Patent CA-2274330-A1 (CA)
Inventor: BATTEN JAMES BOYD
IPC: E06C7/44
Filed: 1999-06-03
Abstract: In a device to make adjustable the relative length of the side-rails of a ladder, to facilitate use on non-level supporting surfaces, a lockable, releasable, longitudinally slidable leg is attached to a side-rail by one or more bracket arrangements which freely embrace the sliding leg and provide a mounting base for attaching a lever hawing an eccentric cam that can optionally bind the sliding leg between that cam and the side-rail of a ladder. When the lever is moved to force the eccentric cam against the slidable leg until the eccentric is very slightly past it's point of highest compression, it is located in this position in it's arc around the lever fulcrum because being past the point of highest compression it tends to move on, away from that point towards a point of lower compression but is prevented from doing so because the lever handle has contacted the slidable leg also. To release this compressed locking action the operator applies force on the lever in the opposite direction to force the eccentric back past the point of highest compression and on to release the compression as desired. In this invention the strength of the operator is greatly augmented by the mechanical advantage of the lever when the lever is manipulated by simple movements in a single plane. This device is adaptable for use on many ladder designs as the bracket arrangements may be attached to side-rails of a ladder without interfering with operation of normal extension ladders while the brackets array be sized to fit smaller side-rails and may be expanded to fit larger ladder side-rails on installation by inserting appropriate spacer shims and washers between bracket parts and lever assemblies. The sliding leg may be made from material of sufficient size and strength and may be shaped so one end view would reveal a simple capital letter "L" form to allow convenient slidability along side-rails of various widths. This invention may be manufactured, installed and used without complicated machinery and highly skilled labour.

Inventor: SACHS MATTHEW E
IPC: G09B15/00
Filed: 1999-06-15
Abstract: The guitar scale and chord template is a teaching aid for students to learn where to find all of the chord shapes and scale patterns in a certain key on the guitar, (or any stringed instrument, e.g. bass), fretboard. The invention is a thin sheet of vinyl with rectangular holes cut out of it where the guitar frets lie. This sheet slides beneath the strings and is held tightly against the neck of the guitar with Velcro. The holes are placed so that the guitar frets don't touch the template. The template has dots on it, which show up underneath the strings and represent the scale tones for a certain key. (A  different template is needed for each key to be studied.) Also, the chord tones for that key are designated with the symbols R, 3, and 5 instead of the regular dots so that the student can easily find where to play the scale tones and chord tones of a certain key on the guitar. When the student is through practicing, the student can easily undo the Velcro and slide out the template leaving the guitar unaffected. Different shaped templates will be needed for use on electric guitars, classical guitars, basses, and acoustic guitars due to the different shaped necks.

Title: Flexible swage
Inventor: MILLS AUBREY C
IPC: E21B29/10
Filed: 2000-01-28
Abstract: A flexible swage improves the prior art swaging knowledge by avoiding a drawback of swage use. The swage comprises a support and a cup-shaped swage member which when engaged with one another form a swage which acts much like the prior art swage devices to reform a deformable junction. Once the reformation is complete however and the swage must be removed from the well, the swage cup disengages from the support and is allowed to deflect several thousandths of an inch, significantly reducing drag on the deformable junction while the swage device is being removed from the hole.

Title: Metal gasket
Inventor: UEDA KATSUNORI
IPC: F16J15/08
Filed: 2000-02-22
Abstract: In order to provide a metal gasket suitable for use for a flange made of synthetic resin, the metal gasket disposed between a resin flange and an aluminium flange is composed of two elastic metal plates, on each of which a half bead is formed, and which are superposed on each other to be jointed so that half beads are directed opposite to each other. Since bending in a state, where the gasket is tightened, can be suppressed to an extremely small value at a same level in the case where the flanges are tightened without gasket, it is possible to remove worsening in flatness (planarity) of the resin flange.

Title: Method and apparatus for providing reduced cost online service and adaptive targeting of advertisements
Inventor: RODRIGUEZ HERMAN
IPC: G06Q30/02
Filed: 2000-05-01
Abstract: A method and apparatus for adaptively targeting advertisements to a specific client computer from a server within a distributed data processing system is provided. As a user of the client browses the World Wide Web, the material that is downloaded to the client constitutes a datastream. At some location during the routing of the datastream, either on the server or at the client, the datastream is scanned to generate a list of keywords that are present within the datastream. The datastream may be analyzed in real-time or cached and analyzed on a delayed basis. The generated list of keywords represents a summary of the content that appears to be the focus of interest of the user. The keywords are compared against a database of advertisements, and the server selects an advertisement that matches the user's area of interest in comparison to the analysis of the user's browsing history. The selected advertisement is then inserted into the datastream to be routed to the client. In consideration for viewing targeted advertisements and to entice a Web viewer to allow the monitoring of a datastream so that targeted advertisements may be placed into the datastream, a Web viewer may receive online connection service for tree, for a reduced cost, at a premium level of service, or for other some other value, such as frequent viewer credits that may be exchanged for goods and services.

Title: Modular fuel element adaptable to different nuclear power plants with cooling channels
Inventor: BERGALLO JUAN ESTEBAN
IPC: G21C3/30
Filed: 2000-05-02
Abstract: The present invention relates to a modular nuclear fuel element, which can be adapted by an assembly system allowing it to be used in different nuclear power plants with horizontal and vertical cooling channels. The module is a cluster of parallel fuel rods mounted as circular concentric crowns and supported by a structural system. It has a single diameter fuel rod array where the ratio of the heat transfer area to the transverse rod area is higher than 330. It also has self-supporting fuel element spacer grids, which are collapsible sheaths attached to them with fewer than 13 welded end stoppers, The number of these fuel rods is higher than 43. The length of the module is the largest compatible length with the refuelling machine, to reduce the hydraulic restrictions caused by structural endings, and to be able to balance this by providing a fuel element having a larger cooling area. This will maintain the hydraulic restriction and the current total fuel mass in the channel.      The modular fuel element may contain fuel material combinations with different uranium and/or plutonium isotopic concentrations, and/or any other nuclear fuel material (actinides, nuclear poisons, fission products or fuel material coming from other nuclear reactors.      The utilisation of the fuel modules individually in the pressurised heavy water reactors with horizontal fuel channels is an application of the present invention. Another application would involve the assembling of several fuel modules in nuclear reactors with vertical fuel channels.
