摘要:
A continuously variable composition copolymer is prepared in a reaction system, by (a) providing a reaction vessel comprising a first monomer composition; (b) providing a feed vessel comprising a second monomer composition; (c) initiating a polymerization reaction in the reaction vessel; (d) continuing the polymerization reaction during the gradual addition of the second monomer composition from the feed vessel to the reaction vessel, wherein the gradual addition of the second monomer composition is performed such that the continuously variable composition copolymer is obtained; (e) maintaining the polymerization until at least 90% of the total monomer composition has been converted to the copolymer; wherein the copolymer has a weight average molecular weight from 10,000 to 1,000,000; wherein the copolymer is soluble in lubricating oil, wherein the monomers of the first monomer composition provided in the reaction vessel comprise at least 50% by weight of all the monomers used to prepare the copolymer.

A fire extinguisher (10) has a discharge member (12) for directing an extinguishing agent from the extinguisher (10) towards a target. The extinguisher (10) also has at least one light beam director (17, 18) for directing a beam of light (19, 20) in a predetermined direction relative to the discharge member (12) so that the discharge member (12) can be aimed at a target by directing the light beam (19, 20) at or adjacent to the target.
摘要:
The invention provides methods for producing high resolution crystals of ribosomes and ribosomal subunits as well as crystals produced by such methods. The invention also provides high resolution structures of ribosomal subunits either alone or in combination with protein synthesis inhibitors. The invention provides methods for identifying ribosome-related ligands and methods for designing ligands with specific ribosome-binding properties as well as ligands that may act as protein synthesis inhibitors. Thus, the methods and compositions of the invention may be used to produce ligands that are designed to specifically kill or inhibit the growth of any target organism.

A method for providing a urinary tract tissue graft composition includes providing a tissue culture frame and a segment of small intestinal submucosa and positioning the segment of small intestinal submucosa in the tissue culture frame such that the segment of small intestinal submucosa is suspended and held in a taut position by the tissue culture frame. Smooth muscle and urothelial cells are isolated from a tissue specimen of a subject and cultured, and then seeded upon the segment of small intestinal submucosa, thereby forming a urinary tract tissue graft. A tissue culture frame in which such a urinary tract tissue graft may be formed is also disclosed.

A system for creating a coil of stamps from a web of stamp material having an adhesive applied to a side thereof is provided. The system includes an anvil and a perforation die cooperating therewith with the web passing therebetween in order to perforate the web. The web is passed between the anvil and the die with the adhesive side thereof facing the anvil. The anvil is chilled so as to inhibit the adhesive from adhering thereto as the web is perforated. The anvil may be chilled from an outer surface thereof, or may be hollow and chilled from an inner surface thereof. In the former case, the system preferably includes a trough holding a chilling material through which at least a portion of the outer surface of the anvil is passed. Where the anvil is chilled from an inner surface thereof, a cooling fluid is preferably passed therethrough.

An integrated and computer controlled printing press, inspection rewinder and die cutter system for manufacturing printed products from a web of material is provided, which generally comprises at least one rotary die cutter, a plurality of cameras, a plurality of networked computers electrically connected to the cameras for inspecting the print registers and the print to cut register of each product, and at least one monitor connected to the networked computers. The system uses an identification code for each product to precisely detect, track and record in a permanent format the defective and non-defective printed products at every stage of the manufacturing process and can also automatically adjust the die cutters to correct the cut to print registration in real time.
摘要:
A system of elements capable of transferring thermal energy from outside to inside a building or vice versa, has abutting waterproof trays (a) enclosing tubes (d) at their junction. Correspondingly long slotted profiles (b) enclosing the joints and held captive by them may be rotated to allow the insertion of rigid elements (c) sequentially so that adjacent pairs of profiles (b) are restrained from further rotational movement and provide a planar surface. Rigid elements (c) of sufficient density may provide a flat roof which is self-ballasting against wind uplift without penetrative fixings to the sub-surface.

A firearm suppressor with a monolithic core includes an elongate main body, a projectile borehole extending an entire length of the elongate main body such that the elongate main body includes both an entrance opening for the projectile borehole and an exit opening for the projectile borehole, and multiple hollow chambers. The entrance opening is structured to attach to an end portion of a barrel of a firearm. The hollow chambers are disposed along the length of the elongate main body and connect the projectile borehole to an outer surface of the elongate main body. A first one of the hollow chambers is disposed in a direction perpendicular relative to the projectile borehole, and a second one of the hollow chambers is disposed in a non-perpendicular direction relative to the projectile borehole.

A new and distinct cultivar of Buddleja plant named ‘Pink Pagoda’, characterized by its upright, outwardly spreading and mounding plant habit; continuous flowering habit; long narrowly conical inflorescences with numerous pink-colored flowers; and good garden performance.
摘要:
A new cultivar of Buddleja named ‘MORNING MIST’ that is characterized by hardiness, compact habit, intensely silver leaves, and white flowers. In combination these traits set ‘MORNING MIST’ apart from all other existing varieties of Buddleja known to the inventor.
