Abstract: @ The disclosure is directed to a method and a tool for the replacement of any single connector pin (1) contained within a sizeable array of closely spaced very small connector pins on an electronic packaging structure (2) (substrate or module) without causing deleterious effects either to the remaining pins (1) or the substrate, which may be ceramic. 
     A pin gripper mechanism (10,11,12) is accurately positioned over the connector pin (1) to be replaced, the pin (1) is grasped with a pulling force (16) being applied. A stream of heated gas (8) is directed by a nozzle (7) onto the lower portion of the connector pin (1) which can be removed when the temperature reaches the reflow temperature of the alloy at the brazing joint. A replacement pin (1) is then inserted under pressure, with the heated gas (6,8) brazing the pin (1) in position.

Abstract: This invention relates to line circuits and, in particular, to the apparatus contained therein for switching the ringing signal on to the communication pair which connects the line circuit to the telephone station set which it serves. 
     Electromechanical relays provide an ideal switching function but require a significant amount of space while semiconductor switches do not require much space but provide an imperfect switching function which adversely affects the performance characteristics of the line circuit. 
     The subject ringing apparatus makes use of a semiconductor switch to provide the ring relay function and incorporates additional circuitry to eliminate the difficulties associated with semiconductor switches.

Abstract: A method of colour detection, in which electrical signals derived from two quantities, preferably orthogonal quantities, for example (R-L) and (B-L) are digitised. A time-shift is applied to the signals, either before or after digitisation, and a difference signal is formed between each original signal, and its time-shifted counterpart. The difference signals are then used as a key to a «lookup» table, to provide an output only when specified combinations of the two difference signals are encountered.

Abstract: A method and apparatus for monitoring the physical and chemical properties of a sample fluid by measuring an optical signal generated by a fluorescent substance and modulated by an absorber substance. The emission band of the fluorescent substance overlaps the absorption band of the absorber substance, and the degree of overlap is dependent on the physical and chemical properties of the sample fluid. The fluorescent substance and absorber substance are immobilized on a substrate so that an effective number of molecules thereof are sufficiently close for resonant energy transfer to occur, thereby providing highly efficient modulation of the fluorescent emissions of the fluorescent substance by the absorber substance.
