Abstract: The pumping or swabbing device and apparatus of the invention utilizes an elongate barrel slidable upwardly and downwardly on an axial rod which carries a valve element for closing on a valve seat provided interiorly of the barrel to close passage through the barrel of down-hole pressure fluid and cause such fluid to raise barrel and rod of the device through a gas and oil well casing to the wellhead, where liquid above the device is pushed to discharge at the wellhead. Spring actuated detent latching elements coact with a pair of longitudinally spaced lower and upper latching recesses to hold the barrel and rod together against relative movement in lower valve-closed and upper valve-opened positions. A sealing packer encircles the barrel and a by-pass passage thereinto leading from and back into the barrel flow passage provides sealing pressure within such packer as the device rises in the well casing. A manually or pressure operated latch provides for holding the device in the wellhead as desired.

Abstract: A platen for use with a conventional screen printing machine for printing designs or patterns onto garments includes a window or windows formed in the body of the platen. The windows permit backlighting therethrough and through the garment material to enable the positioning and registration of a pattern on one side of a garment (the front side, for instance) to be registered with a pattern to be printed on the opposite side of the garment. The platen windows may be formed of a plexiglass material, either transparent or translucent, sufficient to permit light to pass therethrough. Light sources are positioned directly below the windows of the platen to enhance the backlighting effect for more accurate registration of patterns to be printed on the garment. A closed loop frame is adapted to fit around the periphery of the platen to hold a garment in position on the platen during the screen printing process.

Abstract: For sequentially dispensing individual closed loops of a narrow, easily tied, flexible material, such as dental floss, a chain having such closed loops as respective links thereof is made up by pressing a loop length of the flexible material into substantially rectilinear formation, loosely forming a knot in an end thereof, inserting a loop end of another so-pressed loop length into the loosely formed knot of the first loop length, tightening the knot to provide a slip-free-until-pulled-to-separate-loops joinder between the thus formed loop links and repeating this with additional loop lengths at either or both ends of the first-joined loop length until a chain of desired length is formed. Individual loop links are dispensed by grasping a terminal loop link of the chain and pulling it free of the chain while holding the knot that embraces the unknotted end of the next loop link of the chain.
