Patent CA-2393178-A1 (CA)
Inventor: HOLT ANDREW J
IPC: B01D35/18
Filed: 2002-07-11
Abstract: The present invention provides a convenient way to filter water in a body of water. The invention combines an encloseable container with an internal pump producing cyclonic action, with two different types of filters. One type of filtering consists of layers of varied porosity, one layer filtering only very fine debris, while the other layers blocking progressively large debris. The other type of filtering involves stacked discs placed to aid in further filtering of the water in the chamber of the cylinder. Water flows around the bottom disc, through holes in the second disc, and around the third disc before approaching the stacked filters of varied porosity. An internal ultra-violet light helps control algae in the water.

Abstract: The invention relates to a device for producing a pipe coupling (1) at two pipe ends (4). The objective of the invention is to produce a pressure-tight pipe connection by applying axial pressure, thereby guaranteeing maximum universality regarding the specifications of the quality of the pipes that are tio be connected. Said device for producing a pressure-tight pipe coupling with at least one pipe end comprises a bushing-type, rotationally symmetric base body. The base body (2) is provided with at least one essentially cylindrical inner chamber, having toothed elements (6,7) in order to receive the pipe end. The toothed elements are displaced radially into the pipe end arranged in the inner chamber by means of a pressing device (6) which impinges upon the outer surface of the base body. A pressing device (10) consisting of a shaping ring and a corresponding pair of shaping rings (12,13) guarantee that the radial displacement potential is realized in the form of a radial displacement, resulting in significantly lower pressing power.

Title: Earthen liner with clay seam cover
Inventor: MATHIESON MICHAEL C
IPC: D06H5/00
Filed: 2000-10-16
Abstract: A geosynthetic liner (10) may be formed of sheets (12) of substantially liquid impermeable synthetic material such as high density polyethylene. The adjacent edges (27, 29) of adjacent sheets (12) may be lapped over one another to form a lapped joint (28). The lapped joint (28) may be covered by a relatively narrow seam cover (22) which seals the region between the two sheets (12). The cover (22) may be formed of a geomembrane layer (26) over a clay layer (24). The clay layer (24) may be formed of particles of bentonite which are adhesively secured to the geomembrane layer (26). Thus, the geomembrane liner seam may be sealed by simply unrolling the cover (22) over the lapped joint (28) and covering the sheets (12) and the cover (22) with a layer of overburden (14).

Abstract: -11- A chamber is formed in the upper end of a brush saw cutting head housing. The brush saw cutting element drive spindle's upper end projects into the chamber. The drive spindle's lower end projects beneath the housing and is drivingly couplable to the cutting element. A disc is mounted against the underside of the cutting element. A cavity is formed in the disc. At least one channel extends through the disc, between the cavity and the disc's external rim. An aperture extends through the drive spindle, between the chamber and the cavity. Herbi- cide supplied to the chamber flows from the chamber, through the drive spindle aperture, into the cavity.

Abstract: Method and apparatus for improving the efficiency and the dynamic range of a power amplifier operated with signals having a large peak-to-average ratio. A  reference level is determined, above which at least a portion of the magnitude of an input signal being a modulated signal that is input to the power amplifier, or a baseband waveform that is used to generate the modulated signal, is defined as an excess input signal. The magnitude of the input signal is continuously sampled, for detecting an excess input signal. A lower level of operating voltage is supplied to the power amplifier, if no excess input signal is detected. The lower level of operating voltage is sufficient to effectively amplify input signals having a magnitude below the reference level. A higher level of operating voltage is supplied to the power amplifier, whenever an excess input signal is detected. The higher level of operating voltage is sufficient to effectively amplify input signals having a magnitude above the reference level.

Filed: 2002-09-11
Abstract: The present invention provides a RF wireless remote-control brightness-adjustable energy-saving lamp, which comprises a brightness-adjustable energy-saving lamp and a RF remote-control module. The brightness-adjustable energy-saving lamp has a RF wireless receiver circuit therein to receive a remote-control signal and transmit it to a CPU. The CPU is used to discriminate the remote-control signal, convert it into a PWM signal, and output the PWM signal to a pulse-to-DC-voltage-level output circuit. The pulse-to-DC-voltage-level output circuit is used to convert the PWM signal into a DC voltage level. A VCO circuit connected to a starter power source circuit and a lamp tube lighting driving circuit is also provided. The lamp tube lighting driving circuit is connected to a lamp tube. The VCO circuit is used to drive the lamp tube lighting driving circuit according to the DC voltage level for adjusting the luminescent brightness of the lamp tube. The RF remote-control module can learn the internal code of the brightness-adjustable energy-saving lamp and transmit out a remote-control signal to the brightness-adjustable energy-saving lamp through pressing a key. The present invention has the advantages of remotely adjusting the brightness of a lamp and turning on and off a lamp.

IPC: H04M3/523
Filed: 2002-01-24
Abstract: A tiered service model for a digital multimedia contact center assigns an entering contact to an initial service tier based on routing criteria for the contact and may escalate or de-escalate the contact to a different service tier if the routing criteria changes. The routing criteria is initially determined based on a media type associated with the contact. The digital multimedia contact center contains a set of media routers, each of which passes a contact of a particular media type to a workflow engine which executes workflows to direct the processing of contacts at service tiers that require agent activity. Agents are allocated to contacts by a dynamic automate contact distributor and the appropriate media router is used to route the contact to an agent. The workflow engine also executes workflows for agents to control the allocation of agents to contacts.
