Abstract: Composite structures having a single continuous skin may be formed using automated fiber placement methods. These composite structures include frameless aircraft fuselage components offering an increased interior cabin width over conventional fuselage components. The composite structures may be constructed of multiple layers of fibers and other materials placed on a fiber placement tool that includes a mandrel body (40) surrounded by a bladder or an integral bladder/caul sheet having expansion spaces created within the caul sheet section. Uncured composite structures may be created by placing fibers around the fiber placement tool in a plurality of discontinuous segments that are capable of moving or sliding in relation to each other so that the uncured composite structure is expandable from within. Fluid openings may be provided in the outer surface of the mandrel body (40) for the application of vacuum and/or fluid pressure to secure the bladder to the mandrel body and to assist in the removal of the bladder from the mandrel body, respectively. Uncured composite structures may be sealed between the bladder and clam shell molds (30, 32). The uncured structures may be expanded against the inner surface of the molds by creating a vacuum between the bladder and molds.

Abstract: A method for predicting emissions from an emissions source. Test values of process variables relating to operation of the emissions source are gathered, along with corresponding time-correlated test values of the emissions variable to be predicted. Using the test values of the process variables, test values of a plurality of first coefficients are calculated for each process variable and associated with the process variable, and test values of a plurality of second coefficients are calculated for each value of each process variable and associated with the value of the process variable. Comparison values of the process variables relating to operation of the emissions source are gathered, along with corresponding time-correlated comparison values of the emissions variable to be predicted. Using the comparison values of the process variables, comparison values of a plurality of first coefficients are calculated for each process variable and associated with the process variable, and comparison values of a plurality of second coefficients are calculated for each value of each process variable and associated with the value of the process variable. Predetermined combinations of the comparison values of the variables and their associated coefficients are then iteratively compared with the test values of the respective variables and associated coefficients. Where the comparison yields matches between the comparison values and test values of the variables and their associated coefficients, the test values of the emissions variable associated with the matched test values of the variables are averaged and assigned as a predicted value of the emissions variable.

In the pitch-containing refractory raw material (1), the pitch particles are hardly aggregated to get hard even when the material (1) is stored for a prolonged period of time.  Therefore, the material (1) can be used in the form of microparticles on every occasions. When the material (1) is used as a part of the raw materials in the manufacture of a carbon-containing refractory, the pitch can be dispersed uniformly in the form of microparticles during mixing or kneading. The finished carbon-containing refractory shows a significantly high corrosion resistance. The refractory can be also prevented from increasing in Young~s modulus while retaining a satisfactory strength level, and can show an extremely excellent thermal spolling resistance even when the carbon content is low.

Patent CA-2627088-A1 (CA)
Inventor: MOLANDER MATS
IPC: H04L27/26
Filed: 2006-11-14
Abstract: A multi-carrier transmitter and transmission technique are described for transmitting payload data during a transmission time interval with reduced peak- to-average power ratio (PAPR). A multi-carrier modulator modulates subcarrier frequencies with payload data and provides a modulated signal for transmission during the transmission time interval. Excessive peaks in the modulated signal are extracted. The extracted peaks signal is transformed into the frequency domain to generate a peaks frequency spectrum which is processed using the frequency spectrum of certain subcarriers selected for reducing PAPR  to produce a peak compensation spectrum. In one approach, that spectrum is transformed into the time domain before being modified by the modulated signal in the time domain to reduce PAPR. Alternatively, that peak compensation spectrum is modified using a modulated frequency spectrum provided by the modulator in the frequency domain and the result is then transformed into the time domain to produce a modified modulated signal with reduced PAPR.
