摘要:
A wrappable protective sleeve for preventing fluid from freezing in a conduit; method of protecting and heating a conduit, and method of constructing a sleeve for protecting and heating a conduit are provided. The sleeve includes an elongate wall having opposite edges extending lengthwise between opposite ends. The opposite edges are configured to overlap one another to form a dual layer overlap region including an outer portion and an inner portion underlying the outer portion to provide an enclosed tubular cavity. The at least one elongate heating element extends between the opposite ends within the inner portion of said wall.

In order to form a more stable silicon pillar which can be used for the formation of vertical transistors in DRAM cells, a multi-step masking process is used. In a preferred embodiment, an oxide layer and a nitride layer are used as masks to define trenches, pillars, and active areas in a substrate. Preferably, two substrate etch processes use the masks to form three levels of bulk silicon.

The method of the invention for manufacturing a correctable lens for glasses from an injectable thermo-plastic polymer material, or other moldable polymer, consists in: molding a glass blank (2) provided with the contour of the corrective lens; assembling the lens blank with a peripheral piece (3) having the same internal radius of curvature as that of the glass blank (2), so as to compose a lens blank (1); grinding and polishing the internal face of the lens blank (1) to obtain the desired ocular correction; separating the glass blank (2) from the lens blank to obtain the corrective lens ready for assembly with the frame.
摘要:
An electromagnetic protection sheath made of textile (10) is formed by conductive filaments extending in a first direction (X) and non-conductive filaments interlaced with the conductive filaments. Use in particular for shielding cables in aeronautical applications.
摘要:
A real-time trade resource management system is shown. In a construction site having one or more points of ingress/egress a tracking assembly at each point of ingress/egress is used to determine when workers are first and last observed on the site. Each worker on the site is assigned to a specific contract for the construction project. A server, computer readable medium, and method for managing trade resources is described.
摘要:
The present invention is a conveying apparatus for the bi-directional guidance of one or more objects, ingredients, products, containers, packs or packaging components from a primary location to a secondary location. Matter, such as the objects, ingredients, products, containers, packs or packaging component, supplied to the conveying apparatus from the primary location are monitored and corresponding speed and directional values are determined that are indicative of the relationship between matter supplied to the conveying apparatus and the matter being guided by the conveying apparatus to the secondary location. Based upon the speed and directional values, the conveying apparatus may be managed for bi-directional guidance of one or more objects from the primary location to the secondary location.
