A circulator connected to the isolator connects the transmitter to the isolator means and provides microwave energy to the antenna through the isolator and receives from the antenna again through the isolator the reflected microwave energy.  An indicator provides an indication of the watercut of the petroleum stream in accordance with the phase difference between the transmitted microwave energy and the test microwave energy.

Title: Detector for colliding signals in asynchronous communication
Inventor: AGGERS JOHN R
IPC: H04L12/403
Filed: 1989-12-11
Abstract: ABSTRACT OF THE DISCLOSURE        A communications system has an active master node which transmits request messages in serial bit fashion on a data bus, and a plurality of responder nodes each of which receives the request messages on the data bus and may respond to a request message with a serial bit answer message.  The possibility exists that a plurality of responder nodes may provide concurrent answer messages forming a composite signal which the active master node may not be able to recognize as containing answer message.  A low pass filter is provided in the active master node which provide as its output only those pulses in the composite signal whose length is within a predetermined interval, typically from approximately a tenth to one half of the interval for each bit in the answer messages.  A counter receives the low pass filter output and provides a collision signal to the associated master node if more than a preselected number of pulses within the predetermined interval are present.  By providing the collision signal only after detecting a plurality of these pulses in the low pass filter output, it is possible to avoid false detection of concurrent answer messages whose presence is simulated by noise on the line.

Title: Process for the removal of no and so from gas streams using a water-soluble, polymeric chelate of a polyvalent metal and membrane separation means
Inventor: GRINSTEAD ROBERT R
IPC: C01F11/48
Filed: 1990-05-07
Abstract: ABSTRACT         The invention is a cyclic process for removing NOx and SOx from a gas stream.  The gas stream is scrubbed with an aqueous reaction solution containing an organic, water-soluble 9 polymeric chelate containing a polyvalent metal ion.  The NOx is absorbed and in the presence of SOx, the imidodisulfonate is formed.  The aqueous reaction solution containing chelate and imidodisulfonate is contacted with a first separation membrane, wherein calcium oxide is added to the first permeate stream, resulting in the precipitation of calcium sulfite.  The calcium sulfite is filtered from the first permeate stream, the first permeate stream combined with the first non-permeate stream, and the combined stream contacted with a second separation membrane which removes a portion of the water and other low molecular weight materials.  The remaining non-permeate stream containing chelate is recycled to the scrubber.  Water-soluble alkali is added to the process as needed.   37,619-F

Abstract: A magnetic valve comprises a magnet coil (4), a valve shank (13) at the same time formed as a magnet armature, a valve plate (15) surrounding the valve  shank  (13),  at least one valve seat (17) and a resetting spring (16) which holds the plate  (15)  to  the  seat  (17)  when the magnet coil  (4)  is switched off.

Title: Toy vehicle spin-out wheel
Inventor: ROSENWINKEL DONALD A
IPC: A63H17/26
Filed: 1990-10-31
Abstract: TOY VEHICLE SPIN-OUT WHEEL A toy vehicle (10) With a pair of motor  (16) driven axles (14) each have hollow wheels (30) mounted adjacent a respective axle end (20) and in driving engagement with the axle through a resilient member (50, 72) that winds about the axle.  The inner end (54) of a coil spring  (50)  is releasably engaged by teeth  (25) rotating with the axle and the other end  (51)  is connected  to  the  inside  of  the  wheel  periphery.      Alternatively,  an elastic band  (72)  anchored to  the wheel periphery and engaged by the axle may be used.  As the axles are driven, rotation is transmitted to each wheel through the resilient member in a relatively loose condition as the toy vehicle is propelled along a generally unobstructed playing surface.  Upon a wheel encountering an impediment to the rotation of the wheel, the motor driven axle continues to rotate and winds the resilient member more tightly. If enough torque is thus transmitted through the wound up resilient member for the wheel  to  overcome  the  impediment,  or  if  the impediment is removed, the resilient member will unwind causing the wheel to spin-out more rapidly than it was being driven by the motor.   All  four wheels work independently so that different wheels may be spinning-out at different times.

Title: Inductively activated loudspeaker with conductive tube
Inventor: KLIPSCH PAUL W
IPC: H04R9/02
Filed: 1991-04-09
Abstract: ABSTRACT     An inductively activated loudspeaker produces sound by inducing an oscillating current in a shorted turn conductive tube that is positioned within a focused magnetic field.  The loudspeaker includes an electrically excitable stationary coil positioned within the magnetic field and in inductive relation to the conductive cylinder.  The oscillation of current within the stationary coil induces a corresponding oscillating current in the cylinder, which causes the cylinder to physically oscillate within the defined magnetic field.  The resultant vibratory movement of the diaphragm, upon which the cylinder is mounted, has the effect of creating sound.  Also disclosed is a combined stationary coil and outer pole assembly with internalized heat sinking, and which separably attaches to the remainder of the magnetic assembly of the loudspeaker.
