摘要： The invention provide a new class of silicone-containing prepolymers containing poly(oxyalkylene) blocks, polysiloxane blocks, and actinically-crosslinkable groups which are acryl groups, thiol groups, ene-containing groups or combinations thereof. A preopolymr of the invention is prepared in a one-pot procedure according to the Micahel addition of thiol to electron deficient alkenes, such as α,β-unsaturated carbonyl compounds, without need for additional reaction step(s) to introduce actinically crosslinkable groups. The present invention is also related to silicone hydrogel contact lenses made from this class of silicone-containing prepolymers and to methods for making the silicone hydrogel contact lenses.

摘要： This Invention relates to methods of treating a subterranean hydrocarbons reservoir comprising contacting the formation with a treating fluid comprising an aqueous solution, an acid, a surfactant acting as gelling agent essentially consisting of erucylamidopropyl betaine (or a protonated/deprotonated homolog or salt thereof). The treating fluid may further comprise a lower n-alcohol for improved temperature stability.

摘要： A method is provided for diverting the majority of the fluid injected into a stratified subterranean formation, that has at least one problematic zone and at least one hydrocarbon zone, into the hydrocarbon zone. In the method, a viscous diverting fluid made with a gelling amount of a surfactant and an acid is injected before the main treatment; after the treatment the acid decomposes the surfactant. The main treatment may be hydraulic fracturing, acid fracturing and matrix acidizing. The fluid used as the diverting fluid may also be used as the carrier fluid in hydraulic fracturing or gravel packing. Destruction of the surfactant alleviates the potential of diverters or carrier fluids to damage formations.

摘要： This invention is related to a dual-functional medium shredding machine structure, specifically designed for shredding or destroying paper printed with data to be destroyed, optical discs containing data to be destroyed, or expired credit cards. This invention mainly implements a pair of shredding roller blades with sharp teeth as shredding means, and is characterized by providing separate feeding inports, including a paper inport for feeding paper in an inclined orientation, and a disc inport for feeding discs in a vertical orientation, wherein the inports are each led to the same shredding roller blades such that, regardless of the type of substance being fed by the user, the paper or the discs can both be shredded by the shredding roller blades, and the shredded scraps are dispensed to separate collectors through an identical exit by means of an auto-revolving switch plate; and a touch switch at each of the inports such that, while feeding the paper or the discs, the touch switch activates the shredding roller blades to perform shredding task, and drives the switch plate so as to dispense shredded scraps of different substance into different collectors.

摘要： This invention is related to a gear protection device of a paper shredder. The gearbox of the paper shredder is provided with a transmission component having a safety trip and with an adjustable transmission load. The device is provided on an end face of a primary gear driven by an output shaft of a motor, which end face is provided with a radial teethed face that couples to an end face of a secondary gear being provided with another radial teethed face. The primary and second gears are serially connected on a central shaft. Another end of the secondary gear is formed with a male gear engaging and being driven by another gear mechanism. Another end of the primary gear is provided with an adjustable transmission load structure that comprises a compression spring, a bearing, and a screw for adjusting to an appropriate force between the primary and second gears, whereby when the transmission load being subjected to the secondary gear is greater than such a force, retreating of the spring after compression causes the primary and secondary gears to trip away from each other such that the friction only extends to the radial awl teethed faces so as to effectively protect the motor as well as other gearboxes.
摘要翻译：本发明涉及一种碎纸机的齿轮保护装置。碎纸机的齿轮箱设置有具有安全跳闸并且具有可调节的传动载荷的传动部件。该装置设置在由电动机的输出轴驱动的主齿轮的端面上，该端面设置有与设置有另一个径向开口面的副齿轮的端面相连的径向开口面。主齿轮和第二齿轮在中心轴上串联连接。副齿轮的另一端形成有接合并由另一齿轮机构驱动的公齿轮。主齿轮的另一端设置有可调节的传动装载结构，其包括压缩弹簧，轴承和用于调节到主齿轮和第二齿轮之间的适当力的螺钉，由此当传动载荷受到副齿轮大于这样的力，压缩后的弹簧的后退会导致主齿轮和副齿轮彼此脱离，使得摩擦力仅延伸到径向锥形表面，以有效地保护马达以及其它齿轮箱。
