Abstract: An apparatus for shaping a slab of compressible or cellular polymer material (80), such as polyurethane foam, by cutting portions of the material from one surface. A moving patterned platform (32), preferably an endless belt or a series of interconnected panels, is interposed between a compression roller (56) and a support surface (46) and defines at least one recess (36). When the slab is compressed between the compression roller and the platform, which is supported by the support surface, a portion of the material fills the recess or recesses in the moving platform. At least a portion of the compressed material within the recesses is then cut from the surface of the slab by a blade (76) just as the slab emerges from between the compression roller and the platform leaving a profile-cut surface with cut-out portions corresponding in pattern and shape to the recesses provided on the moving patterned platform.

Title: Table leg wire management apparatus
Inventor: SCHWINGHAMMER SCOTT
IPC: A47B21/06
Filed: 1999-04-29
Granted: 2008-06-17
Abstract: A furniture leg wire management apparatus is configured for use with a furniture leg formed by opposite leg posts separated by a gap. The apparatus includes a legway defined by an elongated tubular body. The body includes a forward portion and opposite clamping arms that are resiliently deflectable toward each other. The clamping arms are deflected when the legway is pushed into the gap between the leg posts and provide an outwardly directed force to clamp the legway in this operative position. The tubular body further includes a central rib terminated in a rear flange. The central rib divides the legway into two wire/cable channels, while the rear flange cooperates with the clamping arms to define opposite elongated slots. The slots communicate with the two cable channels to provide an avenue to feed the wires/cables into a corresponding channel. The wire management apparatus further includes a decorative cover plate that is removably mounted on the legway to improve its aesthetics.

Abstract: A deformable, artificial intraocular corrective lens for implantation into the human eye to correct normal vision problems. The lens may be positioned posteriorly from the iris, resting against the anterior surface of the posterior capsule's natural lens. Alternatively, the lens may be positioned in the anterior chamber of the eye. The implanted lens works in conjunction with the cornea and natural lens to provide proper vision, as a substitute for regular contact lens, spectacles, and radial keratotomy. The lens may be designed from a rigid or semi-rigid material. Due to the thinness of the structure, the lens may be rolled and inserted into the eye, minimizing both the length cf the corneal incision and the stretching of the cornea.

Abstract: Power quality detection, monitoring, reporting, recording and communication in a revenue accuracy electrical power meter is disclosed. Transient events are detected by monitoring the wave shape of the electrical power and comparing deviations to a known threshold. Sags and Swells are detected by computing root mean square value over a rolling window and comparing the computed value with a known threshold. Harmonic frequencies and symmetrical components are quantified by a known algorithm and compared with a known threshold. Incoming waveforms are stored to memory. All recorded and computed data is moved to non-volatile storage via direct memory access transfer in the event that a power quality event jeopardizes the operating power of the meter. Further, the meter provides a power supply utilizing high and low capacitive storage banks to supply sufficient energy to survive short duration power quality events which jeopardize the meter's operating power.

Abstract: The invention concerns a device for the gripping and retention of part of a split carcass by the spinal column (17), and the conveyance of that part essentially in the lengthwise direction of the spinal column, while retaining it by the spinal column during processing of the carcass part by means of cutting tools. The device comprises a mainly rectilinear conveyor (10) with retention elements (11) connected as links in an endless chain, with each element having a first section (21) with a contact surface (22) for a first side of the spinal column and a second section (25) with a pressure surface (26) for a second side of the spinal column. The two sections of each element are designed to allow the contact surface (22) and the pressure surface (26) to be relatively moved towards and away from each other in a direction across the conveyor's direction of conveyance. The spinal column can be gradually gripped and clamped between the surfaces (22, 26) when the contact surface (22) and pressure surface (26) are successively, element by element, moved towards each other. The device provides a firm grip between the spinal column and the machine parts of an apparatus for processing of e.g. fore-ends or middles.

Title: Methods and reagents for decreasing allergic reactions
Inventor: COCKRELL GAEL
IPC: C12N5/00
Filed: 1999-01-29
Granted: 2009-06-16
Abstract: It has been determined that allergens, which are characterized by both humoral (IgE) and cellular (T cell) binding sites, can be modified to be less allergenic by modifying the IgE binding sites. The IgE  binding sites can be converted to non-IgE binding sites by masking the site with a compound that prevents IgE binding or by altering as little as a single amino acid within the protein, most typically a hydrophobic residue towards the center of the IgE-binding epitope, to eliminate IgE binding. The method allows the protein to be altered as minimally as possible, other than within the IgE-binding sites, while retaining the ability of the protein to activate T cells, and, in some embodiments by not significantly altering or decreasing IgG binding capacity. The examples use peanut allergens to demonstrate alteration of IgE binding sites. The critical amino acids within each of the IgE binding epitopes of the peanut protein that are important to immunoglobulin binding have been determined. Substitution of even a single amino acid within each of the epitopes led to loss of IgE  binding. Although the epitopes shared no common amino acid sequence motif, the hydrophobic residues located in the center of the epitope appeared to be most critical to IgE binding.

Title: Pressure swing adsorption gas separation method, using adsorbents with high intrinsic diffusivity and low pressure ratios
Inventor: SMOLAREK JAMES
IPC: C01B13/02
Filed: 1999-02-26
Granted: 2007-04-24
Abstract: A gas separation process incorporating the invention combines use of an adsorbent having high intrinsic diffusivity with a low pressure ratio PSA cycle. Further enhancements to the process are derived from the use of fast cycles, shallow beds and small particles - especially in a radial bed configuration. The combination of low pressure ratio, high rate adsorbents and fast cycles has been found to result in an unexpected simultaneous reduction in bed size factor (BSF) and power consumption. These benefits have been achieved while minimizing a decline. in product recovery through use of the high rate adsorbent. The net result is a significant reduction in product cost.
