IPC: H04B10/61
Filed: 1987-03-30
Granted: 1990-11-27
Abstract: Abstract:          Pulses from a first laser source at a predetermined high repetition rate are passed through an isolator, mode-matched with an amplifier and then temporally multiplexed to a predetermined high repetition rate.  The high repetition rate pulses are then injected into a second source where they are amplified to derive a stream of high power pulses at the predetermined high repetition rate and then selectively released.

Title: Agitated dewaxing employing modified agitator means
Inventor: BROADHURST THOMAS E
IPC: C10G73/06
Filed: 1987-05-05
Granted: 1991-09-03
Abstract: ABSTRACT OF THE DISCLOSURE        The  filtration  performance  of  a  slurry containing crystallized wax, dewaxed oil and dewaxing solvent is improved by used of an agitator means which possesses a characteristic dimension which when divided by the average wax crystal diameter yields a dimension-less number of about 1,500 or less, preferably about 1,000 or less, more preferably about 500 or less, most preferably about 250 or less.  Use of an agitator means which possess a characteristic dimension yielding a dimensionless number in the range recited above causes a reduction in the size of the vortex generated as the agitator  means  passes  through the slurry during chilling. As a consequence, more intimate contacting of the wax particles during chilling is promoted.         The needed characteristic dimension of the agitator may be obtained in any number of equally acceptable ways.  Single large agitator blades can be replaced by more numerous smaller blades; large blades can be perforated, notched, etc.          Any alteration which causes the agitator cha-racteristic dimension to be reduced so that when it is divided by the average cyrstal wax size the resulting dimensionless number is about 1,500 or less is an acceptable modification.

Filed: 1987-10-27
Granted: 1992-04-14
Abstract: ABSTRACT OF THE DISCLOSURE    Apparatus is disclosed for comminuting heavy fibrous materials, such as tree stumps.  The apparatus includes a cylindrical drum rotor having a fixed impact cutting bar projecting from the drum surface.   The rotor is enclosed in a housing which includes an anvil directing feed into contact with the cutting bar in a primary comminution zone.  The cutting bar strikes the feed material as it is delivered and/or guided by the anvil, producing a partially comminuted product.  The rotor is also partially enclosed by a grate, forming a secondary comminution zone in which the partially comminuted product is confined between the rotor drum surface and the grate.  The grate includes apertures that momentarily restrain partially comminuted particles such that a following cutting bar shears the particle to finished product dimen-sions.  The length of the finished product is determined by cutting bar height, while the cross section of the finished product is determined by grate aperture dimensions.

Abstract: A method is disclosed for making a step-index optical fiber having a steep refractive index gradient between core and cladding.  Core glass particles comprising a base glass and a refractive index-increasing dopant are deposited on a mandrel.  The mandrel is removed and the resultant soot preform is consolidated to form a core preform having a dopant-poor surface  region.   The  core glass preform  is stretched and the hole therein is closed to form a core bait rod.  Cladding glass soot is deposited on the core bait rod at a density which is at least 0.5 g/cc.  This is accomplished  by  directing  the  flame  from  an auxiliary burner onto the  core bait rod  immediately prior to the deposition of cladding soot thereon.  The resultant preform is  consolidated  and  drawn  into  an  optical  fiber.   In another embodiment,  the  etched core preform is  overclad with a layer of cladding glass, and the composite preform is stretched prior to applying a second overclad layer.

In this embodiment, a self-supporting composite is formed typically comprising a boron-containing compound, a carbon-containing compound, and metal.  The relative amounts of reactants and process conditions may be altered or controlled to yield a body containing varying volume percents of ceramic, metal and/or porosity. The mass to be infiltrated can be contained within a refractory vessel having a venting means included therein.
