Title: A comprehensive utilization method for preparing levulinic acid through directional liquefaction of lignocellulosic biomass
Inventor: JIANCHUN JIANG
IPC: C10G1/08
Filed: 2018-06-28
Granted: 2018-12-19
Abstract: The invention proposes a comprehensive utilization method for preparing levulinic acid through directional liquefaction of lignocellulosic biomass, in which the raw material, lignocellulosic biomass is preheated first to obtain holocellulose, and carbon-based solid acid catalyst is obtained by using solid residue; the holocellulose obtained are hydrolyzed through catalysis of the carbon-based solid acid catalyst in a sulfolane/water complex solvent system, and levulinic acid is prepared through directional liquefaction; after the liquefied system is filtrated, a small amount of solid residue is used to prepare the carbon-based solid acid catalyst, the filtrate is subject to fractional and reduced pressure distillation, and water, low-boiling-point liquid product and the target product, levulinic acid are gradually separated; the final residue, sulfolane and water obtained through fractional separation are recycled. The invention has advantages that the raw material can be obtained from a broad range of sources, the target product, levulinic acid in the sulfolane/water complex solvent system is highly selective, highly productive, and easy to separate, and the solvent and catalyst used can be effectively recycled and thus environment-friendly.

Title: Fluid propulsion system for accelerating and directionally controlling a fluid
Inventor: JESWINE WILLIAM W
IPC: B64C23/02
Filed: 1996-05-30
Abstract: The invention relates to a system for accelerating and directionally controlling a fluid by using a continuous dynamic surface, being applicable to conventional propulsion systems. According to the invention, the propulsion system for accelerating and directionally controlling a fluid has a continuous dynamic surface (40) for circulating through a fluid from an entrainment region (44) where the fluid is introduced to the dynamic surface (40) towards a thrust region (46) where the fluid is discharged from the dynamic surface (40). The dynamic surface (40) accelerates the fluid proximate to the surface so as to produce a layer of accelerated fluid from the entrainment region (44) through the thrust region (46). An engine is operatively connected to the dynamic surface (40) for driving the dynamic surface (40). A separator plate (60) is positioned next to the dynamic surface (40). The separator plate (60) is provided with a guiding edge (62) for separating the layer of accelerated fluid from the dynamic surface (40), and with a substantially flat thrust face (64) adjacent to the guiding edge (62) for directing the accelerated fluid in a desired direction. The separator plate (60) is positionable in such a manner with respect to the dynamic surface (40) that the edge (62) should be generally placed in the close proximity of the dynamic surface (40), while the thrust face (64) is substantially tangential to the dynamic surface (40) along at least a portion of the thrust region (46).

Title: Dynamic- elastic method and apparatus determining metal material hardness
Inventor: SAVU C ION
IPC: G01N3/52
Filed: 1998-04-02
Abstract: According to the invention, the dynamic-elastic method for determining the metal material hardness is a Shore-type method, wherein, the falling striking ball (8) crosses the light beam (12) of an optical barrier (E), triggering a counter which counts the impulses generated by an oscillator (Os) only for the period between the movement when the falling ball crosses the light beam and the moment when the rising ball crosses the same beam again. The number of counted impulses is inversely proportional to the hardness of the sample to be tested and indicates a time value which may be used together with a conventional hardness-timed period diagram to determine the hardness value. The striker (A) which is a component of the apparatus comprises the optical barrier (E) consisting of a LED (14) and a phototransistor (11).
