Abstract: 262,753. Manufacture de Machines Auxiliaires pour l'ElectricitÚ et l'Industrie. Dec. 10, 1925, [Convention date].. Heating by circulation of fluids.-An apparatus for heating by the circulation of hot oil is. provided with an expansion vessel having a level indicator, and with thermostatic means for controlling the circulation either by thermo-siphon or by a pump. An oil heater 1 is connected by pipes 2 to a device 3 to be heated, and by pipes 5, 4 to the atmosphere. An expansion vessel 7 has a level indicator 8 and is directly connected to the boiler by a pipe 9. The valve 6 is closed during working, and oil is forced by expansion in the system to in the pipe 9. Oil is supplied to the system from a tank 10, and any overflow from the vessel 7 returns through pipe 13 to the tank 10. The temperature in the heater 1 may be controlled by a thermostat. A pump 14 may be connected in a by-pass 15 so that it may be employed to assist circulation of the oil by opening valve 19 and closing valves 17, 18. The circulation is then in the direction of the arrows, but when the pump is not operating it is in the opposite direction. The two methods may be alternated to effect a uniform heating of the device 3. A device for automatically changing over on accidental stopping of the pump is shown in Fig. 3. A thermometer with an indicator 21 is placed at the point of highest temperature of the heater ], and contacts with a conductor 22 to complete an electric circuit which includes electromagnets 23, 24 so that the valves 17, 18 are opened, and the valve 19 closed. In an alternative form, the thermometer may be placed at the bottom of the device 3, so that if, during thermo-siphon circulation the pointer 21 falls below the contact 22, the electromagnets are no longer energized, and the pump is brought into operation.

Title: Push-button operated bipolar fault current protective circuit breaker
IPC: H01H71/24
Filed: 1974-07-03
Abstract: 1461666 Bipolar circuit breaker ELLENBERGER & POENSGEN GmbH 3 July 1974 [31 July 1973] 29511/74 Heading H1N A two-pole circuit breaker electromagnetically tripped by fault current is provided with a quick make-and-break contact operating mechanism in the form of a cranked lever 8 of insulating material, one limb 9 carrying a cross-member 15 pivotally disposed in a slot 14 and the other limb 7 being disposed transversely on a switch bar 6 which passes through a hole providing large clearance so that the crank can both tilt on the switch bar and move axially of it. The cross-member 15 carries a moving contact 17 at each end, these co-operating with fixed contacts 18 connected to terminals 19. The moving contacts are carried on strips 16 connected via braids 20 to terminals 21. The transverse crank arm 7 carries projections 10 which are supported on shoulders 11 on the lower end of the switching bar, the arm being retained, in the "closed" position, by a latch 37 on the armature 35. The upper end of the switch bar 6 is connected to a push-button 4 depressed against the action of a spring 23 which is more powerful than the spring 22 at the other end of the bar. Energization of electromagnet 28 by a predetermined fault current attracts armature 35, releasing crank 8 which rises with the switch bar, due to spring 23, until it abuts the stop 41 which causes the bell-crank to assume a tilted position (Fig. 5, not shown), thus bringing the abutment 13 on the lower limb into register with a drive member 12 on the switch bar. Subsequent depression of the push-button causes engagement of 12 and 13 to carry the crank down with the switch bar until the latch 37 engages over the limb 7 by the action of spring 36. Release of pressure on the pushbutton then allows the switch bar to move up slightly, the crank 8 pivoting about the latch 37 to bring the contacts 17 and 18 into engagement. If the push-button is depressed under fault conditions, trip-free operation is provided by the spring 22 which forces the crank up the switch-bar when the armature 35 is attracted. A projection 25 on the lower end of the switch bar closes a spring contact 26 to connect the electromagnet coil 30 to the contacts 39, 40 for a pair of test-buttons 38.
