Abstract: A process for preparing high VI lubricating oil basestocks comprising hydrotreating, hydrodewaxing and optionally hydrofinishing. The hydrotreated feedstock is hydrodewaxed using a dewaxing catalyst that has been selectively activated by oxygenate treatment. The hydrodewaxed product may then be hydrofinished.

Abstract: An apparatus for receiving metering data from one or more induction electricity meters coupled to an electrical load and/or source of supply and for communicating said metering data to a remote location. The apparatus fits within the existing mechanical package of the induction electricity meter and includes an optical sensing device operably connected to detect the velocity and direction of the induction meter disk. A controller means is coupled to the optical sensing device. The modem transmits metering data to a remotely located receiver upon receipt of a command to transmit.

Abstract: A system for high level dynamic hot code generation. A class file container object is first created. Methods and code are then added to the class file container object. Byte code is then generated from the populated class file container object. From the byte code, instances of the new class object can by generated. The program code generator is configured to generate code at a programming language construct level, thereby working at a level of program language statements, expressions, variables, and other constructs.

Abstract: A dynamic generated wrapper object to intercept transmissions between a vendor object and an application program and performs server side tasks. To dynamically generate the wrapper at runtime in memory, the application server receives a vendor class, performs reflection on the vendor class, generates a wrapper class, and creates an instance of the wrapper class. In operation, the dynamically generated wrapper object receives a call placed to a method of the wrapped object, initiates pre-processing tasks to be performed, calls the method on the wrapped object, receives a result from the method invocation against the wrapped object, initiates post-processing tasks to be performed, and transmits the wrapped result back to the application program. The pre-processing tasks may include execution of a pre-invocation handler. The post-processing tasks may include execution of a post-invocation handler.

Abstract: An impulsive acoustic and radiation source is provided that maintains a constant electrode gap to provide efficient and long life operation. In one implementation the electrodes have a “toaster” arrangement. In another implementation the electrodes have a double annulus arrangement. The electrode gap may be maintained by interposing a non-electrically conducting material between the electrodes. In another implementation the electrode gap is maintain by the insertion of electrodes into a base. Also, the electrodes may be coated with a non-electrically conduction material. In alternative implementation, efficient and long life operation is achieved by feeding a material between widely spaced electrodes. In certain implementations an exothermic material is fed to increase the strength of the impulse from the sparker. Also, reflectors and enclosures are employed that increase the output utilization of the source.

Abstract: A pipe-in assembly comprising an inner pipe unit (7) fixedly mounted within an outer pipe unit (6), each end of the inner pipe unit having a coupling means (3,4) for engagement with a complementary coupling means on an adjacent pipe-in-pipe assembly and arranged such that abutment of in end of the outer pipe unit with an end of the outer pipe unit of aid adjacent pipe-in-pipe assembly brings the inner pipe coupling means of the adjacent assemblies into sealed engagement.

Abstract: An in-band method/apparatus whereby a host is enabled to secure predetermined operational information relative to predetermined ports of a fiber channel switch. A set command is generated at the host and sent in-band to the switch. The information content of the set command defines the ports for which operational-parameters are to be monitored. The information content of the set command also defines which operational parameters are to be monitored. In response to receiving the set command, the switch establishes statistical counters for monitoring port operational parameters in accordance with received operational parameter identifiers. An accept signal is then sent in-band to the host, and a time period of port monitoring begins. After a predefined time period has expired, the host sends a read command in-band to the switch. The switch now generates a monitor record in accordance with the count content of the statistical counters that were established in response to the set command.

Abstract: A pipe connector includes a tubular pin member having a generally frusto-conical outer peripheral surface and a tubular box member having a generally frusto-conical inner peripheral surface corresponding to the frusto-conical outer peripheral surface of the pin member and overlies the frusto-conical surface of the pin member when the members are fully engaged together. The members include with inter-engageable annular projections and grooves on the said peripheral surfaces for axially locking the members together when they are fully engaged together, the projections and grooves being spaced apart along the surfaces. Means are provided for supplying hydraulic fluid under pressure between the overlying parts of the surfaces of the members when fully engaged together to expand the box member and/or contract the pin member to bring the projections out of engagement with the corresponding grooves and permit the members to be disengaged.

Abstract: The present invention provides a divided light inserts which employ metal caming and a kit for mounting the inserts on existing windows. The preferred divided light inserts use substantially lead-free, rigid caming which incorporates a flange and steel core around the perimeter of the insert. The preferred mounting kit provides for ventilation between the insert and the primary glazing panel of a window in which the insert is mounted.

Abstract: A tube assembly for medicament and the like wherein the contents can be discharged by squeezing the tube. The tube assembly includes a nozzle having a discharge port and an axial central bore with a diaphragm extending across the bore at the inner end of the discharge port. A piercer unit mounted in the nozzle portion is mounted for axial movement in the central bore from a first readily position, axially inwardly of the thin wall, to a second discharge position puncturing the diaphragm. The assembly further includes a cap having a support plug sized in the discharge port for abutment against the diaphragm and to prevent inadvertent puncture thereof. The piercer unit includes a hollow needlelike member adapted for movement axially in the central bore and a piston for mounting the hollow needlelike member slidably in the nozzle portion for actuating the needlelike member from the first position to the second position upon application of external pressure, such as squeezing pressure applied to the tube.

Abstract: An automatic focusing mechanism for adjusting the focus setting of the objective lens of an optical instrument such as a photographic camera. The adjustable focusing cell of the objective lens is coupled to a pivotal reception means so that the focus setting of the objective lens is maintained coincident with the distance between the camera and an object to be photographed when the longitudinal axis of the reception means is in alignment with a reflected light beam image transmitted from the camera to the object from an emission means spaced from the reception means. A rangefinder circuit controls the pivotal motion of the reception means so as to maintain its longitudinal axis in alignment with the reflected light beam image through variations in camera-to-object distance.

Abstract: A photographic apparatus having a lens movable along an axis for automatically focusing an object to be photographed is disclosed. The apparatus includes a rotatable sleeve controlled by electrical signals produced by photoreceptor means adapted to receive light emitted by the apparatus and reflected from the object. The sleeve effectuates the movement of the lens along an axis to bring the object into focus. The apparatus further includes assembly means, carrying the photoreceptor means, pivotably secured to the sleeve for adjusting the light received by the photoreceptor means by an amount corresponding to the rotation of the sleeve, thereby changing the electrical signals to maintain the object in focus.
