Title: Improved structure two-level ceiling lamp frame junction box
Inventor: WU WEN-CHANG
IPC: F21V21/03
Filed: 2002-01-03
Granted: 2008-04-22
Abstract: An improved structure two-level ceiling lamp frame junction box comprised of pendant fixtures having an upper peg-ended rod at their top ends that are press fitted into a ceiling mount and a lower plug-ended rod below that are socketed into a junction box. The junction box has a plurality of installed sockets, a retaining element is hinged to the two sides of each socket, and a flat spring is fastened to the top end of each socket to engage the lower plug-ended rods. A coil spring is respectively hooked onto notched nibs at the top ends of each pair of retaining elements, which control the extension and retraction of the coil spring. The upper peg-ended rod of each pendant fixture has a ball end that is pushed through a coupling spring an appropriate degree until the coupling spring rebounds and clips onto it, while the said lower plug-ended rod is tipped with a male fitting that is engaged by a snap-fit spring at the bottom face of the flat spring. As such, the upper peg-ended rods and the lower plug-ended rods are directly installed into the ceiling mount as well as the junction box and no additional fasteners or tools are required, thereby facilitating convenient assembly.

Title: A method of imparting stain resistance to a differentially dyeable textile surface and the article produced thereby
Inventor: BAUMANN MARKUS
IPC: D06B3/10
Filed: 2000-07-07
Granted: 2010-10-19
Abstract: A method of treating articles having a textile surface (such as broadloom carpets or carpet tiles) with a stainblocker composition is disclosed. In one embodiment a pile surface structure having pile elements containing nylon yarns having both acid dyeability and cationic dyeability is dyed with both acid dye and cationic dye and then passed through a hot stainblocker treatment bath and cooling zone. Substantially the entire height of each pile element is coated with a stainblocker composition whereby the pile surface structure has a stain resistance of 9 or higher on the AATCC Red 40 Stain Scale. The resulting pile surface has good color separation and stability, and no color loss from the catatonically dyeable yarns. In another embodiment, after coloring, a stainblocker composition having a temperature from twenty to ninety-five degrees Celsius (20 to 95 °C) is applied. If the articles are carpet tiles, the stainblocker is applied using a flood process. The article is dried in a drying zone having a temperature in the range from seventy-five degrees Celsius to ninety-five degrees Celsius (75-95 °C) for a time sufficient to allow the stainblocker composition to react with the nylon yarn in the textile surface. Preferably, in infra-red oven is used to define the drying zone.

Abstract: A parabolic modulation circuit multiples a horizontal parabolic signal and a vertical modulation signal together, to amplitude-modulate the horizontal parabolic signal using the vertical modulation signal, and modulates the phase of the horizontal parabolic signal on the basis of the vertical modulation signal, to output the modulated horizontal parabolic signal to a correction current output amplifier.      When an NS pincushion distortion on a screen of a CRT is asymmetrical, a horizontal parabolic signal generation circuit is so set as to generate an asymmetrical horizontal parabolic signal. A gull-wing distortion can be corrected by adjusting the value of n in an n-th power waveform generator in the horizontal parabolic signal generation circuit.

Abstract: A range hood having an improved grease collecting motor housing and improved fan and motor connection. Housing openings are defined by circular walls projecting vertically into the housing acting to collect grease within the housing. A flange depends radially outwardly from, and at an angle to, the circular wall. Air entering the housing via the fan deflects off the flange and prevents turbulent air within the housing from exiting the housing in the space located between the circular wall and the fan. The fan connection is comprised of a threaded recess in a shaft of the motor and a fan cap having a threaded bolt. The shaft is inserted through an aperture in the fan and the fan cap threadingly connected to it. A tray attachable to the housing, and defining an air intake opening has an improved mating relationship with a lower panel of the range hood.

Abstract: A plunger lift for a hydrocarbon well includes a multipart piston that is dropped into the well in separate pieces. When the pieces reach the bottom of the well, they fall into an accumulation of the formation liquid in the bottom of the well and unite. Gas from the formation pushes the unit upwardly, pushing liquid above the piston toward the surface. The multipart piston includes a upper sleeve and a lower component. A decoupler at the surface comprises a separator rod which the sleeve passes onto thereby dislodging the lower component and allowing it to fall into the well. The sleeve is held on the separator rod by the action of well contents flowing around and/or through the sleeve. When well flow around the sleeve is interrupted, the sleeve falls into the well. The length of time the sleeve is held at the surface is varied in response to the amount of liquid produced on each cycle.
