Polypropylene having high maleic anhydride content, between about 5 and about 45 g wt %, may be prepared by first reacting a metallocene-prepared polypropylene having terminal unsaturation with one mole equivalent of maleic anhydride to give polypropylene having a single unsaturation and a terminal succinic anhydride moiety. This product is then reacted with additional maleic anhydride in the presence of a free radical initiator (such as a peroxide or UV radiation) to give a polypropylene with maleic anhydride moieties along the backbone. The polypropylene product does not suffer scission or crosslinking with subsequently undesirable increases in molecular weight or viscosity. The maleic anhydride moieties provide reactivity to the polypropylene and thus expand its uses and applications.

A circularly shaped weight includes an opening in the center having a handle extending there through. The handle bi-sects the opening and creates equal openings for receiving a hand or foot of the user. The weight is particularly useful for individuals who may be incapacitated by arthritis or other physical ailments that may prevent them from properly grasping a weight. The novel shape is useful in stacking the weights when they are not in use. A plurality of circularly shaped weight may be fastened together via a coupler.

A method and system for selecting dental constructions using translucent materials that match an individual's preexisting tooth appearance uses a set of reference templates. The reference templates are constructed from layers of various translucent dental materials positioned on bases constructed from actual or simulated tooth structures. The layers of translucent materials have a thickness that varies in increments that correspond to the likely thicknesses of the materials when used in dental constructions. A reference table is created based upon color measurements of each of the reference templates. A color measurement of the individual's preexisting teeth is then compared to the reference table to determine which particular dental construction will most closely match the individuals preexisting teeth.

An elongated shaft has a shock-absorbing core, a fiber-reinforced durable plastic outer skin encasing the core, and an elongated stiffening member encased within the core. The elongated stiffening member may be a spar or a hollow tube. If it is a hollow tube, the tube may contain a weight that moves along the inside of the tube as the shaft is swung. The shaft also has a way to attach athletic equipment, such as a lacrosse head frame and net, to one end.

The invention relates to a permanent magnet direct current motor comprising: the inside of a shell of the motor is provided with a stator and a rotor, a stator core is provided with a winding coil, a rotor rotating shaft is provided with a magnetic core folded by discoid copper sheets. The periphery of the magnetic core is fixed with a rotor magnetic tile and the motor is provided with sensor magnetic steel and a position sensing element of a hall element. The sensor magnetic steel is arranged in a magnetic steel seat which is fixed on the motor rotating shaft extending out of an end cover and the sensor magnetic steel and the hall element are arranged in a cavity consisting of the end cover and a dust cover. As the magnetic steel seat is fixed on the motor rotating shaft extending out of the end cover, the permanent magnet DC motor is not interfered by the outside, so an electronic reversing signal of the motor is not interfered by the machining precision of the rotor and the armature current. The position sensing element is only influenced by the environment temperature, thereby leading the motor to work more stably.

The Chinese medicine is prepared with honeysuckle, skullcap root, schizonepeta herb, cape jasmine, forsythia and other nine kinds of Chinese medicinal materials. The Chinese medicine materials are extracted to obtain active components and further prepared into oral liquid, tablet, capsule, granule, dripping pill or other forms for fitting different patients.

The invention provides compositions featuring chitosan and polyethylene glycol and methods for using such compositions for the local delivery of biologically active agents to an open fracture, complex wound or other site of infection. Advantageously, the chitosan-PEG compositions can be loaded with one or more antimicrobial agents, including hydrophobic agents, and can be tailored to the needs of particular patients at the point of care (e.g., in a surgical suite, clinic, physician's office, or other clinical setting).

A Chinese medicine in the form of oral liquid for treating gastrointestinal disease is prepared from 16 Chinese-medicinal materials including uncaria stem with hooks, magnolia bark, trichosanthes root, tuckahoe, etc. Its preparing process is also disclosed.

The invention discloses a building template grinding device. The building template grinding device comprises a grinding box body, a building template, a material conveying mechanism, a grinding mechanism and a dust collector; material ports are formed in the portion, located at the same position, of the left and right side walls of the grinding box body, and support legs are fixed to the bottom ofthe grinding box body; the material conveying mechanism comprises two supports located at ends of the two material ports, a first driving shaft fixed between the two supports, driving wheels which are fixed to the two ends of the first driving shaft and are symmetric about the first driving shaft, two parallel driving belts which are used for conveying the building template to the other end of the grinding box body from one end of the grinding box body and a driving motor which provides power for the material conveying mechanism; clamping mechanisms used for clamping the building template arearranged on the opposite faces of the two driving belts at an equal interval in the respective length direction of the driving belts. The building template grinding device grinds the upper portions of the building templates simultaneously, the grinding efficiency is improved, the building template grinding device is suitable for grinding the building templates with different sizes, and the problem in the prior art that steel wire bundles need to be frequently replaced is also solved.

The invention discloses a remote control fishing boat applied to fish mainly. A fishhook is delivered to an exact fishing place through the remote control fishing boat, thus the fishing is easy and pleasant. The remote control fishing boat is mainly composed of an annular air sac, a circular waterproof cabin, a paying-off wheel, a screw propeller motor, a rudder, a propeller, a buoy, a fishhook, aline ring, a guide pulley, and a pulley supporting rod. The working principle is that the buoy is adjusted firstly, weight of a small lead weight is increased or reduced, thus the buoyancy force of the buoy is equal to the weight sum of the lead weight and the fishhook; a bait is hooked at the fishhook, a fishermen holds a remote controller to drive the fishing boat to a preset position, and remotely controls and orders the paying-off wheel to drop the fishhook to a predetermined depth, thus the fishermen can fish; when a fish bites the hook, the fishermen can start the button of the remote controller and instructs the paying-off wheel to wind up, lift up the fishhook and then drive the fishing boat to the shoreside; the fishermen can remotely control the paying-off wheel to unwind or wind up according to the discipline that different fishes swim in different water depths, thus the fishhook is placed at the water layer where the fish swims, and the fishery harvesting is increased.
