Title: Perforation cleaning tools
Inventor: FACTEAU DAVID M
IPC: E21B28/00
Filed: 1993-06-08
Abstract: ABSTRACT OF THE DISCLOSURE In accordance with illustrative embodiments of the present invention, a well perforation cleaning tool includes a fluidic oscillator that creates pressure pulsations which induce cyclical stresses in the walls of the perforations and causes damaged skins thereon to disintegrate in order to improve the productivity of the well. The output passages of one embodiment of the fluidic oscillator are connected to respective internal storage cavities and each cavity is communicated with the annulus by a pair of outlet passages. In other embodiments, relatively short length external cavities communicate with the output passages to provide means by which the pressure pulsations are conveyed to the well annulus. Cylindrical filter tubes having a plurality of sets of axially spaced slots are adjustably mounted at the upper and lower ends of the tool may, if desired, be used to provide resistances which substantially confine the pressure pulsations to the immediate vicinity of the tool body. Both tubing conveyed and coil tubing conveyed tools are disclosed.

Title: Non-impact printing of business forms from continuous webs having adhesive coatings
Inventor: BAXTER GEORGE
IPC: B42C3/00
Filed: 1993-10-07
Abstract: ABSTRACT OF THE DISCLOSURE    In a method for producing composite carbonless copy business forms using non-impact printers, a CFB web having segmented glue lines across the width of both sides of the web.  These glue lines adhere the CFB web to adjacent upper and lower CF and CB webs to seal together a business form.  The glue lines on both sides of the CFB web are segmented such that the adhesive on the front of the web is laterally staggered from the adhesive on the back of the web. The staggering of the glue line ensures that the adhesive on the front of the web does not adhere to the adhesive on the back when the web is in a roll. Alternatively, the glue line on the CFB web is replaced with a line of holes that align with the glue lines on the CF and CB webs when the webs are registered together.

Title: Reagents containing a nonspecific binding blocker in ion-capture binding assays
Inventor: ADAMCZYK JANINA
IPC: G01N33/544
Filed: 1992-04-10
Abstract: The present invention includes novel assays and reagents using a capture reagent, involving a specific binding member attached to a polymeric anionic substance, and a solid phase material containing a capture or reaction zone including a polymeric cationic substance. A test sample suspected of containing the analyte of interest may be contacted with the capture reagent to form a charged capture reagent/analyte complex. The complex is then contacted to the oppositely charged solid phase to attract, attach, and immobilize the capture reagent/analyte complex. With an appropriate indicator reagent, sandwich, competitive and indirect assays can be performed. Preferably, the indicator reagent includes a nonspecific binding blocker to reduce the nonspecific binding between the indicator reagent and the solid phase, without interfering with the reaction between the capture reagent and the solid phase.  Suitable nonspecific binding blockers include unbound or free polyanionic materials such as dextran sulfate, heparin, carboxymethyl dextran, carboxymethyl cellulose, pentosan polysulfate, inositol hexasulfate or .beta.-cyclodextrin sulfate.

Abstract: ABSTRACT            A process and apparatus are provided for assembling two, mating, threaded containers.  The threaded end of the first container is disposed in the threaded port of the second container.  The second container is clamped to prevent rotation of the second container.  A cam is rotated to engage a torque-applying assembly to produce relative movement between the clamp assembly and the torque-applying assembly.  This effects sequential engagement and disengagement of the torque-applying assembly and the first container.  The torque-applying assembly is rotated relative to the clamp assembly while engaged with the first container to effect threaded engagement of the containers.

Patent CA-2116469-A1 (CA)
Title: Sensing motor speed and rotation direction
Inventor: PORTER RANDY D
IPC: G01P13/04
Filed: 1994-02-25
Abstract: ABSTRACT OF THE DISCLOSURE       The present invention features a method and an apparatus for sensing the speed and the direction of rotation of a motor.  The apparatus of the invention has a timing wheel disk that is attached to the rotational shaft of a motor and has a number of slots.  Opposite the timing wheel are mounted two spaced-together proximity sensors that are a given or a fixed distance apart.  The sensors are spaced to read within each slot of the disk at any given point during in the rotation of the timing wheel.  When the sensors detect the edges of each slot of the rotating wheel, signals are generated.  The sensors respectively define sensing channels A and B.  A microcontroller contains a logic program that calculates the motor's speed and direction.  Speed is determined by measuring the time that it takes for a point (the edge of a rotating disk's slot) to travel across both sensors.  Direction is determined by storing the logic level of the first sensor (channel A) while a generated exclusive OR signal is high, and then analyzing the level of channel A when the exclusive OR is low.  Channel A changes logic states over the exclusive OR period when the motor is rotating clockwise; it remains at the same logic state over the exclusive OR period when the motor is rotating counterclockwise.  The invention requires no coupling or interface between the sensors.  No moving parts are required by this invention, since the timing wheel is mounted directly upon the motor shaft, and the sensors are fixedly mounted adjacent the timing wheel on the brake drum, which requires no special bracketing.
Patent CA-2117055-A1 (CA)
Inventor: SCHNUR GERALD
IPC: B01D19/00
Filed: 1992-08-17
Abstract: The invention relates to a process for separating gaseous components from pourable media. The main feature of the invention is that regions of underpressure are formed by relative movement between the media and a body arranged therein owing to the latter's shape and that the gas collecting in said underpressure regions is evacuated via the interior of the body. A device for separating gaseous components from pourable media is primarily distinguished in that it is designed as a device for generating a relative movement between the media and a body (1) arranged therein, said body being, in particular, arranged to rotate and having a contour which produces underpressure regions (8) on the surface of the body during this relative movement and the body (1) has at least one inlet (5) around the underpressure regions (8) which communicates with a gas outlet inside the body to remove the separated gas. The invention also relates to an installation using the device of the invention.
