Title: Release mechanism for a vacuum hose
Inventor: MCQUARRIE KEITH
IPC: F16L35/00
Filed: 1992-12-29
Granted: 1996-11-19
Abstract: A release mechanism for use with vacuum cleaning appliances having a pipe and hose arrangement, where the pipe is slidably mounted inside the hose. The release mechanism comprises an inner sleeve, an outer sleeve and actuating buttons. The inner sleeve couples the pipe to the hose. By using the actuating buttons, the inner sleeve is operational in a closed position and an open position. In the closed position, the pipe can slide inside the hose, but it cannot be removed or detached from the hose. In the open position, the pipe can be removed or detached from the hose. The outer sleeve secures the release mechanism to the hose and houses the inner sleeve and actuating buttons.

Title: Method for conditioning flue gas
Inventor: HANKINS WILLIAM G
IPC: B01J12/00
Filed: 1993-01-15
Granted: 1996-11-26
Abstract: A method for conditioning flue gas to improve the removal of fly ash by an electrostatic precipitator employs a relatively high concentration (4-7%) of SO3 conditioning agent. The SO3 is formed by combusting sulfur and excess air in a sulfur burner to produce a mixture of air and SO2 and converting the SO2 to SO3 in a catalytic converter. The ratio of air to sulfur is maintained constant over a wide range of SO3 production rates, and the air is unheated during most production rates. The mixture of air and SO2 from the sulfur burner is cooled without increasing the volume of the gaseous mixture.

Title: Adaptive coding level control for video compression systems
Inventor: PAIK WOO H
IPC: H04N7/50
Filed: 1993-05-17
Granted: 2000-01-25
Abstract: An apparatus and method for adaptively compressing blocks of video image data provide a local ceding level (34) for use in compressing successive blocks of video image data. Each block is preliminarily compressed (30) using a global coding level. The preliminarily compressed data is processed (32) to provide a measure of the randomness of an image area represented by the block of video image data. A local coding level is generated (34) based on the randomness measure. The video image data is then compressed (36) using the local coding level to provide compressed data far transmission. One or more intermediate compression stages (16, 18) can be provided, each generating an intermediate coding level (ICL), to better refine the randomness measure for use in generating the local coding level.
Patent CA-2104539-C (CA)
Inventor: HAGENSON RANDY L
IPC: C08G75/02
Filed: 1993-08-20
Granted: 1997-12-30
Abstract: A method is provided for selectively extracting the lower molecular weight  fraction of a poly(arylene sulfide) polymer by contacting the polymer with a polar organic compound and a promoter compound to form a less dense polymer-lean liquid phase and a more dense polymer-rich liquid phase, separating the polymer-lean liquid phase from the polymer-rich liquid phase, and recovering the polymer from the polymer-rich phase.  Alternatively, either of the phases can be isolated and polar organic compound and optionally promoter can be added to form two new phases, followed by isolation of the new polymer-rich phase. This process can be repeated as often as desired or practicable in order to recover polymer having a desired molecular weight and/or molecular weight distribution.

Title: Dipole detection and localization processing
Inventor: BREED BEN R
IPC: G01B7/004
Filed: 1994-02-10
Granted: 1997-12-30
Abstract: Dipole detection and localization systems and methods employing improved processing techniques.  The first processing technique provides for higher spatial resolution by implementing maximum likelihood beamforming processing to detect and locate a dipole in a manner analogous to the processing of wave propagation phenomena. The high resolution technique is comprised of using data derived from an array of magnetic sensors that is arranged in the form of a vector of coefficients in lieu of a matrix.  This vector can be either the magnetic field components or the Andersonfunction expansion coefficients and is used to form a dyadic matrix, to which a multiple of an identity matrix is added to prevent singularity.  The second improvement uses more than three Anderson function expansions to achieve detection and localization of the dipole.  The use of more than three Anderson functions more effectively normalizes out the noise dependence by providing better noise representations, and provides fordetection and localization of multipoles. The third improvement provides for multiple-pass multiple-target processing of data measured by the array of sensors. First, the location of the largest dipole in the field-space of the array is determined, and its moment and orientation are determined. The field due to a dipole at that location and orientation is then removed from the measurement data and the process is repeated. The field isremoved by subtracting out its contribution at each of the sensors in the array, and then estimating the location of the next largest dipole. Simulations have shown that this process provides the ability to resolve multiple dipoles, when applied as many times as is needed.  Among other fields of use, the present invention has application in non-acoustic anti-submarine warfare applications.

Title: Combined product shipping and display box
Inventor: EDGERTON ERIC JR
IPC: B65D5/4805
Filed: 1994-10-11
Granted: 1997-12-16
Abstract: A combined shipping and display box is provided which is formed from a one-piece blank of box-board material configured such that, when erected, the box will include bottom, front and rear walls as well as an opposed pair of side walls.  The side walls are each formed from respective side panels having a central sub-panel and a pair of divider sub-panels extending in opposite directions from the central sub-panel.  These divider sub-panels are inwardly foldable onto their respective central sub-panel along predetermined fold lines so as to not only be positioned in adjacent contact with the central sub-panel, but also to establish protruding interior dividers for the shipping/display box.  When erected, therefore, the terminal edges of each respective pair of divider sub-panels will abut one another such that each of the interior dividers is paired with a similar interior divider associated with the opposite side wall.  In such a manner, therefore, the paired dividers will establish box positions adapted to hold a selected number of prepackaged product containers in a desired array.  The dividers, moreover, protect the prepackaged product containers held thereby against movement (and hence potential damage) during shipping.
