摘要:
An intank oil cooler assembly comprises a plurality of manifold end connected, vertically stacked, elongated tubular panel subassemblies, containing structurally enhancing header manifold connector end post with external circular wide flanges, manifold intermediate spacer disc washers, and a base plate subassembly placed in a supporting bottom base position. Each thin-walled, tubular panel subassembly has header manifold inlet and outlet end sections, an internal central longitudinal flow channel region designed for conducting internal fluid flow, and also, has a turbulizer subassembly installed therein for causing internal fluid turbulization to optimize heat transfer. Each tubular panel subassembly is fabricated by laminating together paired, thin-walled plate elements having sidewalls embossed with dimpled exterior surface projections on their outer convex surface and axially corresponding reverse side dimpled depressions on their inner concave surface. Opposing tubular panel dimple surface projections are top end flattened and brazed externally together to position and form a geometrically desired fluid passageway between each thin-walled, tubular panel subassembly.
摘要:
A compensation circuit and method for compensating for variations in time delay adjustments of synchronizing circuits that synchronize an external clock signal applied to an integrated circuit with internal clock signals generated in the integrated circuit in response to the external clock signal. The time delay relationship between fine and coarse delay circuits of an adjustable delay circuit is adjusted to compensate for variations from an expected time delay relationship.

A game including a frame, a rotatable scoring assembly, and at least one playing piece. The at least one playing piece is thrown toward the rotatable scoring assembly, and points are scored by the playing piece coming to rest on predetermined portions of the scoring bar assembly.
摘要:
A magnetic rotational position sensor including first and second magnets spaced apart to define an air gap and cooperating with one another to generate a magnetic field within the air gap extending along an axis of rotation. At least one magnetic flux sensor is positioned within the magnetic field and is operable to sense varying magnitudes of magnetic flux in response to relative rotational movement between the magnetic field and the magnetic flux sensor about the axis of rotation.

An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed comprising a shaft having an insufflation channel extending along an axis between a proximal end and a distal end, the insufflation channel being adapted for connection to a source of fluid under pressure at the proximal end, a tip at the distal end of the shaft, and at least one vent hole formed at the tip or the shaft being in connection with the insufflation channel and being adapted to expel the fluid under pressure to insufflate the abdominal region. At least one of the tip and the shaft is formed of a translucent or transparent material such as polycarbonate to facilitate visualization of the abdominal wall and the abdominal region. The shaft includes a lumen extending along the axis between the proximal end and the distal end to enable insertion of a laparoscope. The lumen and insufflation channel may be formed as separate channels or as one shared channel. The tip may be blunt, the shaft and the tip may be integrally formed, and the vent hole may be of any geometric shape including round, oval, square and rectangular. The blunt tip may further comprise a marker to indicate penetration of the abdominal wall. In another aspect, the tip may be sharp, pointed or bladed to facilitate penetration of body tissue.

The present invention relates to isolated MEKK1 proteins, nucleic acid molecules having sequences that encode such proteins, and antibodies raised against such proteins. The present invention also includes methods to use such proteins to regulate apoptosis. The invention provides active fragments of MEKK1 proteins that are generated upon cleavage of MEKK1 with a caspase protease. These active fragments are capable of stimulating apoptosis. Moreover, the invention provides protease-resistant forms of MEKK1 proteins, that are resistant to cleavage by caspase proteases and that are capable of inhibiting apoptosis. Still further, the invention provides methods for generating an active fragment of MEKK1, methods of identifying modulators of the apoptotic activity of an active fragment of MEKK1 and methods of identifying modulators of caspase-mediated cleavage of MEKK1.
摘要:
A phase detector generates a first output signal if a feedback clock signal leads a reference clock signal by more than a first time. The phase detector generates a second output signal if the feedback clock signal lags the reference clock signal by more than a second time. If the feedback clock signal either leads the reference clock signal by less than the first time or lags the reference clock signal by less than the second time, neither output signal is generated. The phase detector may be used in a delay-lock loop in which the first and second output signals increase or decrease a delay of the reference clock signal by respective first and second delay increments. In such case, the each of the first and second delay increments should be less than the sum of the first and second times.

A method and system for assessing the project testing practices of an organization is provided. In one embodiment, a consultant gathers current testing practices documentation and procedures for the project and then conducts an interview of at least one project team member utilizing templates and procedures provided by a testing practices assessment toolkit. The consultant then enters the results of the interview and the information obtained from the testing practices documentation and procedures into the toolkit. The toolkit then calculates maturity scores for a select number of key focal areas using formulas based on the industry to which the project belongs. The consultant then analyzes the current situation in the select number of key focal areas against industry best practices using the maturity scores calculated by the toolkit as an aid. The consultant then determines recommendations for the organization that would improve the testing practices of the organization.
摘要:
A tissue welding apparatus is adapted to fuse a first piece of tissue to a second piece of tissue which are disposed in a surface proximate relationship. An elongate shaft carries a first jaw, and a second opposing jaw moveable relative to the first jaw. At least one penetrating member is carried by the first jaw and moveable relative to the second jaw to create a channel through the first piece of material and the second piece of material. A source of heat is coupled to the penetrating member for denaturing the tissue defining the channel. This denatured tissue forms a column binding the first piece of tissue to the second piece of tissue. A chemical agent can be carried to the tissue with the penetrating member.
摘要:
The invention comprises a decorative lid strap for securing the cover of a casserole to the top of the casserole or container so that the casserole can be transported safely while food and etc. is in the casserole. The lid strap has an elongated elastic strap with hooks mounted to the outer ends of the elastic strap so that the strap may be stretched over the top of the cover of the container and the hooks attached to the opposing handles of the container to secure the cover to the casserole or container. A decorative sleeve is removably mounted over the strap while the strap is mounted over the cover of the casserole.
