Title: Food service system and method of rethermalizing food
Inventor: WIMPEE JULIA T
IPC: A47B31/02
Filed: 1990-08-06
Abstract: A heating system for use in a food service cart (12) includes a plurality of vertically spaced tray supports (30) attached to the cart (12) and a plurality of heaters attached to the cart at a plurality of vertically spaced locations in alignment with shelf locations for heating foods carried on service trays and supported by the tray supports. A thermostatic control controls the power supplied by each respective heater during a predetermined time period and includes a sensing mechanism for sensing temperature and a power adjusting mechanism for adjusting the power supplied by the heater. The sensing mechanism senses temperature over a predetermined range having upper and lower temperature limits, and the power adjusting mechanism reduces the power at which the heater operates to a lower power level when the sensing mechanism senses the upper temperature limit and increases the power at which the heater operates to a higher power level above the lower power level when the sensing mechanism senses temperature at or below the lower temperature limit. Food is rethermalized by a method that cotinuously applies power through a heater over the predetermined time period, alternately at the high and low power levels.

Title: Power amplifier for a cellular telephone
Inventor: KUNKEL L PETER
IPC: H04B1/04
Filed: 1992-08-07
Abstract: In a cellular telephone of the type capable of operating in both analog and digital modes, a power amplifier is provided which can operate efficiently in both the analog and digital modes of operation. The power amplifier includes a non-linear power amplifier stage and a linear power amplifier stage which are controlled by a switching means. During the analog mode of operation, the switching means causes the non-linear amplifier stage to amplify the RF signals. During the digital mode of operation, the non-linear amplifier amplifies the RF signal when there is a requirement for a relatively low power output. During the digital mode when there is a requirement for a relatively high level output, the switching means causes the non-linear power stage and the linear power stage to amplify the RF signals.

Title: Flow activated flowpath liner seal
Inventor: CARROLL MICHAEL D
IPC: F01D9/04
Filed: 1992-08-13
Abstract: A stator vane liner assembly includes seal keys supported in slots in the ends of vane liner segments in an engine casing, Stationary vanes supported in the liner segments for directing an engine airflow are urged against the keys by the engine airflow gas loads. The seal keys engage the ends of adjacent vane liners for sealing, and prevent further motion of the vanes with respect to the liner segments due to the engine airflow gas loads. Secondary seal means can be slidably captured between the seal key and vane liner segment to prevent axial and radial leakage around the seal key. The liner assembly reduces leakage of engine airflow and helps to isolate the engine casing from the thermal effects of leakage of engine airflow.

Abstract: A method of deeply desulfurizing a fossil fuel which contains a variety of organic sulfur compounds, some of which are labile to hydrodesulfurization (HDS) and some of which are refractory to HDS, comprising the steps of (a) subjecting the fossil fuel to HDS  or a similar method of desulfurizing labile organic sulfur compounds, and (b) subjecting the fossil fuel to biocatalytic desulfurization (BDS) using a biocatalyst which is capable of selectively liberating sulfur from HDS-refractory organic sulfur compounds. In this manner, a fossil fuel is produced which does not generate sufficient levels of hazardous, sulfur-containing combustion products that it requires post-combustion desulfurization when it is burned. Moreover, the deeply desulfurized fossil fuel can be produced using only a mild HDS treatment, rather than requiring conditions which may be severe enough to be detrimental to the fuel value of the desired product. The biocatalyst employed in the BDS  stage of the instant invention is capable of catalyzing the sulfur-specific, oxidative cleavage of organic carbon-sulfur bonds in sulfur-bearing aromatic heterocyclic molecules such as dibenzothiophene. A particularly preferred biocatalyst is a culture of Rhodococcus rhodocrous bacteria, ATCC No. 53968.
