Patent CA-2495113-A1 (CA)
Title: Apparatus and method for controlling adaptive circuits
Inventor: BLODGETT JAMES R
IPC: H03F1/32
Filed: 2002-08-12
Abstract: A feedforward type amplifier having a signal cancellation loop includes a cancellation node, a gain controller (C1) and a phase controller (C2). Each controller provides a discrete tap steering signal that it modulates with a discrete tracer signal that takes on a preselected sequence of values. The sequence is chosen so that the tracer signal is mutually orthogonal to each other tracer signal over a preselected period. A gain and phase adjuster (GPA1) connected to the outputs of the controllers provides a controlled gain change and phase shift in the signal cancellation loop. A detector (D1), the input of which is connected to the cancellation node and the output of which is connected to the controllers outputs a measure of the envelope of the signal at the cancellation node. After the preselected period new values for the tap steering signals are obtained by multiplying the detector output by the respective tracer signal, each over the respective preselected period, summing each resulting series of values, and changing the tap steering signals to be modulated and presented to the gain and phase adjuster in accordance with the values of the respective sums.

Title: Closed system rotary machine
Inventor: KATZ ANDRE
IPC: F04C18/08
Filed: 2003-09-04
Abstract: The invention relates to a closed system rotary machine. The inventive machine comprises an inner shaped element (1) and an outer shaped element (2) which define therebetween cavities or capsules having a variable volume (V¿1?, , V¿9?). The contact points which define the capsules (C¿1?, , C¿9?) are disposed along lines of action (CA¿1?, CA¿2?, CA¿3?) which are concurrent at junction points B<SB>N</SB> and B<SB>M</SB>, where said cavities begin and end respectively. According to the invention, the contacts (C¿2?) at points located on the tangent (T) common to both pitch circles (6, 7) are osculating elements with a shared centre of curvature which is situated at the rolling point (R) of the pitch circles (6, 7). The invention can be used to ensure that the capsules form and disappear very gradually and to facilitate the distribution of the capsules when they are forming and disappearing in order to increase the leak paths.
Patent CA-2497716-A1 (CA)
Title: Screwdriver bit locking mechanism
Inventor: FRUHM HERMANN
IPC: B25B23/00
Filed: 2005-02-18
Abstract: A bit locking mechanism for a screwdriver having a shaft with a bit chuck formed in one end of the shaft. A slot in the shaft intersects a rearward portion of the chuck. A lever is pivotally mounted in the slot, and extends parallel to the shaft. A tab on the lever's forward end has a rearward face substantially perpendicular to the lever's longitudinal axis. A spring normally biases the tab into the chuck. The locking mechanism is used with a bit having a rearward collar with a length substantially equal to the difference between (i) the distance from the lever's pivot point to the tab's rearward face, and (ii) the distance from the lever's pivot point to the chuck's rearward end. The collar's forward face is substantially perpendicular to the bit's longitudinal axis. As the bit is inserted into the chuck, the bit's rearward end slides under the lever, overcoming the spring's bias and pivoting the lever into a bit insert/release position. When the collar's forward face moves rearwardly of the tab's rearward face, the spring pivots the lever into a closed position in which the tab protrudes into the rearward end of the chuck, with the tab's rearward face latched against the bit's forward face, preventing unintended withdrawal of the bit from the chuck.

Title: Apparatus and methods for co-location and offloading of web site traffic based on traffic pattern recognition
Inventor: KING RICHARD PERVIN
IPC: H04L12/56
Filed: 2003-11-14
Abstract: Apparatus and methods for identifying traffic patterns to web sites based on templates that characterize the arrival of traffic to the web sites are provided. Based on these templates, determinations are made as to which web sites should be co-located so as to optimize resource allocation. Specifically, web sites whose templates are complimentary, i.e. a first web site having a peak in arrival traffic at time t1 and a second web site that has a trough in arrival traffic at time tl, are designated as being candidates for co-location. In addition, the present invention uses the templates identified for the traffic patterns of web sites to determine thresholds for offloading traffic to other servers. These thresholds include a first threshold at which offloading should be performed, a second threshold that takes into consideration the lead time needed to begin offloading, and a third threshold that takes into consideration a lag time needed to stop all offloading of traffic to the other servers.

Title: Fire-resistant ultra-lightweight panel with three-dimensional surface design
Inventor: DAVIS GEORGE KALOGRIDIS
IPC: B32B33/00
Filed: 2006-02-14
Abstract: The invention relates to an ultra-lightweight heat and flame resistant (or retardant) composite panel having a three-dimensional artistic design on the surface, and a method for making the lightweight heat and flame resistant composite panel. One aspect of the invention is a system and method for creating a composite panel from high performance heat and flame resistant materials, such as aramid polyamide polymers (for example, NOMEX® from DuPont) or any other fire-retardant or fire-retardant treated material, which can be bonded to another layer of fire-retardant material such as paper, fabric, honeycomb or foam. The fire-retardant materials can be bonded by a welding machine such as an ultrasonic machine, or attached by a thermoplastic, thermoset, thermobond or other fire resistant adhesive. The thickness of the finished composite may be around 1/16~1/4 inch. The composite can then be decorated, and carved (or embossed) with or without inserting a fire-retardant material between the layers prior to carving to give a three-dimensional decorative surface. The steps of decorating and carving may be performed in either sequence-coloring followed by carving, or carving followed by coloring. Alternatively, one or more layers may be printed prior to forming the composite. A clear finish with fire retardant agent is then placed on the surface of the composite.

Abstract: An improved golf club with controllable dynamic characteristics is provided with a weighing cylinder of controllable weight rigidly secured within the elongated cavity of the club head. The chamber is dynamically weighted by providing a volume of liquid-like material such as mercury within it and has the dynamically weighted mercury capsule protruding into the club head. The dynamically weighted cylinder when filled with the appropriate volume of material, functions to increase the head weight and dynamic mass upon impact with the golf ball. When the golf club is swung downwards from the top of its back swing, the movement of the liquid-like material within the dynamically weighted cylinder in the direction of swing provides added momentum which produces increased force of impact at the point where driving contact is made between the face of the club and the ball.
