Title: High silica crystalline zeolites and process for their preparation
Inventor: DAVIS STEPHEN M
IPC: C01B39/32
Filed: 1990-06-26
Abstract: ABSTRACT OF THE DISCLOSURE           Crystalline    aluminosilicate    zeolites having increased silica to  alumina mole ratios  are prepared by a process  wherein a conventional  crys-talline aluminosilicate zeolite is treated to remove alumina  from  the   crystal  lattice.    By-product non-framework amorphous alumina is then  selectively removed from the zeolite either by using a  blocking agent, to  prevent  removal  of  framework  aluminum during a subsequent  acid treatment, or  by using  a selective  organic  acid   extracting  agent.    The invention is also directed  to high silica  crystal-line zeolites prepared by the present process.

Title: Control of polymerization reaction
Inventor: TORMASCHY KELLY E
IPC: B01J19/18
Filed: 1990-08-22
Abstract: ABSTRACT OF THE DISCLOSURE In a polymerization reactor,  wherein particulate polymer product material is suspended in a diluent fluid thus forming a reaction slurry, and further wherein the slurry Is circulated by a pump, the flow rate of the diluent fluid introduced into the reactor is manipulated so as to prevent the polymer solids from settling out of the circulating reaction slurry and plugging the reactor.   This is accomplished by establishing control signals which typify the flow rate of diluent fluid required to:   (a) maintain a minimum velocity for the circulating reaction slurry, (b) maintain a maximum pressure head at a selected point in the reactor and (c) maintain a maximum power level supplied to the circulation pump.  The one of signals (a), (b), and (c) above, which requires the greatest flow rate of diluent fluid, is automatically selected to manipulate diluent flow.

Title: Adjustable speed ac drive system control for operation in pulse width modulation and quasi-square wave modes
Inventor: KING ROBERT D
IPC: H02M7/5387
Filed: 1990-10-18
Abstract: A polyphase AC motor drive system comprises an electric power inverter and control means which enables operation in, and allows smooth transition between, a current controlled PWM mode and a quasi-square wave mode of operation. At low motor speeds, the system operates in PWM mode. At higher speeds, above the corner point speed of the motor, the system operates in a quasi-square wave mode.      Smooth transitions between modes of operation are controlled by a microcomputer which counts the number of current chops made by a switching device in a preselected phase leg of the inverter over a time interval that varies with the desired fundamental period of the motor current. As speed increases and approaches the corner point, the number of chops decreases below a first predetermined number, and the system transitions from PWM to quasi-square wave mode. As speed decreases, the number of chops increases above a second predetermined number (larger than the first), and the system transitions back to PWM mode. A motor speed command is limited by an adjustable clamp circuit, depending upon the DC link voltage, resulting in a robust drive that is not affected by utility brownouts or line transients.

Patent CA-2037277-A1 (CA)
IPC: E21B47/04
Filed: 1991-02-28
Abstract: An echo sounding system includes an acoustic gun which is mounted to the wellhead of a borehole.  The acoustic gun produces an acoustic pulse which is transmitted down the borehole.  A tubing string is installed in the borehole and it has substantially evenly spaced collars.  Fluid is pumped from the borehole, or well, by use of a reciprocating pump driven by a pump rod extending to the surface.  The acoustic pulse produces reflections when it strikes the tubing collars and the surface of the fluid.  A microphone detects the reflections to produce a return signal. This signal is digitized and stored.  The digitized signal is processed to detect the rate of the collar reflections and the stored signal is narrowband filtered with a passband filter centered at the rate of receipt of the collars.  Each cycle of the narrowband filtered signal corresponds to one collar reflection.  In this signal, each cycle is counted, and extrapolation used when necessary to produce a collar count extending from the surface to the liquid surface.  This is multiplied by the average joint length to produce the depth to the liquid surface.  The system further detects the liquid level and displays it as a marker on the data signal. An operator can use the automatically determined marker or move it to another position.  Finally, the operator is provided with optimum operating parameters for achieving maximum production from the well.

Title: Method & apparatus for measuring oxygen concentration and its subsequent use in estimating nitrogen fixation in plants
Inventor: LAYZELL DAVID B
IPC: G01N21/25
Filed: 1991-03-18
Abstract: A non-invasive method and apparatus are described for measuring the oxygen concentration in the infected cells of the nodules of nitrogen fixing plants in the laboratory or field. In many cases, this information can be used to estimate the nitrogenase activity, and therefore the nitrogen fixation rate, in these nodules since recent studies have shown that the oxygen concentration limits and controls nitrogenase activity under most environmental conditions. Using the same apparatus, a method to measure nodule respiration and nodule oxygen permeability is also described. The nodule oxygen concentration in the infected cells of nodules is maintained at very low levels and has not been measurable previously by non-invasive techniques.      The fractional oxygenation of plant hemoglobin is measured spectroscopically using one or more modulated light sources, a number of optical fibres to convey the light to and from the nodules, a photodetector to measure the light passing through the nodule and a detection system such as a photodiode coupled to a microcomputer or a lock-in amplifier to process the output signal.

Abstract: In the case of a continuously operating mixing kneader for the thermal or chemical treatment of products in liquid, pasty and/or pulverulent state in a housing, there is arranged in this housing, running axially, a kneader shaft (20), which is equipped with disk elements (25) and kneading bars (40) and rotates about an axis of rotation (z). Said kneader shaft effects the transporting of the product in the direction of transport (x). Between the disk elements (25) there are provided kneading counter-elements (33), fixed to the housing (1), the disk elements (25) being arranged furthermore in disk planes (42) perpendicularly to the kneader shaft and forming between them free sectors, which create kneading chambers with the disk plane (42) of adjacent disk elements (25).      In this arrangement, the kneading bars (40) are intended to be arranged on a positive or negative offset line (43 or 44) in the kneading chambers between two disk planes (42). In the case of a positive offset line (43), each kneading bar (40) respectively assigned to two disk elements (25) is followed, counter to the direction of rotation (z), by a kneading bar assigned to the next two disk elements of the kneading chamber (28) following in the direction of transport (x), whereas the negative offset line (44) runs in the direction of rotation (z) and the direction of transport (x).
