    摘要: Techniques for forming cast parts for medical devices suitable for contact with internal regions of patients are described herein. Such parts can be small in scale (e.g., having a major axis less than 0.3 inches, and/or a minor axis less than about 0.08 inches), and can be formed from metals that have a high melting point and high reactivity with environmental components or mold surfaces, such as stainless steel and titanium alloys. Such techniques can include injecting molten metal into the sprue of a mold tree such that the side runners are backfilled after the molten metal impacts a closed end of the sprue. Side runners can be oriented in particular directions and positions to promote backfilling. As well, flask temperatures and the use of surfactants can also promote cast part formation, hindering the formation of surface defects.

    摘要: There is disclosed an activated sewage disposal plant of the compact or so-called "packaged" type and a method of processing sewage wherein a fast filter is provided through which the effluent liquid from the primary processing is passed, provision being made for backwashing the fast-flow filter from time to time with the backwash being collected in a well or vessel from which it is recycled at a controlled rate to the raw sewage. The entire plant can be embodied in a compact package unit, one common type of which comprises two concentric tanks, the outer one of which is divided into several compartments.

    摘要: Structures and methods for hindering molded part deformation during densification are discussed. Such devices and techniques can help alleviate stresses that tend to result in part deformation during firing, sintering, or other densification processes, and thus reduce the need for secondary straightening operations post-densification. In some instances, a support structure is utilized to orient a molded greenbody in a preferred direction to reduce deformation during firing (e.g., orienting a thin tail section is a plane parallel to the direction of gravity). The support structure can also be part of, or the entirety of, a thermal mass to help alleviate stresses that lead to part deformation. Though such structures and methods can be used for any molded piece, it can be particularly used to create a portion, or an entirety of, a medical device such as a jaw of an surgical instrument.

    摘要: A nozzleless, strainerless filter bottom includes a first set of blocks laid end-to-end in spaced parallel rows to define elongated channels. Transverse grooves in the lower surface of the first set of blocks provide communication between adjacent channels. A second set of blocks laid end-to-end in spaced rows which are parallel to and overlap the rows of first blocks form covers for the longitudinal channels. Transverse slots in the lower surface of the second set of blocks form with the upper surface of the first set of blocks passages through which filtrate and backwash fluid may pass without clogging. A pair of laterally spaced longitudinal flanges depending from the lower surface of the second set of blocks extend into the lower elongated channels and bear against the adjacent sides of the first set of blocks to prevent lateral displacement of both sets of blocks. Longitudinal ribs extending upwardly from the upper surface of the first set of blocks give added strength thereto and prevent clogging of the passages with filter media.
