    摘要： A new fundamental structure that is simply and inexpensively formed offers a wide variety of functional attributes. The structure is formed from thin film sheet stock by pressure induced formation of select arrays of depressions and raised portions. The patterns formed provide an approximate minimal surface. Composite structures created by selective arrangement of the deformed sheets provide a highly functional arrangement of passageways and support lattice. These structures have low density, high strength, and select fluid carrying and heat exchange capabilities.

    摘要： A new solar heat engine is provided in the form of a pressure oscillation generation device having a chamber with two spaced apart walls, means on one wall receiving sunlight through said one wall, means on the other of said walls continuously cooling said other wall, a light absorbing surface on a thermal shield movable between said walls, means for automatically alternating said sunlight absorbing surfaced thermal shield back and forth between said walls whereby a heat expansible fluid contained in said chamber is alternately heated and cooled thereby causing said fluid to undergo alternate expansions and contractions. The alternate expansions and contractions of the fluid are used to produce useful work by pump action, torque action, compression and the like.

    摘要： Calcium phosphates useful as bone substitute material or for the manufacture of prosthetic devices have been prepared from calcium hydroxyapatite material which has a uniformly permeable microporous structure characterized by a substantially uniform pore volume in the range from about 10 to about 90% and by a pronounced three-dimensional fenestrate structure corresponding to the microstructure of the porous carbonate echinoderm or scleractinian coral skeletal material of marine life by reacting said calcium hydroxyapatite material which has a calcium to phosphorus atomic ratio of about 1.66 with a phosphate-contributing or phosphorus-contributing moiety or with a calcium-contributing or calcium oxide-contributing moiety so as to alter the calcium to phosphorus Ca/P atomic ratio to yield a calcium phosphate material retaining the above-described microstructure of the porous carbonate echinoderm or scleractinian coral skeletal material but having a calcium to phosphorus Ca/P atomic ratio less than or greater than 1.6, such as a calcium phosphate material comprising dicalcium phosphate and/or tricalcium phosphate and having a calcium to phosphorus Ca/P atomic ratio in the range 1.0-1.5 when the calcium hydroxyapatite material is reacted with said phosphate-contributing or phosphorus-contributing moiety or a calcium phosphate material having a calcium to phosphorus Ca/P atomic ratio greater than 1.66 up to 2.0 when the calcium hydroxyapatite material is reacted with said calcium-contributing or calcium oxide-contributing moiety and comprising tetracalcium phosphate.

    摘要： This invention comprises an apparatus and process for drying and/or heating materials. This invention was designed for use in the production of charcoal from wood feed material; however, it can be used to heat and/or dry many types of materials. Feed material is disposed in a reactor, wherein there is provided a first array of input channels extending through said feed material, through which hot gases are introduced into said feed material, and a second array of output channels extending through said feed material to collect and exit those hot gases and any gases or vapors derived from the heating and/or drying of the feed material.
