Title: Compositions and a method of improving the transfer efficiency of sprayed paints
Inventor: MEYER VICTOR E
IPC: C08L101/00
Filed: 1995-01-31
Abstract: This invention deals with novel compositions of matter and a novel method for improving the transfer efficiency of solvent-based paints that are sprayed onto surfaces, wherein current practice normally results in significant loss of paint to the environment rather than deposition on the surface. Such novel compositions are ultra-high molecular weight acrylate polymers solubilized in a solvent-based acrylate paint.

Title: Press/heating platen for continuously operating presses
Inventor: BIELFELDT FRIEDRICH B
IPC: B30B15/06
Filed: 1995-02-15
Abstract: The invention relates to a press/heating platen for continuously operating presses used in the production of particle boards or like material. Such presses have a flexible endless steel belt for transmitting pressure to the material and for moving the material through the press. The belt is guided by driving drums and reversing drums around upper and lower press beams and are supported with an adjustable press nip against a press/heating platen on the press beams by rollers arranged with their axes transverse to the running direction of the belt. The press/heating platen is adjustable by means of cylinder/piston arrangements disposed in rows longitudinally and transversely to the longitudinal axis of the press. In the invention, fluted grooves are moulded into the rear sides of the press/heating platens, longitudinally to the pressing zone, and also honeycombed grooves are moulded in the rear sides transversely to the pressing zone between the actuator rows. This profile provides an improved flexible two-dimensional deformation while permitting larger support spacings.

Title: Viral amplification of recombinant messenger rna in transgenic plants
Inventor: TURPEN THOMAS H
IPC: C12N15/12
Filed: 1993-12-29
Abstract: A novel method of over expressing genes in plants is provided.  This method is based on the RNA amplification properties of plus strand RNA viruses of plants.  A chimeric multicistronic gene is constructed containing a plant promoter, viral replication origins, a viral movement protein gene, and one or more foreign genes under control of viral subgenomic promoters.          Plants containing one or more of these recombinant RNA transcripts are inoculated with helper virus.  In the presence of helper virus, recombinant transcripts are replicated producing high levels of foreign gene RNA.          Sequences are provided for the high level expression of the enzyme chloramphenicol acetyltransferase in tobacco plants by replicon RNA amplification with helper viruses and movement protein genes derived from the tobamovirus group.
Patent CA-2153108-A1 (CA)
Title: Semiconductor-controlled operating circuit for one or more low-pressur discharge lamps, typically fluorescent lamps
Inventor: RUDOLPH BERND
IPC: H05B41/295
Filed: 1995-06-30
Abstract: To operate one or more serially connected low-pressure discharge lamps, typically fluorescent lamps, a preheating circuit is provided to preheat the electrodes of the lamps (E1, E2, E3, E4), which changes from low-impedance to high-impedance state after the lamps have been preheated by controlling a semiconductor switch (Q3) in the heating circuit.  In accordance with the invention, to eliminate reliance on the resistances of the lamp filaments themselves, which are subject to variation from lamp-to-lamp due to manufacturing tolerances, and later on, to changes due to aging of the lamp, and to provide for reliable switching of the semiconductor switch, a sensing impedance element (Z), which may be an ohmic resistor or a capacitor (Z', Z"), is serially connected to the switching path of the semiconductor switch (Q3) which, typically, is a field effect transistor (FET).  The voltage drop across the series circuit formed by the impedance element (Z, Z', Z") and the semiconductor switch (Q3) is set by suitable dimensioning of the impedance element, to be sufficient to retain the main switching path of the semiconductor switch in low-impedance state when it carries full heater current, that is, is already in low-impedance state. To change over to high-impedance state, control signals to the semiconductor switch are removed, for example by shunting a resistor (R2) in a voltage divider, thus turning the semiconductor switch (Q3) OFF.

