Title: Neuronal cholinergic differentiation factor
Inventor: RAO MAHENDRA S
IPC: C07K16/00
Filed: 1991-12-19
Abstract: The present invention is directed to a target-derived neuronal cholinergic differenciation factor (NCDF), and the therapeutic and diagnostic uses thereof. The invention provides NCDF, and derivatives, analogs, and fragments thereof, pharmaceutical compositions containing the foregoing, as well as anti-NCDF antibodies. The NCDF of the invention is a protein present in extracts of mammalian sweat glands, which exhibits heat and trypsin lability, lack of substantial binding to a heparin-agarose affinity column, an isoelectric point (pI) in the range of approximately 4.8 to 5.2, a non-membrane cellular localization, and an approximate molecular weight in the range of 16 to 32 kilodaltons. The NCDF protein, its derivatives, analogs, and fragments are able to reduce the expression of tyrosine hydroxylase and of total catecholamines, and increase the expression of choline acetyltransferase and vasoactive intestinal peptide (VIP), by sympathetic neurons in cell culture. The NCDF protein, its derivatives, analogs, and fragments, can be used to induce cholinergic activity in neurons. Such proteins, derivatives, analogs and fragments can be administered therapeutically to patients with nervous system damage or diseases where it is desirable to support survival and/or cholinergic differentiation of a number of neuronal types.

Title: Method of promoting the decarburizsation reaction in a vacuum refining furnace
Inventor: HUNTER PHILIP B
IPC: C21C7/10
Filed: 1992-01-07
Abstract: This invention describes a method to promote the decarburization reaction of the molten steel in a vacuum refining furnace by adding manganese ore into the molten steel. The added manganese ore melts and releases oxygen into the steel bath with the additional dissolved oxygen content effectively promoting the decarburization reaction of carbon steel, even below the 50 ppm level of ultra-low carbon content. The addition of the manganese ore increases the oxygen content of molten steel and enables the vacuum degassification treatment to have an effect similar to that of gaseous oxygen blowing without the excessive refractory erosion of the vacuum chamber lining. In this manner, baths having relatively high carbon contents and/or low dissolved oxygen contents can be effectively decarburized to ultra-low carbon levels. This invention and the addition technique are not limited in application to RH  vacuum-degassing equipment. Most vacuum furnaces are in general suitable for applying this manganese ore addition for the purpose of facilitating the production of ultra-low carbon steel.

Title: Coal pulverizer purifier classifier
Inventor: BROWN CHARLES K
IPC: C10L5/00
Filed: 1993-08-09
Abstract: ABSTRACT      A  fuel  coal  processing  system  is  provided  which consists  of  a centrifugal type pulverizer, a coal purifier and an optional fuel coal size classifier, all combined into one  integral,  cooperatively  acting, fuel coal preparation device.   The  pulverizer  consists  of  a  pair  of opposed multicup  concentric  ring rotors, mounted on a common axis, counter  rotating  at  relatively  high  speed,  an  axially located  feed  tube  through  which material is fed into the center of the rotor system and then is thrown tangentially, progressively and outwardly from ring to ring on each of the counter rotating rotors thereby being reduced in size by the repeated high speed impacts and skidding abrasion associated with  the process.  The purifier consists of an annular ring nozzle  surrounding  the  outer  periphery of the pulverizer rotors  through  which  high  velocity  air streams upwardly through  the  spray  of  pulverized  material  exiting  the pulverizing  rotors  to vertically accelerate the less dense pure  coal  particles  to  strata relatively higher than the more  dense impure material.   The pyritic material is split off and rejected while the coal product then passes through size  clarifier  means.  Oversize coal is thrown out of the air   stream  and  is  returned  to  the  mill  for  further reduction.   Triboelectrostatic  purification means may also be  used  alone or in conjunction with the aerodynamic means to more effectively handle different conditions and kinds of coal.

Title: Helicopter Recognition Radar Processor
Inventor: ABATZOGLOU THEAGENIS J
IPC: G01S13/524
Filed: 1993-08-19
Abstract: A radar processor is disclosed for processing the radar return samples  from a Doppler radar receiver to discriminate helicopter targets from fixed-wing targets. The samples are passed through a helicopter filter which eliminates the target skin Doppler return, and passed the sidebands about the target skin return which are due to the helicopter rotor hub modulation.  The coefficients of the helicopter filter are selected to maximize the signal-to-noise ratio.  The radar processor requires only a few milliseconds on target  for reliable detection and can, therefore, be easily implemented by scanning surveillance systems.

Title: Method of treating wastewater
Inventor: TIMPANY PETER L
IPC: C02F3/12
Filed: 1993-10-19
Abstract: ABSTRACT     Conventional biological processes for treating wastewater include the so-called activated sludge process which is  continuous and  the sequencing batch reaction (SBR) activated sludge  process.          The  first  process  requires  the  use  of  dedicated,  relatively expensive   external  clarifiers,   and  the  second   process   is inefficient  in terms of treatment volume.   A modified  sequencing batch reactor process and system enable the  efficient,  continuous treatment and discharge of wastewater,  combining the advantages of the  SBR  and activated sludge processes.   In  the  present  case, wastewater  is  initially  fed  in  a  first  direction  through  a plurality of contiguous cells,  the wastewater is subjected at  all times to  biological treatment in a plurality of  such  cells  and settled in at least one of the cells immediately prior to discharge from the system.   In subsequent steps,  the wastewater is fed into the  system  at  different locations for  following  a  variety  of biological  treatment steps and paths through  the  cells,  whereby selected  aerobic  treatment cells become settling cells  and vice versa, so that wastewater is introduced and discharged  from  the system in a fixed rotating pattern.  The activated sludge generally flows in the same direction as the wastewater but receives settling and  separation from the wastewater immediately prior to  discharge of treated wastewater from the system.

Title: Portable optical reader system
Inventor: LASER VADIM
IPC: G06K7/10
Filed: 1992-07-23
Abstract: A portable optical reader system for reading optical information over a substantial range of distances includes a casing having a light receiving opening for alignment with optical information.  Further included is a reading sensor for converting a reflected light image of optical information into an information signal and reflected light optical elements for forming a reflected light image. The optical system is adjustable to tend to focus a reflected light image of optical information, located within a substantial range of distances, onto the reading sensor. A light beam generator is associated with the casing and directed relative to the optical elements and the light receiving opening such that a light beam generated thereby will impinge on an information carrier, having optical information to be read, and will be reflected therefrom through the light receiving opening and via the optical elements to the reading sensor. Since the position of impingement of the reflected light beam on the reading sensor is a function of the range of the information carrier from the image sensor, the optical system may be adjusted to focus a reflected light image of optical information associated with the information carrier, at least in part, according to the position of impingement of the reflected light beam on the reading sensor.
