Abstract: ABSTRACT         There is disclosed herein an antenna for generating a rotating pattern.  The pattern is generated electronically, and no physically moving parts are required.  An exemplary embodiment of the antenna radiates a cardi-oid pattern which rotates at a 15Hz rate for use as a Tacan beacon.  The structure of the antenna is in the form of a conic monopole above a ground plane.  A plurality of vertical modulator fins, providing controllable short-ing elements, and a plurality of suppressor posts are added.  The modulator fins have associated diodes to which are applied a bias current along with modulating signals which cause the resistance of the diodes to vary with respect to the flow of RF current at the frequencies of interest (such as in the neighborhood of 1 GHz for Tacan usage).  Other details of the physical structure of the antenna are shown and described herein, as well as an elec-tronic system for controlling the diodes.  In a typical application, the antenna is mounted on an airplane to enable the airplane to serve as a beacon. In this instance, the exemplary system as shown and described herein is adapt-ed to be coupled with the synchro system of the airplane compass for provid-ing a reference with respect to magnetic north so as to properly electronical-ly relate the rotating pattern of the antenna to magnetic north while the airplane upon which the antenna is mounted changes its flight direction.

Abstract: FIELD REPLACEABLE MODULES FOR      INK JET HEAD ASSEMBLY                     Abstract The ink jet head assembly disclosed herein has modular subassemblies with predetermined relation-ships between the subassemblies to minimize realign-ment of the ink stream when a subassembly is replaced in the field.  The head assembly is modularized into nozzle, charge electrode, deflection electrode and gutter subassemblies.  The charge electrode module is mounted on the nozzle module in a manner such that no field adjustment is necessary to center the charge electrode horizontally to the ink stream. The deflection electrode module is mounted on the gutter module in a manner such that no field adjust-ment is necessary to center the deflection electrode horizontally to the ink stream.  The nozzle and charge electrode subassembly have a preset adjust-ment, and the gutter and deflection electrode assembly have a preset adjustment such that no field adjust-ment between these two subassemblies is necessary to maintain a constant flight distance for the ink drops. Finally, the nozzle module is adjustable to reposition the ink stream about the pitch axis (vertical adjustment) and the yaw axis (horizontal adjustment).  The yaw axis adjustment may be preset. The pitch axis adjustment is the only mechanical adjustment necessary in the field when replacing the nozzle module.

Abstract: ABSTRACT:            The invention is concerned with a method and an apparatus for the vaporization of liquid in a heat exchanger of the vertical-tube type, in which exchanger the vapour or liquid delivering the heat is passed through the tubes of the group (7) of tubes in the heat exchanger prefer-ably from the bottom upwards.  The group (7) of tubes is passed through at least one nozzle plate (18) or nozzle basin (22) so that nozzle openings (16, 20, 23) surrounding the tubes are formed between the openings in the nozzle plates and the tubes.  In the heat exchanger the liquid to be vaporized is passed to the mantle side into the upper part of the heat exchanger or into each nozzle basin of the heat exchanger separately and is guided so as to flow downwards on the outer face of the group (7) of tubes as a liquid film.  The vapour develo-ped from the liquid film is, by means of vapour flow passages formed into the group (7) of tubes, passed from the lower part of the heat exchanger further into its object of use or from each component unit (1, 2, 3) of the heat exchanger further into its object of use.
