Abstract: Disclosed herein, in certain embodiments, are composite materials, methods, tools and abrasive materials comprising a tungsten-based metal composition, a tungsten carbide, and an alloy. In some cases, the composite materials or matrix are resistant to oxidation.

Abstract: A medical examination table which is movable between a lowered patient entry/exit position and a raised patient examination position. A scissor-lift assembly is provided to raise and lower the examination table. The examination table includes a drawer having a pivotal front panel which is adapted to support instruments or other items thereon when the drawer is folded to a downward position. The examination table further includes a storage pocket located beneath the backrest. The storage pocket and its contents are concealed when the backrest is lowered and are accessible when the backrest is inclined.

Abstract: A device for use in assisting a person in folding a flag. The device comprises a band having an internal diameter, a first end and a second end and an intermediate extent therebetween. The band is formed into a circular configuration with first and second ends in alignment. A plate is positioned upon the band opposite the first and second ends. A threaded aperture is formed within the plate. A clipping arm is included and has a first end and a second end and an intermediate extent therebetween. A hole is formed within the first end of the arm. A clip is positioned upon the second end of the arm. A hook arm has a first end and a second end and an intermediate extent therebetween. A hole is formed within the first end of the arm. A hook is positioned upon the second end of the arm. A screw is positioned through the hole within the first end of the clipping arm and within the hole within the first end of the hook arm. The screw is threadably secured within the aperture of the plate.

Abstract: Improvements in a downhole submerged pump assembly having a plunger formed of a cast or machined cylindrical member includes seal ring grooves capable of receiving flat metallic seal rings formed of a plurality of segments which are interlocked in a manner wherein the segments can expand during the upstroke of the pump movement and retract during the downstroke.

Abstract: An oil well subsurface pump comprising a housing for reciprocal disposition with a working barrel and having one end thereof adapted to be secured to the lowermost end of a sucker rod, or the like, and the opposite end thereof in open communication with the fluid reservoir in a well bore, a ball check valve carried by the housing and disposed within a ball chamber having a stop at one end for limiting the movement of the ball member in one direction and the opposite end open to the well fluid, resilient sealing assemblies interposed between the outer periphery of the housing and the inner periphery of the working barrel and slidable with respect to the barrel during a pumping operation, longitudinally disposed passageways provided in the housing and extending from the ball chamber to a position beyond the upper limit of the sealing assemblies to provide communication through the housing to the annulus between the housing and the working barrel for passage of the well fluid from the fluid reservoir to the annu

Abstract: A multi-position examination chair for supporting a patient and assuming sequentially a plurality of obstetric and gynecologic examination positions includes a base. A chair mounted on the base includes a back portion pivotally attached to the base and a seat portion pivotally attached to the back portion. A first linear actuator pivotally moves the back portion into a desired position relative the base, and a linkage cooperates to cause a predetermined amount of pivotal movement of the seat portion relative to the base in response to pivotal movement of the back portion. A second linear actuator power means pivotally moves the seat portion into a desired position relative the back portion. Actuation of one of a plurality of switches cooperates with a control system for movement of the back and seat portions from one of the examination positions to at least a next following one of the positions within the sequence.

Abstract: An oil well subsurface pump comprising a housing for reciprocal disposition within a working barrel and having one end thereof adapted to be secured to the lowermost end of a sucker rod, or the like, and the opposite end thereof in open communication with the fluid reservoir in a well bore, a ball check valve carried by the housing and disposed within a ball chamber having one end closed for limiting the movement of the ball member in one direction and the opposite end open to the well fluid, resilient sealing assembly interposed between the outer periphery of the housing and the inner periphery of the working barrel and slidable with respect to the barrel during a pumping operation, longitudinally disposed passageways provided in the housing and extending from the ball chamber to a position beyond the upper limit of the sealing assembly to provide communication through the housing to the annulus between the housing and the working barrel for passage of the well fluid from the fluid reservoir to the annulus f
