Abstract: ABSTRACT           A self powered downhole tool anchor device (10) preattached to a downhole tool (T) and unitarily supported by a drill string (DS) for a single trip into a well bore, actuated by forceful engagement with the bottom or plug (P) in the well bore and attachment to a well bore casing (C).          The anchor device comprises an inner mandrel (20) and lower cone (34) containing a piston (30) and fluid (F) for axially displacing an outer mandrel and piston (44) connected thereto by shear screws (46).  An upper cone (20) on the outer mandrel is connected by shear pins to a slip housing (50) containing radially expandable slips (38) keyed to the lower cone (34).  A self contained Power supply (PS) of combustible material (M) is ignited by a firing pin (90) striking a primer igniter (I) and generates gas pressure applied to the piston 30 and fluid (F) to shear pin (46) and axially displace the outer mandrel and piston (44) upper cone (40) slip housing (50) slips (38) and ratchet ring (62) relative to inner mandrel (20) and cone (34).  Screws (52) are then sheared off releasing upper cone (40) from slip housing (50) and allowing relative displacement therebetween to radially expand slips (38) into gripping engagement with the well bore casing (C).  A mechanical firing mechanism includes a preloaded compressed spring(l00) actuated hammer (98) retained against a spring housing (102) and in a cocked firing position by a shear pin (101) extending from an outer housing (96). A trigger (108) engaged by the spring housing (102) has a foot (110) which engages the bottom of or plug (P) in the well bore.  Lowering of a predetermined amount of weight of the assembled unit causes pin (101) to shear and release the hammer (98) which strikes and propels the firing pin into the igniter capsule I.

Abstract: ABSTRACT OF THE DISCLOSURE         The device comprises a cylindrical crusher housing mounted on a carriage above a removable wastebucket, which communicates with a funnel-shaped discharge formed in the lower end of the housing.  The top of the housing is sealed by a cover which has a lamp inlet opening and an exhaust opening.          The shaft of an electric motor extends into the housing and has secured thereto a plurality of flails or crusher elements which rotate at high speed; adjacent the inlet opening to strike and crush lamps entering the nousing.  The exhaust opening is connected by a duct to a filter cartridge which is removably mounted on the exterior of the crusher housing above an exhaust fan.  The cartridge contains a porous filter bag, which is removably attached to the exhaust duct, and an activated charcoal filter element, which is positioned in the cartridge beneath the bag and in communication with the fan inlet.  The exhaust fan operates simultaneously with the crusher motor to develop a vacuum which draws exhaust air from within the housing successively through the filter bag and the charcoal filter element.  The filter element is specially treated to remove mercury vapor from the exhaust air that passes through the element.

Abstract: ABSTRACT OF THE DISCLOSURE       Chemical biological agents to be encapsulated are dissolved or dispersed in an aqueous paste of a gel-forming polyhydroxy polymer.  Subsequent addi-tion of boric acid or a boric acid derivative at an alkaline pH converts the paste into a gel, thereby entrapping the agents in a protective matrix.  En-capsulation of biologically active compositions pro-vides a shield against hostile environments, improves safety in handling, and alows the release of such compounds to the surrounding medium.  Highly volatile liquids are protected against losses by evaporation. Encapsulation also provides protection against de-composition from exposure to ultraviolet light.

Abstract: Abstract of the Disclosure The heat exchanger disclosed herein includes a head section and a heat exchanging section.  The heat exchanging section consists of a bundle of inner conduits, open at both ends, and a bundle of outer conduits open only at one end.  The outer conduits enclose that part of the inner conduits within the heat exchanging section, such that an annular space is defined between the conduits.  In operation, a lower temperature fluid is introduced into the head section, which generally operates at low temperature and high pressure.  The lower temperature fluid flows through the inner conduits into the heat exchanging section and returns to the head section through the annular spaces between the inner and outer conduits.  The high temperature fluid flows through the heat exchanging section in intimate contact with the conduits containing the lower temperature fluid, so that it is cooled by the lower temperature fluid.  The head section of the heat exchanger is protected against the high temperatures in the heat exchanging section by a temperature adjustment zone, which thermally separates the head and heat exchanging sections.

Abstract: METHOD AND APPARATUS FOR HEAT SEALING PLASTIC MEMBERS     Abstract of the Disclosure A heat sealing apparatus for bonding plastic tubular members includes a seamless, tubular, elastic heating element encircling the plastic members.  In one form, an annular inflatable bladder filled with hydraulic fluid encircles the heating element, and includes a rigid outer wall and an elastic inner wall that is bonded to the outer surface of the heating element.          When the bladder is pressurized the heating element is compressed inwardly to a bonding position against the plastic members.  The plastic members are then heated to a bonding temperature by the heating element resulting in a fusion bond along their interface.  When the bladder is evacuated the heating element opens outwardly to be spaced from the plastic members to allow removal of the sealed members.  The heating element includes a uniform dispersion of susceptor particles that will generate heat when exposed to the high frequency magnetic field of an induction heating coil.
