Abstract: This invention is a barbecue type grill that can be used either indoors or outdoors.  By disposing a convertible drip pan that can be opened and closed between the food supporting  rack  and  the  cooking  heat  source,   rapid preheating can be accomplished as well as searing of desired food products,  followed by  closing of  the  drip pan  to prevent unwanted flare-ups caused by juices dripping from the food being cooked.  This closing of the drip pan allows the food to cook slower than over direct heat which allows the food to retain more juices when done.   This invention overcomes  the  slow  preheating  and  slow initial  cooking inherent in the prior art using a solid impervious drip pan.         Also, since different types of heat sources can be used in conjunction with the present invention, the problem of the bottom of the housing rusting out in  the area adjacent the round burner below the heat deflecting plate is effectively eliminated.

Abstract: A system for performing high resolution measurement of frequency variations in multimode fiber laser acoustic sensors having an end-pumped active fiber sensor emitting a plurality of lasing modes, wherein precise frequencies of the lasing modes emitted are dependent upon a strain acting on said acoustic sensor. An optical fiber is connected to the active fiber sensor for transmitting the lasing modes. The optical fiber transmits the multiple lasing modes to an optical amplifier fiber where the lasing mode signals are amplified. The amplified lasing modes signals are then fed through a phase modulator connected to the optical fiber for applying a phase generated carrier on the lasing mode signals. The output from the phase modulator is supplied to a receiving interferometer having a predetermined path imbalance for interferometrically analyzing the frequency shifts of each of the lasing mode signals, wherein the predetermined path imbalance is matched with the longitudinal mode spacing between the lasing modes of the active fiber sensor. A demodulation unit is connected to the receiving interferometer for receiving and demodulating the output of the receiving interferometer to determine the frequency shift incurred by the lasing mode signals, wherein the demodulated frequency shift is proportional to the strain acting on the acoustic sensor. In an alternative embodiment,. a plurality of active fiber sensors may be pumped by a single laser light source with their outputs multiplexed together and fed through the receiving interferometer for interferometric analysis of all the signals.

Abstract: The invention concerns a method for inserting a service channel in the service channel plesiochronous frames. The method also consists in transmitting a time source block between a transmitter and a receiver of the frame, said method consisting in reserving in the frames, at transmitter level, at least a site for carrying the service channel data. The method is characterised in that it consists in: at the transmitter level: (i) inserting blocks (B) of the service channel in the reserved sites preceding each of these blocks (B) by a predetermined number n1 of identical bits (D), called start bits, and observing the following rules: in case there is no need for stuffing the remaining sites, starting the process at step (i) for a new block (B); in case there is need for stuffing the remaining sites, following each of the blocks (B) by a predetermined number n2 of identical bits (F), called stop bits, the stop bits being different from the start bits (D), and starting the process at step (i) for a new block (B); at the receiver level: detecting the regular occurrence of start bits (D) or the regular occurrence of start bits (D) preceded by the stop bits (F), for determining the presence of the blocks (B) in the reserved sites and extracting these blocks (B) from the reserved sites.
