摘要:
Methods for creating build sequences which are determined using computational chemistry algorithms to simulate mechanosynthetic reactions, and which may use the mechanosynthesis process conditions or equipment limitations in these simulations, and which facilitate determining a set of mechanosynthetic reactions that will build an atomically-precise workpiece with a desired degree of reliability. Included are methods for error correction of pathological reactions or avoidance of pathological reactions. Libraries of reactions may be used to reduce simulation requirements.

A rock crushing assembly is provided in the form of a pulverizing tumbler. The apparatus includes a faceted tumbler having a plurality of faceted end walls, a pair of parallel sidewalls, and an open interior. A power source and a drivetrain assembly attach to the sidewalls of the tumbler and rotate the same. Within the tumbler is adapted to be placed rocks and minerals to be pulverized, wherein pulverizing media is placed in the tumbler with the rocks to break down the rocks into fine, granular material. One of the end walls of the tumbler is removable to allow access to the tumbler interior. One or more gaps or apertures through one or more of the end walls allow the pulverized material to exit the tumbler during operation, thereby reducing build-up of loose material that can dampen impacts within the tumbler.

A battery lift jack assembly for lifting batteries comprising: a platform for placement of a battery, where the platform is suspended on a platform pedestal, where the pedestal moves vertically to raise the platform to a desired height; a base that is provided on wheels, where the platform pedestal is secured on the base; a jack assembly for moving the platform pedestal vertically; and a connector, where the connector joins the platform pedestal to the jack assembly and moves vertically along the jack column. The jack assembly includes a jack handle and jack column. The platform may further include lips, which help to secure the battery in a stationary position while the platform, is moved vertically.

Injection molding method and apparatus for ejecting a molded plastic article from a mold. A lifting structure and/or step is provided with a lifting portion which is configured to contact substantially one half of an end of the molded plastic article along a line substantially perpendicular to the lifting direction. Since the molded plastic article is lifted by its end, the article does not have to be solidified at its interior, thus allowing earlier removal of the article from the mold, reducing cycle time. A tapered surface forms an acute angle with respect to the lifting portion to form a tight seal with the mold, preventing leakage. Preferably, the neck ring engages only an outer circumferential portion of the molded plastic article during a majority of a mold opening stroke.

The present invention provides a stable, relatively low concentration of an aqueous fabric softening composition having a viscosity of from about 30 cps to about 2000 cps. The composition has a pH such that it is microbial stable and of commercially acceptable viscosity. This invention is predicated on the discovery that the use of weak acids such as lactic or citric to reduce the pH of the composition not only gives appropriate microbial efficacy but does not adversely affect the use of viscosity enhancing agents and the viscosity of the finished product is easily controlled.

A handrail and bracket assembly includes a pair of brackets having two off-set channels that permit the hand rail to be positioned in an expanded or in-use position or a collapsed or stowed position. At least one mounting opening is provided in each bracket for securing it to a wall or other surface. The channels and openings are positioned such that the brackets can be attached to the handrail prior to attaching the brackets to a wall or other surface.

A method, apparatus, and article of manufacture is disclosed for providing a dental treatment plans using electronic models, and more particularly to a method, apparatus, and article of manufacture for utilizing electronic models of patient teeth in interdisciplinary dental treatment plans. The system and method permit the electronic generation and specification of electronic models and then dental treatment plans for patients that require interdisciplinary treatment that may include orthodontic treatment, may include the generation of crown, bridge, and implant dental appliances that may be specified in an industry standard file specification. This specification is utilized in a rapid prototyping process to generate a wax impression for the appliance that may then be fabricated using standard lost-wax fabrication techniques.

A method, apparatus, and article of manufacture provide a distributed computing system delivering and manipulating electronic model images to end users. One aspect of the present invention includes a method for providing electronic delivery of electronic model images. The method generates one or more electronic model images, a portion of the electronic model images being generated from scanned electronic data of a physical object, stores the electronic model images within computer readable memory of a server-based computing system, delivers the electronic model images to a remote client computer over a distributed communications network, manipulates the electronic model images upon the remote client computer, and performs analysis and a course of action using the manipulated electronic model images. The electronic model images comprise in part a polygonal mesh representation of the physical object.
