Abstract: An article and method for its manufacture are described. The article is preferably a ladle used in the manufacture of metals and receives molten metal for further chemical processing in the ladle or for transportation. The ladle is transparent to a wide range of electromagnetic radiation wavelengths which allows the metal to be heated or stirred by induction without heating the ladle itself. The ladle is made of glass fibers and an inorganic cement, and this provides strength along with high temperature resistance. The article is manufactured by winding glass fiber around a mandrel, the glass fiber having an inorganic cement adhered to it. In one technique, the cement is provided on the fiber as an aqueous slurry, and the product is allowed to air cure after winding. In a second technique, the cement is adhered to the fiber by electrostatic attraction. After winding is complete, additional cement may be added, the product is placed in an autoclave supplied with steam whereby the cement takes up water, and it is then allowed to cure. After the product is cured, it is preferably sawed into two pieces to form two inductively transparent ladles.

Abstract: PULSE MIG WELDER FOR WELDING THIN-WALLED COPPER-NICKEL PIPE                     Abstract A welding station for welding thin-walled copper-nickel pipe. An electronic welding station (10) has an output circuit (13) which provides arc welding power having the arc characteristics specified by a weld parameter selection circuit (12). A welding torch and feeder assembly (11) has a controller (20) which is responsive to a predetermined event, such as the passage of time since the start of the arc, or the average temperature of the pipe (25) as indicated by two temperature-measuring devices (30, 32). The controller (20) adjusts the wire feed speed, the pulse frequency, the pulse width, the welding voltage, the welding current and/or other parameters so as to cause the arc to have the parameters most desired for welding copper-nickel pipe. The present invention provides for a hotter arc for starting the welding operation, thereby obtaining good penetration and bonding, and a cooler arc for continuing the welding operation, thereby preventing burn-through of the pipe (25).

Title: Channel selection system for mobile radio communication equipment
Inventor: KAGE KOUZOU
IPC: H04W48/16
Filed: 1990-07-23
Granted: 1994-09-20
Abstract: A channel selection system for radio communication equipment which uses a control channel for interchanging control signals for connection and a plurality of data channels for interchanging data and emits an electromagnetic wave by using any one of the data channels after determining that it is idle by carrier sensing. The system rarely selects a data channel adjoining the control channel since the probability that such a data channel is registered as an idle channel is extremely low. The system, therefore, reduces the possibility of the equipment being unable to use the control channel due to the influence of power leaking from the data channel adjoining the control channel.

Title: Production of gasoline and distillate fuels from light cycle oil
Inventor: DERR WALTER R JR
IPC: C10G47/20
Filed: 1990-11-07
Granted: 1999-08-31
Abstract: High octane gasoline and high quality distillate are co-produced by a hydrocracking process in which a catalytic cracking light cycle oil is hydrocracked under conditions of low to moderate hydrogen pressure and severity to produce a high octane, hydrocracked gasoline. The distillate fraction which boils immediately above the gasoline fraction is recycled to the hydrocracker to increase the paraffinic content of this fraction by partial saturation and cracking of the aromatics contained in it so as to form a paraffinic distillate of low sulfur and high cetane index which is useful as a road diesel fuel. A higher boiling distillate fraction of relatively lower aromaticity may also be produced for use as a low sulfur fuel oil. The recycled fraction may be cooled to provide quench for the hydrocracker.

Title: Super high frequency oscillator/resonator
Inventor: LEGGE RONALD
IPC: H03H9/24
Filed: 1990-12-27
Granted: 1995-10-24
Abstract: A method of filtering an AC signal using a piezoelectric beam is provided.  A piezoelectric film is formed on a mechanical support and a portion of the piezoelectric film forms a beam which extends beyond the mechanical support so that a cavity is formed underneath the beam, and the beam is free to vibrate in the cavity at a resonant frequency when an acoustic wave is propagated in the piezoelectric layer.     A depletion region is formed under a Schottky contact which serves as a drive electrode.  An unfiltered AC signal is coupled to the drive electrode thereby establishing an acoustic wave when the unfiltered AC signal comprises a component at the resonant frequency.  Surface charge on the piezoelectric film resulting from vibration of the beam allows the resonant frequency component of the unfiltered AC signal to pass through the depletion region.  Alternatively, the resonant frequency component can be passed by a tunnel current through the cavity.

Title: A method and a device for sensorless control of a reluctance motor
Inventor: HEDLUND BENGT GUNNAR
IPC: H02P6/18
Filed: 1990-07-20
Granted: 1996-03-12
Abstract: In a method for sensorless control of a reluctance motor the actual magnetic flux is compared with tabulated values of the non-linear function between the magnetic flux and the current for the angular position at which a commutation signal (via P15-P18) is to be emitted to the power stages (1-4) for the stator pole windings (H10-H13) of the motor.   The actual value of the magnetic flux is calculated for each sample interval, based on the sampled values of  voltage  (u via P7)  and  current  (i via P8) according to the relation .DELTA.? = (u-R.i).DELTA.t, where R is the resistance of the actual pole winding and the actual power stage.  The instantaneous flux value .DELTA.? received is added to the value of the magnetic flux previously received.          The added value constitutes the actual value, referred to above, which is to be compared with tabulated values.
