Title: Methods for producing polyol fatty acid polyesters using atmospheric or superatmospheric pressure
Inventor: KENNEALLY COREY JAMES
IPC: C07C67/02
Filed: 1997-07-16
Abstract: Methods for the solventless transesterification of a polyol comprise reacting polyol with fatty acid alkyl ester in the presence of a basic catalyst to produce polyol fatty acid polyester product and lower alkyl alcohol by-product, wherein a majority of the polyol is fully esterified. The reaction is conducted in a reactor at a temperature in the range of from about 60 ~C to about 180 ~C and at atmospheric or superatmospheric pressure. An inert gas is sparged through the reactor with sufficient mass transfer surface area contact between the inert gas and reactor liquid to transfer the lower alkyl alcohol by-product from a liquid mixture of reactant and product to the inert gas and promote full esterification of a majority of the polyol without the use of vacuum pressure.

Title: Multiple size reductions for image segmentation
Inventor: KRTOLICA RADOVAN
IPC: G06K9/20
Filed: 1999-04-01
Abstract: A sample image (144) is segmented by are image segmentation system (120) including a size reduction unit (134), which reduces the size of the image (144), and, at the same time, fills small gaps between foreground pixels. Thereafter, a connected component analyzer (136) identifies connected components and their associated minimum bounding rectangles in the reduced image (145). Next, a target object filter (138) searches the connected components for target objects, making use of a target object library (146) to identify target objects characterized by such parameters as size, shape, and texture. Finally an inverse mapper (140) locates the bounding rectangles of the target objects in the original sample image (144), and extracts the associated portions of the image (144) for analysis in a conventional image classifier (142).

IPC: A47B88/493
Filed: 1999-04-28
Abstract: A drawer pull-out guide that consists of a guide rail 11 that can be fastened to a piece of furniture 12, a slide rail 14 guided by means of rolling elements and attachable to the drawer 16, and a profiled rail 16 having tracks for the rolling elements at one end area or at both end areas is to be made in a simple to construct manner in such a way that the lateral stability of the drawer pull-out guide is clearly improved without increasing the structural parts. In the drawer pull-out guide 10 of the invention, the area of the profiled rail 13 adjoining the tracks is staggered, at least by area, vis-à-vis the vertical in such a way that this area is situated in direction or almost in direction of the resulting lateral forces acting on the drawer pull-out guide 10. For this reason, the area of the profiled rail adjoining the tracks is diagonal vis-à-vis the vertical, however, it is essentially straight or also curved, nevertheless, this area can also be bent repeatedly in the same or opposite directions or have a zigzag shape. The drawer pull-out guide of the invention is particularly suitable for house furniture.

Title: Method and apparatus for determining the centre photodetector in a digital scintillation camera
Inventor: SCHRECK ZOLTAN
IPC: G01T1/208
Filed: 1999-06-04
Abstract: A  method and apparatus for determining the centre photodetector in a planar array of photodetectors of a gamma scintillation camera is provided.  The analog signals generated by a plurality of photomultiplier tubes (PMT) following a scintillation event, are digitized, integrated, and stored in a first memory. A first comparison means is used to divide the set of PMT logical signals into groups.      Each group comprises an arbitrary number of PMTs. The PMT logical signals within a group are combined into pairs and compared to select the highest intensity value for each individual group. Subsets of local PMT highest intensity values are created. A second comparison means is used to receive the subsets of local PMT highest values, combine them into pairs, compare the paired signals, and record the selected signals in a second memory, until a PMT with the maximum intensity value or a centre PMT is obtained. The data stored during processing are then arranged in a versatile look up table to facilitate the assembly of relevant information characterizing the distribution of scintillations around the centre photodetector.

Abstract: A structure, particularly a structure subject to collision or vandalism such as a bridge, is monitored by instruments such as an acoustic sensing system, strain guages, accelerometers and rotation sensors. A video, infrared or like record is made of the structure and kept for a predetermined period. Criteria are established to determine instrument readings which indicate a condition of possible damage, called a triggering event. When a triggering event is recorded, the video record of the time immediately before the event is saved to help identify what happened and the perpetrator, if any. In preferred embodiments, verification is made of whether damage occurred and the extent of damage is assessed.

Title: Hip protection device for the elderly
Inventor: WIENER STANLEY L
IPC: A41D27/26
Filed: 1997-04-07
Abstract: A hip protection device for the elderly which provides protection to the trochanter region of the wearer to prevent fracture thereto upon falling from a standing position. An undergarment (22) is provided with at least one pocket (24) enclosing a pad (26), or other alternative arrangements for securing the pads (26) to the hip regions of the garment. Each protective pad (26) defines an open-ended channel having an elongated major axis along which it is substantially linear and a minor axis which has a generally parabolic curvature. The undergarment (22) and the pad (26) are configured such that the pads (26) wrap around and fit snugly against the trochanteric area of the wearer's hip. Each pad (26) has a relatively rigid thin shell (32) on its convex side and a relatively thin layer of resilient impact absorbing material (34) on its concave side. Upon the wearer falling from a standing position onto their hip area, the impact force is distributed generally uniformly across the surface area of the rigid shield (32) and then to the resilient impact absorbing material (34), which has sufficient resilience and thickness that is greater than ninety percent of the absorbed impact force. In one embodiment for incontinent persons, a diaper is detachably engageable with the undergarment.

Title: A method for extracting quantitative information relating to an influence on a cellular response
Inventor: SCUDDER KURT
IPC: G01N33/50
Filed: 1998-04-07
Abstract: Cells are generically modified to expresss a luminophore, e.g., a modified (F64L, S65T, Y66H) Green Fluorescent Protein (GFP, EGFP) coupled to a component of an intracellular signalling pathway such as a transcription factor, a cGMP- or cAMP-dependent protein kinase, a cyclin-, calmodulin- or phospholipid-dependent or mitogen-activated serine/threonin protein kinase, a tyrosine protein kinase, or a protein phosphatase (e.g. PKA, PKC, Erk, Smad, VASP, actin, p38, Jnk1, PKG, IkappaB, CDK2, Grk5, Zap70, p85, protein-tyrosine phosphatase 1C, Stat5, NEAT, NFkappaB, RhoA, PKB). An influence modulates the intracellular signalling pathway in such a way that the luminophore is being redistributed or translocated with the component in living cells in a manner experimentally determined to be correlated to the degree of the influence. Measurement of redistribution is performed by recording of light intensity, fluorescence lifetime, polarization, wavelength shift, resonance energy transfer, or other properties by an apparatus consisting of e.g. a fluorescence microscope and a CCD camera. Data stood as digital images are processed to numbers representing the degree of redistribution. The method can be used as a screening program for identifying a compound that modulates a component and is capable of treating a disease related to the function of the component.
