Title: Production of high viscosity index lubricants
Inventor: DEGNAN THOMAS F
IPC: B01J29/74
Filed: 1991-06-20
Granted: 2003-05-27
Abstract: Petroleum wax feeds are converted to high viscosity index lubricants by a two-step hydrocracking-isomerization process in which the wax feed is initially subjected to hydrocracking under mild conditions with a conversion to non-tube range products of no more than about 30 weight percent of the feed. The hydrocracking is carried out at a hydrogen pressure of at least 1000 psig (7000 kPa) using an amorphous catalyst which preferentially removes the aromatic components present in the initial feed. The hydrocracked effluent is then subjected to hydroisomerization in a second step using a low acidity zeolite beta catalyst which effects a preferential isomerization on the paraffin components to less waxy, high V.I. isoparaffins. The second stage may be operated at high pressure by cascading the first stage product into the second stage or at a lower pressure, typically from 200 to 1000 psig. The second stage catalyst is preferably a noble metal containing zeolite beta catalyst which contains boron as a framework component of the zeolite to give a low alpha value, typically below 10, The second stage is carried out at relatively low temperature, typically from 600 to 650°F with a 650°F+ conversion in the range of 10 to 20 weight percent of the second stage feed but with high selectivity for isomerization of the paraffins. A final dewaxing step to target pour point may be used with relatively low loss, typically no more than 15 weight percent, during this dewaxing. The final products typically have V.I. values in excess of 140 and usually in the range of 143 to 147 and are characterized by exceptional stability.

Title: Connector lock assembly
Inventor: PARSONS GEORGE W
IPC: G21F5/02
Filed: 1991-06-21
Granted: 1999-06-15
Abstract: A coupling apparatus for connecting a separable control cable assembly to a camera storage unit in a radiographic system, having a connector assembly fixed to the camera storage unit and a separable control cable assembly.  The separable control cable assembly is attached to the camera storage unit via the fixed connector assembly for controlling movement of radioactive material attached to a source cable to a desired location outside of the camera storage unit.  The camera storage unit stores the source cable and attached radioactive material in an aperture where the two are locked against removal.  Proper connection of the separable control cable assembly to the camera storage unit releases the source cable and radioactive material from their lock position.  Upon releasing the source cable and radioactive material from their lock position, the control cable assembly is prevented from being removed from the camera storage unit.  The control cable assembly, with a control cable, guides the source cable and radioactive material to a desired location and returns the source cable and radioactive material to their storage position within the camera storage unit, at which time the two are automatically locked in position and releasing of the control cable assembly is enabled.

Title: Portable luminous insect trap
Inventor: JOBIN LUC
IPC: A01M1/20
Filed: 1991-08-29
Granted: 1995-12-26
Abstract: The invention relates to a portable luminous trap for flying or crawling insects. A fluorescent lamp in the center of an insect ingress zone attracts the insects. Transparent baffles radiating outwardly from the lamp act as walls and an insect hitting a baffle is stunned and drops downwardly, through a funnel opening into an entrapment container therebelow. The funnel also helps prevent escape of still-living insects from the container. An alkaline dry cell battery powers the lamp, test circuits for the battery and the lamp, and a clock circuit. A photocell is used to activate the trap at dusk and the setting for the clock circuit determines the length of time that the lamp is activated each night.
