Title: Method of producing superconducting wire
Inventor: SAITO SHIGEO
IPC: C01G1/00
Filed: 1988-03-25
Granted: 1991-07-23
Abstract: TITLE OF THE INVENTION    METHOD OF PRODUCING SUPERCONDUCTING WIRE     ABSTRACT OF THE DISCLOSURE    The  present invention relates to a method of producing a superconducting wire, in particular to a novel method of producing a ceramics superconducting wire.    The  ceramics  superconductor has  been  obtained  by sintering metallic powders containing raw material ingredients but the resulting ceramics superconductor has been remarkably fragile,  wanting  in ductility,  and  inferior  in  bending strength, so that it has shown a problem in that it can not be turned into a long wire.    The present invention was achieved in order to solve the above described problem and can provide a long superconducting wire  by continuously coating a  long  substrate with raw material powders composing the ceramics superconducting wire and then sintering it in a temperature range in which a superconducting layer can be formed.

Abstract: Abstract of the Disclosure A cigarette paper which when fabricated into a cigarette with a suitable tobacco column produces up to 80% less particulate sidestream smoke than do cigarettes fabricated with conventional cigarette paper wrappers.  This reduction of sidestream smoke is accomplished by incorporation of a mixture of freshly precipitated and particulate magnesium hydroxides in the cigarette paper sheet as paper fillers.  The high percentage reductions in sidestream particulate smoke are obtained when the median particle size of the particulate magnesium hydroxide filler is relatively large, e.g., 15 micrometers.

Title: Refrigerant reclaim method and apparatus
Inventor: VAN STEENBURGH LEON R JR
IPC: F25B45/00
Filed: 1988-10-12
Granted: 1994-04-12
Abstract: ABSTRACT          A refrigerant reclaim system includes a compressor, a heat exchanger, an oil separator, a condenser, a chill tank, a filter-dryer and a cooling coil in the chill tank. Refrigerant to be reclaimed is drawn through the cold side of the heat exchanger, converted to a gas which is discharged into the oil separator where the gas is directed upwardly in an expanding stream.  The flow of the stream is abruptly interrupted to separate oil from refrigerant.  The gaseous refrigerant is passed from the oil separator through the compressor, the hot side of the heat exchanger, a condenser and into the chill tank in a liquid state.  Liquid refrigerant flows from the bottom of the chill tank through a filter-dryer, an expansion device, converting it to gas, through a cooling coil, submerged in liquid refrigerant in the chill tank, into the stream exiting the oil separator and back to the compressor.  Controls are provided for shutting down the cold side of the heat exchanger and the oil separator while the chill tank, filter-dryer, cooling coil, compressor and condenser continue to be active.

Granted: 1995-08-15
Abstract: A process is disclosed for fractionating lignocellulosic materials fast-pyrolysis oils to produce phenol-containing compositions suitable for the manufacture of phenol-formaldehyde resins.  The process includes admixing the oils with an organic solvent having at least a moderate solubility parameter and good hydrogen bonding capability, the solvent extracting the phenol and neutral fractions from the oils.  The organic solvent-soluble fraction containing the phenol and neutral fractions is separated from the mixture and admixed with water to extract water-soluble materials therefrom.  The organic solvent-soluble fraction is then separated from the water fraction and admixed with an aqueous alkali metal bicarbonate solution to extract strong organic acids and highly polar compounds from the solvent fractions.  Finally, the residual organic solvent-soluble fraction is separated, and the organic solvent is removed therefrom to produce the phenol-containing compositions.

Abstract: A circuit is provided for the measurement and recognition of maximum or minimum voltages coming for example from a frequency selective measurement objective and in particular from an electronic filter. A fixed measurement frequency is fed to the measurement object. The measurement object is balanced by a stepwise change of a tuning voltage. The output voltage generated by the measurement object is fed to a switch after rectification and amplification, which switch is clocked with a clock signal. The output voltages of the switch are fed to an intermediate storage. The output voltages of the intermediate storage are supplied to a differential amplifier via an intermediate switch actuated by a control clock cycle. If the output voltage reaches an extremum such as a maximum then the stepwise change of the tuning voltage is interrupted. The value determined for the tuning voltage is stored in a memory such as a random access memory, the contents of which represents the optimum for the tuning of the measurement object such as for example the filter.
