摘要:
A floor covering installation tool for lifting partitions, furniture or the like. The tool includes a mechanism for raising and lowering a bracket. The bracket includes a member for securing the bracket to the raising and lowering mechanism. One or more lifters adapted for raising and lowering furniture, partitions or the like are coupled with the bracket. One or more elongated elements are coupled with the raising and lowering mechanism. The elongated elements may include a wedging mechanism to enable the moving of the elongated elements underneath furniture, partitions or the like.

A direct contact segmented column heater is described. The heater is capable of a broad heating and cooling range, and exhibits a very rapid response, with heating and cooling rates better than 350° C. min−1. In one configuration one or more of the individual heating devices are provided with full independent control and temperature feedback, and developed to provide excellent thermal stability at all temperatures. The heating devices or in other words active thermal transfer devices are capable of bi-directional operation, selectively heating (i.e., providing heat to) or cooling (i.e., withdrawing heat from) a column and/or contents of a column.
摘要:
A game feeder can include a housing having a cavity, an input aperture, and an output aperture; a base attached to the housing; a spreader below the output aperture; and a motor, attached to the feeder and the spreader, and configured to rotate the spreader. A feeder can include a varmint guard disposed below the output aperture, such that the spreader is between the guard and housing, to minimize interference and/or damage to the spreader or feeder by a varmint. A base can be provided as a single piece or base components configured to securely connect together to form the base.
摘要:
The invention relates to a modular humeral prosthesis for an inverse shoulder prosthesis, comprising an anatomical shaft (1) and a separable epiphyseal head (2) which may be angularly orientated by rotation about the longitudinal axis (XX) of the anatomical shaft. The anatomical shaft and the epiphyseal head comprise complementary angular indexing means (11, 28) for relative rotational fixation.
摘要:
A humeral component of a reverse shoulder prosthesis includes a stem part configured for location within the intramedullary cavity of the humerus, the stem part having a stem axis, an epiphyseal part connected to the elongate stem part and having a concave bearing surface defining an epiphyseal axis, and wherein the epiphyseal axis is offset posteriorly relative to the stem axis.
摘要:
An optical component of a projector is driven with a signal that contains one or more components that act to substantially cancel one or more unwanted oscillatory displacements of the optical component resulting from one or more unwanted oscillatory forces.

Method and arrangement for spray forming an article. The method includes spraying a plurality of metal streams upon a low-heat resistant model and thereby forming a spray formed article. Each of the plurality of metal streams is composed of moltenized droplets, and as between the plurality of metal streams, each is composed of different constituent elements. In the spray form process, conditions of the metal streams are controlled, particularly around the time that the droplets land, to prevent adverse affects such as melting or burning the master model. The spray conditions are controlled in such a manner that the individual metal droplets forming the metal streams remain substantially segregate. The segregated state is maintained through out solidification so that the resulting spray formed article is composed at least partially of psuedo-alloy.
摘要:
A scheduling system or method with an interface that can provide a queue-list view and a calendar view. In the scheduling of a particular job on a particular machine, characteristics relating to the particular job (“job characteristics”) and characteristics relating to the particular machine (“machine characteristics”) can be taken into consideration by the scheduling system.

Systems and methods for managing data in compliance with privacy, security and/or retention standards in business industries. A dynamic and customizable archival and retrieval system allows for information and documentation to be placed and made available in the system. The document type and identifying information for that document type are described. Definitions are established for the documents being managed, the data identifying the documents, and the retention policies for the documents. The documents are associated with the identifying data for a particular set of records. A single point of entry is provided for external and/or internal requests, and/or a single point of exit is provided for transmissions of information, wherein the transmissions to requestors include information that is individually approved. Moreover, digital authorizations and consents for retrieval from external data sources may be utilized.
摘要:
Systems and methods for producing three-dimensional objects are provided. One exemplary system, among others, includes a layer forming system. The layer forming system is operative to implement criteria for forming the three-dimensional object. The three-dimensional object includes a plurality of layers and each layer includes layers selected from a shell layer and an interior layer. The shell layer includes at least one shell voxel, and the interior layer includes at least one interior voxel. In addition, the layer forming system is operative to form the layers in an iterative manner according to the criteria, plane at least one layer in a manner according to the criteria, control waste produced by controlling the formation of the layers using the criteria provided, and form the object.
