摘要:
An extraction device is provided for use when extracting a ceramic foam filter, as used for example in the production and processing of aluminium. The extraction device includes an anchor device (1) having an anchor body (2) suitable for driving into the filter, and a screw thread (8) that extends along at least part of the length of the anchor body, for engagement with the filter.

An electrical connector including a first connector portion and a second connector portion. First and second covers are pivotally attached to the body about a common axis for covering the first and second connector portion.
摘要:
An electrical connector including a receptacle terminal having a tubular member configured to receive at least a portion of a plug-type terminal. The receptacle terminal includes a slot extending axially along at least a portion of said tubular member and a resiliently expandable member disposed around the tubular member.
摘要:
A casting ladle has a body (2) with a base (3) and walls (4, 6, 8) made of a laminated composite ceramic material that includes multiple layers of a woven fiber reinforcing fabric embedded in a ceramic matrix. A rigid support element (20) for attaching the ladle to a handling device is embedded within the composite ceramic material. In a preferred form, the reinforcing fabric is made of woven glass and the matrix material includes calcium silicate and silica.
摘要:
Patients with aggressive breast cancer, including patients with estrogen receptor (ER) negative tumors and/or patients who have a disease-free interval from diagnosis to metastatic relapse of less than 36 months, have greater survival times than by treatment with DPPE and doxorubicin than patients receiving doxorubicin alone. Greater survival times are also achieved in patients receiving more than four cycles of treatment with DPPE and doxorubicin rather than doxorubicin alone. Greater survival times by treatment with DPPE and doxorubicin as compared to doxorubicin alone are further obtained in patients with metastatic breast cancer and who either have had no prior chemotherapy or no prior treatment type.
摘要:
A control pin (12) for controlling the flow of liquid metal in a casting process includes an elongate body member (34), the body member being made at least partially of a composite ceramic material that includes a fibrous reinforcing material embedded within a ceramic matrix. The body member (34) is preferably hollow and includes a wear-resistant tip (36) at one end.
摘要:
Methods of treating cancer using antisense oligonucleotides directed against DNA double-strand break repair proteins such as BRCA2 or RAD51 are provided. The antisense oligonucleotides can be used alone, in tandem or in combination with other cancer therapies, in particular with therapies that lead to DNA damage, inhibition of DNA repair or inhibition of DNA synthesis, such as radiation, platinum drugs, alkylating agents, PARP inhibitors, or inhibitors of thymidylate synthase.
摘要:
Methods, apparatus, and systems for deploying and retrieving sensors downhole are provided. The apparatus can include an outer tubular member disposed about one or more inner tubular members coupled to a fluid directional controller. The fluid directional controller may include a housing separating an interior cavity from an external environment of the wellbore. One end of the outer tubular member and at least one end of an inner tubular member may communicate with the interior cavity. The housing may also include a passageway configured to provide fluid communication between the interior cavity and the external environment. A flow control device may selectively facilitate fluid flow through the passageway. Accordingly, a sensor located in the interior cavity may be selectively exposed to fluid from the external environment. Sensors may be deployed by flowing fluid through a particular tubular member in one direction and retrieved by flowing fluid in another direction.
