IPC: H04N9/64
Filed: 1995-03-30
Abstract: An amplifier (60) provides an amplified video signal in response to a video input signal supplied thereto. A cathode current sensor (Q3), couples an output of the amplifier to the cathode of a kinescope (20) and also provides an output current (Ik) proportional to the kinescope cathode current. A feedback path (82) applies a portion of the sensed cathode current provided by the cathode current sensor to a circuit node (65 or 63) in the amplifier for imparting gamma correction to images produced by the kinescope. In one application the cathode current is apportioned (Q3) to provide gamma correction for the kinescope and to provide automatic kinescope bias (AKB) control.

Abstract: The invention relates to a process for improving the purity  and,  in particular,  the  color  and  odor quality of useful  materials  and mixtures  of useful materials from the field of wetting agents, detergents and/or cleaning products.  The process is characterized in that a starting material containing impurities and, in particular, steam-volatile impurities is treated with the superheated steam in finely divided form at normal pressure,  bleaching agents optionally being used to produce improvements in color.       In  one  particular  embodiment,  the  invention relates to the use of the process for drying aqueous preparations of useful materials and/or mixtures of useful materials  from the  field of wetting agents, detergents and/or cleaning products in a spray drying zone and/or fluidized bed using superheated steam as the drying  gas  for  the  simultaneous  purification  of  a starting material containing in particular steam-vola-tile impurities.   This purification treatment may be combined with oxidative or reducing bleaching simul-taneously initiated in the treated material to produce light-colored  useful  materials  or mixtures  of  such useful materials.   If desired, ozone may be added in traces to the superheated steam.

Title: Firing head connected between a coiled tubing and a perforating gun adapted to move freely within a tubing string and actuated by fluid pressure in the coiled tubing
Inventor: HUBER KLAUS B
IPC: E21B23/04
Filed: 1995-06-06
Abstract: A firing head adapted to connected between a coiled tubing and a perforating gun, is sized and shaped to enable it to move freely within a tubing string in the wellbore, may be actuated by fluid pressure within the coiled tubing, and includes a circulation and recirculation feature wherein wellbore fluid may be circulated through the firing head between the coiled tubing and an annulus around the tubing string, the circulation taking place either before or after detonation of the perforating gun. Three firing heads are discussed. One such firing head is a Circulation Direction Firing (CDF) Head. The CDF firing head circulates fluid from the wellbore to the coiled tubing and depresses a piston. Then, fluid pressure from the coiled tubing lifts the piston uncovering locking balls and propelling a firing pin to a booster of a detonating cord detonating the CDF firing head. Fluid circulation from the coiled tubing to the wellbore annulus begins after the CDF firing head detonates. Another such firing head is a Circulation Ball Firing (CBF) Head.  The CBF firing head circulates fluid from the wellbore to the coiled tubing, receives a ball, and uses fluid pressure in the coiled tubing to lift a piston, uncover the locking balls and detonate the CBF  firing head. Another such firing head is a Ball Actuated Circulation Firing (BCF) Head. The BCF  firing head circulates fluid from the wellbore to the coiled tubing, receives a ball from the wellbore surface, and uses fluid pressure in the coiled tubing to push a piston downwardly which uncovers the locking balls and detonates the BCF firing head. Recirculation is permitted after the firing head detonates.

Title: Process and device for the posttreatment of welded compound panels
Inventor: URECH WERNER
IPC: B23K31/00
Filed: 1995-06-19
Abstract: In a compound panel welding line, the compound panels discharged from a welding machine are cooled by means of a cooling unit.  In the cooling unit, the welded seam is treated with a cooling fluid, in particular a rust-preventative oil.   This allows the panels to be cooled and oiled within a very short time and over a very short distance, thus substantially reducing the overall length of a welding line, and greatly facilitating the handling of the compound panels.

Le paramètre orthogonalité est calculé en proportion de la valeur actuelle de la durée des impulsions, dans des conditions d'orthogonalité des impulsions adjacentes et selon le principe d'incertitude. Le paramètre robustesse est calculé en fonction de l'accélération actuelle de l'objet.

Filed: 1994-07-15
Abstract: L'invention concerne un appareil et des procédés de mesure des tensions en oxygène dans des systèmes biologiques faisant appel à un matériau paramagnétique physiologiquement acceptable, tel que l'encre de Chine ou le noir de carbone, et à l'oxymétrie par résonance paramagnétique électronique (RPE). L'encre de Chine est introduite dans le système biologique et exposée à un champ magnétique et à un champ électromagnétique compris entre 1 et 2 GHz. Les spectres RPE sont ensuite mesurés au niveau du système biologique afin de déterminer la concentration en oxygène. Les spectres RPE sont déterminés par un spectromètre RPE qui règle le résonateur à une fréquence de résonance unique afin de compenser les mouvements du système biologique, par exemple un être humain ou un animal. Le système biologique peut également être constitué d'autres tissus, cellules, et cultures de cellules in vivo, ce qui permet de mesurer directement la concentration en oxygène (pO2) de façon non destructive.

Title: Method and apparatus for storing and presenting visual and audible information to an individual
Inventor: MORAN RICHARD P
IPC: G11B7/0037
Filed: 1994-10-28
Abstract: A method and apparatus for storing and presenting visual and audible information to an individual. Audio source signals from each channel of a stereophonic audio source (44) are processed by a microcontroller-controlled circuit (48) that also receives commands from a programmer. The commands from the programmer cause the generation of pulsed control signals for each channel. The pulsed control signals contain only low audio frequencies. The audio source signals are processed so that their spectral frequencies are translated above the low audio frequency range of the pulsed control signals and inverted. The pulsed control signals for each channel are then added (110) to the corresponding processed audio source signals to produce two combined audio signals (112). Each combined audio signal contains both the processed audio source signals and the pulse control signals. The combined audio signals are then recorded on a compact disc.
