1. A tool for use on generally tubular workpieces, said tool comprising:
a clamp assembly having an opening;
a first jaw coupled to the clamp assembly with a first linkage, at least a portion of the first jaw being moveable within the opening;
a second jaw coupled to the clamp assembly with a second linkage, at least a portion of the second jaw being moveable within the opening; wherein
each of the jaws comprises a generally semi-cylindrical smooth, curvilinear workpiece contacting surface shaped to complement a selected of the generally tubular workpieces and bounded by edges;
wherein at least one of said jaws is configured to be movable parallel to the other jaw via at least one of said linkages when moving towards and away from the other jaw; and
wherein at least one of the surfaces carries one of a gel or a patch to be applied to the selected workpiece.
2. The tool according to claim 1, wherein the tool is adapted to apply a selected treatment to the one of the gel or patch and to the workpiece, wherein the selected treatment is at least one of a group of treatments consisting of pressure treatments, chemical treatments, thermo-chemical treatments and electro-chemical treatments.
3. The tool according to claim 1, wherein the at least one of the surfaces carrying the one of a gel or patch to be applied to the selected workpiece further comprises a relieved area for accommodating, at least in part, the one of a gel or patch.
4. The tool according to claim 3, wherein the tool is adapted to apply a selected treatment to the one of the gel or patch and to the workpiece, wherein the selected treatment is at least one of a group of treatments consisting of pressure treatments, chemical treatments, thermo-chemical treatments and electro-chemical treatments.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An automatically openable garbage container through infrared induction, comprising:
a garbage container, having at least one opening for littering at one side, and a cover mounted on said opening for littering in moveable manner from a opening position to a closing position;
an infrared induction device, mounted in the garbage container above said opening for littering, comprises an infrared transmitting tube and a infrared receiving tube, wherein said infrared transmitting tube transmits infrared pulse signals in front of the opening for littering forming a induction area, and said infrared receiving tube receives the infrared pulse signals reflected by a barrier in said induction area and converts said infrared pulse signals to corresponding electric signals;
an automatic cover-opening device mechanically connected with said cover via a cable; and
a control unit communicatively connected with said infrared induction device and said automatic cover-opening device,
wherein said automatic cover-opening device comprises:
a driving motor connected with said control unit;
a first set of reduction gears connected to the output shaft of said driving motor to be driven;
a cable-collecting wheel connected with said first set of reduction gears wherein one end of said cable is connected to said cable-collecting wheel, and the other end is connected to said cover;
a second set of reduction gears connecting to the output shaft of said cable-collecting wheel to drive said cable-collecting wheel; and
a cam connecting to the output shaft of said second set of reduction gears to be driven, that can rotate to touch a cover-opening stroke switch and a cover-closing stroke switch respectively, wherein said cover-opening stroke switch and cover-closing stroke switch is electrically connected with said control unit via a wire.
2. The automatically openable garbage container through infrared induction, as recited in claim 1, wherein said automatic cover-opening device is mounted in a casing mounted on the upper inner side of said garbage container.
3. The automatically openable garbage container through infrared induction, as recited in claim 2, wherein, when said cover is in opening position, said cam rotates happening to touch said cover-opening stroke switch, meanwhile said cover-opening stroke switch sends a signal to said control unit to control said driving motor to stop rotating, and the friction of said first set of reduction gears, said second set of reduction gears and said driving motor is larger than the weight of said cover.
4. The automatically openable garbage container through infrared induction, as recited in claim 3, wherein, when said cover is in opening position, said infrared transmitting tube keeps sending infrared pulses signals to said induction area, and said cover does not close until said infrared receiving tube can not receive the infrared pulses signals reflected by said barrier.
5. The automatically openable garbage container through infrared induction, as recited in claim 4, wherein, when said cover is in closing position, said cam rotates happening to touch said cover-closing stroke switch, meanwhile said cover-closing stroke switch sends a signal to said control unit to control said driving motor to stop rotating.
6. The automatically openable garbage container through infrared induction, as recited in claim 5, wherein said garbage container further comprises an electric motor positive and negative turn driving circuit to connect said control unit with said driving motor.
7. The automatically openable garbage container through infrared induction, as recited in claim 6, wherein garbage container further comprises a infrared driving circuit, an amplifying circuit, and a comparative circuit, wherein said control unit is connected with said infrared transmitting tube through said infrared driving circuit, and said infrared receiving tube is connected with said control unit through said amplifying circuit and said comparative circuit.
8. The automatically openable garbage container through infrared induction, as recited in claim 7, wherein the output of said first set of reduction gears in mechanically connected with the input of said second set of reduction gears.
9. The automatically openable garbage container through infrared induction, as recited in claim 1, wherein said cover is pivotally mounted on a shaft base via a shaft.
10. The automatically openable garbage container through infrared induction, as recited in claim 1, wherein said cam comprises two pin rods or swing rods having a predetermined separated angle respectively, wherein said two pin rods or swing rods touch said cover-opening stroke switch and cover-closing stroke switch respectively.
