Abstract: IMPROVED SEMI-FLEXIBLE DOUBLE-RIDGE WAVEGUIDE             ABSTRACT OF THE DISCLOSURE      A semi-flexible double-ridge waveguide comprises a corrugated tube formed into a special dumbbell-shaped cross-section defined by parameters which are conveniently optimized to realize improved power-handling capability as well as improved attenuation and VSWR factors across extended dominant-mode operational bandwidths.  The dumbbell-shaped cross-section efficiently removes the problems typically associated with the use of conventional rigid waveguide, including difficulty of installation as well as the need for precise alignment of components, by combining flexibility and ease of manufacture, even for long lengths of waveguide, through use of a continuous, uncomplicated and relatively inexpensive process.    The dumbbell-shaped cross-section is totally devoid of corners and other abrupt protrusions and is defined by a geometric equation in which specific parameters can be correlatively optimized to improve desired electrical properties of the waveguide.  The waveguide is rendered "semi-flexible" by the provision of helical corrugations having a staggered disposition of opposing corrugation crests and troughs, whereby the breakdown air gap and, consequently, the maximum power rating is increased.

Title: Set of x-ray film holders for taking x-ray exposures of an entire tooth
Inventor: KLAUSER ROLF M
IPC: G03B42/04
Filed: 1990-05-09
Abstract: Abstract of the Disclosure The set of X-ray film holders for taking X-ray exposures of an entire tooth consists of a holder for the side teeth and a holder for the front teeth, each of the holders comprising a resilient clip for the X-ray film, a formed bite portion and a cranked indi-cator rod extending perpendicularly to the film plane for adjusting the central X-ray beam orthogonally to the film plane.  The film clip is attached to the bite portion in such a manner that it is pivotable by 360° and may be locked in the plane which is formed by the indicator rod with its cranked portion.  Except for special X-ray tubes,  it is useful to have a centering aid for the central X-ray beam.   To this end, an index having pointer means is movably disposed on the indicator rod, guiding means being provided on the indicator rod and on the tube of the index in order to bring the pointer means into the correct position according to whether the X-ray film is in its upward or downward position.       Such a set of X-ray film holders enables exact aligning of all X-ray tubes with the currently used X-ray films for exposures of all teeth.
