Title: Enhancing filtration yields in tangential flow filtration
Inventor: SCHICK KARL G
IPC: F04B49/06
Filed: 2001-06-22
Granted: 2010-04-27
Abstract: A system is provided for proceeding with filtration of liquids in a manner having enhanced control characteristics. Yields are enhanced. The system and method can be used to maintain a substantially constant trans-membrane pressure. When desired, that constant trans-membrane pressure is especially well-suited to yield enhancement for the particular liquid being filtered, concentrated or collected, while minimizing a risk of damage to or loss of valuable components. Additionally, a constant feed rate or pump output can be maintained. Approaches also are described for determining optimal filtration conditions, including trans-membrane pressure and feed rate. Also described is a system and method for determining pressures in a pulsating system with enhanced accuracy by using a peak pressure mode.

Patent CA-2418766-C (CA)
Inventor: HUDAK JOSEPH C
IPC: F21V17/10
Filed: 2003-02-12
Granted: 2007-12-11
Abstract: A bandless seam between reflector and refractor sections of a luminaire globe formed of light-transmissive material and configured to improve optical performance as well as facilitate effective mounting of the reflector and refractor sections together, the invention finds particular utility with suspended luminaires ordinarily requiring a metal band or the like to join said sections into a luminaire globe. Opposing peripheral edge surfaces of the reflector and refractor sections are shaped according to the invention not only to cause even flow of adhesive between said surfaces to adhere said sections to each other but also to reduce brightness at the resulting seam between the sections, thereby improving luminaire appearance and reducing seam brightness and optical glint.

Granted: 2010-02-23
Abstract: A dual volume air spring (5) for a truck suspension, which has an air bag chamber providing a variable volume (6) and a fixed volume chamber (7). The chambers are interconnected by a closable orifice (12). The air bag is provided with a post-like orifice closer (20) which is pushed into the orifice when the air bag (9) is sufficiently compressed ad withdrawn from the orifice when the air bag is not compressed. In normal operation the orifice is open and combined volumes of the chambers are available resulting in a low spring rate. The orifice closer (20) has an orifice closing portion (22) which is relatively pliant and a rigid or semi-rigid portion (21) which acts as a bump-stop when the pliant portion is substantially completely compressed. When the orifice is completely closed the spring has a high spring rate.

Abstract: Apparatus for twisting off crown bottle caps. A main body in side view is flattened and has a thickness, with a circular opening through the thickness, the opening large enough to accommodate the diameter of a crown bottle cap. The circumferential edge of the opening is formed into a plurality of pairs of facets, each pair of facets forming a notch. The walls of the facets are not parallel to one another but instead taper toward one another and farm generally pyramidal shapes which intersect, or come to a point, within the main body thickness. An inverted triangular shape is formed between each pair of facets. A bottle cap is inserted into the opening, where the notches formed by the facets closely engage the bottle cap jags. The contour of the main body then permits the user to readily twist off the bottle cap.

Filed: 2003-03-20
Granted: 2010-11-16
Abstract: A method and system for authentication of a mobile device that includes a mobile device and a network element in a communications network. The network element may be a call state control function. If the network element detects an incorrect event related to a mobile device (S3), the network element shortens a registration validity time for the mobile device (S4) and sends the mobile device a notification to re-authenticate (S5). The incorrect event can be, for example, an incorrect authentication response, an incorrect action by the mobile device, a session over a time maximum, traffic generated being over a maximum, or credit run out. The mobile device is de-registered if the mobile device falls to re-authenticate within the shortened registration validity time (S8), and re-registered if the mobile device re-authenticates within the shortened registration validity time (S10). The registration validity time for the mobile device is extended after re-registration.

Title: Roaming method between wireless local area network and cellular network
Inventor: SHIN YONG-SIK
IPC: H04W76/02

Granted: 2012-07-10
Abstract: The present invention relates to a roaming method between a WLAN and a cellular network which can interwork the WLAN and the cellular network on the basis of a mobile IP system for smooth roaming. In data communication in the WLAN and/or the cellular network using the mobile IP system, the roaming method between the WLAN and the cellular network includes a step wherein a packet data serving node of the cellular network which recognizes allocation of an IP address to a specific mobile terminal notifies information on a current access state of the mobile terminal to an access point managing means of the WLAN located in a current service area of the mobile terminal, a step wherein the access point managing means which the mobile terminal newly accesses requests address renewal to replace an address of the packet data serving node by its address, allocates an IP address to the mobile terminal according to the renewal result, and notifies it to the packet data serving node, and a step wherein the packet data serving node which receives the notification message from the access point managing means transmits data obtained during the roaming due to the movement to the access point managing node, whereby the roaming is performed from the cellular network to the WLAN. In the same manner, the roaming can be performed from the WLAN to the cellular network.

Abstract: A carpet web and a method of forming a carpet web having a striped pattern a nd color scheme that permits carpet tiles cut from the web to be installed without regard to relative tile positions and without visibly disrupting the pattern, but rather maintaining the appearance of a broadloom web. The web pattern includes parallel stripes having varying widths and longitudinal discontinuities. The stripes are formed with at least two colors or two shad es of a color. The tiles are positionally ambiguous in that they need not be located on the floor in the same position they occupied in the web for the flooring installation to exhibit the desired uniform appearance. Instead, th e tiles may be shuffled and laid in any side-by-side or top-to-bottom orientation (provided that uniform rotational orientation is maintained amon g the tiles) with respect to adjacent tiles without looking out of place to th e ordinary viewer and without emphasizing the modularity of the flooring.</SDO AB>
