A new and improved food warming appliance comprises a housing within which a multiplicity of elongated sanitary sleeves or cups are adapted to be removably mounted and within which cheese dispensing guns are adapted to be respectively disposed. Respectively surrounding each one of the elongated sanitary sleeves or cups is an elongated aluminum tube, and respectively surrounding each one of the elongated aluminum tubes is an elongated flexible foil tube which has a heating strip operatively associated therewith. To complete the assembly, a suitable elongated tubular insulation sleeve respectively surrounds each one of the elongated flexible foil tubes. In this manner, when the heating strips of the foil heaters are energized, heat is transmitted radially inwardly from the foil heaters, to the aluminum tubes, and then to the sanitary sleeves or cups for, in turn, heating the dispensing guns whereby, for example, the semi-solid cheese products, disposed within the cheese dispensing guns, are sufficiently heated to predetermined temperatures which not only melt the cheese products and provide the same with the requisite fluidity for easy and reliable dispensing, but also renders the cheese products safe for consumption. Still further, a food dispensing station is formed by the food warming appliance and the dispensing guns.

A power tool system includes a removable battery pack a first tool and a second tool. The first tool includes a first base housing that is selectively engageable with the removable battery pack and a first tool portion connected to the first base housing by a first connecting section. The second tool includes a second base housing that is selectively engageable with the removable battery pack and a second tool portion connected to the second base housing by a second connecting section. The second tool base housing houses a second controller that provides a proportional power delivery system for the second tool and second tool base housing also includes a second actuator for providing user control of the second tool.

A device for and method of using the device to dispense pourable material from one or more pouches is provided. The device comprises a pair of hinged plates between which one or more pouches can be positioned. The plates of the device are joined by a ratcheting element that secure the plates and any pouches positioned between them. When a squeezing force is applied to the plates, the plates exert pressure upon the one or more pouches to cause the contents of the pouch(es) to be expelled. The ratcheting element is adapted to adjust automatically in response to the force exerted upon the plates. A device adapted to heat and dispense the contents of the one or more pouches is also provided.

A three-dimensional drawing device can include a housing configured for to be held in user's hand, shaped to allow manipulation of the housing like a pen, and configured to accept a strand of thermoplastic material. The drawing device has a nozzle assembly with an exit nozzle and a motor connected to a gear train that engages the strand such that rotation of the motor causes the feed stock to be extruded out of the exit nozzle to form a three-dimensional object. The motor can be controlled using a variable speed control mechanism or first and second actuators, thereby controlling movement of the strand, for example, to advance or retract the strand relative to the nozzle assembly.

An improved cartridge structure that both heats the materials contained therein and provides for enhanced structure such that the bypass leaking of the low viscosity heated components is avoided. The cartridge is preferably formed from a rigid material such as reinforced fiberglass tubing. The wall of the cartridge is then wrapped in a flexible heating element or has a heating element cast directly in the wall thereof. The heating elements preferably heat the interior contents and epoxy cartridges to between 150 degrees and 180 degrees Fahrenheit. The wall structure may be of single wall construction with the heaters embedded therein or of a double wall construction such that the heaters are contained between an inner and outer wall. Further the wall construction is preferably formed to withstand the pressures applied when spray applying the epoxy contained therein to prevent the tube wall deformation and resulting blow by leakage.

A hot melt glue gun with a base includes a hot melt glue gun and an auxiliary base detachably mounted to the hot melt glue gun. The hot melt glue gun includes a bottom. The bottom is flat and includes two lateral sides. Each of the two lateral sides of the bottom includes a groove and a coupling groove in communication with the groove.

The auxiliary base includes a base body having a flat bottom and two arms extending from the flat bottom. Each of the two arms includes a coupling block. Each coupling block is detachably coupled with one of the coupling grooves.

A three-dimensional (3D) drawing pen can include a housing that has a port that permits insertion of a strand of material into the housing. The strand can be moved through the housing toward a nozzle assembly configured to permit the strand to be extruded out of the 3D drawing pen in a form that retains its shape against gravity in free space to draw a 3D object.

The first tool includes a first base housing that is selectively engageable with the removable battery pack and a first tool portion connected to the first base housing by a first connecting section. The second tool includes a second base housing that is selectively engageable with the removable battery pack and a second tool portion connected to the second base housing by a second connecting section. The second tool base housing houses a second controller that provides a proportional power delivery system for the second tool and second tool base housing also includes a second actuator for providing user control of the second tool.

An apparatus comprising a three-dimensional (3D) drawing pen can permit a user to draw a 3D object in free space that retains its shape against gravity. The 3D drawing pen can include a body, a sensor supported by the body, a motor, and a nozzle assembly disposed at a distal end of the body. The motor can drive material toward the nozzle assembly upon actuation by the sensor. The nozzle assembly can include an extruder and an exit nozzle. The extruder can have a heating element for melting material and permitting the material to be extruded out of the exit nozzle in a solid form upon actuation of the motor by the sensor. The user can manipulate the 3D drawing pen to draw a 3D object that retains its shape against gravity.
