Patent CA-2451438-A1 (CA)
Inventor: ROBERTS JEFFREY B
IPC: H02H1/00
Filed: 2002-06-24
Abstract: A delta filter for use in a protective relay which includes an input circuit (50) for receiving phasor signals (V) representative of electrical signal quantities on the power line. A difference value, if any, is determined between the phasor signals (V) at a present time and the phasor signals at a past point in time (reference phasor 1), the delay typically being one cycle.  A first incremental output value (delta V1) is produced if there is a difference. When power line disturbance is first noted by the recognition of a first incremental output value, the phasor signal value at the beginning of the disturbance is stored (54) and then used as a reference value (reference phasor 2) for comparison with subsequent present time phasor signals to determine continuing change in power system condition.

Title: Apparatus and method for photocatalytic and thermocatalytic pollution control
Inventor: TABATABAIE-RAISSI ALI
IPC: B01J8/00
Filed: 1999-04-08
Abstract: A new method for design and scale-up of photocatalytic and thermocatalytic processes is disclosed. The method is based on optimizing photoprocess energetics by decoupling of the process energy efficiency from the DRE for target contaminants. The technique is applicable to both low- and high-flux photoreactor design and scale-up. The low-flux method is based on the implementation of natural biopolymeric and other low-pressure drop media support for titanium dioxide and other band-gap photocatalysts. The high-flux method is based on the implementation of multifunctional metal oxide aerogels and other media in conjunction with a novel rotating fluidized particle bed reactor.

Title: System and method for removing contaminants from liquid
Inventor: MORSE WADE O
IPC: B01D19/00
Filed: 2002-06-25
Abstract: A method for removing contaminants from a liquid includes filtering objects of a relatively large dimension. The liquid is then mixed with additives to adjust the chemistry of the liquid. The liquid is pressurized a nd directed through a gasification device to dissolve gas into the liquid. This is accomplished by directing the liquid into an inlet of a hydrocyclone of the gasification device, directing the liquid exiting the hydrocyclone upwards t o remove large bubbles, and removing liquid containing dissolved gas from a bottom portion of a vessel of the gasification device. The pressure of the liquid is then reduced and the liquid is introduced into a separation tank, and the contaminants are removed from the liquid by stratification. The treated water is removed from the separation tank, and sludge formed by skimming flocs from a liquid surface of the tank is subjected to a dewatering process .

Abstract: Display location calculation means and methods for calculating a display location are disclosed. It has become common for users to indicate a point on a display in order to communicate with a machine. It is therefore necessary to be able to calculate the location on the display that is being indicated by the user. A display generator (123) is arranged in operation to generate a display in response to display data generated by a machine (111). A camera operable to generate image data representing at least part of the scene within the field of view of the camera (which part, includes at least a portion of the display) is carried in a pointer device (103). Computation means (111, 113, 115) are arranged in operation to receive the image data and the display data and to calculate from these data sets the position and/or orientation of the pointer device (103) relative to the display. A display location can then be calculated from the calculated position and/or orientation.

Abstract: Driver's licenses and other security documents include one or more machine-readable features, each conveying plural bits of information. These features are used in a variety of ways to increase security, and/or to enhance functionality. In one embodiment, data encoded on a driver's license is used at airport check-in, to link to a state DMV database and obtain information by which the document, and its custodian, can be authenticated. In like fashion, a license can be used to authenticate a bearer and/or his/her age prior to the sale of alcohol or tobacco products. In other embodiments, different elements of a driver's license (e.g., the substrate, photo, text data, and machine-readable data) are logically bound together (e.g., interlinked through payloads conveyed by different machine-readable features) as a deterrent against counterfeiting. Driver's licenses can be similarly logically bound to personal checks and other documents. Many other arrangements are also disclosed.

Patent CA-2483606-A1 (CA)
Inventor: JACQUES ANDRE
IPC: A47C7/00
Filed: 2004-10-13
Abstract: Disadvantages of a conventional chair (table etc...): the pressure per square centimetre on the floor is high, we have the tendency to drag the chair on the floor (which is noisy) to move it by rising only slightly; the floor becomes damaged. The pivoting base eliminates these disadvantages and brings additional advantages. The chair legs (1) are inserted at the extremity of the 4 parts (9). Two circular bases (3 and 4) are tied together by a rotation joint located at the center of the bases. The top base (3) ROTATES on the bottom base (4) (which does not rotate) thanks to ball bearings (5) arranged in a circle between the two bases (along the circumference).   This allows the seated person to rotate towards another person without the risk of damaging the floor (2) and quietly. The feature of the bottom base includes 3 wheels (6) arranged in a triangle under the base. These wheels are equipped with compression springs (7). When no one is seated, it is easy to move the chair (without noise) thanks to the wheels that have come out. When a person sits down, the wheels enter the lower base. The lower base rests on the floor, with a very low pressure per square centimetre since the area of the circular base is very large, in contrast to the 4 legs of the chair.  Therefore, no damage to the floor and no noise.

Inventor: JONES DAVID MICHAEL
IPC: F16F1/00
Filed: 2003-05-06
Abstract: The invention provides an automatic balancing device for counterbalancing an out-of-balance mass present in a rotating body. The automatic balancing device (50) comprises a chamber (56) having an outer wall (54) and an axis (18), first and second counterbalancing masses (80a, 80b) constrained to move freely in a circular path about the axis (18) and within the chamber (56), and a viscous fluid (60) provided in the chamber (56) so as to provide viscous coupling between the outer wall (54) of the chamber (56) and each of the counterbalancing masses (80a, 80b). The counterbalancing masses (80a, 80b) are adapted and/or arranged such that, in use, the first counterbalancing mass (80a) leads the second counterbalancing mass (80b). Constraining means (90a, 92a, 94a, 94b) are provided so as to prevent the first counterbalancing mass (80a) from leading the second counterbalancing mass (80b) by more than substantially 180~ when the device is in use. This arrangement minimises the excursion of the rotating body at the critical speed. Such an arrangement has application particularly in the field of washing machines in which the position and size of the out-of-balance mass is unpredictable and there is a need to increase the speed of rotation of the body from a relatively low speed to a relatively high speed.
