An A-Frame solar panel array system is configured to produce a high amount of electrical power for a given amount of ground space with a plurality of solar panels on both a forward beam and a plurality of solar panels on a trailing beam in an elevated position above the ground. This elevated positioning enables more solar panels to be configured over a given amount of ground area. The solar panels are spaced along the trailing and forward beams with a vertical offset between the trailing and forward beams to enable sunlight to pass therethrough to enable exposure to sunlight, through the forward beam array of solar panels onto the trailing beam array of solar panels. A solar panel actuator is configured to rotate the solar panels for increasing solar panel exposure throughout the year. The solar panels may only be configured to rotate trailing/forward.

The invention provides for protection of life safety, property and the liability thereof, by means of a intrinsically safe unpressurized storage tank water heater while producing hot pressurized water. The design addresses, with effect, convection, radiation, conduction and evaporative heat energy losses. Heat lost returned as usable hot water resulting in ultra-low standing loss. The stationary water medium prevents sedimentation, fouling of the heating element and gases expelled. Being dielectrically isolated, the medium may also be treated to further reduce corrosion. The design allows for a quick recovery rate and provides adjustable volume of hot water, being stackable, stage able, renewable, repairable and recyclable.

A hammer assembly for a grand piano comprising: a hammer, a hammer shank, a tubular lever interface, and a moveable knuckle. 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.

A universal grand piano piano action that has adjustable connections between the repetition base, heel, and rest cushion bracket of the piano action to provide a piano action that can be adjusted to fit any grand piano. Other components of the grand piano piano action, such as the jack and flanges, may require specific design and manufacture for each brand of grand piano. Universal grand piano piano action also allows true simultaneous half stroke keyboard design for both the white and sharp keys of a piano and includes the methods for installing simultaneous half stroke keyboard design into a grand piano.

Composite or plastic molded articles used in a grand piano action. A piano action actuates in response to depression on a piano key to swing a hammer into a piano string. The articles are assembled to form a piano action with significantly less dynamic mass which is much more responsive to the touch. In addition, the new action provides the valuable collateral benefits of increased efficiency of manufacture and maintenance. The invention also provides the capability to achieve true half stroke design in both the sharp and white keys. Additionally, the application discloses a universal composite grand piano action that is capable of being installed into any brand of grand piano.

A hammer shank and a separate shank butt component for a grand piano hammer assembly with increased rigidity, reduced inertia, 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. 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.

Composite or plastic molded articles used in a grand piano piano action. The articles make up a piano action with less dynamic mass which is, thus, more responsive to the piano player. In addition, the new action provides the extremely valuable collateral benefits of increased efficiency of manufacture and maintenance. Low inertia grand piano piano action comprises a repetition base with one or more of the following: an angled main beam, an angled balancier support beam, an integrated jack button stop, and a means to optionally connect a rest cushion assembly. Low inertia grand piano piano action may also comprise a heel with extremely low mass.

An improved key pin and action pin that is resistant to corrosion, is very durable and has surfaces with a very low coefficient of friction. The pins are preferably made of aluminum or aluminum alloy with a hardened anodized oxide surface. The anodized pins may be polished to provide a surface with a very low coefficient of friction that is also very durable. As a consequence of the low friction and corrosion resistance, piano actions using the pins have less resistance providing an action with a lighter 'feel' and consistency. Longevity of the components of the action and the pins is also greatly improved especially for pianos located in humid climates where traditional pins experience corrosion.
