Abstract: A spread spectrum communication system for direct sequence transmission of digital information having a modulation format which is particularly suitable for indoor communication within residential, office and industrial structures. The modulation format combines BPSK or MSK spreading with FM carrier modulation by data bits and a carrier frequency shift whose magnitude is related to both a chip rate and a spreading sequence length. The carrier, chip clock and data clock are all synchronous and the sequence length is an integral submultiple of the bit length. The system reduces the frequency error between the transmitter chip clock and the receiver chip clock to permit the elimination of a code phase tracking loop in the receiver to reduce the receiver complexity. The receiver has an extended dynamic range which makes possible the reception of very strong signal without an automatic gain control loop (AGC) as well as reducing the time needed for code phase acquisition. The transmission system is highly resistant to CW jamming and short distance multipath effects. <IMAGE>

Title: Vtol aircraft
Inventor: MOLLER PAUL S
IPC: B64C29/00
Filed: 1991-01-11
Granted: 1995-11-22
Abstract: A VTOL aircraft including a fuselage with four nacelles, three vertical stabilizers and a horizontal stabilizer attached to the fuselage. The fuselage and the nacelles are lifting bodies that are configured to jointly form an aerodynamic lifting body which cooperates with the horizontal stabilizer to provide aerodynamic lift to the aircraft in forward flight. Each nacelle contains two rotary engines directly driving corresponding fans which face each other and operate in counter-rotating directions. Each nacelle also contains a system of vanes located at the rear opening thereof, and actuators for extending and retracting the vanes to deflect the airflow over a predetermined range of angles from the horizontal. Each engine utilizes the dynamic pressure of the air behind the fans to provide a source of air for cooling the rotors and exhaust system. A triple redundant computerized flight control system maintains the stability of the aircraft as it transitions from one flight regime to another as well as in flight. The system of vanes alone can also be used as an apparatus for gas or fluid stream directional control.

Abstract: Dans le cas des télécopieurs, le codage se faisait jusqu'à maintenant sur la base du principe des longueurs de projection, c'est-à-dire, tous les points d'image de même couleur sont saisis numériquement jusqu'à ce qu'un changement survienne, et sont codés selon le procédé MHC. La transmission se fait ensuite sur la base de la modulation de la différence entre les phases ou de la différence entre les amplitudes et les phases. Dans le cas de la télévision, l'utilisation de différentes porteuses causait des perturbations connues sous les noms de 'cross colour' et de 'cross luminance'. La présente invention permet de réduire les délais dûs au codage dans le cas des télécopieurs, étant donné que seuls les chiffres individuels composant les nombres sont codés, par exemple les chiffres 1 à 0 pour blanc et noir. Le codage ne requiert ainsi que 20 combinaisons. Le temps de transmission est encore réduit en condensant toutes les lignes uniquement blanches. Dans le cas de la télévision, une condensation par multiplexage de codage de tous les signaux permet d'utiliser une seule porteuse.

Abstract: To combat oil spillages and for rapid uptake of the escaped oil or oleaginous substances, there serves a process in which high-temperature-blown glass wool is hydrophobised and simultaneously bound using silicone and a starch serving as binder. The glass wool treated in accordance with this is then combined to form a cuttable, mat-shaped framework and is expediently dried at 150 DEG C. The then cohering three-dimensional framework mats are applied to the contaminated water sites and are left there for complete absorption, and are then together with the absorbed oil, subjected to intermediate storage and then mechanically or thermally disposed of or reprocessed. A corresponding adsorber is composed of this fine-fibre glass wool which is prepared and configured by coating with silicone and starch in such a way that adsorption of the oil away from the water surface or the ground surface is then possible. <IMAGE>
