Title: Carbon black process control system
Inventor: BLAYLOCK CHARLES R
IPC: C09C1/48
Filed: 1990-07-06
Granted: 1996-12-03
Abstract: A carbon black process control system measures input variables such as feedstock flow rate, feedstock quality, air flow rate, air humidity, air temperature, fuel flow rate, fuel quality, and/or potassium additive solution flow rate at spaced intervals while the carbon black reactor is operating. Then, at spaced intervals in time one or more output variables of the carbon black, such as iodine number and/or DBP, are predicted in accordance with a prediction algorithm based on the values of the measured input variables. Then, at spaced intervals in time the predicted values of the output variables, such as iodine number and/or DBP, are averaged. Based on the average values of the predicted output variables, one or more input variables are then adjusted to achieve goal values of the predicted output variables, and thus obtain carbon black of substantially consistent quality. The predicted output variables are also laboratory measured from samples of the carbon black produced at spaced intervals in time while the carbon black reactor is operating. Then, based on both the predicted values and measured values of the output variables, the prediction algorithm is adjusted to improve the accuracy of the prediction of the output variables, and thus produce carbon black of substantially consistent quality.

Inventor: COYLE RICHARD JAMES JR
IPC: B23K26/02
Filed: 1990-11-28
Granted: 1996-02-13
Abstract: A method for fabricating optical components in the cladding of an optical fiber bus by the utilization of a laser. An excimer laser fabricates either an optical coupler opening or an optical mode scrambler by ablatively removing the cladding from the optical core of an optical fiber bus without damaging the optical core. Either coupler housing or a mode scrambler housing is attached to the optical fiber bus where the coupler or mode scrambler is to be fabricated. The coupler housing is used to position the laser, secure and align a coupler fiber, and provide cavities for junction and cladding repair materials. The mode scrambler housing serves a similar purpose.

Granted: 1998-04-14
Abstract: An antibody molecule or molecule containing antibody combining site portions (catalytic molecule) that catalytically hydrolyzes a preselected carboxylic acid amide or ester bond of a reactant ligand, methods of making and using the catalytic molecule, and cells that produce those molecules are disclosed.  The catalytic molecules bind to a reactant ligand containing the bond to be hydrolyzed and also to a haptenic ligand.

The haptenic ligand also contains a group that bears an ionic charge in aqueous solution at physiological pH values that is not present at a corresponding position of the reactant ligand.  The ionic charge-bearing group is located in the hapten within 7 .ANG.ngstroms of the tetrahedral carbon atom.

Title: Apparatus for correcting distorted sync in a composite video signal
Inventor: LAGONI WILLIAM ADAMSON
IPC: H04N5/21
Filed: 1991-04-04
Granted: 1995-10-24
Abstract: A television receiver includes a "one-chip" television signal processing IC which has a terminal for receiving a composite video signal including both image and synchronization pulse components. A composite video signal which has been non-linearly processed by a so-called "black-stretch" circuit is coupled to the composite video signal input terminal of the "one-chip" IC. In order that a sync separator of the "one-chip" IC can reliably separate the synchronization pulses from the composite video signal after it has been non-linearly processed, a sync correction circuit, including an auxiliary sync separator, is used to modify the synchronization pulses of the composite video signal after it is non-linearly processed and before it is coupled to the "one-chip" television IC.

Title: Vehicle mounted adaptor for a portable radio transceiver
Inventor: HIRASAWA NAOKI
IPC: H04W52/00
Filed: 1993-01-28
Granted: 1996-11-05
Abstract: A vehicle mounted adaptor is arranged to be coupled to a portable transceiver when the portable transceiver is used within the passenger compartment of the vehicle. The portable transceiver includes a main battery, a backup battery and a power switch circuit. The power switch circuit is supplied with power from either one of said main and backup batteries and generates a control signal when turned on for operating the portable transceiver. The adaptor includes a power switch which is coupled to a car battery mounted on the vehicle. The power switch of the adaptor is switched from an OFF position to an ON position when the control signal is generated and switched from the ON position to the OFF position when the control signal is terminated. The adaptor further includes a backup battery charger which is coupled to the power switch.          The backup battery charger serves to charge the backup battery when the power switch of the adaptor is in the OFF position.          Therefore, the backup battery charger is able to charge the backup battery even if the portable transceiver fails to generate the control signal due to a discharged condition of both the main and backup batteries.
