Title: High-temperature gas generating apparatus
Inventor: IKEBE HIROSHIGE
IPC: F28F19/04
Filed: 1995-08-10
Abstract: A high-temperature gas generator capable of supplying an impurities-free hightemperature gas of around 700-1400 ~C for a long period of time with minimum temperature variations, after a short preparing time. This gas generator includes heat accumulators (4, 5, 15, 16) capable of transmitting the sensible heat of a combustion gas to combustion air with a high efficiency by switching at a short cycle, and burners (2, 3) for burning with mainly a gas fuel supplied thereto, and forms a combustion apparatus adapted to supply combustion air or an arbitrary gas, which is to be heated to a high temperature, through the heat accumulators (4, 5) and discharge the combustion gas, to accumulate the heat in the heat accumulators (4, 5). After the temperature of the heat accumulators (4, 5) reaches a predetermined level, the combustion operation is interrupted, and the air or an arbitrary gas only is passed through the heat accumulators (4, 5), whereby an arbitrary gas heated to a predetermined level is supplied to the outside for a predetermined period of time.

Title: Child resistant bottle closure
Inventor: THOMAS JOHN HALL
IPC: B65D50/08
Filed: 1995-05-03
Abstract: A package (10) suitable for storing and dispensing potentially dangerous material, which is resistant to opening by childern yet readily openable by adults. The package is preferably a bottle (14) which has a body and a finish portion (24). The finish portion (24) has a threaded outer (28) end for mating with a closure (12). A resiliently deformable cantilevered beam (32) is connected to the finish portion (24) between the threaded outer end (28) and the body of the bottle (26). The beam (32) is angled outward and downward from the finish portion (24). The beam (32) has a substantiallly vertical locking surface (36) and a pushtab (34) spaced along the beam (32). The angle of the beam (32) is such that the pushtab (34) may be depressed substantially radially toward the finish portion (24). The locking surface (36) is located between the finish portion (24) and the pushtab (34) so that depression of the pushtab (34) results in a greater beam deflection and lower deflection force at the pushtab (34) than at the locking surface (36). A bottle closure (12) has threads for rotatably securing the closure (12) to the finish portion (24) of the bottle. The closure (12) also has a tooth projecting (22) radially inward from its lower inner surface and so shaped and positioned that it will engage the locking surface (36) of the resilient beam (32) whenever there is an attempt to unscrew the closure. It thereby prevents removal of the closure (12) until the pushtab (34) is manually depressed to disengage the closure tooth (22) from the locking surface (36) of the cantilevered beam (32).

Title: An fft-based multitone dpsk modem
Inventor: JAISINGH GOPAL K
IPC: H04L27/26
Filed: 1997-08-21
Abstract: A system and a method for transmitting coded information bits using multitone techniques on a frame-by-frame basis. For transmission, coded information bits are mapped into differential phase signals and absolute phase signals are generated based on differential phase signals. N complex symbols are then generated and inverse discrete Fourier transformed into N complex, time-domain samples, which are augmented with a cyclic prefix and suffix. The augmented N complex, time-domain samples are then separated into two real samples and converted into first and second baseband signals. The first and second baseband signals are impressed into quadrature carrier components to form in-phase and quadrature signal components which are combined into an RF signal prior to transmission. For reception, a received RF signal is non-coherently quadrature demodulated into first and second quadrature baseband signals. First and second quadrature sample sequences are generated by sampling the quadrature baseband signals in parallel. The added cyclic prefix and suffix are discarded, and N complex numbers are generated from the first and second quadrature (real) sample sequences. N channel-weighted tones are generated by performing a discrete Fourier transform on the N complex numbers. N phase difference signals are generated which are demapped into coded information bits according to a predetermined phase constellation.

Title: Method for characterization of the fine structure of protein binding sites
Inventor: WOODS VIRGIL L JR
IPC: G01N33/53
Filed: 1996-04-29
Abstract: The binding sites of binding proteins and their binding partners are characterized, at the individual amino acid level, by a combination of heavy hydrogen (tritium or deuterium) exchange labeling and sequential degradation (preferably, by carboxypeptidase) and analysis of labeled fragments under slowed exchange conditions. By first labeling the binding partner and labeling the binding site of the protein indirectly (by exchange at the binding surface), the binding site may be differentiated from allosterically protected segments of the binding protein.
