Title: Battery circuit with non-volitable memory and thermistor on a single line
Inventor: SIMPSON RUSSELL L
IPC: H02J7/00
Filed: 2005-02-07
Abstract: A system (200) includes a battery charger (278) and a battery (202). The battery (202) includes a thermistor (230), a voltage identifying element (240), a switch (244), a memory device (232), and a battery data contact (228), connected to a data port of the memory device (232) and the voltage identifying element (240). The voltage identifying element (240) determines a voltage that controls the switch (244). When the switch (244) is enabled, the thermistor (230), connected to a battery clock contact (224), is active and a microprocessor (102) on the battery charger (278) reads the value of the thermistor (230) via an analog-to-digital converter. When the switch (244) is disabled, the thermistor (230) is switched out and the battery clock contact (224) is used to clock the memory device (232). The battery charger (278) has a data contact (226) for receiving the battery data contact (228) and a clock contact (222) for receiving the battery clock contact (224). The battery charger (278) further includes at least two switches (204,206), and the microprocessor (102) is programmed to selectively operate the switches (204,206).

IPC: E06B1/00
Filed: 2006-08-29
Abstract: An bi-directional mounting bracket assembly is utilized in conjunction with exterior siding that covers sheathing of an exterior wall. A base member of the assembly has a mounting flange secured to the sheathing and a wall arrangement that projects outward with respect to the sheathing and from the mounting flange.  Preferably, the wall arrangement supports a raised central panel used for mounting of fixtures. The wall arrangement preferably has four walls extending laterally between the mounting flange and the central panel. Spaced radially outward from the two adjacent walls are respective first and second drip ledges, and spaced radially outward from the other two adjacent walls are respective first and second baffle sets. When the assembly is mounted to the sheathing, a selective one of the two drip ledges is disposed substantially horizontally and beneath the wall arrangement for shedding of water. The baffle set adjacent to the horizontal drip ledge cascades water downward and generally toward the respective wall to channel water upon the horizontal drip ledge.

Title: Natural gas liquefaction
Inventor: CUELLAR KYLE T
IPC: F25J3/02
Filed: 2004-04-26
Abstract: A process for liquefying natural gas in conjunction with producing a liquid stream containing predominantly hydrocarbons heavier than methane is disclosed. In the process, the natural gas stream to be liquefied is partially cooled, expanded to an intermediate pressure, and supplied to a distillation column. The bottom product from this distillation column preferentially contains the majority of any hydrocarbons heavier than methane that would otherwise reduce the purity of the liquefied natural gas. The residual gas stream from the distillation column is compressed to a higher intermediate pressure, cooled under pressure to condense it, and then expanded to low pressure to form the liquefied natural gas stream.

Title: Dendritic polymers with enhanced amplification and interior functionality
Inventor: SWANSON DOUGLAS R
IPC: C08J3/00
Filed: 2005-04-20
Abstract: Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymer are made by use of fast, reactive ring opening chemistry (or other fast reactions) combined with the use of branch cell reagants in a controlled way to rapidly and precisely build dendrimer structures, generation by generation, with precise structures with cleaner chemistry, typically single products, lower excesses of reagants, lower levels of dilution, higher capacity method, more easily scale to commercial dimensions, new ranges of materials, and lower cost. The dendrimer composition prepared have novel internal functionality, greater stability, e.g., thermal stability and less or no reverse Michaels reaction, and which reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of poly-functional branch cell reagents with polyfunctional surfaces do not create gelled materials. Such dendritic polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, proton scavengers, calibration standards for electron microscopy, making size selective membranes, and agents for modifying viscosity in aqueous formulations such as paint. When these dendritic polymers have a carried material associated with their surface and/or interior, then these dendritic have additional properties due to the unique characteristics of the dendritic polymer.

Inventor: JASSO ABELARDO
IPC: B23B51/04
Filed: 2005-04-06
Abstract: The hole saw slug removal device (10) is a device constructed to fit within a hole saw (12) that provides for automatic ejection of waste slugs from within the hole saw. The hole saw slug removal device (10) generally consists of two discs (22, 24) affixed on either end of a compression spring (20). The device (10) is then inserted into the hole saw, and one disc (24) retains the compression spring within the hole saw by locking onto the drill bit (30) or against the inner surface of the hole saw (12). Upon operation of the hole saw, the spring compresses and the other disc (22) is pushed down by the force of the sawing. After the sawing is completed, the spring decompresses, and the disc (22) is pushed forward, automatically ejecting the waste slug that has become trapped. The slug removal device may lack one disc and instead be permanently affixed to a hole saw.

Inventor: WADSWORTH HARRY
IPC: A61K51/08
Filed: 2005-07-19
Abstract: The present invention provides tetra-amine chelator conjugates with biological targeting moieties, linked via a linker group and technetium complexes thereof as radiopharmaceuticals. The linker group is such that the chelator is mono-functionalised at the bridgehead position and provides both flexibility and a lack or aryl groups, to minimise lipophilicity and steric bulk. Protected versions of the chelators are provided, which permit conjugation with a wide range of targeting molecules without interfering reactions with the amine nitrogens of the tetra-amine chelator. Syntheses of the functionalised chelators are described, together with bifunctional chelate precursors.  Radiopharmaceutical compositions comprising the technetium metal complexes of the invention are described, together with non-radioactive kits for the preparation of such radiopharmaceuticals.
