Title: Compost heat recovery system and method
Inventor: ALLAIN CONRAD
IPC: C05F9/04
Filed: 2007-07-27
Granted: 2008-08-19
Abstract: In a composting system for outdoor operation for large-scale composting of municipal and other wastes, one or more large compost piles or windrows a re supported on a pad, and covered with a removable cover. Fluid circulation pipes are embedded within the pad, to recover heat generated by aerobic decomposition of the organic matter and to then transfer the recovered heat to a region of the pad underlying an edge region of the cover. The recovered he at warms up the edge region, to thaw snow and ice which may have built up on the cover at the edge region, thereby permitting the user to easily remove t he cover without damage. A computerized controller operates the system, including circulation of fluid from selected central zones to selected edge zones, with real time data collection of temperature at critical locations and optional serial extraction and application of heat from and to multiple regions on th e pad.

Granted: 2010-09-21
Abstract: There is disclosed a method of manufacturing a ceramic porous membrane in which a uniform porous membrane having less coarse and large pores and less defects and having a small membrane thickness can be obtained with less membrane formation times. There is disclosed a method of manufacturing a ceramic porous membrane in which a ceramic porous membrane is formed on inner wall surfaces of through holes of a cylindrical or lotus root-like porous base member. A porous base member 1 is installed so as to arrange the through holes of the base member in a vertical direction, a ceramic sol liquid 5 having a temperature difference of 50°C or less between the ceramic sol liquid and the porous base member 1 is supplied to the inner wall surface of the porous base member 1, the liquid supply is stopped at a stage where the ceramic sol liquid 5 is in excess of an upper end portion of the porous base member 1, and the ceramic sol liquid 5 is extracted from the downside of the porous base member 1. Subsequently, after the ceramic sol liquid 5 is completely extracted, a pressure difference is created so that a pressure on the side of an outer peripheral surface of the porous base member 1 is lower than that on the side of the inner wall surface of the porous base member 1.

Title: Solid phosphoric acid catalyst and methods of olefin dimerization reaction with the same
Inventor: HAMAMATSU TATSUO
IPC: C07C2/18
Filed: 2006-05-25
Granted: 2012-05-08
Abstract: A solid phosphoric acid catalyst which has high activity and attains high dimer selectivity in olefin dimerization reactions; and efficient methods of olefin dimerization reaction. The solid phosphoric acid catalyst comprises a carrier and phosphoric acid supported thereon. When the solid phosphoric acid catalyst is heated at 250°C for 20 minutes, heating loss of water is 50 mass% or more based on diphosphorus pentaoxide (P2O5) derived from the phosphoric acid. One of the methods of olefin dimerization reaction comprises bringing an olefin-containing feed material containing water in an amount of 10-1000 mass ppm into contact with the catalyst to initiate the reaction.  Another method of olefin dimerization reaction comprises succesively conducting the following steps: a step (1) in which a hydrocarbon containing water in an amount of 10-1000 mass ppm and containing substantially no olefin is brought into contact with the above mentioned catalyst; a step (2) in which the pressure and temperature are regulated to conditions suitable for the initiation of olefin dimerization reaction; and a step (3) in which the hydrocarbon is displaced with an olefin-containing feed material containing water in an amount of 10-1000 mass ppm to bring the olefin into contact with the solid phosphoric acid catalyst and thereby to initiate the reaction. Still another method is the olefin dimerization reaction method described above wherein the temperature in the reaction initiation conditions is higher by 5-50°C than the reaction temperature in olefin dimerization in a stationary state after the step(3).

Abstract: A method and hearing aid for processing sound signals for hearing impaired persons by providing multi-band compression processing is described. An input sound signal is filtered into a number of frequency bands to obtain band split signals. A signal level for each of the band split signals is determined and the frequency bands are arranged into a number of groups. Based on the signal levels in each of the groups, a compressor input level for a number of band split compressors each associated to one of the frequency bands is calculated.  A compressor gain for each band split compressor is determined based on the corresponding compressor input signal and the band split signals are amplified with the corresponding compressor gain to produce an output sound signal.

The change in value of the intensive properties allows for economies in shipping, where a higher density product is shipped to the consumer. At the point of use, the consumer activates the product to achieve the increase surface area and lower density. The increase in surface area and concomitant decrease in density provides for increased efficacy in cleaning. The plastically activatable state may be provided by a series of slits 44 or other lines of weakness in the tissue. The tissue may comprise cellulosic and/or synthetic fibers.
