Title: Screen-printable or dispensable active brazing pastes and process for producing the same
Inventor: HEGNER FRANK
IPC: B23K35/14
Filed: 1999-09-21
Granted: 2007-09-18
Abstract: These active brazing pastes satisfy the requirements for screen printing or dispensing particularly well and are well suited for brazing one aluminum oxide ceramic body to another one or to a metal body. This can be done by means of respective regions of brazing paste applied by screen printing to the ceramic bodies, with the coverage of one region matching the coverage of the other region or by in-serting the metal body into a hole in the ceramic body and using a pad of brazing paste applied to the ceramic body and to the metal body by dispensing. The printable paste comprises as the active brazing material a hydrogenated powder of a Zr/Ni/Ti alloy or a Zr/Fe/Ti/Be alloy and as an organic vehicle poly(butyl-methyl methacrylate) or poly (n--decyl methacrylate) as the polymer and the camphor ketal of 2,2,4-trime-thylpentane-1,3-diol and/or 5-nonyl-methyl ether as the solvent for the polymer. The dispensable paste comprises as the active brazing material the same powder and as the organic vehicle a mixture of poly (butylmethyl methacrylate) dissolved in the camphor ketal of 2,2, 4-tri-methylpentane-1,3-diol as a first solvent, as a first com-ponent of the mixture and poly(butylmethacrylate) dissolved in 5-nonyl methyl ether, as a second solvent, as a second component of the mixture.

Granted: 2002-11-26
Abstract: An adapter for increasing the frictional force generated by a spacer interposed between a pair of items. The spacer defining a pair of opposed load bearing surfaces and a pair of spacing surfaces. The adapter includes a relatively flat plate defining a pair of plate surfaces, a pair of opposed contacting edges and a pair of spacing edges. A fixing component is provided for fixing the plate to one of the spacing surfaces of the spacer. A set of friction increasing teeth extend from at least one of the contacting edges for increasing the friction coefficient of the contacting edge with an item. The plate is configured and sized so that the friction enhancing teeth protrude from one of the load bearing surfaces when the plate is mounted on the spacer. In one embodiment, the adapter also includes an auxiliary friction enhancing segment for enhancing the friction between the adapter and contacting items. The auxiliary friction enhancing segment includes an auxiliary section having a generally "L" shaped configuration and extending substantially perpendicularly from one of the contacting edges so that the adapter with its auxiliary section has a generally "U" shaped cross sectional configuration.  The "L" shaped auxiliary section defines a first auxiliary segment extending substantially perpendicularly from one of thecontacting edges. The first auxiliary segment is configured and sized so as to override one of the load bearing surfaces.The first auxiliary segment bends integrally and substantially perpendicularly into a second auxiliary segment. The second auxiliary segment defines a pair of second auxiliary segment contacting edges. At least one of the second auxiliary segment contacting edges is provided with corresponding friction teeth extending therefrom. In yet another embodiment, an abutment plate extends substantially perpendicularly from the first auxilliary segment.

Title: Slanted well enhanced extraction process for the recovery of heavy oil and bitumen using heat and solvent
Inventor: THIMM LAURA
IPC: E21B17/18
Filed: 2000-04-10
Granted: 2008-02-12
Abstract: A technique for the in-situ recovery of petroleum hydrocarbons from an underground formation uses a combination of heat and vaporized solvents comprising lighter hydrocarbons. Liquid solvent is injected through a substantially slanted well, placed near the base of the reservoir, and is vaporized in-situ by applying heat through an indirect heating system placed inside the slanted well. Hot solvent vapor rises inside the reservoir, contacts the cold viscous hydrocarbons, condenses, dissolves and diffuses into the hydrocarbon in the reservoir. As a result, the viscous hydrocarbon is diluted to a lower viscosity fluid, which drains to the slanted well and is thereafter produced to the surface.

Title: Method of sorting and categorizing seed
Inventor: MAILLOUX LOUIS
IPC: B07B13/00
Filed: 1998-10-30
Granted: 2004-06-15
Abstract: A method of sorting and categorizing seed departs from the traditional method of sorting based primarily on size of the seeds and instead sorts primarily on the basis of shape of the seeds. Sorted categories based primarily on shape can reduce the number of categories of the same type of seed that need to be packaged and inventoried. It simplifies warehousing, selection and planting of the sad. Optionally, the method can include sorting a substantial portion of a type of seed primarily by shape and sorting ai least a portion of the remainder of the seed by traditional methods which also include size as a factor.

Patent CA-2313710-C (CA)
Inventor: ELKIN JERRY
IPC: B41J2/14
Filed: 2000-07-11
Granted: 2004-02-17
Abstract: A droplet emitter with an array of droplet emitting devices constructed such that a flowing liquid used create the droplets can flow through the droplet emitter at higher flow rates. The higher flow rates prevent excess heat absorption during the droplet emission process and allow for excess heat generated by control electronics to be transferred to the flowing liquid after droplet emission but before it leaves the droplet emitter. This prevents excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.

Filed: 2001-10-01
Granted: 2005-05-24
Abstract: A mobile communication base station determines the oncoming direction of a radio wave with a simple arrangement and transmits a narrow angle beam in this direction. Received signals from a pair of wide angle beam antennae having an equal configuration and a common orientation and which are located close to each other are fed to a direction finder receiver and a communication receiver. By utilizing the fact that the both received signals have a coincident amplitude, a phase difference between the received signals is detected. The oncoming direction of the received radio wave (or the direction of a mobile station) is determined on the basis of the phase difference. A beam switcher is controlled so as to connect a transmitter to a narrow angle beam antenna which is directed in the oncoming direction thus determined.
