Abstract:
A concealed door hingedly-affixed to a concealed door frame adapted to resemble shelving and cabinets, the concealed door assembly simulated permanently-affixed shelving and cabinets, and comprising a playless hinge and various overlapping, double-stacked and interconnected components.
Abstract:
A hinge assembly suppressing periodic motions and abrasive wear that supports an axial load and integrated a releasable hinge pin with retractable latch pins. The connector arms for the hinge assembly may include bearings, smooth outer surfaces, and tight fittings to help suppress the periodic motions and abrasive wear. Adjustable mounting apertures reduce stress on the hinge system. A hinge aperture for each member enables an axial load arm, such as thrust bearings, to pass through for reducing periodic movements during pivotal operation. A lock arm can also pass through the hinge apertures. The lock arm uses a locking pin to fasten the members together. A smooth outer surface inhibits abrasive wear and creates a smooth pivoting motion. Non-circular mounting apertures may enable adjustable mounting for reducing stress on the system.
Abstract:
A system and method, comprising: an interface port to a data communication network; a processor and associated memory, configured to execute a content browser, and a browser plugin, the browser plugin filtering at least a portion of data received by the content browser, and at least one of selectively blocking, modifying, or permitting interaction of a user with the received data, in dependence on at least a user-associated configuration file received from a remote resource through the interface port, and communicating at least one item of information which is blocked from access by the user; and a display port, configured to output information defining a user presentation of browser output. Communications between the remote resource and the plugin or browser may be encrypted. For example, the plugin receives user login information from the remote resource, and automatically fills in a login page for an Internet resource, while preventing user-access to the login information itself.
Abstract:
The invention is directed to synthesizing a phosphate-based electrode active material. The method includes the step of reacting two or more starting materials collectively containing at least a PO33− anion, an alkali metal and a metal which is redox active in the final reaction product, at a temperature and for a time sufficient to form the phosphate-based electrode active material.
Abstract:
The present invention provides a convenient process for making lithium sulfide involving heating one or more lithium-containing compounds and sulphur, wherein the heating step is performed at a temperature of 600 to 1500° C.
Abstract:
Methods for producing an electrode active material precursor, comprising; a) producing a mixture comprising particles of lithium hydrogen phosphate, having a first average particle size, and a metal hydroxide, having a second average particle size; and b) grinding said mixture in a jet mill for a period of time suitable to produce a generally homogeneous mixture of particles having a third average size smaller than said first average size. The precursor may be used as a starting material for making electrode active materials for use in a battery, comprising lithium, a transition metal, and phosphate or a similar anion.
Abstract:
Active materials for rechargeable batteries have a general formula Aa(MO)bM′cXO4 where A represents an alkali metal or mixture of alkali metals, a is greater than about 0.1 and less than or equal to about 2; MO is an ion containing a transition metal M not in its highest oxidation state, M′ represents a metal, or mixture of metals, and b is greater than 0 and less than or equal to about 1, c is less than 1 wherein a, b and c are selected so as to maintain the electroneutrality of the compound, and X is phosphorus, arsenic, or sulfur, or mixtures thereof. Preferred active materials are alkali metal vanadyl metal phosphates of general formula Aa(VO)bM′cPO4 where a and b are both greater than 0 and c may be zero or greater. New synthetic routes are provided to alkali metal mixed metal phosphates where at least one of the starting materials is a metal-oxo group (MO)3+, where M represents a metal in a +5 oxidation state. Reductive methods are provided for reacting a metal-oxo phosphate with an alkali metal compound in the presence of reducing carbon. The carbothermal reduction step can for example result in the reduction of a +5 metal to a +4 state or lower.
