The present invention provides an indicator and indicator cartridge that shows the amount of material on a roll. The roll preferably has at least one toothed sprocket, the indicator, and includes a rotatable rod which is rotated through engagement with the rotating roll. At one end of the rod, a pinion gear is fixed to engage the toothed sprocket. An indicator member is slidingly configured to engage the rod such that the rotation is at least partially converted to linear motion of the indicator member. The rod and the indicator member are preferably threaded. A reference point is included for showing the linear displacement of the indicator member relative to the rod.

An indicator device for alerting the driver of a pickup truck to the orientation of the tailgate includes a housing assembly and an indicator assembly carried by and extending from the housing assembly. The housing assembly is attached to the tailgate of the pickup truck in a position that causes at least a portion of the indicator assembly to extend from the side of the truck so that the driver can see the extending portion in the side view mirror of the truck. Viewing the position of the indicator assembly allows the driver of the truck to ascertain the position of the tailgate.

A warning device for vehicles involved in an accident consists of one or more ejectable and instantly inflatable marker balloons with an inert gas that is lighter than air, which are deployed deflated and folded in holders distributed throughout the vehicle. The marker balloons have devices for automatic injection and inflation, connected to impact sensors throughout the vehicle, such that the balloons are ejected and inflated instantaneously in the event that one of the sensors detects a collision or impact.

A goal to ground indicator device indicates a ready and/or upset condition of a ground supported goal such as a soccer goal that has at least one bar that lies in contact with the ground. The indicator device includes a base plate, a contact arm mounted to the base plate and movable relative to the base plate and an indicator arm mounted to the base plate for cooperation with the contact arm. The contact arm and a portion of the base plate are configured for contact with the bar. The indicator arm is movable relative to the contact arm between a ready position and an upset position. The indicator arm is positioned such that a portion of the contact arm cooperates with a portion of the indicator arm to temporarily maintain the indicator arm in the ready position. A biasing element biases the indicator arm to the upset position. The contact arm resting in the base plate cooperates with the indicator arm against the biasing element to maintain the indicator arm in the ready position when the bar overlies the contact arm. When the bar is moved from the contact arm, the biasing element exerts a force to move the indicator arm from the ready position to move the contact arm from the base plate to disengage the indicator arm and to continue moving the indicator arm to the upset position. The contact arm can be mounted directly to the bar.

The invention discloses a falling object cooling type junction box for electrical equipment, and belongs to the technical field of junction boxs. According to the junction box, due to the arrangement of a normally-fixed hot soft body, a sleeving cooling piece, a heat absorption cooling ball and the like, when the temperature of an electric wire is too high, the normally-fixed hot soft body synchronous with the temperature of the electric wire is heated to be softened, and part of a reflective reminding rod falls into a transparent pipe. The reflective performance of the reflective reminding rod can play a reminding role, so that a worker can timely find the abnormal temperature phenomenon of the electric wire, further deterioration of an accident is prevented, meanwhile, a connector sleeving box and an electric wire sleeving block can fall downwards and sleeve an electric wire connector and an electric wire respectively, and a normally-closed ball outlet gap falls into clear water. Therefore, an effect of cooling the electric wire and the electric wire connector is provided, the temperature of the electric wire can be prevented from further rising within a certain time, the influence on other electric wires can be reduced, and the safety and the practicability are greatly improved.

A marker for the wingtip or other extremity of an aircraft. The marker includes a fabric pouch having a flap containing hook and loop fasteners, to hold the pouch on the aircraft extremity. A fabric tube extends outwardly and substantially horizontally from the pouch and supports a marker flag at its tip. The fabric tube contains a breakable support rod, so that if the aircraft wingtip collides with an object, the support rod will break and the flag will droop, providing a visible indication that a collision has occurred. The broken rod can then be replaced.

The invention discloses a high-stability transformer with an overheating early warning function, which belongs to the field of transformers. Through the arrangement of a light condensation strip, when the transformer is overheated, a thermal drop ring between a thermal moving block and a thermal coating pre-change rod is subjected to hot melting, so that the thermal moving block is unfixed, and the thermal moving block drives a magnetic moving light sheet to move downwards and gather together, the original light condensation strip with interval light emitting presents the phenomenon of bottom condensation light emitting, thereby realizing the overheating early warning effect for workers, and in addition, along with downward movement of the thermal moving block, the hot-melt thermal drop ring is gradually coated on the thermal coating pre-change rod, so that the color strip phenomenon is presented above the light emitting part. Due to double changes, the overheating early warning effect on workers is better, what is effectively guaranteed is that overheating is handled in time, the stability of the transformer is remarkably improved, and potential safety hazards possibly caused by overheating are greatly reduced.

A light assembly for a multiple-axle or movable axle vehicle with a vertical and horizontal arrangement of lights adapted to enhance visibility of the vehicle as well as the wheels and axles of the vehicle.
