Abstract: A well clean out tool installed in a drill string is operable to pump sand and debris from the well bore.   A pump portion  includes  an  elongate  pump  barrel  having  apertures extending through  its  side wall at the upper end which is attached at its bottom end to one or more the debris-receiving and trapping subs and enclosed at its upper end by a top cap having a hexagonal opening.   A hexagonal pump mandrel extends through the top cap and is connected to the bottom of the drill string by a top sub having apertures through its side wall whereby the pump barrel may be rotated with the drill string.  A swab assembly contained within the pump barrel and connected to the bottom end of the pump mandrel is reciprocated thereby.  The swab assembly includes a cruciform swab bypass mandrel having longitudinal fluid bypass channels with stop shoulders at each end thereof.   One  or more  swab cups having internal metal sleeves ride on the exterior of the bypass mandrel.  On the down stroke, the swab bypass mandrel moves down relative to the swab cups to allow passage of fluid through the bypass channels and the apertures in the pump barrel and the valves in the lower subs close to capture sand and debris in the subs.  On the up stroke,  the bypass mandrel moves up and the lower swab cup closes off the bypass channels.  As the swab assembly is raised relative to the pump barrel, the valves open allowing sand and debris to enter the lower subs and the fluids within the pump barrel are discharged are discharged through the pump barrel outlets.

Abstract: A cantilevering support arm is provided for supporting a suspended load and for encasing utility supply conduits to enable various activities requiring access to such utilities to be carried out at a distance from a structure supporting the arm.  When used in association with welding operations for example, the arm may support a welding wire feeder, welding gun, and coil of consumable welding wire.  A battery of utility outlets may be positioned at the outer end of the arm providing access to compressed air, fume and dust extraction, and electrical power.  All utility conduits such as electric welding power supply conductors, air hoses, extraction ducts and electrical control conduits may be encased within the arm to protect them from damage, remove the hazard posed by conduits laying upon the shop floor and to provide for simple access to multiple utilities at a distance from the utility sources.  The arm comprises an inner boom pivotally mounted to a stationary supporting structure, an outer jib, and a knuckle pivotally joining the boom and jib.  The boom, jib and knuckle are operable in a horizontal plane to provide access to utility connections at the outer end of the jib within an arc envelope defined by the outer extent of the arm.

Abstract: ABSTRACT            Bright and undimmed lights of motorized vehicles reduce a driver's ability to see oncoming traffic and his own side of the road, especially when driving in the rain at night.  A filter with a unique shape is strategically placed between the light of the oncoming traffic and the eyes of the driver.  The filter reduces the intensity of the lights and the glare they produce, enabling the driver to see both, the oncoming traffic and his/her own side of the road more clearly.  The filter can also be used to reduce undesirable effects of sunlight and its glare.

Title: Conversion of light hydrocarbons to ether rich gasoline
Inventor: BELL WELDON K
IPC: C10L1/182
Filed: 1991-04-10
Abstract: Abstract A process is disclosed for converting a light hydrocarbon feedstock that contains a mixture of linear and branched olefins to ether-rich high octane gasoline streams that include tertiary alkyl and isoalkyl ethers such as MTBE, TAME, methyl isopropyl ether (MIPE), and methyl sec-butylether (MSBE). The process involves initially etherifying the tertiary olefins with a lower alcohol in the presence of an ion exchange resin catalyst, and then etherifying the linear olefins in the presence of a zeolite catalyst, such as zeolite beta. The unreacted olefins from the etherification reactions are converted to gasoline boiling range hydrocarbons by oligomerization with a zeolite catalyst, such as ZSM-5.
