20090178534 | HAMMER SHANK AND SHANK BUTT FOR PIANO - A hammer shank and shank butt for a grand piano with greatly improved rigidity and the collateral benefits of increased efficiency of manufacture and maintenance. Hammer shank comprises a long cylindrical member that is connected at one end to a traditional grand piano hammer and at the other end to a novel shank butt. Shank butt comprises: a hammer shank hole, a knuckle slot, a set of two flange attachment holes, and a void area. A traditional grand piano knuckle is attached to the knuckle slot. The shank butt is connected to the repetition flange of the piano. Thus, hammer shank is not directly connected to these members and thus can remain an integral cylindrical member without holes, notches, or voids, thereby allowing for a lighter, more rigid sub-member yielding hammer assembly with less mass. The invention provides the capability for a piano to be played with less touch weight on the keys and therefore provides a more responsive piano keyboard. The invention also allows for full “retrofitability” of hammer assembly into all existing grand piano brands. Embodiments include a composite shank butt that is a molded article and a composite hammer shank that is an extruded or molded article. | 07-16-2009 |

A grand piano tubular lever interface comprises: a deep socket; a set of two hinge pin attachment holes; a void area; and a moveable knuckle visual location system. A moveable knuckle comprises: a spline; a resilient core; a synthetic buckskin wear surface, and a moveable knuckle visual location system. Novel hammer assembly allows for a direct lever relationship between hammer shank and knuckle without requirement of a forked end hammer shank with knuckle slot. Best mode spline comprises: an upright rectangular portion and a wide base portion, wherein wide base portion includes an intricate shape. Intricate shape comprises: at least one recess area and at least one protrusion area. The inverse of intricate shape is included on the bottom of the tubular lever interface. Moveable knuckle visual location system further comprises at least one pointer located on the moveable knuckle which fits snuggly into one of several notches on the tubular lever interface. Moveable knuckle can be visually located onto tubular lever interface at any one of multiple distinct locations along a range that runs parallel to the length of the hammer shank and the length of tubular lever interface. The moveable knuckle visual location system allows for custom configuration of a specifically dimensioned hammer assembly with custom “tubular lever interface center-to center” dimension to refurbish any brand of grand piano from one stock-set of hammer assembly components. | 09-24-2009 |

20110208132 | Catheter adapter - A clam shell shaped adapter for retaining a catheter to establish a fluid path between the catheter and a fluid device or line has two shells integrally connected by a living hinge. A first shell has a luer end and a catheter end wherein a catheter is insertable through its aperture. A flexible tube at the inner surface of the first shell connects the luer end to the catheter end. The catheter is inserted through the catheter end to extend along the flexible tubing. A retainer structure is provided at the inner surface of the second shell so that when the first and second shells close upon each other, the retainer structure presses against the flexible tubing to fixedly retain the catheter in a fluidly sealing manner. Respective latch mechanisms provided at the shells lockingly couple the two shells to each other. The latch mechanisms are located remotely from the outer surfaces and peripheries of the shells to prevent inadvertent uncoupling of the shells. The shells may be uncoupled by inserting a pointed object through a notch to the interior of the device to disengage the latch mechanisms. | 08-25-2011 |
