A golf club that is preferably made from fiber-reinforced plastic composite by an injection molding process. The preferred golf club head includes a striking face for striking a golf ball, an outer periphery, a cavity formed between the outer periphery and the back of the striking face, a sole enclosing the bottom portion of said cavity, and at least one elongate power bar extending across the cavity from the striking face to the outer periphery. The sole is preferably integrally formed with the face plate and outer periphery. The cavity of the golf club head opens to the top of the club head.

Methods and devices for reducing evaporation of sample materials from the wells of multiwell plates are disclosed which find particular utility when the plates are placed in a stacked configuration. An example of the methods includes providing at least a first multiwell plate which is configured to be placed in a stacked configuration with at least one second multiwell plate, the at least first multiwell plate having a plurality of wells for receiving sample material therein and opposing side walls which extend around the plate and which define a ridge spaced inwardly of the side walls and extending around the plate between the side walls and the plurality of wells, the method including at least partially filling the ridge with a liquid such as water or buffer solution. The ridge can include one or more ribs which extend upwardly from a lower surface of the ridge to help reduce sloshing of the liquid contained within the ridge and to add structural strength and rigidity to the multiwell plate. The second multiwell plate can be provided with a downwardly extending flange which extends around a lower surface of the plate and which is configured to be removably received by the ridge of the at least first multiwell plate such that when the second multiwell plate is removably positioned on top of the at least first multiwell plate in a stacked configuration, the flange extends at least partially into the ridge and contacts the liquid to thereby create a substantial evaporation barrier to minimize evaporation of sample liquids in the wells of the at least first multiwell plate.

A test strip for determining the concentration of an analyte in a body fluid includes a membrane in fluid communication with a porous layer. The membrane and the porous layer are divided into compressed portions, which restrict the capillary flow of the body fluid, and uncompressed portions. The uncompressed portions are adapted to absorb and retain body fluids in excess of the amount required for operation of the test strip. The test strip may be constructed with an internal relief chamber to accommodate the uncompressed portions. A method of making the test strip by pressure and/or heat sealing individual components on a shaping die is also provided.

Milling and drilling tools and soft tissue management techniques are provided for arthroplasty that facilitate intraoperative and postoperative efficacy and ease of use. In one embodiment, resiliently biased soft tissue protective sleeves surround a side cutting tool and are interposed along the longitudinal axis of the cutting tool, preferably adjacent each side of the bone. The soft tissue protective sleeves are biased to track along the contour of the side of the bone and prevent the cutting tool from being exposed to soft tissue during the resection. In another embodiment, a pilot drill is initially utilized to create an initial bore in the bone to be resected. The pilot drill preferably has an end cutting arrangement and a non-cutting removal channel that minimizes the tendency of the pilot drill bit to drift off-axis as the initial bore in the bone is created. Once the initial bore is created, the pilot drill bit is withdrawn and a second side cutting tool, such as a milling bit, is then inserted into the bore to perform the desired surface resection.

A throttle body fuel injection system and method that is arranged to easily replace four-barrel carburetors includes a throttle body assembly with four main bores, each with a throttle plate and an associated fuel injector. Each injector feeds fuel into a circular fuel distribution ring via a fuel injection conduit, which introduces pressurized fuel into the air stream. The fuel distribution rings and bores have profiles that avoid constrictions for to prevent low pressure zones according to the Venturi effect. Fuel is injected through downward-facing outlets at or near the bottom end of the rings. The fuel injection rings are two-piece, each formed of an insert pressed into an outer housing. The insert includes axial grooves intervaled about its exterior circumference of insert that are joined by a circumferential groove formed about the insert. The grooves are in fluid communication with a conduit that supplies fuel from a fuel injector.

A needle guard includes a clip with a canting wall to grip the needle shaft and a distal wall to block the tip thereof, wherein the canting and distal walls may be interconnected by an angled strut so as to allow the canting wall to be tilted over center in a ready state, a spring member, such as a leaf spring, may have a portion extending past an edge of the strut to bias the clip to grip the needle shaft, and the distal wall may be or include a stylus and have an L-shape to define a lip to help block the needle tip. The clip may have a depending heel to help pivot the clip about a ledge to grip the needle shaft. A needle support may be provided to limit flexure of the needle which might otherwise allow the needle to come loose from the clip. Arrangements for limiting rotation of the needle hub and needle guard housing are provided, as is a protective shroud to reduce the risk of inadvertent activation of the needle guard. Further, the needle guard may be used with a catheter assembly. Also provided is an improved duckbill release mechanism.

A manhole or catch basin assembly comprises separable component parts which assemble to a unitary structure, the component parts being readily replaced or interchanged to increase the vertical height of the assembly such as when a road surface is repaved to an elevated height; the component parts are molded parts which fit snugly together in sealing engagement.

A solid oxide fuel cell has anode, cathode and electrolyte layers each formed essentially of a multi-oxide ceramic material and having a far-from-equilibrium, metastable structure selected from the group consisting of nanocrystalline, nanocomposite and amorphous. The electrolyte layer has a matrix of the ceramic material, and is impervious and serves as a fast oxygen ion conductor. The electrolyte layer has a matrix of the ceramic material and a dopant dispersed therein in an amount substantially greater than its equilibrium solubility in the ceramic matrix. The anode layer includes a continuous surface area metallic phase in which electron conduction is provided by the metallic phase and the multi-oxide ceramic matrix provides ionic conduction.
