Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
95 words
An apparatus for soldering together two parts of which at least one is tinned, comprising resilient means for pressing together the parts to be soldered, means for supplying heat to the parts to be soldered, and means responsive to movement of the parts to be soldered together towards each other and serving for switching off the means for heating the parts to be soldered when the parts to be soldered together have approached each other within a distance amounting to at least 50 percent of the thickness of the original tin layer separating said part.
Claim 2
Independent Claim
95 words
An apparatus for soldering together two parts of which at least one is tinned, comprising resilient means for pressing together the parts to be soldered, means for supplying heat to the parts to be soldered, and means responsive to movement of the parts to be soldered together towards each other and serving for switching off the means for heating the parts to be soldered when the parts to be soldered together have approached each other within a distance amounting to at least 50 percent of the thickness of the original tin layer separating said part.
Claim 3
Dependent Claim
42 words
An apparatus in accordance with claim 1, comprising a gauge responsive to relative movement between parts to be soldered, and means for providing an electrical signal for stopping heating of the parts to be soldered when the gauge reaches a preset reading.
Claim 4
Dependent Claim
21 words
An apparatus in accordance with claim 2, comprising photoelectric means for giving a signal when the gauge reaches the preset reading.
Claim 5
Dependent Claim
61 words
An apparatus in accordance with claim 2, in which the gauge is arranged to move a metal plate, and the apparatus comprises a condenser part cooperating with the metal plate in providing a condenser whose capacity depends upon the position of the hand, and electronic circuit means for giving a signal when the capacity of the condenser reaches a preset value.
Claim 6
Dependent Claim
28 words
An apparatus in accordance with claim 1, comprising a gauge for indicating relative movement between the parts to be soldered, and vibrating means for acting on the gauge.
Claim 7
Dependent Claim
20 words
An apparatus in accordance with claim 1, comprising a resiliently acting metal band for pressing parts to be soldered together.
Claim 8
Dependent Claim
40 words
An apparatus in accordance with claim 6, in which the band has the shape of a letter U, the limbs of the band having resilient bends in them for exerting a pressing action on the two parts to be soldered.
Claim 9
Dependent Claim
35 words
An apparatus in accordance with claim 1, comprising timing means for indicating the time elapsing from the initiation of heating for soldering and the beginning of relative movement between the two parts to be soldered.
