Title: Rotor earth fault detection cct. for synchronous machines - uses part of exciter voltage as bias
IPC: G01R31/34
Filed: 1969-07-24
Abstract: The application is principally to brushless machines, and provides a means for contactless detection of an earth fault. The detecting element is connected to a suitable point on the exciter winding, for example the star point or a phase end such that sufficient voltage to earth is available to operate the detector in the event of an earth fault on the main machine field circuit. The detector is typically a trip fuse whose element melts during the substantial but transient flow of earth fault current. The trip indicator position can be detected by stationary equipment, for example by stroboscope. Alternatively a light source such as a neon lamp or light emitting diode can be connected across the fuse to give an optical indication of an earth fault.

Title: Analysing free chlorine content of chlorinated water - by amperometric cell with copper electrodes contacting flowing sample
IPC: G01N27/49
Filed: 1970-07-29
Abstract: A sample stream from a chlorinated water supply is passed through a cell without the addition of buffering agents. The cell includes a copper measuring electrode and a copper counter-electrode making contact with the sample stream. A direct voltage is applied across the electrodes with the measuring electrode being negative with respect to the counter-electrode and with the applied voltage causing the cell to operate in a saturation voltage zone. In this zone the current flow is proportional to the chlorine content and is independent of small changes in the applied voltage. The current flow is indicated on a meter calibrated in chlorine concentration. Preferably the meter reading is temperature compensated by the use of a shunt thermistor. The apparatus provides a continuous indication of free chlorine in a swimming pool. The use of buffering agent is eliminated and the electrodes remain active for a prolonged period.

Patent JP-H0254632-B2 (JP)
IPC: H01R24/00
Filed: 1982-01-29
Abstract: In an IC connector for connecting lead terminals of an IC package of the dual in-line type to terminals of a circuit board, first grooves and first projections are formed on two surfaces of a slide body. The main body has two walls each of which has a surface which has a plurality of second grooves and which opposes at least one surface of the slide body. One end of each connecting terminal is inserted in each second groove. The other end of each connecting terminal extends through each second groove to be connected to a predetermined terminal of the circuit board. The slide body is supported by a supporting means such that the slide body may be movable between a first position and a second position along the direction of arrangement of the second grooves. When the slide body is in the first position, the first and second grooves define gaps therebetween into which or from which the lead terminals may be inserted or removed. When the slide body is in the second position, the second grooves and first projections oppose each other so that the first projections urge the connecting terminals against the second grooves against the elastic force of the connecting terminals. When the lead terminals are inserted in the second grooves, the connecting terminals and the lead terminals are urged against each other.
