Title: Electronic circuit-breaker for transformer - thermocouple and resistor detect large and small overloads
IPC: H02H3/10
Filed: 1973-11-22
Abstract: The circuit-breaker which is used for transformer protection is tripped by two conditions. The first is a low overload which is detected across resistance in the windings. A photo-diode (18) senses the voltage across the resistance by means of a light-emitting diode (14) and trips the breaker via an amplifier. The second condition is a large overload which is detected by a thermo-couple inserted into a conductor in a beryllium oxide cup which has high electrical insulation but low thermal resistance. The thermo-couple causes a threshold circuit to trip which operates the circuit-breaker. This samples the transformer temperature accurately and overcomes the difficulties of complex mechanical circuit-breakers.

Title: Sensor for fluid level - uses electrically heated thermistor with sudden change from high to low resistance at temperature rise
IPC: G01F23/24
Filed: 1974-09-13
Abstract: A level sensor for producing a warning signal if the brake fluid for motor cars drops below a danger level consists of an electrical heating element (22) which is coupled by a heat transmitting connector (27) to a resistor (24). The latter is made of a material which suddenly changes from a high to a low resistance at a certain temperature. The sensor is attached by the fitting (26) to the brake fluid container. The preferred material for the resistor (24) is Ti3O5 which has a transition temperature of 165 deg.C. This eliminates the high temperature rise required by ordinary thermistors and has a desirable self-locking effect once a dropping fluid level has caused it to respond.
