Title: Fluid flow monitor
Inventor: MUDDIMAN SCOTT
IPC: G01F1/56
Filed: 1997-09-15
Abstract: A fluid flow monitor has coaxial conductive annular supports separated by an insulating gasket and connected by a conductive member. One support has a lesserexternal diameter and a smaller internal diameter than the other to reduce the chance of accidental short circuiting. Wires are attached to each support, a third wire supplies a floating ground to ensure monitor tripping is not caused by a ground fault. Tabs on the inner perimeter of the supports may mount the conductive member.

Title: Amine-initiated polyether polyols and a process for their production
Inventor: DOERGE HERMAN P
IPC: C08G18/50
Filed: 1997-10-10
Abstract: Clear, amine-initiated polyether polyols are made by epoxidizing an amine in the presence of an alkali metal hydroxide catalyst. After the desired degree of epoxidation has been achieved, a hydroxy-carboxylic acid is added to the epoxidized mixture in an amount sufficient to neutralize any remaining alkali metal hydroxide. The polyols produced in this manner are particularly useful for the production of polyurethane and polyisocyanurate foams.
Patent CA-2218631-A1 (CA)
Inventor: GENZ ANDREAS
IPC: H01J61/12
Filed: 1997-10-20
Abstract: A metal-halide high-pressure discharge lamp (1) with a discharge vessel (2) and two electrodes (4, 5) has inside discharge vessel (2) an ionizable filling, which contains yttrium (Y) in addition to inert gas, mercury, halogen, thallium (T1), hafnium (Hf), whereby hafnium can be replaced wholly or partially by zirconium (Zr), dysprosium (Dy) and/or gadolinium (Gd) as well as, optionally, cesium (Cs). Preferably, the previously conventional quantity of the rare-earth metal is partially replaced by a molar equivalent quantity of yttrium. With this filling system, a relatively small tendency toward devitrification is obtained even with high specific arc powers of more than 120 W per mm of arc length or with high wall loads.  Thus, the filling quantity of cesium can be clearly reduced relative to a comparable filling without yttrium, whereby an increase in the light flux and particularly in the brightness can be achieved.

Title: Method and apparatus for determining a zone in an object exhibiting a highest level of structural organization
Inventor: OSTROVSKY EMIL Y
IPC: G06F17/00
Filed: 1996-02-06
Abstract: A method and apparatus utilizes either a targetless approach or a target oriented approach to determine "attractors" in data fields of a physical property or set of physical properties of an object. A processing system implements the method which begins by first inputting a data field of a physical property or data fields of a set of physical properties of the object. Second, the processing system arranges the data of the data field or the data of each data field into a matrix. Third, the processing system transforms the data within the matrix or matrices to develop transformation matrices. Fourth, the processing system develops a base dichotomy matrix from each transformation matrix. Fifth, the processing system develops a full description set of matrices from the base dichotomy matrices. Sixth, in the targetless approach, the processing system selects the roots of the full description set of matrices and organizes the roots into sequences to provide a representation of a zone within the object exhibiting a highest level of structural organization, or, alternatively in the target oriented approach, the processing system selects the branches to provide a representation of a zone within the object exhibiting a highest level of structural similarity to a target zone within the object of the full description set of matrices. Finally, the processing system displays either the roots in sequences or the branches.

Title: Assembly for deaccelerating a driver in a tool
Inventor: LUCAS DELBERT E
IPC: B25C1/14
Filed: 1996-06-03
Abstract: A tool for driving a nail or other fastener is actuated by a caseless propellant charge (62) formed of combustible material that is transported into a combustion chamber (44) on a strip (64). The propellant charge (62) is ignited by striking a sensitizer portion (90) of the charge at an oblique angle. The ignition member (66) intermixes the sensitizer material (90) with an oxidizer layer (88) of the surface of the propellant charge (62), resulting in combustion of the charge. When ignited, the propellant charge (62) is compressingly interposed between an orifice plate (74) and a movable portion (80) of the combustion chamber. The orifice plate (74) includes a pedestal (78) with an annular compression surface that separates the surface of the ignition area from the remaining surfaces of the charge (62); insuring that ignition gases are forced through the charge (62). An annular C-shaped ring (82) is interposed between the orifice plate (74) and the movable portion (80) of the combustion chamber (44). When the charge (62) is ignited, the resulting gas pressure resiliently expands the annular C-shaped ring (82) and urges opposite axial ends of the C-shaped ring (82) into sealing relationship between the relatively movable components of the combustion chamber.  Combustion gases are communicated through orifices (76) in the orifice plate (74) to a cylinder (40) where the gases force movement of a driver (42), which driver strikes and drives a fastener such a nail. The driver (42) is reciprocally movable within the cylinder (40) and is returned to its precombustion position by a gas spring return cylinder (17). The gas return cylinder (17) is mechanically interconnected to the driver (42) and contains a sealed gaseous fluid that is independent of and segregated from fluids in the combustion chamber (44). An assembly (60) for deaccelerating the driver includes a series of spaced and aligned progressively sized metal cup members (110, 112, 114) of progressively increasing mass, contact surface area and interface angles.

Inventor: POPPLEWELL Andrew
IPC: H03L7/091
Filed: 1999-01-07
Abstract: A phase detector determines an error value dependent on the relative phase between a local oscillator signal, used as the system clock, and an input signal received over a PR (a, b, a) channel. The phase error value is used to control a phase locked loop (Figure 1, not shown). The received signal is sampled at regular intervals dependent on the local oscillator signal. A threshold dicer 22 selects an ideal sample value for a sampling point by comparing the sampled value to three thresholds provided on respective ones of slicer threshold inputs 23, 24 and 25. A subtracter 27 determines a difference value corresponding to a difference between the ideal sample value and the actual sample value for that sampling point. A delay register 28 and a subtractor 29 operate to determine the sense of change to the current ideal sample value from an ideal sample value for a preceding sample point. An output of the subtractor is applied to the switching input of a switch, which thereby provides as an output signal either the difference value or the inverse of the difference value, provided by an inverter 32, dependent on the detected sense of change.
