Title: Conferencing arrangement for compressed information signals
Inventor: NAHUMI DROR
IPC: H04N7/15
Filed: 1994-02-03
Granted: 1997-12-23
Abstract: A conferencing bridging technique for compressed information signals which monitors the signal energy transmitted by each conferee. When there is only one conferee speaking, the summing circuit in the bridge unit is bypassed along with the speech decoding/coding apparatus and the talking conferee's signal is broadcast to all conferees. If there is more than one conferee speaking at any given time, then only the speaking conferee's signals are routed to an associated speech decoder wherein those conferees' compressed signals are decompressed. These decompressed signals are then combined by the summing circuit and the sum is recompressed and broadcast to all conferees. Advantageously, the above-describedtechnique eliminates the signal degradation associated with tandeming of signal decoding and coding operations and permits the sharing of a smaller number of signal decoders among a larger number of conferees.

Title: Helicopter engine control having lateral cyclic pitch anticipation
Inventor: EBERT FREDERICK J
IPC: G05D1/00
Filed: 1992-08-27
Granted: 2003-06-10
Abstract: A helicopter engine fuel control anticipates changes in main rotor torque in response to lateral cyclic pitch commands; to thereby minimize engine and main rotor speed droop and overspeed during left and right roll maneuvers. A fuel compensation signal (100,101) is summed with a helicopter fuel control (52) fuel command signal (67) in response both to a lateral cyclic pitch command signal (LCP) (107) from a pilot operated cyclic pitch control exceeding a left or right threshold magnitude (201, 210) and a total lateral cyclic pitch command signal (TCP) (108) from a lateral cyclic pitch control sys-tem exceeding a left or right threshold magnitude (202; 207, 215, 220): The anagnitude of the fuel compensation signal is dependent upon the direction of TCP and LCP, e:g., left or right; and helicopter roll acceleration (115). Alternatively, the magnitude and duration of the fuel compensation signal is dependent upon the rate of change in commanded lateral cyclic pitch (107, 400, 407): A limiter (120) limits the magnitude of the fuel compensation signal. The fuel compensa-tion signal is overridden (127, 125, 103) When it is increasing fuel flow (303) during rotor overspeed (128, 301); and when it is decrea-sing fuel flow (311) if rotor acceleration (130, 133) is negative (310) during rotor droop (128, 301).

Abstract: Defects in wooden boards, such as knots, knotholes or cracks, are repaired by forming an opening in the board at the site of the defect and forming a plug that fills the opening. In some forms of the invention the opening has a shape which interlocks the plug to the board. In another form of the invention, the plug is held in place by a transversely extending resilient member that is embedded in the plug and which is under tension which causes edge portions of the member to bite into or bear against the adjacent wood. Forming the opening includes cutting away bark encasement tissue that may adjoin the defect which encasement can cause a discoloration upon painting of the board and may eventually loosen. In some forms of the invention, cracks are repaired by making plural saw cuts along a crack to form the opening with the saw having a different angling relative to the board during each saw cut. In another form of the invention, the opening and plug extend between opposite surfaces of the board and have a width which increases at a plurality of spaced apart locations within the board and decreases at a plurality of alternate locations.

Title: Two stage carbonizer
Inventor: STATS DAVID A
IPC: C10J1/207
Filed: 1994-09-22
Granted: 1998-02-03
Abstract: A two stage carbonizer places as much heat as possible into the gas streams entering the carbonizer to drive off volatile matter and reduce tars and oils by thermal cracking which is enhanced by the addition of sorbent. The carbonizer operates as a fluidized bed with a combustor providing flue gas as one fluidizing medium and preheated air as the other. This allows the coal to be devolatilized and the tars and oils to be thermally cracked due to the direct contact with the coal and hot flue gas. The device is designed to operate at high pressures from about 12-20 atmospheres.

Title: Method for reproducing douglas-fir by somatic embryogenesis
Inventor: GUPTA PRAMOD K
IPC: C12N5/00
Filed: 1995-02-23
Granted: 2000-04-18
Abstract: The invention is a method for reproducing Douglas-fir by somatic embryogenesis using plant tissue culture techniques in a multistage culturing process. A suitable explant, typically the fertilized embryo excised from an immature seed, is first cultured on a medium that induces multiple early stage embryos. These are multiplied in a second culture having reduced growth hormones where the early stage embryos grow in size and vigor to advanced early stage embryos. The embryos may then be transferred direclty to a cotyledonary embryo development culture containing an adsorbent such as activated charcoal.  Preferably, they are first singulated by shaking in two or more liquid subcultures containing the adsorbent prior to placing them on the development medium. After several weeks somatic embryos having the appearance of zygotic embryos will have formed. These may be germinated before or after storage and transplanted to soil for further growth.

Abstract: The arrangement of a gas turbine engine suitable for high bypass ratio aircraft engines in which gases circulate in a primary air channel (7) and a secondary channel (8) concentric to said primary air channel, is characterized in that structural vanes (22) connecting the channel delimitation casings (2, 10, 14, 5) with each other, alternate with aerodynamic vanes (20) for guiding the gases on a common circumference of the engine bypass air channel (8), and in that the structural channels branch out between the two channels. The resulting advantages are simplicity of construction associated with a reduction in the space required for housing the channels and good resistance without notable increase of the total mass.
