A hot melt glue gun provides a melt chamber for supplying melted glue to a discharge nozzle. An auxiliary chamber is connected to the melt chamber, and melted glue is drawn from the melt chamber into the auxiliary chamber when discharge of glue is terminated. The glue drawn from the melt chamber reduces the possibility of glue dripping from the discharge nozzle.

A coating system for coating objects comprises an application device and a supply system, by means of which at least one liquid material can be fed to the application device via a flow path. A temperature control arrangement is present, by which the temperature of the at least one liquid material can be controlled in the flow path and/or the application device in at least one temperature control region.

A heat pump dispenser includes a housing having a handle portion and a barrel portion. A feeder section is coupled to the handle portion. The feeder section includes a feeder mechanism and a dispensing trigger assembly operably coupled to the feeder mechanism. The feeder mechanism includes a gear assembly having a drive gear operably engaged to a plunger housed in the barrel portion. The trigger assembly includes a trigger having a ratchet portion. The ratchet portion selectively engages and rotates the drive gear to move the plunger toward a dispensing opening provided in the barrel portion and into engagement with an adhesive/filler stick. The feeder mechanism is selectively actuated by the dispensing trigger assembly to advance the adhesive/filler stick into a heater section of the barrel portion.

Apparatuses and methods for extruding a dental filling material into a tooth. The extrusion is accomplished by harnessing a combination of motor power (such as from an electrical motor) and spring loaded power. This combination overcomes the shortcomings of each of these power sources. In addition, because this combination significantly reduces battery power requirements, it allows for more thermal heating, down-packing, and obturation to be performed than would otherwise be possible.

A solder supply device provided with a solder cup housing liquid solder that is tubular and open at one end; a nozzle section, for ejecting solder from the solder container, that is inserted into the solder container; a flange section that is provided on an outer circumferential section of the nozzle section and that is engaged inside of the solder cup; and an outer tube that demarcates an air chamber with the bottom surface of the solder cup. Solder is supplied from the tip of the nozzle section by the solder cup and the flange section being relatively moved by supplying air to the air chamber. Solder is supplied from the solder container without using an air cylinder, electromagnetic motor, or the like.

Solder supply device includes solder cup that is tubular and open at one end, nozzle section for ejecting solder from the solder cup, flange section that is fixedly provided on an outer circumferential section of the nozzle section and that is engaged inside of the solder cup, and inner tube an end of which holds the nozzle section and the other end of which extends from the opening of the solder cup; the flange section is formed from material that is elastically deformable and the flange section is engaged inside the cup with an outer edge section of the flange section in an elastically deformed state. The elastic force arising between the outer edge section of the flange section and the solder cup is smaller than the holding force of the nozzle section by the inner tube.
