Title: Process for imaging of liquid photopolymer printing plates
Inventor: CASALETTO NICOLA
IPC: G03F7/00
Filed: 1995-08-18
Abstract: A method for curing a photosensitive resin composition includes use of an especially thin gauge protective cover film, preferably incorporating a coating to permit ease of removal after imaging. The method also uses a photosensitive resin composition incorporating a photospeed modified capping layer to selectively retard image growth during exposure. To eliminate undesirable defects in the cured photopolymer, a glass plate which had previously contacted and flattened the composition, is separated from the composition by at least 0.064 cm (at least 0.025 inches) after partially curing the composition but prior to completely curing the composition. The partial cure of the composition is achieved by directing light to the composition from a source of actinic radiation positioned about 15.2 cm to about 76.2 cm (about 6 to 30 inches) from the resin composition, where the actinic radiation has a wavelength of maximum intensity of about 365 to about 375 nm.

Title: Method and apparatus for manufacturing a rock bit leg
Inventor: DAVIES PETER M
IPC: E21B10/20
Filed: 1995-09-11
Abstract: A method of manufacturing a rock bit leg from a rough bit leg forging is disclosed whereby multiple machining operations are performed by a six-axis CNC machining center. Three dimensional datum surfaces are initially formed on a rough leg forging. The rough leg forging is then mounted in a holding fixture. The fixture, including the leg forging, is secured to the six-axis CNC machining center. A three dimensional datum reference from the leg forging is set into the NC function of the six-axis machining center.      The rough leg forging includes a pair of extended flanges coincident with the 120° leg surfaces. The leg flanges mount to complimentary surfaces formed on the leg holding fixture, thus securing the leg within the fixture without interference of any of the machining processes.      The CNC machining center performs a majority of the material removal operations to prepare the leg for subsequent assembly through manipulation of the six interactive axes of the CNC machining center. The machining center positions the rough forging of the rock bit leg in any and all attitudes necessary to accomplish each of the separate material removal operations thereby maintaining extremely close tolerances since the leg forging remains indexed to and secured within the fixture throughout all of the machining processes.

Title: Alignment laser with over-flooded aperture system and dual-mode self-centering target
Inventor: HAMAR MARTIN R
IPC: G01B11/27
Filed: 1996-02-21
Abstract: A device for aligning and measuring a hollow, rotatable bore includes a laser beam source within a housing having an aperture in its front face for passing the beam. The housing is mounted at one end of the extruder bore to project the beam through the bore to be detected by a target at the opposite end.     The diameters of the aperture and bore are concentric and the laser beam defines an axis that is alignable with the axis of rotation of the rotatable member, using target signals, by vertical and horizontal displacement with micrometers disposed on the rear face of the laser housing. Various arrangements for mounting the housing on the extruder are disclosed. The target includes a sensing cell in a housing mounted in an adapter with four balls disposed on its periphery 90° apart. The housing orients the cell plane coincident with the plane of the four balls and the diameter at the four balls is dimensioned to exceed that of the bore to be measured so that the target member when tilted and inserted into the bore will jam into place at an angle. The four balls can be urged into contact with the inside diameter of the bore, resulting in a target that is self-centered. In another mode, the housing may be moved so that the cell plane is perpendicular to the axis of the bore to permit the diameter of the bore to be checked.

Title: System and method for the extractment of physiological signals
Inventor: TIEN JONATHAN
IPC: G06F17/00
Filed: 1996-05-15
Abstract: A technique for the accurate determination of artifact free pulse oximetry signals utilizes an adaptive signal processor and peak detector circuit. A reference signal for the adaptive signal processor is derived based on mathematical relations of the detected light signals and the true intensity of light signals. The derivation of the appropriate reference signal requires the determination of peak values for two ratio constants. The two ratio constants lie within a known physiological range of values. When the value of the ratio constants has been determined, the reference signal equals the true intensity. The output of the adaptive signal processor is provided to the peak detector. The peak detector subdivides the known physiological range into two intervals and determines in which interval a peak exists. The remaining interval is discarded, and the peak detector repeats the measurement on the remaining interval until a peak has been detected within the desired accuracy. The value corresponding to the detected peak is one of the ratio constants. In a second alternative embodiment, the output of the adaptive filter is fed directly to the peak detector to determine values for the two ratio constants. In yet a third embodiment, two adaptive signal processors are coupled to a ratio processor. The output of the ratio processor is at a minimum when the appropriate value is selected for each of the two ratio constants.

IPC: G02B1/14
Filed: 1995-03-01
Abstract: An abrasion wear resistant coated substrate product is described comprising a substrate and an abrasion wear resistant coating material comprisisng carbon, hydrogen, silicon, and oxygen.  The abrasion wear resistant coating material has the properties of Nanoindentation hardness in the range of about 2 to about 5 GPa and a strain to microcracking greater than about 1 % and a transparency greater than 85 % in the visible spectrum.  The coated products of the present invention are suitable for use in optical applications such as ophthalmic lenses or laser bar code scanner windows.  In the method for making the products, the substrate is first chemically cleaned to remove contaminants.  In the second step, the substrate is inserted into a vacuum chamber, and the air in said chamber is evacuated.  In the third step, the substrate surface is bombarded with energetic ions and/or reactive species to assist in the removal of residual hydrocarbons and surface oxides, and to activate the surface. After the substrate surface has been etched, a protective, abrasion-resistant coating is deposited by plasma or ion beam deposition.  Once the chosen thickness of the coating has been achieved, the deposition process on the substrates is terminated, the vacuum chamber pressure is increased to atmospheric pressure, and the coated substrate products having improved abrasion-resistance are removed from the vacuum chamber.
