Title: Regenerative process and system for the simultaneous removal of particulates and the oxides of sulfur and nitrogen from a gas stream
Inventor: COHEN MITCHELL R
IPC: B01D53/56
Filed: 1991-11-21
Abstract: Dkt. No. 46-DV-2062 ABSTRACT OF THE DISCLOSURE            A process and system for simultaneously removing from a gaseous mixture, sulfur oxides by means of a solid sulfur oxide acceptor on a porous carrier, nitrogen oxides by means of ammonia gas and particulate matter by means of filtration and for the regeneration of loaded solid sulfur oxide acceptor.  Finely-divided solid sulfur oxide acceptor is entrained in a gaseous mixture to deplete sulfur oxides from the gaseous mixture, the finely-divided solid sulfur oxide acceptor being dispersed on a porous carrier material having a particle size up to about 200 microns.  In the process, the gaseous mixture is optionally pre-filtered to remove particulate matter and thereafter finely-divided solid sulfur oxide acceptor is injected into the gaseous mixture to form an entrained bed.  Ammonia gas is also injected into the exhaust gas stream.  A filter separates spent solid sorbent and particulate matter from clean gas.  A classifier is used to separate mixtures of spent sorbent from particulate matter.  A regenerator receives spent sorbents for regeneration and means are provided for passing regenerated finely-divided solid sorbent from the regenerator to the entrained bed reactor.  A preferred sorbent is copper oxide on porous alumina carrier.

Inventor: ONO KOICHI
IPC: H04N9/82
Filed: 1992-02-03
Abstract: A video signal is recorded in successive tracks on a recording medium together with a pilot signal, the latter having a frequency that changes cyclically with a different one of at least four frequencies in successive tracks. A field detector detects sequential fields in the frames of the video signal, and rotation of the usual rotary transducers is servo-controlled in response to the detected sequence of fields and a pulse that is generated as the transducers rotate to represent the rotational phase of those transducers. A pilot signal generator generates the pilot signal with an initial frequency determined by an initial field in the detected field sequence, and with this frequency changing as a function of the detected sequential fields.

Inventor: PARKS ROBERT A
IPC: G01N33/487
Filed: 1990-12-14
Abstract: A circuit is described for applying a potential to an electrode of a biosensing test cell, which electrode, when properly inserted in a female connector, is contacted by a pair spaced apart contacts. The circuit includes a source of excitation potential and an operational amplifier having one input connected to the source of excitation potential. A switching circuit is coupled between the operational amplifier and a first one of the spaced apart contacts, with the switch means exhibiting an impedance. A feedback circuit is connected between the second of the spaced-apart contacts and another input to the operational amplifier, to feed back a potential appearing at the second contact. The feedback is for the purpose of maintaining the output of the operational amplifier at a level which compensates for impedance losses in the swtiching circuit. The feedback circuit enables the output of the operational amplifier to be varied so that the potential applied to the electrode is equal to the source of excitation potential. A further circuit is connected to the feedback circuit for sensing when an open or high impedance state exists between the spaced-apart contacts.

Title: Assay method utilizing induced luminescence
Inventor: ULLMAN EDWIN F
IPC: G01N33/542
Filed: 1992-05-21
Abstract: Methods are disclosed for determining an analyte in a medium suspected of containing the analyte.   One method comprises treating a medium suspected of containing an analyte under conditions such that the analyte, if present, causes a photosensitizer and a chemiluminescent compound to come into close proximity.  The photosensitizer generates singlet oxygen and activates the chemiluminescent compound when it is in close proximity. The activated chemiluminescent compound subsequently produces light. The amount of light produced is related to the amount of analyte in the medium. Preferably, at least one of the photosensitizer and chemiluminescent compound is associated with a surface which is usually a suspendible particle, and a specific binding pair member is bound thereto.   Another method comprises providing (1) a medium suspected of containing the analyte, (2) a label reagent comprising a first specific binding pair (sbp) member associated with a photochemically activatable chemiluminescent compound wherein the first sbp member is capable of binding to the analyte or to a second sbp member to form a complex related to the presence of the analyte. This method further comprises photochemically activating the chemiluminescent compound. The amount of luminescence generated by the chemiluminescent compound is detected. The amount thereof is related to the amount of analyte in the medium.   Compositions and kits are also disclosed.
