摘要： A muffler mechanism that reduces the volume of an acoustic piano without altering the feel of the piano to a human pianist. One embodiment includes a highly configurable piano muffler kit that may be mounted into pianos of various models. The muffler mechanism includes a cushioning member, which muffles the sound of the hammer striking the string and reduces the volume of the sound made by the string's vibration. The muffler mechanism also includes shims that may be used to position the cushioning member between a hammer let-off position and the string. This may allow for muffled piano playing without a noticeable change in the resistance of the keys. The muffler mechanism is mounted using brackets with a relatively small footprint. This allows the piano muffler to be installed without removing all of the dampers.
摘要翻译：消声器机构可以减轻钢琴的音量，而不会改变钢琴对钢琴人的感觉。一个实施例包括高度可配置的钢琴消声器套件，其可以安装到各种型号的钢琴中。消声器机构包括缓冲构件，该缓冲构件将敲击琴弦的锤的声音消除，并减小由弦的振动产生的声音的音量。消声器机构还包括可用于将缓冲构件定位在锤子释放位置和弦之间的垫片。这可能允许无声的钢琴演奏，而键的阻力没有明显变化。消声器机构使用相对较小占地面积的支架安装。这样可以安装钢琴消声器，而不需要拆除所有的阻尼器。

摘要： Apparatus and method utilize an open-top hopper having an upper cascade-zone and a lower pool-zone. Crude snow-debris is intermittently dumped into the hopper open-top and there operationally admixed with low-temperature water; this admixture is converted by cascade-zone comminution drums into a rough-slurry that pools at the pool-zone. Within the pool-zone, the rough-slurry is agitated, preferably with a revolvable bladed shaft, into a smoothly flowable-slurry that is dischargeable through an apparatus outlet to a remote disposal site which might be a municipal sewerline. Preferably, the apparatus takes the form of a wheeled vehicle, has a lengthily agitated pool-zone extending beyond the hopper, and is equippable with other desireable optional structural features.
