Abstract: A process for producing a high VI/low volatility lubricating oil basestock and a lubricating oil basestock prepared by said process. The process comprises subjecting the raffinate from a solvent extraction step to a two step, single stage hydroconversion process wherein the first step involves severe hydroconversion of the raffinate followed by a cold hydrofinishing step.

Abstract: A label printer and applicator system which determines the height and position of moving objects on a conveyor while printing labels and positioning the labels for application on the moving objects. The printer/applicator includes a controllable label buffer, applicator actuator and label ejector to receive and apply the printed label, or eject the label when it has been determined that the application to the object cannot be made. Further embodiments include multiple applicators deployed along the conveyor to permit higher conveyor velocities and avoidance of unlabeled objects due to height/proximity relationships with adjacent packages.

Abstract: A method of forming inter-level contacts or vias between metal layers using a tungsten film deposited into the via using non-collimated sputter deposition. The sputter chamber is configured with a pressure of about 1 mTorr to about 10 mTorr with an inert gas flow of at least at least 25 cm3/min to about 150 cm3/min. Shielding inside the chamber is coated with a material, preferably, aluminum oxide, that promotes adhesion of tungsten to the shielding. An adhesion layer of titanium may be included prior to deposition of the tungsten film. Non-collimated sputter deposition increases the target to substrate distance inside the sputter chamber; reduces the heating effect associated with traditional collimated sputtering; and provides more robust diffusion barriers.

Abstract: Disclosed are silicoaluminophosphates (SAPOs) having unique silicon distributions, a method for their preparation and their use as catalysts for the hydroprocessing of hydrocarbon feedstocks. More particularly, the new SAPOs have a high silica:alumina ratio, and are prepared from microemulsions containing surfactants.

Abstract: A method and apparatus are provided for forming a silicide on a semiconductor substrate by integrating under a constant vacuum the processes of removing an oxide from a surface of a semiconductor substrate and depositing a metal on the cleaned surface without exposing the cleaned surface to air. The method and apparatus of the present invention eliminates the exposure of the cleaned substrate to air between the oxide removal and metal deposition steps. This in-situ cleaning of the silicon substrate prior to cobalt deposition provides a cleaner silicon substrate surface, resulting in enhanced formation of cobalt silicide when the cobalt layer is annealed.

Abstract: An instrument for determining a characteristic of a biological fluid or a control includes a radiation-reflective surface, a first source for irradiating the surface, and a first detector for detecting radiation reflected from the surface. A cuvette for use with the instrument holds a sample of the biological fluid or control the characteristic of which is to be determined. The cuvette has two opposed walls substantially transparent to the source radiation and reflected radiation. The first source and first detector are disposed adjacent a first one of said two opposed walls and the radiation reflective surface is disposed adjacent a second of said two opposed walls.

Abstract: Apparatus (10,10') for electric-discharge texturing of a round surface (12) of a roll (14) includes a bank of electrode positioners (32) mounted on a carriage supported housing (30) in axial rows (34) and circumferential columns (36) with the axial rows diverging from a central axis A of roll rotation and with the axial rows symmetrically located on opposite sides of an adjustment axis B along which the electrode positioners are moved by the housing. The adjustment axis B of the housing (30) is inclined upwardly away from the central axis A. The electrode positioners (32) can be provided in an odd number or an even number of axial rows (34) and, in either case, the circumferential columns (36) of the electrode positioners (32) are slightly axially inclined along the central axis A.

Abstract: An electrode positioner (24) for electric-discharge texturing apparatus (10) includes an elongated connector (62) located externally of an elongated housing (32) and extending between a servo head (40) on a slide (38) mounted by the housing and moved by a servo actuator (58). The elongated connector (62) has an internal passage (64) for carrying dielectric fluid to the servo head (40) and also has an electrical connection (60) to the servo head and an electrical connection (70) to an electrical power supply (72) to supply electrical power to an electrode supported by an electrode holder (42) on the servo head. The elongated connector (62) includes an elongated metallic tube (82) whose interior defines the passage (64) that carries the dielectric fluid and which itself carries the electrical power between the electrical connection (60) to the servo head (40) and the electrical connection (70) to the electrical power supply (72).

Abstract: A method and apparatus are provided for forming cobalt on a silicon substrate containing native silicon oxide on the surface thereof wherein a modified vapor sputtering device is used. The vapor sputtering device is modified by providing an electrical circuit to ground whereby the wafer disposed in the device is electrically connected to the ground circuit. The ground circuit preferably contains a resistor therein to control wafer voltage and current flow from the wafer to ground. It has been found that providing a current flow from the wafer to ground and particularly in a ground circuit containing a resistor, provides an in-situ simultaneous cleaning of native oxide on the silicon surface and deposition of cobalt on cleaned silicon. The deposited cobalt containing substrate may then be readily annealed to form cobalt silicide evenly and uniformly across the desired regions of the wafer surface.

Abstract: A delivery system for dispensing controlled amounts of liquid or powder has two slidingly engaged parts which are held together as a single unit. The system is particularly useful for delivering powdered solidifying agents to closed medical waste containment systems. Because medical waste container lids include different sized ports, including relatively large diameter pour spouts and relatively small diameter ortho ports, the delivery system is provided with means for selectively coupling to either pour spouts or ortho ports, vastly increasing the adaptability of the delivery system to given container lids loosed by pushing one of the two parts toward the other until a valve plug in the upper part of the system is received within an aperture of a valve seal membrane in the lower part of the system. The system is opened by pulling one part of the system away from the other using the sliding engagement means so that the valve plug exits the aperture in the valve seal membrane.

Abstract: A delivery system for dispensing controlled amounts of liquid or powder has two slidingly engaged parts which are held together as a single unit. The system is closed by pushing one of the two parts toward the other until a valve plug in the upper part of the system is received within an aperture of a valve seal membrane in the lower part of the system. The system is opened by pulling one part of the system away from the other using the sliding engagement means so that the valve plug exits the aperture in the valve seal membrane. Interior contoured walls prevent undesired collection of powder within the system, the relative orientation of the two parts of the system is adjustable to control the rate of flow of powder, and the system is particularly suitable for introducing powdered desiccants into medical waste containers without exposing the contents of the waste containers to the surrounding environment.
