The mixing rotor has multiple vaned inner rotors with quarter-circle shaped multiple vanes and a vaned front rotor opposite to a second rotor axle of the mixing rotor with multiple vanes complementary to the multiple vanes of the multiple vaned inner rotors. The housing mounted to the connecting cover has at least two grooves disposed on the circular partition. Each of the at least two grooves has a spacer along each of the at least two grooves. The dynamic mixer head can enhance the mixing effect of two different component substances during rotation.

Abstract: The invention is related to a cartridge adaptor which comprises a first dual-barrel cartridge, a housing, an adaptor and a second dual-barrel cartridge. The first dual-barrel cartridge comprises two openings and is disposed in the housing. The housing comprises a first fastening component. The adaptor has two inlets which opposite to the two inlets. The two inlets are respectively mounted into and communicate with the two openings of the first dual-barrel cartridge. The two outlets communicate with the two inlets. The second dual-barrel cartridge comprises two openings and a second fastening component which is complementary to the first fastening component of the housing. The two openings of the second dual-barrel cartridge communicates with the two outlets of the adaptor. The invention prevents the remaining unmixed component substances from oozing out of the two inlets or the two outlets of the adaptor during the transfer process of the remaining component substances.

Abstract: A cable port identification system is disclosed that provides identification facilities for communication, data, other cabling and/or wires and the connectors to which they are coupled found in a multi-port station. In some implementations the identification facilities can include label retention and protection and may also include label magnification.

Abstract: A device for mixing and discharging plural materials has a body, a housing and a sealing plug. The body has multiple barrels and multiple tubes communicating with the barrels. The housing is rotatably attached to the body in a thread manner and has a mixing chamber and a discharging segment. The sealing plug is mounted in the mixing chamber to seal the tubes and has a sealing disk and multiple sealing sleeves. The sealing disk has multiple holes and multiple sealing lids mounted respectively in the holes, and each sealing lid has an outer edge connected detachably to the inner surface of a corresponding hole and having a thickness smaller than that of the sealing lid. The sealing sleeves are formed on the sealing disk, align respectively with the holes in the sealing disk and are mounted respectively around the tubes.

Abstract: A dental agent applicator has a barrel, a sealing plug, a delivery head and a plunger. The barrel has a proximal end, a distal end and a chamber defined through the barrel. The sealing plug is mounted in the chamber and hermetically obstructs the chamber. The delivery head is movably mounted on the distal end of the barrel and has a hub and a nozzle tip. The hub is mounted movably in the distal end and selectively moves the sealing plug to make the chamber communicate with the delivery head. The nozzle tip is mounted on the hub. The plunger is mounted slidably in the proximal end of the barrel. The delivery head is mounted permanently on the barrel. Using the dental agent applicator without having to replace any sealing cap with the delivery head is simple and convenient.

Abstract: A separating ring having a body being a resilient bent open ring and having two bent side bars having distal ends and wedge legs formed respectively on the distal ends, the wedge legs being spearheaded and fit easily between adjacent teeth to allow dental operations to be carried out easily and without the need for wedges.

Abstract: A dental impression tray has a base and a relator. The base has a biting portion and a handle. The biting portion is curved. The handle is formed on the biting portion and has an arc hole that is defined through the handle to receive impression material. The relator has a vertical bar and a horizontal bar. The relator is mounted in the arc hole and is fastened in the arc hole by impression material. The horizontal bar connects perpendicularly to the vertical bar. Therefore, the impression of the teeth to be crowned or veneered as well as the relation between the impression and the patient's face are obtained simultaneously.
