A drive system for a twistable septum in a feedhorn for use in satellite communications antenna systems. The drive system includes a flexible drive rod, coupled to a drive motor, which bends to accommodate off-center coupling with the septum drive wheel.

Drive system and filament for a twistable septum in a feedhorn

Feedhorn for parabolic antennae

A reflector for high gain antennae comprising a plurality of generally triangular shaped petals joined in edgewise overlapping relation, wherein the overlap gradually increases from rim to center of the reflector, so as to provide a mechanically stable paraboloid configuration. The petals are supported by a rigid rim structure constructed of preformed tubular sections.

Parabolic reflector

A non-impact printing system in which a multi-wire head collects debris has an arrangement for cleaning the head with a brush by sweeping the head over the brush in a first direction and immediately sweeping the head back over the brush in the reverse direction, while simultaneously pulling the head away from the brush. Certain aspects of the preferred embodiment disclosed herein include inventive subject matter set forth in the copending application of Robert Burdett Taggart, Ser. No. 26,647, filed Apr. 3, 1979, entitled, 'Printing Apparatus Drive System'.

Head cleaning apparatus for electroresistive printer

Dish reflectors with high gain antennae comprising a plurality of generally triangular shaped petals joined in edgewise overlapping or abutting relation so as to form a substantially paraboloid configuration. Petal configuration is controlled by fastener holes positioned to bend the petal in a substantially parabolic manner along its longitudinal axis and in a substantially curvilinear manner along its transverse axis.
