Abstract: An infant care apparatus that has a canopy that can be moved vertically with respect to an infant platform on which the infant is positioned. The canopy contains a radiant heater that can be moved from a lower position enclosing the infant in an infant compartment to an upper position where the infant compartment is open and the radiant heater provides radiant energy to warm the infant.  When the canopy is in its lower position there is a convective heating system that provides a forced flow of heated air to the infant compartment to heat the infant.  The convective heating system includes a heater, a fan and various ducting and passageways in the infant platform that conduct the heated air to the infant compartment and receive air from that compartment for re-circulation. A  control system is used to operate both the convective heating system and the radiant heater and is operable to activate the radiant heater and disable the convective heating system when the canopy is in its upper position and, conversely, to activate the convective heating system and disable the radiant heater when the canopy is in its lower position. In the preferred embodiment, when the convective heating system is disabled, the control system has a separate control of the heater and the fan of the convective heating system and can inactivate the convective heating system by shutting off the fan while retaining the heater energized at a relative low setting of heat output, thus the heater can keep the various ducting and passageway surfaces warm and improve the warm up time that the convective heating system takes to warm up the infant compartment with heated forced air when the canopy is returned to is lower position and the convective heating system again activated.

Title: Method for treating vented or fugitive methane streams
Inventor: PEACHEY BRUCE RICHARD
IPC: B01D53/86
Filed: 2000-11-14
Abstract: A method of treating vented or fugitive methane streams, comprising the steps of providing two or more thermal catalytic converters coupled with pressure sensitive valves to form a catalytic converter assembly and at least one pilot heat source to initiate a catalytic reaction within one of the thermal catalytic converters. When a vented or fugitive methane stream is channelled through the catalytic converter assembly, the catalytic converters start up and shut down in sequence in response to variations in the supply of methane gas. Preferably, heat generated in initiated catalytic converters is used to sequentially initiate a catalytic reaction in remaining adjacent uninitiated catalytic converters.

Title: A rotatable breech mechanism
Inventor: ZEH MEINRAD
IPC: F41A15/12
Filed: 2000-12-15
Abstract: A rotatable breech mechanism includes a bolt rotatably supported in a chamber housing by a bolt handle, and which in one rotated position thereof is locked to a barrel chamber sleeve and in a further rotated position thereof is unlocked from the sleeve. A spring-loaded extractor is arranged at a front end of the bolt. The extractor, in one rotated position of the bolt, grips an edge of a bottom of a sleeve of a cartridge inserted into a cartridge chamber, whereby upon a rotation of the bolt from the one position into a further position the chamber housing with the bolt automatically carries out a movement away from the cartridge chamber during which the extractor releases the cartridge from the cartridge chamber. The chamber housing supports an axially movable pin which is supported at its front end on the barrel chamber sleeve. In one rotated position of the bolt, a rear end of the pin is received in a forwardly open recess of a shoulder surface on the bolt handle, and upon a rotation of the bolt out of the one position the rear end of the pin slides out of the recess onto the shoulder surface, and the chamber housing with the bolt is movable to a rearward position.

Abstract: An optical intensity control system for use with an optical switch providing individual signal paths between input and output ports. The system has a optical splatters connectable to output multiplexers of the switch and also has variable optical intensity controllers (VOICs) for insertion into the individual signal paths. The VOICs individually control the intensity of optical signals present in the signal paths in accordance with intensity control signals. An equalizer is connected to the splatters and to the VOICs, for producing an estimate of the optical power of each individual switched optical signal and generating the intensity control signals.      The equalizer is adapted to controllably isolate individual switched optical signals. In this way, individual and independent control of the power on each optical channel is provided, wavelength-dependent losses introduced by all the devices in the switch including the WDM devices at the output of the switch are accounted for and one optical coupler is required for each output optical fiber. Coarse equalization may be provided for each multiplexed optical signal either at the switch input or output, permitting a reduction in the dynamic range over which the VOICs inside the switch are required to operate.

Title: Content distribution method and content distribution system
Inventor: UCHIDA KAORU
IPC: G06F21/10
Filed: 2001-04-25
Abstract: A user terminal including a fingerprint sensor is connected via a network to a content distribution server. The server includes at least a fingerprint-feature comparing unit and a specified content distributor.      The fingerprint-feature comparing unit accesses a registered user information table in which personal information regarding a user, a user identification, and fingerprint feature information, and reads therefrom fingerprint feature information of a person who requests a content distribution so as to compare the fingerprint feature information with fingerprint feature information of the person inputted from the user terminal. The specific content distributor distributes a requested content to the user terminal only when match is made as a result of comparison.   The content can therefore be distributed via a network with higher reliability and safety.

Abstract: A generally transparent flexible packaging structure having an anti-transfer layer which, in a closed and sealed package, is at or close to an interior surface of the package. A contained food product in the package has a tendency to deposit a food product component on the interior surface of the packaging material and to thereby have a visually obscuring affect on transparency of the packaging structure. Anti-transfer material in the anti-transfer layer migrates to the interior surface of the package and interacts with the visually-obscuring component of the contained food product, thereby to attenuate or eliminate the visually obscuring effect of such component. Preferred primary polymer in the anti-transfer layer is EVA. Preferred anti-transfer materials include fatty acid esters and other amines and derivatives. The invention includes certain aspects of multiple layer packaging structures, closed and sealed packages, and methods of packaging food product.
