Abstract: An ink jet printhead-priming cap includes a first expanse having a peripheral lip region for sealingly engaging an ink jet printhead. The first expanse has formed therein an aperture through which ink can be drawn. Flexible sidewalls are connected in a first region thereof with and extend from the first expanse. The sidewalls extend continuously around a perimeter of the first expanse. A second expanse is connected with a second region of the sidewalls to form a substantially sealed chamber of nominal volume into which ink can be drawn. The second expanse has generally centrally located structure therein for matingly engaging a piston. The flexible sidewalls enable the volume of the chamber alternately to be decreased and increased by piston action thereby to prime the printhead by producing relatively reduced pressure in the chamber to draw ink thereinto from the printhead with the printhead sealingly engaged by the lip region.

Abstract: A compressor having a discharge valve. The discharge valve is mounted to the fixed scroll of a scroll compressor using a C-shaped clamp. The clamp is secured using a threaded fastener which extends through the clamp at a position between the two legs of the clamp. The valve member is positioned within a recess on the scroll member and sealingly covers a discharge outlet through which compressed refrigerant is discharged from the working space of the compressor. The thickness of the scroll member at the location of the discharge outlet is less than the thickness of the scroll member at the location where the threaded fastener attached the clamp to the scroll member. The valve member is larger than the discharge outlet and the recess is dimensioned to limit the movement of the valve member such that it remains positioned over the discharge outlet.

Abstract: An electro chemical conversion cell that can break down certain gasses to provide ozone and monovalent oxygen from a supplied volume of a suitable O2-containing gas. The conversion cell is provided with at least one metal mesh electrode within a generator reaction chamber, and a power supply which is adapted to supply a high alternating electric current voltage to at least partially break-down O2 in the input gas to yield ozone. A fluid flow passage extends through the reaction chamber as a generally elongated passage through the reaction cavity. The fluid flow passage extends from an upstream end, where the O2-containing gas is initially supplied into the housing, to a downstream end where treated gas either flows outwardly therefrom under pressure or is evacuated from the housing. In a simplified construction, the fluid flow passage is delineated by a series of electrically insulating plates and/or spacers which are used to partition the reaction cavity.

Abstract: Apparatus, and an associated method, having a packet zone list timer embodied at a mobile node operable in a packet radio communication system. The packet zone list timer provides hysteresis to reduce the possibility of a ping-pong effect when a mobile node is operated at, or crosses, a packet zone boundary.  A timer value used by the packet zone timer is selected at the mobile node without the need for network-generated commands to notify the mobile node of the timer value. Comparisons are made at the mobile node, and determinations are made at the mobile node as to whether registration of the mobile node is required.

Abstract: L'invention concerne un appareil et un procédé permettant de recevoir des signaux de modulation en couches. Un procédé typique consiste à recevoir un signal de modulation en couches (602) comprenant un signal de couche supérieure et un signal de couche inférieure, à démoduler et à décoder (604) le signal de couche supérieure à partir du signal de modulation en couches reçu, à estimer un facteur d'amplitude de couche supérieure et un facteur de phase de couche supérieure (618) à partir du signal de modulation en couches reçu. Un signal de couche supérieure pratiquement idéal est reconstruit à partir du signal de couche supérieure décodé et démodulé. Pour ce faire, une amplitude idéale et une phase idéale (620) sont synchronisées par application du facteur d'amplitude de couche supérieure et du facteur de phase de couche supérieure au signal idéal reconstruit de couche supérieure. Finalement, le signal reconstruit idéal de couche supérieur est soustrait du signal de modulation en couches reçu (622) de manière à produire le signal de couche inférieure à traiter.

Abstract: The pump has a barrel with vent ports located therein and a plunger that reciprocates inside the barrel. The barrel has a standing valve and the plunger has a traveling valve. The plunger has a first portion with a seal between the plunger and the barrel and a second portion with a clearance between the plunger and the barrel. On the downstroke, gas contained in the compression chamber between the two valves vents through the clearance and out of the barrel through the vent port into the well bore. When the plunger contacts liquid in the compression chamber, the liquid enters the clearance and forms a seal, wherein the plunger traveling valve opens. The plunger can also be equipped with a second traveling valve and a vent in the plunger between the two traveling valves in order to equalize pressure across the first traveling valve at the bottom of the downstroke. This enables the standing valve to open much faster on the upstroke.

Granted: 2009-06-02
Abstract: The terminal block assembly of this invention provides a finger safe method of distributing power while at the same time enabling the installer to make uniform and correct connections to a multiplicity of taps or ports. Each connection includes an abutment to engage the end of the conductor. The construction of the block and its insulating case provides the visual access to the tip of the conductor in its seated position before the conductor is secured to the block with clamp screws. The entire top of the insulating case is made from a transparent material. The top is provided with interior projections serving both to gauge and limit retraction of some of the clamp screws to prevent loose screws in the case. The screws, even though fully retracted or disengaged from the block, are held in axial alignment with their respective sockets and can't become loose in the case.
