Patent CA-2232477-A1 (CA)
Title: Automatic filler of liquid
Inventor: WANG SHAOYING
IPC: B67D3/02
Filed: 1998-05-19
Abstract: When filling a glass with beer, the foam always fills the glass first. The glass can be only filled with beer when the foam dissipates. However, it is necessary to fill a glass of beer several times. Solving this problem has been a concern for a long time.  According to the pressure difference between two points at different heights of a tight container which is filled by liquid, the liquid will flow out from the lower hole and air will enter the container from a higher hole, if the two holes are opened. An automatic filler of liquid has been designed according to this principle. Two rubber tubes as two holes in this apparatus are installed at proper heights. Liquid flows out from one of the rubber tubes (e.g. outlet of liquid) and air enters the container through the other rubber tube (e.g. inlet of air). The foam and the superfluous liquid can be sucked back into the container through the inlet of air under the effect of pressure difference. The desired level of beer filled in glass can be controlled. The beer can be filled once to a desired level and an overflow cannot occur.

Title: Improved strings for musical instruments
Inventor: HEBESTREIT CHARLES G
IPC: G10D3/10
Filed: 1996-09-23
Abstract: An improved musical instrument string is pro-vided. The string (18) includes a polymer cover (26) that protects the string (16), from contamination while maintaining the original "lively" sound of the musical string. By supplying the cover (26) over a conventional string (16) and preferably over a conventional wound string, the string (16) is protected against contamination while also making the string easier to play. The pre-ferred cover comprises at least one layer of expanded polytetrafluoroethylene (ePTFE) that is most preferably sealed with a polymer coating. In particularly preferred embodiments, a cover is applied over a portion of the length of the string having a relatively reduced variable mass. The result is that the string has relatively uniform mass along its entire length thereby assuring correct in-tonation.
