Abstract: An RF power amplifier including a splitter (62), two branch circuits, and a combiner (64). The splitter (62) has an input line receiving an RF signal (PIN), a first output line carrying a first output signal derived from the RF signal (PIN), and a second output line carrying a second output signal derived from the RF signal (PIN). A first branch circuit (60a, 74) receives the first output signal and generates therefrom a first derived signal. A second branch circuit (60b) receives the second output signal and generates therefrom a second derived signal therefrom. The first branch circuit includes a first power amplifier (60a) and a phase shifting element (74). The second branch circuit includes a second power amplifier (60b). The combiner (64), which has a first input receiving the first derived signal and a second input receiving the second derived signal, combines the first and second derived signals to produce a power output signal (PFWD) therefrom. The phase shifting element (74) is connected between the output line of the first power amplifier (60a) and the first input of the combiner (64) and produces a phase shift in a signal passing from the first power amplifier (60a) to the combiner (64) relative to a signal passing from the second power amplifier (60b) to the combiner (64). <IMAGE>

Abstract: A nitrogen doped single crystal silicon carbide boule is grown by the physical vapor transport process by introducing nitrogen gas into the growth furnace. During the growth process the pressure within the furnace is maintained at a constant value, Po, where Po</=100 Torr. This is accomplished by measuring the pressure within the furnace and providing the pressure measurement to a process controller which regulates the nitrogen introduction as nitrogen gas is incorporated into the crystal structure. The partial pressure of the nitrogen may be selected to be at a value between 1 and Po. If the desired partial pressure is less than Po, an inert gas is added to make up the difference.

Abstract: Electric toaster with a first heating element arranged at one side of a toasting compartment and a second heating element arranged at an opposed side of the toasting compartment. The first heating element is divided into two sub-elements. Two diodes and a switch provide the possibility to switch over from a normal two-sided toasting mode to an asymmetric single-sided toasting mode. In the normal mode the switch is closed and the sub-elements receive power only during different half-waves of the mains supply voltage, so that the effective radiant power of the sub-divided first element is equal to the radiant power of the second heating element. In the asymmetric mode the switch is opened and the resistance of the first heating element is greater than the resistance of the second element, as a consequence of which relatively more radiant power is emitted by the first heating element than by the second heating element.

Abstract: A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on the human skin surface. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The new natural repellent exhibits the longevity and repellency that is comparable to N,N-diethyl-m-toluamide (DEET), a synthetic compound employed in almost all commercial formulations, but the inventive natural repellent is more acceptable than DEET, which has an unpleasant odor and imparts a greasy feel to the skin. The inventive insect repellent, formulated in a volatile silicone fluid, was shown to repel and incapcitate stable flies. This finding demonstrated that repellency was not limited to mosquitoes, but extends to other biting flies or insects, thus demonstrating the utility of the novel insect repellent for protecting pets and livestock as well as humans.

Abstract: A safe, reliable SCR system for reducing NOx emissions from a lean-burn internal combustion engine utilizes urea in aqueous solution. Overheating and hydrolysis of the solution are prevented by maintaining the temperature of the urea solution sufficiently low that it is not permitted sufficient time at elevated temperature to hydrolyze the urea to such an extent that solids precipitate. In a preferred embodiment, an injector system similar to those used for fuel injection provides a constant feed to injectors and a return line. The feed and injection can be controlled to provide sufficient urea for NOx reduction and sufficient cooling capacity for the feed and injection system to avoid hydrolysis and deposits of hydrolysis products.

Abstract: An explosion vent (10) for covering an opening (12) in an enclosure (14) subject to the build-up of pressure is disclosed. The explosion vent includes a peripheral flange (16) configured for attachment to the enclosure around the opening, a pressure relief panel (18) positioned within and hingedly connected to the flange, and a plurality of connectors or rupture tab assemblies (19) connecting the unhinged portion of the pressure relief panel to the flange. The connectors break when the enclosure is subjected to pressure build-up for permitting the panel to shift outwardly from the enclosure for uncovering the opening in the enclosure. Rivets (72) are provided for attaching the rupture tab assemblies (19) to the pressure relief panel (18) which function to provide additional panel support and minimize localized bending of the rupture tabs (21) forming a part of assemblies (19) when the explosion vent is subjected to vacuum conditions, but do not interfere with rupture of the tabs and opening of the panel at a relatively low burst pressure. The pressure relief panel has a plurality of domed sections (46,48,50,52) presenting at least one valley defining bridge (54,56,58) therebetween. The domed sections and bridges cooperate to stiffen the panel so that it more uniformly distributes force on the connectors, causing all of the connectors to break at approximately the same time so that the panel more consistently opens at a selected burst pressure level.

Abstract: A method, which is used to make controlled defects corresponding to natural flaws and residual stresses in various kinds of test pieces. Defects identical to natural flaws are required to qualify non-destructive testing (NDT) procedures. In the method, sequential, repeated, heating-cooling cycles are used to create defects and residual stresses. The shape of the heating and cooling pattern, the duration of the heating and cooling, and the number of thermal cycles are used to control the size of the defects and residual stresses obtained. The defect is grown without initial flaw or other nucleator. The defects correspond to natural flaws in terms of morphology and also of the signals obtained with NDT methods, and are suitable for use in, for example, NDT-qualification blocks.
