Abstract: A motor fuel additive composition comprises a mixture of:(a) from 5-50 weight percent, based upon the total weight of the additive, of a detergent component selected from the group consisting of (i) at least one nonionic compound having a molecular weight in the range of 200-1500, (ii) a reaction product of a substituted hydrocarbon and an amino compound, and (iii) a polybutylamine or polyisobutylamine; and (b) a fuel conditioner component comprising (i) from 2-50 weight percent, based upon the total weight of the additive, of a polar oxygenated hydrocarbon compound and (ii) from 2-50 weight percent, based upon the total weight of the additive, of an oxygenated compatibilizing agent. The fuel conditioner component may additionally comprise a hydrophilic separant, an aromatic hydrocarbon, or mixtures thereof. The additive may also additionally comprise a carrier oil or fluidizer. The additive is prepared by mixing together the detergent and fuel conditioner components, and is advantageous in that the detergent and fuel conditioner components synergistically interact to reduce both fuel intake system deposit formation and combustion chamber deposit formation, thereby inhibiting engine ORI.

Abstract: In rechargeable or primary electrochemical cells, hydrogen may evolve.  The invention concerns the use of an auxiliary electrode material comprising manganese dioxide and a catalyst as the oxidant providing for the recombination of pressurized hydrogen, for exam-ple, the hydrogen being at pressures ranging from substantially zero gauge pressure up to the relief pressure of the cell.  The cell is a sealed cell having a manganese dioxide cathode, a zinc anode and aqueous electrolyte contacting both anode and cathode.  The aqueous eletrolyte may be alkaline or it may be ammonium chloride or zinc chloride, or mixtures thereof.  The auxiliary electrode material, which may be mixed with the cathode material or be formed into a discrete auxiliary electrode, may optionally comprise a porous substrate, and in any event comprises MnO2 and a catalyst for the recombination of pres-surized hydrogen with the MnO2.  The substrate may be carbon black or graphite; the catalyst may be a metal, metal salt or metal oxide of elements such as lead, nickel, titanium, lanthanum, chromium, vanadium, tantalum and catalytically active alloys thereof.  Most particularly, the catalyst may be silver, platinum, sil-ver oxide, or silver dioxide.

Title: The use of 4-aminopyridine in the treatment of a neurological condition
Inventor: HANSEBOUT ROBERT R
IPC: A61P25/04
Filed: 1992-12-18
Abstract: The use of 4-aminopyridine to treat a neurological condition is described. In particular, the present invention relates to the use of 4-aminopyridine to treat spinal cord injured individuals. It has been found that 4-aminopyridine can reduce pain and spasticity in a spinal cord injured individual when given in doses from about 18 to about 30 milligrams intravenously. The results are quite significant due to the high incidence of these problems and the intractable nature of central pain in the spinal cord injured individuals. 4-Aminopyridine is also useful in increasing sensory ability and motor control.

Abstract: METHOD FOR IDENTIFYING MARKED FISH                Abstract of the Disclosure A method is disclosed for marking fish with bone-seeking marker elements and for identifying fish from the distribution of marker elements in the scales and bones of the fish. The method may be used to assist in identifying the sources and patterns of migration of wild stock fish by providing information about the order and relative concentrations of naturally occurring bone- seeking elements to which the fish have been exposed from the spatial distribution of such elements in the fish's scales and bones. Fish may be marked by exposing the fish to a marker element such as Strontium or one of the Lanthanide series of rare earth elements. The method for identifying marked fish involves taking a sample of bony tissue, for example a scale, from a fish, exposing a surface of the sample, and sampling the constituent elements of the sample along a path on the surface which traverses successive growth rings in the sample. The sampling may be done by laser ablation and Inductively Coupled Plasma Mass Spectrometry (ICPMS), a technique which is extremely sensitive and provides fine spatial resolution. Because the method is sensitive to the distribution of elements in the sample as well as the amounts of the elements in the sample it is possible to detect a marked fish even if the fish has been exposed to a high background level of the same marker element which was used to mark the fish. The invention also provides a method for marking fish by successive exposures to different marker elements or combina-tions of marker elements. This allows a large number of unique markings for fish using relatively few marker elements.

Title: Laser diode liquid-level/distance measurement
Inventor: MEINZER RICHARD A
IPC: G01S17/32
Filed: 1992-11-19
Abstract: A laser diode distance measurement device includes a laser diode assembly (10), comprising a laser diode and photodiode, which emits light (17) to a lens (19) which provides collimated light (20) incident on a float (22) which is covered with reflective tape on its top surface (24). The light (20) is reflected from the float (22) back to the laser diode assembly (10) which caused the assembly (10) to provide a signal having magnitude pulses (due to coherent interference) on a line (15) to a liquid level measurement circuit (14) related to the distance L to the float (22). Use of the collimated beam (20) and reflective tape on the float (22) minimizes speckle while providing adequate optical intensity feedback. The laser assembly (10) is driven by a sawtooth waveform signal that reduces electronic processing. The distance measurement circuit (14) blanks-out the feedback signal during discontinuities of the laser diode drive signal to minimize associated noise from distorting the distance measurement. Alternatively, the float may be omitted and the tube (11) made small enough to provide a meniscus effect curvature at a liquid surface (250) which provides a curved reflective surface to reflect the incident light (20), in a consistent fashion, back to the laser assembly (10).
