Title: Absolute light intensity measurements in laser induced incandescence
Inventor: GULDER OMER L
IPC: G01N15/00
Filed: 1999-05-18
Granted: 2005-05-10
Abstract: The invention relates to a method and an apparatus for the determination of particle volume fractions with laser induced incandescence (LII) using absolute light intensity measurements. This requires a knowledge of the particle temperature either from a numerical model of particulate heating or experimental observation of the particulate temperature. Further, by using a known particle temperature a particle volume fraction is calculated. This avoids the need for a calibration in a source of particulates with a known particle volume fraction or particle concentration. The sensitivity of the detection system is determined by calibrating an extended source of known radiance and then this sensitivity is used to interpret measured LII signals. This results in a calibration independent method and apparatus for measuring particle volume fraction or particle concentrations. A modeling process involves a solution of the differential equations describing the heat/energy transfer of the particle and surrounding gas, including parameters to describe vaporization, heat transfer to the medium, particle heating etc. The solution gives temperature and diameter values for the particles over time. These values are then converted to radiation values using Planck's equation.

Patent CA-2274238-C (CA)

IPC: F16K3/18
Filed: 1999-06-10
Granted: 2004-12-14
Abstract: A gate assembly for a double disk gate valve having two closure disks with a resilient material between. The resilient material and closure disks are enveloped in an outer harder coating. Closing the gate valve brings the disks into initial sealing contact with the bottom of the valve seat. Applying pressure to the gate valve after contact is made between the gate assembly and the valve seat causes the resilient central member to exert pressure against the closure disks, thus pressing the outer coating of the gate assembly against the sidewalls of the valve seat. This action creates a better sealing engagement with the seat surface to exclude flow. Wear on the gate assembly is significantly reduced since the gate assembly does not make contact with the sidewalls of the seat while being moved between an open position and a closed position.

Title: Heat exchange element for a film heat exchanger and a method for manufacturing the same
Inventor: RAMM-SCHMIDT LEIF
IPC: B29C51/10
Filed: 1998-01-19
Granted: 2006-10-17
Abstract: The invention relates to a heat exchange element (1) for a film heat exchanger intended for distillation or for the evaporation of solutions or suspensions, and to a method for manufacturing the same. The substantially bag-like element is formed by bonding from oppositely positioned plastic heat exchange films (2), evaporation of liquid taking place on the exterior surfaces of the films and condensing of the obtained vapor taking place on the interior surfaces. In the bonding the interior (4) of the element is divided into ducts to direct the travel of the vapor, and according to the invention the films are at the same time stretched in the intervals between the bonding points (3) in order to provide leeway for bulging during the pressurization of the interior of the element. The element (1) may be made up of two heat exchange films (2) stretched by means of heat and a pressure differential between the different sides of the film, the films being bonded directly to each other, or there being bonded, between the heat exchange films to be stretched, one or more straight support films to improve the loadbearing capacity of the element.

IPC: B25C1/04

Abstract: The nailing tool has a hollow main body including a valve slidable therein. The main body includes a compressed air reservoir, the compressed air keeping the valve closed in a resting position. An anvil is provided at the upper end of the tool, with an empty annular chamber at atmospheric pressure being located under the anvil and over a ring integrally attached to the valve. Thus, if a hammer blow is dealt on the anvil, the latter loosely slides inside the main body, without reaching the ring, with the valve remaining closed and no fastener being expelled from the tool. Upon a trigger being activated on the tool handle, compressed air fills the annular chamber between the anvil and the ring. In this condition, upon a hammer blow being dealt on the anvil, the impact of the blow is transmitted by the compressed air to the underlying ring, consequently opening the valve. The opened valve allows compressed air to flow into an underlying piston drive chamber, where a piston is driven by the sudden compressed air inflow to drive a fastener out of the tool. Air exhaust channels allow the piston and the valve to return in their initial resting positions after a nail has been expelled from the tool.

Abstract: A method for controlling channel access in a mobile communication system. A  base station generates a broadcast channel frame, which includes status information indicating whether channel codes which are changing in real time are occupied or not. The base station transmits the broadcast channel frame at predetermined intervals. Then, a mobile station selects an available channel code based on information from the received broadcast channel frame, generates a channel assignment request message, and transmits the channel assignment request message on a random access channel. Upon reception of the channel assignment request message on the random access channel, the base station assigns a channel, sets a transmission rate, and transmits the information on a forward access channel.

Title: Master guide table for a digital broadcast protocol and method of broadcasting and receiving broadcast signals using the table
Inventor: KIM JIN PIL
IPC: H04N5/00
Filed: 2000-10-18
Granted: 2007-09-25
Abstract: A master guide table for a digital broadcast protocol, and a method of broadcasting and updating an electronic program guide using the table, uses identification information included in a bit stream syntax of the master guide table to classify whether contents of an event information table are merely shifted in time, or are actually changed. The master guide table is transmitted in accordance with a program and system information protocol (PSIP) for an advanced television system committee (ATSC) defined standard digital television broadcast protocol. A digital television receiver of a receiving party, or a digital cable broadcast receiver, can determine whether the contents of the event information table EIT are merely shifted in time or actually changed by parsing the identification information in the master guide table MGT. If the parsed contents of the identification information indicate that the event information table contents are merely shifted in time without any change, then a database maintaining previous event information table is not updated. Accordingly, time wasted in unnecessarily updating the database can be decreased.
