electron beam of energy typically 100 keV excites a fluorescer gas which emits ultraviolet radiation. This radiation excites and drives an adjacent laser gas by optical pumping or photolytic dissociation to produce high efficiency pulses. The invention described herein was made in the course of, or under, United States Energy Research and Development Administration Contract No. W-7405-Eng-48 with the University of California.
