Patent EP-0607371-A1 (EP)
Title: Appareil et procedes de reduction de bruit pour recepteurs de television
Inventor: HARFORD JACK RUDOLPH
IPC: H04N5/52
Filed: 1993-04-21
Abstract: Un récepteur de télévision hautes performances détecte de manière synchrone le signal FI image. Un bruit d'impulsion synchrone dans le signal FI génère soit du bruit à potentiel positif soit du bruit à potentiel négatif dans le signal vidéo fourni par un détecteur vidéo synchrone, lequel bruit est ensuite remplacé par une valeur du signal vidéo apparaissant avant le bruit d'impulsion de la manière suivante. Le signal vidéo contaminé par le bruit d'impulsion est fourni sous forme de signal d'entrée à la fois à un détecteur de bruit d'impulsion et à une ligne à retard. Le signal de sortie émanant de la ligne à retard, retardé d'environ 240 ns, est fourni comme signal permettant la poursuite par un circuit échantillonneur-bloqueur. Le signal de bruit d'impulsion détecté est utilisé pour actionner le mode de maintien dans le circuit échantillonneur-bloqueur. En étirant l'impulsion émanant du détecteur de bruit d'impulsion pendant la durée de 600-800 ns couvrant partiellement la durée de la majeure partie du bruit d'impulsion, le circuit échantillonneur-bloqueur remplace la majeure partie du bruit d'impulsion avec des valeurs préalablement mémorisées du signal vidéo retardé. Cela permet généralement d'éviter non seulement l'apparition, dans l'image télévisée, de bruit d'impulsion blanc et du bruit d'impulsion noir qui en résulte, mais également d'éviter l'application de bruit d'impulsion au canal de chroma recevant comme signal d'entrée un signal vidéo détecté de manière synchrone. L'excitation par impulsion du canal de chroma est ainsi évitée, et le "scintillement" du chroma n'apparaît pas dans l'image télévisée.

Title: Variable diameter rotor having an offset twist.
Inventor: FRADENBURGH EVAN A
IPC: B64C27/28
Filed: 1993-05-26
Abstract: A variable diameter rotor for a tilt rotor aircraft has an inboard section having a linear twist from a root end to an outboard end thereof, and an outboard section telescoped over the inboard section which additionally has a linear twist from a root end to an outboard end thereof. The outboard section is disposed at an offset of about 4 DEG  to 15 DEG  relative to the inboard section to provide a step wise change in twist angle when in the extended condition, such that the rotor when operated in the helicopter mode, can be operated at high blade pitch angles without premature stalling along the inboard airfoil surfaces This allows efficient operation at high thrust coefficient/solidarity ratios. Optionally, the trailing edge of the outboard section is rotated along the aft 30% of chord of the airfoil section to provide an equivalent twist increase in the offset at the transition between the blade sections. When in the forward flight cruise mode, the inboard equivalent twist increment allows operation of the inboard airfoil sections at higher pitch angles to reduce negative lift regions and increase cruise propulsion efficiency.

Title: Thioethers and dithioethers liposolubles contenus dans des preparations cosmetiques agissant contre le vieillissement de la peau chez l'homme
Inventor: HOLZNER GUENTER WOLFGANG
IPC: A61P17/00
Filed: 1993-07-26
Abstract: Chez l'homme, le vieillissement de la peau est essentiellement dû à l'action biochimique de radicaux libres, de peroxydes et des produits dérivés. Les thioéthers et les dithioéthers liposolubles contenus dans des préparations cosmétiques inactivent les peroxydes formés dans la peau et retardent de ce fait les effets du vieillissement.

Abstract: The novel Pb- and Cd-free glass frit composition, having a property profile which can be adjusted in a targeted manner, is distinguished by the fact that it contains, in addition to boron oxide, from 1 to 24 mol % of lanthanum oxide and from 0 to 10 mol % of silicic acid as network-forming oxides, and the molar ratio between boron oxide (B2O3) and lanthanum oxide (La2O3) is in the range from 3:1 to 99:1. A preferred composition essentially comprises no silicic acid. The properties of the compositions, including the softening point and the coefficient of expansion, can easily be adjusted by varying the amount of the principal constituents.

Abstract: Whereas conventional Ni/metal hydride button cells whose positive compressed-powder electrodes are produced from a mixture of Ni(OH)2, Ni powder and oxide compounds of cobalt suffer a massive irreversible capacity drop (curve 1) through an intensified high-temperature storage test at 65 DEG C, inserted in a cyclic treatment after n = 6 cycles, the same button cells exhibit a smaller and only temporary capacity decrease if from 0.1 to 15% of manganese and/or manganese oxide is also added to the positive bulk mixture (curve 2). The addition of manganese probably prevents reductive breakdown of a previously formed conductive CoOOH skeleton under the high-temperature storage conditions, by stabilising it or promoting its regeneration capacity. <IMAGE>

Abstract: A system and method for determining and displaying the status of client application programs executing on a multiprocessing server. Server process control blocks (5) and synchronization object descriptors (10) are created in the shared memory (11) of the server (3). Application program interfaces APIs (8) are linked to the control blocks and descriptors during the execution of the various multiprocessing application programs (7). A status utility (13) related to the service process monitor (12) selectively accesses information from the control blocks (5) and descriptors (10) to determine the status of the individual multiple processes executing on the server workstation (3). In a preferred form, the status information is conveyed to and displayed on a video display (4) associated with the service process monitor. In contrast to operating system monitors which disclose the status of all processes as a whole, the present server process monitor particularizes the information to the specific client process. Thereby, the information is of a granularity to identify processes which are hung up on semaphores, message queues, or the like. The information is at the level used by a system administrator or software developer.
