Abstract: When a transport packet of the MPEG2 signal is recorded, a tape speed is reduced to 1/2 or 1/4 of that used to record standard data in accordance with the bit rate of the program. Twa heads (A and B) having different azimuths are provided in close proximity with each other at the same height on a drum. If the 1/2 tape speed mode is selected, the recording is performed by head A during the first scan of the tape and by head B during the next scan. Even when the tape speed is a fraction of an even number of the standard tape speed, the azimuth angles of adjacent tracks are different and azimuth recording is performed to reduce crosstalk.

Abstract: An optically clear hydrophobic coating is prepared by combining in the presence of water fluorinated polysiloxane having multiple hydrolyzable side groups selected from the group including alkyl, aryl, or alkoxy groups having from one to four carbon atoms, with polysiloxane, with polyester modified polysiloxane, with acid, and with alcohol. The polysiloxane ingredients are combined and blended together. The acid and alcohol ingredients are combined together and mixed with the polysiloxane ingredients. The polysiloxane ingredients undergo hydrolysis and polycondensation/polymerization reactions to form a fluorinated polyester modified polysiloxane polymer that when applied to a substrate surface cures at ambient temperatures to form a durable, weather, chemical and heat resistant, optically clear hydrophobic protective coating.

Title: Catheter mapping system and method
Inventor: WITTKAMPF FREDERIK H M
IPC: A61B5/296
Filed: 1996-11-01
Granted: 2008-10-07
Abstract: A system and method are provided for catheter location mapping, and related procedures. Three substantially orthogonal alternating signals are applied through the patient, directed substantially toward the area of interest to be mapped, such as patient's heart. The currents are preferably constant current pulses, of a frequency and magnitude to avoid disruption with ECG recordings. A catheter is equipped with at least a measuring electrode, which for cardiac procedures is positioned at various locations either against the patient's heart wall, or within a coronary vein or artery. A voltage is sensed between the catheter tip and a reference electrode, preferably a surface electrode on the patient, which voltage signal has components corresponding to the three orthogonal applied current signals. Three processing channels are used to separate out the three components as x, y and z signals, from which calculations are made for determination of the three- dimensional location of the catheter tip within the body. An easy calibration procedure, which can be performed separately or during the mapping, is used to calibrate the system and provide the correlations between respective x, y and z sense signals and dimensional locations. The procedure is particularly applicable for catheter mapping prior to ablation, and for repositioning the catheter tip at precise locations for the desired ablations. The procedure is also applicable for other techniques where position must be remembered and re-found with accuracy, such as in mapping coronary stenosis and/or placing stents. Although the invention provides the greatest benefit in 3- dimensional applications, it is also useful for one and two dimensional applications.

Abstract: A pyrolysis batch process is disclosed for recycling hydrocarbon containing used material such as plastics including ABS, polystyrene styrene and other non-chlorinated hydrocarbons, car fluff such as solid plastics, foam plastics, fabrics and the like, and more particularly scrap tires so as to obtain useful light oil and fuel gases. Used tire cuttings are loaded into a rotatable reactor which is closed, evacuated, rotated and heated until exothermic reaction is initiated. The reactor internal pressure is then allowed to increase to and is regulated within the range of atmospheric pressure and above. Upon continuing reactor rotation and heating, condensable hydrocarbon vapors and gaseous hydrocarbons are produced. The vapors are condensed into oil while the gaseous hydrocarbons are used as a fuel for reactor heating. At the end of the batching operation, the reactor is air cooled prior to reactor opening and unloading of the solid residues namely carbon black residues, wire mesh and/or some other fibrous materials such as Kevlar® having a high temperature decomposition point.

Abstract: L'invention concerne des compositions de solvant extrêmement pures constituées par des n-paraffines et des isoparaffines, ces dernières contenant des branches méthyle prédominantes, dont le rapport entre isoparaffine et n-paraffine est suffisant pour leur conférer des propriétés supérieures à basse température, ainsi qu'une faible viscosité. On prépare ces compositions au moyen d'un procédé consistant à effectuer la réaction d'une charge paraffinique cireuse ou à longue chaîne, particulièrement une cire de Fischer-Tropsch, au-dessus d'un catalyseur à double fonction, de manière à produire des réactions d'hydroisomérisation et d'hydrocraquage à des niveaux de conversion de 700 DEG F+ dans une plage de 20 à 90 % en poids, afin d'obtenir une fraction brute de C5 à 1050 DEG F. On effectue ensuite la distillation primaire de cette fraction par l'intermédiaire d'une distillation atmosphérique, afin de produire une fraction à point d'ébullition bas comportant un point d'ébullition d'extrémité supérieure situé entre 650 DEG F et 750 DEG F. On fractionne cette dernière fraction à point d'ébullition bas et on en obtient un solvant présentant une plage étroite d'ébullition, qu'on peut diviser encore en grades de solvant présentant diverses plages d'ébullition.

Title: Synchrodyning of vsb and qam final i-f signals supplied by separate converters in a qam/vsb digital tv receiver

Abstract: A QAM/VSB digital television (DTV) receiver of plural conversion type uses the same circuitry up to a penultimate IF amplifier for receiving DTV signals no matter whether they use QAM or VSB modulation. The converter used for generating final IF signals when QAM modulation is received and the converter used for generating final IF signals when VSB modulation is received have respective mixers and respective local oscillators with separate automatic frequency and phase control. The use of such separate converters avoids a lock-out from VSB reception mode that otherwise can occur during the reception of DTV signals with VSB modulation.
