Patent CA-2072919-A1 (CA)
Inventor: ELLINGSEN OLAV
IPC: E21B43/24
Filed: 1992-07-02
Abstract: This invention refers to a process as well as to the equipment required to enhance the recovery of petroleum from onshore and offshore reservoirs.   The pro-cess includes the simultaneous stimulation of the forma-tion by means of elastic sound waves, created by a sonic source installed at the oil well so that the elastic sonic waves which are superimposed reduce the adherence forces in the layer between oil/water and the rock forma-tion, and by means of the oscillating electrical stimula-tion of the same layer, as from the same wells subject to sonic treatment, where the electricity heats the formation by means of resistive heating, and thus increases the pressure, eliminating, thus, the surface tensions between the faces of the fluid as a consequence of the oscillatory action of the ions in the surfaces of the fluid and, in addition, reducing the viscosity of the fluids.   The pro-cess is achieved as the petroleum is produced in the wells thus treated, and the flow of petroleum acts then as a cooling agent which removes the heat released by the well area and thus allows a larger input of energy than in any other method known so far.

Title: Method of and apparatus for packaging a beverage in a container
Inventor: JONES MICHAEL E
IPC: B67C3/22
Filed: 1992-10-07
Abstract: A method of and apparatus for packaging a beverage in a container 1 having a primary chamber and a relatively smaller secondary chamber which communicates with the primary chamber by way of a restricted orifice has the exterior of the container maintained at atmospheric pressure. The container such as a can 1 to be charged with beer is engaged within a filling head block 24 through nozzles 35 from which beer 9 is to flow into the can 1 from a bowl 8.        Prior to filling the can 1 is pressurised through the head 24 with nitrogen gas to greater than atmospheric pressure and subsequently evacuated to atmospheric pressure by control of valves 32, 33. Such pressurisation and evacuation may be repeated sequentially to dilute the atmospheric oxygen content within the primary and secondary chambers of the can 1 where the oxygen has negligible effect on the beer which is to be sold in the can. A gas exchange conduit 40 extends between the bowl headspace 12 and the can 1. Conduit 40 has a port 41 of a gas control valve 55 which port 41 is closable by movement of lever 60.        A beer flow valve 37/46 controls flow of beer 9 from the bowl through nozzles 35. During pressurisation of the can 1 with nitrogen gas the lever 60 is adjusted to maintain closed the part 41 of the gas flow valve and the beer flow valve 37/46 to ensure that high pressure gas in the can 1 cannot flow by way of the gas exchange conduit 40 into the bowl headspace 12 and again flow through the nozzles 35 into the beer 9 in the bowl 8.

Title: Drill string jarring and bumping tool
Inventor: ANDERSON CLIFFORD J
IPC: E21B31/107
Filed: 1993-03-19
Abstract: A jarring and bumping tool is provided, having a mandrel telescopically received within a barrel for relative longitudinal movement. Upper and lower seals form an oil-containing annular space therebetween. The mandrel carries a free-floating annular primary piston which sealably engages a reduced-diameter piston fitting section of the barrel when passing therethrough. The mandrel also carries a secondary cylinder assembly with a transverse top wall and a downwardly extending annular secondary cylinder beneath the primary piston, forming a piston chamber between the mandrel and secondary cylinder assembly. The mandrel also carries a spring which biases a free-floating annular secondary piston upwards into the piston chamber. A port through the top wall of the cylindrical member provides fluid communication between the annular space and the piston chamber. Thus, when the mandrel is pulled upwards the primary piston seals against the piston fitting section, oil in the annular space is compressed and forced through the port and into the piston chamber against the secondary piston to compress the spring, and the drill string is stretched. When the primary piston clears the piston fitting section, fluid moves rapidly around the primary piston, the mandrel extends, and impact faces connect to deliver a jarring stroke upwards.

Title: Electrical fault detector
Inventor: SPAEDER WILLIAM J
IPC: H04B3/46
Filed: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE     Imbalances between currents to and from a remote point are detected by passing the outgoing currents and the return current through different, oppositely-oriented coils on a saturable core, and an excitation current is applied to another coil in the same core sufficient to drive the core into saturation in at least one direction.  When the outgoing and return currents are the same, the excitation produces successive voltage pulses of the same durations, as measured by an up-down counter; if an imbalance is present, the remainder in the up-down counter shows this.  To detect excessively high imbalances, which might place the core always in saturation, another counter preferably senses the sum of the widths of successive pulses, and indicates an imbalance if this sum falls below a preselected threshold.

Filed: 1993-06-29
Abstract: ABSTRACT            The apparatus assists a person in drawing marks that can stimulate the imagination and can be elaborated upon to develop an original drawing. The apparatus consists of a substantially cylindrical shape that is upright, open-ended and hollow, having a panel fixed across its upper end, the panel having an orifice in its center area. The apparatus is used by inserting the drawing tip of a drawing marker through the orifice of the panel; positioning the drawing marker,now projecting from both sides of the orifice, so that its drawing tip is essentially even with the open bottom end of the cylindrical shape; placing the apparatus with its open bottom end downward upon a drawing surface so that the tip of the drawing marker is in contact with the drawing surface; grasping and manipulatingthe entire apparatus with one hand while the other hand manipulates the drawing marker; moving the drawing marker and the apparatus either simultaneously or alternately and according to patterns of personal choice thus applying marks to the drawing surface. The resulting marks cannot be seen when applied and therefore cannot be totally controlled. They are in effect fresh and spontaneousin appearance. The quality of these marks make them a possible source of inspiration for the artist's imagination and from them he or she can elaborate an original drawing.

Title: Bicyclette zelos
Inventor: DEZIEL REJEAN
IPC: B62K3/00
Filed: 1993-08-25
Abstract: Précis L'invention de la bicyclette, résultat évolutif étalé sur une centaine d'années, a sa naissance homologuée vers l'année 1880. Sa métamorphose témoigne des nombreux et profonds changements de perception et de mode de vie. Depuis cette date, ce véhicule n'a subi aucune modification significative. La bicyclette a gardé sa place au sein des moeurs citadines et rurales, accordant à travers sa simplicité la possibilité du défi et du dépassement. La prospection dans ce domaine indique des possibilités intéressantes en ce qui à trait à l'efficacité de l'appareil. Mais la notion d'efficacité doit être abordée de façon à comprendre comment ce véhicule s'intègre à son milieu, principalement à la circulation routière; de plus, son efficience est pour l'essentiel à l'élaboration et non à la complexification. ? l'usage répété, la bicyclette provoque des fatigues exagérées aux bras, aux épaules et au cou, limitant ainsi son utilisation efficace et agréable à long terme. La solution est au redressement de la position du cycliste et à son adossement afin d'augmenter le confort et la puissance de propulsion du véhicule. La nouvelle posture oblige à une refonte du modèle qui ne peut pourtant pas s'écarter des exigences de la conduite routière. Le résultat s'associe particulière-ment aux surfaces carossables des routes et à la souplesse de ses pneus.
