摘要:
A short-circuit fault indicator mechanism adapted for indicating a normal operating condition, a short-circuit condition and an OFF condition of a circuit breaker is disclosed. The short-circuit indicator mechanism comprises a slider, a solenoid, and a rotating arm. The slider is having a first end connecting to a first hook. The slider is having a second end connecting to a solenoid. The slider is slidably movable between a first position and a second position responsive to a plurality of operating conditions of the circuit breaker. The rotating arm is having a second hook that engages and/or disengages with the first hook in the first and second position of the slider respectively. The rotating arm is having an indication flag that indicates the plurality of operating conditions of the circuit breaker.

Seal for tubular heat exchanger comprising groove with an inner edge; tongue of the diaphragm having front face extending in the radial direction and inner edge parallel to the axis of the channel; the face extending beyond the radial width of the groove in inward direction and overlapping the face of the shoulder of the channel in which the groove being provided. The tongue of the diaphragm being thus kept away from entering the groove; the diaphragm having flexibility to permit deflection of the tongue, the tongue of the diaphragm being loaded from outer side by the internal compression ring, the said internal compression ring being loaded in turn by the threaded push bolts/rods being fitted in the threaded holes on periphery of the threaded lock ring. This load is ultimately transferred to the joint between the gasket and face to achieve leak-proof joint.

The present invention relates to an improved arc chamber/chute assembly in a circuit breaker for effective channelization of hot ionized gases through said arc chamber to enhance breaking capacity in circuit breakers. The assembly comprises back vent secured inside said arc chute assembly and front vent secured inside the assembly placed between the back vent and arc chute plates of the assembly. The front vent comprises a substantially T-shaped profile having a substantially horizontal portion along X-axis and a substantially vertical portion along Y-axis so as to define a substantially divergent nozzle profile in the said T- shaped profile such that at the time of high fault conditions in said arc chamber nozzle effect is generated due to high pressure build up in arc chamber assembly.

The various embodiments herein a self cleaning filter assembly for fluid or fuel dispensers is disclosed. The self cleaning filter assembly has a filter casing (102) in which a filter unit provided with a filter chamber is arranged inside. A filter mesh element is arranged in the filter chamber to filter the dust particles in the A check valve assembly is arranged inside or outside the filter unit. The check valve is lifted or opened under the fluid pressure to permit the flow of the fluid. Pluralities of balls with bristles are arranged freely inside the filter unit so that the balls with bristles (104) get tumbled inside the filter chamber due to the fluid flow inside the filter chamber to rub the filter mesh element continuously to clean the surface of the filter element.

The present invention describes a transmission-movement kinematic mechanism for auxiliary devices. The mechanism is having a transmission-movement kinematic mechanism and a trip-indicator kinematic mechanism having an indicator flag. The operating connection between the mechanism and the trip-indicator kinematic mechanism are made by a lever which can further engage with another lever for allowing the indicator flag to be moved in a visible position for determining any fault.
