摘要:
A portable, adjustable golf training and teaching device when attached to the golfers hat, assists in head, chin, spine and eye adjustment. The present invention can be adjusted in the address or set-up position to allow the players shoulders to rotate freely under the chin unrestricted, also maximizes the shoulder rotation during the backswing. With the device attached to the brim of a golfer's hat and the viewing holes properly set the device produces a stereo or three dimensional view of the containment area around the golf ball to allow the golfer to monitor any movement in the golf swing. The present invention allows the golfer to view the target and the ball in flight after being struck. The device can be used to train, practice and play on the golf course.

A golf training and teaching device is provided for a golfer wearing a hat having a brim. The device includes a right-side L-shaped member and a left-side L-shaped member. The right-side L-shaped member includes an upper leg and a lower leg depending from the upper leg, with the lower leg having a sighting opening therein configured to be positioned adjacent the right eye of the golfer. The left-side L-shaped member includes an upper leg and a lower leg depending from the upper leg, with the lower leg having a sighting opening therein configured to be positioned adjacent the left eye of the golfer. The right-side and left-side L-shaped members are slidably coupled in partially overlapping relation so that the respective upper legs thereof overlay and define a clamp to be secured onto the brim of the hat. The sighting openings are configured to provide a visual containment area for a golf ball positioned adjacent the golfer's feet.

A measuring tool which has a first arm and a second arm where at least one of the arms is able to pivot so that the arms can be set at a variety of angles with respect to one another. The tool also has an angle scale and a pointer. The angle scale runs along the first arm and the pointer is able to pivot so that it can point to a variety of positions along the angle scale to give the angle between the arms, the pointer being arranged such that it can be swung away from and clear of the angle scale.

In a process for removing iodide compounds from a liquid composition comprising carboxylic acids having 2 to 6 carbon atoms or anhydrides thereof, by passing the liquid composition through a silver, mercury, palladium and/or rhodium-exchanged strong acid cation exchange resin, prior to contacting with the metal-exchanged resin the composition is contacted with a cation exchanger in the acid form to remove at least a portion of the metal ion contaminants in the liquid composition which have been found to displace the silver, mercury, palladium and/or rhodium from the metal-exchanged resin.

The present invention discloses novel recombinant DNA cloning vectors for use in Streptomyces and related organisms. These novel cloning vectors contain genetic markers that provide antibiotic resistance or colorimetric selectivity to the host cells. The invention further comprises transformants of the aforementioned vectors.

Disclosed is a container especially adapted for use in storing and heating comestibles intended for final preparation in microwave ovens. The container comprises a molded pulp tray, having a plastic film, preferably a polyester, adhered to its product-contacting surfaces. The container exhibits high strength and excellent product protection, but yet is low in cost. The process for making the container takes advantage of the porous nature of the pulp tray by drawing a vacuum directly through the tray to draw a film of heated plastic into adhering contact. The film is preferably extruded as the tray, carried in a vacuum mold, passes directly under the extruder.

Embodiments of the invention feature methods and apparatus for the efficient utilization of detectors and other components. The apparatus comprises a pump for receiving and propelling one or more samples in a fluid path. The apparatus further comprises a valve element in fluid communication with the pump for receiving the samples from the pump and directing the sample along one fluid path selected from a group. The group comprises a delay path comprising a delay volume, and a chromatography assembly having at least one chromatography column. The apparatus further comprises a detector or grouping of detectors in fluid communication with the delay path and the chromatography assembly for detecting compounds of interest to allow a single detector or single grouping of detectors to receive samples from the two fluid paths.

An apparatus for winding wire upon a reel or spool includes a support for receiving the reel thereon. A spindle arm coupled to the reel support is received within an annular bearing surface of a spindle support for rotation about an axis through the annular bearing surface. A drive member, such as a Kelly Bar provided on a boom of a digger/derrick truck, may be received within a bore associated with the spindle to rotate the spindle and reel support. A reel supported on the reel support is thereby rotated to wind wire onto the reel.

A canister endwall for use as part of a reaction canister of an airbag module for securing an airbag inflator. The airbag inflator has a cylindrical inflator sidewall of a predetermined diameter that ends in a tapered portion of the inflator sidewall that tapers radially inwardly to one end of the airbag inflator having an inflator flange. The inflator flange extends radially outwardly from the tapered portion of the inflator sidewall but has a diameter that is smaller than the diameter of the inflator sidewall. The canister endwall has an inner edge defining an airbag inflator mounting hole and a truncated conical array of a plurality of resilient fingers extending from the inner edge. The inner edge of the canister endwall is sized and shaped to allow passage of the inflator flange of the airbag inflator and engage the tapered portion of the inflator sidewall in a substantially gas-tight manner, and the truncated conical array of the plurality of resilient fingers is sized to butt against the inflator flange when the tapered portion of the inflator sidewall is engaged with the inner edge. The plurality of resilient fingers are bendable to allow passage of the inflator flange and, once the inflator flange passes through the truncated conical array of the plurality of resilient fingers, to spring back and butt against the inflator flange to prevent the inflator flange from being pulled out of the airbag inflator mounting hole.
