Abstract: According to the present invention, a microwave generator includes a variable voltage provided from a first transformer to a second transformer having a secondary winding split into a filament winding cathode low AC signal and a secondary winding providing a high voltage which is doubled and rectified in a half-wave voltage doubler for providing a pulsed DC signal through a ballast resistor to a magnetron anode responsive to an electromagnetic field. In still further accord with the present invention, a microwave sample cavity includes a waveguide, and a hole for receiving a sample to be microwave-heated, and an inductive tuning post all on a straight line, wherein the hole is adjacent the waveguide and the post is distant from the waveguide.

Abstract: An inboard rudder 6 harbors within a bearing assembly 12 which passes vertically from a hull 10 of a boat 2 to a cockpit floor 8 of the boat 2 such that the inboard rudder 6 can be rotated around a vertical (z) axis 7 by a tiller 14 and raised or lowered by pulling or pushing on the top of rudder 6. Rudder 6 can be rotated about an axis (y) parallel to the width of the boat 2, in the fore and aft direction, by pulling or pushing on tiller 14 thereby altering a sweep angle 28 of the rudder (FIG. 3). Rudder 6 can be rotated about an axis (x) perpendicular to the length of the boat 2.

Abstract: A method and apparatus for dispatching elevator cars to hall calls in a system where there are two types of elevator controllers (12, 14) in operation, one (12) of which operates using relay logic. The calls are stored in a relay logic memory common to both elevator controllers (12, 14). A first controller reads the call information directly from the memory (18); the second controller reads the memory through a cross cancellation device (10) which multiplexes the information from the memory so that the calls are provided on a serial link (32) to the second controller (14). The second controller (14) is programmed to respond to calls which the first controller (12) has not answered.
