摘要:
A container (10) for mixing and dispensing material includes a body (12) having a main chamber (17), a dispensing nozzle (26), a liquid receptacle (16) and a plunger (18). The liquid receptacle (16) has a front portion arranged to break away upon pressure being applied by the plunger (18) so that the plunger (18) can traverse the entire length of the body (12). This enables a charge of material in the main chamber (17) to be entirely dispensed through a frangible wall (22) into the nozzle (26). The container (10) is particularly envisaged for use in mixing and dispensing of dental material.
摘要:
A liquid container (10) has an outer wall (12) to which is mounted a liquid material receptacle (18). The liquid material receptacle has an open end (20) and a closed end (24). The open end (20) of the liquid material receptacle (18) is sealed by a membrane (34). Further, the liquid material receptacle (18) tapers inwardly from the open end (20) to the closed end (24).
摘要:
A method for a network device of a powerline communications network includes selecting between a default preamble signal and a network-specific preamble signal specific to the network but not to a neighboring network and transmitting at least user data in conjunction with the selected preamble signal. Another method for a network device of a powerline communications network includes tuning a sensor to detect network-specific preamble signals specific to the network but not to a neighboring network and receiving at least user data associated with the preamble signals.

A dental syringe including a hollow piston having threads on the inner wall thereof, and an exterior threaded rod disposable within the hollow piston and upon rotation of the rod moving the piston longitudinally for dispensing dental material from the syringe.
摘要:
A container (10) for mixing components, the container including a main body (12) defining a main chamber (17), a liquid receptacle (16), and a plunger (18). The main chamber has a distal end (26) which has an end cap (28). The main chamber also includes a central aperture (30) sealed by a frangible membrane (38). In use, the plunger causes liquid in the liquid receptacle to be pushed through an internal wall (22), having a weakened portion (24) therein, into the main chamber to mix the liquid with a powder contained in the main chamber. The liquid and powder are mixed to form a paste that is accessed by an applicator which is used to break the frangible membrane (38). The paste is preferably of the type used in dentistry.
