Title: Battery charging method and apparatus
Inventor: BOHNE WILLIAM C
IPC: H02J7/00
Filed: 1994-12-12
Abstract: A method and apparatus for battery charging in which over and under charge is prevented by taking into account the fact that the full charge voltage of a battery may vary with the age or condition of the battery. A battery charger (20) charges a battery (11), preferably in a battery pack (10), by providing an initial battery charging current (I1) and terminating the initial charging current at a time t2 in response to a measured battery condition (for example, battery temperature rate of change; Delta T/Delta t) exceeding a limit. A battery parameter, preferably battery voltage, is measured at the time t2 and stored as a limit (Vpeak). After t2, battery charging current is provided in accordance with a predetermined criteria and battery response to comparing a measured battery parameter, preferably battery voltage, after t2 to a threshold (vpeak; or Vpeak - Delta V) based on the stored limit (Vpeak). Preferably, rapid battery charging is implemented in response to a comparison of a measured battery parameter, preferably battery voltage, after the time t2 with respect to a threshold (Vpeak - Delta V) determined in accordance with the stored limit (Vpeak).

Abstract: The invention relates to a process for the production of series-produced valves which are used in heating, ventilating and air-conditioning systems and which comprise a cast-iron valve body, at least one stainless steel valve seat disposed in a flow restrictor opening in the valve body and an actuating rod having at least one flow restrictor, the actuating rod being taken out of the valve through a cover which closes an opening for the cover in the valve body, such opening being in alignment with the valve seat.  The valve seat is welded into a casting serving as blank for the valve body without previous chip removal treatment of the casting surface, in one chucking.  The blank is then finish-treated.  Preferably, the valve seat is produced by build-up welding followed by chip removal shaping of the weld bead. - Fig. 1.

Title: Method for reducing the viscosity of pathological mucoid airway contents in the respiratory tract
Inventor: STOSSEL THOMAS P
IPC: C07K14/47
Filed: 1994-04-04
Abstract: The invention is generally directed to methods of promoting normal respiratory tract airflow in patients with restricted airflow and ciliary clearance caused by the presence of pathological airway contents, and particularly mucoid contents. Actin-binding proteins are administered into the respiratory tract of a patient with a pathological respiratory condition involving the presence of such contents. The actin-binding protein binds to actin polymers in the contents and decreases the viscosity. The actin-binding proteins also prevent actin from binding to exogenous or endogenous DNase 1, thus increasing the degradation of DNA polymers in the contents.

Title: Method and apparatus for background determination and subtraction for a monocular vision system
Inventor: BRADY MARK J
IPC: G08G1/04
Filed: 1994-11-23
Abstract: A method and apparatus for producing a background image from a plurality of images of a scene and for subtracting a background image from an input image are described. A background image is produced by dividing an image (40) into subim-ages (42), acquiring reference subimages (48) for each subimage location and comparing subsequent subimages with the reference subimage to deter-mine if my objects have passed between the ref-erence subimage and the video camera (22) that acquired images. When objects have passed be-tween the reference subimage and the video cam-era (22), the reference subimage is designated as background and stored in a background image (50). Background portions of an input image can be re-moved or then intensity diminished with a back-ground image. Foreground weights can be deter-mined by comparing the difference between a back-ground image and an input image. To the extent that corresponding pixels are the same, the pixel is given a low foreground weight, indicating that the pixel is a background weight. The background subtraction method can further employ a weighting curve (70) to take nnto account noise considertions. The fore-ground weights are then applied to an input image to diminish or remove pixels in the background
Patent CA-2178757-A1 (CA)
Title: Visual power on indicator
Inventor: RODGERS BARRY
IPC: H02H1/06
Filed: 1995-10-13
Abstract: The present invention provides a low burden visual POWER ON indicator for a self-powered electrical circuit protection device.  The visual indicator includes a current transformer for producing an induced current in direct proportion to the current supplied to an electrical device protected by the protection device.  The induced current is summed and rectified.  An  energy accumulator stores a predetermined voltage required to operate the protection device. The stored voltage is controlled by an accumulation switch wich in turn is controlled by a hysteresis control circuit.  The hysteresis control circuit includes an operational amplifier which is biased by a stable reference voltage. When the voltage on the eneregy accumulator is equal to the stable reference voltage the operational amplifier produces a HIGH output signal. When the voltage on the energy accumulator is less than the stable reference voltage the operational amplifier produces a LOW output signal.  A HIGH output signal causes the power accumulation switch to close thereby diverting current away from the energy accumulator. A LOW output signal opens the power accumulation switch causing current to flow to the energy accumulator thereby charging it. An LED is electrically connected to the operational amplifier such that it is illuminated only when the operational amplifier produces a HIGH output signal and thereby provides a visual indication of the POWER on state of the protection device.

Abstract: Onium salts of taxo-diterpenoid-Cn, 2-0-aza-arenes are employed as water soluble prodrugs. For example, taxol-2'-methylpyridinium tosylate (MPT) is characterized by an elevated aqueous solubility, rapid activation by serum protein, good stability in most other aqueous solutions, formation of a protein:taxol intermediate and good retension within the circulatory system.  The toxicity of the activated form is comparable or greater than underivatized taxol. Furthermore, taxol-2'-MPT can be synthesized by a simple one step reaction between taxol and 2-fluoro-1-MPT. The invention is applicable to taxol and taxol mimetics having hydroxyls that are reactive with onium salts of 2-halogenated-aza-arenes. For example, taxol, C-2 substituted analogs of taxol, and Taxotere each have reactive hydroxyls at the 2' and 7 positions.  The invention is also applicable to a wide array of 2-halogenated-aza-arenes.
