  • Patent number: 7560778
    Abstract: An SOI integrated circuit includes ESD protection on an SOI chip. A first power domain and a second power domain are provided in the SOI chip. In one embodiment, a charge modulation network in the SOI chip between the first power domain and the second power domain mitigates accumulation of electrical charge in an electrically isolated region of the SOI chip. In another embodiment, an ESD protection device in the SOI chip electrically connects the first power domain and the second power domain via a low metal layer to provide a discharge path for accumulated charge.
    Type: Grant

  • Patent number: 5593141
    Abstract: A gate which hingedly fits closely between two spaced apart fence posts is provided. The gate has a hinge side member which extends directly adjacent a fence post. The hinge side member includes offset portions, each of which is displaced from the respective fence post by a gap. A hinge extends from the fence post across the gap of each offset portion to hingedly couple the gate to the fence post. The gate also has a latch side member which may be removably secured about another fence post. A sleeve having a gate latch coupled thereto is rotatably coupled about the latch member. The latch member has a slot extending therethrough and the sleeve has a notch extending therethrough. The sleeve may be rotated to a locking position on the latch side member where the notch is located over a portion at the slot. A rod extends inside of the latch side member. The rod has a cap end and a hooked end. The hooked end of the rod may be adjusted in the slot and notch by moving the cap end.

  • Patent number: 4758244
    Abstract: Densified coal pellets of improved physical properties and enhanced calorific value are produced by a process which includes subjecting coal to a shearing-attritioning step followed by extrusion and drying steps, characterised by incorporating an additive into the coal that is subject to the said shearing-attritioning step, said additive being chosen from one or more of the group consisting of: alkali metal hydroxides, alkaline earth metal hydroxides, ammonium hydroxide, alkali metal carbonates, alkaline earth carbonates, oxides of base metals, oxides of transition metals, and small molecule carbonyl compounds.

  • Patent number: 4701184
    Abstract: Process for treatment of brown coal which comprises subjecting the said coal to shearing forces to produce a plastic mass which is capable of conversion by subsequent compaction and drying into a fuel of increased density and enhanced calorific value, is characterized in that the water content of the coal is more than 54% and the shearing forces are applied for less than one hour, shorter times being preferred, for example less than 30 seconds. A preferred embodiment provides a continuous process in which the coal is treated in a machine that subjects it to sequential steps of shearing and extrusion in a continuous manner. The extruded product after drying provides the fuel of increased density and enhanced calorific value. The desired effect may also be obtained by treating part of a quantity of brown coal and blending the treated portion with the untreated remainder of the said quantity.
