Abstract: A method of producing a titanium alloy composite material comprises mixing carbon fibers and a powder of an element which forms a carbide in reaction with carbon, subliming the element under high temperature vacuum, and coating the carbon fibers with a layer containing the element and the carbide to produce coated carbon fibers. The method further comprises mixing the coated carbon fibers and titanium alloy powder to form a mixture, and applying a mechanical impact force to the mixture to fix the carbon fibers on the surface of the titanium alloy powder to obtain a carbon fiber-fixed titanium alloy powder. The method further comprises sintering the carbon fiber-fixed titanium alloy powder to form a sintered body and plastic working the sintered body to disperse the carbon fibers in crystal grains of the titanium alloy.
Abstract: A gray scale bistable electro-optic display is driven by storing a look-up table containing data representing the impulses necessary for transitions, storing data representing at least an initial state of each pixel of the display, storing data representing temporal and gray level prior states of each pixel, receiving an input signal representing a desired final state of at least one pixel of the display; and generating an output signal representing the impulse necessary for a transition, as determined from the look-up table, dependent upon the temporal and gray level prior states. Other similar methods for driving such displays are also disclosed.

Abstract: A method and device for vaporizing a liquid reactant. A vaporizing plate having a top surface defines a liquid flow channel, the channel being laterally delimited by edges having a height greater than a minimum thickness of liquid reactant required to generate vapor under film or nucleate boiling regime. A heating system is associated to the vaporizing plate for heating the liquid reactant over a minimum temperature required to generate vapor under nucleate or, preferably, film boiling regime. A cap covers the vaporizing plate to collect the vapor at a predetermined pressure and provided with a vapor exit and a liquid feeder feeds the liquid reactant onto the vaporizing plate.

Abstract: Leather sheet material is made by hydroentangling a web (4) of mixed reclaimed leather fibers and synthetic fibers. The synthetic fibers are meltable bicomponent fibers which are heated prior to entanglement to fuse and form a supporting network for the leather fibers. A sheet of tissue paper (1a) is laid over the surface of the leather fiber web (4) and hydroentanglement jets (16) are directed through the tissue paper into the web.
Abstract: A process is provided for producing glycolic acid from formaldehyde and hydrogen cyanide. More specifically, heat-treated formaldehyde and hydrogen cyanide are reacted to produce glycolonitrile having low concentrations of impurities. The glycolonitrile is subsequently converted to an aqueous solution of ammonium glycolate using an enzyme catalyst having nitrilase activity derived from Acidovorax facilis 72W (ATCC 57746). Glycolic acid is recovered in the form of the acid or salt from the aqueous ammonium glycolate solution using a variety of methods described herein.

Abstract: A bistable electro-optic display has a plurality of pixels, each of which is capable of displaying at least three gray levels. The display is driven by a method comprising: storing a look-up table containing data representing the impulses necessary to convert an initial gray level to a final gray level; storing data representing at least an initial state of each pixel of the display; receiving an input signal representing a desired final state of at least one pixel of the display; and generating an output signal representing the impulse necessary to convert the initial state of said one pixel to the desired final state thereof, as determined from said look-up table. The invention also provides a method for reducing the remnant voltage of an electro-optic display.

Abstract: A front plane laminate (see U.S. Pat. No. 6,982,178) is produced by forming a sub-assembly comprising a lamination adhesive layer and an electro-optic layer, forming an aperture through the sub-assembly, and securing a light-transmissive electrode layer to the sub-assembly so that the electrode layer extends across the aperture. Alternatively, formation of the aperture is omitted, and the electrode layer has a tab portion extending beyond the edges of the lamination adhesive and electro-optic layers. When a front plane laminate is secured to a backplane to form an electro-optic display, a stiffening layer may be attached to either part to increase its stiffness, then removed after the lamination. An electro-optic display or front plane laminate may use an adhesive layer comprising separate layers of cross-linked and non-cross-linked adhesive.

Abstract: The method and device of this invention immobilizes a person in a secure, upright restraint system in a police vehicle. It can be easily and safely applied by public safety officers including police or other law enforcement personnel and medical personnel to secure a person against undesired movement while maintaining them in an upright, sitting position which leaves the diaphragm free for natural, unrestrained breathing movement. The asphyxia-preventing restraining device comprises an ALR/ELR retractor. The ALR/ELR retractor comprises a shoulder harness having a pair of seat belt buckles, which significantly reduces the possibilities of injuries to police officers.

Abstract: A method of manufacturing a cementitious composite including: (1) mixing an extrudable cementitious composition by first forming a fibrous mixture comprising fibers, water and a rheology modifying agent and then adding hydraulic cement; (2) extruding the extrudable cementitious composition into a green extrudate, wherein the green extrudate is characterized by being form-stable and retaining substantially a predefined cross-sectional shape; (3) removing a portion of the water by evaporation to reduce density and increase porosity; and (4) heating the green extrudate at a temperature from greater than 65° C. to less than 99° C. is disclosed. Such a process yields a cementitious composite that is suitable for use as a wood substitute. Particularly, by using higher curing temperatures for preparing the cementitious building products, the building products have a lower bulk density and a higher flexural strength as compared to conventional products.
