| 20090009390 | DUAL BAND QUADPACK TRANSMIT/RECEIVE MODULE - A multi-channel, dual-band, radio frequency (RF) transmit/receive (T/R) module, for an active electronically scanned array, is provided. The module includes a compact, RF manifold connector and at least four T/R channels. Each of the T/R channels includes a notch radiator, a diplexer coupled to the notch radiator, a power amplifier, including at least one dual-band gain stage, coupled to the notch radiator, a low noise amplifier, including at least one lower-band gain stage and at least one upper-band gain stage, coupled to the diplexer, and a T/R cell, including a phase shifter, a signal attenuator and at least one dual-band gain stage, coupled to the power amplifier, the low noise amplifier and the manifold connector. | 01-08-2009 |

| 20100061180 | EFFICIENT WET STARCH PREPARATION SYSTEM FOR GYPSUM BOARD PRODUCTION - The present invention provides a wet starch preparation system for gypsum wallboard comprising a loss-in-weight starch feeder, a venturi mixer, a vacuum pick-up unit for supplying the dry starch from the feeder at an adjustable rate to the venturi mixer, a first water pump for supplying water at an adjustable rate to the venturi mixer to form a starch pre-dispersion of from about 2% to about 10% by weight starch and a second water pump for supplying gauging water to the starch pre-dispersion, the system equipped with appropriate system controls. The present system provides more efficient use of starch such that the amount of pregelatinized starch is at least about 10% less than a system in which the starch is not pre-dispersed in water prior to the board mixer. The system can be used to make gypsum-containing products including gypsum wallboard having increased board strength and reduced board weight. | 03-11-2010 |
