Title: Piezoelectric lighter which has a higher level of difficulty for operation
Inventor: MEURY MARCEL
IPC: H01L41/113
Filed: 1997-12-17
Granted: 2004-04-27
Abstract: The piezoelectric ignition mechanism (10) of the present invention has a telescopic assembly having an inner (14) and an outer (12) members aided by a return spring (16) for maintaining a maximum extension between the members. The inner member includes a piezoelectric element (24) which is immobilized between an anvil (22) and impact pad (26) over which a plexor (28) strikes to generate a spark. An impact spring (30) for aiding the plexor is guided in the interior of the telescopic assembly and is disposed between the plexor and an end member connected to the outer telescopic member. A resistant spring (50) is also disposed at or near the end member to provide additional resistance to the operation of the piezoelectric mechanism in order to discourage the undesirable operation by young users.

Title: Gas diffusion electrode with reduced diffusing capacity for water and polymer electrolyte membrane fuel cells
Inventor: SCHWESINGER THOMAS
IPC: H01M8/1004
Filed: 1998-03-06
Granted: 2008-01-29
Abstract: Gas diffusion electrodes (1) for polymer electrolyte membrane fuel cells are modified such that the diffusion of water therein is inhibited in comparison with unmodified electrodes. Polymer electrolyte membrane fuel cells with the modified gas diffusion electrodes can be operated, with on the average unchanged operating conditions, without addition of water, since the gas diffusion electrodes do not allow more water to escape than that formed during the reaction of burnable gas and oxidizing agent, and guarantee sufficient membrane moisture.

Title: Method and arrangement for locking in a yig-tuned oscillator
Inventor: SCHEFFOLD BRUNO
IPC: H03L7/16
Filed: 1998-04-09
Granted: 2002-09-10
Abstract: The object of the invention is to provide a lock-in process and device for a  YIG-tuned oscillator which takes into account ageing and hysteresis of the Y IG- tuned oscillator. This object is attained in that during a predetermined frequency change, the frequency of the YIG-tuned oscillator (1) is preset by  means of a microprocessor (17) that progressively changes the current (ISP) in the main tuning coil (13) of the YIG-tuned oscillator (1) by an iterative capture routine, until the capture range (.DELTA.FM) of the switched-on frequency-locked loop, which changes with the coil current (ISP), includes t he new operating frequency (fSET). The switched-on frequency-locked loop then pulls the oscillator frequency into the capture range of the PLL and the PLL  locks-in the oscillator frequency to the new operating frequency (fSET). The  microprocessor (17) interrupts the capture routine when a PLL-LOCK detector (11) announces to the microprocessor (17) that the new operating frequency (fSET) has been successfully locked-in. The invention is used in a process f or locking-in a phase-locked loop (PLL) to a YIG-tuned oscillator whose frequen cy is brought into the PLL capture range by a frequency-locked loop equipped wi th a frequency discriminator. When the PLL is locked-in, the frequency-locked loop canbe switched off.

Inventor: KORT MICHAEL E
IPC: C07D237/18
Filed: 1998-08-10
Granted: 2007-04-17
Abstract: The present invention describes pyridazinone compounds of formula III, which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX/2), COX-2 us the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important "housekeeping" enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marked non-steroidal anti-inflammatory drugs (NSAIDs).

Abstract: Objective lenses for endoscopes are made substantially of sapphire. The high refractive index of sapphire results in optical components with shallower curvatures, leading to smaller geometric aberrations, and consequently fewer components are required to correct for these aberrations, Chromatic aberrations are less severe because of sapphire's low dispersion. The objectives may be either of the landscape or retrofocus type, and are compact with moderate field of view, low f-number, and less distortion than most conventional designs.

Title: Structured voicemail messages
Inventor: BALL THOMAS J
IPC: H04M3/493
Filed: 2000-05-04
Granted: 2003-07-29
Abstract: A sender (101) creates a voicemail message that includes a plurality of messaging elements that include embedded instructions that define a structure of the message. Other messaging elements may include textual fragments, audio fragments that refer to audio data files that are associated with the message, and/or references to textual fragments and/or audio fragments that are stored at specified locations. The instructions may define a hierarchical menu structure which, when the message is presented to the recipient (106) by a messaging system (104), offers the recipient different navigational choices from which the recipient may select and thus effect the information content of what is presented. The structured message is sent by the sender to the recipient at an address on a messaging system that stores the message and is capable of interpreting and assembling the messaging elements in accordance with the embedded instruction and playing-out the message to the recipient when the recipient accesses the system and retrieves the message from storage. The structured message may also include links to a specific destination, to which the messaging system establishes a connection if the link is selected by the recipient during play-out of the message. Further, the messaging system can gather information from the recipient during play-out and forward that information to a specified destination, which may respond with another structured message. In the described embodiment, a phone markup language is used to define the structure and the inherent embedded instructions associated with the structure of the message.

Abstract: A device for reducing sound emitted by the air intake of a internal combustion engine is provided. The device includes a dampening chamber formed of a one piece construction by rotational molding. Included as part of this mold are two tubular pipe-like sections designating both an inlet and an outlet whereby air is directed into the engine through the inlet and sound emitted by the engine is dampened as it enters the outlet of the silencer. The inlet and outlet are each formed within a pocket constructed in the mold that assists in creating the flow path for air as it moves throughout the chamber. The arrangement of the inlet and outlet in relation to one another assists in defining the sound reduction capability of the instant design and construction.

Title: Oiless rotary scroll air compressor antirotation lubrication mechanism
Inventor: JONES CHARLIE E
IPC: F04C18/02
Filed: 2000-11-17
Granted: 2004-07-06
Abstract: A lubrication apparatus for an anti-rotation assembly of an oiless rotary scroll compressor is disclosed. The scroll compressor includes a stationary scroll element and an orbiting scroll element which orbits about the stationary scroll element in a non-rotational fashion. At least one anti-rotation assembly is provided for preventing relative rotation between the orbiting and stationary scroll elements. The anti-rotation assembly, which includes a first rotational bearing component mounted on the interior of the housing, a second rotational bearing component mounted on the orbiting scroll element and an offset crank member interconnecting the first and second rotational bearing components, is lubricated via a lubrication channel. The lubrication channel extends from a lubrication port disposed on the exterior of the housing, through the first rotational bearing component, thereafter through a channel provided in the offset crank member, thus allowing the lubricating agent (e. g., grease) to reach the second rotational bearing component. The provided anti-rotation assembly can thus be periodically lubricated without significant contact between the lubricating agent and the gas being compressed (e. g., air or refrigerant). Accordingly, any possible contamination of the exiting compressed gas is significantly reduced.