Title: Mode suppression in fluid meter conduits
Inventor: BIGNELL NOEL
IPC: G01F1/66
Filed: 1994-03-07
Abstract: A fluid flow measurement arrangement is disclosed where the effects of high-order acoustic modes are suppressed in ultrasonic flow measurement. Ultrasonic transducers (2, 3) are arranged in a duct (4, 13) configured to carry a fluid. Ultrasonic signals between the transducers (2, 3) travel in a plurality of high order modes having velocities slower than a fundamental mode whose time of flight is desired to be determined with accuracy. A measurement portion between the transducers is adapted to suppress the effects of the non-fundamental modes, notably to suppress their propagation. Embodiments disclosed to achieve this suppression include inserting fluid dynamically configured obstructions (10; 11,12) (fig. 6, Fig. 7) within the measurement portion, and/or making the cross section of the measurement portion non-uniform (Figs. 15A, 15B).

Title: Adaptive noise-predictive partial-response equalization for channels with spectral nulls
Inventor: CHEVILLAT PIERRE
IPC: G11B20/10
Filed: 1993-06-14
Abstract: The present application makes use of a novel adaptive noise-predictive partial-response equalization scheme for channels (30) exhibiting spectral nulls and/or near nulls. The noise-predictive partial response (PR) equalizer employed in the different embodiments of the present invention consists of a linear PR equalizer (32) which shapes the channel response to a predetermined partial-response function, followed by a linear predictor. This scheme modifies the output sequence of said linear partial-response equalizer (32) by whitening the total distortion, i.e. by whitening the noise components and the residual interference components at said linear PR equalizer output, thereby achieving the best possible signal-to-noise ratio (SNR) before detection.
Patent CA-2160176-A1 (CA)
Title: Production logging mechanism for across-the-borehole measurement
Inventor: ROESNER RAYMOND E
IPC: E21B47/10
Filed: 1995-10-10
Abstract: A production logging tool for use in deviated wellbores is provided having an elongate tool body and an elongate sensor probe that is capable of lateral movement relative to the tool body. The sensor probe is connected to the tool body by a mechanism serving to deploy the sensor probe such that it is oriented across the wellbore. The tool body has a defined weight and the probe has a weight less than the defined weight, thus causing gravity induced orientation of the sensor probe so as to extend from top to bottom of the fluid passage for sensing all phases of the fluid present therein. The sensor probe is typically of elongate configuration and may support a single elongate sensor or a plurality of independent similar or dissimilar sensors arranged in spaced relation along the length of the probe. Orientation of the sensor probe across the borehole is accomplished mechanically by coil or leaf springs or by a hydraulically or pneumatically powered mechanism or by an electric motor driven mechanism.

Title: Quill shafted pellet mill
Inventor: BITTNER OSZKAR
IPC: B29B9/06
Filed: 1995-12-22
Abstract: The  present  invention  employs  a  main  shaft cantilevered from a frame.   A die holder is disposed around the outside of the shaft, and in the preferred embodiment rotates by the use of adjustable tapered roller bearings around the shaft.   Fixed to the die holder is a die, and the die and die holder define a pelletizing chamber.  The shaft supports a roller frame with a plurality of rollers within the pelletizing chamber.   The resulting construction is a pelletizer shaft support structure that uses only a single set of bearings.  In the preferred embodiment, the main shaft is comprised of an inner shaft and an outer shaft.  The inner shaft is located coaxially within the outer shaft and supported within the outer shaft by means of static bushings.  The roller frame and rollers are mounted to the inner shaft.  The inner shaft and the outer shaft are both fixed to the frame structure.  The outer shaft is fixed in a permanent manner while the inner shaft is fixed to the frame by use of a shear pin to allow rotation  under  emergency  circumstances.     During operation of the mill,  should binding of the roller mechanism in relation to the die result in undue torque being placed upon the inner shaft, the shear pin will shear and allow the inner shaft and the outer shaft to rotate relative to each other to protect the mechanism from further damage.
