Title: Method for automatically tuning a string instrument, particularly an electric guitar
Inventor: ADAMS CHRISTOPHER
IPC: G10G7/02
Filed: 2005-01-19
Abstract: The invention relates to a method for automatically tuning a string instrument, particularly an electric guitar, wherein at least one string is tightened or loosened by means of a drive which is automatically driven by means of a control device and a string tightening device which is coupled to the drive in order to tune said string to a pre-definable chord root. The aim of the invention is to provide a method which functions without comparing an actual sound to a set sound (an actual frequency and a set frequency), in order to obtain a first initial tuning. The invention is characterized in that a traction force or corresponding torque that is applied by the drive in order to ensure that the string is maintained in a current state of tautness is determined for at least for one pre-tuning and said value is compared with a comparative value determined for the state of tautness of a correctly tuned string and if the value deviates from the comparative value, the drive is controlled in such a way that it ensures that the string is tightened by a force or torque corresponding to said comparative value.

Abstract: Systems and methods for player accounts for on-line lotteries and on-line games are described. A player establishes a player account and may associate tickets with the player account by identifying the player's account when purchasing a ticket. The player may identify the account in various ways. Each ticket purchased by the player is associated with the player's account. The player may then use an account checking service to obtain information about tickets associated with the player's account. The information provided may include results information, allowing a player to learn whether a ticket is winning ticket without manually checking the ticket. The system is operated using a lottery computer system that includes a lottery database. The lottery database is used to store ticket information relating to tickets, player account information relating to player accounts and ticket association information relating to associations between player account and tickets.

Title: Pipeline leakage-sensing device
Inventor: HARA ELMER H
IPC: G01M3/04
Filed: 2007-02-02
Abstract: A leakage-sensing device for installation adjacent to a pipeline configured for conveying liquid or gaseous chemical materials. The leakage-sensing device comprises a length of cable configured to transmit and back-reflect signals.  The cable is communicable with a signal-measuring device. The entire length of cable is encompassed by a torsioned and tensioned coiled biasing means. The cable and the torsioned and tensioned coiled biasing means are embedded in a chemically frangible casing material. The chemically frangible material is selected for its structural instability when contacted with the selected chemical material to be conveyed within the pipeline thereby releasing the torsioned and tensioned biasing means which subsequently imparts bending and/or twisting and/or elongating and/or contracting forces to the cable thereby causing the cable to physically interfere with and/or deform and/or break the transmission and back-reflection of signals along the cable.

Title: Foam pump with improved piston structure
Inventor: HAYES DAVID D
IPC: A47K5/14
Filed: 2009-01-21
Abstract: A foam pump includes a piston housing and a piston assembly received in the piston housing thereby defining a collapsible liquid chamber and a collapsible air chamber. The piston assembly includes a premix chamber separated from both the collapsible liquid chamber and the collapsible air chamber by a premix chamber wall and fluidly communicating with both the collapsible liquid chamber and the collapsible air chamber through a mix aperture in the premix chamber wall.
