Survivable pulse power space radiator
A thermal radiator system is described for use on an outer space vehicle, which must survive a long period of nonuse and then radiate large amounts of heat for a limited period of time. The radiator includes groups of radiator panels that are pivotally connected in tandem, so that they can be moved to deployed configuration wherein the panels lie largely coplanar, and to a stowed configuration wherein the panels lie in a stack to resist micrometerorite damage. The panels are mounted on a boom which separates a hot power source from a payload. While the panels are stowed, warm fluid passes through their arteries to keep them warm enough to maintain the coolant in a liquid state and avoid embrittlement of material. The panels can be stored in a largely cylindrical shell, with panels progressively further from the boom being of progressively shorter length. 5 figs.

Method and apparatus for the formation of a spheromak plasma
An inductive method and apparatus for forming detached spheromak plasma using a thin-walled metal toroidal ring are described that uses external current leads and internal poloidal and toroidal field coils located inside a vacuum chamber filled with low density hydrogen gas and an external axial field generating coil. The presence of a current in the poloidal field coils, and an externally generated axial field sets up the initial poloidal field configuration in which the field is strongest toward the major axis of the toroid. The internal toroidal-field-generating coil is then pulsed on, ionizing the gas and inducing poloidal current and toroidal magnetic field into the plasma region in the sleeve exterior to and adjacent to the ring and causing the plasma to expand away from the ring and toward the major axis. Next the current in the poloidal field coils in the ring is reversed. This induces toroidal current into the plasma and causes the poloidal magnetic field lines to reconnect. The reconnection continues until substantially all of the plasma is formed in a separated spheromak configuration held in equilibrium by the initial external field.

Groove refinishing tool
A groove refinishing tool is disclosed which utilizes a finishing wheel which is controlled by an air grinder motor. The air grinder motor is mounted on a main body section which is pivotally attached to a shoe element. The shoe element contains guide pins which guide the shoe element on the groove to be refinished. Application of pressure on the main body element compresses a weight counterbalance spring to extend the finishing wheel through the shoe element to refinish the groove surface. A window is provided for viewing the refinishing operation. Milling operations can also be performed by replacing the finishing wheel with a milling wheel.

Combination ring cavity and backward Raman waveguide amplifier
A combination regenerative ring and backward Raman waveguide amplifier and a combination regenerative ring oscillator and backward Raman waveguide amplifier which produce Raman amplification, pulse compression, and efficient energy extraction from the CO/sub 2/ laser pump signal for conversion into a Stokes radiation signal. The ring cavity configuration allows the CO/sub 2/ laser pump signal and Stokes signal to copropagate through the Raman waveguide amplifier. The backward Raman waveguide amplifier configuration extracts a major portion of the remaining energy from the CO/sub 2/ laser pump signal for conversion to Stokes radiation.

Anal Speculum.
Patent for a new and improved anal speculum. This design is "to so construct the several parts that there will be no rough or raised edges to interfere with its insertion in the anal passage; secondly, to so construct [the] improved speculum that it may be readily used as a bi-valve or dilator; thirdly, to form a locking-joint on the meeting edges of the shells forming the speculum, whereby the sections are prevented from overlapping each other to avoid pinching or injury to the walls of the anal passage while the instrument is being inserted; fourthly, to provide a plug for [the] improved speculum" (lines 17-29).
