Abstract: An electric machine such as a direct current motor or generator in which a stator is formed using a set of electrically conductive blade structures disposed about an inner axis of a stator core. Electrical interconnections between the conductive blades are provided by a set of disks connected to the ends of the blades. The disks are formed preferably from an insulating substrate material having electrically conductive pads formed thereon to provide circuit interconnections between the blades. A desired path for current flow is provided by arranging the blades and conductive pads on the disks appropriately in the desired number of turns and phases. The conductive blades and conductive portions of the interconnect disks are formed, in a preferred embodiment, from a material such as a copper and molybdenum laminate.

Title: Shock-absorbing tool handle
Inventor: SHAUD RONALD J
IPC: B25G1/04
Filed: 1999-04-08
Granted: 2006-07-25
Abstract: A shock-absorbing telescoping tool handle (2) is disclosed having a larger diameter proximal portion (4) and a smaller diameter distal portion (6). An internal spring (14) in the handle portions is compressed when the handle portions telescope towards each other upon shock being applied to the tool handle. Guide mechanisms (26, 28) in the handle portions limit the extend of sliding motion between the handle portions and prevent relative motion of the handle portions. One or more wipers (40) in the handle portion wipes away any snow, water or debris on the distal portion which could potentially enter the spring area. The spring may be located within the proximal portion or the distal portion of the tool handle.

Abstract: An electronic article surveillance system responsive to the distance to a target within an interrogation zone is provided. The interrogation zone is defined by an electromagnetic field generated with a known level and transmitted by at least one antenna. A target within the interrogation zone can be any object, such as a person or shopping cart, within the interrogation zone. The target may include an EAS marker securable to an article for passage through the interrogation zone. The EAS marker is detectable at a frequency when in the electromagnetic field, and is detected by EAS detection equipment, as known in the art. The target within the interrogation zone is detected, and the distance from the antenna to the target is measured. The level of the electromagnetic field is controlled according to the distance to the target within the interrogation zone. The output level is adjusted according to the distance to the target. The EAS system can include multiple antennas each producing an electromagnetic field that in combination define the interrogation zone. A ranging transducer is mounted near each antenna, or at opposing ends of the interrogation zone to measure the distance to a target within the interrogation zone. The output level of each electromagnetic field transmitted by each antenna can be individually controlled according to the distance from that antenna to the target. Multiple targets can be detected, and the power level of each electromagnetic field is adjusted accordingly. T he electromagnetic field can be switched off and on by detection of the target in the interrogation zone. The direction of motion o f the target can also be detected and used as a factor in alarm activation decisions.

Title: Pyrophosphorolysis activated polymerization (pap): application to allele-specific amplification and nucleic acid sequence determination
Inventor: LIU QIANG
IPC: G01N33/58
Filed: 2001-02-22
Granted: 2011-08-02
Abstract: A novel method of pyrophosphorolysis activated polymerization (PAP) has been developed. In PAP, pyrophosphorolysis and polymerization by DNA polymerase are coupled serially for each amplification by using an activatable oligonucleotide P* that has a non-extendable 3'-deoxynucleotide at its 3' terminus. PAP can be applied for exponential amplification or for linear amplification. PAP can be applied to amplification of a rare allele in admixture with one or more wild type alleles by using an activatable oligonucleotide P* that is an exact match at its 3' end for the rare allele but has a mismatch at or near its 3' terminus for the wild type allele. PAP is inhibited by a mismatch in the 3' specific subsequence as far as 16 nucleotides away from the 3' terminus. PAP can greatly increase the specificity of detection of an extremely rare mutant allele in the presence of the wild type allele. Specificity results from both pyrophosphorolysis and polymerization since significant nonspecific amplification requires the combination of mismatch pyrophosphorolysis and misincorporation by the DNA  polymerase, an extremely rare event. Using genetically engineered DNA  polymerases greatly improves the efficiency of PAP.

Title: Improved heat exchanger with floating head
Inventor: CALANOG MARCIANO M
IPC: F28F9/18
Filed: 2003-04-04
Granted: 2010-12-21
Abstract: A heat exchanger in which dead zones and areas of stagnation are significantly minimized or eliminated. The heat exchanger includes at least one floating tubesheet which is movable in a longitudinal direction in response to tube expansion and contraction relative to the heat exchanger shell. The shell is joined to the ends by conical members which preferably join onto the shell at a distance along its length to provide shell extensions which promote better flow patterns in the regions of the tube ends. Tube erosion may be addressed by providing a sacrificial portion of tube length extending beyond the tube sheets so as to make repair and replacement of the eroded portion of tubes significantly cheaper, easier and with minimal process interruption. Because axial or longitudinal flow is employed with respect to the shell-side fluid, tube vibration problems are generally eliminated and fouling is minimized through the use of high fluid velocities. Multiple heat exchangers may be combined in a modular fashion by placing individual exchangers either in series, in parallel or both in order to satisfy various process requirements.
