Title: Incremental pressure-compensating drip irrigation emitter
Inventor: ECKSTEIN GERSHON
IPC: B05B1/30
Filed: 1992-02-25
Abstract: An outer wall member, such as the wall of a tube, connectable to or integral with the pipe, has an opening in communication with the exterior of the pipe. An inner member is fixedly positioned against the inside of the outer member for separating the opening from the fluid path through the pipe. The inner member has an inner surface defining at least a portion of an inner chamber in communication with the pipe fluid path. The inner and outer members define a labyrinth having an effective cross-sectional area, an inlet end for receiving pressurized fluid from the pipe, and an outlet end in communication with the pipe opening for emitting fluid. A plurality of channels couple intermediate portions of the labyrinth directly to the opening, thereby bypassing respective parts of the labyrinth. A resilient wall, functioning as a valve, forms a barrier between the channel and the inner chamber and is responsive to the pressure in the inner chamber for restricting the channel when the pressure exceeds a first predetermined pressure. This prevents the fluid from bypassing part of the labyrinth, increases the effective length of the labyrinth, and thereby reduces the flow that takes place at the higher pressure.

Title: Free-electron laser oscillator for simultaneous narrow spectral resolution and fast time resolution spectroscopy
Inventor: MADEY JOHN M J
IPC: H01S3/09
Filed: 1990-08-20
Abstract: A technique for increasing the temporal resolution of the optical pulses white simultaneously increasing the spectral resolu-tion of the pulse train in a free-electron laser. The increase in temporal resolution is achieved by introducing a quadratic temporal phase variation (i.e. linear frequency chirp) across the optical pulses, and then propagating the outcoupled pulses through a dis-persive delay line such as a grating pair or prism pair in order to compress them to the transform limit of the broadened spec-trum. Essentially, the quadratic time dependence of the optical phase broadens the spectrum and yields Fourier components whose phase exhibits a quadratic frequency dependence. To operate a free-electron laser in such a configuration, electron micro-pulses with a linear time-dependent energy are produced in the RF linac by positioning the bunches slightly off the peak of the RF wave at phases where the field gradient is large. These electron micropulses are injected into the wiggler and lead to the for-mation of optical pulses with a corresponding linear time-dependent frequency.

IPC: G06F11/16
Filed: 1992-05-19
Abstract: A shared-buffer-memory-based ATM switch module (1) is duplicated (2) and operates in active-standby mode for fault-tolerance. Following failure and repair of a module, buffer memory (12) contents of the two modules are resynchronized as follows. At the time of commencing the synchronizing, contents of the memory of the standby, repaired, module are cleared, all writes to the active module's memory also commence to be made to the standby module's memory, and track begins to be kept of overwriting of the contents of the active module's memory that existed at the time of commencing the synchronizing. This is done by a function (FIG. 4), whichsets a flag (64) in a queue-length-counter monitor (60) for every active-module queue-length counter (200) that reaches a count of zero to indicate that its corresponding buffer-memory queue (100) has been emptied. When all monitor flags have been set in response to each queue-length counter having reached a count of zero, it indicates that the original contents of the active module's memory have been overwritten and the memories again have identical contents, and consequently that resynchronization of the two memories has been achieved and fault-tolerancehas been re-established.

Title: Isotopically-pure carbon-12 or carbon-13 polycrystalline diamond possessing enhanced thermal conductivity
Inventor: BOVENKERK HAROLD P
IPC: B01J3/06
Filed: 1992-06-04
Abstract: DIAMOND POSSESSING ENHANCED THERMAL CONDUCTIVITY                ABSTRACT OF THE DISCLOSURE Broadly, the present invention is directed to polycrystalline diamond of improved thermal conductivity. The novel polycrystalline diamond consists essentially of at least 99.5 wt-% isotopically-pure carbon-12 or carbon-13. The inventive polycrystalline diamond is formed from at least 99.5 wt-% isotopically-pure carbon-12 or carbon-13. Single-crystal isotopically-pure carbon-12 and carbon-13 diamond are known to possess improved thermal conductivity. Polycrystalline diamond, however, possesses lowerthermal conductivity patterns deleteriously impacted by, for example, impurities, isotopic effects, and grain boundary scattering. In fact, grain boundary scattering would lead the skilled artisan to believe that the thermal conductivity of polycrystalline diamond would be substantially unaffected by the isotopic nature of the diamond itself. Unexpectedly, however, isotopic effects were discovered to predominate in impacting the thermal conductivity of polycrystalline diamond consisting essentially of isotopically-pure carbon-12 or carbon-13. This is true whether the isotopically-pure polycrystalline diamond is grown directly or whether individual isotopically-pure carbon-12 or carbon 13 diamond crystals are subjected to sintering for forming a polycrystalline structure, e.g. layer or compact, thereof.

Title: Method and apparatus for spatially resolved thickness mapping
Inventor: MOORE CHRISTOPHER J
IPC: G01B11/06
Filed: 1993-01-07
Abstract: ABSTRACT     Improved interferometric methods for mapping the variations in the thickness of a thin dielectric film or layer at a large number of sites are described.  A scanning optical measurement apparatus is used to obtain the measurements required for the methods of invention.  Infrared light is applied to a thin layer, and the interference fringes due to a single wavelength of light are sampled to provide a map of the monochromatic reflectance of the thin layer.  The monochromatic reflectance map is analyzed, and a small number of sites are selected according to the methods of the invention for absolute thickness determination by known methods.  The interference order is determined for each one of the small number of sites from the determined absolute thickness values.  The interference order and monochromatic reflectance are then used to calculate the thickness of the thin layer at other sites.  This process allows large numbers of thickness determina-tions to be made quickly.  Real data, containing noise and dis-tortions, can be processed by the methods of the invention.
