A string puller for selectively adjusting the pitch of the string(s) of a stringed musical instrument. Each string of the instrument is attached to a respective string puller. Each string puller comprises a pivoting member rotatably mounted on a pivot at a pivot support on the pivoting member. The pivoting member has a knife-edge surface which supports the string such that contact of the string at a first end of the scale ends at said knife-edge surface throughout a normal range of pivoting of s...

An elongated flexible cutting string, or substantially self-supporting strut cutting element, is connectable to a rotating device for use in a method of cutting vegetation. The cutting string has numerous advantages over conventional cutting strings, having a drag coefficient which is at least about 5% (e.g. 10-300%) less than the drag coefficient of a string having a substantially round and smooth cross-section. The drag coefficient of aerodynamic line 10 is 1.0 or less, e.g. about 0.35 or less...

A flasher string which includes a plurality of flashers connected in series and a plurality of thyrsitor diodes, each thyrsitor diode connected to a respective flasher in parallel. The flasher can periodically turn on and off to produce a twinkling light due to thermal distortion of the metal piece in the flasher. When the flasher turns on, the metal piece normally contacting the filament of the flasher is heated to expand and then escapes from the filament so as to turn off the flasher. Sequent...

A string support assembly for a musical instrument includes a base member and a pair of string support members which cooperate to support a string. The string support members have cylindrical shank sections which are received in openings in a base member. Head sections are connected to the shank sections. The head sections have arcuate side surfaces which engage the string. In one embodiment of the invention, the arcuate side surfaces on the head sections are conical. In another embodiment of th...

An action toy that includes a circular top which is fastened between two sets of strings, so that when the top is rotated manually, the strings become wound up, whereby when the string ends are then pulled, the strings unwind causing the top to spin, at high speed and then rewind the strings in opposite directions for reciprocal pull of the strings and additional top spinning; the top being made generally of two hollow, hemispherical transparent members secured to opposite sides of a circular di...

A string stapler comprising a stapling gun, a string guide guiding string from a spool to a position under the staple outlet of the gun whereby an operator can dispense string and also staple the string in place with a same unit, a hollow string-spool axle being mounted at the air inlet of the gun.

A string instrument including a body; a headstock; a neck extending between the body and the headstock; and a plurality of tuning mechanisms retained by the headstock and each having a stem with a tuning end and a connection end. Also included are a plurality of strings each having one end connected to the body and an opposite end connected to a different connection end; and a cover covering each connection end and shaped and arranged to prevent physical access to the opposite end connected ther...

A string remover for breaking and removing encircling string or twine bale securing members, is disclosed. A plurality of generally parallel fingers are placed straddling the string and are caused to rotate. The string wraps about the fingers and is tensioned to the point of breaking. After it has broken, it continues to be wrapped about the fingers. A slideable push-off plate is then moved axially along the fingers and forces the wound up string off the fingers so that it can be disposed of. Th...

A string is provided which has been stabilized to retain its initial tension over a long period when strung in a racket, and which has a high ratio of tensile strength to modulus of Elasticity to cause the deflection of the string woven membrane to be almost linear with applied force. The string has a very low Modulus of elasticity to cause the region of the string in the vicinity of the ball impact point to stretch easily and provide a cup for the ball at the moment of highest string membrane d...
